2011-09-20cifs: Fix broken sec=ntlmv2/i sec option (try #2)Shirish Pargaonkar1-43/+11
Fix sec=ntlmv2/i authentication option during mount of Samba shares. cifs client was coding ntlmv2 response incorrectly. All that is needed in temp as specified in MS-NLMP seciton 3.3.2 "Define ComputeResponse(NegFlg, ResponseKeyNT, ResponseKeyLM, CHALLENGE_MESSAGE.ServerChallenge, ClientChallenge, Time, ServerName) as Set temp to ConcatenationOf(Responserversion, HiResponserversion, Z(6), Time, ClientChallenge, Z(4), ServerName, Z(4)" is MsvAvNbDomainName. For sec=ntlmsspi, build_av_pair is not used, a blob is plucked from type 2 response sent by the server to use in authentication. I tested sec=ntlmv2/i and sec=ntlmssp/i mount options against Samba (3.6) and Windows - XP, 2003 Server and 7. They all worked.

2011-09-20cifs: fix possible memory corruption in CIFSFindNextJeff Layton1-1/+2
The name_len variable in CIFSFindNext is a signed int that gets set to the resume_name_len in the cifs_search_info. The resume_name_len however is unsigned and for some infolevels is populated directly from a 32 bit value sent by the server. If the server sends a very large value for this, then that value could look negative when converted to a signed int. That would make that value pass the PATH_MAX check later in CIFSFindNext. The name_len would then be used as a length value for a memcpy. It would then be treated as unsigned again, and the memcpy scribbles over a ton of memory. Fix this by making the name_len an unsigned value in CIFSFindNext.

2011-08-16cifs: demote cERROR in build_path_from_dentry to cFYIJeff Layton1-2/+2
Running the cthon tests on a recent kernel caused this message to pop occasionally: CIFS VFS: did not end path lookup where expected namelen is 0 Some added debugging showed that namelen and dfsplen were both 0 when this occurred. That means that the read_seqretry returned true. Assuming that the comment inside the if statement is true, this should be harmless and just means that we raced with a rename. If that is the case, then there's no need for alarm and we can demote this to cFYI. While we're at it, print the dfsplen too so that we can see what happened here if the message pops during debugging.

2011-08-11cifs: Do not set cifs/ntfs acl using a file handle (try #4)Shirish Pargaonkar1-27/+1
Set security descriptor using path name instead of a file handle. We can't be sure that the file handle has adequate permission to set a security descriptor (to modify DACL). Function set_cifs_acl_by_fid() has been removed since we can't be sure how a file was opened for writing, a valid request can fail if the file was not opened with two above mentioned permissions. We could have opted to add on WRITE_DAC and WRITE_OWNER permissions to file opens and then use that file handle but adding addtional permissions such as WRITE_DAC and WRITE_OWNER could cause an any open to fail. And it was incorrect to look for read file handle to set a security descriptor anyway. Signed-off-by: Shirish Pargaonkar <shirishpargaonkar@gmail.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

Currently, we take a sb->s_active reference and a cifsFileInfo reference when an oplock break workqueue job is queued. This is unnecessary and more complicated than it needs to be. Also as Al points out, deactivate_super has non-trivial locking implications so it's best to avoid that if we can. Instead, just cancel any pending oplock breaks for this filehandle synchronously in cifsFileInfo_put after taking it off the lists. That should ensure that this job doesn't outlive the structures it depends on.

The comparison will succeed since we're only looking at the first 3 characters. Fix this by also comparing the length of the provided ea_name with the name_len in the response.
