[PATCH] block: fix use-after-free on cached last_lookup partition
by Yang Yingliang 16 Jan '20

16 Jan '20

From: Yufen Yu <yuyufen(a)huawei.com> hulk inclusion category: bugfix bugzilla: 27962 CVE: NA --------------------------- delete_partition() clears the cached last_lookup partition. However the .last_lookup cache may be overwritten by one IO path after it is cleared from delete_partition(). Then another IO path may use the cached deleting partition after __delete_partition() is called, then use-after-free is triggered on the cached partition. Fixes the issue by the following approach: 1) always get the partition's refcount via hd_struct_try_get() before setting .last_lookup 2) move clearing .last_lookup from delete_partition() to __delete_partition() which is release handle of the partition's percpu-refcount, so that no IO path can overwrite .last_lookup after it is cleared in __delete_partition(). It is one candidate approach of Yufen's patch[1] which adds overhead in fast path by indirect lookup which may introduce one extra cacheline in IO path. Also this patch relies on percpu-refcount's protection, and it is easier to understand and verify.

[PATCH] arm64/sve: Fix missing SVE/FPSIMD endianness conversions
by Yang Yingliang 16 Jan '20

16 Jan '20

From: Dave Martin <Dave.Martin(a)arm.com> mainline inclusion from mainline-5.2-rc5 commit 41040cf7c5f0 category: bugfix bugzilla: 27454 CVE: NA ------------------------------------------------- The in-memory representation of SVE and FPSIMD registers is different: the FPSIMD V-registers are stored as single 128-bit host-endian values, whereas SVE registers are stored in an endianness-invariant byte order. This means that the two representations differ when running on a big-endian host. But we blindly copy data from one representation to another when converting between the two, resulting in the register contents being unintentionally byteswapped in certain situations. Currently this can be triggered by the first SVE instruction after a syscall, for example (though the potential trigger points may vary in future). So, fix the conversion functions fpsimd_to_sve(), sve_to_fpsimd() and sve_sync_from_fpsimd_zeropad() to swab where appropriate. There is no common swahl128() or swab128() that we could use here. Maybe it would be worth making this generic, but for now add a simple local hack. Since the byte order differences are exposed in ABI, also clarify the documentation.
