cifs: SMB1 split: Split SMB1 protocol defs into smb1pdu.h

2026-02-08T23:07:45+00:00

Split SMB1 protocol defs into smb1pdu.h. This should perhaps go in the common/ directory.

cifs: Do some preparation prior to organising the function declarations

2025-12-05T23:11:55+00:00

Make some preparatory cleanups prior to running a script to organise the function declarations within the fs/smb/client/ headers. These include: (1) Remove "inline" from the dummy cifs_proc_init/clean() functions as they are in a .c file. (2) Move should_compress()'s kdoc comment to the .c file and remove kdoc markers from the comments. (3) Rename CIFS_ALLOW_INSECURE_LEGACY in #endif comments to have CONFIG_ on the front to allow the script to recognise it. (4) Don't let comments have bare words at the left margin as that confused the simplistic function detection code in the script. (5) Adjust some argument lists so that when and if the cleanup script is run they don't end up over 100 chars. (6) Fix a few comments to have missing '*' added or the "*/" moved to their own lines so that checkpatch doesn't moan over the cleanup script patch. (7) Move struct cifs_calc_sig_ctx to cifsglob.h. (8) Remove some __KERNEL__ conditionals. Signed-off-by: David Howells Reviewed-by: Paulo Alcantara (Red Hat) cc: linux-cifs@vger.kernel.org Signed-off-by: Steve French

cifs: Remove the RFC1002 header from smb_hdr

2025-12-05T23:09:32+00:00

Remove the RFC1002 header from struct smb_hdr as used for SMB-1.0. This simplifies the SMB-1.0 code by simplifying a lot of places that have to add or subtract 4 to work around the fact that the RFC1002 header isn't really part of the message and the base for various offsets within the message is from the base of the smb_hdr, not the RFC1002 header. Further, clean up a bunch of places that require an extra kvec struct specifically pointing to the RFC1002 header, such that kvec[0].iov_base must be exactly 4 bytes before kvec[1].iov_base. This allows the header preamble size stuff to be removed too. The size of the request and response message are then handed around either directly or by summing the size of all the iov_len members in the kvec array for which we have a count. Also, this simplifies and cleans up the common transmission and receive paths for SMB1 and SMB2/3 as there no longer needs to be special handling casing for SMB1 messages as the RFC1002 header is now generated on the fly for SMB1 as it is for SMB2/3.

smb: client: account smb directory cache usage and per-tcon totals

2025-10-02T02:49:53+00:00

Add lightweight accounting for directory lease cache usage to aid debugging and limiting cache size in future. Track per-directory entry/byte counts and maintain per-tcon aggregates. Also expose the totals in /proc/fs/cifs/open_dirs. Signed-off-by: Bharath SM Signed-off-by: Steve French

smb: client: show lease state as R/H/W (or NONE) in open_files

smb: client: make use of smbdirect_socket.mr_io

2025-09-28T23:29:50+00:00

Now struct smbd_connection only contains struct smbdirect_socket, this is an important step towards having common functions as well.
