b2466bb3 - selftests/mm: introduce uffd-wp-mremap regression test

Tue, 07 Jan 2025 14:47:53 +0000

selftests/mm: introduce uffd-wp-mremap regression testIntroduce a test that registers a range of memory forUFFDIO_WRITEPROTECT_MODE_WP without UFFD_FEATURE_EVENT_REMAP. First checkthat the uffd-wp bit is set for every PTE in the range. Then mremap() therange to a new location and check that the uffd-wp bit is clear for everyPTE in the range.Run the test for small folios, all supported THP sizes and all supportedhugetlb sizes, and for swapped out memory, shared and private.There was previously a bug in the kernel where the uffd-wp bits remainedset in all PTEs for this case, after fixing the kernel, the tests allpass.Link: https://lkml.kernel.org/r/20250107144755.1871363-3-ryan.roberts@arm.comSigned-off-by: Ryan Roberts Cc: David Hildenbrand Cc: Jann Horn Cc: Liam R.

50910acd - selftests/mm: use sys_pkey helpers consistently

Mon, 09 Dec 2024 09:50:16 +0000

selftests/mm: use sys_pkey helpers consistentlysys_pkey_alloc, sys_pkey_free and sys_mprotect_pkey are currently used inprotections_keys.c, while pkey_sighandler_tests.c calls the libc wrappersdirectly (e.g. pkey_mprotect()). This is probably ok when using glibc(those symbols appeared a while ago), but Musl does not currently providethem. The logging in the helpers from pkey-helpers.h can also come inhandy.Make things more consistent by using the sys_pkey helpers inpkey_sighandler_tests.c too. To that end their implementation is moved toa common .c file (pkey_util.c). This also enables callingis_pkeys_supported() outside of protections_keys.c, since it relies onsys_pkey_{alloc,free}.[kevin.brodsky@arm.com: fix dependency on pkey_util.c] Link: https://lkml.kernel.org/r/20241216092849.2140850-1-kevin.brodsky@arm.comLink: https://lkml.kernel.org/r/20241209095019.1732120-12-kevin.brodsky@arm.comSigned-off-by: Kevin Brodsky Cc: Aruna Ramakrishna Cc: Catalin Marinas Cc: Dave Hansen Cc: Joey Gouly Cc: Keith Lucas Cc: Ryan Roberts Cc: Shuah Khan Signed-off-by: Andrew Morton List of files: /linux-6.15/tools/testing/selftests/mm/Makefile

Thu, 22 Aug 2024 15:11:09 +0000

selftests: mm: make protection_keys test work on arm64The encoding of the pkey register differs on arm64, than on x86/ppc. On thoseplatforms, a bit in the register is used to disable permissions, for arm64, abit enabled in the register indicates that the permission is allowed.This drops two asserts of the form: assert(read_pkey_reg() <= orig_pkey_reg);Because on arm64 this doesn't hold, due to the encoding.The pkey must be reset to both access allow and write allow in the signalhandler. pkey_access_allow() works currently for PowerPC as thePKEY_DISABLE_ACCESS and PKEY_DISABLE_WRITE have overlapping bits set.Access to the uc_mcontext is abstracted, as arm64 has a different structure.Signed-off-by: Joey Gouly Cc: Catalin Marinas Cc: Will Deacon Cc: Andrew Morton Cc: Shuah Khan Cc: Dave Hansen Cc: Aneesh Kumar K.V Acked-by: Dave Hansen Link: https://lore.kernel.org/r/20240822151113.1479789-27-joey.gouly@arm.comSigned-off-by: Will Deacon List of files: /linux-6.15/tools/testing/selftests/mm/Makefile

9651fced - mm: add MAP_DROPPABLE for designating always lazily freeable mappings

Thu, 08 Dec 2022 16:55:04 +0000

mm: add MAP_DROPPABLE for designating always lazily freeable mappingsThe vDSO getrandom() implementation works with a buffer allocated with anew system call that has certain requirements:- It shouldn't be written to core dumps. * Easy: VM_DONTDUMP.- It should be zeroed on fork. * Easy: VM_WIPEONFORK.- It shouldn't be written to swap. * Uh-oh: mlock is rlimited. * Uh-oh: mlock isn't inherited by forks.- It shouldn't reserve actual memory, but it also shouldn't crash when page faulting in memory if none is available * Uh-oh: VM_NORESERVE means segfaults.It turns out that the vDSO getrandom() function has three really nicecharacteristics that we can exploit to solve this problem:1) Due to being wiped during fork(), the vDSO code is already robust to having the contents of the pages it reads zeroed out midway through the function's execution.2) In the absolute worst case of whatever contingency we're coding for, we have the option to fallback to the getrandom() syscall, and everything is fine.3) The buffers the function uses are only ever useful for a maximum of 60 seconds -- a sort of cache, rather than a long term allocation.These characteristics mean that we can introduce VM_DROPPABLE, whichhas the following semantics:a) It never is written out to swap.b) Under memory pressure, mm can just drop the pages (so that they're zero when read back again).c) It is inherited by fork.d) It doesn't count against the mlock budget, since nothing is locked.e) If there's not enough memory to service a page fault, it's not fatal, and no signal is sent.This way, allocations used by vDSO getrandom() can use: VM_DROPPABLE | VM_DONTDUMP | VM_WIPEONFORK | VM_NORESERVEAnd there will be no problem with OOMing, crashing on overcommitment,using memory when not in use, not wiping on fork(), coredumps, orwriting out to swap.In order to let vDSO getrandom() use this, expose these via mmap(2) asMAP_DROPPABLE.Note that this involves removing the MADV_FREE special case fromsort_folio(), which according to Yu Zhao is unnecessary and will simplyresult in an extra call to shrink_folio_list() in the worst case. Thechunk removed reenables the swapbacked flag, which we don't want forVM_DROPPABLE, and we can't conditionalize it here because there isn't avma reference available.Finally, the provided self test ensures that this is working as desired.Cc: linux-mm@kvack.orgAcked-by: David Hildenbrand Signed-off-by: Jason A.

selftest: mm: Test if hugepage does not get leaked during __bio_release_pages()Commit 1b151e2435fc ("block: Remove special-casing of compound pages")caused a change in behaviour when releasing the pages if the buffer doesnot start at the beginning of the page. This was because the calculationof the number of pages to release was incorrect. This was fixed by commit38b43539d64b ("block: Fix page refcounts for unaligned buffers in__bio_release_pages()").We pin the user buffer during direct I/O writes. If this buffer is ahugepage, bio_release_page() will unpin it and decrement all referencesand pin counts at ->bi_end_io. However, if any references to the hugepageremain post-I/O, the hugepage will not be freed upon unmap, leading to amemory leak.This patch verifies that a hugepage, used as a user buffer for DIOoperations, is correctly freed upon unmapping, regardless of whether theoffsets are aligned or unaligned w.r.t page boundary.Test Result Fail Scenario (Without the fix)--------------------------------------------------------[]# ./hugetlb_dioTAP version 131..4No. Free pages before allocation : 7No. Free pages after munmap : 7ok 1 : Huge pages freed successfully !No. Free pages before allocation : 7No. Free pages after munmap : 7ok 2 : Huge pages freed successfully !No. Free pages before allocation : 7No. Free pages after munmap : 7ok 3 : Huge pages freed successfully !No. Free pages before allocation : 7No. Free pages after munmap : 6not ok 4 : Huge pages not freed!Totals: pass:3 fail:1 xfail:0 xpass:0 skip:0 error:0Test Result PASS Scenario (With the fix)---------------------------------------------------------[]#./hugetlb_dioTAP version 131..4No. Free pages before allocation : 7No. Free pages after munmap : 7ok 1 : Huge pages freed successfully !No. Free pages before allocation : 7No. Free pages after munmap : 7ok 2 : Huge pages freed successfully !No. Free pages before allocation : 7No. Free pages after munmap : 7ok 3 : Huge pages freed successfully !No. Free pages before allocation : 7No. Free pages after munmap : 7ok 4 : Huge pages freed successfully !Totals: pass:4 fail:0 xfail:0 xpass:0 skip:0 error:0[donettom@linux.ibm.com: address review comments from Muhammad] Link: https://lkml.kernel.org/r/20240604132801.23377-1-donettom@linux.ibm.com[donettom@linux.ibm.com: add this test to run_vmtests.sh] Link: https://lkml.kernel.org/r/20240607182000.6494-1-donettom@linux.ibm.comLink: https://lkml.kernel.org/r/20240523063905.3173-1-donettom@linux.ibm.comFixes: 38b43539d64b ("block: Fix page refcounts for unaligned buffers in __bio_release_pages()")Signed-off-by: Donet Tom Signed-off-by: Ritesh Harjani (IBM) Co-developed-by: Ritesh Harjani (IBM) Reviewed-by: Muhammad Usama Anjum Cc: David Hildenbrand Cc: Matthew Wilcox (Oracle) Cc: Mike Rapoport (IBM) Cc: Muchun Song Cc: Ritesh Harjani (IBM) Cc: Shuah Khan Cc: Tony Battersby Cc: Jens Axboe Signed-off-by: Andrew Morton List of files: /linux-6.15/tools/testing/selftests/mm/Makefile
