* [CIFS] file create with acl support enabled is slowSteve French2008-03-14
| | | | | | | | | | | | | | | | 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.

| | | | | | | | Christoph had noticed too many ifdefs in the CIFS code making it hard to read. This patch removes about a quarter of them from the C files in cifs by improving a few key ifdefs in the .h files. Signed-off-by: Steve French <sfrench@us.ibm.com>

* [CIFS] Fix buffer overflow if server sends corrupt response to smallSteve French2007-11-13
| | | | | | | | | | | | | | | | | | | request In SendReceive() function in transport.c - it memcpy's message payload into a buffer passed via out_buf param. The function assumes that all buffers are of size (CIFSMaxBufSize + MAX_CIFS_HDR_SIZE) , unfortunately it is also called with smaller (MAX_CIFS_SMALL_BUFFER_SIZE) buffers. There are eight callers (SMB worker functions) which are primarily affected by this change: TreeDisconnect, uLogoff, Close, findClose, SetFileSize, SetFileTimes, Lock and PosixLock CC: Dave Kleikamp <shaggy@austin.ibm.com> CC: Przemyslaw Wegrzyn <czajnik@czajsoft.pl> Acked-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
* [CIFS] implement upcalls for SPNEGO blob via keyctl APIJeff Layton2007-11-03
| | | | | | | | | | | | | | | Add routines to handle upcalls to userspace via keyctl for the purpose of getting a SPNEGO blob for a particular uid and server combination. Clean up the Makefile a bit and set it up to only compile cifs_spnego if CONFIG_CIFS_UPCALL is set. Also change CONFIG_CIFS_UPCALL to depend on CONFIG_KEYS rather than CONFIG_CONNECTOR. cifs_spnego.h defines the communications between kernel and userspace and is intended to be shared with userspace programs.

| | | | | | | | | | In the cleanup phase of the dbench test, we were noticing sharing violation followed by failed directory removals when dbench did not close the test files before the cleanup phase started.

* [CIFS] NTLMv2 support part 5Steve French2006-06-08
| | | | | | | | | | | | | | | NTLMv2 authentication (stronger authentication than default NTLM) which many servers support now works. There was a problem with the construction of the security blob in the older code. Currently requires /proc/fs/cifs/Experimental to be set to 2 and /proc/fs/cifs/SecurityFlags to be set to 0x4004 (to require using NTLMv2 instead of default of NTLM) Next we will check signing to make sure optional NTLMv2 packet signing also works.

* [CIFS] SessionSetup cleanup part 2Steve French2006-02-13
| | | | | | | | | | | | | The cifs session setup code has three cases, and a fourth for backlevel LANMAN2 style session setup needed to be added. This new session setup implmentation will eventually replace the other three and should be easier to read while fixing a few minor problems (not setting the LARGE READ/WRITEX flags when NTLMSSP was negotiated for example) and adding support for NTLMv2 (which will be added with the next patch. In the meantime, this code is marked in an CONFIG_CIFS_EXPERIMENTAL block and will not be turned on by default until it is tested against more server types.
