2023-11-23smb: client: introduce cifs_sfu_make_node()Paulo Alcantara1-72/+8
Remove duplicate code and add new helper for creating special files in SFU (Services for UNIX) format that can be shared by SMB1+ code. Signed-off-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2023-11-23smb: client: set correct file type from NFS reparse pointsPaulo Alcantara1-2/+1
Handle all file types in NFS reparse points as specified in MS-FSCC 2.1.2.6 Network File System (NFS) Reparse Data Buffer. The client is now able to set all file types based on the parsed NFS reparse point, which used to support only symlinks. This works for SMB1+. Before patch: $ mount.cifs //srv/share /mnt -o ... $ ls -l /mnt ls: cannot access 'block': Operation not supported ls: cannot access 'char': Operation not supported ls: cannot access 'fifo': Operation not supported ls: cannot access 'sock': Operation not supported total 1 l????????? ? ? ? ? ? block l????????? ? ? ? ? ? char -rwxr-xr-x 1 root root 5 Nov 18 23:22 f0 l????????? ? ? ? ? ? fifo l--------- 1 root root 0 Nov 18 23:23 link -> f0 l????????? ? ? ? ? ? sock After patch: $ mount.cifs //srv/share /mnt -o ... $ ls -l /mnt total 1 brwxr-xr-x 1 root root 123, 123 Nov 18 00:34 block crwxr-xr-x 1 root root 1234, 1234 Nov 18 00:33 char -rwxr-xr-x 1 root root 5 Nov 18 23:22 f0 prwxr-xr-x 1 root root 0 Nov 18 23:23 fifo lrwxr-xr-x 1 root root 0 Nov 18 23:23 link -> f0 srwxr-xr-x 1 root root 0 Nov 19 2023 sock Signed-off-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2023-11-23smb: client: introduce ->parse_reparse_point()Paulo Alcantara1-18/+23
Parse reparse point into cifs_open_info_data structure and feed it through cifs_open_info_to_fattr(). Signed-off-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2023-11-23smb: client: implement ->query_reparse_point() for SMB1Paulo Alcantara1-39/+10
Reparse points are not limited to symlinks, so implement ->query_reparse_point() in order to handle different file types. Signed-off-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2023-08-21smb: client: do not query reparse points twice on symlinksPaulo Alcantara1-4/+7
Save a roundtrip by getting the reparse point tag and buffer at once in ->query_reparse_point() and then pass the buffer down to ->query_symlink(). Signed-off-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2023-08-21smb: client: move some params to cifs_open_info_dataPaulo Alcantara1-6/+9
Instead of passing @adjust_tz and some reparse point related fields as parameters in ->query_path_info() and {smb311_posix,cifs}_info_to_fattr() calls, move them to cifs_open_info_data structure as they can be easily accessed through @data. No functional changes. Signed-off-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2023-05-25smb: move client and server files to common directory fs/smbSteve French1-0/+1276
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 <torvalds@linux-foundation.org> Acked-by: Namjae Jeon <linkinjeon@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>
