| * [PATCH] splice: fixup writeout path after ->map changesJens Axboe2006-04-191-19/+30
| | | | | | | | | | | | | | | | Since ->map() no longer locks the page, we need to adjust the handling of those pages (and stealing) a little. This now passes full regressions again. Signed-off-by: Jens Axboe <axboe@suse.de>
| * [PATCH] splice: offset fixesJens Axboe2006-04-191-15/+30
| | | | | | | | | | | | | | | | - We need to adjust *ppos for writes as well. - Copy back modified offset value if one was passed in, similar to what sendfile does. Signed-off-by: Jens Axboe <axboe@suse.de>
| * [PATCH] tee: link_pipe() must be careful when dropping one of the pipe locksJens Axboe2006-04-191-4/+14
| | | | | | | | | | | | | | We need to ensure that we only drop a lock that is ordered last, to avoid ABBA deadlocks with competing processes. Signed-off-by: Jens Axboe <axboe@suse.de>
| * [PATCH] splice: cleanup the SPLICE_F_NONBLOCK handlingJens Axboe2006-04-191-14/+16
| | | | | | | | | | | | | | | | - generic_file_splice_read() more readable and correct - Don't bail on page allocation with NONBLOCK set, just don't allow direct blocking on IO (eg lock_page). Signed-off-by: Jens Axboe <axboe@suse.de>

* | [PATCH] Fix file lookup without refDipankar Sarma2006-04-192-8/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are places in the kernel where we look up files in fd tables and access the file structure without holding refereces to the file. So, we need special care to avoid the race between looking up files in the fd table and tearing down of the file in another CPU. Otherwise, one might see a NULL f_dentry or such torn down version of the file. This patch fixes those special places where such a race may happen.

* | [PATCH] task: Make task list manipulations RCU safeEric W. Biederman2006-04-191-1/+1
|/ | | | | | | | | | | | | | | | | While we can currently walk through thread groups, process groups, and sessions with just the rcu_read_lock, this opens the door to walking the entire task list. We already have all of the other RCU guarantees so there is no cost in doing this, this should be enough so that proc can stop taking the tasklist lock during readdir. prev_task was killed because it has no users, and using it will miss new tasks when doing an rcu traversal.

* x86: be careful about tailcall breakage for sys_open[at] tooLinus Torvalds2006-04-181-2/+14
| | | | | | | | | | | | | | Came up through a quick grep for other cases similar to the ftruncate() one in commit 0a489cb3b6a7b277030cdbc97c2c65905db94536. Also, add a comment, so that people who read the code understand why we do what looks like a no-op. (Again, this won't actually matter to any sane user, since libc will save and restore the register gcc stomps on, but it's still wrong to stomp on it) Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* x86: don't allow tail-calls in sys_ftruncate[64]()Linus Torvalds2006-04-181-2/+6
| | | | | | | | | | | | | | | | | | | | Gcc thinks it owns the incoming argument stack, but that's not true for "asmlinkage" functions, and it corrupts the caller-set-up argument stack when it pushes the third argument onto the stack. Which can result in %ebx getting corrupted in user space. Now, normally nobody sane would ever notice, since libc will save and restore %ebx anyway over the system call, but it's still wrong. I'd much rather have "asmlinkage" tell gcc directly that it doesn't own the stack, but no such attribute exists, so we're stuck with our hacky manual "prevent_tail_call()" macro once more (we've had the same issue before with sys_waitpid() and sys_wait4()). Thanks to Hans-Werner Hilse <hilse@sub.uni-goettingen.de> for reporting the issue and testing the fix. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] BLOCK: delay all uevents until partition table is scannedKay Sievers2006-04-141-8/+30
| | | | | | | | | | | | | | | | | | | | [BLOCK] delay all uevents until partition table is scanned Here we delay the annoucement of all block device events until the disk's partition table is scanned and all partition devices are already created and sysfs is populated. We have a bunch of old bugs for removable storage handling where we probe successfully for a filesystem on the raw disk, but at the same time the kernel recognizes a partition table and creates partition devices. Currently there is no sane way to tell if partitions will show up or not at the time the disk device is announced to userspace. With the delayed events we can simply skip any probe for a filesystem on the raw disk when we find already present partitions.

* [PATCH] sysfs: Allow sysfs attribute files to be pollableNeilBrown2006-04-143-0/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | It works like this: Open the file Read all the contents. Call poll requesting POLLERR or POLLPRI (so select/exceptfds works) When poll returns, close the file and go to top of loop. or lseek to start of file and go back to the 'read'. Events are signaled by an object manager calling sysfs_notify(kobj, dir, attr); If the dir is non-NULL, it is used to find a subdirectory which contains the attribute (presumably created by sysfs_create_group). This has a cost of one int per attribute, one wait_queuehead per kobject, one int per open file. The name "sysfs_notify" may be confused with the inotify functionality. Maybe it would be nice to support inotify for sysfs attributes as well? This patch also uses sysfs_notify to allow /sys/block/md*/md/sync_action to be pollable Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * [fuse] fix deadlock between fuse_put_super() and request_end()Miklos Szeredi2006-04-113-31/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A deadlock was possible, when the last reference to the superblock was held due to a background request containing a file reference. Releasing the file would release the vfsmount which in turn would release the superblock. Since sbput_sem is held during the fput() and fuse_put_super() tries to acquire this same semaphore, a deadlock results. The chosen soltuion is to get rid of sbput_sem, and instead use the spinlock to ensure the referenced inodes/file are released only once. Since the actual release may sleep, defer these outside the locked region, but using local variables instead of the structure members. This is a much more rubust solution.

| * | [PATCH] splice: add support for sys_tee()Jens Axboe2006-04-112-0/+193
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basically an in-kernel implementation of tee, which uses splice and the pipe buffers as an intelligent way to pass data around by reference. Where the user space tee consumes the input and produces a stdout and file output, this syscall merely duplicates the data inside a pipe to another pipe. No data is copied, the output just grabs a reference to the input pipe data. Signed-off-by: Jens Axboe <axboe@suse.de>

* | [PATCH] de_thread: Don't change our parents and ptrace flags.Eric W. Biederman2006-04-141-27/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is two distinct changes. - Not changing our real parents. - Not changing our ptrace parents. Not changing our real parents is trivially correct because both tasks have the same real parents as they are part of a thread group. Now that we demote the leader to a thread there is no longer any reason to change it's parentage. Not changing our ptrace parents is a user visible change if someone looks hard enough. I don't think user space applications will care or even notice. In the practical and I think common case a debugger will have attached to all of the threads using the same ptrace flags. From my quick skim of strace and gdb that appears to be the case. Which if true means debuggers will not notice a change. Before this point we have already generated a ptrace event in do_exit that reports the leaders pid has died so de_thread is visible to a debugger. Which means attempting to hide this case by copying flags around appears excessive. By not doing anything it avoids all of the weird locking issues between de_thread and ptrace attach, and removes one case from consideration for fixing the ptrace locking. This only addresses Oleg's first concern with ptrace_attach, that of the problems caused by reparenting. Oleg's second concern is essentially a race between ptrace_attach and release_task that causes an oops when we get to force_sig_specific. There is nothing special about de_thread with respect to that race. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Providing a NULL offset pointer means the existing f_pos will be used (and updated in situ). Providing an offset for a pipe results in -ESPIPE. Providing an invalid offset pointer results in -EFAULT.
