2006-04-11[PATCH] fuse: account background requestsMiklos Szeredi3-4/+38
The previous patch removed limiting the number of outstanding requests. This patch adds a much simpler limiting, that is also compatible with file locking operations. A task may have at most one synchronous request allocated. So these requests need not be otherwise limited. However the number of background requests (release, forget, asynchronous reads, interrupted requests) can grow indefinitely. This can be used by a malicous user to cause FUSE to allocate arbitrary amounts of unswappable kernel memory, denying service. For this reason add a limit for the number of background requests, and block allocations of new requests until the number goes bellow the limit. Also use this mechanism to block all requests until the INIT reply is received.

2006-04-11[PATCH] fuse: clean up request accountingMiklos Szeredi5-208/+111
FUSE allocated most requests from a fixed size pool filled at mount time. However in some cases (release/forget) non-pool requests were used. File locking operations aren't well served by the request pool, since they may block indefinetly thus exhausting the pool. This patch removes the request pool and always allocates requests on demand.

2006-04-11[PATCH] fuse: simplify lockingMiklos Szeredi2-62/+33
This is in preparation for removing the global spinlock in favor of a per-mount one. The only critical part is the interaction between fuse_dev_release() and fuse_fill_super(): fuse_dev_release() must see the assignment to file->private_data, otherwise it will leak the reference to fuse_conn. This is ensured by the fput() operation, which will synchronize the assignment with other CPU's that may do a final fput() soon after this. Also redundant locking is removed from fuse_fill_super(), where exclusion is already ensured by the BKL held for this function by the VFS.

2006-04-11[PATCH] fuse: add O_ASYNC support to FUSE deviceJeff Dike3-1/+20
This adds asynchronous notification to FUSE - a FUSE server can request O_ASYNC on a /dev/fuse file descriptor and receive SIGIO when there is input available. One subtlety - fuse_dev_fasync, which is called when O_ASYNC is requested, does no locking, unlink the other methods. I think it's unnecessary, as the fuse_conn.fasync list is manipulated only by fasync_helper and kill_fasync, which provide their own locking. It would also be wrong to use the fuse_lock, as it's a spin lock and fasync_helper can sleep. My one concern with this is the fuse_conn going away underneath fuse_dev_fasync - sys_fcntl takes a reference on the file struct, so this seems not to be a problem.

2006-04-11[PATCH] fuse: fix fuse_dev_poll() return valueMiklos Szeredi1-5/+6
fuse_dev_poll() returned an error value instead of a poll mask. Luckily (or unluckily) -ENODEV does contain the POLLERR bit. There's also a race if filesystem is unmounted between fuse_get_conn() and spin_lock(), in which case this event will be missed by poll().

2006-04-11[PATCH] fuse: fix oops in fuse_send_readpages()Miklos Szeredi1-2/+6
During heavy parallel filesystem activity it was possible to Oops the kernel. The reason is that read_cache_pages() could skip pages which have already been inserted into the cache by another task. Occasionally this may result in zero pages actually being sent, while fuse_send_readpages() relies on at least one page being in the request. So check this corner case and just free the request instead of trying to send it. Reported and tested by Konstantin Isakov.

2006-04-11[PATCH] inotify: check for NULL inode in inotify_d_instantiateArnd Bergmann1-1/+1
The spufs file system creates files in a directory before instantiating the directory itself, which causes a NULL pointer access in inotify_d_instantiate since c32ccd87bfd1414b0aabfcd8dbc7539ad23bcbaa. I'd like to keep this behavior since it means that the user will not have access to files in the directory before I know that I succeed in creating everything in it. This patch adds a simple check for the inode to keep that working.

2006-04-11[PATCH] process accounting: take original leader's start_time in non-leader execRoland McGrath1-0/+12
The only record we have of the real-time age of a process, regardless of execs it's done, is start_time. When a non-leader thread exec, the original start_time of the process is lost. Things looking at the real-time age of the process are fooled, for example the process accounting record when the process finally dies. This change makes the oldest start_time stick around with the process after a non-leader exec. This way the association between PID and start_time is kept constant, which seems correct to me.

Fixed by simply rearranging the test later to work on sizeof(stack_fds) Currently SELECT_STACK_ALLOC is 256 so this doesn't happen, but it's nasty to have things like this hidden in the code.

2006-04-10[PATCH] de_thread: Don't confuse users do_each_thread.Eric W. Biederman1-1/+6
Oleg Nesterov spotted two interesting bugs with the current de_thread code. The simplest is a long standing double decrement of __get_cpu_var(process_counts) in __unhash_process. Caused by two processes exiting when only one was created. The other is that since we no longer detach from the thread_group list it is possible for do_each_thread when run under the tasklist_lock to see the same task_struct twice. Once on the task list as a thread_group_leader, and once on the thread list of another thread. The double appearance in do_each_thread can cause a double increment of mm_core_waiters in zap_threads resulting in problems later on in coredump_wait. To remedy those two problems this patch takes the simple approach of changing the old thread group leader into a child thread. The only routine in release_task that cares is __unhash_process, and it can be trivially seen that we handle cleaning up a thread group leader properly. Since de_thread doesn't change the pid of the exiting leader process and instead shares it with the new leader process. I change thread_group_leader to recognize group leadership based on the group_leader field and not based on pids. This should also be slightly cheaper then the existing thread_group_leader macro. I performed a quick audit and I couldn't see any user of thread_group_leader that cared about the difference. Signed-off-by: Eric W.

2006-04-02[PATCH] splice: page stealing needs to wait_on_page_writeback()Jens Axboe1-0/+9
Thanks to Andrew for the good explanation of why this is so. akpm writes: If a page is under writeback and we remove it from pagecache, it's still going to get written to disk. But the VFS no longer knows about that page, nor that this page is about to modify disk blocks. So there might be scenarios in which those blocks-which-are-about-to-be-written-to get reused for something else. When writeback completes, it'll scribble on those blocks. This won't happen in ext2/ext3-style filesystems in normal mode because the page has buffers and try_to_release_page() will fail. But ext2 in nobh mode doesn't attach buffers at all - it just sticks the page in a BIO, finds some new blocks, points the BIO at those blocks and lets it rip. While that write IO's in flight, someone could truncate the file. Truncate won't block on the writeout because the page isn't in pagecache any more. So truncate will the free the blocks from the file under the page's feet. Then something else can reallocate those blocks. Then write data to them. Now, the original write completes, corrupting the filesystem. Signed-off-by: Jens Axboe <axboe@suse.de>
