ksmbd: Compare MACs in constant time

2026-03-19T15:08:50Z

commit c5794709bc9105935dbedef8b9cf9c06f2b559fa upstream. To prevent timing attacks, MAC comparisons need to be constant-time. Replace the memcmp() with the correct function, crypto_memneq().

smb: Use arc4 library instead of duplicate arc4 code

2025-09-30T02:21:23Z

fs/smb/common/cifs_arc4.c has an implementation of ARC4, but a copy of this same code is also present in lib/crypto/arc4.c to serve the other users of this legacy algorithm in the kernel. Remove the duplicate implementation in fs/smb/, which seems to have been added because of a misunderstanding, and just use the lib/crypto/ one.

ksmbd: use SHA-256 library API instead of crypto_shash API

2025-05-26T03:54:50Z

ksmbd_gen_sd_hash() does not support any other algorithm, so the crypto_shash abstraction provides no value. Just use the SHA-256 library API instead, which is much simpler and easier to use. Signed-off-by: Eric Biggers Acked-by: Namjae Jeon Signed-off-by: Steve French

fs/smb: Swing unicode common code from smb->NLS

2023-08-30T13:55:51Z

Swing most of the inline functions and unicode tables into nls from the copy in smb/server. This is UCS-2 rather than most of the rest of the code in NLS, but it currently seems like the best place for it. The actual unicode.c implementations vary much more between server and client so they're unmoved. Signed-off-by: Dr. David Alan Gilbert Reviewed-by: Dave Kleikamp Signed-off-by: Steve French

smb: move client and server files to common directory fs/smb

2023-05-24T21:29:21Z

Move CIFS/SMB3 related client and server files (cifs.ko and ksmbd.ko and helper modules) to new fs/smb subdirectory: fs/cifs --> fs/smb/client fs/ksmbd --> fs/smb/server fs/smbfs_common --> fs/smb/common Suggested-by: Linus Torvalds Acked-by: Namjae Jeon Signed-off-by: Steve French
