From: James Clark <james.clark(a)arm.com> stable inclusion from stable-v6.6.33 commit 95e33c0f617b436436492d4fd0acdd5c0395071c category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IA74DQ Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 8a55c1e2c9e123b399b272a7db23f09dbb74af21 upstream. It finds all occurrences of a single character and replaces them with a multi character string. This will be used in a test in a following commit.

[PATCH OLK-5.10] NFSD: Fix the behavior of READ near OFFSET_MAX
by Li Lingfeng 07 Aug '24

07 Aug '24

From: Chuck Lever <chuck.lever(a)oracle.com> stable inclusion from stable-v5.10.220 commit 1726a39b0879acfb490b22dca643f26f4f907da9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IADG80 CVE: CVE-2022-48827 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 0cb4d23ae08c48f6bf3c29a8e5c4a74b8388b960 ] Dan Aloni reports: > Due to commit 8cfb9015280d ("NFS: Always provide aligned buffers to > the RPC read layers") on the client, a read of 0xfff is aligned up > to server rsize of 0x1000. > > As a result, in a test where the server has a file of size > 0x7fffffffffffffff, and the client tries to read from the offset > 0x7ffffffffffff000, the read causes loff_t overflow in the server > and it returns an NFS code of EINVAL to the client. The client as > a result indefinitely retries the request. The Linux NFS client does not handle NFS?ERR_INVAL, even though all NFS specifications permit servers to return that status code for a READ. Instead of NFS?ERR_INVAL, have out-of-range READ requests succeed and return a short result. Set the EOF flag in the result to prevent the client from retrying the READ request. This behavior appears to be consistent with Solaris NFS servers. Note that NFSv3 and NFSv4 use u64 offset values on the wire. These must be converted to loff_t internally before use -- an implicit type cast is not adequate for this purpose. Otherwise VFS checks against sb->s_maxbytes do not work properly.
