CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-35784 – btrfs: fix deadlock with fiemap and extent locking
https://notcve.org/view.php?id=CVE-2024-35784
In the Linux kernel, the following vulnerability has been resolved: btrfs: fix deadlock with fiemap and extent locking While working on the patchset to remove extent locking I got a lockdep splat with fiemap and pagefaulting with my new extent lock replacement lock. This deadlock exists with our normal code, we just don't have lockdep annotations with the extent locking so we've never noticed it. Since we're copying the fiemap extent to user space on every iteration we have the chance of pagefaulting. Because we hold the extent lock for the entire range we could mkwrite into a range in the file that we have mmap'ed. This would deadlock with the following stack trace [<0>] lock_extent+0x28d/0x2f0 [<0>] btrfs_page_mkwrite+0x273/0x8a0 [<0>] do_page_mkwrite+0x50/0xb0 [<0>] do_fault+0xc1/0x7b0 [<0>] __handle_mm_fault+0x2fa/0x460 [<0>] handle_mm_fault+0xa4/0x330 [<0>] do_user_addr_fault+0x1f4/0x800 [<0>] exc_page_fault+0x7c/0x1e0 [<0>] asm_exc_page_fault+0x26/0x30 [<0>] rep_movs_alternative+0x33/0x70 [<0>] _copy_to_user+0x49/0x70 [<0>] fiemap_fill_next_extent+0xc8/0x120 [<0>] emit_fiemap_extent+0x4d/0xa0 [<0>] extent_fiemap+0x7f8/0xad0 [<0>] btrfs_fiemap+0x49/0x80 [<0>] __x64_sys_ioctl+0x3e1/0xb50 [<0>] do_syscall_64+0x94/0x1a0 [<0>] entry_SYSCALL_64_after_hwframe+0x6e/0x76 I wrote an fstest to reproduce this deadlock without my replacement lock and verified that the deadlock exists with our existing locking. To fix this simply don't take the extent lock for the entire duration of the fiemap. This is safe in general because we keep track of where we are when we're searching the tree, so if an ordered extent updates in the middle of our fiemap call we'll still emit the correct extents because we know what offset we were on before. The only place we maintain the lock is searching delalloc. Since the delalloc stuff can change during writeback we want to lock the extent range so we have a consistent view of delalloc at the time we're checking to see if we need to set the delalloc flag. With this patch applied we no longer deadlock with my testcase. • https://git.kernel.org/stable/c/ded566b4637f1b6b4c9ba74e7d0b8493e93f19cf https://git.kernel.org/stable/c/89bca7fe6382d61e88c67a0b0e7bce315986fb8b https://git.kernel.org/stable/c/b0ad381fa7690244802aed119b478b4bdafc31dd •

https://notcve.org/view.php?id=CVE-2024-27435
In the Linux kernel, the following vulnerability has been resolved: nvme: fix reconnection fail due to reserved tag allocation We found a issue on production environment while using NVMe over RDMA, admin_q reconnect failed forever while remote target and network is ok. After dig into it, we found it may caused by a ABBA deadlock due to tag allocation. In my case, the tag was hold by a keep alive request waiting inside admin_q, as we quiesced admin_q while reset ctrl, so the request maked as idle and will not process before reset success. As fabric_q shares tagset with admin_q, while reconnect remote target, we need a tag for connect command, but the only one reserved tag was held by keep alive command which waiting inside admin_q. As a result, we failed to reconnect admin_q forever. In order to fix this issue, I think we should keep two reserved tags for admin queue. • https://git.kernel.org/stable/c/ed01fee283a067c72b2d6500046080dbc1bb9dae https://git.kernel.org/stable/c/149afee5c7418ec5db9d7387b9c9a5c1eb7ea2a8 https://git.kernel.org/stable/c/ff2f90f88d78559802466ad1c84ac5bda4416b3a https://git.kernel.org/stable/c/6851778504cdb49431809b4ba061903d5f592c96 https://git.kernel.org/stable/c/262da920896e2f2ab0e3947d9dbee0aa09045818 https://git.kernel.org/stable/c/de105068fead55ed5c07ade75e9c8e7f86a00d1d https://access.redhat.com/security/cve/CVE-2024-27435 https://bugzilla.redhat.com/show_bug.cgi?id=2281131 •
