kasan, arm64: fix pointer tags in KASAN reports
As of the "arm64: expose FAR_EL1 tag bits in siginfo" patch, the address that is passed to report_tag_fault has pointer tags in the format of 0x0X, while KASAN uses 0xFX format (note the difference in the top 4 bits). Fix up the pointer tag for kernel pointers in do_tag_check_fault by setting them to the same value as bit 55. Explicitly use __untagged_addr() instead of untagged_addr(), as the latter doesn't affect TTBR1 addresses. Fixes: |

nvmet: set right status on error in id-ns handler
The function nvmet_execute_identify_ns() doesn't set the status if call to nvmet_find_namespace() fails. In that case we set the status of the request to the value return by the nvmet_copy_sgl(). Set the status to NVME_SC_INVALID_NS and adjust the code such that request will have the right status on nvmet_find_namespace() failure.

nvme-tcp: avoid request double completion for concurrent nvme_tcp_timeout
Each name space has a request queue, if complete request long time, multi request queues may have time out requests at the same time, nvme_tcp_timeout will execute concurrently. Multi requests in different request queues may be queued in the same tcp queue, multi nvme_tcp_timeout may call nvme_tcp_stop_queue at the same time. The first nvme_tcp_stop_queue will clear NVME_TCP_Q_LIVE and continue stopping the tcp queue(cancel io_work), but the others check NVME_TCP_Q_LIVE is already cleared, and then directly complete the requests, complete request before the io work is completely canceled may lead to a use-after-free condition.

nvme: check the PRINFO bit before deciding the host buffer length
According to NVMe spec v1.4, section 8.3.1, the PRINFO bit and the metadata size play a vital role in deteriming the host buffer size.

pinctrl: qcom: Don't clear pending interrupts when enabling
In Linux, if a driver does disable_irq() and later does enable_irq() on its interrupt, I believe it's expecting these properties: * If an interrupt was pending when the driver disabled then it will still be pending after the driver re-enables. * If an edge-triggered interrupt comes in while an interrupt is disabled it should assert when the interrupt is re-enabled. If you think that the above sounds a lot like the disable_irq() and enable_irq() are supposed to be masking/unmasking the interrupt instead of disabling/enabling it then you've made an astute observation. Specifically when talking about interrupts, "mask" usually means to stop posting interrupts but keep tracking them and "disable" means to fully shut off interrupt detection. It's unfortunate that this is so confusing, but presumably this is all the way it is for historical reasons. Perhaps more confusing than the above is that, even though clients of IRQs themselves don't have a way to request mask/unmask vs. disable/enable calls, IRQ chips themselves can implement both. ...and yet more confusing is that if an IRQ chip implements disable/enable then they will be called when a client driver calls disable_irq() / enable_irq(). It does feel like some of the above could be cleared up. However, without any other core interrupt changes it should be clear that when an IRQ chip gets a request to "disable" an IRQ that it has to treat it like a mask of that IRQ. In any case, after that long interlude you can see that the "unmask and clear" can break things. Maulik tried to fix it so that we no longer did "unmask and clear" in commit |

pinctrl: qcom: No need to read-modify-write the interrupt status
When the Qualcomm pinctrl driver wants to Ack an interrupt, it does a read-modify-write on the interrupt status register. On some SoCs it makes sure that the status bit is 1 to "Ack" and on others it makes sure that the bit is 0 to "Ack". Presumably the first type of interrupt controller is a "write 1 to clear" type register and the second just let you directly set the interrupt status register. As far as I can tell from scanning structure definitions, the interrupt status bit is always in a register by itself. Thus with both types of interrupt controllers it is safe to "Ack" interrupts without doing a read-modify-write. We can do a simple write. It should be noted that if the interrupt status bit _was_ ever in a register with other things (like maybe status bits for other GPIOs): a) For "write 1 clear" type controllers then read-modify-write would be totally wrong because we'd accidentally end up clearing interrupts we weren't looking at. b) For "direct set" type controllers then read-modify-write would also be wrong because someone setting one of the other bits in the register might accidentally clear (or set) our interrupt. I say this simply to show that the current read-modify-write doesn't provide any sort of "future proofing" of the code. In fact (for "write 1 clear" controllers) the new code is slightly more "future proof" since it would allow more than one interrupt status bits to share a register. NOTE: this code fixes no bugs--it simply avoids an extra register read.

There's currently a comment in the code saying function 0 is GPIO. Instead of hardcoding it, let's add a member where an SoC can specify it.

This occurred because we freed our backref node in
btrfs_backref_error_cleanup(), but then tried to free it again in
btrfs_backref_release_cache(). This is because
btrfs_backref_release_cache() will cycle through all of the
cache->leaves nodes and free them up. However
btrfs_backref_error_cleanup() freed the backref node with
btrfs_backref_free_node(), which simply kfree()d the backref node
without unlinking it from the cache. Change this to a
btrfs_backref_drop_node(), which does the appropriate cleanup and
removes the node from the cache->leaves list, so when we go to free the
remaining cache we don't trip over items we've already dropped.

udf: fix the problem that the disc content is not displayed
When the capacity of the disc is too large (assuming the 4.7G specification), the disc (UDF file system) will be burned multiple times in the windows (Multisession Usage). When the remaining capacity of the CD is less than 300M (estimated value, for reference only), open the CD in the Linux system, the content of the CD is displayed as blank (the kernel will say "No VRS found"). Windows can display the contents of the CD normally. Through analysis, in the "fs/udf/super.c": udf_check_vsd function, the actual value of VSD_MAX_SECTOR_OFFSET may be much larger than 0x800000. According to the current code logic, it is found that the type of sbi->s_session is "__s32", when the remaining capacity of the disc is less than 300M (take a set of test values: sector=3154903040, sbi->s_session=1540464, sb->s_blocksize_bits=11 ), the calculation result of "sbi->s_session << sb->s_blocksize_bits" will overflow. Therefore, it is necessary to convert the type of s_session to "loff_t" (when udf_check_vsd starts, assign a value to _sector, which is also converted in this way), so that the result will not overflow, and then the content of the disc can be displayed normally.

drm/i915: Check for rq->hwsp validity after acquiring RCU lock
Since we allow removing the timeline map at runtime, there is a risk that rq->hwsp points into a stale page. To control that risk, we hold the RCU read lock while reading *rq->hwsp, but we missed a couple of important barriers. First, the unpinning / removal of the timeline map must be after all RCU readers into that map are complete, i.e. after an rcu barrier (in this case courtesy of call_rcu()). Secondly, we must make sure that the rq->hwsp we are about to dereference under the RCU lock is valid. In this case, we make the rq->hwsp pointer safe during i915_request_retire() and so we know that rq->hwsp may become invalid only after the request has been signaled. Therefore is the request is not yet signaled when we acquire rq->hwsp under the RCU, we know that rq->hwsp will remain valid for the duration of the RCU read lock. This is a very small window that may lead to either considering the request not completed (causing a delay until the request is checked again, any wait for the request is not affected) or dereferencing an invalid pointer.

drm/i915/gt: Prevent use of engine->wa_ctx after error
On error we unpin and free the wa_ctx.vma, but do not clear any of the derived flags. During lrc_init, we look at the flags and attempt to dereference the wa_ctx.vma if they are set. To protect the error path where we try to limp along without the wa_ctx, make sure we clear those flags! Reported-by: Matt Roper <matthew.d.roper@intel.com> Fixes: |

drm/vc4: Unify PCM card's driver_name
User-space ALSA matches a card's driver name against an internal list of
aliases in order to select the correct configuration for the system.
When the driver name isn't defined, the match is performed against the
card's name.
With the introduction of RPi4 we now have two HDMI ports with two
distinct audio cards. This is reflected in their names, making them
different from previous RPi versions. With this, ALSA ultimately misses
the board's configuration on RPi4.
In order to avoid this, set "card->driver_name" to "vc4-hdmi"
unanimously.

ALSA: usb-audio: Avoid implicit feedback on Pioneer devices
For addressing the regression on Pioneer devices, we recently
corrected the quirk code to enable the implicit feedback mode on those
devices properly. However, the devices still showed problems with the
full duplex operations with JACK, and after debug sessions, we figured
out that the older kernels that had worked with JACK also didn't use
the implicit feedback mode at all although they had the quirk code to
enable it; instead, the old code worked just to skip the normal sync
endpoint setup that would have been detected without it. IOW, what
broke without the implicit-fb quirk in the past was the application of
the normal sync endpoint that is actually the capture data endpoint on
these devices.
This patch covers the overseen piece: it modifies the quirk code again
not to enable the implicit feedback mode but just to make the driver
skipping the sync endpoint detection. This made the driver working
with JACK full-duplex mode again.
Still it's not quite clear why the implicit feedback doesn't work on
those devices yet; maybe it's about some issues in the URB setup. But
at least, with this patch, the driver should work in the level of the
older kernels again.

ALSA: usb-audio: Set sample rate for all sharing EPs on UAC1
The UAC2/3 sample rate setup is based on the clock node, which is
usually shared in the interface, and can't be re-setup without
deselecting the interface once, and that's how the current code
behaves. OTOH, the sample rate setup of UAC1 is per endpoint, hence
we basically need to call for each endpoint usage even if those share
the same interface.
This patch fixes the behavior of UAC1 to call always
snd_usb_init_sample_rate() in snd_usb_endpoint_configure().

ALSA: usb-audio: Fix UAC1 rate setup for secondary endpoints
The current sample rate setup function for UAC1 assumes only the first endpoint retrieved from the interface:altset pair, but the rate set up may be needed also for the secondary endpoint. Also, retrieving the endpoint number from the interface descriptor is redundant; we have already the target endpoint in the given audioformat object. This patch simplifies the code and corrects the target endpoint as described in the above. It simply refers to fmt->endpoint directly. Also, this patch drops the pioneer_djm_set_format_quirk() that is caleld from snd_usb_set_format_quirk(); this function does the sample rate setup but for the capture endpoint (0x82), and that's exactly what the change above fixes.

drm/i915/hdcp: Update CP property in update_pipe
When crtc state need_modeset is true it is not necessary it is going to be a real modeset, it can turns to be a fastset instead of modeset. This turns content protection property to be DESIRED and hdcp update_pipe left with property to be in DESIRED state but actual hdcp->value was ENABLED. This issue is caught with DP MST setup, where we have multiple connector in same DP_MST topology. When disabling HDCP on one of DP MST connector leads to set the crtc state need_modeset to true for all other crtc driving the other DP-MST topology connectors. This turns up other DP MST connectors CP property to be DESIRED despite the actual hdcp->value is ENABLED. Above scenario fails the DP MST HDCP IGT test, disabling HDCP on one MST stream should not cause to disable HDCP on another MST stream on same DP MST topology. v2: - Fixed connector->base.registration_state == DRM_CONNECTOR_REGISTERED WARN_ON. v3: - Commit log improvement. [Uma] - Added a comment before scheduling prop_work. [Uma] Fixes: |

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

mm: don't put pinned pages into the swap cache
So technically there is nothing wrong with adding a pinned page to the
swap cache, but the pinning obviously means that the page can't actually
be free'd right now anyway, so it's a bit pointless.
However, the real problem is not with it being a bit pointless: the real
issue is that after we've added it to the swap cache, we'll try to unmap
the page. That will succeed, because the code in mm/rmap.c doesn't know
or care about pinned pages.
Even the unmapping isn't fatal per se, since the page will stay around
in memory due to the pinning, and we do hold the connection to it using
the swap cache. But when we then touch it next and take a page fault,
the logic in do_swap_page() will map it back into the process as a
possibly read-only page, and we'll then break the page association on
the next COW fault.
Honestly, this issue could have been fixed in any of those other places:
(a) we could refuse to unmap a pinned page (which makes conceptual
sense), or (b) we could make sure to re-map a pinned page writably in
do_swap_page(), or (c) we could just make do_wp_page() not COW the
pinned page (which was what we historically did before that "mm:
do_wp_page() simplification" commit).
But while all of them are equally valid models for breaking this chain,
not putting pinned pages into the swap cache in the first place is the
simplest one by far.
It's also the safest one: the reason why do_wp_page() was changed in the
first place was that getting the "can I re-use this page" wrong is so
fraught with errors. If you do it wrong, you end up with an incorrectly
shared page.
As a result, using "page_maybe_dma_pinned()" in either do_wp_page() or
do_swap_page() would be a serious bug since it is only a (very good)
heuristic. Re-using the page requires a hard black-and-white rule with
no room for ambiguity.
In contrast, saying "this page is very likely dma pinned, so let's not
add it to the swap cache and try to unmap it" is an obviously safe thing
to do, and if the heuristic might very rarely be a false positive, no
harm is done.

RISC-V Fixes for 5.11-rc4
There are a few more fixes than a normal rc4, largely due to the bubble introduced by the holiday break: * A fix to return -ENOSYS for syscall number -1, which previously returned an uninitialized value. * A fix to time_init() to ensure of_clk_init() has been called, without which clock drivers may not be initialized. * A fix to the sifive,uart0 driver to properly display the baud rate. A fix to initialize MPIE that allows interrupts to be processed during system calls. * A fix to avoid erronously begin tracing IRQs when interrupts are disabled, which at least triggers suprious lockdep failures. * A workaround for a warning related to calling smp_processor_id() while preemptible. The warning itself is suprious on currently availiable systems. * A fix to properly include the generic time VDSO calls. A fix to our kasan address mapping. A fix to the HiFive Unleashed device tree, which allows the Ethernet PHY to be properly initialized by Linux (as opposed to relying on the bootloader). * A defconfig update to include SiFive's GPIO driver, which is present on the HiFive Unleashed and necessary to initialize the PHY. * A fix to avoid allocating memory while initializing reserved memory. * A fix to avoid allocating the last 4K of memory, as pointers there alias with syscall errors.

A fix to initialize MPIE that allows interrupts to be processed during system calls. - avoid erronously begin tracing IRQs when interrupts are disabled, which at least triggers suprious lockdep failures. - workaround for a warning related to calling smp_processor_id() while preemptible. The warning itself is suprious on currently availiable systems. - properly include the generic time VDSO calls. A fix to our kasan address mapping.
