[ Upstream commit 9991bb84b2 ]
When creating an FS_MODIFY event on inode itself (not on parent)
the file_name argument should be NULL.
The change to send a non NULL name to inode itself was done on purpuse
as part of another commit, as Tejun writes: "...While at it, supply the
target file name to fsnotify() from kernfs_node->name.".
But this is wrong practice and inconsistent with inotify behavior when
watching a single file. When a child is being watched (as opposed to the
parent directory) the inotify event should contain the watch descriptor,
but not the file name.

If kobject_del() is invoked by kobject_cleanup() to delete the
target kobject, it may cause its parent kobject to be freed
before invoking the target kobject's ->release() method, which
effectively means freeing the parent before dealing with the
child entirely.
That is confusing at best and it may also lead to functional
issues if the callers of kobject_cleanup() are not careful enough
about the order in which these calls are made, so avoid the
problem by making kobject_cleanup() drop the last reference to
the target kobject's parent at the end, after invoking the target
kobject's ->release() method.

[ Upstream commit 2a7e32d054 ]
The pci_cfg_wait queue is used to prevent user-space config accesses to
devices while they are recovering from reset.
Previously we used these operations on pci_cfg_wait:
__add_wait_queue(&pci_cfg_wait, ...)
__remove_wait_queue(&pci_cfg_wait, ...)
wake_up_all(&pci_cfg_wait)
The wake_up acquires the wait queue lock, but the add and remove do not.
Originally these were all protected by the pci_lock, but cdcb33f982
("PCI: Avoid possible deadlock on pci_lock and p->pi_lock"), moved
wake_up_all() outside pci_lock, so it could race with add/remove
operations, which caused occasional kernel panics, e.g., during vfio-pci
hotplug/unplug testing:
Unable to handle kernel read from unreadable memory at virtual address ffff802dac469000
Resolve this by using wait_event() instead of __add_wait_queue() and
__remove_wait_queue(). The wait queue lock is held by both wait_event()
and wake_up_all(), so it provides mutual exclusion.

The data fork scrubber calls filemap_write_and_wait to flush dirty pages
and delalloc reservations out to disk prior to checking the data fork's
extent mappings. Unfortunately, this means that scrub can consume the
EIO/ENOSPC errors that would otherwise have stayed around in the address
space until (we hope) the writer application calls fsync to persist data
and collect errors. The end result is that programs that wrote to a
file might never see the error code and proceed as if nothing were
wrong.
xfs_scrub is not in a position to notify file writers about the
writeback failure, and it's only here to check metadata, not file
contents. Therefore, if writeback fails, we should stuff the error code
back into the address space so that an fsync by the writer application
can pick that up.

[ Upstream commit f0a5e4d7a5 ]
YangYuxi is reporting that connection reuse
is causing one-second delay when SYN hits
existing connection in TIME_WAIT state.
Such delay was added to give time to expire
both the IPVS connection and the corresponding
conntrack. This was considered a rare case
at that time but it is causing problem for
some environments such as Kubernetes.
As nf_conntrack_tcp_packet() can decide to
release the conntrack in TIME_WAIT state and
to replace it with a fresh NEW conntrack, we
can use this to allow rescheduling just by
tuning our check: if the conntrack is
confirmed we can not schedule it to different
real server and the one-second delay still
applies but if new conntrack was created,
we are free to select new real server without
any delays.
YangYuxi lists some of the problem reports:
- One second connection delay in masquerading mode:
https://marc.info/?t=151683118100004&r=1&w=2
- IPVS low throughput #70747

- Apache Bench can fill up ipvs service proxy in seconds #544https://github.com/cloudnativelabs/kube-router/issues/544

ib_unregister_device_queued() can only be used by drivers using the new
dealloc_device callback flow, and it has a safety WARN_ON to ensure
drivers are using it properly.
However, if unregister and register are raced there is a special
destruction path that maintains the uniform error handling semantic of
'caller does ib_dealloc_device() on failure'. This requires disabling the
dealloc_device callback which triggers the WARN_ON.
Instead of using NULL to disable the callback use a special function
pointer so the WARN_ON does not trigger.

a mistake:

~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~
In this driver, it is intentional, so add a cast to hide the false-positive
warning. It appears to be the only instance of this warning at the moment.
