git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Alexander Gordeev:
- Rework copy_oldmem_page() callback to take an iov_iter.
This includes a few prerequisite updates and fixes to the oldmem
reading code.
- Rework cpufeature implementation to allow for various CPU feature
indications, which is not only limited to hardware capabilities, but
also allows CPU facilities.
- Use the cpufeature rework to autoload Ultravisor module when CPU
facility 158 is available.
- Add ELF note type for encrypted CPU state of a protected virtual CPU.
The zgetdump tool from s390-tools package will decrypt the CPU state
using a Customer Communication Key and overwrite respective notes to
make the data accessible for crash and other debugging tools.
- Use vzalloc() instead of vmalloc() + memset() in ChaCha20 crypto
test.
- Fix incorrect recovery of kretprobe modified return address in
stacktrace.
- Switch the NMI handler to use generic irqentry_nmi_enter() and
irqentry_nmi_exit() helper functions.
- Rework the cryptographic Adjunct Processors (AP) pass-through design
to support dynamic changes to the AP matrix of a running guest as
well as to implement more of the AP architecture.
- Minor boot code cleanups.
- Grammar and typo fixes to hmcdrv and tape drivers.

This reverts commit 4bf7fda4dce22214c70c49960b1b6438e6260b67.
It turns out that it was hopelessly naive to think that this would work,
considering that we've always done this. The first machine I actually
tested this on broke at bootup, getting to
Reached target cryptsetup.target - Local Encrypted Volumes.
and then hanging. It's unclear what actually fails, since there's a lot
else going on around that time (eg amdgpu probing also happens around
that same time, but it could be some other random init thing that didn't
complete earlier and just caused the boot to hang at that point).
The expectations that we should default to some unsafe and untested mode
seems entirely unfounded, and the belief that this wouldn't affect
modern systems is clearly entirely false. The machine in question is
about two years old, so it's not exactly shiny, but it's also not some
dusty old museum piece PDP-11 in a closet.

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull more device mapper updates from Mike Snitzer:
- Add flags argument to dm_bufio_client_create and introduce
DM_BUFIO_CLIENT_NO_SLEEP flag to have dm-bufio use spinlock rather
than mutex for its locking.
- Add optional "try_verify_in_tasklet" feature to DM verity target.
This feature gives users the option to improve IO latency by using a
tasklet to verify, using hashes in bufio's cache, rather than wait to
schedule a work item via workqueue. But if there is a bufio cache
miss, or an error, then the tasklet will fallback to using workqueue.
- Incremental changes to both dm-bufio and the DM verity target to use
jump_label to minimize cost of branching associated with the niche
"try_verify_in_tasklet" feature. DM-bufio in particular is used by
quite a few other DM targets so it doesn't make sense to incur
additional bufio cost in those targets purely for the benefit of this
niche verity feature if the feature isn't ever used.
- Optimize verity_verify_io, which is used by both workqueue and
tasklet based verification, if FEC is not configured or tasklet based
verification isn't used.
- Remove DM verity target's verify_wq's use of the WQ_CPU_INTENSIVE
flag since it uses WQ_UNBOUND. Also, use the WQ_HIGHPRI flag if
"try_verify_in_tasklet" is specified.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
- The most intrusive patch is small and changes the default allocation
policy for DMA addresses.
Before the change the allocator tried its best to find an address in
the first 4GB. But that lead to performance problems when that space
gets exhaused, and since most devices are capable of 64-bit DMA these
days, we changed it to search in the full DMA-mask range from the
beginning.
This change has the potential to uncover bugs elsewhere, in the
kernel or the hardware. There is a Kconfig option and a command line
option to restore the old behavior, but none of them is enabled by
default.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"As the diffstat shows, we've had lots of developments in a wide range
at this time; the majority of changes are about ASoC, including
subsystem-wide cleanups, continued SOF / Intel updates and a bunch of
new drivers (as usual), while there have been some significant (but
almost invisible) improvements in ALSA core side, too.
Below are some highlights:
Core:
- Faster lookups of control elements with Xarray; normal user won't
notice, but on the devices with tons of control elements, it can be
visibly faster
- Support for input validation for controls; this will harden for
badly written drivers in general with a slight overhead
- Deferred async signal handling for working around the potential
deadlocks
- Cleanup / refactoring raw MIDI locking code
ASoC:
- Restructing of the set_fmt() callbacks for making things clearer in
situations like CODEC to CODEC links
- Clean up and modernizing the DAI naming scheme setups
- Merge of more of the Intel AVS driver stack, including some board
integrations
- New version 4 mechanism for communication with SOF DSPs
- Suppoort for dynamically selecting the PLL to use at runtime on
i.MX platforms
- Improvements for CODEC to CODEC support in the generic cards
- Support for AMD Jadeite and various machines, AMD RPL, Intel
MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra

Pull perf tools updates from Arnaldo Carvalho de Melo:
- Introduce 'perf lock contention' subtool, using new lock contention
tracepoints and using BPF for in kernel aggregation and then
userspace processing using the perf tooling infrastructure for
resolving symbols, target specification, etc.
Since the new lock contention tracepoints don't provide lock names,
get up to 8 stack traces and display the first non-lock function
symbol name as a caller:
$ perf lock report -F acquired,contended,avg_wait,wait_total
Name acquired contended avg wait total wait
update_blocked_a... 40 40 3.61 us 144.45 us

Supports the usual 'perf record' + 'perf report' workflow as well as
a BCC/bpftrace like mode where you start the tool and then press
control+C to get results:

Fixes the following warnings observed when building
CONFIG_IPV6_SEG6_LWTUNNEL=y with clang:
net/ipv6/seg6_local.o: warning: objtool: seg6_local_fill_encap() falls
through to next function seg6_local_get_encap_size()
net/ipv6/seg6_local.o: warning: objtool: seg6_local_cmp_encap() falls
through to next function input_action_end()
LLVM can fully unroll loops in seg6_local_get_encap_size() and
seg6_local_cmp_encap(). One issue in those loops is that the induction
variable is initialized to 0. The loop iterates over members of
seg6_action_params, a global array of struct seg6_action_param calling
their put() function pointer members. seg6_action_param uses an array
initializer to initialize SEG6_LOCAL_SRH and later elements, which is
the third enumeration of an anonymous union.
The guard `if (attrs & SEG6_F_ATTR(i))` may prevent this from being
called at runtime, but it would still be UB for
`seg6_action_params[0]->put` to be called; the unrolled loop will make
the initial iterations unreachable, which LLVM will later rotate to
fallthrough to the next function.
Make this more obvious that this cannot happen to the compiler by
initializing the loop induction variable to the minimum valid index that
seg6_action_params is initialized to.

rose /proc code does not serialize timer accesses.
Initial report by Bernard F6BVP Pidoux exhibits overflow amounting
to 116 ticks on its HZ=250 system.
Full timer access serialization would imho be overkill as rose /proc
does not enforce consistency between displayed ROSE_STATE_XYZ and
timer values during changes of state.
The patch may also fix similar behavior in ax25 /proc, ax25 ioctl
and netrom /proc as they all exhibit the same timer serialization
policy. This point has not been reported though.
The sole remaining use of ax25_display_timer - ax25 rtt valuation -
may also perform marginally better but I have not analyzed it too
deeply.

For packets scheduled to RPM and LBK, NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
selects the TL3 or TL2 scheduling level as the one used for link/channel
selection and backpressure. For each scheduling queue at the selected
level: Setting NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG[ENA] = 1 allows
the TL3/TL2 queue to schedule packets to a specified RPM or LBK link
and channel.
There is an issue in the code where NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
is set to TL3 where as the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG is
configured for TL2 queue in some cases. As a result packets will not
transmit on that link/channel. This patch fixes the issue by configuring
the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG register depending on the
NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL] value.

Octeontx2 AF driver fixes for NPC
This patchset includes AF driver fixes wrt packet parser NPC.
Following are the changes:
Patch 1: The parser nibble configuration must be same for
TX and RX interfaces and if not fix up is applied. This fixup was
applied only for default profile currently and it has been fixed
to apply for all profiles.
Patch 2: Firmware image may not be present all times in the kernel image
and default profile is used mostly hence suppress the warning.
Patch 3: This patch fixes a corner case where NIXLF is detached but
without freeing its mcam entries which results in resource leak.
Patch 4: SMAC is overlapped with DMAC mistakenly while installing
rules based on SMAC. This patch fixes that.

cow fork
On a higly fragmented filesystem a Direct IO write can fail with -ENOSPC error
even though the filesystem has sufficient number of free blocks.
This occurs if the file offset range on which the write operation is being
performed has a delalloc extent in the cow fork and this delalloc extent
begins much before the Direct IO range.
In such a scenario, xfs_reflink_allocate_cow() invokes xfs_bmapi_write() to
allocate the blocks mapped by the delalloc extent. The extent thus allocated
may not cover the beginning of file offset range on which the Direct IO write
was issued. Hence xfs_reflink_allocate_cow() ends up returning -ENOSPC.
The following script reliably recreates the bug described above.

I /think/ this can happen if xfs_qm_flush_one is racing with
xfs_qm_dquot_isolate (i.e. dquot reclaim) when the second function has
taken the dquot flush lock but xfs_qm_dqflush hasn't yet locked the
dquot buffer, let alone queued it to the delwri list. In this case,
flush_one will fail to get the dquot flush lock, but it can lock the
incore buffer, but xfs_buf_delwri_pushbuf will then trip over this
ASSERT, which checks that the buffer isn't on a delwri list. The hang
results because the _delwri_submit_buffers ignores non DELWRI_Q buffers,
which means that xfs_buf_iowait waits forever for an IO that has not yet
been scheduled.
AFAICT, a reasonable solution here is to detect a dquot buffer that is
not on a DELWRI list, drop it, and return -EAGAIN to try the flush
again. It's not /that/ big of a deal if quotacheck writes the dquot
buffer repeatedly before we even set QUOTA_CHKD.

If a blkdev_issue_flush fails, fsync needs to report that to upper
levels. Modify xfs_file_fsync to capture the errors, while trying to
flush as much data and log updates to disk as possible.
If log writes cannot flush the data device, we need to shut down the log
immediately because we've violated a log invariant. Modify this code to
check the return value of blkdev_issue_flush as well.
This behavior seems to go back to about 2.6.15 or so, which makes this
fixes tag a bit misleading.

Vishal notes that when attempting to define a second pmem region on a
device the DPA allocation fails with a message of the form:
decoder11.1: failed to reserve skipped space
Recall that the skip setting is used when there is a pmem allocation in
the presence of free ram DPA space. The first pmem allocation skips over
the free ram and subsequent pmem allocations do not require a skip. The
bug is that a skip is still attempted and the DPA reservation code
flags the double skip allocation conflict.

The endpoint decode granularity must be <= the window granularity
otherwise capacity in the endpoints is lost in the decode. Consider an
attempt to have a region granularity of 512 with 4 devices within a
window that maps 2 host bridges at a granularity of 256 bytes:
HPA DPA Offset HB Port EP
0x0 0x0 0 0 0
0x100 0x0 1 0 2
0x200 0x100 0 0 0
0x300 0x100 1 0 2
0x400 0x200 0 1 1
0x500 0x200 1 1 3
0x600 0x300 0 1 1
0x700 0x300 1 1 3
0x800 0x400 0 0 0
0x900 0x400 1 0 2
0xA00 0x500 0 0 0
0xB00 0x500 1 0 2
Notice how endpoint0 maps HPA 0x0 and 0x200 correctly, but then at HPA
0x800 it results in DPA 0x200-0x400 on being skipped.
Fix this by restricing the region granularity to be equal to the window
granularity resulting in the following for a x4 region under a x2 window
at a granularity of 256.
HPA DPA Offset HB Port EP
0x0 0x0 0 0 0
0x100 0x0 1 0 2
0x200 0x0 0 1 1
0x300 0x0 1 1 3
0x400 0x100 0 0 0
0x500 0x100 1 0 2
0x600 0x100 0 1 1
0x700 0x100 1 1 3
Not that it ever made practical sense to support region granularity >
window granularity. The window rotates host bridges causing endpoints to
never see a consecutive stream of requests at the desired granularity
without breaks to issue cycles to the other host bridge.

In cases where the decode fans out as it traverses downstream, the
interleave granularity needs to increment to identify the port selector
bits out of the remaining address bits. For example, recall that with an
x2 parent port intereleave (IW == 1), the downstream decode for children
of those ports will either see address bit IG+8 always set, or address
bit IG+8 always clear. So if the child port needs to select a downstream
port it can only use address bits starting at IG+9 (where IG and IW are
the CXL encoded values for interleave granularity (ilog2(ig) - 8) and
ways (ilog2(iw))).
When the parent port interleave is x1 no such masking occurs and the
child port can maintain the granularity that was routed to the parent
port.

A recent bug fix added the setup of the endpoint decoder interleave
geometry settings to cxl_region_attach(). Move the HPA setup there as
well to keep all endpoint decoder parameter setting in a central
location.
For symmetry, move endpoint HPA teardown to cxl_region_detach(), and for
switches move HPA setup / teardown to cxl_port_{setup,reset}_targets().
