filesystems: add missing nlink wrappers

2011-11-02T11:53:43Z

Replace direct i_nlink updates with the respective updater function (inc_nlink, drop_nlink, clear_nlink, inode_dec_link_count). Signed-off-by: Miklos Szeredi

cifs: Add mount options for backup intent (try #6)

2011-10-13T04:42:17Z

Add mount options backupuid and backugid. It allows an authenticated user to access files with the intent to back them up including their ACLs, who may not have access permission but has "Backup files and directories user right" on them (by virtue of being part of the built-in group Backup Operators. When mount options backupuid is specified, cifs client restricts the use of backup intents to the user whose effective user id is specified along with the mount option. When mount options backupgid is specified, cifs client restricts the use of backup intents to the users whose effective user id belongs to the group id specified along with the mount option. If an authenticated user is not part of the built-in group Backup Operators at the server, access to such files is denied, even if allowed by the client.

[CIFS] Rename three structures to avoid camel case

CIFS: Add rwpidforward mount option

2011-05-27T03:57:16Z

Add rwpidforward mount option that switches on a mode when we forward pid of a process who opened a file to any read and write operation. This can prevent applications like WINE from failing on read or write operation on a previously locked file region from the same netfd from another process if we use mandatory brlock style. It is actual for WINE because during a run of WINE program two processes work on the same netfd - share the same file struct between several VFS fds: 1) WINE-server does open and lock; 2) WINE-application does read and write.

CIFS: Use pid saved from cifsFileInfo in writepages and set_file_size

2011-05-26T18:07:02Z

We need it to make them work with mandatory locking style because we can fail in a situation like when kernel need to flush dirty pages and there is a lock held by a process who opened file. Signed-off-by: Pavel Shilovsky Signed-off-by: Steve French

various endian fixes to cifs

make modules C=2 M=fs/cifs CF=-D__CHECK_ENDIAN__ Found for example: CHECK fs/cifs/cifssmb.c fs/cifs/cifssmb.c:728:22: warning: incorrect type in assignment (different base types) fs/cifs/cifssmb.c:728:22: expected unsigned short [unsigned] [usertype] Tid fs/cifs/cifssmb.c:728:22: got restricted __le16 [usertype] fs/cifs/cifssmb.c:1883:45: warning: incorrect type in assignment (different base types) fs/cifs/cifssmb.c:1883:45: expected long long [signed] [usertype] fl_start fs/cifs/cifssmb.c:1883:45: got restricted __le64 [usertype] start fs/cifs/cifssmb.c:1884:54: warning: restricted __le64 degrades to integer fs/cifs/cifssmb.c:1885:58: warning: restricted __le64 degrades to integer fs/cifs/cifssmb.c:1886:43: warning: incorrect type in assignment (different base types) fs/cifs/cifssmb.c:1886:43: expected unsigned int [unsigned] fl_pid fs/cifs/cifssmb.c:1886:43: got restricted __le32 [usertype] pid In checking new smb2 code for missing endian conversions, I noticed some endian errors had crept in over the last few releases into the cifs code (symlink, ntlmssp, posix lock, and also a less problematic warning in fscache). A followon patch will address a few smb2 endian problems. Reviewed-by: Jeff Layton Signed-off-by: Steve French

cifs: More crypto cleanup (try #2)

2011-01-27T19:58:13Z

Replaced md4 hashing function local to cifs module with kernel crypto APIs. As a result, md4 hashing function and its supporting functions in file md4.c are not needed anymore. Cleaned up function declarations, removed forward function declarations, and removed a header file that is being deleted from being included. Verified that sec=ntlm/i, sec=ntlmv2/i, and sec=ntlmssp/i work correctly. Signed-off-by: Shirish Pargaonkar Reviewed-by: Jeff Layton Signed-off-by: Steve French
