2008-03-14[CIFS] file create with acl support enabled is slowSteve French1-2/+3
Shirish Pargaonkar noted: With cifsacl mount option, when a file is created on the Windows server, exclusive oplock is broken right away because the get cifs acl code again opens the file to obtain security descriptor. The client does not have the newly created file handle or inode in any of its lists yet so it does not respond to oplock break and server waits for its duration and then responds to the second open. This slows down file creation signficantly. The fix is to pass the file descriptor to the get cifsacl code wherever available so that get cifs acl code does not send second open (NT Create ANDX) and oplock is not broken.

Andi Kleen noticed that we were logging access denied errors (which is noisy in the dmesg log, and not needed to be logged) and that we were logging path names on that an other errors (e.g. EIO) which we should not be doing.

2007-09-28[CIFS] CIFS support for named pipes (part 1)Steve French1-1/+1
This allows cifs to mount to ipc shares (IPC$) which will allow user space applications to layer over authenticated cifs connections (useful for Wine and others that would want to put DCE/RPC over CIFS or run CIFS named pipes) Acked-by: Rob Shearman <rob@codeweavers.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2007-07-18[CIFS] Allow disabling CIFS Unix Extensions as mount optionSteve French1-6/+5
Previously the only way to do this was to umount all mounts to that server, turn off a proc setting (/proc/fs/cifs/LinuxExtensionsEnabled). Fixes Samba bugzilla bug number: 4582 (and also 2008) Signed-off-by: Steve French <sfrench@us.ibm.com>
2007-07-11[CIFS] Fix oops in cifs_create when nfsd server exports cifs mountSteve French1-1/+2
nfsd is passing null nameidata (probably the only one doing that) on call to create - cifs was missing one check for this. Note that running nfsd over a cifs mount requires specifying fsid on the nfs exports entry and requires mounting cifs with serverino mount option. Signed-off-by: Steve French <sfrench@us.ibm.com>

2007-06-08[CIFS] CIFS should honour umaskSteve French1-2/+4
This patch makes CIFS honour a process' umask like other filesystems. Of course the server is still free to munge the permissions if it wants to; but the client will send the "right" permissions to begin with. A few caveats: 1) It only applies to filesystems that have CAP_UNIX (aka support unix extensions) 2) It applies the correct mode to the follow up CIFSSMBUnixSetPerms() after remote creation When mode to CIFS/NTFS ACL mapping is complete we can do the same thing for that case for servers which do not support the Unix Extensions.

2007-05-03[CIFS] Change semaphore to mutex for cifs lock_semRoland Dreier1-1/+1
Originally at http://lkml.org/lkml/2006/9/2/86 The recent change to "allow Windows blocking locks to be cancelled via a CANCEL_LOCK call" introduced a new semaphore in struct cifsFileInfo, lock_sem. However, semaphores used as mutexes are deprecated these days, and there's no reason to add a new one to the kernel. Therefore, convert lock_sem to a struct mutex (and also fix one indentation glitch on one of the lines changed anyway).

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+523
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
