2021-05-18signal: Factor force_sig_perf out of perf_sigtrapEric W. Biederman3-9/+16
Separate filling in siginfo for TRAP_PERF from deciding that siginal needs to be sent. There are enough little details that need to be correct when properly filling in siginfo_t that it is easy to make mistakes if filling in the siginfo_t is in the same function with other logic. So factor out force_sig_perf to reduce the cognative load of on reviewers, maintainers and implementors. v1: https://lkml.kernel.org/r/[email protected] v2: https://lkml.kernel.org/r/[email protected] Link: https://lkml.kernel.org/r/[email protected] Reviewed-by: Marco Elver <[email protected]> Acked-by: Peter Zijlstra (Intel) <[email protected]> Signed-off-by: "Eric W.

2021-05-18signal: Implement SIL_FAULT_TRAPNOEric W. Biederman3-27/+16
Now that si_trapno is part of the union in _si_fault and available on all architectures, add SIL_FAULT_TRAPNO and update siginfo_layout to return SIL_FAULT_TRAPNO when the code assumes si_trapno is valid. There is room for future changes to reduce when si_trapno is valid but this is all that is needed to make si_trapno and the other members of the the union in _sigfault mutually exclusive. Update the code that uses siginfo_layout to deal with SIL_FAULT_TRAPNO and have the same code ignore si_trapno in in all other cases. v1: https://lkml.kernel.org/r/[email protected] v2: https://lkml.kernel.org/r/[email protected] Link: https://lkml.kernel.org/r/[email protected] Reviewed-by: Marco Elver <[email protected]> Signed-off-by: "Eric W.

2021-05-18siginfo: Move si_trapno inside the union inside _si_faultEric W. Biederman4-8/+8
It turns out that linux uses si_trapno very sparingly, and as such it can be considered extra information for a very narrow selection of signals, rather than information that is present with every fault reported in siginfo. As such move si_trapno inside the union inside of _si_fault. This results in no change in placement, and makes it eaiser to extend _si_fault in the future as this reduces the number of special cases. In particular with si_trapno included in the union it is no longer a concern that the union must be pointer aligned on most architectures because the union follows immediately after si_addr which is a pointer. This change results in a difference in siginfo field placement on sparc and alpha for the fields si_addr_lsb, si_lower, si_upper, si_pkey, and si_perf. These architectures do not implement the signals that would use si_addr_lsb, si_lower, si_upper, si_pkey, and si_perf. Further these architecture have not yet implemented the userspace that would use si_perf. The point of this change is in fact to correct these placement issues before sparc or alpha grow userspace that cares. This change was discussed[1] and the agreement is that this change is currently safe.

restrack should only be attached to a cm_id while the ID has a valid device pointer. It is set up when the device is first loaded, but not cleared when the device is removed. There is also two copies of the device pointer, one private and one in the public API, and these were left out of sync. Make everything go to NULL together and manipulate restrack right around the device assignments.

In a guest that should support Architecture LBR, check_msr() will be a non-related check for the architecture MSR 0x0 (IA32_P5_MC_ADDR) that is also not supported by KVM. The failure will cause x86_pmu.lbr_nr = 0, thereby preventing the initialization of the guest Arch LBR. Fix it by avoiding this extraneous check in intel_pmu_init() for Arch LBR.

2021-05-17btrfs: release path before starting transaction when cloning inline extentFilipe Manana1-0/+5
When cloning an inline extent there are a few cases, such as when we have an implicit hole at file offset 0, where we start a transaction while holding a read lock on a leaf. Starting the transaction results in a call to sb_start_intwrite(), which results in doing a read lock on a percpu semaphore. Lockdep doesn't like this and complains about it: [46.580704] ====================================================== [46.580752] WARNING: possible circular locking dependency detected [46.580799] 5.13.0-rc1 #28 Not tainted [46.580832] ------------------------------------------------------ [46.580877] cloner/3835 is trying to acquire lock: [46.580918] c00000001301d638 (sb_internal#2){.+.+}-{0:0}, at: clone_copy_inline_extent+0xe4/0x5a0 [46.581167] [46.581167] but task is already holding lock: [46.581217] c000000007fa2550 (btrfs-tree-00){++++}-{3:3}, at: __btrfs_tree_read_lock+0x70/0x1d0 [46.581293] [46.581293] which lock already depends on the new lock.

In commit fa8b90070a80 ("quota: wire up quotactl_path") we have wired up new quotactl_path syscall. However some people in LWN discussion have objected that the path based syscall is missing dirfd and flags argument which is mostly standard for contemporary path based syscalls. Indeed they have a point and after a discussion with Christian Brauner and Sascha Hauer I've decided to disable the syscall for now and update its API. Since there is no userspace currently using that syscall and it hasn't been released in any major release, we should be fine.

As kvmgt module contains all handling for VFIO/mdev, leaving mdev attribute groups in gvt module caused dependency issue. Although it was there for possible other hypervisor usage, that turns out never to be true. So this moves all mdev handling into kvmgt module completely to resolve dependency issue. With this fix, no config workaround is required. So revert previous workaround commits: adaeb718d46f ("vfio/gvt: fix DRM_I915_GVT dependency on VFIO_MDEV") and 07e543f4f9d1 ("vfio/gvt: Make DRM_I915_GVT depend on VFIO_MDEV").

2021-05-17module: check for exit sections in layout_sections() instead of ↵Jessica Yu1-6/+11
module_init_section() Previously, when CONFIG_MODULE_UNLOAD=n, the module loader just does not attempt to load exit sections since it never expects that any code in those sections will ever execute. However, dynamic code patching (alternatives, jump_label and static_call) can have sites in __exit code, even if __exit is never executed. Therefore __exit must be present at runtime, at least for as long as __init code is. Commit 33121347fb1c ("module: treat exit sections the same as init sections when !CONFIG_MODULE_UNLOAD") solves the requirements of jump_labels and static_calls by putting the exit sections in the init region of the module so that they are at least present at init, and discarded afterwards. It does this by including a check for exit sections in module_init_section(), so that it also returns true for exit sections, and the module loader will automatically sort them in the init region of the module. However, the solution there was not completely arch-independent. ARM is a special case where it supplies its own module_{init, exit}_section() functions. Instead of pushing the exit section checks into module_init_section(), just implement the exit section check in layout_sections(), so that we don't have to touch arch-dependent code.

2021-05-16xfs: adjust rt allocation minlen when extszhint > rtextsizeDarrick J. Wong1-26/+57
xfs_bmap_rtalloc doesn't handle realtime extent files with extent size hints larger than the rt volume's extent size properly, because xfs_bmap_extsize_align can adjust the offset/length parameters to try to fit the extent size hint. Under these conditions, minlen has to be large enough so that any allocation returned by xfs_rtallocate_extent will be large enough to cover at least one of the blocks that the caller asked for. If the allocation is too short, bmapi_write will return no mapping for the requested range, which causes ENOSPC errors in other parts of the filesystem. Therefore, adjust minlen upwards to fix this. This can be found by running generic/263 (g/127 or g/522) with a realtime extent size hint that's larger than the rt volume extent size. Signed-off-by: Darrick J.

2021-05-16ALSA: intel8x0: Don't update period unless preparedTakashi Iwai1-0/+7
The interrupt handler of intel8x0 calls snd_intel8x0_update() whenever the hardware sets the corresponding status bit for each stream. This works fine for most cases as long as the hardware behaves properly. But when the hardware gives a wrong bit set, this leads to a zero- division Oops, and reportedly, this seems what happened on a VM. For fixing the crash, this patch adds a internal flag indicating that the stream is ready to be updated, and check it (as well as the flag being in suspended) to ignore such spurious update.

When devm_ioremap_resource() fails, a clear enough error message will be printed by its subfunction __devm_ioremap_resource(). The error information contains the device name, failure cause, and possibly resource information. Therefore, remove the error printing here to simplify code and reduce the binary size.

2021-05-15scsi: pm80xx: Fix drives missing during rmmod/insmod loopAjish Koshy4-12/+19
When driver is loaded after rmmod some drives are not showing up during discovery. SATA drives are directly attached to the controller connected phys. During device discovery, the IDENTIFY command (qc timeout (cmd 0xec)) is timing out during revalidation. This will trigger abort from host side and controller successfully aborts the command and returns success. Post this successful abort response ATA library decides to mark the disk as NODEV. To overcome this, inside pm8001_scan_start() after phy_start() call, add get start response and wait for few milliseconds to trigger next phy start. This millisecond delay will give sufficient time for the controller state machine to accept next phy start.
