If we fault due to authentication, we invalidate the service ticket we
have and request a new one - the idea being that if a service rejected
our authorizer, it must have expired, despite mon_client's attempts at
periodic renewal. (The other possibility is that our ticket is too new
and the service hasn't gotten it yet, in which case invalidating isn't
necessary but doesn't hurt.)
Invalidating just the service ticket is not enough, though. If we
assume a failure on mon_client's part to renew a service ticket, we
have to assume the same for the AUTH ticket. If our AUTH ticket is
bad, we won't get any service tickets no matter how hard we try, so
invalidate AUTH ticket along with the service ticket.

Back in 2013, commit 4b8e8b5d78b8 ("libceph: fix authorizer
invalidation") tried to fix authorizer invalidation issues by clearing
validity field. However, nothing ever consults this field, so it
doesn't force us to request any new secrets in any way and therefore we
never get out of the exponential backoff mode:
[ 129.973812] libceph: osd2 192.168.122.1:6810 connect authorization failure
[ 130.706785] libceph: osd2 192.168.122.1:6810 connect authorization failure

[ 137.706598] libceph: osd2 192.168.122.1:6810 connect authorization failure

There are a number of problems with revoking a "was sending" message:
(1) We never make any attempt to revoke data - only kvecs contibute to
con->out_skip. However, once the header (envelope) is written to the
socket, our peer learns data_len and sets itself to expect at least
data_len bytes to follow front or front+middle. If ceph_msg_revoke()
is called while the messenger is sending message's data portion,
anything we send after that call is counted by the OSD towards the now
revoked message's data portion. The effects vary, the most common one
is the eventual hang - higher layers get stuck waiting for the reply to
the message that was sent out after ceph_msg_revoke() returned and
treated by the OSD as a bunch of data bytes. This is what Matt ran
into.
(2) Flat out zeroing con->out_kvec_bytes worth of bytes to handle kvecs
is wrong. If ceph_msg_revoke() is called before the tag is sent out or
while the messenger is sending the header, we will get a connection
reset, either due to a bad tag (0 is not a valid tag) or a bad header
CRC, which kind of defeats the purpose of revoke. Currently the kernel
client refuses to work with header CRCs disabled, but that will likely
change in the future, making this even worse.
(3) con->out_skip is not reset on connection reset, leading to one or
more spurious connection resets if we happen to get a real one between
con->out_skip is set in ceph_msg_revoke() and before it's cleared in
write_partial_skip().
Fixing (1) and (3) is trivial. The idea behind fixing (2) is to never
zero the tag or the header, i.e. send out tag+header regardless of when
ceph_msg_revoke() is called. That way the header is always correct, no
unnecessary resets are induced and revoke stands ready for disabled
CRCs. Since ceph_msg_revoke() rips out con->out_msg, introduce a new
"message out temp" and copy the header into it before sending.

When receiving -EOLDSNAP from OSD, we need to re-send corresponding

The basic idea of AIO support is simple, just call kiocb::ki_complete()
in OSD request's complete callback. But there are several special cases.
when IO span multiple objects, we need to wait until all OSD requests
are complete, then call kiocb::ki_complete(). Error handling in this case
is tricky too. For simplify, AIO both span multiple objects and extends
i_size are not allowed.
Another special case is check EOF for reading (other client can write to
the file and extend i_size concurrently). For simplify, the direct-IO/AIO
code path does do the check, fallback to normal syn read instead.

Raw Packet QP, unlike other QP types, has no matching mlx5_core_qp
object but rather it is built of RQ/SQ/TIR/TIS/TD mlx5_core object.

other QPs, we allocate separate buffers in the user-space and pass
the address of each one of them separately to the kernel.

The rdma netlink local service registers a handler to handle RESOLVE
response and another handler to handle SET_TIMEOUT request. The first
thing these handlers do is to call netlink_capable() to check the
access right of the received skb to make sure that the sender has root
access. Under normal conditions, such responses and requests will be
directly forwarded to the handlers without going through the netlink_dump
pathway (see ibnl_rcv_msg() in drivers/infiniband/core/netlink.c).
However, a user application could send a RESOLVE request (not response)
to the local service, which will fall into the netlink_dump pathway,
where a new skb will be created without initializing the control block.
This new skb will be eventually forwarded to the local service RESOLVE
response handler. Unfortunately, netlink_capable() will cause general
protection fault if the skb's control block is not initialized. This
patch will address the problem by checking the skb first.

Currently ALSA timer device doesn't take the disconnection into
account very well; it merely unlinks the timer device at disconnection
callback but does nothing else. Because of this, when an application
accessing the timer device is disconnected, it may release the
resource before actually closed. In most cases, it results in a
warning message indicating a leftover timer instance like:
ALSA: timer xxxx is busy?
But basically this is an open race.
This patch tries to address it. The strategy is like other ALSA
devices: namely,
- Manage card's refcount at each open/close
- Wake up the pending tasks at disconnection
- Check the shutdown flag appropriately at each possible call
Note that this patch has one ugly hack to handle the wakeup of pending
tasks. It'd be cleaner to introduce a new disconnect op to
snd_timer_instance ops. But since it would lead to internal ABI
breakage and it eventually increase my own work when backporting to
stable kernels, I took a different path to implement locally in
timer.c. A cleanup patch will follow at next for 4.5 kernel.

Commit d1cd21427747 ("pwm: Set enable state properly on failed call to

PWM devices. Since that mutex is acquired in pwm_set_polarity() and in
pwm_enable() and might potentially block, all PWM devices effectively
become "might sleep".
It's rather pointless to keep the .can_sleep field around, but given
that there are external users let's postpone the removal for the next
release cycle.

above obj-y := core.o, which doesn't work: the += directives
need to add something to the build and doesn't work if obj-y
is not set first, so move the obj-y to be on top and everything
builds nicely again.

Pull more power management and ACPI updates from Rafael Wysocki:
"This includes fixes on top of the previous batch of PM+ACPI updates
and some new material as well.
From the new material perspective the most significant are the driver
core changes that should allow USB devices to stay suspended over
system suspend/resume cycles if they have been runtime-suspended
already beforehand. Apart from that, ACPICA is updated to upstream
revision 20160108 (cosmetic mostly, but including one fixup on top of
the previous ACPICA update) and there are some devfreq updates the
didn't make it before (due to timing).
A few recent regressions are fixed, most importantly in the cpuidle
menu governor and in the ACPI backlight driver and some x86 platform
drivers depending on it.
Some more bugs are fixed and cleanups are made on top of that.
Specifics:
- Modify the driver core and the USB subsystem to allow USB devices
to stay suspended over system suspend/resume cycles if they have
been runtime-suspended already beforehand and fix some bugs on top
of these changes (Tomeu Vizoso, Rafael Wysocki).
- Update ACPICA to upstream revision 20160108, including updates of
the ACPICA's copyright notices, a code fixup resulting from a
regression fix that was necessary in the upstream code only (the
regression fixed by it has never been present in Linux) and a
compiler warning fix (Bob Moore, Lv Zheng).
- Fix a recent regression in the cpuidle menu governor that broke it
on practically all architectures other than x86 and make a couple
of optimizations on top of that fix (Rafael Wysocki).
- Clean up the selection of cpuidle governors depending on whether or
not the kernel is configured for tickless systems (Jean Delvare).
- Revert a recent commit that introduced a regression in the ACPI
backlight driver, address the problem it attempted to fix in a
different way and revert one more cosmetic change depending on the
problematic commit (Hans de Goede).
- Add two more ACPI backlight quirks (Hans de Goede).
- Fix a few minor problems in the core devfreq code, clean it up a
bit and update the MAINTAINERS information related to it (Chanwoo
Choi, MyungJoo Ham).
- Improve an error message in the ACPI fan driver (Andy Lutomirski).
- Fix a recent build regression in the cpupower tool (Shreyas
Prabhu)"

Pull ARM SoC multiplatform code updates from Arnd Bergmann:
"This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings
several of the more minor and older platforms we have closer to
multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0
and realview Much of this is moving around header files from old mach
directories, but there are also some cleanup patches of debug_ll
(lowlevel debug per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts"
