2021-09-02mm: don't allow oversized kvmalloc() callsLinus Torvalds
'kvmalloc()' is a convenience function for people who want to do a kmalloc() but fall back on vmalloc() if there aren't enough physically contiguous pages, or if the allocation is larger than what kmalloc() supports. However, let's make sure it doesn't get _too_ easy to do crazy things with it. In particular, don't allow big allocations that could be due to integer overflow or underflow. So make sure the allocation size fits in an 'int', to protect against trivial integer conversion issues.

2021-09-02Merge tag 'xfs-5.15-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linuxLinus Torvalds
Pull xfs updates from Darrick Wong: "There's a lot in this cycle. Starting with bug fixes: To avoid livelocks between the logging code and the quota code, we've disabled the ability of quotaoff to turn off quota accounting. (Admins can still disable quota enforcement, but truly turning off accounting requires a remount.) We've tried to do this in a careful enough way that there shouldn't be any user visible effects aside from quotaoff no longer randomly hanging the system. We've also fixed some bugs in runtime log behavior that could trip up log recovery if (otherwise unrelated) transactions manage to start and commit concurrently; some bugs in the GETFSMAP ioctl where we would incorrectly restrict the range of records output if the two xfs devices are of different sizes; a bug that resulted in fallocate funshare failing unnecessarily; and broken behavior in the xfs inode cache when DONTCACHE is in play. As for new features: we now batch inode inactivations in percpu background threads, which sharply decreases frontend thread wait time when performing file deletions and should improve overall directory tree deletion times. This eliminates both the problem where closing an unlinked file (especially on a frozen fs) can stall for a long time, and should also ease complaints about direct reclaim bogging down on unlinked file cleanup. Starting with this release, we've enabled pipelining of the XFS log. On workloads with high rates of metadata updates to different shards of the filesystem, multiple threads can be used to format committed log updates into log checkpoints. Lastly, with this release, two new features have graduated to supported status: inode btree counters (for faster mounts), and support for dates beyond Y2038. Expect these to be enabled by default in a future release of xfsprogs. Summary: - Fix a potential log livelock on busy filesystems when there's so much work going on that we can't finish a quotaoff before filling up the log by removing the ability to disable quota accounting. - Introduce the ability to use per-CPU data structures in XFS so that we can do a better job of maintaining CPU locality for certain operations. - Defer inode inactivation work to per-CPU lists, which will help us batch that processing. Deletions of large sparse files will *appear* to run faster, but all that means is that we've moved the work to the backend. - Drop the EXPERIMENTAL warnings from the y2038+ support and the inode btree counters, since it's been nearly a year and no complaints have come in. - Remove more of our bespoke kmem* variants in favor of using the standard Linux calls. - Prepare for the addition of log incompat features in upcoming cycles by actually adding code to support this. - Small cleanups of the xattr code in preparation for landing support for full logging of extended attribute updates in a future cycle. - Replace the various log shutdown state and flag code all over xfs with a single atomic bit flag. - Fix a serious log recovery bug where log item replay can be skipped based on the start lsn of a transaction even though the transaction commit lsn is the key data point for that by enforcing start lsns to appear in the log in the same order as commit lsns. - Enable pipelining in the code that pushes log items to disk. - Drop ->writepage. - Fix some bugs in GETFSMAP where the last fsmap record reported for a device could extend beyond the end of the device, and a separate bug where query keys for one device could be applied to another. - Don't let GETFSMAP query functions edit their input parameters. - Small cleanups to the scrub code's handling of perag structures. - Small cleanups to the incore inode tree walk code. - Constify btree function parameters that aren't changed, so that there will never again be confusion about range query functions changing their input parameters. - Standardize the format and names of tracepoint data attributes. - Clean up all the mount state and feature flags to use wrapped bitset functions instead of inconsistently open-coded flag checks. - Fix some confusion between xfs_buf hash table key variable vs. block number. - Fix a mis-interaction with iomap where we reported shared delalloc cow fork extents to iomap, which would cause the iomap unshare operation to return IO errors unnecessarily. - Fix DONTCACHE behavior" * tag 'xfs-5.15-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (103 commits) xfs: fix I_DONTCACHE xfs: only set IOMAP_F_SHARED when providing a srcmap to a write xfs: fix perag structure refcounting error when scrub fails xfs: rename buffer cache index variable b_bn xfs: convert bp->b_bn references to xfs_buf_daddr() xfs: introduce xfs_buf_daddr() xfs: kill xfs_sb_version_has_v3inode() xfs: introduce xfs_sb_is_v5 helper xfs: remove unused xfs_sb_version_has wrappers xfs: convert xfs_sb_version_has checks to use mount features xfs: convert scrub to use mount-based feature checks xfs: open code sb verifier feature checks xfs: convert xfs_fs_geometry to use mount feature checks xfs: replace XFS_FORCED_SHUTDOWN with xfs_is_shutdown xfs: convert remaining mount flags to state flags xfs: convert mount flags to features xfs: consolidate mount option features in m_features xfs: replace xfs_sb_version checks with feature flag checks xfs: reflect sb features in xfs_mount xfs: rework attr2 feature and mount options ...

2021-09-01parisc: fix crash with signals and allocaMikulas Patocka
I was debugging some crashes on parisc and I found out that there is a crash possibility if a function using alloca is interrupted by a signal. The reason for the crash is that the gcc alloca implementation leaves garbage in the upper 32 bits of the sp register. This normally doesn't matter (the upper bits are ignored because the PSW W-bit is clear), however the signal delivery routine in the kernel uses full 64 bits of sp and it fails with -EFAULT if the upper 32 bits are not zero. I created this program that demonstrates the problem: #include <stdlib.h> #include <unistd.h> #include <signal.h> #include <alloca.h> static __attribute__((noinline,noclone)) void aa(int *size) { void * volatile p = alloca(-*size); while (1) ; } static void handler(int sig) { write(1, "signal delivered\n", 17); _exit(0); } int main(void) { int size = -0x100; signal(SIGALRM, handler); alarm(1); aa(&size); } If you compile it with optimizations, it will crash. The "aa" function has this disassembly: 000106a0 <aa>: 106a0: 08 03 02 41 copy r3,r1 106a4: 08 1e 02 43 copy sp,r3 106a8: 6f c1 00 80 stw,ma r1,40(sp) 106ac: 37 dc 3f c1 ldo -20(sp),ret0 106b0: 0c 7c 12 90 stw ret0,8(r3) 106b4: 0f 40 10 9c ldw 0(r26),ret0 ; ret0 = 0x00000000FFFFFF00 106b8: 97 9c 00 7e subi 3f,ret0,ret0 ; ret0 = 0xFFFFFFFF0000013F 106bc: d7 80 1c 1a depwi 0,31,6,ret0 ; ret0 = 0xFFFFFFFF00000100 106c0: 0b 9e 0a 1e add,l sp,ret0,sp ; sp = 0xFFFFFFFFxxxxxxxx 106c4: e8 1f 1f f7 b,l,n 106c4 <aa+0x24>,r0 This patch fixes the bug by truncating the "usp" variable to 32 bits.

2021-09-01parisc: Fix compile failure when building 64-bit kernel nativelyMasahiro Yamada
Commit 23243c1ace9f ("arch: use cross_compiling to check whether it is a cross build or not") broke 64-bit parisc builds on 32-bit parisc systems. Helge mentioned: - 64-bit parisc userspace is not supported yet [1] - hppa gcc does not support "-m64" flag [2] That means, parisc developers working on a 32-bit parisc machine need to use hppa64-linux-gnu-gcc (cross compiler) for building the 64-bit parisc kernel. After the offending commit, gcc is used in such a case because both $(SRCARCH) and $(SUBARCH) are 'parisc', hence cross_compiling is unset. A correct way is to introduce ARCH=parisc64 because building the 64-bit parisc kernel on a 32-bit parisc system is not exactly a native build, but rather a semi-cross build.

In most other configurations, <linux/acpi.h> continued to be included through at least <linux/tboot.h> if CONFIG_INTEL_TXT was enabled, and there were probably other implicit include paths too. Add acpi.h explicitly so there is no more error, and so that we don't continue to depend on these unreliable implicit include paths.

Also included in here are the counter driver subsystem updates as the IIO drivers needed them. Lots of churn in some staging drivers, we dropped the "old" rtl8188eu driver and replaced it with a newer version of the driver that had been maintained out-of-tree by Larry with the end goal of actually being able to get this driver out of staging eventually. Despite that driver being "newer" the line count of this pull request is going up. Some drivers moved out of staging as well, which is always nice to see, that is why there are additions to the mfc and misc driver subsystems. All of these were acked by the various subsystem maintainers involved. But by far, as normal, it's coding style cleanups all over the drivers/staging/ tree in here. Full details of these changes are in the shortlog.

2021-09-01fs: dlm: avoid comms shutdown delay in release_lockspaceAlexander Aring
When dlm_release_lockspace does active shutdown on connections to other nodes, the active shutdown will wait for any exisitng passive shutdowns to be resolved. But, the sequence of operations during dlm_release_lockspace can prevent the normal resolution of passive shutdowns (processed normally by way of lockspace recovery.) This disruption of passive shutdown handling can cause the active shutdown to wait for a full timeout period, delaying the completion of dlm_release_lockspace. To fix this, make dlm_release_lockspace resolve existing passive shutdowns (by calling dlm_clear_members earlier), before it does active shutdowns. The active shutdowns will not find any passive shutdowns to wait for, and will not be delayed.

An unnecessary "__ref" annotation was removed from the "drivers/pci/xen_pcifront.c" file. The function where the annotation was used was "pcifront_backend_changed()", which does not call any functions annotated as "__*init" nor "__*exit". This makes "__ref" unnecessary since this annotation is used to make the compiler ignore section miss-matches when they are not happening here in the first place. In addition to the aforementioned change, some code style issues were fixed in the same file.

Other than that, all are minor cleanups" * 'for-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: Remove unused WORK_NO_COLOR workqueue: Assign a color to barrier work items workqueue: Mark barrier work with WORK_STRUCT_INACTIVE workqueue: Change the code of calculating work_flags in insert_wq_barrier() workqueue: Change arguement of pwq_dec_nr_in_flight() workqueue: Rename "delayed" (delayed by active management) to "inactive" workqueue: Replace deprecated CPU-hotplug functions. workqueue: Replace deprecated ida_simple_*() with ida_alloc()/ida_free() workqueue: Fix typo in comments workqueue: Fix possible memory leaks in wq_numa_init()
