pressure with many open sockets, moving from a per socket cache to
a per-CPU one
- Replace rwlocks with RCU for better fairness in ping, raw sockets
and IP multicast router.
- Network-side support for IO uring zero-copy send.
- A few skb drop reason improvements, including codegen the source file
with string mapping instead of using macro magic.
- Rename reference tracking helpers to a more consistent
netdev_* schema.
- Adapt u64_stats_t type to address load/store tearing issues.
- Refine debug helper usage to reduce the log noise caused by bots.
BPF
---

Next week, there may be a second pull request to remove iomap_writepage from the other two filesystems (gfs2/zonefs) that use iomap for buffered IO. This follows in the same vein as the recent removal of writepage from XFS, since it hasn't been triggered in a few years; it does nothing during direct reclaim; and as far as the people who examined the patchset can tell, it's moving the codebase in the right direction. However, as it was a late addition to for-next, I'm holding off on that section for another week of testing to see if anyone can come up with a solid reason for holding off in the meantime.

Pull btrfs updates from David Sterba:
"This brings some long awaited changes, the send protocol bump,
otherwise lots of small improvements and fixes. The main core part is
reworking bio handling, cleaning up the submission and endio and
improving error handling.
There are some changes outside of btrfs adding helpers or updating
API, listed at the end of the changelog.
Features:
- sysfs:
- export chunk size, in debug mode add tunable for setting its size
- show zoned among features (was only in debug mode)
- show commit stats (number, last/max/total duration)
- send protocol updated to 2
- new commands:
- ability write larger data chunks than 64K
- send raw compressed extents (uses the encoded data ioctls),
ie. no decompression on send side, no compression needed on
receive side if supported
- send 'otime' (inode creation time) among other timestamps
- send file attributes (a.k.a file flags and xflags)
- this is first version bump, backward compatibility on send and
receive side is provided
- there are still some known and wanted commands that will be
implemented in the near future, another version bump will be
needed, however we want to minimize that to avoid causing
usability issues
- print checksum type and implementation at mount time
- don't print some messages at mount (mentioned as people asked about
it), we want to print messages namely for new features so let's
make some space for that
- big metadata - this has been supported for a long time and is
not a feature that's worth mentioning
- skinny metadata - same reason, set by default by mkfs
Performance improvements:
- reduced amount of reserved metadata for delayed items
- when inserted items can be batched into one leaf
- when deleting batched directory index items
- when deleting delayed items used for deletion
- overall improved count of files/sec, decreased subvolume lock
contention
- metadata item access bounds checker micro-optimized, with a few
percent of improved runtime for metadata-heavy operations
- increase direct io limit for read to 256 sectors, improved
throughput by 3x on sample workload
Notable fixes:
- raid56
- reduce parity writes, skip sectors of stripe when there are no
data updates
- restore reading from on-disk data instead of using stripe cache,
this reduces chances to damage correct data due to RMW cycle
- refuse to replay log with unknown incompat read-only feature bit
set
- zoned
- fix page locking when COW fails in the middle of allocation
- improved tracking of active zones, ZNS drives may limit the
number and there are ENOSPC errors due to that limit and not
actual lack of space
- adjust maximum extent size for zone append so it does not cause
late ENOSPC due to underreservation
- mirror reading error messages show the mirror number
- don't fallback to buffered IO for NOWAIT direct IO writes, we don't
have the NOWAIT semantics for buffered io yet
- send, fix sending link commands for existing file paths when there
are deleted and created hardlinks for same files
- repair all mirrors for profiles with more than 1 copy (raid1c34)
- fix repair of compressed extents, unify where error detection and
repair happen
Core changes:
- bio completion cleanups
- don't double defer compression bios
- simplify endio workqueues
- add more data to btrfs_bio to avoid allocation for read requests
- rework bio error handling so it's same what block layer does,
the submission works and errors are consumed in endio
- when asynchronous bio offload fails fall back to synchronous
checksum calculation to avoid errors under writeback or memory
pressure
- new trace points
- raid56 events
- ordered extent operations
- super block log_root_transid deprecated (never used)
- mixed_backref and big_metadata sysfs feature files removed, they've
been default for sufficiently long time, there are no known users
and mixed_backref could be confused with mixed_groups
Non-btrfs changes, API updates:
- minor highmem API update to cover const arguments
- switch all kmap/kmap_atomic to kmap_local
- remove redundant flush_dcache_page()
- address_space_operations::writepage callback removed
- add bdev_max_segments() helper"

EFI efivars sysfs interface removal
Remove the obsolete 'efivars' sysfs based interface to the EFI variable store, now that all users have moved to the efivarfs pseudo file system, which was created ~10 years ago to address some fundamental shortcomings in the sysfs based driver. Move the 'business logic' related to which EFI variables are important and may affect the boot flow from the efivars support layer into the efivarfs pseudo file system, so it is no longer exposed to other parts of the kernel. -----BEGIN PGP SIGNATURE----- iQGzBAABCgAdFiEE+9lifEBpyUIVN1cpw08iOZLZjyQFAmLhuYIACgkQw08iOZLZ jyRYYgwAwUvbFtBL+uOTB+jynOq1MkM1xrNSeEgzPyLhh7CXSa/e+48XqpQjCUxY 8HNqDvd4toiCeVKp25AO+FPrQBjT7NdyjnwGMP3DLkGCOSIrVqVJ/2OmbOY52Kzy z1qbF2+7ak1TUsGzMnJHVDB+baGnUlZ39DuR6IAWstM9tkH/QEnRJV+ejS4h7jdN XW42/M96mAYFfT4Q4gs1HJMPWLP22xoEbnb9SkOyFCB2tHDjrY94CqH8L7Ee1DgA 7sc2cAZ2mPlS8Rbs8NY8IA/LpN4tRu2EhbIxtmKMRgXA88aTKcsub9Tq9RXxzE/x BpkH77mGbSBSrntg0gskKCrYGyJaGS9EYnHVy5HPU8hJagK295NmO3c/trHTb90Z 1RZClYsIUbNXe06e9rdk8w8Ozn+7ABstxzLCvj2MThtTBnAbjU0kQ9VeD0xwMvOp EaF6D6tbEmHrZkGtKP2WEyOZm0tF2I3OP1U9LzjyTpvsIOINhqfVozlhTB6pU5YE kW9E59i+ =VVQ6 -----END PGP SIGNATURE----- Merge tag 'efi-efivars-removal-for-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi Pull efivars sysfs interface removal from Ard Biesheuvel: "Remove the obsolete 'efivars' sysfs based interface to the EFI variable store, now that all users have moved to the efivarfs pseudo file system, which was created ~10 years ago to address some fundamental shortcomings in the sysfs based driver.

tpm: eventlog: Fix section mismatch for DEBUG_SECTION_MISMATCH
If DEBUG_SECTION_MISMATCH enabled, __calc_tpm2_event_size() will not be
inlined, this cause section mismatch like this:
WARNING: modpost: vmlinux.o(.text.unlikely+0xe30c): Section mismatch in reference from the variable L0 to the function .init.text:early_ioremap()
The function L0() references
the function __init early_memremap().
This is often because L0 lacks a __init
annotation or the annotation of early_ioremap is wrong.
Fix it by using __always_inline instead of inline for the called-once
function __calc_tpm2_event_size().

KEYS: asymmetric: enforce SM2 signature use pkey algo
The signature verification of SM2 needs to add the Za value and
recalculate sig->digest, which requires the detection of the pkey_algo
in public_key_verify_signature(). As Eric Biggers said, the pkey_algo
field in sig is attacker-controlled and should be use pkey->pkey_algo
instead of sig->pkey_algo, and secondly, if sig->pkey_algo is NULL, it
will also cause signature verification failure.
The software_key_determine_akcipher() already forces the algorithms
are matched, so the SM3 algorithm is enforced in the SM2 signature,
although this has been checked, we still avoid using any algorithm
information in the signature as input.

sign-file: Fix confusing error messages
When an error occurs, use errx() instead of err() to display the error message, because openssl has its own error record. When an error occurs, errno will not be changed, while err() displays the errno error message. It will cause confusion. For example, when CMS_add1_signer() fails, the following message will appear: sign-file: CMS_add1_signer: Success errx() ignores errno and does not cause such issue.

tpm: Add tpm_tis_i2c backend for tpm_tis_core
Implement the TCG I2C Interface driver, as specified in the TCG PC
Client Platform TPM Profile (PTP) specification for TPM 2.0 v1.04
revision 14, section 8, I2C Interface Definition.
This driver supports Guard Times. That is, if required by the TPM, the
driver has to wait by a vendor-specific time after each I2C read/write.
The specific time is read from the TPM_I2C_INTERFACE_CAPABILITY register.
Unfortunately, the TCG specified almost but not quite compatible
register addresses. Therefore, the TIS register addresses need to be
mapped to I2C ones. The locality is stripped because for now, only
locality 0 is supported.
Add a sanity check to I2C reads of e.g. TPM_ACCESS and TPM_STS. This is
to detect communication errors and issues due to non-standard behaviour

tpm: Add tpm_tis_verify_crc to the tpm_tis_phy_ops protocol layer
Some TPMs, e.g. those implementing the I2C variant of TIS, can verify data transfers to/from the FIFO with a CRC. The CRC is calculated over the entirety of the FIFO register. Since the phy_ops layer is not aware when the core layer is done reading/writing the FIFO, CRC verification must be triggered from the core layer. To this end, add an optional phy_ops API call.

tpm: Add upgrade/reduced mode support for TPM1.2 modules
In case a TPM in failure mode is detected, the TPM should be accessible through a transparent communication channel for analysing purposes (e.g. TPM_GetTestResult) or a field upgrade. Since a TPM in failure mode has similar reduced functionality as in field upgrade mode, the flag TPM_CHIP_FLAG_FIRMWARE_UPGRADE is also valid. As described in TCG TPM Main Part1 Design Principles, Revision 116, chapter 9.2.1. the TPM also allows an update function in case a TPM is in failure mode. If the TPM in failure mode is detected, the function tpm1_auto_startup() sets TPM_CHIP_FLAG_FIRMWARE_UPGRADE flag, which is used later during driver initialization/deinitialization to disable functionality which makes no sense or will fail in the current TPM state. The following functionality is affected: * Do not register TPM as a hwrng * Do not get pcr allocation * Do not register sysfs entries which provide information impossible to obtain in limited mode Signed-off-by: Stefan Mahnke-Hartmann <stefan.mahnke-hartmann@infineon.com> Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org> |

Failing to do so may cause the stats attributes to be created by

Several core optimizations:
* threadgroup_rwsem write locking is skipped when configuring controllers in
empty subtrees. Combined with CLONE_INTO_CGROUP, this allows the common
static usage pattern to not grab threadgroup_rwsem at all (glibc still
doesn't seem ready for CLONE_INTO_CGROUP unfortunately).
* threadgroup_rwsem used to be put into non-percpu mode by default due to
latency concerns in specific use cases. There's no reason for everyone
else to pay for it. Make the behavior optional.
* psi no longer allocates memory when disabled.

cpuidle: Add cpu_idle_miss trace event
Add a trace event for cpuidle to track missed (too deep or too shallow) wakeups. After each wakeup, CPUIdle already computes whether the entered state was optimal, above or below the desired one and updates the relevant counters. This patch makes it possible to trace those events in addition to just reading the counters. The patterns of types and percentages of misses across different workloads appear to be very consistent. This makes the trace event very useful for comparing the relative correctness of different CPUIdle governors for different types of workloads, or for finding the optimal governor for a given device.

video: fbdev: i740fb: Check the argument of i740_calc_vclk()
Since the user can control the arguments of the ioctl() from the user
space, under special arguments that may result in a divide-by-zero bug.
If the user provides an improper 'pixclock' value that makes the argumet
of i740_calc_vclk() less than 'I740_RFREQ_FIX', it will cause a
divide-by-zero bug in:
drivers/video/fbdev/i740fb.c:353 p_best = min(15, ilog2(I740_MAX_VCO_FREQ / (freq / I740_RFREQ_FIX)));

x86/numa: Use cpumask_available instead of hardcoded NULL check
GCC-12 started triggering a new warning:
arch/x86/mm/numa.c: In function ‘cpumask_of_node’:
arch/x86/mm/numa.c:916:39: warning: the comparison will always evaluate as ‘false’ for the address of ‘node_to_cpumask_map’ will never be NULL [-Waddress]
916 | if (node_to_cpumask_map[node] == NULL) {
| ^~
node_to_cpumask_map is of type cpumask_var_t[].
When CONFIG_CPUMASK_OFFSTACK is set, cpumask_var_t is typedef'd to a
pointer for dynamic allocation, else to an array of one element. The
"wicked game" can be checked on line 700 of include/linux/cpumask.h.
The original code in debug_cpumask_set_cpu() and cpumask_of_node() were
probably written by the original authors with CONFIG_CPUMASK_OFFSTACK=y
(i.e. dynamic allocation) in mind, checking if the cpumask was available
via a direct NULL check.
When CONFIG_CPUMASK_OFFSTACK is not set, GCC gives the above warning
while compiling the kernel.
Fix that by using cpumask_available(), which does the NULL check when
CONFIG_CPUMASK_OFFSTACK is set, otherwise returns true. Use it wherever
such checks are made.
Conditional definitions of cpumask_available() can be found along with
the definition of cpumask_var_t. Check the cpumask.h reference mentioned
above.
