afs: Fix incorrect error handling in afs_xattr_get_acl()
Fix incorrect error handling in afs_xattr_get_acl() where there appears to
be a redundant assignment before return, but in fact the return should be a
goto to the error handling at the end of the function.

afs: Fix key leak in afs_release() and afs_evict_inode()
Fix afs_release() to go through the cleanup part of the function if
FMODE_WRITE is set rather than exiting through vfs_fsync() (which skips the
cleanup). The cleanup involves discarding the refs on the key used for
file ops and the writeback key record.
Also fix afs_evict_inode() to clean up any left over wb keys attached to
the inode/vnode when it is removed.

Pull AFS updates from David Howells:
"A set of fix and development patches for AFS for 5.2.
Summary:
- Fix the AFS file locking so that sqlite can run on an AFS mount and
also so that firefox and gnome can use a homedir that's mounted
through AFS.
This required emulation of fine-grained locking when the server
will only support whole-file locks and no upgrade/downgrade. 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"

"We've got a reasonably broad set of audit patches for the v5.2 merge
window, the highlights are below:
- The biggest change, and the source of all the arch/* changes, is
the patchset from Dmitry to help enable some of the work he is
doing around PTRACE_GET_SYSCALL_INFO.
To be honest, including this in the audit tree is a bit of a
stretch, but it does help move audit a little further along towards
proper syscall auditing for all arches, and everyone else seemed to
agree that audit was a "good" spot for this to land (or maybe they
just didn't want to merge it? dunno.).
- We can now audit time/NTP adjustments.
- We continue the work to connect associated audit records into a
single event"

"We've got a few SELinux patches for the v5.2 merge window, the

- Add LSM hooks, and the SELinux implementation, for proper labeling

here, the rest of the LSM folks have given the hooks a thumbs-up.
- Update the SELinux mdp (Make Dummy Policy) script to actually work
on a modern system.
- Disallow userspace to change the LSM credentials via
/proc/self/attr when the task's credentials are already overridden.
The change was made in procfs because all the LSM folks agreed this
was the Right Thing To Do and duplicating it across each LSM was
going to be annoying"

Char/Misc patches for 5.2-rc1 - part 2
Here is the "real" big set of char/misc driver patches for 5.2-rc1
Loads of different driver subsystem stuff in here, all over the places:

- extcon driver updates
- intel_th driver updates
- mei driver updates
- coresight driver updates
- soundwire driver cleanups and updates
- fastrpc driver updates
- other minor driver updates
- chardev minor fixups
Feels like this tree is getting to be a dumping ground of "small driver
subsystems" these days. Which is fine with me, if it makes things

All of these have been in linux-next for a while with no reported

Staging / IIO driver patches for 5.2-rc1
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.
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.
All of these have been in linux-next for a while with no reported
issues, other than an odd gcc warning for one of the new drivers that
should be fixed up soon.

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.
All of these have been in linux-next for a while with no reported
issues, other than an odd gcc warning for one of the new drivers that
should be fixed up soon"
[ I fixed up the warning myself - Linus ]

Driver core/kobject patches for 5.2-rc1
Here is the "big" set of driver core patches for 5.2-rc1
There are a number of ACPI patches in here as well, as Rafael said they
should go through this tree due to the driver core changes they
required. They have all been acked by the ACPI developers.
There are also a number of small subsystem-specific changes in here, due
to some changes to the kobject core code. Those too have all been acked
by the various subsystem maintainers.
As for content, it's pretty boring outside of the ACPI changes:
- spdx cleanups
- kobject documentation updates
- default attribute groups for kobjects
- other minor kobject/driver core fixes
All have been in linux-next for a while with no reported issues.

Wimplicit-fallthrough patches for 5.2-rc1
Hi Linus, This is my very first pull-request. I've been working full-time as a kernel developer for more than two years now. During this time I've been fixing bugs reported by Coverity all over the tree and, as part of my work, I'm also contributing to the KSPP. My work in the kernel community has been supervised by Greg KH and Kees Cook. OK. So, after the quick introduction above, please, pull the following patches that mark switch cases where we are expecting to fall through. These patches are part of the ongoing efforts to enable -Wimplicit-fallthrough. They have been ignored for a long time (most of them more than 3 months, even after pinging multiple times), which is the reason why I've created this tree. Most of them have been baking in linux-next for a whole development cycle. And with Stephen Rothwell's help, we've had linux-next nag-emails going out for newly introduced code that triggers -Wimplicit-fallthrough to avoid gaining more of these cases while we work to remove the ones that are already present. I'm happy to let you know that 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. I'm auditing every case; I take a look into the code and analyze it in order to determine if I'm dealing with an actual bug or a false positive, as explained here: https://lore.kernel.org/lkml/c2fad584-1705-a5f2-d63c-824e9b96cf50@embeddedor.com/ While working on this, I've found and fixed the following missing break/return bugs, some of them introduced more than 5 years ago: |

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 |

net: macb: Change interrupt and napi enable order in open
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.

Instead store a flag in driver private data which indicates if offloads apply to a shared block at block binding time.

Merge branch 'of_get_mac_address-ERR_PTR-fixes'
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. Fourth patch fixes warning reported by kbuild test robot. ==================== Tested-by: Geert Uytterhoeven <geert+renesas@glider.be> Tested-by: Leonard Crestez <leonard.crestez@nxp.com> Signed-off-by: David S.

net: ethernet: support of_get_mac_address new ERR_PTR error
There was NVMEM support added to of_get_mac_address, so it could now
return ERR_PTR encoded error values, so we need to adjust all current
users of of_get_mac_address to this new fact.
While at it, remove superfluous is_valid_ether_addr as the MAC address
returned from of_get_mac_address is always valid and checked by
is_valid_ether_addr anyway.

net: usb: smsc: fix warning reported by kbuild test robot
This patch fixes following warning reported by kbuild test robot:
In function ‘memcpy’,
inlined from ‘smsc75xx_init_mac_address’ at drivers/net/usb/smsc75xx.c:778:3,
inlined from ‘smsc75xx_bind’ at drivers/net/usb/smsc75xx.c:1501:2:
./include/linux/string.h:355:9: warning: argument 2 null where non-null expected [-Wnonnull]
return __builtin_memcpy(p, q, size);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/usb/smsc75xx.c: In function ‘smsc75xx_bind’:
./include/linux/string.h:355:9: note: in a call to built-in function ‘__builtin_memcpy’
I've replaced the offending memcpy with ether_addr_copy, because I'm
100% sure, that of_get_mac_address can't return NULL as it returns valid
pointer or ERR_PTR encoded value, nothing else.
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.

net: dsa: sja1105: Fix status initialization in sja1105_get_ethtool_stats
Clang warns:

braces around initialization of subobject [-Wmissing-braces]
struct sja1105_port_status status = {0};

1 warning generated.
One way to fix these warnings is to add additional braces like Clang
suggests; however, there has been a bit of push back from some
maintainers[1][2], who just prefer memset as it is unambiguous, doesn't
depend on a particular compiler version[3], and properly initializes all
subobjects. Do that here so there are no more warnings.

vrf: sit mtu should not be updated when vrf netdev is the link
VRF netdev mtu isn't typically set and have an mtu of 65536. When the link of a tunnel is set, the tunnel mtu is changed from 1480 to the link mtu minus tunnel header. In the case of VRF netdev is the link, then the tunnel mtu becomes 65516. So, fix it by not setting the tunnel mtu in this case.

We also want to enable in-kernel pacing, which is possible thanks to EDT model, since each sendmsg() can provide a timestamp for the skbs. We have to change sch_fq to enable feeding packets in arbitrary EDT order, and make sure that packet classification do not trust unconnected sockets.

net_sched: sch_fq: handle non connected flows
FQ packet scheduler assumed that packets could be classified based on their owning socket. This means that if a UDP server uses one UDP socket to send packets to different destinations, packets all land in one FQ flow. This is unfair, since each TCP flow has a unique bucket, meaning that in case of pressure (fully utilised uplink), TCP flows have more share of the bandwidth. If we instead detect unconnected sockets, we can use a stochastic hash based on the 4-tuple hash. This also means a QUIC server using one UDP socket will properly spread the outgoing packets to different buckets, and in-kernel pacing based on EDT model will no longer risk having big rb-tree on one flow. Note that UDP application might provide the skb->hash in an ancillary message at sendmsg() time to avoid the cost of a dissection in fq packet scheduler.

net_sched: sch_fq: do not assume EDT packets are ordered
TCP stack makes sure packets for a given flow are monotically increasing, but we want to allow UDP packets to use EDT as well, so that QUIC servers can use in-kernel pacing. This patch adds a per-flow rb-tree on which packets might be stored. We still try to use the linear list for the typical cases where packets are queued with monotically increasing skb->tstamp, since queue/dequeue packets on a standard list is O(1). Note that the ability to store packets in arbitrary EDT order will allow us to implement later a per TCP socket mechanism adding delays (with jitter eventually) and reorders, to implement convenient network emulators.
