smb: add common SMB2 compression transform helpers

2026-06-16T23:57:21+00:00

Implement common validation, compression and decompression for SMB2 compression transforms. Support unchained LZ77 and chained NONE, LZ77 and Pattern_V1 payloads. Signed-off-by: Namjae Jeon Signed-off-by: Steve French

smb: move LZ77 compression into common code

2026-06-16T23:57:21+00:00

Move the LZ77 codec in cifs.ko to smb/common/ so both the SMB client and ksmbd can use it. Signed-off-by: Namjae Jeon Signed-off-by: Steve French

smb/server: implement FSCTL_SET_COMPRESSION ioctl handler

2026-06-16T23:57:21+00:00

Example: 1. client: smbinfo setcompression no /mnt/file 2. client: smbinfo getcompression /mnt/file Compression: 0 (NONE) 3. client: smbinfo setcompression lznt1 /mnt/file 4. client: smbinfo getcompression /mnt/file Compression: 2 (LZNT1) 5. client: smbinfo setcompression default /mnt/file 6. client: smbinfo getcompression /mnt/file Compression: 2 (LZNT1) Signed-off-by: ChenXiaoSong Acked-by: Namjae Jeon Signed-off-by: Steve French

smb/server: implement FSCTL_GET_COMPRESSION ioctl handler

2026-06-16T23:57:21+00:00

Example: 1. server: chattr +c /export/file 2. client: smbinfo getcompression /mnt/file Compression: 2 (LZNT1) Signed-off-by: ChenXiaoSong Acked-by: Namjae Jeon Signed-off-by: Steve French

smb: move compression definitions into common/fscc.h

2026-06-16T23:57:21+00:00

These definitions will also be used by ksmbd, move them into common header file. Signed-off-by: ChenXiaoSong Acked-by: Namjae Jeon Signed-off-by: Steve French

smb: remove duplicate server/smbfsctl.h

2026-06-16T23:57:21+00:00

Rename the following places: - FSCTL_COPYCHUNK -> FSCTL_SRV_COPYCHUNK - FSCTL_COPYCHUNK_WRITE -> FSCTL_SRV_COPYCHUNK_WRITE - FSCTL_REQUEST_RESUME_KEY -> FSCTL_SRV_REQUEST_RESUME_KEY server/smbfsctl.h contains the following additional definitions compared to common/smbfsctl.h: - IO_REPARSE_TAG_LX_SYMLINK_LE - IO_REPARSE_TAG_AF_UNIX_LE - IO_REPARSE_TAG_LX_FIFO_LE - IO_REPARSE_TAG_LX_CHR_LE - IO_REPARSE_TAG_LX_BLK_LE Signed-off-by: ChenXiaoSong Acked-by: Namjae Jeon Signed-off-by: Steve French
