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 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
2019-05-07net: macb: Change interrupt and napi enable order in openHarini Katakam1-3/+3
Current order in open: -> Enable interrupts (macb_init_hw) -> Enable NAPI -> Start PHY Sequence of RX handling: -> RX interrupt occurs -> Interrupt is cleared and interrupt bits disabled in handler -> NAPI is scheduled -> In NAPI, RX budget is processed and RX interrupts are re-enabled With the above, on QEMU or fixed link setups (where PHY state doesn't matter), there's a chance macb RX interrupt occurs before NAPI is enabled. This will result in NAPI being scheduled before it is enabled. Fix this macb open by changing the order.

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.

I'm hesitant to just change IS_ERR into IS_ERR_OR_NULL check, as this would make the warning disappear also, but it would be confusing to check for impossible return value just to make a compiler happy.

Commit 284eb160681c ("staging: octeon-ethernet: support of_get_mac_address new ERR_PTR error") has introduced checking for ERR_PTR encoded error value from of_get_mac_address with IS_ERR macro, which is not sufficient in this case, as the mac variable is set to NULL initialy and if the kernel is compiled without DT support this NULL would get passed to IS_ERR, which would lead to the wrong decision and would pass that NULL pointer and invalid MAC address further.

2019-05-07taprio: add null check on sched_nest to avoid potential null pointer dereferenceColin Ian King1-0/+2
The call to nla_nest_start_noflag can return a null pointer and currently this is not being checked and this can lead to a null pointer dereference when the null pointer sched_nest is passed to function nla_nest_end. Fix this by adding in a null pointer check.

Pull stream_open conversion from Kirill Smelkov: - remove unnecessary double nonseekable_open from drivers/char/dtlk.c as noticed by Pavel Machek while reviewing nonseekable_open -> stream_open mass conversion. - the mass conversion patch promised in commit 10dce8af3422 ("fs: stream_open - opener for stream-like files so that read and write can run simultaneously without deadlock") and is automatically generated by running $ make coccicheck MODE=patch COCCI=scripts/coccinelle/api/stream_open.cocci I've verified each generated change manually - that it is correct to convert - and each other nonseekable_open instance left - that it is either not correct to convert there, or that it is not converted due to current stream_open.cocci limitations. More details on this in the patch. - finally, change VFS to pass ppos=NULL into .read/.write for files that declare themselves streams. It was suggested by Rasmus Villemoes and makes sure that if ppos starts to be erroneously used in a stream file, such bug won't go unnoticed and will produce an oops instead of creating illusion of position change being taken into account. Note: this patch does not conflict with "fuse: Add FOPEN_STREAM to use stream_open()" that will be hopefully coming via FUSE tree, because fs/fuse/ uses new-style .read_iter/.write_iter, and for these accessors position is still passed as non-pointer kiocb.ki_pos . * tag 'stream_open-5.2' of https://lab.nexedi.com/kirr/linux: vfs: pass ppos=NULL to .read()/.write() of FMODE_STREAM files *: convert stream-like files from nonseekable_open -> stream_open dtlk: remove double call to nonseekable_open
