* fatfs: add FAT_IOCTL_GET_VOLUME_IDMike Lockwood2013-07-093-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch, originally from Android kernel, adds vfat ioctl command FAT_IOCTL_GET_VOLUME_ID, with this command we can get the vfat volume ID using following code: ioctl(fd, FAT_IOCTL_GET_VOLUME_ID, &volume_ID) This patch is a modified version of the patch by Mike Lockwood, with changes from Dmitry Pervushin, who noticed the original patch makes some volume IDs abiguous with error returns: for example, if volume id is 0xFFFFFDAD, that matches -ENOIOCTLCMD, we get "FFFFFFFF" from the user space. So add a parameter to ioctl to get the correct volume ID. Android uses vfat volume ID to identify different sd card, when a new sd card is inserted to device, android can scan the media on it and pop up new contents.

* mm/writeback: don't check force_wait to handle bdi->work_listWanpeng Li2013-07-091-8/+2
| | | | | | | | | | | | | | | | After commit 839a8e8660b6 ("writeback: replace custom worker pool implementation with unbound workqueue"), bdi_writeback_workfn runs off bdi_writeback->dwork, on each execution, it processes bdi->work_list and reschedules if there are more things to do instead of flush any work that race with us existing. It is unecessary to check force_wait in wb_do_writeback since it is always 0 after the mentioned commit. This patch remove the force_wait in wb_do_writeback.

* inotify: fix race when adding a new watchLino Sanfilippo2013-07-091-9/+4
| | | | | | | | | | | | | | | | | | | | In inotify_new_watch() the number of watches for a group is compared against the max number of allowed watches and increased afterwards. The check and incrementation is not done atomically, so it is possible for multiple concurrent threads to pass the check and increment the number of marks above the allowed max. This patch uses an inotify groups mark_lock to ensure that both check and incrementation are done atomic. Furthermore we dont have to worry about the race that allows a concurrent thread to add a watch just after inotify_update_existing_watch() returned with -ENOENT anymore, since this is also synchronized by the groups mark mutex now.

| | | | | | | | | | | | There is no need to use a special mutex to protect against the fcntl/close race (see dnotify.c for a description of this race).

* fanotify: fix races when adding/removing marksLino Sanfilippo2013-07-091-12/+37
| | | | | | | | | | | | | | | | | | | | | | | | | For both adding an event to an existing mark and destroying a mark we first have to find it via fsnotify_find_[inode|vfsmount]_mark(). But getting the mark and adding an event (or destroying it) is not done atomically. This opens a race where a thread is about to destroy a mark while another thread still finds the same mark and adds an event to its mask although it will be destroyed. Another race exists concerning the excess of a groups number of marks limit: When a mark is added the number of group marks is checked against the max number of marks per group and increased afterwards. Since check and increment is also not done atomically, this may result in 2 or more processes passing the check at the same time and increasing the number of group marks above the allowed limit. With this patch both races are avoided by doing the concerning operations with the groups mark mutex locked.

This facility allows what is basically "userspace interrupts" for performance monitor events. - A bunch of Transactional Memory vs. Signals bug fixes and HW breakpoint/watchpoint fixes by Michael Neuling.

It buys nothing and in fact it can grow more than necessary, expand doesn't check if it was already incremented by another task. Kill it, and introduce "static int core_name_size" updated by expand_corename(). This is obviously racy too but harmless, and core_name_size never grows for no reason. We do not bother to to calculate the "right" new size, we simply do kmalloc(size_we_need) and use ksize() to rely on kmalloc_index's decision. Finally change format_corename() to use expand_corename(), krealloc(NULL) is fine.

And it is buggy. If cn_printf() does expand_corename() cn_escape() writes to the freed memory. Introduce cn_esc_printf() which hopefully does this all right. It records the index before cn_vprintf(), not "char *" which is no longer valid (in general) after krealloc().

Length limits should be about the space available in the destination, not repurposed as a method to either always include or always exclude a trailing NULL byte. Either the NULL should always be copied (using strlcpy), or it should not be copied (using something like memcpy). Readable code should not depend on the weird behavior of strncpy when it hits the length limit. Better to avoid the anti-pattern entirely.

A consequence of this is that the pagevec_lru_add_file, pagevec_lru_add_anon and similar helpers are misleading as the caller no longer has direct control over what LRU the page is added to. Unused helpers are removed by this patch and existing users of pagevec_lru_add_file() are converted to use lru_cache_add_file() directly and use the per-cpu pagevecs instead of creating their own pagevec.
