| | | | | | | | | | | | | | | | | | The sockaddr declared on the stack in cifs_get_tcp_session is too small for IPv6 addresses. Change it from "struct sockaddr" to "struct sockaddr_storage" to prevent stack corruption when IPv6 is used.

| * [CIFS] Make socket retry timeouts consistent between blocking and ↵Steve French2009-01-28
| | | | | | | | | | | | | | | | | | | | | | nonblocking cases We have used approximately 15 second timeouts on nonblocking sends in the past, and also 15 second SMB timeout (waiting for server responses, for most request types). Now that we can do blocking tcp sends, make blocking send timeout approximately the same (15 seconds). Signed-off-by: Steve French <sfrench@us.ibm.com>

| * cifs: turn smb_send into a wrapper around smb_sendvJeff Layton2009-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cifs: turn smb_send into a wrapper around smb_sendv Rename smb_send2 to smb_sendv to make it consistent with kernel naming conventions for functions that take a vector. There's no need to have 2 functions to handle sending SMB calls. Turn smb_send into a wrapper around smb_sendv. This also allows us to properly mark the socket as needing to be reconnected when there's a partial send from smb_send. Also, in practice we always use the address and noblocksnd flag that's attached to the TCP_Server_Info. There's no need to pass them in as separate args to smb_sendv.

* | epoll: drop max_user_instances and rely only on max_user_watchesDavide Libenzi2009-01-29
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | Linus suggested to put limits where the money is, and max_user_watches already does that w/out the need of max_user_instances. That has the advantage to mitigate the potential DoS while allowing pretty generous default behavior. Allowing top 4% of low memory (per user) to be allocated in epoll watches, we have: LOMEM MAX_WATCHES (per user) 512MB ~178000 1GB ~356000 2GB ~712000 A box with 512MB of lomem, will meet some challenge in hitting 180K watches, socket buffers math teaches us. No more max_user_instances limits then.

* nfsd: only set file_lock.fl_lmops in nfsd4_lockt if a stateowner is foundJeff Layton2009-01-27
| | | | | | | | | | | | | | | | | nfsd4_lockt does a search for a lockstateowner when building the lock struct to test. If one is found, it'll set fl_owner to it. Regardless of whether that happens, it'll also set fl_lmops. Given that this lock is basically a "lightweight" lock that's just used for checking conflicts, setting fl_lmops is probably not appropriate for it. This behavior exposed a bug in DLM's GETLK implementation where it wasn't clearing out the fields in the file_lock before filling in conflicting lock info. While we were able to fix this in DLM, it still seems pointless and dangerous to set the fl_lmops this way when we may have a NULL lockstateowner.

| * dlm: initialize file_lock struct in GETLK before copying conflicting lockJeff Layton2009-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dlm_posix_get fills out the relevant fields in the file_lock before returning when there is a lock conflict, but doesn't clean out any of the other fields in the file_lock. When nfsd does a NFSv4 lockt call, it sets the fl_lmops to nfsd_posix_mng_ops before calling the lower fs. When the lock comes back after testing a lock on GFS2, it still has that field set. This confuses nfsd into thinking that the file_lock is a nfsd4 lock. Fix this by making DLM reinitialize the file_lock before copying the fields from the conflicting lock.

| * dlm: fix plock notify callback to lockdDavid Teigland2009-01-21
| | | | | | | | | | | | | | | | | | We should use the original copy of the file_lock, fl, instead of the copy, flc in the lockd notify callback. The range in flc has been modified by posix_lock_file(), so it will not match a copy of the lock in lockd. Signed-off-by: David Teigland <teigland@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Since ->acquire_dquot and ->release_dquot callbacks aren't called under dqptr_sem anymore, we don't have to start a transaction and obtain locks so early.

| * | quota: Improve lockingJan Kara2009-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We implement dqget() and dqput() that need neither dqonoff_mutex nor dqptr_sem. Then move dqget() and dqput() calls so that they are not called from under dqptr_sem. This is important because filesystem callbacks aren't called from under dqptr_sem which used to cause *lots* of problems with lock ranking (and with OCFS2 they became close to unsolvable). The patch also removes two functions which were introduced solely because OCFS2 needed them to cope with the old locking scheme. As time showed, they were not enough for OCFS2 anyway and it would be unnecessary work to adapt them to the new locking scheme in which they aren't needed. As a result OCFS2 needs the following patch to compile properly with quotas. Sorry to any bisecters which hit this in advance. Signed-off-by: Jan Kara <jack@suse.cz>
