CIFS in some heavy stress conditions cifs could get EAGAIN repeatedly in smb_send2 which led to repeated retries and eventually failure of large writes which could lead to data corruption. There are three changes that were suggested by various network developers: 1) convert cifs from non-blocking to blocking tcp sendmsg (we left in the retry on failure) 2) change cifs to not set sendbuf and rcvbuf size for the socket (let tcp autotune the buffer sizes since that works much better in the TCP stack now) 3) if we have a partial frame sent in smb_send2, mark the tcp session as invalid (close the socket and reconnect) so we do not corrupt the remaining part of the SMB with the beginning of the next SMB. This does not appear to hurt performance measurably and has been run in various scenarios, but it definately removes a corruption that we were seeing in some high stress test cases.

fcntl(F_SETLEASE) currently is not exported by cifs (nor by local file systems) so cifs grants leases based on how other local processes have opened the file not by whether the file is cacheable (oplocked). This adds the check to make sure that the file is cacheable on the client before checking whether we can grant the lease locally (generic_setlease). It also adds a mount option for cifs (locallease) if the user wants to override this and try to grant leases even if the server did not grant oplock. Signed-off-by: NSteve French <sfrench@us.ibm.com>

When we do a seekdir() or equivalent, we usually end up doing a FindFirst call and then call FindNext until we get to the offset that we want. The problem is that when we call FindNext, the code usually doesn't have the proper info (mostly, the filename of the entry from the last search) to resume the search. Add a "last_entry" field to the cifs_search_info that points to the last entry in the search. We calculate this pointer by using the LastNameOffset field from the search parms that are returned. We then use that info to do a cifs_save_resume_key before we call CIFSFindNext. This patch allows CIFS to reliably pass the "telldir" connectathon test.

Properly handle MSKRB5 by passing sec=mskrb5 to the upcall so that the spengo blob can be generated appropriately. Also, make decode_negTokenInit prefer whichever mechanism is first in the list. Needed for some NetApp servers, and possibly some older versions of Windows which treat the two KRB5 mechanisms differently.

Have CIFS_SessSetup call cifs_get_spnego_key when Kerberos is negotiated. Use the info in the key payload to build a session setup request packet. Also clean up how the request buffer in the function is freed on error. With appropriate user space helper (in samba/source/client). Kerberos support (secure session establishment can be done now via Kerberos, previously users would have to use NTLMv2 instead for more secure session setup).

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.

Fixes two problems: 1) we dropped down to negotiating lanman if we did not recognize the mechanism (krb5 e.g.) 2) we did not stop cifsd (thus will fail when doing rmod cifs with slab free errors) when we fail tcon but have a bad session (which is the case in which signing is required but we don't allow signing on the client) It also turns on extended security flag in the header when passing "sec=krb5" on mount command (although kerberos support is not done of course) Acked-by: NJeff Layton <jlayton@redhat.com> CC: Shaggy <shaggy@us.ibm.com> Signed-off-by: NSteve French <sfrench@us.ibm.com>

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).

Fix dialect negotiation to save off when we have negotiated lanman. This allows us to avoid sending some somewhat newer requests that the server can not handle and go directly to the older version (infolevel) of the same call. Make sure we try to negotiate a level which allows us to get the server OS (which we check so we can detect Win9x vs. other legacy servers and eventually work around the Win9x DOS time bug (they reverse date/time fields).

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.
