From f7ec3f62d7736ed14050716943a9562879155fcc Mon Sep 17 00:00:00 2001 From: Lukas Bulwahn Date: Thu, 8 Sep 2022 12:43:34 +0200 Subject: media: remove reference to CONFIG_EMBEDDED in MEDIA_SUPPORT_FILTER The config EMBEDDED selects EXPERT, i.e., when EMBEDDED is enabled, EXPERT is usually also enabled. Hence, it sufficient to have the option MEDIA_SUPPORT_FILTER set to y if !EXPERT. This way, MEDIA_SUPPORT_FILTER does not refer to CONFIG_EMBEDDED anymore and allows us to remove CONFIG_EMBEDDED in the close future. Remove the reference to CONFIG_EMBEDDED in MEDIA_SUPPORT_FILTER.

More importantly, the whole situation can be avoided and the driver simplified by converting it over to the relatively new usb_control_msg_recv() and usb_control_msg_send() routines. That's what this fix does.

Replace it with the correct macro, and rename it from RKISP1_CIF_ISP_LSC_GRAD_SIZE() to RKISP1_CIF_ISP_LSC_SECT_GRAD() as the corresponding registers store the gradients for each sector, not a size. This doesn't cause any functional change as the two macros are defined identically (the size and gradient registers store fields in the same number of bits at the same positions).

The driver currently configures all ISP initial parameters before enabling the ISP, which causes the LSC RAM to not be initialized properly. To fix this, split the rkisp1_params_configure() function into a rkisp1_params_pre_configure() and a rkisp1_params_post_configure(). The former configures all ISP parameters but LSC, while the latter configures LSC. To implement this, the rkisp1_params_apply_params_cfg() function is deconstructed, with two small helpers created to deal with the parameters buffers, which are then used in rkisp1_params_isr(), rkisp1_params_pre_configure() and rkisp1_params_post_configure(). While this initialization ordering is only needed for the ISP8000Nano v18.02, it doesn't affect other ISP versions negatively, and can thus be followed unconditionally.

As the drivers currently use the pipelines with the entity based model, moving the pipelines to pads will cause changes to the drivers. However, most of the uses of media pipelines are related to a video device (a DMA engine) with a single pad, and thus there's never a need to support multiple pads in these use cases. We can avoid pushing the complexities of the pad based model to the drivers by adding video device wrappers for the pipeline related functions. This patch adds a number of wrappers to media_pipeline functions, all of which take a video_device as a parameter (instead of a media_entity), and verify that there's just one pad.

The graph walk traverses the media graph following links between the entities. Also, while the pipeline can't change between the start and stop calls, the graph is walked again from scratch at stop time, or any time a driver needs to inspect the pipeline. With the upcoming multiplexed streams support we will need a bit more intelligent pipeline construction, as e.g. two independent streams may be passing through a single entity via separate pads in which case those pads should not be part of the same pipeline. This patch essentially rewrites the media_pipeline_start/stop so that a pipeline is defined as a set of pads instead of entities and the media graph traversal considers the pad interdependencies when choosing which links to follow. Currently all the entity's pads are considered as interdependent. This means that the behavior with all the current drivers stays the same, but in the future we can define a more fine-grained pipeline construction. Additionally the media pipeline's pads are cached at media_pipeline_start() time, and re-used at media_pipeline_stop() which avoid the need to re-walk the whole graph as the previous implementation did. Also, caching pads in the pipeline can serve in the future as the foundation to provide a better API than the media graph walk to drivers to iterate over pads and entities in the pipeline. Note that the old media_pipeline_start/stop used the media graph walk API. The new version does not use the media graph walk API, but instead a new implementation. There are two reasons for not changing the graph walk: it proved to be rather difficult to change the graph walk to have the features implemented in this patch, and second, this keeps the backward compatibility of the graph walk as there are users of the graph walk API The long term plan is that all the existing code would be converted to use the new cached pipeline, thus allowing us to remove the graph walk.

This fixes the following problem: 1. App does an VIDIOC_SET_FMT 640x480, calling ov2680_set_fmt() 2. Internal buffers (atomisp_create_pipes_stream()) get allocated at 640x480 size by atomisp_set_fmt() 3. ov2680_get_fmt() gets called later on and returns 1600x1200 since ov2680_device.dev was not updated. So things get configured to stream at 1600x1200, but the internal buffers created during atomisp_create_pipes_stream() do not get updated in size 4. streaming starts, internal buffers overflow and the entire machine freezes eventually due to memory being corrupted Reviewed-by: Andy Shevchenko Signed-off-by: Hans de Goede Signed-off-by: Mauro Carvalho Chehab --- drivers/staging/media/atomisp/i2c/atomisp-ov2680.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/drivers/staging/media/atomisp/i2c/atomisp-ov2680.c b/drivers/staging/media/atomisp/i2c/atomisp-ov2680.c index 4ba99c660681..ab52e35266bb 100644 --- a/drivers/staging/media/atomisp/i2c/atomisp-ov2680.c +++ b/drivers/staging/media/atomisp/i2c/atomisp-ov2680.c @@ -894,11 +894,7 @@ static int ov2680_set_fmt(struct v4l2_subdev *sd, if (v_flag) ov2680_v_flip(sd, v_flag); - /* - * ret = startup(sd); - * if (ret) - * dev_err(&client->dev, "ov2680 startup err\n"); - */ + dev->res = res; err: mutex_unlock(&dev->input_lock); return ret; -- cgit v1.2.3 From 44a11920ac39fe7fe5191d72c0822ff2a4c3b83d Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 13 Aug 2022 10:30:34 +0200 Subject: media: atomisp-ov2680: Don't take the input_lock for try_fmt calls.

Remove atomisp_file_fops and atomisp_file_ioctl_ops and all of the functions which are only referenced by these ops structs.

Yet it uses the same file-ops and ioctl-ops even though it does not have a videobuf queue, which makes e.g. the mmap fop nonsense. Worse the only file-ops / ioctls which differentiate between the 2 types and correctly do container_of on the right type are the open/release fops and the vidioc_default handler. The mmap and poll fops and *all* other ioctl handlers unconditionally do container_of on the passed in struct video_device blindly assuming they are dealing with the one embedded in the atomisp_video_pipe struct. This makes it trivial for userspace to cause all sort of undefined behavior by calling mmap, poll or the other ioctls on the ACC device node! Presumably the use of the ACC device node was to allow making the special ioctls to load custom programs while the other /dev/video# nodes were already open, since the /dev/video# nodes can currently all be opened only once (which needs to be fixed). commit 4bbca788b6eb ("media: atomisp: remove private acceleration ioctls") has removed the custom ATOMISP_ACC_* ioctls, so there no longer is any reason to keep the ACC device node. As explained above its presence can easily cause the kernel to crash, so remove the ACC device node and the code for handling it.

Writers of streaming must hold both isp->mutex and isp->lock. 2. Readers of streaming need to hold only one of the two locks. Not all writers where properly taking both locks this fixes this. In the case of the readers, many readers depend on their caller to hold isp->mutex, add asserts for this And in the case of atomisp_css_get_dis_stat() it is called with isp->mutex held, so there is no need to take the spinlock just for reading the streaming value.

Note this changes the vidioc_s_fmt_vid_cap and vidioc_s_input handlers to now reject calls made while asd->streaming==STOPPING. This fixes a possible race where one thread can make this ioctls while vidioc_streamoff is running from another thread and it has temporarily released isp->mutex to kill the watchdog timers / work.

There is no way to do fault injection and normally the ISP does not get stuck, so is it is impossible to test it. 2. It in essence just stops all streams, resets the ISP and then brings everything back up. Userspace can easily do this itself by using a timeout on dqbuf and then closing (which causes a poweroff) + re-opening the device. Doing this in userspace (if it ever turns out to be necessary) greatly simplifies the kernel code and in general will be a more robust solution. Even just a quick look at the code finds several more issues: 3. The need to sync-cancel the timers + work on streamoff requires isp->mutex to be dropped halfway during the ioctl opening all sorts of races. 4. The atomisp code supports setting up 2 pipelines, streaming from two sensors at the same time. But there is only a single wdt_work and stopping one of the 2 streams will cancel the timers + work, stopping the wdt even though the other stream might still be running. 5. In case atomisp_css_flush() the sync cancel is done while keeping isp->mutex locked, causing a deadlock when racing with wdt_work which also takes isp->mutex. 6. Even though the watchdog is purely a software/driver thing which just checkes that new frames keep coming in, there are 2 completely different implementations for the ISP2400/ISP2401 which is not necessary at all. So all in all I believe that it is better to just remove the current watchdog implementation. Fixing all the issues with the current implementation will be so much work, that if it turns out that we do need something like this then doing a clean re-implementation from scratch will be better anyways. wdt_work was also (ab)used to reset the ISP after the firmware signalled an fw-assert error through the irq, add a new assert_recover_work to replace this.

Otherwise the shrinker will see it as a thing that can be evicted if we wait for it to be signaled. But if the shrinker path is waiting on it with the obj lock held, the job cannot be scheduled, as that also requires briefly grabbing the obj lock, leading to deadlock.

There is a rare case that user space display manager issue an extra screen update immediately followed by close DRM device while down stream display interface is disabled. This extra screen update will timeout due to the downstream interface is disabled but will cause crtc->active be set. Hence the followed commit_tails() called by drm_release() will pass the disable downstream crtc/encoder/bridge conditions checking even downstream interface is disabled. This cause the crash to happen at dp_bridge_disable() due to it trying to access the main link register to push the idle pattern out while main link clocks is disabled. This patch adds atomic_check to prevent the extra frame will not be pushed down if display interface is down so that crtc->active will not be set neither. This will fail the conditions checking of disabling down stream crtc/encoder/bridge which prevent drm_release() from calling dp_bridge_disable() so that crash at dp_bridge_disable() prevented. There is no protection in the DRM framework to check if the display pipeline has been already disabled before trying again. The only check is the crtc_state->active but this is controlled by usermode using UAPI. Hence if the usermode sets this and then crashes, the driver needs to protect against double disable.

We only need to make sure that the returned root_cgrp won't be freed under us. This is given in the case of global root because it is static (cgrp_dfl_root.cgrp). When the root_cgrp is lower in the hierarchy, it is pinned by cgroup_ns->root_cset (and `current` task cannot switch namespace asynchronously so ns_proxy pins cgroup_ns). Note this reasoning won't hold for root cgroups in v1 hierarchies, therefore create a special-cased helper function just for the default hierarchy.

This is wrong, because: 1) This might be a DROP reference that will cancel out a reference in the extent tree; 2) Even if it's an ADD reference, it may be followed by a DROP reference that cancels it out. In either case we should not exit immediately. Fix this by never exiting when we find a delayed data reference for another inode - instead add the reference and if it does not cancel out other delayed reference, we will exit early when we call extent_is_shared() after processing all delayed references. If we find a drop reference, then signal the code that processes references from the extent tree (add_inline_refs() and add_keyed_refs()) to not exit immediately if it finds there a reference for another inode, since we have delayed drop references that may cancel it out. In this later case we exit once we don't have references in the rb trees that cancel out each other and have two references for different inodes.

This is wrong, because indirect references should have a NULL key when we don't have access to the key, and in that case they should be added to the indirect_missing_keys rb tree and not to the indirect rb tree. This means that if have BTRFS_TREE_BLOCK_REF_KEY delayed ref resulting from freeing an extent buffer, therefore with a count of -1, it will not cancel out the corresponding reference we have in the extent tree (with a count of 1), since both references end up in different rb trees. When using fiemap, where we often need to check if extents are shared through shared subtrees resulting from snapshots, it means we can incorrectly report an extent as shared when it's no longer shared. However this is temporary because after the transaction is committed the extent is no longer reported as shared, as running the delayed reference results in deleting the tree block reference from the extent tree. Outside the fiemap context, the result is unpredictable, as the key was not initialized but it's used when navigating the rb trees to insert and search for references (prelim_ref_compare()), and we expect all references in the indirect rb tree to have valid keys. The following reproducer triggers the second bug: $ cat test.sh #!/bin/bash DEV=/dev/sdj MNT=/mnt/sdj mkfs.btrfs -f $DEV mount -o compress $DEV $MNT # With a compressed 128M file we get a tree height of 2 (level 1 root). xfs_io -f -c "pwrite -b 1M 0 128M" $MNT/foo btrfs subvolume snapshot $MNT $MNT/snap # Fiemap should output 0x2008 in the flags column. # 0x2000 means shared extent # 0x8 means encoded extent (because it's compressed) echo echo "fiemap after snapshot, range [120M, 120M + 128K):" xfs_io -c "fiemap -v 120M 128K" $MNT/foo echo # Overwrite one extent and fsync to flush delalloc and COW a new path # in the snapshot's tree. # # After this we have a BTRFS_DROP_DELAYED_REF delayed ref of type # BTRFS_TREE_BLOCK_REF_KEY with a count of -1 for every COWed extent # buffer in the path. # # In the extent tree we have inline references of type # BTRFS_TREE_BLOCK_REF_KEY, with a count of 1, for the same extent # buffers, so they should cancel each other, and the extent buffers in # the fs tree should no longer be considered as shared. # echo "Overwriting file range [120M, 120M + 128K)..." xfs_io -c "pwrite -b 128K 120M 128K" $MNT/snap/foo xfs_io -c "fsync" $MNT/snap/foo # Fiemap should output 0x8 in the flags column.

Having a single path is by far the most common case, and therefore worth to optimize for, but it's possible to actually have multiple paths because we have 2 or more leaves. If we have multiple leaves, the 'level' variable keeps getting incremented in each iteration of the while loop at btrfs_is_data_extent_shared(), which means we will treat the second leaf in the 'tmp' ulist as a level 1 node, and so forth. In the worst case this can lead to getting a level greater than or equals to BTRFS_MAX_LEVEL (8), which will trigger a WARN_ON_ONCE() in the functions to lookup from or store in the path cache (lookup_backref_shared_cache() and store_backref_shared_cache()). If the current level never goes beyond 8, due to shared nodes in the paths and a fs tree height smaller than 8, it can still result in incorrectly marking one leaf as shared because some other leaf is shared and is stored one level below that other leaf, as when storing a true sharedness value in the cache results in updating the sharedness to true of all entries in the cache below the current level. Having multiple leaves happens in a case like the following: - We have a file extent item point to data extent at bytenr X, for a file range [0, 1M[ for example; - At this moment we have an extent data ref for the extent, with an offset of 0 and a count of 1; - A write into the middle of the extent happens, file range [64K, 128K) so the file extent item is split into two (at btrfs_drop_extents()): 1) One for file range [0, 64K), with a length (num_bytes field) of 64K and an extent offset of 0; 2) Another one for file range [128K, 1M), with a length of 896K (1M - 128K) and an extent offset of 128K. - At this moment the two file extent items are located in the same leaf; - A new file extent item for the range [64K, 128K), pointing to a new data extent, is inserted in the leaf. This results in a leaf split and now those two file extent items pointing to data extent X end up located in different leaves; - Once delayed refs are run, we still have a single extent data ref item for our data extent at bytenr X, for offset 0, but now with a count of 2 instead of 1; - So during fiemap, at btrfs_is_data_extent_shared(), after we call find_parent_nodes() for the data extent, we get two leaves, since we have two file extent items point to data extent at bytenr X that are located in two different leaves. So skip the use of the path cache when we get more than one leaf.

In such a case, the module loader will have a very narrow window to load the module between the device registration and the card registration. If it fails to load the module in time, the card registration will fail with EPROBE_DEFER, and we'll abort the audio initialisation, unregistering the HDMI codec device in the process. The next time the bind callback will be run, it's likely that we end up missing that window again, effectively preventing vc4 to probe entirely. In order to prevent this, we can create a soft dependency of the vc4 driver on the HDMI codec one so that we're sure the HDMI codec will be loaded before the VC4 module is, and thus we'll never end up in the previous situation.

It turns out that we can't downright remove that code from the driver, since the Pi0-3 and Pi4 are in different cases, and it only works for the Pi4. Indeed, the commit mentioned above was relying on the RaspberryPi firmware clocks driver to initialize the rate if it wasn't done by the firmware. However, the Pi0-3 are using the clk-bcm2835 clock driver that wasn't doing this initialization. We therefore end up with the clock not being assigned a rate, and the CPU stalling when trying to access a register. We can't move that initialization in the clk-bcm2835 driver, since the HSM clock we depend on is actually part of the HDMI power domain, so any rate setup is only valid when the power domain is enabled. Thus, we reinstated the minimum rate setup at runtime_suspend, which should address both issues.

The API is meant to allow the callback to return 0 if it wants to continue draining samples, and 1 if it's done draining. Unfortunately, bpf_user_ringbuf_drain() landed shortly after commit 1bfe26fb0827 ("bpf: Add verifier support for custom callback return range"), which changed the default behavior of callbacks to only support returning 0. This patch corrects that oversight by allowing bpf_user_ringbuf_drain() callbacks to return 0 or 1.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Changing a VF's mac address through the VF (rather than via the PF) fails with EPERM because the latter part of efx_ef10_set_mac_address attempts to change the vport mac address list as the VF. Even with this fixed it still fails with EBUSY because the vadaptor is still assigned on the VF - the vadaptor reassignment must be within a section where the VF has torn down its state. A major reason this has broken is because we have two functions that ostensibly do the same thing - have a PF and VF cooperate to change a VF mac address. Rather than do this, if we are changing the mac of a VF that has a link to the PF in the same VM then simply call sriov_set_vf_mac instead, which is a proven working function that does that. If there is no PF available, or that fails non-fatally, then attempt to change the VF's mac address as we would a PF, without updating the PF's data. Test case: Create a VF: echo 1 > /sys/class/net//device/sriov_numvfs Set the mac address of the VF directly: ip link set addr 00:11:22:33:44:55 Set the MAC address of the VF via the PF: ip link set vf 0 mac 00:11:22:33:44:66 Without this patch the last command will fail with ENOENT.

Reproducer hints: 1. Create ARM virt VM with pxb-pcie bus which adds extra host bridges, with qemu command like: ``` -device pxb-pcie,bus_nr=8,id=pci.x,numa_node=0,bus=pcie.0 \ -device pcie-root-port,..,bus=pci.x \ ... -device pxb-pcie,bus_nr=37,id=pci.y,numa_node=1,bus=pcie.0 \ -device pcie-root-port,..,bus=pci.y \ ... ``` 2. Ensure the guest uses 2-level device table 3. Perform VM migration which calls save/restore device tables In that setup, we get a big "offset" between 2 device_ids, which makes unsigned "len" round up a big positive number, causing the scan loop to continue with a bad GPA. For example: 1. L1 table has 2 entries; 2. and we are now scanning at L2 table entry index 2075 (pointed to by L1 first entry) 3. if next device id is 9472, we will get a big offset: 7397; 4. with unsigned 'len', 'len -= offset * esz', len will underflow to a positive number, mistakenly into next iteration with a bad GPA; (It should break out of the current L2 table scanning, and jump into the next L1 table entry) 5. that bad GPA fails the guest read. Fix it by stopping the L2 table scan when the next device id is outside of the current table, allowing the scan to continue from the next L1 table entry. Thanks to Eric Auger for the fix suggestion.

Arguably, getting the one that's running the code in there is confusing. For this reason, simply give the control CPU role to the first online one which automatically will be CPU0 if it is online, so one check can be dropped from the code for an added benefit.

I'll re-summarize here but you can also re-read the original commit. On trogdor devices, the BIOS is setting up the SPI chip select as: - mux special function (SPI chip select) - output enable - output low (unused because we've muxed as special function) In the kernel, however, we've moved away from using the chip select line as special function. Since the kernel wants to fully control the chip select it's far more efficient to treat the line as a GPIO rather than sending packet-like commands to the GENI firmware every time we want the line to toggle. When we transition from how the BIOS had the pin configured to how the kernel has the pin configured we end up glitching the line. That's because we _first_ change the mux of the line and then later set its output. This glitch is bad and can confuse the device on the other end of the line. The old commit e440e30e26dd ("arm64: dts: qcom: sc7180: Avoid glitching SPI CS at bootup on trogdor") fixed the glitch, though the solution was far from elegant. It essentially did the thing that everyone always hates: encoding a sequential program in device tree, even if it's a simple one. It also, unfortunately, got broken by commit b991f8c3622c ("pinctrl: core: Handling pinmux and pinconf separately"). After that commit we did all the muxing _first_ even though the config (set the pin to output high) was listed first. :( I looked at ideas for how to solve this more properly. My first thought was to use the "init" pinctrl state. In theory the "init" pinctrl state is supposed to be exactly for achieving glitch-free transitions. My dream would have been for the "init" pinctrl to do nothing at all. That would let us delay the automatic pin muxing until the driver could set things up and call pinctrl_init_done(). In other words, my dream was: /* Request the GPIO; init it 1 (because DT says GPIO_ACTIVE_LOW) */ devm_gpiod_get_index(dev, "cs", GPIOD_OUT_LOW); /* Output should be right, so we can remux, yay! */ pinctrl_init_done(dev); Unfortunately, it didn't work out. The primary reason is that the MSM GPIO driver implements gpio_request_enable(). As documented in pinmux.h, that function automatically remuxes a line as a GPIO. ...and it does this remuxing _before_ specifying the output of the pin. You can see in gpiod_get_index() that we call gpiod_request() before gpiod_configure_flags(). gpiod_request() isn't passed any flags so it has no idea what the eventual output will be. We could have debates about whether or not the automatic remuxing to GPIO for the MSM pinctrl was a good idea or not, but at this point I think there is a plethora of code that's relying on it and I certainly wouldn't suggest changing it. Alternatively, we could try to come up with a way to pass the initial output state to gpio_request_enable() and plumb all that through. That seems like it would be doable, but we'd have to plumb it through several layers in the stack. This patch implements yet another alternative. Here, we specifically avoid glitching the first time a pin is muxed to GPIO function if the direction of the pin is output. The idea is that we can read the state of the pin before we set the mux and make sure that the re-mux won't change the state. NOTES: - We only do this the first time since later swaps between mux states might want to preserve the old output value. In other words, I wouldn't want to break a driver that did: gpiod_set_value(g, 1); pinctrl_select_state(pinctrl, special_state); pinctrl_select_default_state(); /* We should be driving 1 even if "special_state" made the pin 0 */ - It's safe to do this the first time since the driver _couldn't_ have explicitly set a state. In order to even be able to control the GPIO (at least using gpiod) we have to have requested it which would have counted as the first mux. - In theory, instead of keeping track of the first time a pin was set as a GPIO we could enable the glitch-free behavior only when msm_pinmux_request_gpio() is in the callchain. That works an enables my "dream" implementation above where we use an "init" state to solve this. However, it's nice not to have to do this. By handling just the first transition to GPIO we can simply let the normal "default" remuxing happen and we can be assured that there won't be a glitch. Before this change I could see the glitch reported on the EC console when booting. It would say this when booting the kernel: Unexpected state 1 in CSNRE ISR After this change there is no error reported. Note that I haven't reproduced the original problem described in e440e30e26dd ("arm64: dts: qcom: sc7180: Avoid glitching SPI CS at bootup on trogdor") but I could believe it might happen in certain timing conditions.

Missing SIGTRAP due to a race with event_sched_out() (more details below). 2. Hardware PMU events being disabled due to returning 1 from perf_event_overflow(). The only way to re-enable the event is for user space to first "properly" disable the event and then re-enable it. 3. The inability to automatically disable an event after a specified number of overflows via PERF_EVENT_IOC_REFRESH. The worst of the 3 issues is problem (1), which occurs when a pending_disable is "consumed" by a racing event_sched_out(), observed as follows: CPU0 | CPU1 --------------------------------+--------------------------- __perf_event_overflow() | perf_event_disable_inatomic() | pending_disable = CPU0 | ... | _perf_event_enable() | event_function_call() | task_function_call() | /* sends IPI to CPU0 */ | ... __perf_event_enable() +--------------------------- ctx_resched() task_ctx_sched_out() ctx_sched_out() group_sched_out() event_sched_out() pending_disable = -1 perf_pending_event() perf_pending_event_disable() /* Fails to send SIGTRAP because no pending_disable! */ In the above case, not only is that particular SIGTRAP missed, but also all future SIGTRAPs because 'event_limit' is not reset back to 1. To fix, rework pending delivery of SIGTRAP via IRQ-work by introduction of a separate 'pending_sigtrap', no longer using 'event_limit' and 'pending_disable' for its delivery. Additionally; and different to Marco's proposed patch: - recognise that pending_disable effectively duplicates oncpu for the case where it is set. As such, change the irq_work handler to use ->oncpu to target the event and use pending_* as boolean toggles. - observe that SIGTRAP targets the ctx->task, so the context switch optimization that carries contexts between tasks is invalid. If the irq_work were delayed enough to hit after a context switch the SIGTRAP would be delivered to the wrong task. - observe that if the event gets scheduled out (rotation/migration/context-switch/...) the irq-work would be insufficient to deliver the SIGTRAP when the event gets scheduled back in (the irq-work might still be pending on the old CPU). Therefore have event_sched_out() convert the pending sigtrap into a task_work which will deliver the signal at return_to_user.

Commit 8bb7ff12a914 ("PCI: tegra: Use PCI_CONF1_EXT_ADDRESS() macro") updated the Tegra PCI driver to use the macro PCI_CONF1_EXT_ADDRESS() instead of a local function in the Tegra PCI driver. This broke PCI for some Tegra platforms because, when calculating the offset value, the mask applied to the lower 8-bits changed from 0xff to 0xfc. For now, fix this by reverting this commit.

Lack of CONFIG_EFI_STUB can prevent kernels from booting via EFI in certain circumstances. This check was added by 8f24f8c2fc82 ("efi/libstub: Annotate firmware routines as __efiapi") to ensure that __attribute__((ms_abi)) was available, as -mabi=ms is not actually used in any cflags. According to the GCC documentation, this attribute has been supported since GCC 4.4.7. The kernel currently requires GCC 5.1 so this check is not necessary; even when that change landed in 5.6, the kernel required GCC 4.9 so it was unnecessary then as well. Clang supports __attribute__((ms_abi)) for all versions that are supported for building the kernel so no additional check is needed. Remove the 'depends on' line altogether to allow CONFIG_EFI_STUB to be selected when CONFIG_EFI is enabled, regardless of compiler.

Current code gets package ID by shifting out all the APIC-ID bits that Linux supports, rather than shifting out all the APIC-ID bits that CPUID.1F enumerates. This introduces problems when CPUID.1F enumerates a level that Linux does not support. For example, on a single package AlderLake-N, there are 2 Ecore Modules with 4 atom cores in each module. Linux does not support the Module level and interprets the Module ID bits as package ID and erroneously reports a multi module system as a multi-package system. Fix this by using APIC-ID bits above all the CPUID.1F enumerated levels as package ID.

But an AlderLake-N platform adds a Module level between core and package, Linux excludes the unknown modules bits from the core ID, resulting in duplicate core ID's. To keep core ID unique within a package, Linux must include all APIC-ID bits for known or unknown levels above the core and below the package in the core ID. It is important to understand that core ID's have always come directly from the APIC-ID encoding, which comes from the BIOS. Thus there is no guarantee that they start at 0, or that they are contiguous. As such, naively using them for array indexes can be problematic.

Memory allocated for page table entries not released during process termination. This issue can be reproduced by a small program that allocates a large amount of memory. After several runs, you'll see that the amount of free memory has reduced and will continue to reduce after each run. All ARC CPUs are effected by this issue. The issue was introduced since the kernel stable release v5.15-rc1. As described in commit d9820ff after switch pgtable_t back to struct page *, a pointer to "struct page" and appropriate functions are used to allocate and free a memory page for PTEs, but the pmd_pgtable macro hasn't changed and returns the direct virtual address from the PMD (PGD) entry. Than this address used as a parameter in the __pte_free() and as a result this function couldn't release memory page allocated for PTEs. Fix this issue by changing the pmd_pgtable macro and returning pointer to struct page.

This causes issues because proper transitioning out of some states involves steps besides just changing sdev_state, so allowing userspace to change sdev_state regardless of the source state can result in inconsistencies; e.g. with ISCSI we can end up with sdev_state == SDEV_RUNNING while the device queue is quiesced.

Upon failure on the VMID allocations, the new code would branch to the 'out' label, which returns NULL without unwinding anything, thus skipping the call to scsi_host_put(). Fix the problem by creating a separate label 'out_free_vmid' to unwind the VMID resources and make the 'out_put_shost' label call only scsi_host_put(), as was done before the introduction of allocations for VMID.

When we call connect() for a UDP socket in a reuseport group, we have to update sk->sk_reuseport_cb->has_conns to 1. Otherwise, the kernel could select a unconnected socket wrongly for packets sent to the connected socket. However, the current way to set has_conns is illegal and possible to trigger that problem. reuseport_has_conns() changes has_conns under rcu_read_lock(), which upgrades the RCU reader to the updater. Then, it must do the update under the updater's lock, reuseport_lock, but it doesn't for now. For this reason, there is a race below where we fail to set has_conns resulting in the wrong socket selection. To avoid the race, let's split the reader and updater with proper locking. cpu1 cpu2 +----+ +----+ __ip[46]_datagram_connect() reuseport_grow() . . |- reuseport_has_conns(sk, true) |- more_reuse = __reuseport_alloc(more_socks_size) | . | | |- rcu_read_lock() | |- reuse = rcu_dereference(sk->sk_reuseport_cb) | | | | | /* reuse->has_conns == 0 here */ | | |- more_reuse->has_conns = reuse->has_conns | |- reuse->has_conns = 1 | /* more_reuse->has_conns SHOULD BE 1 HERE */ | | | | | |- rcu_assign_pointer(reuse->socks[i]->sk_reuseport_cb, | | | more_reuse) | `- rcu_read_unlock() `- kfree_rcu(reuse, rcu) | |- sk->sk_state = TCP_ESTABLISHED Note the likely(reuse) in reuseport_has_conns_set() is always true, but we put the test there for ease of review. [0] For the record, usually, sk_reuseport_cb is changed under lock_sock(). The only exception is reuseport_grow() & TCP reqsk migration case. 1) shutdown() TCP listener, which is moved into the latter part of reuse->socks[] to migrate reqsk. 2) New listen() overflows reuse->socks[] and call reuseport_grow(). 3) reuse->max_socks overflows u16 with the new listener. 4) reuseport_grow() pops the old shutdown()ed listener from the array and update its sk->sk_reuseport_cb as NULL without lock_sock(). shutdown()ed TCP sk->sk_reuseport_cb can be changed without lock_sock(), but, reuseport_has_conns_set() is called only for UDP under lock_sock(), so likely(reuse) never be false in reuseport_has_conns_set().

Therefore, on SMT designs where the microcode engine is shared between the two threads, the application happens only on one of them as that is enough to update the shared microcode engine. However, there are microcode patches which do per-thread modification, see Link tag below. Therefore, drop the revision check and try applying on each thread. This is what the BIOS does too so this method is very much tested. Btw, change only the early paths. On the late loading paths, there's no point in doing per-thread modification because if is it some case like in the bugzilla below - removing a CPUID flag - the kernel cannot go and un-use features it has detected are there early. For that, one should use early loading anyway.

The following line defines a pointer that point to a char buffer stored in read-only memory: char *pvs_name = "speedXX-pvsXX-vXX"; This pointer is meant to hold a template "speedXX-pvsXX-vXX" where the XX values get overridden by the qcom_cpufreq_krait_name_version function. Since the template is actually stored in read-only memory, when the function executes the following call we get an oops: snprintf(*pvs_name, sizeof("speedXX-pvsXX-vXX"), "speed%d-pvs%d-v%d", speed, pvs, pvs_ver); To fix this issue, we instead store the template name onto the stack by using the following syntax: char pvs_name_buffer[] = "speedXX-pvsXX-vXX"; Because the `pvs_name` needs to be able to be assigned to NULL, the template buffer is stored in the pvs_name_buffer and not under the pvs_name variable.

But this IRQ disable sets the VAS IRQ OFF state in the hypervisor. In case if NX faults during this window, the hypervisor will not deliver the fault interrupt to the partition and the user space may wait continuously for the CSB update. So use VAS specific IRQ handler instead of calling the default primary handler. Increment pending_faults counter in IRQ handler and the bottom thread handler will process all faults based on this counter. In case if the another interrupt is received while the thread is running, it will be processed using this counter. The synchronization of top and bottom handlers will be done with IRQTF_RUNTHREAD flag and will re-enter to bottom half if this flag is set.

This breaks if a PMI hits after interrupt_exit_user_prepare_main() has switched the context tracking to user mode, then the CT_WARN_ON() in interrupt_exit_kernel_prepare() fires because it returns to kernel with context set to user. This could possibly be solved by soft-disabling PMIs in the exit path, but that reduces our ability to profile that code. The warning could be removed, but it's potentially useful.

Address this by partially reverting commit 4919d3eb2ec0 so that cmos_wake_setup() is called before cmos_do_probe() again and moving the rtc_wake_setup() invocation from cmos_wake_setup() directly to the callers of cmos_do_probe() where it will happen after a successful completion of the latter.

When the filesystem is remounted, recovery will try to replay the committed rmap intent item, but the corruption problem causes the recovery transaction to fail. Cancelling the transaction frees the RUD, which frees the RUI that we recovered. When we return to xlog_recover_process_intents, @lip is now a dangling pointer, and we cannot use it to find the iop_recover method for the tracepoint. Hence we must store the item ops before calling ->iop_recover if we want to give it to the tracepoint so that the trace data will tell us exactly which intent item failed. Signed-off-by: Darrick J.

Currently netfilter's rpfilter and fib modules implicitely initialise ->flowic_uid with 0. This is normally the root UID. However, this isn't the case in user namespaces, where user ID 0 is mapped to a different kernel UID. By initialising ->flowic_uid with sock_net_uid(), we get the root UID of the user namespace, thus keeping the same behaviour whether or not we're running in a user namepspace.

It turned out that the nvme_get_log() method invocation caused the nvme_hwmon_data structure instance corruption. In particular the nvme_hwmon_data.ctrl pointer was overwritten either with zeros or with garbage. After some research we discovered that the problem happened even before the actual NVME DMA execution, but during the buffer mapping. Since our platform is DMA-noncoherent, the mapping implied the cache-line invalidations or write-backs depending on the DMA-direction parameter. In case of the NVME SMART log getting the DMA was performed from-device-to-memory, thus the cache-invalidation was activated during the buffer mapping. Since the log-buffer isn't cache-line aligned, the cache-invalidation caused the neighbour data to be discarded. The neighbouring data turned to be the data surrounding the buffer in the framework of the nvme_hwmon_data structure. In order to fix that we need to make sure that the whole log-buffer is defined within the cache-line-aligned memory region so the cache-invalidation procedure wouldn't involve the adjacent data. One of the option to guarantee that is to kmalloc the DMA-buffer [1]. Seeing the rest of the NVME core driver prefer that method it has been chosen to fix this problem too. Note after a deeper researches we found out that the denoted commit wasn't a root cause of the problem. It just revealed the invalidity by activating the DMA-based NVME SMART log getting performed in the framework of the NVME hwmon driver. The problem was here since the initial commit of the driver.

A DAI link is only created as DPCM if the device tree requires it; part of this involves checking for the use of "convert-xxx" properties. When the convert-sample-format property was added, the checks got out of sync. A DAI link that specified only convert-sample-format but did not pass any of the other DPCM checks would not go into DPCM mode and the convert-sample-format property would be silently ignored. Fix this by adding a function to do the "convert-xxx" property checks, instead of open-coding it in simple-card and audio-graph-card. And add "convert-sample-format" to the check function so that DAI links using it will be initialized correctly.

This causes a problem in the kernel tcp stack when having a egress tc rule forwarding to a ingress tc rule. The tcp stack sending packets on the device having the egress rule will see the packets as not successfully transmitted (although they actually were), will not advance it's internal state of sent data, and packets returning on such tcp stream will be dropped by the tcp stack with reason ack-of-unsent-data.

It was found that within a critical section of spin_lock_irqsave in sidtab_context_to_sid(), convert_context() (hooked by sidtab_convert_params.func) might cause the process to sleep via allocating memory with GFP_KERNEL, which is problematic. As Ondrej pointed out [1], convert_context()/sidtab_convert_params.func has another caller sidtab_convert_tree(), which is okay with GFP_KERNEL. Therefore, fix this problem by adding a gfp_t argument for convert_context()/sidtab_convert_params.func and pass GFP_KERNEL/_ATOMIC properly in individual callers.

Unfortunately, this causes a memory leak in the case where a mount is attempted with the test_dummy_encryption mount option, but the mount fails after the option has already been processed.

The problem is that this accesses device->ldev->backing_bdev, which is not NULL-checked at this point. When we don't have an ldev (i.e. when the DRBD device is diskless), this leads to a null pointer deref. So, only allocate the private_bio if we actually have a disk. This is also a small optimization, since we don't clone the bio to only to immediately free it again in the diskless case.

This reordering uncovered a different hw programming ordering dependency in some APUs where the SDMA doorbells need to be programmed before the GFX doorbells. To fix this, move the SDMA doorbell programming back into the soc15 common code, but use the actual doorbell range values directly rather than the values stored in the ring structure since those will not be initialized at this point. This is a partial revert, but with the doorbell assignment fixed so the proper doorbell index is set before it's used.

The page lock is supposed to prevent this from happening but in the following case it doesn't: Two fuse_add_dirent_to_cache() start out and get the same parameters (size=0,offset=0). One of them wins the race to create and lock the page, after which it fills in data, sets rdc.size and unlocks the page. In the meantime the page gets evicted from the cache before the other instance gets to run. That one also creates the page, but finds the size to be mismatched, bails out and leaves the uninitialized page in the cache. Fix by marking a filled page uptodate and ignoring non-uptodate pages.

McKenney" Date: Thu, 20 Oct 2022 10:58:14 -0700 Subject: rcu: Keep synchronize_rcu() from enabling irqs in early boot Making polled RCU grace periods account for expedited grace periods required acquiring the leaf rcu_node structure's lock during early boot, but after rcu_init() was called. This lock is irq-disabled, but the code incorrectly assumes that irqs are always disabled when invoking synchronize_rcu(). The exception is early boot before the scheduler has started, which means that upon return from synchronize_rcu(), irqs will be incorrectly enabled.

The CXL specification allows a host bridge with a single root port to have no explicit HDM decoders. Currently the region driver assumes there are none. As such the CXL core creates a special pass through decoder instance without a commit callback. Prior to this patch, the ->commit() callback was called unconditionally. Thus a configuration with 1 Host Bridge, 1 Root Port, 1 switch with multiple downstream ports below which there are multiple CXL type 3 devices results in a situation where committing the region causes a null pointer dereference.

To ensure the lsock is not released during the tipc_topsrv_accept(), move sock_release() after tipc_topsrv_work_stop() where it's waiting until the tipc_topsrv_accept worker to be done. Note that sk_callback_lock is used to protect sk->sk_user_data instead of srv->listener, and it should check srv in tipc_topsrv_listener_data_ready() instead. This also ensures that no more tipc_topsrv_accept worker will be started after tipc_conn_close() is called in tipc_topsrv_stop() where it sets sk->sk_user_data to null.

The root cause was traced to an error path in mmap_region when mas_preallocate() fails. In this case, the vma is freed after a successful call to filesystem specific mmap. The hugetlbfs mmap routine may allocate data structures pointed to by m_private_data. These need to be cleaned up by the hugetlb vm_ops->close() routine. The same issue was addressed by commit deb0f6562884 ("mm/mmap: undo ->mmap() when arch_validate_flags() fails") for the arch_validate_flags() test. Go to the same close_and_free_vma label if mas_preallocate() fails.

The structure is vma specific and can not be shared between vmas. At fork and various other times, vmas are duplicated via vm_area_dup(). When this happens, the pointer in the newly created vma must be cleared and the structure reallocated. Two hugetlb specific routines deal with this hugetlb_dup_vma_private and hugetlb_vm_op_open. Both routines are called for newly created vmas. hugetlb_dup_vma_private would always clear the pointer and hugetlb_vm_op_open would allocate the new vms_lock structure. This did not work in the case of this calling sequence pointed out in [1]. move_vma copy_vma new_vma = vm_area_dup(vma); new_vma->vm_ops->open(new_vma); --> new_vma has its own vma lock. is_vm_hugetlb_page(vma) clear_vma_resv_huge_pages hugetlb_dup_vma_private --> vma->vm_private_data is set to NULL When clearing hugetlb_dup_vma_private we actually leak the associated vma_lock structure. The vma_lock structure contains a pointer to the associated vma. This information can be used in hugetlb_dup_vma_private and hugetlb_vm_op_open to ensure we only clear the vm_private_data of newly created (copied) vmas. In such cases, the vma->vma_lock->vma field will not point to the vma. Update hugetlb_dup_vma_private and hugetlb_vm_op_open to not clear vm_private_data if vma->vma_lock->vma == vma. Also, log a warning if hugetlb_vm_op_open ever encounters the case where vma_lock has already been correctly allocated for the vma.

This patch only clobbers page->private for tail pages if the head page was not in swapcache and warns once if page->private had an unexpected value.

Unfortunately the corresponding update to Nouveau to accommodate this change was inadvertently dropped from that patch causing GPU to CPU migration to fail so add it here.

This function returns incorrect value when Sstc is available because the per-VCPU next_cycles are only updated by kvm_riscv_vcpu_timer_save() called from kvm_arch_vcpu_put(). As a result, when Sstc is available the VCPU does not block properly upon WFI traps. To fix the above issue, we introduce kvm_riscv_vcpu_timer_sync() which will update per-VCPU next_cycles upon every VM exit instead of kvm_riscv_vcpu_timer_save().

The ACPI spec https://uefi.org/specs/ACPI/6.5/15_System_Address_Map_Interfaces.html uses similar wording for "Reserved" and "NVS" region types; for NVS regions it says "This range of addresses is in use or reserved by the system and must not be used by the operating system." There is an old comment on this mailing list that also suggests NVS regions should pass the arch_rmrr_sanity_check() test: The warnings come from arch_rmrr_sanity_check() since it checks whether the region is E820_TYPE_RESERVED. However, if the purpose of the check is to detect RMRR has regions that may be used by OS as free memory, isn't E820_TYPE_NVS safe, too?

This was necessary because there are actually two images that need to be signed: the kernel with the EFI stub attached, and the decompressor application. This is a bit of a burden, because it means that the images must be signed on the the same system that performs the build, and this is not realistic for distros. During the next cycle, we will introduce changes to the zboot code so that the inner image no longer needs to be signed. This means that the outer PE/COFF image can be handled as usual, and be signed later in the release process. Let's remove the associated Kconfig options now so that they don't end up in a LTS release while already being deprecated.

This inadvertently broke setting variables on firmware implementations that lack the QueryVariableInfo() boot service, because we no longer tolerate a EFI_UNSUPPORTED result from check_var_size() when calling efivar_entry_set_get_size(), which now ends up calling check_var_size() a second time inadvertently.

In this case, it populates the virtual address fields of the runtime regions in the memory map with the physical address of each region, so that the mapping code has to be none the wiser. Only if SetVirtualAddressMap() fails, the virtual addresses are wiped and the kernel code knows that the regions cannot be mapped. However, wiping amounts to setting it to zero, and if a runtime region happens to live at physical address 0, its valid 1:1 mapped virtual address could be mistaken for a wiped field, resulting on loss of access to the EFI services at runtime.

While I'm always a fan of removing mysterious delays, I suspect that we need this mysterious delay to avoid some problems. Specifically, what I found recently is that on sc7180-trogdor-homestar sometimes the AUX backlight wasn't initializing properly. Some debugging showed that the drm_dp_dpcd_read() function that the AUX backlight driver was calling was returning bogus data about 1% of the time when I booted up. This confused drm_panel_dp_aux_backlight(). From continued debugging: - If I retried the read then the read worked just fine. - If I added a loop to perform the same read that drm_panel_dp_aux_backlight() was doing 30 times at bootup I could see that some percentage of the time the first read would give bogus data but all 29 additional reads would always be fine. - If I added a large delay _after_ powering on the panel but before powering on PS8640 I could still reproduce the problem. - If I added a delay after PS8640 powered on then I couldn't reproduce the problem. - I couldn't reproduce the problem on a board with the same panel but the ti-sn65dsi86 bridge chip. To me, the above indicated that there was a problem with PS8640 and not the panel. I don't really have any insight into what's going on in the MCU, but my best guess is that when the MCU itself sees the HPD go high that it does some AUX transfers itself and this is confusing things. Let's go back and add back in the mysterious 50 ms delay. We only want to do this the first time we see HPD go high after booting the MCU, not every time we double-check HPD. With this, the backlight initializes reliably on homestar.

When destroying bpf memory allocator, refill_work may be busy for PREEMPT_RT kernel in which irq work is invoked in a per-CPU RT-kthread. It is also possible for kernel with arch_irq_work_has_interrupt() being false (e.g. 1-cpu arm32 host or mips) and irq work is inovked in timer interrupt. The busy refill_work leads to various issues. The obvious one is that there will be concurrent operations on free_by_rcu and free_list between irq work and memory draining. Another one is call_rcu_in_progress will not be reliable for the checking of pending RCU callback because do_call_rcu() may have not been invoked by irq work yet. The other is there will be use-after-free if irq work is freed before the callback of irq work is invoked as shown below: BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor instruction fetch in kernel mode #PF: error_code(0x0010) - not-present page PGD 12ab94067 P4D 12ab94067 PUD 1796b4067 PMD 0 Oops: 0010 [#1] PREEMPT_RT SMP CPU: 5 PID: 64 Comm: irq_work/5 Not tainted 6.0.0-rt11+ #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996) RIP: 0010:0x0 Code: Unable to access opcode bytes at 0xffffffffffffffd6.

Without the PLL control setting, the link up takes longer time in a fixed phy configuration. Driver implements SW RRC for Autoneg On configuration, hence PLL control setting (RRC) is not needed for AN On configuration, and can be skipped. Also, PLL re-initialization is not needed for PHY Power Off and RRC commands. Otherwise, they lead to mailbox errors. Added the changes accordingly.

However, runtime services data is intended for allocations that are relevant to the implementations of the runtime services themselves, and so they are unmapped from the kernel linear map, and mapped into the EFI page tables that are active while runtime service invocations are in progress. None of this is needed for the RNG seed. So let's switch to EFI 'ACPI reclaim' memory: in spite of the name, there is nothing exclusively ACPI about it, it is simply a type of allocation that carries firmware provided data which may or may not be relevant to the OS, and it is left up to the OS to decide whether to reclaim it after having consumed its contents. Given that in Linux, we never reclaim these allocations, it is a good choice for the EFI RNG seed, as the allocation is guaranteed to survive kexec reboots. One additional reason for changing this now is to align it with the upcoming recommendation for EFI bootloader provided RNG seeds, which must not use EFI runtime services code/data allocations.

As part of a useful rework of the use of this region, 32edc40ae65c ("ieee802154: change _cb handling slightly") introduced mac_cb_init() to basically memset the cb field to 0. In particular, this new function got called at the beginning of mac802154_parse_frame_start(), right before the location where the buffer got actually filled. What went through unnoticed however, is the fact that the very first helper called by device drivers in the receive path already used this area to save the LQI value for later extraction. Resetting the cb field "so late" led to systematically zeroing the LQI. If we consider the reset of the cb field needed, we can make it as soon as we get an skb from a device driver, right before storing the LQI, as is the very first time we need to write something there.

Both of these methods has pre-requisite requirement to keep GFX PCI endpoint in D0 for a supported iomem transaction over PCI link. (Refer PCIe specs 5.3.1.4.1) Both DG1/DG2 have a known hardware bug that violates the PCIe specs and support the iomem read write transaction over PCIe bus despite endpoint is D3 state. Due to above H/W bug, we had never observed any issue with i915 runtime PM versus lmem access. But this issue becomes visible when PCIe gfx endpoint's upstream bridge enters to D3, at this point any lmem read/write access will be returned as unsupported request. But again this issue is not observed on every platform because it has been observed on few host machines DG1/DG2 endpoint's upstream bridge does not bind with pcieport driver. which really disables the PCIe power savings and leaves the bridge at D0 state. We need a unique interface to read/write from lmem with runtime PM wakeref protection something similar to intel_uncore_{read, write}, keep autosuspend control to 'on' on all discrete platforms, until we have a unique interface to read/write from lmem. This just change the default autosuspend setting of i915 on dGPU, user can still change it to 'auto'. v2: - Modified the commit message and subject with more information. - Changed the Fixes tag to LMEM support commit.

However, if CONFIG_MACSEC is set, rtnl_lock is acquired both from aq_nic_service_task and aq_linkstate_threaded_isr. Then a deadlock happens if aq_nic_stop tries to cancel/disable them when they've already started their execution. As the deadlock is caused by rtnl_lock, it causes many other processes to stall, not only atlantic related stuff. Fix it by introducing a mutex that protects each NIC's macsec related data, and locking it instead of the rtnl_lock from the service task and the threaded IRQ. Before this patch, all macsec data was protected with rtnl_lock, but maybe not all of it needs to be protected. With this new mutex, further efforts can be made to limit the protected data only to that which requires it. However, probably it doesn't worth it because all macsec's data accesses are infrequent, and almost all are done from macsec_ops or ethtool callbacks, called holding rtnl_lock, so macsec_mutex won't never be much contended. The issue appeared repeteadly attaching and deattaching the NIC to a bond interface. Doing that after this patch I cannot reproduce the bug.

Before introducing the cause of the problem, two hardware internal concepts need to be introduced: 1. Execution queue: The queue of hardware execution instructions, function reset and local invalidate are queued for execution in this queue. 2.Local queue: A queue that stores local operation instructions. The instructions in the local queue will be sent to the execution queue for execution. The instructions in the local queue will not be removed until the execution is completed. The reason for the problem is as follows: 1. There is a function reset instruction in the execution queue, which is currently being executed. A necessary condition for the successful execution of function reset is: the hardware pipeline needs to empty the instructions that were not completed before; 2. A local invalidate instruction at the head of the local queue is sent to the execution queue. Now there are two instructions in the execution queue, the first is the function reset instruction, and the second is the local invalidate instruction, which will be executed in se quence; 3. The user has issued many local invalidate operations, causing the local queue to be filled up. 4. The user still has a new local operation command and is queuing to enter the local queue. But the local queue is full and cannot receive new instructions, this instruction is temporarily stored at the hardware pipeline. 5. The function reset has been waiting for the instruction before the hardware pipeline stage is drained. The hardware pipeline stage also caches a local invalidate instruction, so the function reset cannot be completed, and the instructions after it cannot be executed. These factors together cause the execution logic deadlock of the hardware, and the consequence is that RoCEE will not have any response. Considering that the local operation command may potentially cause RoCEE to hang, this feature is no longer supported.

'n' here is the number of items in this block, which in this case was 1, but we had 2 REMOVE_WHILE_FREEING operations. The actual root cause of this was that we were replaying operations for a block that shouldn't have been replayed. Consider the following sequence of events 1. We have an already modified root, and we do a btrfs_get_tree_mod_seq(). 2. We begin removing items from this root, triggering KEY_REPLACE for it's child slots. 3. We remove one of the 2 children this root node points to, thus triggering the root node promotion of the remaining child, and freeing this node. 4. We modify a new root, and re-allocate the above node to the root node of this other root. The tree mod log looks something like this logical 0 op KEY_REPLACE (slot 1) seq 2 logical 0 op KEY_REMOVE (slot 1) seq 3 logical 0 op KEY_REMOVE_WHILE_FREEING (slot 0) seq 4 logical 4096 op LOG_ROOT_REPLACE (old logical 0) seq 5 logical 8192 op KEY_REMOVE_WHILE_FREEING (slot 1) seq 6 logical 8192 op KEY_REMOVE_WHILE_FREEING (slot 0) seq 7 logical 0 op LOG_ROOT_REPLACE (old logical 8192) seq 8 >From here the bug is triggered by the following steps 1. Call btrfs_get_old_root() on the new_root. 2. We call tree_mod_log_oldest_root(btrfs_root_node(new_root)), which is currently logical 0. 3. tree_mod_log_oldest_root() calls tree_mod_log_search_oldest(), which gives us the KEY_REPLACE seq 2, and since that's not a LOG_ROOT_REPLACE we incorrectly believe that we don't have an old root, because we expect that the most recent change should be a LOG_ROOT_REPLACE. 4. Back in tree_mod_log_oldest_root() we don't have a LOG_ROOT_REPLACE, so we don't set old_root, we simply use our existing extent buffer. 5. Since we're using our existing extent buffer (logical 0) we call tree_mod_log_search(0) in order to get the newest change to start the rewind from, which ends up being the LOG_ROOT_REPLACE at seq 8. 6. Again since we didn't find an old_root we simply clone logical 0 at it's current state. 7. We call tree_mod_log_rewind() with the cloned extent buffer. 8. Set n = btrfs_header_nritems(logical 0), which would be whatever the original nritems was when we COWed the original root, say for this example it's 2. 9. We start from the newest operation and work our way forward, so we see LOG_ROOT_REPLACE which we ignore. 10. Next we see KEY_REMOVE_WHILE_FREEING for slot 0, which triggers the BUG_ON(tm->slot < n), because it expects if we've done this we have a completely empty extent buffer to replay completely. The correct thing would be to find the first LOG_ROOT_REPLACE, and then get the old_root set to logical 8192. In fact making that change fixes this particular problem. However consider the much more complicated case. We have a child node in this tree and the above situation. In the above case we freed one of the child blocks at the seq 3 operation. If this block was also re-allocated and got new tree mod log operations we would have a different problem. btrfs_search_old_slot(orig root) would get down to the logical 0 root that still pointed at that node. However in btrfs_search_old_slot() we call tree_mod_log_rewind(buf) directly. This is not context aware enough to know which operations we should be replaying. If the block was re-allocated multiple times we may only want to replay a range of operations, and determining what that range is isn't possible to determine. We could maybe solve this by keeping track of which root the node belonged to at every tree mod log operation, and then passing this around to make sure we're only replaying operations that relate to the root we're trying to rewind. However there's a simpler way to solve this problem, simply disallow reallocations if we have currently running tree mod log users. We already do this for leaf's, so we're simply expanding this to nodes as well. This is a relatively uncommon occurrence, and the problem is complicated enough I'm worried that we will still have corner cases in the reallocation case. So fix this in the most straightforward way possible.

However, there's still a bug causing the corner subcase fails with a ENOENT error. Here's shortened steps of that subcase: $ btrfs subvolume create vol $ touch vol/foo $ btrfs subvolume snapshot -r vol snap1 $ btrfs subvolume snapshot -r vol snap2 # Turn the second snapshot to RW mode and delete the file while # holding an open file descriptor on it $ btrfs property set snap2 ro false $ exec 73 /dev/null At subvol snap1 ERROR: send ioctl failed with -2: No such file or directory It's subcase 3 of BTRFS_COMPARE_TREE_CHANGED in the commit 9ed0a72e5b35 ("btrfs: send: fix failures when processing inodes with no links"). And it's not a common case. We still have not met it in the real world. Theoretically, this case can happen in a batch cascading snapshot backup. In cascading backups, the receive operation in the middle may cause orphan inodes to appear because of the open file descriptors on the snapshot files during receiving. And if we don't do the batch snapshot backups in their creation order, then we can have an inode, which is an orphan in the parent snapshot but refers to a file in the send snapshot. Since an orphan inode has no paths, the send operation will fail with a ENOENT error if it tries to generate a path for it. In that patch, this subcase will be treated as an inode with a new generation. However, when the routine tries to delete the old paths in the parent snapshot, the function process_all_refs() doesn't check whether there are paths recorded or not before it calls the function process_recorded_refs(). And the function process_recorded_refs() try to get the first path in the parent snapshot in the beginning. Since it has no paths in the parent snapshot, the send operation fails. To fix this, we can easily put a link count check to avoid entering the deletion routine like what we do a link count check to avoid creating a new one. Moreover, we can assume that the function process_all_refs() can always collect references to process because we know it has a positive link count.

The bug is that when we're in fast recovery in a scenario with SACK reneging, every time we get an ACK we call tcp_check_sack_reneging() and it can note the apparent SACK reneging and rearm the RTO timer for srtt/2 into the future. In some SACK reneging scenarios that can happen repeatedly until the receive window fills up, at which point the sender can't send any more, the ACKs stop arriving, and the RTO fires at srtt/2 after the last ACK. But that can take far too long (O(10 secs)), since the connection is stuck in fast recovery with a low cwnd that cannot grow beyond ssthresh, even if more bandwidth is available. This fix changes the logic in tcp_check_sack_reneging() to only rearm the RTO timer if data is cumulatively ACKed, indicating forward progress. This avoids this kind of nearly infinite loop of RTO timer re-arming. In addition, this meets the goals of tcp_check_sack_reneging() in handling Windows TCP behavior that looks temporarily like SACK reneging but is not really. Many thanks to Jakub Kicinski and Neil Spring, who reported this issue and provided critical packet traces that enabled root-causing this issue. Also, many thanks to Jakub Kicinski for testing this fix.

Even tho we previously dropped the first packet received when over memory limit - the consecutive ones would get thru by using the cache. The charging was happening in batches of 128kB, so we'd let in 128kB (truesize) worth of packets per one drop. After the change we no longer force charge, there will be no cache filling side effects. This causes significant drops and connection stalls for workloads which use a lot of page cache, since we can't reclaim page cache under GFP_NOWAIT. Some of the latency can be recovered by improving SACK reneg handling but nowhere near enough to get back to the pre-5.15 performance (the application I'm experimenting with still sees 5-10x worst latency). Apply the suggested workaround of using GFP_ATOMIC. We will now be more permissive than previously as we'll drop _no_ packets in softirq when under pressure. But I can't think of any good and simple way to address that within networking.

This becomes tedious as we move to more strict validation. Families must define reject all policies if they don't want any attributes accepted. Piggy back on the resv_start_op field as the switchover point. AFAICT only ethtool has added new commands since the resv_start_op was defined, and it has per-op policies so this should be a no-op.

Once the HW finish with this frame, it would generate an interrupt and then the dcb can be reused and memory can be freed. For each dcb there is an dcb buf that contains some meta-data(is used by PTP, is it free). There is 1 to 1 relationship between dcb and dcb_buf. The following issue was observed. That sometimes after changing the MTU to allocate new tx dcbs and dcbs_buf, two frames were not transmitted. The frames were not transmitted because when reloading the tx dcbs, it was always presuming to use the first dcb but that was not always happening. Because it could be that the last tx dcb used before changing MTU was first dcb and then when it tried to get the next dcb it would take dcb 1 instead of 0. Because it is supposed to take a different dcb than the last used one. This can be fixed simply by changing tx->last_in_use to -1 when the fdma is disabled to reload the new dcb and dcbs_buff. But there could be a different issue. For example, right after the frame is sent, the MTU is changed. Now all the dcbs and dcbs_buf will be cleared. And now get the interrupt from HW that it finished with the frame. So when we try to clear the skb, it is not possible because we lost all the dcbs_buf. The solution here is to stop replacing the tx dcbs and dcbs_buf when changing MTU because the TX doesn't care what is the MTU size, it is only the RX that needs this information.

For passive sockets, we initialize such address at accept() time. Depending on the running configuration and the user-space timing, a passive MPJ subflow can join the msk socket before accept() completes. In such case, the PM assigns a wrong local id to the MPJ subflow and later PM netlink operations will end-up touching the wrong/unexpected subflow. All the above causes sporadic self-tests failures, especially when the host is heavy loaded.

Refactor such implementation to use the common helper, moving the MPTCP-specific bits into mptcp_connect(). Additionally, avoid an indirect call to the subflow connect callback. Note that the fastopen call-path invokes mptcp_connect() while already holding the subflow socket lock. Explicitly keep track of such path via a new MPTCP-level flag and handle the locking accordingly.

This will cause divide-by-zero errors at btrfs_rmap_block, which is introduced by a recent kernel patch ac0677348f3c ("btrfs: merge calculations for simple striped profiles in btrfs_rmap_block"): if (map->type & (BTRFS_BLOCK_GROUP_RAID0 | BTRFS_BLOCK_GROUP_RAID10)) { stripe_nr = stripe_nr * map->num_stripes + i; stripe_nr = div_u64(stripe_nr, map->sub_stripes); <<< } [CAUSE] From the more recent report, it has been proven that we have some chunks with 0 as sub_stripes, mostly caused by older mkfs. It turns out that the mkfs.btrfs fix is only introduced in 6718ab4d33aa ("btrfs-progs: Initialize sub_stripes to 1 in btrfs_alloc_data_chunk") which is included in v5.4 btrfs-progs release. So there would be quite some old filesystems with such 0 sub_stripes. [FIX] Just don't trust the sub_stripes values from disk. We have a trusted btrfs_raid_array[] to fetch the correct sub_stripes numbers for each profile and that are fixed. By this, we can keep the compatibility with older filesystems while still avoid divide-by-zero bugs.

This is problematic, for example, on hybrid platforms where MSR_TURBO_RATIO_LIMIT for P-cores and E-cores is different, so the values read from it on a P-core are generally not applicable to E-cores and the other way around. For this reason, make the driver access all MSRs on the target CPU on platforms using the "core" pstate_funcs callbacks which is the case for all of the hybrid platforms released to date. For this purpose, pass a CPU argument to the ->get_max(), ->get_max_physical(), ->get_min() and ->get_turbo() pstate_funcs callbacks and from there pass it to rdmsrl_on_cpu() or rdmsrl_safe_on_cpu() to access the MSR on the target CPU.

Wysocki" Date: Mon, 24 Oct 2022 21:22:48 +0200 Subject: cpufreq: intel_pstate: hybrid: Use known scaling factor for P-cores Commit 46573fd6369f ("cpufreq: intel_pstate: hybrid: Rework HWP calibration") attempted to use the information from CPPC (the nominal performance in particular) to obtain the scaling factor allowing the frequency to be computed if the HWP performance level of the given CPU is known or vice versa. However, it turns out that on some platforms this doesn't work, because the CPPC information on them does not align with the contents of the MSR_HWP_CAPABILITIES registers. This basically means that the only way to make intel_pstate work on all of the hybrid platforms to date is to use the observation that on all of them the scaling factor between the HWP performance levels and frequency for P-cores is 78741 (approximately 100000/1.27). For E-cores it is 100000, which is the same as for all of the non-hybrid "core" platforms and does not require any changes. Accordingly, make intel_pstate use 78741 as the scaling factor between HWP performance levels and frequency for P-cores on all hybrid platforms and drop the dependency of the HWP calibration code on CPPC.

When that happens during memory pressure, there is a need to reclaim memory, which in turn may ask the nvme-tcp device to write out dirty pages, however this is not possible due to a ctrl teardown that is going on. Set PF_MEMALLOC to the task that releases the socket to grant access to PF_MEMALLOC reserves. In addition, do the same for the nvme-tcp thread as this may also originate from the swap itself and should be more resilient to memory pressure situations.

This is seen with self-powered usb devices that survive in U3 link suspended state over S5. A more generic solution to power off ports at shutdown was attempted in commit 83810f84ecf1 ("xhci: turn off port power in shutdown") but it caused regression. Add host specific XHCI_RESET_TO_DEFAULT quirk which will reset host and ports back to default state in shutdown.

Historically this is accomplished by a long list of PCIe IDs that correspond to these endpoints because the xhci_hcd driver will not default to allowing runtime PM for all devices. As both AMD and Intel have released new products with new XHCI controllers this list continues to grow. In reviewing the XHCI specification v1.2 on page 607 there is already a requirement that the PCI power management states D3hot and D3cold must be supported. In the quirk list, use this to indicate that runtime PM should be allowed on XHCI controllers. The following controllers are known to be xHC 1.2 and dropped explicitly: * AMD Yellow Carp * Intel Alder Lake * Intel Meteor Lake * Intel Raptor Lake [keep PCI ID for Alder Lake PCH for recently added quirk -Mathias] Cc: stable@vger.kernel.org Suggested-by: Mathias Nyman Link: https://www.intel.com/content/dam/www/public/us/en/documents/technical-specifications/extensible-host-controler-interface-usb-xhci.pdf Signed-off-by: Mario Limonciello Reviewed-by: Mika Westerberg Signed-off-by: Mathias Nyman Link: https://lore.kernel.org/r/20221024142720.4122053-4-mathias.nyman@intel.com Signed-off-by: Greg Kroah-Hartman --- drivers/usb/host/xhci-pci.c | 32 ++++---------------------------- 1 file changed, 4 insertions(+), 28 deletions(-) diff --git a/drivers/usb/host/xhci-pci.c b/drivers/usb/host/xhci-pci.c index fbbd547ba12a..7bccbe50bab1 100644 --- a/drivers/usb/host/xhci-pci.c +++ b/drivers/usb/host/xhci-pci.c @@ -58,25 +58,13 @@ #define PCI_DEVICE_ID_INTEL_CML_XHCI 0xa3af #define PCI_DEVICE_ID_INTEL_TIGER_LAKE_XHCI 0x9a13 #define PCI_DEVICE_ID_INTEL_MAPLE_RIDGE_XHCI 0x1138 -#define PCI_DEVICE_ID_INTEL_ALDER_LAKE_XHCI 0x461e -#define PCI_DEVICE_ID_INTEL_ALDER_LAKE_N_XHCI 0x464e -#define PCI_DEVICE_ID_INTEL_ALDER_LAKE_PCH_XHCI 0x51ed -#define PCI_DEVICE_ID_INTEL_RAPTOR_LAKE_XHCI 0xa71e -#define PCI_DEVICE_ID_INTEL_METEOR_LAKE_XHCI 0x7ec0 +#define PCI_DEVICE_ID_INTEL_ALDER_LAKE_PCH_XHCI 0x51ed #define PCI_DEVICE_ID_AMD_RENOIR_XHCI 0x1639 #define PCI_DEVICE_ID_AMD_PROMONTORYA_4 0x43b9 #define PCI_DEVICE_ID_AMD_PROMONTORYA_3 0x43ba #define PCI_DEVICE_ID_AMD_PROMONTORYA_2 0x43bb #define PCI_DEVICE_ID_AMD_PROMONTORYA_1 0x43bc -#define PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_1 0x161a -#define PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_2 0x161b -#define PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_3 0x161d -#define PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_4 0x161e -#define PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_5 0x15d6 -#define PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_6 0x15d7 -#define PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_7 0x161c -#define PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_8 0x161f #define PCI_DEVICE_ID_ASMEDIA_1042_XHCI 0x1042 #define PCI_DEVICE_ID_ASMEDIA_1042A_XHCI 0x1142 @@ -272,12 +260,7 @@ static void xhci_pci_quirks(struct device *dev, struct xhci_hcd *xhci) pdev->device == PCI_DEVICE_ID_INTEL_TITAN_RIDGE_DD_XHCI || pdev->device == PCI_DEVICE_ID_INTEL_ICE_LAKE_XHCI || pdev->device == PCI_DEVICE_ID_INTEL_TIGER_LAKE_XHCI || - pdev->device == PCI_DEVICE_ID_INTEL_MAPLE_RIDGE_XHCI || - pdev->device == PCI_DEVICE_ID_INTEL_ALDER_LAKE_XHCI || - pdev->device == PCI_DEVICE_ID_INTEL_ALDER_LAKE_N_XHCI || - pdev->device == PCI_DEVICE_ID_INTEL_ALDER_LAKE_PCH_XHCI || - pdev->device == PCI_DEVICE_ID_INTEL_RAPTOR_LAKE_XHCI || - pdev->device == PCI_DEVICE_ID_INTEL_METEOR_LAKE_XHCI)) + pdev->device == PCI_DEVICE_ID_INTEL_MAPLE_RIDGE_XHCI)) xhci->quirks |= XHCI_DEFAULT_PM_RUNTIME_ALLOW; if (pdev->vendor == PCI_VENDOR_ID_ETRON && @@ -346,15 +329,8 @@ static void xhci_pci_quirks(struct device *dev, struct xhci_hcd *xhci) pdev->device == PCI_DEVICE_ID_AMD_PROMONTORYA_4)) xhci->quirks |= XHCI_NO_SOFT_RETRY; - if (pdev->vendor == PCI_VENDOR_ID_AMD && - (pdev->device == PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_1 || - pdev->device == PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_2 || - pdev->device == PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_3 || - pdev->device == PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_4 || - pdev->device == PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_5 || - pdev->device == PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_6 || - pdev->device == PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_7 || - pdev->device == PCI_DEVICE_ID_AMD_YELLOW_CARP_XHCI_8)) + /* xHC spec requires PCI devices to support D3hot and D3cold */ + if (xhci->hci_version >= 0x120) xhci->quirks |= XHCI_DEFAULT_PM_RUNTIME_ALLOW; if (xhci->quirks & XHCI_RESET_ON_RESUME) -- cgit v1.2.3 From 5aed5b7c2430ce318a8e62f752f181e66f0d1053 Mon Sep 17 00:00:00 2001 From: Mathias Nyman Date: Mon, 24 Oct 2022 17:27:20 +0300 Subject: xhci: Remove device endpoints from bandwidth list when freeing the device MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Endpoints are normally deleted from the bandwidth list when they are dropped, before the virt device is freed.

This is a stop gap hack till we do like tools/bpf does with bpftool, i.e. bootstrap the libbpf build and install it in the perf build directory when not using 'make LIBBPF_DYNAMIC=1'. That has to be done to all libraries in tools/lib/, so tha we can remove -Itools/lib/ from the tools/perf CFLAGS. Noticed when building with LIBBPF_DYNAMIC=1 and libbpf 0.7.0 on RHEL9.

But when build with LIBBPF_DYNAMIC=1 we now need to check if that function is available so that perf can build with older libbpf versions, even if the end result is emitting a warning to the user that the use of the perf BPF loader requires a newer libbpf, since bpf_program__set_insns() touches libbpf objects internal state. This affects only 'perf trace' when using bpf C code or pre-compiled bytecode as an event. Noticed on RHEL9, that has libbpf 0.7.0, where bpf_program__set_insns() isn't available.

The PMU device driver exports the counters via sysfs files listed in directory /sys/devices/pai_crypto. To specify an event from that PMU, use 'perf stat -e pai_crypto/XXX/'. However the JSON file mentioned in above commit exports the counter decriptions in file pmu-events/arch/s390/cf_z16/pai.json. Rename this file to pmu-events/arch/s390/cf_z16/pai_crypto.json to make the naming consistent. Now 'perf list' shows the counter names under pai_crypto section: pai_crypto: CRYPTO_ALL [CRYPTO ALL. Unit: pai_crypto] ... Output before was pai: CRYPTO_ALL [CRYPTO ALL. Unit: pai_crypto] ...

The newly added check for online devices incorrectly assumes that an I/O-subchannel's drvdata points to a struct io_subchannel_private. For devices that are bound to a non-default I/O subchannel driver, such as the vfio_ccw driver, this results in an out-of-bounds read access during each scan. Fix this by changing the scan logic to rely on a driver-independent online indication. For this we can use struct subchannel->config.ena, which is the driver's requested subchannel-enabled state. Since I/Os can only be started on enabled subchannels, this matches the intent of the original optimization of not scanning devices where I/O might be running.

This change clears HARD_DIS without affecting other bits in the mask. When an interrupt hits in a soft-masked section that has MSR[EE]=1, it can hard disable and set PACA_IRQS_HARD_DIS, which must be cleared when returning to the EE=1 caller (unless it was set due to a MUST_HARD_MASK interrupt becoming pending). Failure to clear this leaves the returned-to context running with MSR[EE]=1 and PACA_IRQS_HARD_DIS, which confuses irq assertions and could be dangerous for code that might test the flag. This was observed in a hash MMU kernel where a kernel hash fault hits in a local_irqs_disabled region that has EE=1. The hash fault also runs with EE=1, then as it returns, a decrementer hits in the restart section and the irq restart code hard-masks which sets the PACA_IRQ_HARD_DIS flag, which is not clear when the original context is returned to.

However, it uses init_completion() to reinitialize the start_comp and stop_comp completions before sending the start/stop commands. In case the device sends the corresponding response just before the actual command is sent, complete() may be called concurrently with init_completion() which is not safe. This might be triggerable even with a properly functioning device by stopping the interface (CMD_STOP_CHIP) just after it goes bus-off (which also causes the driver to send CMD_STOP_CHIP when restart-ms is off), but that was not tested.

Conditions: The global receive IRQ line is shared between can0 and can1, either of the channels can trigger interrupt while the other channel's IRQ line is disabled (RFIE). When global a receive IRQ interrupt occurs, we mask the interrupt in the IRQ handler. Clearing and unmasking of the interrupt is happening in rx_poll(). There is a race condition where rx_poll() unmasks the interrupt, but the next IRQ handler does not mask the IRQ due to NAPIF_STATE_MISSED flag (e.g.: can0 RX FIFO interrupt is disabled and can1 is triggering RX interrupt, the delay in rx_poll() processing results in setting NAPIF_STATE_MISSED flag) leading to an IRQ storm. This patch fixes the issue by checking IRQ active and enabled before handling the IRQ on a particular channel.

KVM_REQ_TRIPLE_FAULT, when asserting that KVM didn't attempt to queue a new exception during event injection. KVM needs to emulate the injection itself when emulating Real Mode due to lack of unrestricted guest support (VMX) and will queue a triple fault if that emulation fails. Ideally the assertion would more precisely filter out the emulated Real Mode triple fault case, but rmode.vm86_active is buried in vcpu_vmx and can't be queried without a new kvm_x86_ops. And unlike "regular" exceptions, triple fault cannot put the vCPU into an infinite loop; the triple fault will force either an exit to userspace or a nested VM-Exit, and triple fault after nested VM-Exit will force an exit to userspace. I.e. there is no functional issue, so just suppress the warning for triple faults. Opportunistically convert the warning to a one-time thing, when it fires, it fires _a lot_, and is usually user triggerable, i.e. can be used to spam the kernel log.

When KVM is loaded, adjust_vmx_controls checks that the bit is available before enabling the feature; however, other parts of the code check enable_sgx and not clearing the variable caused two different bugs, mostly affecting nested virtualization scenarios. First, because enable_sgx remained true, SECONDARY_EXEC_ENCLS_EXITING would be marked available in the capability MSR that are accessed by a nested hypervisor. KVM would then propagate the control from vmcs12 to vmcs02 even if it isn't supported by the processor, thus causing an unexpected VM-Fail (exit code 0x7) in L1. Second, vmx_set_cpu_caps() would not clear the SGX bits when hardware support is unavailable. This is a much less problematic bug as it only happens if SGX is soft-disabled (available in the processor but hidden in CPUID) or if SGX is supported for bare metal but not in the VMCS (will never happen when running on bare metal, but can theoertically happen when running in a VM). Last but not least, this ensures that module params in sysfs reflect KVM's actual configuration.

Initialize gfn_to_pfn_cache locks in dedicated helper Move the gfn_to_pfn_cache lock initialization to another helper and call the new helper during VM/vCPU creation. There are race conditions possible due to kvm_gfn_to_pfn_cache_init()'s ability to re-initialize the cache's locks. For example: a race between ioctl(KVM_XEN_HVM_EVTCHN_SEND) and kvm_gfn_to_pfn_cache_init() leads to a corrupted shinfo gpc lock. (thread 1) | (thread 2) | kvm_xen_set_evtchn_fast | read_lock_irqsave(&gpc->lock, ...) | | kvm_gfn_to_pfn_cache_init | rwlock_init(&gpc->lock) read_unlock_irqrestore(&gpc->lock, ...) | Rename "cache_init" and "cache_destroy" to activate+deactivate to avoid implying that the cache really is destroyed/freed. Note, there more races in the newly named kvm_gpc_activate() that will be addressed separately.

Not checking the active flag during refresh is particularly egregious, as KVM can end up with a valid, inactive cache, which can lead to a variety of use-after-free bugs, e.g. consuming a NULL kernel pointer or missing an mmu_notifier invalidation due to the cache not being on the list of gfns to invalidate. Note, "active" needs to be set if and only if the cache is on the list of caches, i.e. is reachable via mmu_notifier events. If a relevant mmu_notifier event occurs while the cache is "active" but not on the list, KVM will not acquire the cache's lock and so will not serailize the mmu_notifier event with active users and/or kvm_gpc_refresh(). A race between KVM_XEN_ATTR_TYPE_SHARED_INFO and KVM_XEN_HVM_EVTCHN_SEND can be exploited to trigger the bug. 1.

For example, when SA reaches , all subsequent packets get dropped with SA-icv-failure (integrity_failed). To reproduce the bug: - ConnectX-6 Dx with crypto enabled (FW 22.30.1004) - ipsec.conf: nic-offload = yes replay-window = 32 esn = yes salifetime=24h - Run netperf for a long time to send more than 2^32 packets netperf -H -t TCP_STREAM -l 20000 When 2^32 + replay_window packets are received, the replay window moves from the 2nd half of subspace (overlap=1) to the 1st half (overlap=0). The driver then updates the 'esn' value in NIC (i.e. seq_hi) as follows. seq_hi = xfrm_replay_seqhi(seq_bottom) new esn in NIC = seq_hi + 1 The +1 increment is wrong, as seq_hi already contains the correct seq_hi. For example, when seq_hi=1, the driver actually tells NIC to use seq_hi=2 (esn). This incorrect esn value causes all subsequent packets to fail integrity checks (SA-icv-failure). So, do not increment.

Before this patch, the below race between mlx5_cmd_cleanup_async_ctx and mlx5_cmd_exec_cb_handler was possible and lead to a use-after-free: 1. mlx5_cmd_cleanup_async_ctx is called while num_inflight is 2 (i.e. elevated by 1, a single inflight callback). 2. mlx5_cmd_cleanup_async_ctx decreases num_inflight to 1. 3. mlx5_cmd_exec_cb_handler is called, decreases num_inflight to 0 and is about to call wake_up(). 4. mlx5_cmd_cleanup_async_ctx calls wait_event, which returns immediately as the condition (num_inflight == 0) holds. 5. mlx5_cmd_cleanup_async_ctx returns. 6. The caller of mlx5_cmd_cleanup_async_ctx frees the mlx5_async_ctx object. 7. mlx5_cmd_exec_cb_handler goes on and calls wake_up() on the freed object. Fix it by syncing using a completion object. Mark it completed when num_inflight reaches 0.

An extreme case of memory pressure will result in exactly zero buffers being allocated for the RX ring, and in such a case it is expected that hardware drops all RX packets due to lack of buffers. This does not happen, because the reset-default value of the consumer and produces index is 0, and this makes the ENETC think that all buffers have been initialized and that it owns them (when in reality none were). The hardware guide explains this best: | Configure the receive ring producer index register RBaPIR with a value | of 0. The producer index is initially configured by software but owned | by hardware after the ring has been enabled. Hardware increments the | index when a frame is received which may consume one or more BDs. | Hardware is not allowed to increment the producer index to match the | consumer index since it is used to indicate an empty condition. The ring | can hold at most RBLENR[LENGTH]-1 received BDs. | | Configure the receive ring consumer index register RBaCIR. The | consumer index is owned by software and updated during operation of the | of the BD ring by software, to indicate that any receive data occupied | in the BD has been processed and it has been prepared for new data. | - If consumer index and producer index are initialized to the same | value, it indicates that all BDs in the ring have been prepared and | hardware owns all of the entries. | - If consumer index is initialized to producer index plus N, it would | indicate N BDs have been prepared. Note that hardware cannot start if | only a single buffer is prepared due to the restrictions described in | (2). | - Software may write consumer index to match producer index anytime | while the ring is operational to indicate all received BDs prior have | been processed and new BDs prepared for hardware. Normally, the value of rx_ring->rcir (consumer index) is brought in sync with the rx_ring->next_to_use software index, but this only happens if page allocation ever succeeded. When PI==CI==0, the hardware appears to receive frames and write them to DMA address 0x0 (?!), then set the READY bit in the BD. The enetc_clean_rx_ring() function (and its XDP derivative) is naturally not prepared to handle such a condition. It will attempt to process those frames using the rx_swbd structure associated with index i of the RX ring, but that structure is not fully initialized (enetc_new_page() does all of that). So what happens next is undefined behavior. To operate using no buffer, we must initialize the CI to PI + 1, which will block the hardware from advancing the CI any further, and drop everything. The issue was seen while adding support for zero-copy AF_XDP sockets, where buffer memory comes from user space, which can even decide to supply no buffers at all (example: "xdpsock --txonly"). However, the bug is present also with the network stack code, even though it would take a very determined person to trigger a page allocation failure at the perfect time (a series of ifup/ifdown under memory pressure should eventually reproduce it given enough retries).

In this case, the client doesn't handle the OLD_STATEID error from the server and will lose this lock, emitting: "NFS: nfs4_handle_delegation_recall_error: unhandled error -10024". Fix this by sending the task through the nfs4 error handling in nfs4_lock_done() when we may have to reconcile our stateid with what the server believes it to be. For this case, the result is a retry of the LOCK operation with the updated stateid.

Since it's a fairly common situation, let's just remove the WARN_ON but keep the check that prevents us from dereferencing the pointer. Interestingly, it fixes a regression on the Mediatek MT8195 where the GPU would stall during a clk_set_rate for its main clock. We couldn't come up with a proper explanation since the condition is essentially the same. It was then assumed that it could be timing related since printing the warning stacktrace takes a while, but we couldn't replicate the failure by using fairly large (10ms) mdelays.

To update the backup superblocks, the online resize uses the function update_backups() in fs/ext4/resize.c. This function was not updating the checksum field in the backup superblocks. This wasn't a big deal previously, because e2fsck didn't care about the checksum field in the backup superblock. (And indeed, update_backups() goes all the way back to the ext3 days, well before we had support for metadata checksums.) However, there is an alternate, more general way of updating superblock fields, ext4_update_primary_sb() in fs/ext4/ioctl.c. This function does check the checksum of the backup superblock, and if it doesn't match will mark the file system as corrupted. That was clearly not the intent, so avoid to aborting the resize when a bad superblock is found. In addition, teach update_backups() to properly update the checksum in the backup superblocks. We will eventually want to unify updapte_backups() with the infrasture in ext4_update_primary_sb(), but that's for another day. Note: The problem has been around for a while; it just didn't really matter until ext4_update_primary_sb() was added by commit bbc605cdb1e1 ("ext4: implement support for get/set fs label"). And it became trivially easy to reproduce after commit 827891a38acc ("ext4: update the s_overhead_clusters in the backup sb's when resizing") in v6.0.

There are two reasons for memleak in dsa_loop_init(). First, fixed_phy_register() create and register phy_device: fixed_phy_register() get_phy_device() phy_device_create() # freed by phy_device_free() phy_device_register() # freed by phy_device_remove() But fixed_phy_unregister() only calls phy_device_remove(). So the memory allocated in phy_device_create() is leaked. Second, when mdio_driver_register() fail in dsa_loop_init(), it just returns and there is no cleanup for phydevs. Fix the problems by catching the error of mdio_driver_register() in dsa_loop_init(), then calling both fixed_phy_unregister() and phy_device_free() to release phydevs. Also add a function for phydevs cleanup to avoid duplacate.

For the timer injection testcase (#22), re-arm the timer until the IRQ is successfully injected. If the timer expires while the shared info is deactivated (invalid), KVM will drop the event.

Relying on the compiler thinking that the flag is global and thus might change also works, but it's subtle, less robust, and looks like a bug at first glance, e.g. risks being "fixed" and breaking the test. Make the flag "static" as well since convincing the compiler it's global is no longer necessary. Alternatively, the flag could be accessed with {READ,WRITE}_ONCE(), but literally every access would need the wrappers, and eking out performance isn't exactly top priority for selftests.

Unfortunately, there is another case to consider here, which was missed: if the efivars layer is backed by the EFI runtime services as usual, but the EFI implementation predates the introduction of QueryVariableInfo(), we will return EFI_UNSUPPORTED, and this is no longer being dealt with correctly. So let's fix this, and while at it, clean up the code a bit, by merging the check_var_size() routines as well as their callers.

This patchset fixes 3 regressions introduced by the recent readahead code changes. The first regression is causing "snaps" to randomly fail after a couple of hours or days, which how the regression came to light. This patch (of 3): If a file isn't a whole multiple of the page size, the last page will have trailing bytes unfilled. There was a mistake in the readahead code which did this. In particular it incorrectly assumed that the last page in the readahead page array (page[nr_pages - 1]) will always contain the last page in the block, which if we're at file end, will be the page that needs to be zero filled. But the readahead code may not return the last page in the block, which means it is unmapped and will be skipped by the decompressors (a temporary buffer used). In this case the zero filling code will zero out the wrong page, leading to data corruption. Fix this by by extending the "page actor" to return the last page if present, or NULL if a temporary buffer was used.

For example, in my system, $ cat /sys/devices/system/node/node0/cpumap f,ffffffff $ cat /sys/devices/system/cpu/cpu2/topology/core_cpus 0,00100004 $ cat cat /sys/devices/system/node/node0/cpulist 0-35 $ cat /sys/devices/system/cpu/cpu2/topology/core_cpus_list 2,20 It looks reasonable to use "nodemap" for node mask and "nodelist" for node list.

That malloc library may be doing MADV_DONTNEED calls on memory that is no longer needed, expecting those calls to happen on PAGE_SIZE boundaries. However, currently the MADV_DONTNEED code rounds up any such requests to HPAGE_PMD_SIZE boundaries. This leads to undesired outcomes when jemalloc expects a 4kB MADV_DONTNEED, but 2MB of memory get zeroed out, instead. Use of pre-built shared libraries means that user code does not always know the page size of every memory arena in use. Avoid unexpected data loss with MADV_DONTNEED by rounding up only to PAGE_SIZE (in do_madvise), and rounding down to huge page granularity. That way programs will only get as much memory zeroed out as they requested.

But now commit 71e2d666ef85 ("mm/huge_memory: do not clobber swp_entry_t during THP split") issues a warning when page_tail->private is found to be non-0 (unless it's swapcache). Change that warning to dump page_tail (which also dumps head), instead of just the head: so far we have seen dead000000000122, dead000000000003, dead000000000001 or 0000000000000002 in the raw output for tail private. We could just delete the warning, but today's consensus appears to want page->private to be 0, unless there's a good reason for it to be set: so now clear it in prep_compound_tail() (more general than just for THP; but not for high order allocation, which makes no pass down the tails).

Worse, when the function is called strlen(), the function is simply replaced with a jump to itself, hence becomes an infinite loop. One way to avoid this is to always set -ffreestanding, but the calling code doesn't know this and there's no way (either via attributes or pragmas) to globally enable it from include files, effectively leaving a painful situation for the caller. Alexey suggested to place an empty asm() statement inside the loop to stop gcc from recognizing a well-known pattern, which happens to work pretty fine. At least it allows us to make sure our local definition is not replaced with a self jump. The function only needs to be renamed back to strlen() so that the symbol exists, which implies that nolibc_strlen() which is used on variable strings has to be declared as a macro that points back to it before the strlen() macro is redifined. It was verified to produce valid code with gcc 3.4 to 12.1 at different optimization levels, and both with constant and variable strings. In case this problem surfaces again in the future, an alternate approach consisting in adding an optimize("no-tree-loop-distribute-patterns") function attribute for gcc>=12 worked as well but is less pretty.

If char happens to be unsigned, the casts are ok, but then obviously the c1 variable can never contain a negative value. And when char is signed, the casts are wrong, and there's still a problem with using an 8-bit quantity to hold the difference, because that can range from -255 to +255. For example, assuming char is signed, comparing two 1-byte buffers, one containing 0x00 and another 0x80, the current implementation would return -128 for both memcmp(a, b, 1) and memcmp(b, a, 1), whereas one of those should of course return something positive.

Indeed at that point the arm64 CPU features, which verify that all CPUs have compatible capabilities, are not finalized so arch_get_random_seed_longs() is unsuccessful. Instead random_init() should use the _early functions, which check only the boot CPU on arm64. On other architectures the _early functions directly call the normal ones.

This should be impossible, since the detection function will explicitly give up if the destination field size is unknown. For example, the JFS warning was: memcpy: detected field-spanning write (size 132) of single field "ip->i_link" at fs/jfs/namei.c:950 (size 18446744073709551615) Other cases of this warning (e.g.[3]) have reported correctly, and the reproducer only happens under GCC (at least 10.2 and 12.1), so this currently appears to be a GCC bug. Explicitly capturing the __builtin_object_size() results in const temporary variables fixes the report. For example, the JFS reproducer now correctly reports the field size (128): memcpy: detected field-spanning write (size 132) of single field "ip->i_link" at fs/jfs/namei.c:950 (size 128) Examination of the .text delta (which is otherwise identical), shows the literal value used in the report changing: - mov $0xffffffffffffffff,%rcx + mov $0x80,%ecx [1] https://lore.kernel.org/lkml/Y0zEzZwhOxTDcBTB@codemonkey.org.uk/ [2] https://syzkaller.appspot.com/bug?id=23d613df5259b977dac1696bec77f61a85890e3d [3] https://lore.kernel.org/all/202210110948.26b43120-yujie.liu@intel.com/ Cc: "Dr. David Alan Gilbert" Cc: llvm@lists.linux.dev Cc: linux-hardening@vger.kernel.org Signed-off-by: Kees Cook --- include/linux/fortify-string.h | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) diff --git a/include/linux/fortify-string.h b/include/linux/fortify-string.h index 4029fe368a4f..0f00a551939a 100644 --- a/include/linux/fortify-string.h +++ b/include/linux/fortify-string.h @@ -441,13 +441,18 @@ __FORTIFY_INLINE bool fortify_memcpy_chk(__kernel_size_t size, #define __fortify_memcpy_chk(p, q, size, p_size, q_size, \ p_size_field, q_size_field, op) ({ \ - size_t __fortify_size = (size_t)(size); \ - WARN_ONCE(fortify_memcpy_chk(__fortify_size, p_size, q_size, \ - p_size_field, q_size_field, #op), \ + const size_t __fortify_size = (size_t)(size); \ + const size_t __p_size = (p_size); \ + const size_t __q_size = (q_size); \ + const size_t __p_size_field = (p_size_field); \ + const size_t __q_size_field = (q_size_field); \ + WARN_ONCE(fortify_memcpy_chk(__fortify_size, __p_size, \ + __q_size, __p_size_field, \ + __q_size_field, #op), \ #op ": detected field-spanning write (size %zu) of single %s (size %zu)\n", \ __fortify_size, \ "field \"" #p "\" at " __FILE__ ":" __stringify(__LINE__), \ - p_size_field); \ + __p_size_field); \ __underlying_##op(p, q, __fortify_size); \ }) -- cgit v1.2.3 From 7354c9024f2835f6122ed9612e21ab379df050f9 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 27 Oct 2022 14:21:07 -0700 Subject: netlink: hide validation union fields from kdoc Mark the validation fields as private, users shouldn't set them directly and they are too complicated to explain in a more succinct way (there's already a long explanation in the comment above).

The kernel cannot currently call request_module(), because it has no way of constructing the modalias name of the tagging protocol driver ("dsa_tag-%d", where the number is one of DSA_TAG_PROTO_*_VALUE). The device tree only contains the string name of the tagging protocol ("ocelot-8021q"), and the only mapping between the string and the DSA_TAG_PROTO_OCELOT_8021Q_VALUE is present in tag_ocelot_8021q.ko. So this is a chicken-and-egg situation and dsa_core.ko has nothing based on which it can automatically request the insertion of the module. As a consequence, if CONFIG_NET_DSA_TAG_OCELOT_8021Q is built as module, the switch will forever defer probing. The long-term solution is to make DSA call request_module() somehow, but that probably needs some refactoring. What we can do to keep operating with existing device tree blobs is to cancel the attempt to change the tagging protocol with the one specified there, and to remain operating with the default one. Depending on the situation, the default protocol might still allow some functionality (in the case of ocelot, it does), and it's better to have that than to fail to probe.

The generic infrastructure calls this via the .dumb_create() driver operation and thus creates a buffer without an associated kmap. alloc_kmap only makes a difference on devices without an IOMMU, but when it is missing rockchip_gem_prime_vmap() fails and the framebuffer cannot be used. Detect the case where a buffer is being allocated for the framebuffer and ensure a kernel mapping is created in this case.

Unless the planes are explicitly disabled, the address of the last framebuffer is kept in the registers of the VOP2. When re-enabling the encoder after it has been disabled by the driver, the VOP2 will start and read the framebuffer that has been freed but is still pointed to by the register. The iommu will catch these read accesses and print errors. Explicitly disable the planes when the crtc is disabled to reset the registers.

Although the list is arguably provided to userspace in precedence order, userspace can pick something out-of-order (and thus break when it shouldn't), or simply only support a format that is unsupported (and thus think it can work, which results in the appearance of a hang as FB blits fail later on, instead of the initialization error you'd expect in this case). Add checks to filter the list of emulated formats to only those supported for conversion to the native format. This presumes that there is a single native format (only the first is checked, if there are multiple). Refactoring this API to drop the native list or support it properly (by returning the appropriate emulated->native mapping table) is left for a future patch. The simpledrm driver is left as-is with a full table of emulated formats. This keeps all currently working conversions available and drops all the broken ones (i.e. this a strict bugfix patch, adding no new supported formats nor removing any actually working ones). In order to avoid proliferation of emulated formats, future drivers should advertise only XRGB8888 as the sole emulated format (since some userspace assumes its presence). This fixes a real user regression where the ?RGB2101010 support commit started advertising it unconditionally where not supported, and KWin decided to start to use it over the native format and broke, but also the fixes the spurious RGB565/RGB888 formats which have been wrongly unconditionally advertised since the dawn of simpledrm.

charset=UTF-8 Content-Transfer-Encoding: 8bit swiotlb_max_segment used to return either the maximum size that swiotlb could bounce, or for Xen PV PAGE_SIZE even if swiotlb could bounce buffer larger mappings. This made i915 on Xen PV work as it bypasses the coherency aspect of the DMA API and can't cope with bounce buffering and this avoided bounce buffering for the Xen/PV case. So instead of adding this hack back, check for Xen/PV directly in i915 for the Xen case and otherwise use the proper DMA API helper to query the maximum mapping size. Replace swiotlb_max_segment() calls with dma_max_mapping_size(). In i915_gem_object_get_pages_internal() no longer consider max_segment only if CONFIG_SWIOTLB is enabled. There can be other (iommu related) causes of specific max segment sizes.

This is because we tell iomap to not call generic_write_sync(), which would result in calling btrfs_sync_file(), in order to avoid a deadlock since iomap can call it while we are holding the inode's lock and btrfs_sync_file() needs to acquire the inode's lock. The deadlock happens only if the write happens synchronously, when iomap_dio_rw() calls iomap_dio_complete() before it returns. Instead we do the sync ourselves at btrfs_do_write_iter(). For a nowait write however we can end up not doing the sync ourselves at at btrfs_do_write_iter() because the write could have been queued, and therefore we get -EIOCBQUEUED returned from iomap in such case. That makes us skip the sync call at btrfs_do_write_iter(), as we don't do it for any error returned from btrfs_direct_write(). We can't simply do the call even if -EIOCBQUEUED is returned, since that would block the task waiting for IO, both for the data since there are bios still in progress as well as potentially blocking when joining a log transaction and when syncing the log (writing log trees, super blocks, etc). So let iomap do the sync call itself and in order to avoid deadlocks for the case of synchronous writes (without nowait), use __iomap_dio_rw() and have ourselves call iomap_dio_complete() after unlocking the inode. A test case will later be sent for fstests, after this is fixed in Linus' tree.

Wong" Date: Thu, 20 Oct 2022 16:39:59 -0700 Subject: xfs: fix memcpy fortify errors in EFI log format copying Starting in 6.1, CONFIG_FORTIFY_SOURCE checks the length parameter of memcpy. Since we're already fixing problems with BUI item copying, we should fix it everything else. An extra difficulty here is that the ef[id]_extents arrays are declared as single-element arrays. This is not the convention for flex arrays in the modern kernel, and it causes all manner of problems with static checking tools, since they often cannot tell the difference between a single element array and a flex array. So for starters, change those array[1] declarations to array[] declarations to signal that they are proper flex arrays and adjust all the "size-1" expressions to fit the new declaration style. Next, refactor the xfs_efi_copy_format function to handle the copying of the head and the flex array members separately. While we're at it, fix a minor validation deficiency in the recovery function.

Wong" Date: Mon, 10 Oct 2022 11:33:47 -0700 Subject: xfs: check deferred refcount op continuation parameters If we're in the middle of a deferred refcount operation and decide to roll the transaction to avoid overflowing the transaction space, we need to check the new agbno/aglen parameters that we're about to record in the new intent. Specifically, we need to check that the new extent is completely within the filesystem, and that continuation does not put us into a different AG. If the keys of a node block are wrong, the lookup to resume an xfs_refcount_adjust_extents operation can put us into the wrong record block. If this happens, we might not find that we run out of aglen at an exact record boundary, which will cause the loop control to do the wrong thing. The previous patch should take care of that problem, but let's add this extra sanity check to stop corruption problems sooner than later. Signed-off-by: Darrick J.

Wong" Date: Mon, 10 Oct 2022 09:06:24 -0700 Subject: xfs: track cow/shared record domains explicitly in xfs_refcount_irec Just prior to committing the reflink code into upstream, the xfs maintainer at the time requested that I find a way to shard the refcount records into two domains -- one for records tracking shared extents, and a second for tracking CoW staging extents. The idea here was to minimize mount time CoW reclamation by pushing all the CoW records to the right edge of the keyspace, and it was accomplished by setting the upper bit in rc_startblock. We don't allow AGs to have more than 2^31 blocks, so the bit was free. Unfortunately, this was a very late addition to the codebase, so most of the refcount record processing code still treats rc_startblock as a u32 and pays no attention to whether or not the upper bit (the cow flag) is set. This is a weakness is theoretically exploitable, since we're not fully validating the incoming metadata records. Fuzzing demonstrates practical exploits of this weakness. If the cow flag of a node block key record is corrupted, a lookup operation can go to the wrong record block and start returning records from the wrong cow/shared domain. This causes the math to go all wrong (since cow domain is still implicit in the upper bit of rc_startblock) and we can crash the kernel by tricking xfs into jumping into a nonexistent AG and tripping over xfs_perag_get(mp, ) returning NULL. To fix this, start tracking the domain as an explicit part of struct xfs_refcount_irec, adjust all refcount functions to check the domain of a returned record, and alter the function definitions to accept them where necessary.

Wong" Date: Thu, 27 Oct 2022 09:48:59 -0700 Subject: xfs: fix agblocks check in the cow leftover recovery function As we've seen, refcount records use the upper bit of the rc_startblock field to ensure that all the refcount records are at the right side of the refcount btree. This works because an AG is never allowed to have more than (1U << 31) blocks in it. If we ever encounter a filesystem claiming to have that many blocks, we absolutely do not want reflink touching it at all. However, this test at the start of xfs_refcount_recover_cow_leftovers is slightly incorrect -- it /should/ be checking that agblocks isn't larger than the XFS_MAX_CRC_AG_BLOCKS constant, and it should check that the constant is never large enough to conflict with that CoW flag. Note that the V5 superblock verifier has not historically rejected filesystems where agblocks >= XFS_MAX_CRC_AG_BLOCKS, which is why this ended up in the COW recovery routine.

And skb->pfmemalloc is true, __kmalloc_reserve() would use pfmemalloc reserves without __GFP_NOWARN flag. Thus we got a warning as following: ======================================================== WARNING: CPU: 1 PID: 17965 at mm/page_alloc.c:5295 __alloc_pages+0x1308/0x16c4 mm/page_alloc.c:5295 ...

After ipv6_gso_pull_exthdrs() in ipv6_gro_receive(), network_header offset and transport_header offset are all bigger than U16_MAX. That would trigger skb->network_header and skb->transport_header overflow error, because they are all '__u16' type. Eventually, it would affect the value for __skb_push(skb, value), and make it be a big value. After __skb_push() in ipv6_gro_receive(), skb->data would less than skb->head, an out of bounds memory bug occurred. That would trigger the problem as following: ================================================================== BUG: KASAN: use-after-free in eth_type_trans+0x100/0x260 ...

For that to work with syscall wrappers, the prototype of the syscall must have the argument split so that the wrapper macro properly unpacks the arguments from pt_regs. The fanotify_mark() syscall is one such syscall, which already has a split prototype, guarded behind ARCH_SPLIT_ARG64. So select ARCH_SPLIT_ARG64 to get that prototype and fix fanotify_mark() on 32-bit kernels with syscall wrappers. Note also that fanotify_mark() is the only usage of ARCH_SPLIT_ARG64.

The SCMI core platform driver as it is now, instead, bails out reporting an error in case of an explicit unbind request. Fix the removal path by adding proper device links between the core SCMI device and the SCMI protocol devices so that a full SCMI stack unbind is triggered when the core driver is removed.

In fact the channel is owned by the SCMI platform until marked as free by the platform itself and, as such, cannot be used by the agent until relinquished. As a consequence a badly misbehaving SCMI platform firmware could lock the channel indefinitely and make the kernel side SCMI stack loop forever waiting for such channel to be freed, possibly hanging the whole boot sequence. Add a timeout to the existent Tx waiting spin-loop so that, when the system ends up in this situation, the SCMI stack can at least bail-out, nosily warn the user, and abort the transmission.

If cortex_a76_erratum_1463225_debug_handler() is probed, any debug exception or software breakpoint exception will result in recursive exceptions leading to a stack overflow. This can be triggered with the ftrace multiple_probes selftest, and as per the example splat below.

However, during cleanup of the region reference, a sanity check attempts to dereference the decoder, which in the above case didn't exist. This causes a NULL pointer dereference BUG. To fix this, refactor the decoder allocation and de-allocation into helper routines, and in this 'free' routine, check that the decoder, @cxld, is valid before attempting any operations on it.

Shutemov" Date: Fri, 28 Oct 2022 17:12:20 +0300 Subject: x86/tdx: Panic on bad configs that #VE on "private" memory access All normal kernel memory is "TDX private memory". This includes everything from kernel stacks to kernel text. Handling exceptions on arbitrary accesses to kernel memory is essentially impossible because they can happen in horribly nasty places like kernel entry/exit. But, TDX hardware can theoretically _deliver_ a virtualization exception (#VE) on any access to private memory. But, it's not as bad as it sounds. TDX can be configured to never deliver these exceptions on private memory with a "TD attribute" called ATTR_SEPT_VE_DISABLE. The guest has no way to *set* this attribute, but it can check it. Ensure ATTR_SEPT_VE_DISABLE is set in early boot. panic() if it is unset. There is no sane way for Linux to run with this attribute clear so a panic() is appropriate. There's small window during boot before the check where kernel has an early #VE handler. But the handler is only for port I/O and will also panic() as soon as it sees any other #VE, such as a one generated by a private memory access.

So it can calculate what is the page order needed to allocate for the received frames. The first problem was that, when the max MTU was calculated it was reading the value from dev and not from HW, so in this way it was missing L2 header + the FCS. The other problem was that once the skb is created using __build_skb_around, it would reserve some space for skb_shared_info. So if we received a frame which size is at the limit of the page order then the creating will failed because it would not have space to put all the data.

This actually has 2 issues: 1. It is using a length to map and a different length to unmap. 2. When the unmap was happening, the data was sync for cpu but it could be that this will overwrite what build_skb was initializing. The fix for these two problems is to change the order of operations. First to sync the frame for cpu, then to build the skb and in the end to unmap using the correct size but without sync the frame again for cpu.

If you press that jump key, menuconfig crashes with a segmentation fault. For example, do this: $ make ARCH=arm64 allnoconfig menuconfig Press '/' to search for the string "ACPI". Press '1' to choose "(1) Main menu". Then, menuconfig crashed with a segmentation fault. The following code in search_conf() conf(targets[i]->parent, targets[i]); results in NULL pointer dereference because targets[i] is the rootmenu, which does not have a parent. Commit d05377e184fc tried to fix the issue of top-level items not having a jump key, but adding the "Main menu" was not the right fix. The correct fix is to show the searched item itself.

That is pointless because that function always frees the ulist in case it returns an error. Also In some places like at test_multiple_refs(), after a call to btrfs_qgroup_account_extent() we also leave "old_roots" and "new_roots" pointing to ulists that were freed, because btrfs_qgroup_account_extent() has freed those ulists, and if after that the next call to btrfs_find_all_roots() fails, we call ulist_free() on the "old_roots" ulist again, resulting in a double free. So remove those calls to reduce the code size and avoid double ulist free in case of an error.

Keep the vmx_get_perf_capabilities() check for guest writes, even though it's technically unnecessary since the vCPU's PERF_CAPABILITIES is consulted when refreshing LBR support. A future patch will clean up vmx_get_perf_capabilities() to avoid the RDMSR on every call, at which point the paranoia will incur no meaningful overhead. Note, prior to vmx_get_perf_capabilities() checking that the host fully supports LBRs via x86_perf_get_lbr(), KVM effectively relied on intel_pmu_lbr_is_enabled() to guard against host userspace enabling LBRs on platforms without full support.

An SKB can be queued by the first flow and immediately dequeued and freed by the second flow, therefore the callers of l2cap_reassemble_sdu can't use the SKB after that function returns. However, some places continue accessing struct l2cap_ctrl that resides in the SKB's CB for a short time after l2cap_reassemble_sdu returns, leading to a use-after-free condition (the stack trace is below, line numbers for kernel 5.19.8).

Yet the problem is that, HCI core may not free the skb after handling ACL data packets. To be more specific, when start fragment does not contain the L2CAP length, HCI core just copies skb into conn->rx_skb and finishes frame process in l2cap_recv_acldata(), without freeing the skb, which triggers the above memory leak. This patch solves it by releasing the relative skb, after processing the above case in l2cap_recv_acldata().

The tracing subsystem allocates a per_cpu directory with access to the per CPU ring buffer via a cpuX file. But to save space, the ring buffer will only allocate buffers for online CPUs, even though the CPU array will be as big as the nr_cpu_ids. With the addition of waking waiters on the ring buffer when closing the file, the ring_buffer_wake_waiters() now needs to make sure that the buffer is allocated (with the irq_work allocated with it) before trying to wake waiters, as it will cause a NULL pointer dereference. While debugging this, I added a NULL check for the buffer itself (which is OK to do), and also NULL pointer checks against buffer->buffers (which is not fine, and will WARN) as well as making sure the CPU number passed in is within the nr_cpu_ids (which is also not fine if it isn't).

It was found from vmcore that perf had registered two ops with the same content successively, both dynamic. After unregistering the second ops, a use-after-free occurred. In ftrace_shutdown(), when the second ops is unregistered, the FTRACE_UPDATE_CALLS command is not set because there is another enabled ops with the same content. Also, both ops are dynamic and the ftrace callback function is ftrace_ops_list_func, so the FTRACE_UPDATE_TRACE_FUNC command will not be set. Eventually the value of 'command' will be 0 and ftrace_shutdown() will skip the rcu synchronization. However, ftrace may be activated. When the ops is released, another CPU may be accessing the ops. Add the missing synchronization to fix this problem.

The SRCU read lock is not technically required when no Shadow MMUs are in use, since the TDP MMU walks the paging structures from the roots and does not need to look up GFN translations in the memslots, but make the SRCU locking unconditional for simplicty. In most cases, the SRCU locking is taken care of in the vCPU run loop, but when called through other ioctls (such as KVM_SET_GUEST_DEBUG) there is no srcu_read_lock. Tested: ran tools/testing/selftests/kvm/x86_64/debug_regs on a DBG build. This patch causes the suspicious RCU warning to disappear. Note that the warning is hit in __kvm_zap_rmaps(), so kvm_memslots_have_rmaps() must return true in order for this to repro (i.e. the TDP MMU must be off or nesting in use.)

With more EFI based systems appearing that were not built to run Linux (such as the Windows-on-ARM laptops based on Qualcomm SOCs), as well as the introduction of PRM (platform specific firmware routines that are callable just like EFI runtime services), we are more likely to run into issues of this sort, and it is much more likely that we can identify and work around such issues if they don't bring down the system entirely. Since we already use a EFI runtime services call wrapper in assembler, we can quite easily add some code that captures the execution state at the point where the call is made, allowing us to revert to this state and proceed execution if the call triggered a synchronous exception. Given that the kernel and the firmware don't share any data structures that could end up in an indeterminate state, we can happily continue running, as long as we mark the EFI runtime services as unavailable from that point on.

However, the ID register structures used to select few compat cpufeatures (vfp, crc32, ...) are masked and hence such hwcaps do not appear in /proc/cpuinfo anymore for PER_LINUX32 personality. Add the ID register structures explicitly and set the relevant entry as visible. As these ID registers are now of type visible so make them available in 64-bit userspace by making necessary changes in register emulation logic and documentation.

As highlighted by the cxl-create-region.sh test [1], a single device may host multiple regions, but the driver was only tracking one region at a time. This leads to a situation where only the last enabled region per nvdimm device is cleaned up properly. Other regions are leaked, and this also causes cxl_memdev reference leaks. Fix the tracking by allowing cxl_nvdimm objects to track multiple region associations.

A compatible peer is a target that shares the same dport, and where that target's interleave position also routes it to the same dport. Compatibility is determined by the device's interleave position being >= to distance. For example, if a given dport can only map every Nth position then positions less than N away from the last target programmed are incompatible. The @distance for the host-bridge's cxl_port in a simple dual-ported host-bridge configuration with 2 direct-attached devices is 1, i.e. An x2 region divided by 2 dports to reach 2 region targets. An x4 region under an x2 host-bridge would need 2 intervening switches where the @distance at the host bridge level is 2 (x4 region divided by 2 switches to reach 4 devices). However, the distance between peers underneath a single ported host-bridge is always zero because there is no limit to the number of devices that can be mapped. In other words, there are no decoders to program in a passthrough, all descendants are mapped and distance only starts matters for the intervening descendant ports of the passthrough port. Add tracking for the number of dports mapped to a port, and use that to detect the passthrough case for calculating @distance.

If that region is destroyed and then a new one is created the region id increments. That ends up looking like a memory leak, or is otherwise surprising that identifiers roll forward even after destroying all previously created regions. Try to reuse rather than free old region ids at region release time. While this fixes a cosmetic issue, the needlessly advancing memory region-id gives the appearance of a memory leak, hence the "Fixes" tag, but no "Cc: stable" tag.

The local variable 'err' need to be initialized before goto out. The original code in __ext4_fill_super() is fine because it has two return values 'ret' and 'err' and 'ret' is initialized as -EINVAL. After we factor out ext4_load_and_init_journal(), this code is broken. So fix it by directly returning -EINVAL in the error handler path.
