This is due to the lack of\nlocking between threads while sending out the messages.\n\nWhen a connected TCP send(), sendto(), or sendmsg() arrives in the Linux\nkernel, it eventually comes through tcp_sendmsg(). tcp_sendmsg() protects\nitself by acquiring a lock at invocation by calling lock_sock().\ntcp_sendmsg() then loops over the buffers in the iovec, allocating\nassociated sk_buff\u0027s and cache pages for use in the actual send. As it does\nso, it pushes the data out to tcp for actual transmission. However, if one\nof those allocation fails (because a large number of large sends is being\nprocessed, for example), it must wait for memory to become available. It\ndoes so by jumping to wait_for_sndbuf or wait_for_memory, both of which\neventually cause a call to sk_stream_wait_memory(). sk_stream_wait_memory()\ncontains a code path that calls sk_wait_event(). Finally, sk_wait_event()\ncontains the call to release_sock().\n\nThe following patch adds a lock to the socket container in order to\nproperly serialize outbound requests.\n\nFrom: Zhen Wei \u003czwei@novell.com\u003e\nAcked-by: Jeff Mahoney \u003cjeffm@suse.com\u003e\nSigned-off-by: Mark Fasheh \u003cmark.fasheh@oracle.com\u003e\n" }, { "commit": "f71aa8a55a0ae1a0d06c6079265d16502a678e8e", "tree": "adb5b97c984fd96eada350a7b90986b711f50348", "parents": [ "0dd82141b236ce36253e3056c6068ee3d5732196" ], "author": { "name": "Randy Dunlap", "email": "randy.dunlap@oracle.com", "time": "Thu Jan 25 14:51:50 2007 -0800" }, "committer": { "name": "Mark Fasheh", "email": "mark.fasheh@oracle.com", "time": "Wed Feb 07 12:14:27 2007 -0800" }, "message": "[PATCH] ocfs2: drop INET from Kconfig, not needed\n\nOCFS2: drop \u0027depends on INET\u0027 since local mounts are now allowed.\n\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Mark Fasheh \u003cmark.fasheh@oracle.com\u003e\n" }, { "commit": "0dd82141b236ce36253e3056c6068ee3d5732196", "tree": "51c4c4746ffa390d4dba6a342aeaa526a35cb4eb", "parents": [ "e4968476a9bc5a6b30076076b4f3ce3e692e0d79" ], "author": { "name": "Sunil Mushran", "email": "sunil.mushran@oracle.com", "time": "Mon Jan 29 15:44:27 2007 -0800" }, "committer": { "name": "Mark Fasheh", "email": "mark.fasheh@oracle.com", "time": "Wed Feb 07 12:10:39 2007 -0800" }, "message": "ocfs2_dlm: Add timeout to dlm join domain\n\nCurrently the ocfs2 dlm has no timeout during dlm join domain.

Now it turns out that there was a special case of glocks being\nused for prefetching the metadata, but because of the timeouts for these\nlocks (set to 10 secs) the metadata was being timed out before it was\nbeing used and this the prefetch code was constantly trying to prefetch\nthe same data over and over.\n\nCalling \"ls -l\" meant that the inodes were brought into memory and once\nthe inodes are cached, the glocks are not disposed of until the inodes\nare pushed out of the cache, thus extending the lifetime of the glocks,\nand thus bringing down the time for subsequent runs of \"ls\"\nconsiderably.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "a8d638e30e768adc6956541f79f7bf05139ba475", "tree": "07cee3c3d06eee9ff138f17023c7dadcb338f467", "parents": [ "222d396092acc11b4af03bede309aa066945e920" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Jan 15 13:52:17 2007 +0000" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Feb 05 13:37:01 2007 -0500" }, "message": "[GFS2] Add writepages for \"data\u003dwriteback\" mounts\n\nIt occurred to me that although a gfs2 specific writepages for ordered\nwrites and journaled data would be tricky, by hooking writepages only\nfor \"data\u003dwriteback\" mounts we could take advantage of not needing\nbuffer heads (we don\u0027t use them on the read side, nor have we for some\ntime) and create much larger I/Os for the block layer.\n\nUsing blktrace both before and after, its possible to see that for large\nI/Os, most of the requests generated through writepages are now 1024\nsectors after this patch is applied as opposed to 8 sectors before.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "222d396092acc11b4af03bede309aa066945e920", "tree": "ec8e0ac0183faad1167af24ff33ba23ba0db85b1", "parents": [ "a1bc86e6bddd34362ca08a3a4d898eb4b5c15215" ], "author": { "name": "David Teigland", "email": "teigland@redhat.com", "time": "Mon Jan 15 10:28:22 2007 -0600" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Feb 05 13:36:58 2007 -0500" }, "message": "[DLM] fix master recovery\n\nIf master recovery happens on an rsb in one recovery sequence, then that\nsequence is aborted before lock recovery happens, then in the next\nsequence, we rely on the previous master recovery (which may now be\ninvalid due to another node ignoring a lookup result) and go on do to the\nlock recovery where we get stuck due to an invalid master value.\n\n recovery cycle begins: master of rsb X has left\n nodes A and B send node C an rcom lookup for X to find the new master\n C gets lookup from B first, sets B as new master, and sends reply back to B\n C gets lookup from A next, and sends reply back to A saying B is master\n A gets lookup reply from C and sets B as the new master in the rsb\n recovery cycle on A, B and C is aborted to start a new recovery\n B gets lookup reply from C and ignores it since there\u0027s a new recovery\n recovery cycle begins: some other node has joined\n B doesn\u0027t think it\u0027s the master of X so it doesn\u0027t rebuild it in the directory\n C looks up the master of X, no one is master, so it becomes new master\n B looks up the master of X, finds it\u0027s C\n A believes that B is the master of X, so it sends its lock to B\n B sends an error back to A\n A resends\n this repeats forever, the incorrect master value on A is never corrected\n\nThe fix is to do master recovery on an rsb that still has the NEW_MASTER\nflag set from an earlier recovery sequence, and therefore didn\u0027t complete\nlock recovery.\n\nSigned-off-by: David Teigland \u003cteigland@redhat.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "a1bc86e6bddd34362ca08a3a4d898eb4b5c15215", "tree": "92b30f8f9400c5a1b71a2e3a17397b9d0b2cc2f2", "parents": [ "1d6e8131cf0064ef5ab5f3411a82b800afbfadee" ], "author": { "name": "David Teigland", "email": "teigland@redhat.com", "time": "Mon Jan 15 10:34:52 2007 -0600" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Feb 05 13:36:55 2007 -0500" }, "message": "[DLM] fix user unlocking\n\nWhen a user process exits, we clear all the locks it holds.

Likewise the return value test of !\u003d\n1 might look a bit odd and thats because we\u0027ll need a third return value\nin case of requiring an allocation.\n\nI\u0027ve made the change to deferred mode on the glock to ensure flushing\nread caches on other nodes. I notice that (using blktrace to look at\nwhats going on) we appear to do a better job of large I/Os than ext3\nafter this patch (in terms of not splitting up the I/Os).\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\nCc: Wendy Cheng \u003cwcheng@redhat.com\u003e\n" }, { "commit": "927255f0383342f5d49b82adb6689b9cba52a6f5", "tree": "128aa611a70e73664d38344ae4da0251635c1699", "parents": [ "075529b5e1ffa8c9864d23930b71b5306a13d9f8" ], "author": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Tue Dec 19 13:04:03 2006 -0800" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Feb 05 13:36:05 2007 -0500" }, "message": "[DLM] fs/dlm/lowcomms-tcp.c: remove 2 functions\n\nRemove the following unused functions:\n\n- lowcomms_send_message()\n- lowcomms_max_buffer_size()\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Patrick Caulfield \u003cpcaulfie@redhat.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "075529b5e1ffa8c9864d23930b71b5306a13d9f8", "tree": "414833bf6041a82f9e0cd2f813b05fe2da37ead8", "parents": [ "8d07fd509e9c82a59e37b8b18a2fd0e8ef8fc837" ], "author": { "name": "David Teigland", "email": "teigland@redhat.com", "time": "Wed Dec 13 10:40:26 2006 -0600" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Feb 05 13:36:02 2007 -0500" }, "message": "[DLM] fix lost flags in stub replies\n\nWhen the dlm fakes an unlock/cancel reply from a failed node using a stub\nmessage struct, it wasn\u0027t setting the flags in the stub message.
