2022-09-26btrfs: send: add support for fs-verityBoris Burkov1-0/+3
Preserve the fs-verity status of a btrfs file across send/recv. There is no facility for installing the Merkle tree contents directly on the receiving filesystem, so we package up the parameters used to enable verity found in the verity descriptor. This gives the receive side enough information to properly enable verity again. Note that this means that receive will have to re-compute the whole Merkle tree, similar to how compression worked before encoded_write. Since the file becomes read-only after verity is enabled, it is important that verity is added to the send stream after any file writes. Therefore, when we process a verity item, merely note that it happened, then actually create the command in the send stream during 'finish_inode_if_needed'. This also creates V3 of the send stream format, without any format changes besides adding the new commands and attributes.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core fixes from Greg KH: "Here are two tiny driver core fixes for 6.0-rc7 that resolve some oft-reported problems. The first is a revert of the "fw_devlink.strict=1" default option that we keep trying to enable, but we keep finding platforms that this just breaks everything on. So again, we need it reverted and hopefully it can be worked on in future releases. The second is a sysfs file-size bugfix that resolves an issue that many people are starting to hit as the fix it is fixing also was backported to stable kernels. The util-linux developers are starting to get bugreports about sysfs files that contain no data because of this problem, and this fix which has been in linux-next in the bitfield tree for a long time, resolves it. I'm submitting it here as it needs to be merged for 6.0-final, not for 6.1-rc1.

2022-09-23vmlinux.lds.h: CFI: Reduce alignment of jump-table to function alignmentWill Deacon1-2/+1
Due to undocumented, hysterical raisins on x86, the CFI jump-table sections in .text are needlessly aligned to PMD_SIZE in the vmlinux linker script. When compiling a CFI-enabled arm64 kernel with a 64KiB page-size, a PMD maps 512MiB of virtual memory and so the .text section increases to a whopping 940MiB and blows the final Image up to 960MiB. Others report a link failure. Since the CFI jump-table requires only instruction alignment, reduce the alignment directives to function alignment for parity with other parts of the .text section. This reduces the size of the .text section for the aforementioned 64KiB page size arm64 kernel to 19MiB for a much more reasonable total Image size of 39MiB.

2022-09-11iommu/vt-d: Fix possible recursive locking in intel_iommu_init()Lu Baolu1-1/+3
The global rwsem dmar_global_lock was introduced by commit 3a5670e8ac932 ("iommu/vt-d: Introduce a rwsem to protect global data structures"). It is used to protect DMAR related global data from DMAR hotplug operations. The dmar_global_lock used in the intel_iommu_init() might cause recursive locking issue, for example, intel_iommu_get_resv_regions() is taking the dmar_global_lock from within a section where intel_iommu_init() already holds it via probe_acpi_namespace_devices(). Using dmar_global_lock in intel_iommu_init() could be relaxed since it is unlikely that any IO board must be hot added before the IOMMU subsystem is initialized. This eliminates the possible recursive locking issue by moving down DMAR hotplug support after the IOMMU is initialized and removing the uses of dmar_global_lock in intel_iommu_init().

2022-09-08fs: only do a memory barrier for the first set_buffer_uptodate()Linus Torvalds1-0/+11
Commit d4252071b97d ("add barriers to buffer_uptodate and set_buffer_uptodate") added proper memory barriers to the buffer head BH_Uptodate bit, so that anybody who tests a buffer for being up-to-date will be guaranteed to actually see initialized state. However, that commit didn't _just_ add the memory barrier, it also ended up dropping the "was it already set" logic that the BUFFER_FNS() macro had. That's conceptually the right thing for a generic "this is a memory barrier" operation, but in the case of the buffer contents, we really only care about the memory barrier for the _first_ time we set the bit, in that the only memory ordering protection we need is to avoid anybody seeing uninitialized memory contents. Any other access ordering wouldn't be about the BH_Uptodate bit anyway, and would require some other proper lock (typically BH_Lock or the folio lock). A reader that races with somebody invalidating the buffer head isn't an issue wrt the memory ordering, it's a serialization issue. Now, you'd think that the buffer head operations don't matter in this day and age (and I certainly thought so), but apparently some loads still end up being heavy users of buffer heads. In particular, the kernel test robot reported that not having this bit access optimization in place caused a noticeable direct IO performance regression on ext4: fxmark.ssd_ext4_no_jnl_DWTL_54_directio.works/sec -26.5% regression although you presumably need a fast disk and a lot of cores to actually notice.

2022-09-07net: skb: export skb drop reaons to user by TRACE_DEFINE_ENUMMenglong Dong2-1/+81
As Eric reported, the 'reason' field is not presented when trace the kfree_skb event by perf: $ perf record -e skb:kfree_skb -a sleep 10 $ perf script ip_defrag 14605 [021] 221.614303: skb:kfree_skb: skbaddr=0xffff9d2851242700 protocol=34525 location=0xffffffffa39346b1 reason: The cause seems to be passing kernel address directly to TP_printk(), which is not right. As the enum 'skb_drop_reason' is not exported to user space through TRACE_DEFINE_ENUM(), perf can't get the drop reason string from the 'reason' field, which is a number. Therefore, we introduce the macro DEFINE_DROP_REASON(), which is used to define the trace enum by TRACE_DEFINE_ENUM(). With the help of DEFINE_DROP_REASON(), now we can remove the auto-generate that we introduced in the commit ec43908dd556 ("net: skb: use auto-generation to convert skb drop reason to string"), and define the string array 'drop_reasons'. Hmmmm...now we come back to the situation that have to maintain drop reasons in both enum skb_drop_reason and DEFINE_DROP_REASON. But they are both in dropreason.h, which makes it easier. After this commit, now the format of kfree_skb is like this: $ cat /tracing/events/skb/kfree_skb/format name: kfree_skb ID: 1524 format: field:unsigned short common_type; offset:0; size:2; signed:0; field:unsigned char common_flags; offset:2; size:1; signed:0; field:unsigned char common_preempt_count; offset:3; size:1; signed:0; field:int common_pid; offset:4; size:4; signed:1; field:void * skbaddr; offset:8; size:8; signed:0; field:void * location; offset:16; size:8; signed:0; field:unsigned short protocol; offset:24; size:2; signed:0; field:enum skb_drop_reason reason; offset:28; size:4; signed:0; print fmt: "skbaddr=%p protocol=%u location=%p reason: %s", REC->skbaddr, REC->protocol, REC->location, __print_symbolic(REC->reason, { 1, "NOT_SPECIFIED" }, { 2, "NO_SOCKET" } ......

2022-09-05RDMA/mlx5: Rely on RoCE fw cap instead of devlink when setting profileMaher Sanalla1-9/+10
When the RDMA auxiliary driver probes, it sets its profile based on devlink driverinit value. The latter might not be in sync with FW yet (In case devlink reload is not performed), thus causing a mismatch between RDMA driver and FW. This results in the following FW syndrome when the RDMA driver tries to adjust RoCE state, which fails the probe: "0xC1F678 | modify_nic_vport_context: roce_en set on a vport that doesn't support roce" To prevent this, select the PF profile based on FW RoCE capability instead of relying on devlink driverinit value. To provide backward compatibility of the RoCE disable feature, on older FW's where roce_rw is not set (FW RoCE capability is read-only), keep the current behavior e.g., rely on devlink driverinit value.

It turns out that even after more than a year or development and testing, there's not full agreement on whether just using plain ordered notifications is Good Enough to avoid the complexity of using the notifications slots. Because of that, we decided that it's best left to a future final decision. We can always bring back this feature, but we can't really change it or remove it once we've released 6.0 with it enabled. The reverts leave the usual CQE notifications as the primary interface for knowing when data was sent, and when it was acked.

2022-09-02drm/edid: Handle EDID 1.4 range descriptor h/vfreq offsetsVille Syrjälä2-2/+7
EDID 1.4 introduced some extra flags in the range descriptor to support min/max h/vfreq >= 255. Consult them to correctly parse the vfreq limits. Note that some combinations of the flags are documented as "reserved" (as are some other values in the descriptor) but explicitly checking for those doesn't seem particularly worthwile since we end up with bogus results whether we decode them or not. v2: Increase the storage to u16 to make it work (Jani) Note the "reserved" values situation (Jani) v3: Document the EDID version number in the defines Drop some bogus (u8) casts Cc: stable@vger.kernel.org Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/6519 References: https://gitlab.freedesktop.org/drm/intel/-/issues/6484 Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220826213501.31490-2-ville.syrjala@linux.intel.com Reviewed-by: Manasi Navare <manasi.d.navare@intel.com>
2022-09-02spi: mux: Fix mux interaction with fast path optimisationsMark Brown1-0/+2
The spi-mux driver is rather too clever and attempts to resubmit any message that is submitted to it to the parent controller with some adjusted callbacks. This does not play at all nicely with the fast path which now sets flags on the message indicating that it's being handled through the fast path, we see async messages flagged as being on the fast path. Ideally the spi-mux code would duplicate the message but that's rather invasive and a bit fragile in that it relies on the mux knowing which fields in the message to copy. Instead teach the core that there are controllers which can't cope with the fast path and have the mux flag itself as being such a controller, ensuring that messages going via the mux don't get partially handled via the fast path. This will reduce the performance of any spi-mux connected device since we'll now always use the thread for both the actual controller and the mux controller instead of just the actual controller but given that we were always hitting the slow path anyway it's hopefully not too much of an additional cost and it allows us to keep the fast path.
