292a089 | Steven Rostedt (Google) | 20 December 2022, 18:45:19 UTC | treewide: Convert del_timer*() to timer_shutdown*() Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed. The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case. This was created by using a coccinelle script and the following commands: $ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); ) $ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/ Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Pavel Machek <pavel@ucw.cz> [ LED ] Acked-by: Kalle Valo <kvalo@kernel.org> [ wireless ] Acked-by: Paolo Abeni <pabeni@redhat.com> [ networking ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> | 25 December 2022, 21:38:09 UTC |

beca3e3 | Luca Stefani | 22 December 2022, 13:10:49 UTC | pstore: Properly assign mem_type property If mem-type is specified in the device tree it would end up overriding the record_size field instead of populating mem_type. As record_size is currently parsed after the improper assignment with default size 0 it continued to work as expected regardless of the value found in the device tree. Simply changing the target field of the struct is enough to get mem-type working as expected.

2f4fec5 | John Stultz | 21 December 2022, 05:18:55 UTC | pstore: Make sure CONFIG_PSTORE_PMSG selects CONFIG_RT_MUTEXES In commit 76d62f24db07 ("pstore: Switch pmsg_lock to an rt_mutex to avoid priority inversion") I changed a lock to an rt_mutex. However, its possible that CONFIG_RT_MUTEXES is not enabled, which then results in a build failure, as the 0day bot detected: https://lore.kernel.org/linux-mm/202212211244.TwzWZD3H-lkp@intel.com/ Thus this patch changes CONFIG_PSTORE_PMSG to select CONFIG_RT_MUTEXES, which ensures the build will not fail.

cf80164 | Sami Tolvanen | 22 December 2022, 22:57:47 UTC | cfi: Fix CFI failure with KASAN When CFI_CLANG and KASAN are both enabled, LLVM doesn't generate a CFI type hash for asan.module_ctor functions in translation units where CFI is disabled, which leads to a CFI failure during boot when do_ctors calls the affected constructors: CFI failure at do_basic_setup+0x64/0x90 (target: asan.module_ctor+0x0/0x28; expected type: 0xa540670c) Specifically, this happens because CFI is disabled for kernel/cfi.c. There's no reason to keep CFI disabled here anymore, so fix the failure by not filtering out CC_FLAGS_CFI for the file. Note that https://reviews.llvm.org/rG3b14862f0a96 fixed the issue where LLVM didn't emit CFI type hashes for any sanitizer constructors, but now type hashes are emitted correctly for TUs that use CFI.

a9eb558 | David Howells | 18 November 2022, 07:57:27 UTC | afs: Stop implementing ->writepage() We're trying to get rid of the ->writepage() hook[1]. Stop afs from using it by unlocking the page and calling afs_writepages_region() rather than folio_write_one(). A flag is passed to afs_writepages_region() to indicate that it should only write a single region so that we don't flush the entire file in ->write_begin(), but do add other dirty data to the region being written to try and reduce the number of RPC ops. This requires ->migrate_folio() to be implemented, so point that at filemap_migrate_folio() for files and also for symlinks and directories. This can be tested by turning on the afs_folio_dirty tracepoint and then doing something like: xfs_io -c "w 2223 7000" -c "w 15000 22222" -c "w 23 7" /afs/my/test/foo and then looking in the trace to see if the write at position 15000 gets stored before page 0 gets dirtied for the write at position 23.

36f82c9 | David Howells | 21 December 2022, 14:30:48 UTC | afs: Fix lost servers_outstanding count The afs_fs_probe_dispatcher() work function is passed a count on net->servers_outstanding when it is scheduled (which may come via its timer). This is passed back to the work_item, passed to the timer or dropped at the end of the dispatcher function. But, at the top of the dispatcher function, there are two checks which skip the rest of the function: if the network namespace is being destroyed or if there are no fileservers to probe. These two return paths, however, do not drop the count passed to the dispatcher, and so, sometimes, the destruction of a network namespace, such as induced by rmmod of the kafs module, may get stuck in afs_purge_servers(), waiting for net->servers_outstanding to become zero. Fix this by adding the missing decrements in afs_fs_probe_dispatcher().

This patchset adds the fix and a test case to the maple tree test suite. This patch (of 2): An insufficient node was causing an out-of-bounds access on the node in mas_leaf_max_gap(). The cause was the faulty detection of the new node being a root node when overwriting many entries at the end of the tree.

However, it left the functional version of helper routines behind #ifdef CONFIG_ARCH_WANT_HUGE_PMD_SHARE. Therefore, the vma lock is not being used for sharable vmas on architectures that do not support pmd sharing. On these architectures, a potential fault/truncation race is exposed that could leave pages in a hugetlb file past i_size until the file is removed.

6f12be7 | Vlastimil Babka | 16 December 2022, 16:32:27 UTC | mm, mremap: fix mremap() expanding vma with addr inside vma Since 6.1 we have noticed random rpm install failures that were tracked to mremap() returning -ENOMEM and to commit ca3d76b0aa80 ("mm: add merging after mremap resize"). The problem occurs when mremap() expands a VMA in place, but using an starting address that's not vma->vm_start, but somewhere in the middle. The extension_pgoff calculation introduced by the commit is wrong in that case, so vma_merge() fails due to pgoffs not being compatible. Fix the calculation. By the way it seems that the situations, where rpm now expands a vma from the middle, were made possible also due to that commit, thanks to the improved vma merging. Yet it should work just fine, except for the buggy calculation.

9854e7a | Hans-Peter Nilsson | 28 December 2020, 02:41:59 UTC | perf arm64: Simplify mksyscalltbl This patch isn't intended to have any effect on the compiled code. It just removes one level of indirection: calling the *host* compiler to build and then run a program that just printf:s the numerical entries of the syscall-table. In other words, the generated syscalls.c changes from: [46] = "ftruncate", to: [__NR3264_ftruncate] = "ftruncate", The latter is as good as the former to the user of perf, and this can be done directly by the shell-script. The syscalls defined as non-literal values (like "#define __NR_ftruncate __NR3264_ftruncate") are trivially resolved at compile-time without namespace-leaking and/or collision for its sole user, perf/util/syscalltbl.c, that just #includes the generated file. A future "-mabi=32" support would probably have to handle this differently, but that is a pre-existing problem not affected by this simplification. Calling the *host* compiler only complicates things and accidentally can get a completely wrong set of files and syscall numbers, see earlier commits. Note that the script parameter hostcc is now unused. At the time of this patch, powerpc (the origin, see comments), and also e.g. x86 has moved on, from filtering "gcc -dM -E" output to reading separate specific text-file, a table of syscall numbers. IMHO should arm64 consider adopting this.

ec222d7 | Namhyung Kim | 15 December 2022, 19:28:15 UTC | perf hist: Improve srcline sort key performance The sort_entry->cmp() will be called for eventy sample data to find a matching entry. When it has 'srcline' sort key, that means it needs to call addr2line or libbfd everytime. This is not optimal because many samples will have same address and it just can call addr2line once. So postpone the actual srcline check to the sort_entry->collpase() and compare addresses in ->cmp(). Also it needs to add ->init() callback to make sure it has srcline info. If a sample has a unique data, chances are the entry can be sorted out by other (previous) keys and callbacks in sort_srcline never called.
