Fix the syscall numbering of the mount API syscalls so that the numbers match between i386 and x86_64 and that they're in the common numbering scheme space. Fixes: a07b2000 ("vfs: syscall: Add open_tree(2) to reference or clone a mount") Fixes: 2db154b3 ("vfs: syscall: Add move_mount(2) to move mounts around") Fixes: 24dcb3d9 ("vfs: syscall: Add fsopen() to prepare for superblock creation") Fixes: ecdab150 ("vfs: syscall: Add fsconfig() for configuring and managing a context") Fixes: 93766fbd ("vfs: syscall: Add fsmount() to create a mount for a superblock") Fixes: cf3cba4a ("vfs: syscall: Add fspick() to select a superblock for reconfiguration") Reported-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NDavid Howells <dhowells@redhat.com> Reviewed-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

Make the name of the anon inode fd "[fscontext]" instead of "fscontext". This is minor but most core-kernel anon inode fds already carry square brackets around their name: [eventfd] [eventpoll] [fanotify] [io_uring] [pidfd] [signalfd] [timerfd] [userfaultfd] For the sake of consistency lets do the same for the fscontext anon inode fd that comes with the new mount api.

What triggers it is a race between mount --move and umount -l of the source; we should reject it (the source is parentless *and* not the root of anon namespace at that), but the check for namespace being an anon one is broken in that case - is_anon_ns() needs ns to be non-NULL. Better fixed here than in is_anon_ns(), since the rest of the callers is guaranteed to get a non-NULL argument...

Four modes are provided, settable by mount parameter: "flock=local" - No reference to the server "flock=openafs" - Fine-grained locks are local-only, whole-file locks require sufficient server locks "flock=strict" - All locks require sufficient server locks "flock=write" - Always get an exclusive server lock If the volume is a read-only or backup volume, then flock=local for that volume. - Log extra information for a couple of cases where the client mucks up somehow: AFS vnode with undefined type and dir check failure - in both cases we seem to end up with unfilled data, but the issues happen infrequently and are difficult to reproduce at will. - Implement silly rename for unlink() and rename(). - Set i_blocks so that du can get some information about usage. - Fix xattr handlers to return the right amount of data and to not overflow buffers. - Implement getting/setting raw AFS and YFS ACLs as xattrs" * tag 'afs-next-20190507' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: afs: Implement YFS ACL setting afs: Get YFS ACLs and information through xattrs afs: implement acl setting afs: Get an AFS3 ACL as an xattr afs: Fix getting the afs.fid xattr afs: Fix the afs.cell and afs.volume xattr handlers afs: Calculate i_blocks based on file size afs: Log more information for "kAFS: AFS vnode with undefined type\n" afs: Provide mount-time configurable byte-range file locking emulation afs: Add more tracepoints afs: Implement sillyrename for unlink and rename afs: Add directory reload tracepoint afs: Handle lock rpc ops failing on a file that got deleted afs: Improve dir check failure reports afs: Add file locking tracepoints afs: Further fix file locking afs: Fix AFS file locking to allow fine grained locks afs: Calculate lock extend timer from set/extend reply reception afs: Split wait from afs_make_call()

Pull staging / IIO driver updates from Greg KH: "Here is the big staging and iio driver update for 5.2-rc1. Lots of tiny fixes all over the staging and IIO driver trees here, along with some new IIO drivers. The "counter" subsystem was added in here as well, as it is needed by the IIO drivers and subsystem. Also we ended up deleting two drivers, making this pull request remove a few hundred thousand lines of code, always a nice thing to see. Both of the drivers removed have been replaced with "real" drivers in their various subsystem directories, and they will be coming to you from those locations during this merge window. There are some core vt/selection changes in here, that was due to some cleanups needed for the speakup fixes. Those have all been acked by the various subsystem maintainers (i.e. me), so those are ok. We also added a few new drivers, for some odd hardware, giving new developers plenty to work on with basic coding style cleanups to come in the near future. Other than that, nothing unusual here.

Silva: "Mark switch cases where we are expecting to fall through. This is part of the ongoing efforts to enable -Wimplicit-fallthrough.

We are getting close to completing this work. Currently, there are only 32 of 2311 of these cases left to be addressed in linux-next.

Pull pidfd updates from Christian Brauner: "This patchset makes it possible to retrieve pidfds at process creation time by introducing the new flag CLONE_PIDFD to the clone() system call. Linus originally suggested to implement this as a new flag to clone() instead of making it a separate system call. After a thorough review from Oleg CLONE_PIDFD returns pidfds in the parent_tidptr argument. This means we can give back the associated pid and the pidfd at the same time. Access to process metadata information thus becomes rather trivial. As has been agreed, CLONE_PIDFD creates file descriptors based on anonymous inodes similar to the new mount api. They are made unconditional by this patchset as they are now needed by core kernel code (vfs, pidfd) even more than they already were before (timerfd, signalfd, io_uring, epoll etc.). The core patchset is rather small. The bulky looking changelist is caused by David's very simple changes to Kconfig to make anon inodes unconditional. A pidfd comes with additional information in fdinfo if the kernel supports procfs. The fdinfo file contains the pid of the process in the callers pid namespace in the same format as the procfs status file, i.e. "Pid:\t%d". To remove worries about missing metadata access this patchset comes with a sample/test program that illustrates how a combination of CLONE_PIDFD and pidfd_send_signal() can be used to gain race-free access to process metadata through /proc/<pid>. Further work based on this patchset has been done by Joel. His work makes pidfds pollable. It finished too late for this merge window. I would prefer to have it sitting in linux-next for a while and send it for inclusion during the 5.3 merge window" * tag 'pidfd-v5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: samples: show race-free pidfd metadata access signal: support CLONE_PIDFD with pidfd_send_signal clone: add CLONE_PIDFD Make anon_inodes unconditional

Petr Štetiar says: ==================== of_get_mac_address ERR_PTR fixes this patch series is an attempt to fix the mess, I've somehow managed to introduce. First patch in this series is defacto v5 of the previous 05/10 patch in the series, but since the v4 of this 05/10 patch wasn't picked up by the patchwork for some unknown reason, this patch wasn't applied with the other 9 patches in the series, so I'm resending it as a separate patch of this fixup series again. Second patch is a result of this rebase against net-next tree, where I was checking again all current users of of_get_mac_address and found out, that there's new one in DSA, so I've converted this user to the new ERR_PTR encoded error value as well. Third patch which was sent as v5 wasn't considered for merge, but I still think, that we need to check for possible NULL value, thus current IS_ERR check isn't sufficient and we need to use IS_ERR_OR_NULL instead.
