2023-01-30net: stmmac: do not stop RX_CLK in Rx LPI state for qcs404 SoCAndrey Konovalov1-0/+1
Currently in phy_init_eee() the driver unconditionally configures the PHY to stop RX_CLK after entering Rx LPI state. This causes an LPI interrupt storm on my qcs404-base board. Change the PHY initialization so that for "qcom,qcs404-ethqos" compatible device RX_CLK continues to run even in Rx LPI state.

2023-01-25bpf, sockmap: Check for any of tcp_bpf_prots when cloning a listenerJakub Sitnicki1-0/+12
A listening socket linked to a sockmap has its sk_prot overridden. It points to one of the struct proto variants in tcp_bpf_prots. The variant depends on the socket's family and which sockmap programs are attached. A child socket cloned from a TCP listener initially inherits their sk_prot. But before cloning is finished, we restore the child's proto to the listener's original non-tcp_bpf_prots one. This happens in tcp_create_openreq_child -> tcp_bpf_clone. Today, in tcp_bpf_clone we detect if the child's proto should be restored by checking only for the TCP_BPF_BASE proto variant. This is not correct. The sk_prot of listening socket linked to a sockmap can point to to any variant in tcp_bpf_prots. If the listeners sk_prot happens to be not the TCP_BPF_BASE variant, then the child socket unintentionally is left if the inherited sk_prot by tcp_bpf_clone. This leads to issues like infinite recursion on close [1], because the child state is otherwise not set up for use with tcp_bpf_prot operations. Adjust the check in tcp_bpf_clone to detect all of tcp_bpf_prots variants. Note that it wouldn't be sufficient to check the socket state when overriding the sk_prot in tcp_bpf_update_proto in order to always use the TCP_BPF_BASE variant for listening sockets. Since commit b8b8315e39ff ("bpf, sockmap: Remove unhash handler for BPF sockmap usage") it is possible for a socket to transition to TCP_LISTEN state while already linked to a sockmap, e.g. connect() -> insert into map -> connect(AF_UNSPEC) -> listen().

2023-01-24platform/x86: apple-gmux: Add apple_gmux_detect() helperHans de Goede1-2/+84
Add a new (static inline) apple_gmux_detect() helper to apple-gmux.h which can be used for gmux detection instead of apple_gmux_present(). The latter is not really reliable since an ACPI device with a HID of APP000B is present on some devices without a gmux at all, as well as on devices with a newer (unsupported) MMIO based gmux model. This causes apple_gmux_present() to return false-positives on a number of different Apple laptop models. This new helper uses the same probing as the actual apple-gmux driver, so that it does not return false positives. To avoid code duplication the gmux_probe() function of the actual driver is also moved over to using the new apple_gmux_detect() helper. This avoids false positives (vs _HID + IO region detection) on: MacBookPro5,4 https://pastebin.com/8Xjq7RhS MacBookPro8,1 https://linux-hardware.org/?probe=e513cfbadb&log=dmesg MacBookPro9,2 https://bugzilla.kernel.org/attachment.cgi?id=278961 MacBookPro10,2 https://lkml.org/lkml/2014/9/22/657 MacBookPro11,2 https://forums.fedora-fr.org/viewtopic.php?id=70142 MacBookPro11,4 https://raw.githubusercontent.com/im-0/investigate-card-reader-suspend-problem-on-mbp11.4/master/test-16/dmesg Fixes: 21245df307cb ("ACPI: video: Add Apple GMUX brightness control detection") Link: https://lore.kernel.org/platform-driver-x86/20230123113750.462144-1-hdegoede@redhat.com/ Reported-by: Emmanouil Kouroupakis <kartebi@gmail.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20230124105754.62167-3-hdegoede@redhat.com

2023-01-17USB: fix misleading usb_set_intfdata() kernel docJohan Hovold1-8/+7
The struct device driver-data pointer is used for any data that a driver may need in various callbacks while bound to the device. For convenience, subsystems typically provide wrappers such as usb_set_intfdata() of the generic accessor functions for use in bus callbacks. There is generally no longer any need for a driver to clear the pointer, but since commit 0998d0631001 ("device-core: Ensure drvdata = NULL when no driver is bound") the driver-data pointer is set to NULL by driver core post unbind anyway. For historical reasons, USB core also clears this pointer when an explicitly claimed interface is released. Due to a misunderstanding, a misleading kernel doc comment for usb_set_intfdata() was recently added which claimed that the driver data pointer must not be cleared during disconnect before "all actions [are] completed", which is both imprecise and incorrect. Specifically, drivers like cdc-acm which claim additional interfaces use the driver-data pointer as a flag which is cleared when the first interface is unbound. As long as a driver does not do something odd like dereference the pointer in, for example, completion callbacks, this can be done at any time during disconnect. And in any case this is no different than for any other resource, like the driver data itself, which may be freed by the disconnect callback. Note that the comment actually also claimed that the interface itself was somehow being set to NULL by driver core. Fix the kernel doc by removing incorrect, overly specific and misleading details and adding a comment about why some drivers do clear the driver-data pointer.

2023-01-13efi: tpm: Avoid READ_ONCE() for accessing the event logArd Biesheuvel1-2/+2
Nathan reports that recent kernels built with LTO will crash when doing EFI boot using Fedora's GRUB and SHIM. The culprit turns out to be a misaligned load from the TPM event log, which is annotated with READ_ONCE(), and under LTO, this gets translated into a LDAR instruction which does not tolerate misaligned accesses. Interestingly, this does not happen when booting the same kernel straight from the UEFI shell, and so the fact that the event log may appear misaligned in memory may be caused by a bug in GRUB or SHIM. However, using READ_ONCE() to access firmware tables is slightly unusual in any case, and here, we only need to ensure that 'event' is not dereferenced again after it gets unmapped, but this is already taken care of by the implicit barrier() semantics of the early_memunmap() call.

While compile-testing randconfig builds for the upcoming boardfile removal, I noticed that an earlier patch of mine was completely broken, and the introduction of CONFIG_ARCH_OMAP1_ANY only replaced one set of build failures with another one, now resulting in link failures like ld: drivers/video/fbdev/omap/omapfb_main.o: in function `omapfb_do_probe': drivers/video/fbdev/omap/omapfb_main.c:1703: undefined reference to `omap_set_dma_priority' ld: drivers/dma/ti/omap-dma.o: in function `omap_dma_free_chan_resources': drivers/dma/ti/omap-dma.c:777: undefined reference to `omap_free_dma' drivers/dma/ti/omap-dma.c:1685: undefined reference to `omap_get_plat_info' ld: drivers/usb/gadget/udc/omap_udc.o: in function `next_in_dma': drivers/usb/gadget/udc/omap_udc.c:820: undefined reference to `omap_get_dma_active_status' I tried reworking it, but the resulting patch ended up much bigger than simply avoiding the original problem of unused-function warnings like arch/arm/mach-omap1/mcbsp.c:76:30: error: unused variable 'omap1_mcbsp_ops' [-Werror,-Wunused-variable] As a result, revert the previous fix, and rearrange the code that produces warnings to hide them. For mcbsp, the #ifdef check can simply be removed as the cpu_is_omapxxx() checks already achieve the same result, while in the io.c the easiest solution appears to be to merge the common map bits into each soc specific portion. This gets cleaned in a nicer way after omap7xx support gets dropped, as the remaining SoCs all have the exact same I/O map.

2023-01-10net/mlx5: Fix command stats access after freeMoshe Shemesh1-1/+1
Command may fail while driver is reloading and can't accept FW commands till command interface is reinitialized. Such command failure is being logged to command stats. This results in NULL pointer access as command stats structure is being freed and reallocated during mlx5 devlink reload (see kernel log below). Fix it by making command stats statically allocated on driver probe.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for net: 1) Use signed integer in ipv6_skip_exthdr() called from nf_confirm(). Reported by static analysis tooling, patch from Florian Westphal. 2) Missing set type checks in nf_tables: Validate that set declaration matches the an existing set type, otherwise bail out with EEXIST. Currently, nf_tables silently accepts the re-declaration with a different type but it bails out later with EINVAL when the user adds entries to the set. This fix is relatively large because it requires two preparation patches that are included in this batch. 3) Do not ignore updates of timeout and gc_interval parameters in existing sets. 4) Fix a hang when 0/0 subnets is added to a hash:net,port,net type of ipset. Except hash:net,port,net and hash:net,iface, the set types don't support 0/0 and the auxiliary functions rely on this fact. So 0/0 needs a special handling in hash:net,port,net which was missing (hash:net,iface was not affected by this bug), from Jozsef Kadlecsik. 5) When adding/deleting large number of elements in one step in ipset, it can take a reasonable amount of time and can result in soft lockup errors. This patch is a complete rework of the previous version in order to use a smaller internal batch limit and at the same time removing the external hard limit to add arbitrary number of elements in one step. Also from Jozsef Kadlecsik. Except for patch #1, which fixes a bug introduced in the previous net-next development cycle, anything else has been broken for several releases. ==================== Signed-off-by: David S.

2023-01-02netfilter: ipset: Rework long task execution when adding/deleting entriesJozsef Kadlecsik1-1/+1
When adding/deleting large number of elements in one step in ipset, it can take a reasonable amount of time and can result in soft lockup errors. The patch 5f7b51bf09ba ("netfilter: ipset: Limit the maximal range of consecutive elements to add/delete") tried to fix it by limiting the max elements to process at all. However it was not enough, it is still possible that we get hung tasks. Lowering the limit is not reasonable, so the approach in this patch is as follows: rely on the method used at resizing sets and save the state when we reach a smaller internal batch limit, unlock/lock and proceed from the saved state. Thus we can avoid long continuous tasks and at the same time removed the limit to add/delete large number of elements in one step. The nfnl mutex is held during the whole operation which prevents one to issue other ipset commands in parallel.

2023-01-02ceph: avoid use-after-free in ceph_fl_release_lock()Xiubo Li1-0/+3
When ceph releasing the file_lock it will try to get the inode pointer from the fl->fl_file, which the memory could already be released by another thread in filp_close(). Because in VFS layer the fl->fl_file doesn't increase the file's reference counter. Will switch to use ceph dedicate lock info to track the inode. And in ceph_fl_release_lock() we should skip all the operations if the fl->fl_u.ceph.inode is not set, which should come from the request file_lock. And we will set fl->fl_u.ceph.inode when inserting it to the inode lock list, which is when copying the lock.

2022-12-28net/mlx5: E-Switch, properly handle ingress tagged packets on VSTMoshe Shemesh2-1/+7
Fix SRIOV VST mode behavior to insert cvlan when a guest tag is already present in the frame. Previous VST mode behavior was to drop packets or override existing tag, depending on the device version. In this patch we fix this behavior by correctly building the HW steering rule with a push vlan action, or for older devices we ask the FW to stack the vlan when a vlan is already present.

Commands like Write Zeros can change the contents of a namespaces without actually transferring data. To protect against this, check the Commands Supported and Effects log is supported by the controller for any unprivileg command passthrough and refuse unprivileged passthrough if the command has any effects that can change data or metadata. Note: While the Commands Support and Effects log page has only been mandatory since NVMe 2.0, it is widely supported because Windows requires it for any command passthrough from userspace.
