git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull hardening updates from Kees Cook: "There are three areas of note: A bunch of strlcpy()->strscpy() conversions ended up living in my tree since they were either Acked by maintainers for me to carry, or got ignored for multiple weeks (and were trivial changes). The compiler option '-fstrict-flex-arrays=3' has been enabled globally, and has been in -next for the entire devel cycle. This changes compiler diagnostics (though mainly just -Warray-bounds which is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_ coverage. In other words, there are no new restrictions, just potentially new warnings. Any new FORTIFY warnings we've seen have been fixed (usually in their respective subsystem trees). For more details, see commit df8fc4e934c12b. The under-development compiler attribute __counted_by has been added so that we can start annotating flexible array members with their associated structure member that tracks the count of flexible array elements at run-time. It is possible (likely?) that the exact syntax of the attribute will change before it is finalized, but GCC and Clang are working together to sort it out. Any changes can be made to the macro while we continue to add annotations. As an example of that last case, I have a treewide commit waiting with such annotations found via Coccinelle: https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b Also see commit dd06e72e68bcb4 for more details. Summary: - Fix KMSAN vs FORTIFY in strlcpy/strlcat (Alexander Potapenko) - Convert strreplace() to return string start (Andy Shevchenko) - Flexible array conversions (Arnd Bergmann, Wyes Karny, Kees Cook) - Add missing function prototypes seen with W=1 (Arnd Bergmann) - Fix strscpy() kerndoc typo (Arne Welzel) - Replace strlcpy() with strscpy() across many subsystems which were either Acked by respective maintainers or were trivial changes that went ignored for multiple weeks (Azeem Shaikh) - Remove unneeded cc-option test for UBSAN_TRAP (Nick Desaulniers) - Add KUnit tests for strcat()-family - Enable KUnit tests of FORTIFY wrappers under UML - Add more complete FORTIFY protections for strlcat() - Add missed disabling of FORTIFY for all arch purgatories. - Enable -fstrict-flex-arrays=3 globally - Tightening UBSAN_BOUNDS when using GCC - Improve checkpatch to check for strcpy, strncpy, and fake flex arrays - Improve use of const variables in FORTIFY - Add requested struct_size_t() helper for types not pointers - Add __counted_by macro for annotating flexible array size members" * tag 'hardening-v6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (54 commits) netfilter: ipset: Replace strlcpy with strscpy uml: Replace strlcpy with strscpy um: Use HOST_DIR for mrproper kallsyms: Replace all non-returning strlcpy with strscpy sh: Replace all non-returning strlcpy with strscpy of/flattree: Replace all non-returning strlcpy with strscpy sparc64: Replace all non-returning strlcpy with strscpy Hexagon: Replace all non-returning strlcpy with strscpy kobject: Use return value of strreplace() lib/string_helpers: Change returned value of the strreplace() jbd2: Avoid printing outside the boundary of the buffer checkpatch: Check for 0-length and 1-element arrays riscv/purgatory: Do not use fortified string functions s390/purgatory: Do not use fortified string functions x86/purgatory: Do not use fortified string functions acpi: Replace struct acpi_table_slit 1-element array with flex-array clocksource: Replace all non-returning strlcpy with strscpy string: use __builtin_memcpy() in strlcpy/strlcat staging: most: Replace all non-returning strlcpy with strscpy drm/i2c: tda998x: Replace all non-returning strlcpy with strscpy ...

Core: - submit IO synchronously for fast checksums (crc32c and xxhash), remove high priority worker kthread - read extent buffer in one go, simplify IO tracking, bio submission and locking - remove additional tracking of redirtied extent buffers, originally added for zoned mode but actually not needed - track ordered extent pointer in bio to avoid rbtree lookups during IO - scrub, use recovered data stripes as cache to avoid unnecessary read - in zoned mode, optimize logical to physical mappings of extents - remove PageError handling, not set by VFS nor writeback - cleanups, refactoring, better structure packing - lots of error handling improvements - more assertions, lockdep annotations - print assertion failure with the exact line where it happens - tracepoint updates - more debugging prints Performance: - speedup in fsync(), better tracking of inode logged status can avoid transaction commit - IO path structures track logical offsets in data structures and does not need to look it up User visible changes: - don't commit transaction for every created subvolume, this can reduce time when many subvolumes are created in a batch - print affected files when relocation fails - trigger orphan file cleanup during START_SYNC ioctl Notable fixes: - fix crash when disabling quota and relocation - fix crashes when removing roots from drity list - fix transacion abort during relocation when converting from newer profiles not covered by fallback - in zoned mode, stop reclaiming block groups if filesystem becomes read-only - fix rare race condition in tree mod log rewind that can miss some btree node slots - with enabled fsverity, drop up-to-date page bit in case the verification fails" * tag 'for-6.5-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (194 commits) btrfs: fix race between quota disable and relocation btrfs: add comment to struct btrfs_fs_info::dirty_cowonly_roots btrfs: fix race when deleting free space root from the dirty cow roots list btrfs: fix race when deleting quota root from the dirty cow roots list btrfs: tracepoints: also show actual number of the outstanding extents btrfs: update i_version in update_dev_time btrfs: make btrfs_compressed_bioset static btrfs: add handling for RAID1C23/DUP to btrfs_reduce_alloc_profile btrfs: scrub: remove btrfs_fs_info::scrub_wr_completion_workers btrfs: scrub: remove scrub_ctx::csum_list member btrfs: do not BUG_ON after failure to migrate space during truncation btrfs: do not BUG_ON on failure to get dir index for new snapshot btrfs: send: do not BUG_ON() on unexpected symlink data extent btrfs: do not BUG_ON() when dropping inode items from log root btrfs: replace BUG_ON() at split_item() with proper error handling btrfs: do not BUG_ON() on tree mod log failures at btrfs_del_ptr() btrfs: do not BUG_ON() on tree mod log failures at insert_ptr() btrfs: do not BUG_ON() on tree mod log failure at insert_new_root() btrfs: do not BUG_ON() on tree mod log failures at push_nodes_for_insert() btrfs: abort transaction at update_ref_for_cow() when ref count is zero ...

Due to the fact that TPIDR2 is intended to be managed by libc we don't currently test modifying it via the signal context since that might disrupt libc's usage of it and cause instability. We can however test the opposite case with less risk, modifying TPIDR2 in a signal handler and making sure that the original value is restored after returning from the signal handler. Add a test which does this.

2023-06-22selftests: forwarding: Fix race condition in mirror installationDanielle Ratson2-0/+8
When mirroring to a gretap in hardware the device expects to be programmed with the egress port and all the encapsulating headers. This requires the driver to resolve the path the packet will take in the software data path and program the device accordingly. If the path cannot be resolved (in this case because of an unresolved neighbor), then mirror installation fails until the path is resolved. This results in a race that causes the test to sometimes fail. Fix this by setting the neighbor's state to permanent in a couple of tests, so that it is always valid.

This was asked for to prevent leaks of user events hanging around needing admins to clean them up. - Add persistent logic (but not let user space use it yet) In some cases, having a persistent user event (one that does not get cleaned up automatically) is useful.

A few other uffd*() routines, however, are only used by the uffd-focused tests found in uffd-stress.c and uffd-unit-tests.c. Move those routines into uffd-common.c.

2023-06-20selftests/mm: fix build failures due to missing MADV_COLLAPSEJohn Hubbard3-17/+10
MADV_PAGEOUT, MADV_POPULATE_READ, MADV_COLLAPSE are conditionally defined as necessary. However, that was being done in .c files, and a new build failure came up that would have been automatically avoided had these been in a common header file. So consolidate and move them all to vm_util.h, which fixes the build failure. An alternative approach from Muhammad Usama Anjum was: rely on "make headers" being required, and include asm-generic/mman-common.h. This works in the sense that it builds, but it still generates warnings about duplicate MADV_* symbols, and the goal here is to get a fully clean (no warnings) build here.

2023-06-20selftests/mm: fix two -Wformat-security warnings in uffd buildsJohn Hubbard1-10/+6
The uffd tests generate two compile time warnings from clang's -Wformat-security setting. These trigger at the call sites for uffd_test_start() and uffd_test_skip(). 1) Fix the uffd_test_start() issue by removing the intermediate test_name variable (thanks to David Hildenbrand for showing how to do this). 2) Fix the uffd_test_skip() issue by observing that there is no need for a macro and a variable args approach, because all callers of uffd_test_skip() pass in a simple char* string, without any format specifiers. So just change uffd_test_skip() into a regular C function.

Patch series "A minor flurry of selftest/mm fixes", v3. A series that fixes up build errors and warnings for at least the 64-bit builds on x86 with clang. The series also includes an optional "improvement" of moving some uffd code into uffd-common.[ch], which is proving to be somewhat controversial, and so if that doesn't get resolved, then patches 9 and 10 may just get dropped. They are not required in order to get a clean build, now that "make headers" is happening.

2023-06-19selftests/mm: fix cross compilation with LLVMMark Brown1-5/+8
Currently the MM selftests attempt to work out the target architecture by using CROSS_COMPILE or otherwise querying the host machine, storing the target architecture in a variable called MACHINE rather than the usual ARCH though as far as I can tell (including for x86_64) the value is the same as we would use for architecture. When cross compiling with LLVM we don't need a CROSS_COMPILE as LLVM can support many target architectures in a single build so this logic does not work, CROSS_COMPILE is not set and we end up selecting tests for the host rather than target architecture. Fix this by using the more standard ARCH to describe the architecture, taking it from the environment if specified.
