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:
- thunderbolt driver updates
- habanalabs driver updates
- nvmem driver updates
- 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
easier for those subsystem maintainers.
All of these have been in linux-next for a while with no reported
issues.

gfs2: Fix lru_count going negative
Under certain conditions, lru_count may drop below zero resulting in
a large amount of log spam like this:
vmscan: shrink_slab: gfs2_dump_glock+0x3b0/0x630 [gfs2] \
negative objects to delete nr=-1
This happens as follows:
1) A glock is moved from lru_list to the dispose list and lru_count is
decremented.
2) The dispose function calls cond_resched() and drops the lru lock.
3) Another thread takes the lru lock and tries to add the same glock to
lru_list, checking if the glock is on an lru list.
4) It is on a list (actually the dispose list) and so it avoids
incrementing lru_count.
5) The glock is moved to lru_list.
5) The original thread doesn't dispose it because it has been re-added
to the lru list but the lru_count has still decreased by one.
Fix by checking if the LRU flag is set on the glock rather than checking
if the glock is on some list and rearrange the code so that the LRU flag
is added/removed precisely when the glock is added/removed from lru_list.

Char/Misc patches for 5.2-rc1 - part 1
This is the first pull request for the char/misc driver tree for 5.2-rc1 This contains only a small number of bugfixes that would have gone to you for 5.1-rc8 if that had happened, but instead I let them sit in linux-next for an extra week just "to be sure". The "big" patch here is for hyper-v, fixing a bug in their sysfs files that could cause big problems. The others are all small fixes, resolving reported issues that showed up in 5.1-rcs, plus some odd 'static' cleanups for the phy drivers that really should have waited for -rc1. Most of these are tagged for the stable trees, so 5.1 will pick them up. All of these have been in linux-next for a while, with no reported issues.

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.

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.

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:

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.

net: mvpp2: cls: fix less than zero check on a u32 variable
The signed return from the call to mvpp2_cls_c2_port_flow_index is being
assigned to the u32 variable c2.index and then checked for a negative
error condition which is always going to be false. Fix this by assigning
the return to the int variable index and checking this instead.

RDMA/ipoib: Allow user space differentiate between valid dev_port
Systemd triggers the following warning during IPoIB device load:
mlx5_core 0000:00:0c.0 ib0: "systemd-udevd" wants to know my dev_id.
Should it look at dev_port instead?
See Documentation/ABI/testing/sysfs-class-net for more info.
This is caused due to user space attempt to differentiate old systems
without dev_port and new systems with dev_port. In case dev_port will be
zero, the systemd will try to read dev_id instead.
There is no need to print a warning in such case, because it is valid
situation and it is needed to ensure systemd compatibility with old
kernels.

Merge branch 'fc-quic-pacing'
Eric Dumazet says: ==================== net_sched: sch_fq: enable in-kernel pacing for QUIC servers Willem added GSO support to UDP stack, greatly improving performance of QUIC servers. 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. Note that this patch series also is a prereq for a future TCP change enabling per-flow delays/reorders/losses to implement high performance TCP emulators. ==================== Signed-off-by: David S.

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.

IB/core, ipoib: Do not overreact to SM LID change event
When IPoIB receives an SM LID change event, it reacts by flushing its path record cache and rejoining multicast groups. This is the same behavior it performs when it receives a reregistration event. This behavior is unnecessary as an SM may have database backup or synchronization mechanisms which permit the SM location or LID to change without loss of multicast membership and without impact to path records. Both opensm and the OPA FM issue reregistration events if a new SM is started (or restarted with a new config) or an SM event occurs which results in loss of multicast membership records by the SM (such as opensm failover) or the SM encounters new nodes with Active ports (such as after joining 2 fabrics by connecting switches via ISLs). Hence this event can be depended on as the trigger for IPoIB cache and multicast flushing. It appears that some drivers, such as qib, and hfi1 issue the IB_EVENT_SM_CHANGE but other drivers such as mlx4 and mlx5 do not. Empirical testing on Mellanox EDR using ibv_asyncwatch has confirmed that Mellanox EDR HCAs do not generate SM change events and that opensm does generate reregistration. An SM LID change event is generated by the mentioned drivers to reflect that sm_lid and/or sm_sl in the local port info has changed. The intent of this event is to permit applications and ULPs which have a local copy of this information (or an address handle using it) to update their information. The intent is that the reregistration event (caused by the SM via a bit in Set(PortInfo)) be used to inform nodes that they need to rejoin multicast groups, resubscribe for notices and potentially update path records. When an SM migrates or fails over, a SM LID change event can occur. In response IPoIB discards path records and multicast membership and loses connectivity until these records are restored via SA requests. In very large fabrics, it may take minutes for the SM to be ready and for the SA responses to be supplied. This can result in undesirable and unnecessary IPoIB connectivity impacts. It also can result in an unnecessary storm of SA queries from all nodes in a cluster potentially followed by yet another storm if the SM issues the reregistration request. The fact the Mellanox HCAs do not even generate this event, is further evidence that on modern IB fabrics there will be no ill side effects from the proposed changes below to reduce the reaction by 3 kernel components to this event. So these changes should be benign for Mellanox IB fabrics and will benefit OPA fabrics while also making ib_core and ULP behavor "correct" as intended by the IBTA spec and kernel RDMA event APIs. Address these issues by removing IB_EVENT_SM_CHANGE handling from ipoib. IPoIB does not locally store sm_lid nor sm_sl, so it does not need to do anything on SM LID change. IPoIB makes use of other ib_core components to issue SA requests for it and those components correctly track SM LID and SM LID changes. Also in ib_core multicast handling, remove the test for IB_EVENT_SM_CHANGE. This code is moving all multicast groups to the error state, which will trigger rejoins. This code is used by IPoIB as well as the connection manager and other clients of multicast groups. This kernel module centralizes group membership status and joins since a node can only join a given group once but multiple ULPs or applications may want to join the same group. It makes use of the sa_query.c component in ib_core, which correctly trackes SM LID and SL. This component does not track SM LID nor SL itself and hence need not react to their changes. Similarly in the ib_core cache code remove the handling for the IB_EVENT_SM_CHANGE. In this function. The ib_cache_update function which is ultimately called is updating local copies of the pkey table, gid table and lmc. It does not update nor retain sm_lid nor sm_sl. As such it does not need to be called on an SM LID change. It technically also does not need to be called on a reregistration. The LID_CHANGE, PKEY_CHANGE, GID_CHANGE and port state change events (PORT_ERR, PORT_ACTICE) should be sufficient triggers. It is worth noting that the alternative of simply having the hfi1 and qib drivers not generate the SM LID change event was explored. While this would duplicate what Mellanox drivers do now, it is not the correct behavior and removes the ability for an SM to migrate without requiring reregistration. Since both opensm and OPA SM have mechanisms to backup or synchronize registration information, it is desirable to let them perform SM migrations (with LID or SL changes) without requiring reregistration when they deem it appropriate.

Merge tag 'xfs-5.2-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"Here's a big pile of new stuff for XFS for 5.2. XFS has grown the
ability to report metadata health status to userspace after online
fsck checks the filesystem. The online metadata checking code is (I
really hope) feature complete with the addition of checks for the
global fs counters, though it'll remain EXPERIMENTAL for now.
There are also fixes for thundering herds of writeback completions and
some other deadlocks, fixes for theoretical integer overflow attacks
on space accounting, and removal of the long-defunct 'mntpt' option
which was deprecated in the mid-2000s and (it turns out) totally
broken since 2011 (and nobody complained...).
Summary:
- Fix some more buffer deadlocks when performing an unmount after a
hard shutdown.
- Fix some minor space accounting issues.
- Fix some use after free problems.
- Make the (undocumented) FITRIM behavior consistent with other
filesystems.
- Embiggen the xfs geometry ioctl's data structure.
- Introduce a new AG geometry ioctl.
- Introduce a new online health reporting infrastructure and ioctl
for userspace to query a filesystem's health status.
- Enhance online scrub and repair to update the health reports.
- Reduce thundering herd problems when writeback io completes.
- Fix some transaction reservation type errors.
- Fix integer overflow problems with delayed alloc reservation
counters.
- Fix some problems where we would exit to userspace without

Merge tag 'for-5.2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"This time the majority of changes are cleanups, though there's still a
number of changes of user interest.
User visible changes:
- better read time and write checks to catch errors early and before
writing data to disk (to catch potential memory corruption on data
that get checksummed)
- qgroups + metadata relocation: last speed up patch int the series
to address the slowness, there should be no overhead comparing
balance with and without qgroups
- FIEMAP ioctl does not start a transaction unnecessarily, this can
result in a speed up and less blocking due to IO
- LOGICAL_INO (v1, v2) does not start transaction unnecessarily, this
can speed up the mentioned ioctl and scrub as well
- fsync on files with many (but not too many) hardlinks is faster,
finer decision if the links should be fsynced individually or
completely
- send tries harder to find ranges to clone
- trim/discard will skip unallocated chunks that haven't been touched
since the last mount
Fixes:
- send flushes delayed allocation before start, otherwise it could
miss some changes in case of a very recent rw->ro switch of a
subvolume
- fix fallocate with qgroups that could lead to space accounting
underflow, reported as a warning
- trim/discard ioctl honours the requested range
- starting send and dedupe on a subvolume at the same time will let
only one of them succeed, this is to prevent changes that send
could miss due to dedupe; both operations are restartable
Core changes:
- more tree-checker validations, errors reported by fuzzing tools:
- device item
- inode item
- block group profiles
- tracepoints for extent buffer locking
- async cow preallocates memory to avoid errors happening too deep in
the call chain
- metadata reservations for delalloc reworked to better adapt in
many-writers/low-space scenarios
- improved space flushing logic for intense DIO vs buffered workloads
- lots of cleanups
- removed unused struct members
- redundant argument removal
- properties and xattrs
- extent buffer locking
- selftests
- use common file type conversions
- many-argument functions reduction"

net: hns3: unify the page reusing for page size 4K and 64K
When page size is 64K, RX buffer is currently not reused when the page_offset is moved to last buffer. This patch adds checking to decide whether the buffer page can be reused when last_offset is moved beyond last offset. If the driver is the only user of page when page_offset is moved to beyond last offset, then buffer can be reused and page_offset is set to zero.
