Current code relies on the fact that invalid uid/gid as defined by UDF 2.60 3.3.3.1 and 3.3.3.2 coincides with invalid uid/gid as used by the user namespaces implementation. Since this is only lucky coincidence, clean this up to avoid future surprises in case user namespaces implementation changes. Also this is more robust in presence of valid (from UDF point of view) uids / gids which do not map into current user namespace.

Currently newly created files belong to current user despite uid=<number> / gid=<number> mount options. This is confusing to users (as owner of the file will change after remount / eviction from cache) and also inconsistent with e.g. FAT with the same mount option. So apply uid=<number> and gid=<number> also to newly created inodes and similarly as FAT disallow to change owner of the file in this case.

Currently uid=ignore and gid=ignore make no sense without uid=<number> and gid=<number> respectively as they result in all files having invalid uid / gid which then doesn't allow even root to modify files and thus causes confusion. And since commit ca76d2d8 "UDF: fix UID and GID mount option ignorance" (from over 10 years ago) uid=<number> overrides all uids on disk as uid=ignore does. So just silently ignore uid=ignore mount option. Reviewed-by: Pali Rohár <pali.rohar@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz>

Current handling of Partition Descriptors in Volume Descriptor Sequence is buggy in several ways. Firstly, it does not take descriptor sequence numbers into account at all, thus any volume making serious use of them would be unmountable. Secondly, it does not handle Volume Descriptor Pointers or Volume Descriptor Sequence without Terminating Descriptor. Fix these problems by properly remembering all Partition Descriptors in the Volume Descriptor Sequence and their sequence numbers. This is made more complicated by the fact that we don't know number of partitions in advance and sequence numbers have to be tracked on per-partition basis.

According to ECMA-167 3/8.4.2 a volume descriptor sequence can be terminated also by an unrecorded block within the extent of volume descriptor sequence. Currently we errored out in such case making such volumes unmountable. Handle that case by treating any invalid block as a block terminating the sequence.

According to ECMA-167 3/8.4.2 Volume Descriptor Pointer is terminating current extent of Volume Descriptor Sequence. Also according to ECMA-167 3/8.4.3 Volume Descriptor Sequence Number is not significant for Volume Descriptor Pointers. Simplify the handling of Volume Descriptor Pointers to take this into account.

We pass one block beyond end of volume descriptor sequence into process_sequence() as 'lastblock' instead of the last block of the sequence. When the sequence is not terminated with TD descriptor, this could lead to false errors due to invalid blocks in volume descriptor sequence and thus unmountable volumes.

Watch descriptor is id of the watch created by inotify_add_watch(). It is allocated in inotify_add_to_idr(), and takes the numbers starting from 1. Every new inotify watch obtains next available number (usually, old + 1), as served by idr_alloc_cyclic(). CRIU (Checkpoint/Restore In Userspace) project supports inotify files, and restores watched descriptors with the same numbers, they had before dump. Since there was no kernel support, we had to use cycle to add a watch with specific descriptor id: while (1) { int wd; wd = inotify_add_watch(inotify_fd, path, mask); if (wd < 0) { break; } else if (wd == desired_wd_id) { ret = 0; break; } inotify_rm_watch(inotify_fd, wd); } (You may find the actual code at the below link: https://github.com/checkpoint-restore/criu/blob/v3.7/criu/fsnotify.c#L577) The cycle is suboptiomal and very expensive, but since there is no better kernel support, it was the only way to restore that. Happily, we had met mostly descriptors with small id, and this approach had worked somehow. But recent time containers with inotify with big watch descriptors begun to come, and this way stopped to work at all. When descriptor id is something about 0x34d71d6, the restoring process spins in busy loop for a long time, and the restore hungs and delay of migration from node to node could easily be watched. This patch aims to solve this problem. It introduces new ioctl INOTIFY_IOC_SETNEXTWD, which allows to request the number of next created watch descriptor from userspace. It simply calls idr_set_cursor() primitive to populate idr::idr_next, so that next idr_alloc_cyclic() allocation will return this id, if it is not occupied. This is the way which is used to restore some other resources from userspace. For example, /proc/sys/kernel/ns_last_pid works the same for task pids. The new code is under CONFIG_CHECKPOINT_RESTORE #define, so small system may exclude it. v2: Use INT_MAX instead of custom definition of max id, as IDR subsystem guarantees id is between 0 and INT_MAX.

except, again, POLLFREE and POLL_BUSY_LOOP. With this, we finally get to the promised end result: - POLL{IN,OUT,...} are plain integers and *not* in __poll_t, so any stray instances of ->poll() still using those will be caught by sparse. - eventpoll.c and select.c warning-free wrt __poll_t - no more kernel-side definitions of POLL... - userland ones are visible through the entire kernel (and used pretty much only for mangle/demangle) - same behavior as after the first series (i.e. sparc et.al. epoll(2) working correctly).

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

After the preparations (in this series) switch to returning EPOLL... from ->poll() instances is completely mechanical and kernel-side POLL... can go away. The last step (killing kernel-side POLL... and unifying {de,}mangle_poll() has to be done after the search-and-replace job, since we need userland-side POLL... for unified {de,}mangle_poll(), thus the cherry-pick at the last step.
