[PATCH OLK-6.6] bpf: Check size for BTF-based ctx access of pointer members
by Tengda Wu 16 Jan '25

16 Jan '25

From: Kumar Kartikeya Dwivedi <memxor(a)gmail.com> stable inclusion from stable-v6.6.67 commit c7e1962a3807d2a9e8c192f23cd3a55794d08f90 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBHYOV Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 659b9ba7cb2d7adb64618b87ddfaa528a143766e upstream. Robert Morris reported the following program type which passes the verifier in [0]: SEC("struct_ops/bpf_cubic_init") void BPF_PROG(bpf_cubic_init, struct sock *sk) { asm volatile("r2 = *(u16*)(r1 + 0)"); // verifier should demand u64 asm volatile("*(u32 *)(r2 +1504) = 0"); // 1280 in some configs } The second line may or may not work, but the first instruction shouldn't pass, as it's a narrow load into the context structure of the struct ops callback. The code falls back to btf_ctx_access to ensure correctness and obtaining the types of pointers. Ensure that the size of the access is correctly checked to be 8 bytes, otherwise the verifier thinks the narrow load obtained a trusted BTF pointer and will permit loads/stores as it sees fit. Perform the check on size after we've verified that the load is for a pointer field, as for scalar values narrow loads are fine. Access to structs passed as arguments to a BPF program are also treated as scalars, therefore no adjustment is needed in their case. Existing verifier selftests are broken by this change, but because they were incorrect. Verifier tests for d_path were performing narrow load into context to obtain path pointer, had this program actually run it would cause a crash. The same holds for verifier_btf_ctx_access tests.

[PATCH openEuler-1.0-LTS] quota: flush quota_release_work upon quota writeback
by Baokun Li 15 Jan '25

15 Jan '25

From: Ojaswin Mujoo <ojaswin(a)linux.ibm.com> stable inclusion from stable-v5.10.231 commit 6f3821acd7c3143145999248087de5fb4b48cf26 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBHBWQ CVE: CVE-2024-56780 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit ac6f420291b3fee1113f21d612fa88b628afab5b ] One of the paths quota writeback is called from is: freeze_super() sync_filesystem() ext4_sync_fs() dquot_writeback_dquots() Since we currently don't always flush the quota_release_work queue in this path, we can end up with the following race: 1. dquot are added to releasing_dquots list during regular operations. 2. FS Freeze starts, however, this does not flush the quota_release_work queue. 3. Freeze completes. 4. Kernel eventually tries to flush the workqueue while FS is frozen which hits a WARN_ON since transaction gets started during frozen state: ext4_journal_check_start+0x28/0x110 [ext4] (unreliable) __ext4_journal_start_sb+0x64/0x1c0 [ext4] ext4_release_dquot+0x90/0x1d0 [ext4] quota_release_workfn+0x43c/0x4d0 Which is the following line: WARN_ON(sb->s_writers.frozen == SB_FREEZE_COMPLETE); Which ultimately results in generic/390 failing due to dmesg noise. This was detected on powerpc machine 15 cores. To avoid this, make sure to flush the workqueue during dquot_writeback_dquots() so we dont have any pending workitems after freeze.
