2006-03-25[PATCH] x86_64: Increase the variability of the process stack on 64bit ↵Andi Kleen
architectures 8MB is not really very random, use 1GB (or more with larger page sizes) instead. Also use the low bits of the random generator output now instead of throwing them away. Only enabled on x86-64 right now. Other architectures need to add a suitable STACK_RND_MASK Cc: mingo@elte.hu Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-03-25[PATCH] direct-io: bug fix in dio handling write errorChen, Kenneth W
There is a bug in direct-io on propagating write error up to the higher I/O layer. When performing an async ODIRECT write to a block device, if a device error occurred (like media error or disk is pulled), the error code is only propagated from device driver to the DIO layer. The error code stops at finished_one_bio(). The aysnc write, however, is supposedly have a corresponding AIO event with appropriate return code (in this case -EIO). Application which waits on the async write event, will hang forever since such AIO event is lost forever (if such app did not use the timeout option in io_getevents call. Regardless, an AIO event is lost). The discovery of above bug leads to another discovery of potential race window with dio->result. The fundamental problem is that dio->result is overloaded with dual use: an indicator of fall back path for partial dio write, and an error indicator used in the I/O completion path. In the event of device error, the setting of -EIO to dio->result clashes with value used to track partial write that activates the fall back path. It was also pointed out that it is impossible to use dio->result to track partial write and at the same time to track error returned from device driver. Because direct_io_work can only determines whether it is a partial write at the end of io submission and in mid stream of those io submission, a return code could be coming back from the driver. Thus messing up all the subsequent logic. Proposed fix is to separating out error code returned by the IO completion path from partial IO submit tracking. A new variable is added to dio structure specifically to track io error returned in the completion path.

2006-03-25[PATCH] udf: fix uid/gid options and add uid/gid=ignore and forget optionsPhillip Susi
As Pekka Enberg pointed out, with the if still following the else, you can still get a null uid written to the disk if you specify a default uid= without uid=forget. In other words, if the desktop user is uid=1000 and the mount option uid=1000 is given ( which is done on ubuntu automatically and probably other distributions that use hal ), then if any other user besides uid 1000 owns a file then a 0 will be written to the media as the owning uid instead.

2006-03-25[PATCH] POLLRDHUP/EPOLLRDHUP handling for half-closed devices notificationsDavide Libenzi
Implement the half-closed devices notifiation, by adding a new POLLRDHUP (and its alias EPOLLRDHUP) bit to the existing poll/select sets. Since the existing POLLHUP handling, that does not report correctly half-closed devices, was feared to be changed, this implementation leaves the current POLLHUP reporting unchanged and simply add a new bit that is set in the few places where it makes sense. The same thing was discussed and conceptually agreed quite some time ago: http://lkml.org/lkml/2003/7/12/116 Since this new event bit is added to the existing Linux poll infrastruture, even the existing poll/select system calls will be able to use it. As far as the existing POLLHUP handling, the patch leaves it as is. The pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing archs and sets the bit in the six relevant files. The other attached diff is the simple change required to sys/epoll.h to add the EPOLLRDHUP definition. There is "a stupid program" to test POLLRDHUP delivery here: http://www.xmailserver.org/pollrdhup-test.c It tests poll(2), but since the delivery is same epoll(2) will work equally.

2006-03-25[PATCH] 9p: fix name consistency problemsEric Van Hensbergen
There were a number of conflicting naming schemes used in the v9fs project. The directory was fs/9p, but MAINTAINERS and Documentation referred to v9fs. The module name itself was 9p2000, and the file system type was 9P. This patch attempts to clean that up, changing all references to 9p in order to match the directory name. We'll also start using 9p instead of v9fs as our patch prefix. There is also a minor consistency cleanup in the options changing the name option to uname in order to more closely match the Plan 9 options.

2006-03-25[PATCH] inotify: lock avoidance with parent watch status in dentryNick Piggin
Previous inotify work avoidance is good when inotify is completely unused, but it breaks down if even a single watch is in place anywhere in the system. Robin Holt notices that udev is one such culprit - it slows down a 512-thread application on a 512 CPU system from 6 seconds to 22 minutes. Solve this by adding a flag in the dentry that tells inotify whether or not its parent inode has a watch on it. Event queueing to parent will skip taking locks if this flag is cleared. Setting and clearing of this flag on all child dentries versus event delivery: this is no in terms of race cases, and that was shown to be equivalent to always performing the check. The essential behaviour is that activity occuring _after_ a watch has been added and _before_ it has been removed, will generate events.

2006-03-25[PATCH] Missed error checking for intent's filp in open_namei().Oleg Drokin
It seems there is error check missing in open_namei for errors returned through intent.open.file (from lookup_instantiate_filp). If there is plain open performed, then such a check done inside __path_lookup_intent_open called from path_lookup_open(), but when the open is performed with O_CREAT flag set, then __path_lookup_intent_open is only called with LOOKUP_PARENT set where no file opening can occur yet. Later on lookup_hash is called where exact opening might take place and intent.open.file may be filled. If it is filled with error value of some sort, then we get kernel attempting to dereference this error value as address (and corresponding oops) in nameidata_to_filp() called from filp_open(). While this is relatively simple to workaround in ->lookup() method by just checking lookup_instantiate_filp() return value and returning error as needed, this is not so easy in ->d_revalidate(), where we can only return "yes, dentry is valid" or "no, dentry is invalid, perform full lookup again", and just returning 0 on error would cause extra lookup (with potential extra costly RPCs). So in short, I believe that there should be no difference in error handling for opening a file and creating a file in open_namei() and propose this simple patch as a solution.

2006-03-25[PATCH] Optimise d_find_alias()David Howells
The attached patch optimises d_find_alias() to only take the spinlock if there's anything in the the inode's alias list. If there isn't, it returns NULL immediately. With respect to the superblock sharing patch, this should reduce by one the number of times the dcache_lock is taken by nfs_lookup() for ordinary directory lookups. Only in the case where there's already a dentry for particular directory inode (such as might happen when another mountpoint is rooted at that dentry) will the lock then be taken the extra time.

2006-03-24[PATCH] ocfs2: dlm recovery fixesKurt Hackel
when starting lock mastery (excepting the recovery lock) wait on any nodes needing recovery. fix one instance where lock resources were left attached to the recovery list after recovery completed. ensure that the node_down code is run uniformly regardless of which node found the dead node first.
