client MUST ignore EncryptionKeyLength if CAP_EXTENDED_SECURITY is set

[MS-SMB] 2.2.4.5.2.1 states: "ChallengeLength (1 byte): When the CAP_EXTENDED_SECURITY bit is set, the server MUST set this value to zero and clients MUST ignore this value." Signed-off-by: Noel Power Signed-off-by: Steve French

CIFS: remove an unneeded NULL check

2015-05-20T16:36:16+00:00

Smatch complains because we dereference "ses->server" without checking some lines earlier inside the call to get_next_mid(ses->server). fs/cifs/cifssmb.c:4921 CIFSGetDFSRefer() warn: variable dereferenced before check 'ses->server' (see line 4899) There is only one caller for this function get_dfs_path() and it always passes a non-null "ses->server" pointer so this NULL check can be removed.

Remap reserved posix characters by default (part 3/3)

2014-10-16T20:20:20+00:00

This is a bigger patch, but its size is mostly due to a single change for how we check for remapping illegal characters in file names - a lot of repeated, small changes to the way callers request converting file names. The final patch in the series does the following: 1) changes default behavior for cifs to be more intuitive. Currently we do not map by default to seven reserved characters, ie those valid in POSIX but not in NTFS/CIFS/SMB3/Windows, unless a mount option (mapchars) is specified. Change this to by default always map and map using the SFM maping (like the Mac uses) unless the server negotiates the CIFS Unix Extensions (like Samba does when mounting with the cifs protocol) when the remapping of the characters is unnecessary. This should help SMB3 mounts in particular since Samba will likely be able to implement this mapping with its new "vfs_fruit" module as it will be doing for the Mac. 2) if the user specifies the existing "mapchars" mount option then use the "SFU" (Microsoft Services for Unix, SUA) style mapping of the seven characters instead. 3) if the user specifies "nomapposix" then disable SFM/MAC style mapping (so no character remapping would be used unless the user specifies "mapchars" on mount as well, as above). 4) change all the places in the code that check for the superblock flag on the mount which is set by mapchars and passed in on all path based operation and change it to use a small function call instead to set the mapping type properly (and check for the mapping type in the cifs unicode functions) Signed-off-by: Steve French

CIFS: Optimize cifs_user_read() in a short read case on reconnects

CIFS: Fix wsize usage in iovec write

2014-08-02T06:23:02+00:00

If a server change maximum buffer size for write (wsize) requests on reconnect we can fail on repeating with a big size buffer on -EAGAIN error in iovec write. Fix this by checking wsize all the time before repeating request in iovec write. Reviewed-by: Shirish Pargaonkar Signed-off-by: Pavel Shilovsky Signed-off-by: Steve French
