The UML function names to_virt() and to_phys() are exposed by UML headers, and are very generic and may be defined by drivers. As it turns out, commit 9409c9b6 ("pmem: refactor pmem_clear_poison()") did exactly that. This results in build errors such as the following when trying to build um:allmodconfig: drivers/nvdimm/pmem.c: In function ‘pmem_dax_zero_page_range’: ./arch/um/include/asm/page.h:105:20: error: too few arguments to function ‘to_phys’ 105 | #define __pa(virt) to_phys((void *) (unsigned long) (virt)) | ^~~~~~~ Use less generic function names for the um specific to_phys() and to_virt() functions to fix the problem and to avoid similar problems in the future.

The DRM_AMD_DC_DCN display engine support (Raven, Navi, and newer) has not been building cleanly on powerpc and causes link errors due to mixing hard- and soft-float object files: powerpc64-linux-ld: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o uses soft float powerpc64-linux-ld: failed to merge target specific data of file drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o [..] and while patches are floating around, it's not exactly obvious what is going on. The problem bisects to commit 41b7a347 ("powerpc: Book3S 64-bit outline-only KASAN support") but that is probably more about changing config variables than the fundamental cause. Despite the bisection result, a more directly related commit seems to be 26f4712a ("drm/amd/display: move FPU related code from dcn31 to dml/dcn31 folder"). It's probably a combination of the two. This has been going on since the merge window, without any final word. So instead of blindly applying patches that may or may not be the right thing, let's disable this for now. As Michael Ellerman says: "IIUIC this code was never enabled on ppc before, so disabling it seems like a reasonable fix to get the build clean" and once we have more actual feedback (and find any potential users) we can always re-enable it with the patch that fixes the issues and back-port as necessary.

LKP reports a build issue on Clang, related to a literal load of __current issued through the ldr_va macro. This turns out to be due to the fact that group relocations are disabled when CONFIG_COMPILE_TEST=y, which means that the ldr_va macro resolves to a pair of LDR instructions, the first one being a literal load issued too far from its literal pool. Due to the introduction of a couple of new uses of this macro in commit 50807460 ("ARM: 9195/1: entry: avoid explicit literal loads"), the literal pools end up getting rearranged in a way that causes the literal for __current to go out of range. Let's fix this up by putting a .ltorg directive in a suitable place in the code.

If dedupe of an EOF block is not constrainted to match against only other EOF blocks with the same EOF offset into the block, it can match against any other block that has the same matching initial bytes in it, even if the bytes beyond EOF in the source file do not match. Fix this by constraining the EOF block matching to only match against other EOF blocks that have identical EOF offsets and data. This allows "whole file dedupe" to continue to work without allowing eof blocks to randomly match against partial full blocks with the same data. Reported-by:

It was brought up that on ARMv7, that because the FUNCTION_TRACER does not use nops to keep function tracing disabled because of the use of a link register, it does have some performance impact. The start of functions when -pg is used to compile the kernel is: push {lr} bl 8010e7c0 <__gnu_mcount_nc> When function tracing is tuned off, it becomes: push {lr} add sp, sp, #4 Which just puts the stack back to its normal location. But these two instructions at the start of every function does incur some overhead. Be more honest in the Kconfig FUNCTION_TRACER description and specify that the overhead being in the noise was x86 specific, but other architectures may vary.

If you drop into kdb and type "ftdump" you'll get a sleeping while atomic warning from memory allocation in trace_find_next_entry(). This appears to have been caused by commit ff895103 ("tracing: Save off entry when peeking at next entry"), which added the allocation in that path. The problematic commit was already fixed by commit 8e99cf91 ("tracing: Do not allocate buffer in trace_find_next_entry() in atomic") but that fix missed the kdb case. The fix here is easy: just move the assignment of the static buffer to the place where it should have been to begin with: trace_init_global_iter(). That function is called in two places, once is right before the assignment of the static buffer added by the previous fix and once is in kdb. Note that it appears that there's a second static buffer that we need to assign that was added in commit efbbdaa2 ("tracing: Show real address for trace event arguments"), so we'll move that too.

This reverts commit 46bbe5c6. As commit 46bbe5c6 ("tracing: fix double free") said, the "double free" problem reported by clang static analyzer is: > In parse_var_defs() if there is a problem allocating > var_defs.expr, the earlier var_defs.name is freed. > This free is duplicated by free_var_defs() which frees > the rest of the list. However, if there is a problem allocating N-th var_defs.expr: + in parse_var_defs(), the freed 'earlier var_defs.name' is actually the N-th var_defs.name; + then in free_var_defs(), the names from 0th to (N-1)-th are freed; IF ALLOCATING PROBLEM HAPPENED HERE!!! -+ \ | 0th 1th (N-1)-th N-th V +-------------+-------------+-----+-------------+----------- var_defs: | name | expr | name | expr | ... | name | expr | name | /// +-------------+-------------+-----+-------------+----------- These two frees don't act on same name, so there was no "double free" problem before. Conversely, after that commit, we get a "memory leak" problem because the above "N-th var_defs.name" is not freed. If enable CONFIG_DEBUG_KMEMLEAK and inject a fault at where the N-th var_defs.expr allocated, then execute on shell like: $ echo 'hist:key=call_site:val=$v1,$v2:v1=bytes_req,v2=bytes_alloc' > \ /sys/kernel/debug/tracing/events/kmem/kmalloc/trigger Then kmemleak reports: unreferenced object 0xffff8fb100ef3518 (size 8): comm "bash", pid 196, jiffies 4295681690 (age 28.538s) hex dump (first 8 bytes): 76 31 00 00 b1 8f ff ff v1...... backtrace: [<0000000038fe4895>] kstrdup+0x2d/0x60 [<00000000c99c049a>] event_hist_trigger_parse+0x206f/0x20e0 [<00000000ae70d2cc>] trigger_process_regex+0xc0/0x110 [<0000000066737a4c>] event_trigger_write+0x75/0xd0 [<000000007341e40c>] vfs_write+0xbb/0x2a0 [<0000000087fde4c2>] ksys_write+0x59/0xd0 [<00000000581e9cdf>] do_syscall_64+0x3a/0x80 [<00000000cf3b065c>] entry_SYSCALL_64_after_hwframe+0x46/0xb0 Link: https://lkml.kernel.org/r/20220711014731.69520-1-zhengyejian1@huawei.com Cc: stable@vger.kernel.org Fixes: 46bbe5c6 ("tracing: fix double free") Reported-by:

Pull btrfs fixes from David Sterba: "A more fixes that seem to me to be important enough to get merged before release: - in zoned mode, fix leak of a structure when reading zone info, this happens on normal path so this can be significant - in zoned mode, revert an optimization added in 5.19-rc1 to finish a zone when the capacity is full, but this is not reliable in all cases - try to avoid short reads for compressed data or inline files when it's a NOWAIT read, applications should handle that but there are two, qemu and mariadb, that are affected" * tag 'for-5.19-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: btrfs: zoned: drop optimization of zone finish btrfs: zoned: fix a leaked bioc in read_zone_info btrfs: return -EAGAIN for NOWAIT dio reads/writes on compressed and inline extents -

This loop condition tries a bit too hard to be clever. Just test for the two indices we care about explicitly. Cc: J. Bruce Fields <bfields@fieldses.org> Fixes: 7f024fcd ("Keep read and write fds with each nlm_file") Signed-off-by:

Pull module fixes from Luis Chamberlain: "Although most of the move of code in in v5.19-rc1 should have not introduced a regression patch review on one of the file changes captured a checkpatch warning which advised to use strscpy() and it caused a buffer overflow when an incorrect length is passed. Another change which checkpatch complained about was an odd RCU usage, but that was properly addressed in a separate patch to the move by Aaron. That caused a regression with PREEMPT_RT=y due to an unbounded latency. This series fixes both and adjusts documentation which we forgot to do for the move" * tag 'modules-5.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: module: kallsyms: Ensure preemption in add_kallsyms() with PREEMPT_RT doc: module: update file references module: Fix "warning: variable 'exit' set but not used" module: Fix selfAssignment cppcheck warning modules: Fix corruption of /proc/kallsyms

NFSD has advertised support for the NFSv4 time_create attribute since commit e377a3e6 ("nfsd: Add support for the birth time attribute"). Igor Mammedov reports that Mac OS clients attempt to set the NFSv4 birth time attribute via OPEN(CREATE) and SETATTR if the server indicates that it supports it, but since the above commit was merged, those attempts now fail. Table 5 in RFC 8881 lists the time_create attribute as one that can be both set and retrieved, but the above commit did not add server support for clients to provide a time_create attribute. IMO that's a bug in our implementation of the NFSv4 protocol, which this commit addresses. Whether NFSD silently ignores the new birth time or actually sets it is another matter. I haven't found another filesystem service in the Linux kernel that enables users or clients to modify a file's birth time attribute. This commit reflects my (perhaps incorrect) understanding of whether Linux users can set a file's birth time. NFSD will now recognize a time_create attribute but it ignores its value. It clears the time_create bit in the returned attribute bitmask to indicate that the value was not used. Reported-by:
