Title

mm/swap: fix race when skipping swapcache

Summary

In the Linux kernel, the following vulnerability has been resolved: mm/swap: fix race when skipping swapcache When skipping swapcache for SWP_SYNCHRONOUS_IO, if two or more threads swapin the same entry at the same time, they get different pages (A, B). Before one thread (T0) finishes the swapin and installs page (A) to the PTE, another thread (T1) could finish swapin of page (B), swap_free the entry, then swap out the possibly modified page reusing the same entry. It breaks the pte_same check in (T0) because PTE value is unchanged, causing ABA problem. Thread (T0) will install a stalled page (A) into the PTE and cause data corruption. One possible callstack is like this: CPU0 CPU1 ---- ---- do_swap_page() do_swap_page() with same entry <direct swapin path> <direct swapin path> <alloc page A> <alloc page B> swap_read_folio() <- read to page A swap_read_folio() <- read to page B <slow on later locks or interrupt> <finished swapin first> ... set_pte_at() swap_free() <- entry is free <write to page B, now page A stalled> <swap out page B to same swap entry> pte_same() <- Check pass, PTE seems unchanged, but page A is stalled! swap_free() <- page B content lost! set_pte_at() <- staled page A installed! And besides, for ZRAM, swap_free() allows the swap device to discard the entry content, so even if page (B) is not modified, if swap_read_folio() on CPU0 happens later than swap_free() on CPU1, it may also cause data loss. To fix this, reuse swapcache_prepare which will pin the swap entry using the cache flag, and allow only one thread to swap it in, also prevent any parallel code from putting the entry in the cache. Release the pin after PT unlocked. Racers just loop and wait since it's a rare and very short event. A schedule_timeout_uninterruptible(1) call is added to avoid repeated page faults wasting too much CPU, causing livelock or adding too much noise to perf statistics. A similar livelock issue was described in commit 029c4628b2eb ("mm: swap: get rid of livelock in swapin readahead") Reproducer: This race issue can be triggered easily using a well constructed reproducer and patched brd (with a delay in read path) [1]: With latest 6.8 mainline, race caused data loss can be observed easily: $ gcc -g -lpthread test-thread-swap-race.c && ./a.out Polulating 32MB of memory region... Keep swapping out... Starting round 0... Spawning 65536 workers... 32746 workers spawned, wait for done... Round 0: Error on 0x5aa00, expected 32746, got 32743, 3 data loss! Round 0: Error on 0x395200, expected 32746, got 32743, 3 data loss! Round 0: Error on 0x3fd000, expected 32746, got 32737, 9 data loss! Round 0 Failed, 15 data loss! This reproducer spawns multiple threads sharing the same memory region using a small swap device. Every two threads updates mapped pages one by one in opposite direction trying to create a race, with one dedicated thread keep swapping out the data out using madvise. The reproducer created a reproduce rate of about once every 5 minutes, so the race should be totally possible in production. After this patch, I ran the reproducer for over a few hundred rounds and no data loss observed. Performance overhead is minimal, microbenchmark swapin 10G from 32G zram: Before: 10934698 us After: 11157121 us Cached: 13155355 us (Dropping SWP_SYNCHRONOUS_IO flag) [kasong@tencent.com: v4]

Release the pin after\nPT unlocked.\n\nRacers just loop and wait since it\u0027s a rare and very short event.  A\nschedule_timeout_uninterruptible(1) call is added to avoid repeated page\nfaults wasting too much CPU, causing livelock or adding too much noise to\nperf statistics.  A similar livelock issue was described in commit\n029c4628b2eb (\"mm: swap: get rid of livelock in swapin readahead\")\n\nReproducer:\n\nThis race issue can be triggered easily using a well constructed\nreproducer and patched brd (with a delay in read path) [1]:\n\nWith latest 6.8 mainline, race caused data loss can be observed easily:\n$ gcc -g -lpthread test-thread-swap-race.c \u0026\u0026 ./a.out\n  Polulating 32MB of memory region...\n  Keep swapping out...\n  Starting round 0...\n  Spawning 65536 workers...\n  32746 workers spawned, wait for done...\n  Round 0: Error on 0x5aa00, expected 32746, got 32743, 3 data loss!\n  Round 0: Error on 0x395200, expected 32746, got 32743, 3 data loss!\n  Round 0: Error on 0x3fd000, expected 32746, got 32737, 9 data loss!\n  Round 0 Failed, 15 data loss!\n\nThis reproducer spawns multiple threads sharing the same memory region\nusing a small swap device.  Every two threads updates mapped pages one by\none in opposite direction trying to create a race, with one dedicated\nthread keep swapping out the data out using madvise.\n\nThe reproducer created a reproduce rate of about once every 5 minutes, so\nthe race should be totally possible in production.\n\nAfter this patch, I ran the reproducer for over a few hundred rounds and\nno data loss observed.\n\nPerformance overhead is minimal, microbenchmark swapin 10G from 32G\nzram:\n\nBefore:     10934698 us\nAfter:      11157121 us\nCached:     13155355 us (Dropping SWP_SYNCHRONOUS_IO flag)\n\n[kasong@tencent.com: v4]"
