cxl for v6.3
- CXL RAM region enumeration: instantiate 'struct cxl_region' objects
for platform firmware created memory regions
- CXL RAM region provisioning: complement the existing PMEM region
creation support with RAM region support
- "Soft Reservation" policy change: Online (memory hot-add)
soft-reserved memory (EFI_MEMORY_SP) by default, but still allow for
setting aside such memory for dedicated access via device-dax.
- CXL Events and Interrupts: Takeover CXL event handling from
platform-firmware (ACPI calls this CXL Memory Error Reporting) and
export CXL Events via Linux Trace Events.
- Convey CXL _OSC results to drivers: Similar to PCI, let the CXL
subsystem interrogate the result of CXL _OSC negotiation.
- Emulate CXL DVSEC Range Registers as "decoders": Allow for
first-generation devices that pre-date the definition of the CXL HDM
Decoder Capability to translate the CXL DVSEC Range Registers into
'struct cxl_decoder' objects.
- Set timestamp: Per spec, set the device timestamp in case of hotplug,
or if platform-firwmare failed to set it.
- General fixups: linux-next build issues, non-urgent fixes for
pre-production hardware, unit test fixes, spelling and debug message
improvements.

Merge tag 'cxl-for-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull Compute Express Link (CXL) updates from Dan Williams:
"To date Linux has been dependent on platform-firmware to map CXL RAM
regions and handle events / errors from devices. With this update we
can now parse / update the CXL memory layout, and report events /
errors from devices. This is a precursor for the CXL subsystem to
handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that
for DDR-attached-DRAM is handled by the EDAC driver where it maps
system physical address events to a field-replaceable-unit (FRU /
endpoint device). In general, CXL has the potential to standardize
what has historically been a pile of memory-controller-specific error
handling logic.
Another change of note is the default policy for handling RAM-backed
device-dax instances. Previously the default access mode was "device",
mmap(2) a device special file to access memory. The new default is
"kmem" where the address range is assigned to the core-mm via
add_memory_driver_managed(). This saves typical users from wondering
why their platform memory is not visible via free(1) and stuck behind
a device-file. At the same time it allows expert users to deploy
policy to, for example, get dedicated access to high performance
memory, or hide low performance memory from general purpose kernel
allocations. This affects not only CXL, but also systems with
high-bandwidth-memory that platform-firmware tags with the
EFI_MEMORY_SP (special purpose) designation.
Summary:
- CXL RAM region enumeration: instantiate 'struct cxl_region' objects
for platform firmware created memory regions
- CXL RAM region provisioning: complement the existing PMEM region
creation support with RAM region support
- "Soft Reservation" policy change: Online (memory hot-add)
soft-reserved memory (EFI_MEMORY_SP) by default, but still allow
for setting aside such memory for dedicated access via device-dax.
- CXL Events and Interrupts: Takeover CXL event handling from

IOMMU Updates for Linux v6.3:
Including:
- Consolidate iommu_map/unmap functions. There have been
blocking and atomic variants so far, but that was problematic
as this approach does not scale with required new variants
which just differ in the GFP flags used.
So Jason consolidated this back into single functions that
take a GFP parameter. This has the potential to cause
conflicts with other trees, as they introduce new call-sites
for the changed functions. I offered them to pull in the
branch containing these changes and resolve it, but I am not
sure everyone did that. The conflicts this caused with
upstream up to v6.2-rc8 are resolved in the final merge
commit.
- Retire the detach_dev() call-back in iommu_ops
- Arm SMMU updates from Will:
- Device-tree binding updates:
* Cater for three power domains on SM6375
* Document existing compatible strings for Qualcomm SoCs
* Tighten up clocks description for platform-specific compatible strings
- Enable Qualcomm workarounds for some additional platforms that need them
- Intel VT-d updates from Lu Baolu:
- Add Intel IOMMU performance monitoring support
- Set No Execute Enable bit in PASID table entry
- Two performance optimizations
- Fix PASID directory pointer coherency
- Fix missed rollbacks in error path
- Cleanups
- Apple t8110 DART support
- Exynos IOMMU:
- Implement better fault handling
- Error handling fixes
- Renesas IPMMU:
- Add device tree bindings for r8a779g0
- AMD IOMMU:
- Various fixes for handling on SNP-enabled systems and
handling of faults with unknown request-ids

NFSD 6.3 Release Notes
Two significant security enhancements are part of this release:
* NFSD's RPC header encoding and decoding, including RPCSEC GSS
and gssproxy header parsing, has been overhauled to make it
more memory-safe.
* Support for Kerberos AES-SHA2-based encryption types has been
added for both the NFS client and server. This provides a clean
path for deprecating and removing insecure encryption types
based on DES and SHA-1. AES-SHA2 is also FIPS-140 compliant, so
that NFS with Kerberos may now be used on systems with fips
enabled.
In addition to these, NFSD is now able to handle crossing into an
auto-mounted mount point on an exported NFS mount. A number of
fixes have been made to NFSD's server-side copy implementation.
RPC metrics have been converted to per-CPU variables. This helps
reduce unnecessary cross-CPU and cross-node memory bus traffic,
and significantly reduces noise when KCSAN is enabled.

Networking changes for 6.3.
Core
----
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used
to describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols
---------
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP
path manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF
---
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key
to better support decap on GRE tunnel devices not operating
in collect metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk
and bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols
by livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter
---------
- Remove the CLUSTERIP target. It has been marked as obsolete
for years, and we still have WARN splats wrt. races of
the out-of-band /proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to
the existing 'delete' commands, but do not return an error if
the referenced object (set, chain, rule...) did not exist.
Driver API
----------
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into multiple
files, drop some of the unnecessarily granular locks and factor out
common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless Extensions
for Wi-Fi 7 devices at all. Everyone should switch to using nl80211
interface instead.
- Improve the CAN bit timing configuration. Use extack to return error
messages directly to user space, update the SJW handling, including
the definition of a new default value that will benefit CAN-FD
controllers, by increasing their oscillator tolerance.

- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on
boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols:
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF:
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols by
livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter:
- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.
Driver API:
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.
- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.

Pull btrfs updates from David Sterba:
"The usual mix of performance improvements and new features.
The core change is reworking how checksums are processed, with
followup cleanups and simplifications. There are two minor changes in
block layer and iomap code.
Features:
- block group allocation class heuristics:
- pack files by size (up to 128k, up to 8M, more) to avoid
fragmentation in block groups, assuming that file size and life
time is correlated, in particular this may help during balance
- with tracepoints and extensible in the future
Performance:
- send: cache directory utimes and only emit the command when
necessary
- speedup up to 10x
- smaller final stream produced (no redundant utimes commands
issued)
- compatibility not affected
- fiemap: skip backref checks for shared leaves
- speedup 3x on sample filesystem with all leaves shared (e.g. on
snapshots)
- micro optimized b-tree key lookup, speedup in metadata operations
(sample benchmark: fs_mark +10% of files/sec)
Core changes:
- change where checksumming is done in the io path:
- checksum and read repair does verification at lower layer
- cascaded cleanups and simplifications
- raid56 refactoring and cleanups
Fixes:
- sysfs: make sure that a run-time change of a feature is correctly
tracked by the feature files
- scrub: better reporting of tree block errors
Other:
- locally enable -Wmaybe-uninitialized after fixing all warnings
- misc cleanups, spelling fixes
Other code:
- block: export bio_split_rw
- iomap: remove IOMAP_F_ZONE_APPEND"

rxrpc: Fix overproduction of wakeups to recvmsg()
Fix three cases of overproduction of wakeups:
(1) rxrpc_input_split_jumbo() conditionally notifies the app that there's
data for recvmsg() to collect if it queues some data - and then its
only caller, rxrpc_input_data(), goes and wakes up recvmsg() anyway.
Fix the rxrpc_input_data() to only do the wakeup in failure cases.
(2) If a DATA packet is received for a call by the I/O thread whilst
recvmsg() is busy draining the call's rx queue in the app thread, the
call will left on the recvmsg() queue for recvmsg() to pick up, even
though there isn't any data on it.
This can cause an unexpected recvmsg() with a 0 return and no MSG_EOR
set after the reply has been posted to a service call.
Fix this by discarding pending calls from the recvmsg() queue that
don't need servicing yet.
(3) Not-yet-completed calls get requeued after having data read from them,
even if they have no data to read.
Fix this by only requeuing them if they have data waiting on them; if
they don't, the I/O thread will requeue them when data arrives or they
fail.

The aim of this patch is to reduce the fragmentation of block groups under certain unhappy workloads. It is particularly effective when the size of extents correlates with their lifetime, which is something we have observed causing fragmentation in the fleet at Meta. This patch categorizes extents into size classes: - x < 128KiB: "small" - 128KiB < x < 8MiB: "medium" - x > 8MiB: "large" and as much as possible reduces allocations of extents into block groups that don't match the size class. This takes advantage of any (possible) correlation between size and lifetime and also leaves behind predictable re-usable gaps when extents are freed; small writes don't gum up bigger holes. Size classes are implemented in the following way: - Mark each new block group with a size class of the first allocation that goes into it. - Add two new passes to ffe: "unset size class" and "wrong size class". First, try only matching block groups, then try unset ones, then allow allocation of new ones, and finally allow mismatched block groups. - Filtering is done just by skipping inappropriate ones, there is no special size class indexing. Other solutions I considered were: - A best fit allocator with an rb-tree. This worked well, as small writes didn't leak big holes from large freed extents, but led to regressions in ffe and write performance due to lock contention on the rb-tree with every allocation possibly updating it in parallel. Perhaps something clever could be done to do the updates in the background while being "right enough". - A fixed size "working set". This prevents freeing an extent drastically changing where writes currently land, and seems like a good option too. Doesn't take advantage of size in any way. - The same size class idea, but implemented with xarray marks. This turned out to be slower than looping the linked list and skipping wrong block groups, and is also less flexible since we must have only 3 size classes (max #marks). With the current approach we can have as many as we like. Performance testing was done via: https://github.com/josefbacik/fsperf Of particular relevance are the new fragmentation specific tests. A brief summary of the testing results: - Neutral results on existing tests. There are some minor regressions and improvements here and there, but nothing that truly stands out as notable. - Improvement on new tests where size class and extent lifetime are correlated. Fragmentation in these cases is completely eliminated and write performance is generally a little better. There is also significant improvement where extent sizes are just a bit larger than the size class boundaries. - Regression on one new tests: where the allocations are sized intentionally a hair under the borders of the size classes. Results are neutral on the test that intentionally attacks this new scheme by mixing extent size and lifetime. The full dump of the performance results can be found here: https://bur.io/fsperf/size-class-2022-11-15.txt (there are ANSI escape codes, so best to curl and view in terminal) Here is a snippet from the full results for a new test which mixes buffered writes appending to a long lived set of files and large short lived fallocates: bufferedappendvsfallocate results metric baseline current stdev diff ====================================================================================== avg_commit_ms 31.13 29.20 2.67 -6.22% bg_count 14 15.60 0 11.43% commits 11.10 12.20 0.32 9.91% elapsed 27.30 26.40 2.98 -3.30% end_state_mount_ns 11122551.90 10635118.90 851143.04 -4.38% end_state_umount_ns 1.36e+09 1.35e+09 12248056.65 -1.07% find_free_extent_calls 116244.30 114354.30 964.56 -1.63% find_free_extent_ns_max 599507.20 1047168.20 103337.08 74.67% find_free_extent_ns_mean 3607.19 3672.11 101.20 1.80% find_free_extent_ns_min 500 512 6.67 2.40% find_free_extent_ns_p50 2848 2876 37.65 0.98% find_free_extent_ns_p95 4916 5000 75.45 1.71% find_free_extent_ns_p99 20734.49 20920.48 1670.93 0.90% frag_pct_max 61.67 0 8.05 -100.00% frag_pct_mean 43.59 0 6.10 -100.00% frag_pct_min 25.91 0 16.60 -100.00% frag_pct_p50 42.53 0 7.25 -100.00% frag_pct_p95 61.67 0 8.05 -100.00% frag_pct_p99 61.67 0 8.05 -100.00% fragmented_bg_count 6.10 0 1.45 -100.00% max_commit_ms 49.80 46 5.37 -7.63% sys_cpu 2.59 2.62 0.29 1.39% write_bw_bytes 1.62e+08 1.68e+08 17975843.50 3.23% write_clat_ns_mean 57426.39 54475.95 2292.72 -5.14% write_clat_ns_p50 46950.40 42905.60 2101.35 -8.62% write_clat_ns_p99 148070.40 143769.60 2115.17 -2.90% write_io_kbytes 4194304 4194304 0 0.00% write_iops 2476.15 2556.10 274.29 3.23% write_lat_ns_max 2101667.60 2251129.50 370556.59 7.11% write_lat_ns_mean 59374.91 55682.00 2523.09 -6.22% write_lat_ns_min 17353.10 16250 1646.08 -6.36% There are some mixed improvements/regressions in most metrics along with an elimination of fragmentation in this workload.

btrfs: add more find_free_extent tracepoints
find_free_extent is a complicated function. It consists (at least) of: - a hint that jumps into the middle of a for loop macro - a middle loop trying every raid level - an outer loop ascending through ffe loop levels - complicated logic for skipping some of those ffe loop levels - multiple underlying in-bg allocators (zoned, cluster, no cluster) Which is all to say that more tracing is helpful for debugging its behavior. Add two new tracepoints: at the entrance to the block_groups loop (hit for every raid level and every ffe_ctl loop) and at the point we seriously consider a block_group for allocation. This way we can see the whole path through the algorithm, including hints, multiple loops, etc. Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com> Signed-off-by: Boris Burkov <boris@bur.io> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> |

net: bridge: Add a tracepoint for MDB overflows
The following patch will add two more maximum MDB allowances to the global one, mcast_hash_max, that exists today. In all these cases, attempts to add MDB entries above the configured maximums through netlink, fail noisily and obviously. Such visibility is missing when adding entries through the control plane traffic, by IGMP or MLD packets. To improve visibility in those cases, add a trace point that reports the violation, including the relevant netdevice (be it a slave or the bridge itself), and the MDB entry parameters: # perf record -e bridge:br_mdb_full & # [...] # perf script | cut -d: -f4- dev v2 af 2 src ::ffff:0.0.0.0 grp ::ffff:239.1.1.112/00:00:00:00:00:00 vid 0 dev v2 af 10 src :: grp ff0e::112/00:00:00:00:00:00 vid 0 dev v2 af 2 src ::ffff:0.0.0.0 grp ::ffff:239.1.1.112/00:00:00:00:00:00 vid 10 dev v2 af 10 src 2001:db8:1::1 grp ff0e::1/00:00:00:00:00:00 vid 10 dev v2 af 2 src ::ffff:192.0.2.1 grp ::ffff:239.1.1.1/00:00:00:00:00:00 vid 10 CC: Steven Rostedt <rostedt@goodmis.org> CC: linux-trace-kernel@vger.kernel.org Signed-off-by: Petr Machata <petrm@nvidia.com> Reviewed-by: Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: David S.

mm: discard __GFP_ATOMIC
__GFP_ATOMIC serves little purpose. Its main effect is to set ALLOC_HARDER which adds a few little boosts to increase the chance of an allocation succeeding, one of which is to lower the water-mark at which it will succeed. It is *always* paired with __GFP_HIGH which sets ALLOC_HIGH which also adjusts this watermark. It is probable that other users of __GFP_HIGH should benefit from the other little bonuses that __GFP_ATOMIC gets. __GFP_ATOMIC also gives a warning if used with __GFP_DIRECT_RECLAIM. There is little point to this. We already get a might_sleep() warning if __GFP_DIRECT_RECLAIM is set. __GFP_ATOMIC allows the "watermark_boost" to be side-stepped. It is probable that testing ALLOC_HARDER is a better fit here. __GFP_ATOMIC is used by tegra-smmu.c to check if the allocation might sleep. This should test __GFP_DIRECT_RECLAIM instead. This patch: - removes __GFP_ATOMIC - allows __GFP_HIGH allocations to ignore watermark boosting as well as GFP_ATOMIC requests. - makes other adjustments as suggested by the above. The net result is not change to GFP_ATOMIC allocations. Other allocations that use __GFP_HIGH will benefit from a few different extra privileges. This affects: xen, dm, md, ntfs3 the vermillion frame buffer hibernation ksm swap all of which likely produce more benefit than cost if these selected allocation are more likely to succeed quickly.

rxrpc: Simplify ACK handling
Now that general ACK transmission is done from the same thread as incoming DATA packet wrangling, there's no possibility that the SACK table will be being updated by the latter whilst the former is trying to copy it to an ACK. This means that we can safely rotate the SACK table whilst updating it without having to take a lock, rather than keeping all the bits inside it in fixed place and copying and then rotating it in the transmitter. Therefore, simplify SACK handing by keeping track of starting point in the ring and rotate slots down as we consume them.

sock: add tracepoint for send recv length
Add 2 tracepoints to monitor the tcp/udp traffic of per process and per cgroup. Regarding monitoring the tcp/udp traffic of each process, there are two existing solutions, the first one is https://www.atoptool.nl/netatop.php. The second is via kprobe/kretprobe. Netatop solution is implemented by registering the hook function at the hook point provided by the netfilter framework. These hook functions may be in the soft interrupt context and cannot directly obtain the pid. Some data structures are added to bind packets and processes. For example, struct taskinfobucket, struct taskinfo ... Every time the process sends and receives packets it needs multiple hashmaps,resulting in low performance and it has the problem fo inaccurate tcp/udp traffic statistics(for example: multiple threads share sockets). We can obtain the information with kretprobe, but as we know, kprobe gets the result by trappig in an exception, which loses performance compared to tracepoint. We compared the performance of tracepoints with the above two methods, and the results are as follows: ab -n 1000000 -c 1000 -r http://127.0.0.1/index.html without trace: Time per request: 39.660 [ms] (mean) Time per request: 0.040 [ms] (mean, across all concurrent requests) netatop: Time per request: 50.717 [ms] (mean) Time per request: 0.051 [ms] (mean, across all concurrent requests) kr: Time per request: 43.168 [ms] (mean) Time per request: 0.043 [ms] (mean, across all concurrent requests) tracepoint: Time per request: 41.004 [ms] (mean) Time per request: 0.041 [ms] (mean, across all concurrent requests It can be seen that tracepoint has better performance.

rxrpc: Move client call connection to the I/O thread
Move the connection setup of client calls to the I/O thread so that a whole
load of locking and barrierage can be eliminated. This necessitates the
app thread waiting for connection to complete before it can begin
encrypting data.
This also completes the fix for a race that exists between call connection
and call disconnection whereby the data transmission code adds the call to
the peer error distribution list after the call has been disconnected (say
by the rxrpc socket getting closed).
The fix is to complete the process of moving call connection, data
transmission and call disconnection into the I/O thread and thus forcibly
serialising them.
Note that the issue may predate the overhaul to an I/O thread model that
were included in the merge window for v6.2, but the timing is very much
changed by the change given below.

rxrpc: Tidy up abort generation infrastructure
Tidy up the abort generation infrastructure in the following ways:
(1) Create an enum and string mapping table to list the reasons an abort
might be generated in tracing.
(2) Replace the 3-char string with the values from (1) in the places that
use that to log the abort source. This gets rid of a memcpy() in the
tracepoint.
(3) Subsume the rxrpc_rx_eproto tracepoint with the rxrpc_abort tracepoint
and use values from (1) to indicate the trace reason.
(4) Always make a call to an abort function at the point of the abort
rather than stashing the values into variables and using goto to get
to a place where it reported. The C optimiser will collapse the calls
together as appropriate. The abort functions return a value that can
be returned directly if appropriate.
Note that this extends into afs also at the points where that generates an
abort. To aid with this, the afs sources need to #define
RXRPC_TRACE_ONLY_DEFINE_ENUMS before including the rxrpc tracing header
because they don't have access to the rxrpc internal structures that some
of the tracepoints make use of.

Clean up connection abort, using the connection state_lock to gate access to change that state, and use an rxrpc_call_completion value to indicate the difference between local and remote aborts as these can be pasted directly into the call state.

rxrpc: Implement a mechanism to send an event notification to a connection
Provide a means by which an event notification can be sent to a connection through such that the I/O thread can pick it up and handle it rather than doing it in a separate workqueue. This is then used to move the deferred final ACK of a call into the I/O thread rather than a separate work queue as part of the drive to do all transmission from the I/O thread.

rxrpc: Only disconnect calls in the I/O thread
Only perform call disconnection in the I/O thread to reduce the locking
requirement.
This is the first part of a fix for a race that exists between call
connection and call disconnection whereby the data transmission code adds
the call to the peer error distribution list after the call has been
disconnected (say by the rxrpc socket getting closed).
The fix is to complete the process of moving call connection, data
transmission and call disconnection into the I/O thread and thus forcibly
serialising them.
Note that the issue may predate the overhaul to an I/O thread model that
were included in the merge window for v6.2, but the timing is very much
changed by the change given below.
Fixes:

rxrpc: Only set/transmit aborts in the I/O thread
Only set the abort call completion state in the I/O thread and only transmit ABORT packets from there. rxrpc_abort_call() can then be made to actually send the packet. Further, ABORT packets should only be sent if the call has been exposed to the network (ie. at least one attempted DATA transmission has occurred for it).

rxrpc: Make the local endpoint hold a ref on a connected call
Make the local endpoint and it's I/O thread hold a reference on a connected call until that call is disconnected. Without this, we're reliant on either the AF_RXRPC socket to hold a ref (which is dropped when the call is released) or a queued work item to hold a ref (the work item is being replaced with the I/O thread).
