net: qrtr: correct types of trace event parameters
The arguments passed to the trace events are of type unsigned int,
however the signature of the events used __le32 parameters.
I may be missing the point here, but sparse flagged this and it
does seem incorrect to me.

tracing: Error if a trace event has an array for a __field()
A __field() in the TRACE_EVENT() macro is used to set up the fields of the trace event data. It is for single storage units (word, char, int, pointer, etc) and not for complex structures or arrays. Unfortunately, there's nothing preventing the build from accepting: __field(int, arr[5]); from building. It will turn into a array value. This use to work fine, as the offset and size use to be determined by the macro using the field name, but things have changed and the offset and size are now determined by the type. So the above would only be size 4, and the next field will be located 4 bytes from it (instead of 20). The proper way to declare static arrays is to use the __array() macro. Instead of __field(int, arr[5]) it should be __array(int, arr, 5). Add some macro tricks to the building of a trace event from the TRACE_EVENT() macro such that __field(int, arr[5]) will fail to build. A comment by the failure will explain why the build failed.

thermal/core: Relocate the traces definition in thermal directory
The traces are exported but only local to the thermal core code. On the other side, the traces take the thermal zone device structure as argument, thus they have to rely on the exported thermal.h header file. As we want to move the structure to the private thermal core header, first we have to relocate those traces to the same place as many drivers do.

kasan: remove PG_skip_kasan_poison flag
Code inspection reveals that PG_skip_kasan_poison is redundant with kasantag, because the former is intended to be set iff the latter is the match-all tag. It can also be observed that it's basically pointless to poison pages which have kasantag=0, because any pages with this tag would have been pointed to by pointers with match-all tags, so poisoning the pages would have little to no effect in terms of bug detection. Therefore, change the condition in should_skip_kasan_poison() to check kasantag instead, and remove PG_skip_kasan_poison and associated flags.

mm, printk: introduce new format %pGt for page_type
%pGp format is used to display 'flags' field of a struct page. However, some page flags (i.e. PG_buddy, see page-flags.h for more details) are stored in page_type field. To display human-readable output of page_type, introduce %pGt format. It is important to note the meaning of bits are different in page_type. if page_type is 0xffffffff, no flags are set. Setting PG_buddy (0x00000080) flag results in a page_type of 0xffffff7f. Clearing a bit actually means setting a flag. Bits in page_type are inverted when displaying type names. Only values for which page_type_has_type() returns true are considered as page_type, to avoid confusion with mapcount values. if it returns false, only raw values are displayed and not page type names.

ext4: Convert data=journal writeback to use ext4_writepages()
Add support for writeback of journalled data directly into ext4_writepages() instead of offloading it to write_cache_pages(). This actually significantly simplifies the code and reduces code duplication. For checkpointing of committed data we can use ext4_writepages() rightaway the same way as writeback of ordered data uses it on transaction commit. For journalling of dirty mapped pages, we need to add a special case to mpage_prepare_extent_to_map() to add all page buffers to the journal.

spi: Replace all spi->chip_select and spi->cs_gpiod references with function call
Supporting multi-cs in spi drivers would require the chip_select & cs_gpiod members of struct spi_device to be an array. But changing the type of these members to array would break the spi driver functionality. To make the transition smoother introduced four new APIs to get/set the spi->chip_select & spi->cs_gpiod and replaced all spi->chip_select and spi->cs_gpiod references with get or set API calls. While adding multi-cs support in further patches the chip_select & cs_gpiod members of the spi_device structure would be converted to arrays & the "idx" parameter of the APIs would be used as array index i.e., spi->chip_select[idx] & spi->cs_gpiod[idx] respectively.

Fix the nid_t field so that its size is correctly reported in the text format embedded in trace.dat files. As it stands, it is reported as being of size 4: field:nid_t nid[3]; offset:24; size:4; signed:0; Instead of 12: field:nid_t nid[3]; offset:24; size:12; signed:0; This also fixes the reported offset of subsequent fields so that they match with the actual struct layout.

fs: dlm: change dflags to use atomic bits
Currently manipulating lkb_dflags assumes to held the rsb lock assigned to the lkb. This is held by dlm message processing after certain time to lookup the right rsb from the received lkb message id. For user space locks flags, which is currently the only use case for lkb_dflags, flags are also being set during dlm character device handling without holding the rsb lock. To minimize the risk that bit operations are getting corrupted we switch to atomic bit operations. This patch will also introduce helpers to snapshot atomic bit values in an non atomic way. There might be still issues with the flag handling e.g. running in case of manipulating bit ops and snapshot them at the same time, but this patch minimize them and will start to use atomic bit operations.

fs: dlm: store lkb distributed flags into own value
This patch stores lkb distributed flags value in an separate value instead of sharing internal and distributed flags in lkb->lkb_flags value. This has the advantage to not mask/write back flag values in receive_flags() functionality. The dlm debug_fs does not provide the distributed flags anymore, those can be added in future.

fs: dlm: remove DLM_IFL_LOCAL_MS flag
The DLM_IFL_LOCAL_MS flag is an internal non shared flag but used in m_flags of dlm messages. It is not shared because it is only used for local messaging. Instead using DLM_IFL_LOCAL_MS in dlm messages we pass a parameter around to signal local messaging or not. This patch is adding the local parameter to signal local messaging.

fs: dlm: rename stub to local message flag
This patch renames DLM_IFL_STUB_MS to DLM_IFL_LOCAL_MS flag. The DLM_IFL_STUB_MS flag is somewhat misnamed, it means the dlm message is used for local message transfer only. It is used by recovery to resolve lock states if a node got fenced. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com> |

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.

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 - Cleanups and other small fixes - Various other smaller fixes and cleanups -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAmP0hDwACgkQK/BELZcB GuM43RAA0YieShO+X0h6TFGfbK0zVoPd91giZehWBv9rHK7pP4iY8UEtBLBWGx/t CId4t98mmKmC212zz8QxrwAEzyTIRY+2t1yrpG2aVkoTYk8inMb07TU37wganh3O T0QccXN+9b2BS4k8yro5f3uX0d/C1JQVcMowwr53VMb/e73huqP1VTbz06/CIWMH DUhVRCzmNhSvoUOT5n7g6+ZDH+pot8WPZbtHV7FowEsmPCRc7Fj8kXyI9FEwKwrZ hIV5Y+6Lej8nQScgbO8MfblJym3VrBoSoM4GY2w0L0rjQw6m+Xtea5rT0W39YVWy YpiscLTL8TIMPP9zK1dXVygTaABK4J2iWmheHPkpKXIhK0iuH3Dke0Do5p6DNITj 7J2YlaNEB480D5hvNBKsbbGHavgGPT8m529Sz0R7mSC7omRzqiG5Vsb46IXL+2bc 92ojjYNfXb6OCtagIr2LMBLZRL2JCODqF1dUmyZfA8GKOHLP5kZXoMM+sZbQ2aUL 1LOxRZVx+tlb9V4VaH1ZSs/6eM+HLDzjtHeu3PoWYf6mW4AEt4S/yl9SKAkGdBqt jCUErmYB1nU/eefqG1jhWRpQeJabcT3Oe30NZru1pfMoREThhjbAACw1JxWtoe1X ipGpV6lAP7tQUGuRk3/9O1lNqElJuNwC5lVTjS4FJ38vYQhQbao= =ZaZV -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu updates from Joerg Roedel: - Consolidate iommu_map/unmap functions.

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. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmPzgiYACgkQM2qzM29m f5dB2A//eqjpj+FgAN+UjygrwMC4ahAsPX3Sc3FG8/lTAiao3NFVFY2gxAiCPyVE CFk+tUyfL23oXvbyfIBe3LhxSBOf621xU6up2OzqAzJqh1Q9iUWB6as3I14to8ZU sWpxXo5ofwk1hzkbrvOAVkyfY0emwsr00iBeWMawkpBe8FZEQA31OYj3/xHr6bBI zEVlZPBZAZlp0DZ74tb+bBLs/EOnqKj+XLWcogCH13JB3sn2umF6cQNkYgsxvHGa TNQi4LEdzWZGme242LfBRiGGwm1xuVIjlAhYV/R1wIjaknE3QBzqfXc6lJx74WII HaqpRJGrKqdo7B+1gaXCl/AMS7YluED1CBrxuej0wBG7l2JEB7m2MFMQ4LTQjgsn nrr3P70DgbB4LuPCPyUS7dtsMmUXabIqP7niiCR4T1toH6lBmHAgEi4cFmkzg7Cd EoFzn888mtDpfx4fghcsRWS5oKXEzbPJfu5+IZOD63+UB+NGpi0Xo2s23sJPK8vz kqK/X63JYOUxWUvK0zkj/c/wW1cLqIaBwnSKbShou5/BL+cZVI+uJYrnEesgpoB2 5fh/cZv3hdcoOPO7OfcjCLQYy4J6RCWajptnk/hcS3lMvBTBrnq697iAqCVURDKU Xfmlf7XbBwje+sk4eHgqVGEqqVjrEmoqbmA2OS44WSS5LDvxXdI= =ZG/7 -----END PGP SIGNATURE----- Merge tag 'nfsd-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "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.

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.

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.

btrfs: introduce size class to block group allocator
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.

Such visibility is missing when adding entries through the control plane traffic, by IGMP or MLD packets.

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.

Arm SCMI updates for v6.3
The main addition is a unified userspace interface for SCMI irrespective of the underlying transport and along with some changed to refactor the SCMI stack probing sequence. 1. SCMI unified userspace interface This is to have a unified way of testing an SCMI platform firmware implementation for compliance, fuzzing etc., from the perspective of the non-secure OSPM irrespective of the underlying transport supporting SCMI. It is just for testing/development and not a feature intended fo use in production. Currently an SCMI Compliance Suite[1] can only work by injecting SCMI messages using the mailbox test driver only which makes it transport specific and can't be used with any other transport like virtio, smc/hvc, optee, etc. Also the shared memory can be transport specific and it is better to even abstract/hide those details while providing the userspace access. So in order to scale with any transport, we need a unified interface for the same. In order to achieve that, SCMI "raw mode support" is being added through debugfs which is more configurable as well. A userspace application can inject bare SCMI binary messages into the SCMI core stack; such messages will be routed by the SCMI regular kernel stack to the backend platform firmware using the configured transport transparently. This eliminates the to know about the specific underlying transport internals that will be taken care of by the SCMI core stack itself. Further no additional changes needed in the device tree like in the mailbox-test driver. [1] https://gitlab.arm.com/tests/scmi-tests 2. Refactoring of the SCMI stack probing sequence On some platforms, SCMI transport can be provide by OPTEE/TEE which introduces certain dependency in the probe ordering. In order to address the same, the SCMI bus is split into its own module which continues to be initialized at subsys_initcall, while the SCMI core stack, including its various transport backends (like optee, mailbox, virtio, smc), is now moved into a separate module at module_init level. This allows the other possibly dependent subsystems to register and/or access SCMI bus well before the core SCMI stack and its dependent transport backends. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmPKvdkACgkQAEG6vDF+ 4pgB0g//eU5S0aTgt8XlwDmdjeu+mNrj68QHKINq9CS7PmBs37So0IdLJ+CpqJlo VSmk2kI5oLWz/u3N92QQY9RXM4hvO95kiPKuyO8NsoPWrfjBZH3rKcgEpRquZjrt TdBUPd2aqoKhFqkUzxs5lNEZOV/R6mm0q+i9dD4RIRKP9Tjrlm3jYDSMFnW3/QMJ OR3Ub0e/4Lj3QyNUxrUqwpdjTiAqXimCW7LWZ2fwY5kPxcL4wedAfQS3zGa5m8Wk htqRTXmYtSVKAZ/oFUPDOHuZUNqn0ZdNI7guEPgzo90+pJs0yQUQf/wtc+X9quXZ /FUGaVSTzlvcl1MPJPTPQ9d7dJH8lR0+nxzovkBSoMX/tNByuVtBUpNiclu8seob CqbywRtASkd0g6dKHHEIylwj0FpRSYBLJEcE6jXhxfvXt+sCDZbDSUpWaGGZnNqO oj8FhEmRk/t/d+ZEkn6MlRgy5uiJSv4GstNQ5V/ZSz3vhp1u2Sl7y8xAcuVsqXyH Dok6iM9GoSdskCdSICk5iA2ESC5s+1IiDd2PnSwWz+yj9HbmWKwU0nKgRRWvDUZh jJYWAvcwuh3SQ/sN/FNTVsxQt/x5V3L/K7oe2o983l0Lq8k9WB0mEBAyRidxAlVj TpfXbe9CDqJtoF85Bslb7eS++iGADkVvmWAqjqUQddFQR++Dj2w= =yLSu -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmPQQ0QACgkQmmx57+YA GNlYsRAAr/qGRRSiOtTYZi0yPmSuGCYb4xORbJHS00gD3aRzrehtsf//av4WyeyM cGpeR/2OIa66/M7wIjKM7lHXBdzFxLgwAM9DkexVwY1i7w6ExDZFClX7UhlgmwiM LbsApqHYW/DhAnOBL7SXPQkDIcTifURvOZCOJ0NJg5HOn+DeRP5UPEE5Xbqt0+yc JUnKC2eqN15G/BWJCWtmfZVXwMKtWB8ScU2HJeoEjjH7d31XvWvw5z0upyhlEQvb lqhFgKftEY+boEfbz86AoZoBY8EWFdqB8RvcNOmReU8hyequjnrK/ykQq9EAAMmo LbxNkW72zN727ji3O7onX8zWjqYLKjV3FC/cuNah//USQa8nPvq4atXf+D7my0fC Rm9ZF3ztHQjTgMVlmm/uAU3c4BxEcwHMnppEoYvxa23ErSt+hp2aJvfDfseMAYFW 2iie4KAR03WeHnspYioa88PHj83SeT9AsHxf+PCdXkXgzl74HDVrt/8gpLQMmu4Q BTkwTF3QvEry5c6uF7yI/oOuQq06Y03miN5GEQKtqTIIpn3g/tJs0GJot0nUPZ0f xJJ+mlOcoc76zwaDARcGJO0yzX9qJt4I+/HS39BLvMt2EfbZ3IXlSsQu7esd5p2V 6xokmygD5rZY92CMd3SPpJ4xRBHUN6PIFb1GUyJmg9xoghDwjXs= =jvm3 -----END PGP SIGNATURE----- Merge tag 'scmi-updates-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.3 The main addition is a unified userspace interface for SCMI irrespective of the underlying transport and along with some changed to refactor the SCMI stack probing sequence. 1.

The result of the allocation attempt is not printed in trace_cma_alloc_finish, but it's important to do it so we can set filters to catch specific errors on allocation or to trigger some operations on specific errors. We have printed the result in log, but the log is conditional and could not be filtered by tracing events. It introduces little overhead to print this result. The result of allocation is named `errorno' in the trace.

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: Offload the completion of service conn security to the I/O thread
Offload the completion of the challenge/response cycle on a service connection to the I/O thread. After the RESPONSE packet has been successfully decrypted and verified by the work queue, offloading the changing of the call states to the I/O thread makes iteration over the conn's channel list simpler. Do this by marking the RESPONSE skbuff and putting it onto the receive queue for the I/O thread to collect. We put it on the front of the queue as we've already received the packet for it.

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.

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.

Only perform call disconnection in the I/O thread to reduce the locking

This is the first part of a fix for a race that exists between call

The fix is to complete the process of moving call connection, data

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.

cxl/pci: Move tracepoint definitions to drivers/cxl/core/
CXL is using tracepoints for reporting RAS capability register payloads for AER events, and has plans to use tracepoints for the output payload of Get Poison List and Get Event Records commands. For organization purposes it would be nice to keep those all under a single + local CXL trace system. This also organization also potentially helps in the future when CXL drivers expand beyond generic memory expanders, however that would also entail a move away from the expander-specific cxl_dev_state context, save that for later. Note that the powerpc-specific drivers/misc/cxl/ also defines a 'cxl' trace system, however, it is unlikely that a single platform will ever load both drivers simultaneously.

rxrpc: Fix a couple of potential use-after-frees
At the end of rxrpc_recvmsg(), if a call is found, the call is put and then
a trace line is emitted referencing that call in a couple of places - but
the call may have been deallocated by the time those traces happen.
Fix this by stashing the call debug_id in a variable and passing that to
the tracepoint rather than the call pointer.

rseq: Extend struct rseq with numa node id
Adding the NUMA node id to struct rseq is a straightforward thing to do, and a good way to figure out if anything in the user-space ecosystem prevents extending struct rseq. This NUMA node id field allows memory allocators such as tcmalloc to take advantage of fast access to the current NUMA node id to perform NUMA-aware memory allocation. It can also be useful for implementing fast-paths for NUMA-aware user-space mutexes. It also allows implementing getcpu(2) purely in user-space.

f2fs-for-6.2-rc1
In this round, we've added two features: 1) F2FS_IOC_START_ATOMIC_REPLACE and 2) per-block age-based extent cache. 1) is a variant of the previous atomic write feature which guarantees a per-file atomicity. It would be more efficient than AtomicFile implementation in Android framework. 2) implements another type of extent cache in memory which keeps the per-block age in a file, so that block allocator could split the hot and cold data blocks more accurately. Enhancement: - introduce F2FS_IOC_START_ATOMIC_REPLACE - refactor extent_cache to add a new per-block-age-based extent cache support - introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs - add proc entry to show discard_plist info - optimize iteration over sparse directories - add barrier mount option Bug fix - avoid victim selection from previous victim section - fix to enable compress for newly created file if extension matches - set zstd compress level correctly - initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot - correct i_size change for atomic writes - allow to read node block after shutdown - allow to set compression for inlined file - fix gc mode when gc_urgent_high_remaining is 1 - should put a page when checking the summary info Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and doc. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmOaTNUACgkQQBSofoJI UNIQnw//V7Q8DUHw5YNj04jutwXH2DNMLAmn/NJh5S6dIzy/LiywlSzVg53/0/FP 4K577urUkIhgilRO+yncUMSnSQk7BluQvGSx4ja2AV+dpDomjxM3GwIacGzSvr7D VfVf8Vig10UEFrrtEEKtv1VFlYHAmo8lLpubzrZHV8aZFLHHYO2fakQhPu8BYsaz eGCJwxjvTZcQUPkaeG9tWto3ChI3F6PzreiQ5TztHhLWSEgw/o0qijpsc+2SthaV my7uGjeBY8EGPeSYbeCxRtdx8g8Qu11K3ISuDj8zBybmjG3IWOGt1CVcrY6tZbal aL70CMtHkMqMn03VqbpCTqBtdWNMrrw5sYSL3qXIUdXlX/2yJBh9fLAeNxKNs5Nu 6veSb2WgYMHqIsClkAAcP0xJ8g6kodGoG60wVr4ek0Vdt4osaQqwq+bnffpwwxtQ F+7aRuinv+rdrHJ4CuFXAmHPKh2lBe2lTTWZEKg2RptTxZ5DhD2Qn6x1khPD2GFA mG2Aeiq6PVxxEeIO+w/VBCuAgpGTFV2N/ZIF8VfjFNdWiN5OGLWQNHC2KGj2G2uV +fA+B91txQWtjY9h72YJb2+aGIixcnLY24ni4mDgDItqtpCB4PW56W8cbnbv9Pl+ aXAWdADqJdDyllHoVB/JQ24gr2fATJGRIDeYDnw+vPP4f5ZT5vg= =f00t -----END PGP SIGNATURE----- Merge tag 'f2fs-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added two features: F2FS_IOC_START_ATOMIC_REPLACE and a per-block age-based extent cache.

A pile of clk driver updates with a small tracepoint patch to the clk core this
time around. The core framework is effectively unchanged, with the majority of the diff going to the Qualcomm clk driver directory because they added two 3k line files that are almost all clk data (Abel Vesa from Linaro tried to shrink the number of lines down, but it doesn't seem to be possible without sacrificing readability). The second big driver this time around is the Rockchip rk3588 clk and reset unit, at _only_ 2.5k lines. Ignoring the big clk drivers from the familiar SoC vendors, there's just a bunch of little clk driver updates and fixes throughout here. It's the usual set of clk data fixups to describe proper parents, or add frequencies to frequency tables, or plug memory leaks when function calls fail. Also, some drivers are converted to use modern clk_hw APIs, which is always nice to see. And data is deduplicated, leading to a smaller kernel Image. Overall this batch has a larger collection of cleanups than it typically does. Maybe that means there are less new SoCs right now that need supporting, and the focus has shifted to quality and reliability. I can dream.

tracing: Remove pointer (asterisk) and brackets from cpumask_t field
To differentiate between long arrays and cpumasks, the __cpumask() field
was created. Part of the TRACE_EVENT() macros test if the type is signed
or not by using the is_signed_type() macro. The __cpumask() field used the
__dynamic_array() helper but because cpumask_t is a structure, it could
not be used in the is_signed_type() macro as that would fail to build, so
instead it passed in the pointer to cpumask_t.
Unfortunately, that creates in the format file:
field:__data_loc cpumask_t *[] mask; offset:36; size:4; signed:0;
Which looks like an array of pointers to cpumask_t and not a cpumask_t
type, which is misleading to user space parsers.
Douglas Raillard pointed out that the "[]" are also misleading, as
cpumask_t is not an array.
Since cpumask() hasn't been created yet, and the parsers currently fail on
it (but will still produce the raw output), make it be:
field:__data_loc cpumask_t mask; offset:36; size:4; signed:0;
Which is the correct type of the field.
Then the parsers can be updated to handle this.

NFSD 6.2 Release Notes
This release introduces support for the CB_RECALL_ANY operation. NFSD can send this operation to request that clients return any delegations they choose. The server uses this operation to handle low memory scenarios or indicate to a client when that client has reached the maximum number of delegations the server supports. The NFSv4.2 READ_PLUS operation has been simplified temporarily whilst support for sparse files in local filesystems and the VFS is improved. Two major data structure fixes appear in this release: * The nfs4_file hash table is replaced with a resizable hash table to reduce the latency of NFSv4 OPEN operations. * Reference counting in the NFSD filecache has been hardened against races. In furtherance of removing support for NFSv2 in a subsequent kernel release, a new Kconfig option enables server-side support for NFSv2 to be left out of a kernel build. MAINTAINERS has been updated to indicate that changes to fs/exportfs should go through the NFSD tree. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmOXPE4ACgkQM2qzM29m f5faaRAAh7YT5V61afPbfgBybO5AbDzztpZSNjNjLZs78piSnFp6hP75yNtTviwQ 1o7St13/NkCmDaIdGUpr02U01zbM1BDOq2wGckImOJLNSgb7xHV5r4PqkRiFkh0t QYSnwG+wp8fDUJeCL/nAOAu9I9EQUqHzWchxiU/h8ln2hN3rXUlIRSeo17Wy7zkD cNIcoAjTi9fzY3dE6H4r+lZTdNCYH+AdzChmKrHdRZQwq0Xs3FWv4gAMTLbDuD4P B6NDHz0Umn6XnFsJGptwozkwaWeMQw4GyJj/3iUiO8JF209SaoYXMPjJAyG6tYYa fUrgv4UXGeXjigDbLBA5IYxfhX7GXjMQSaj3edhzyrl8P74q4/Cq/8fDUnAZ841m E+TGSCPIQD0QuIjdXxLv9KLY8JNThSfcAt6jr5GBXhPZQr8xpS0BqK/Onr68fgZC Lpull5xN68L4A1B7cf2GNPuMyvkBKxwSGXOehldh/BkvpVMjFwqd4/q5xWC+6CcQ tbOkjTbbSS71nzJwZip0NphaYCa3qQPzKT4SZzn/I4I9W5otbwYBx734Bw46gTDE ZPUXTuJ00VPgX07wbLRahg521Fwzr+8sk1WnVYq82PoaMh1l9FjzLNGouQWBdo3E UzIo/KUfQKmoZce6O723L6OI4ffdK5oMtfaTpe+SiUPpV1lUAcA= =jNlu -----END PGP SIGNATURE----- Merge tag 'nfsd-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "This release introduces support for the CB_RECALL_ANY operation.

f2fs: add block_age-based extent cache
This patch introduces a runtime hot/cold data separation method for f2fs, in order to improve the accuracy for data temperature classification, reduce the garbage collection overhead after long-term data updates. Enhanced hot/cold data separation can record data block update frequency as "age" of the extent per inode, and take use of the age info to indicate better temperature type for data block allocation: - It records total data blocks allocated since mount; - When file extent has been updated, it calculate the count of data blocks allocated since last update as the age of the extent; - Before the data block allocated, it searches for the age info and chooses the suitable segment for allocation. Test and result: - Prepare: create about 30000 files * 3% for cold files (with cold file extension like .apk, from 3M to 10M) * 50% for warm files (with random file extension like .FcDxq, from 1K to 4M) * 47% for hot files (with hot file extension like .db, from 1K to 256K) - create(5%)/random update(90%)/delete(5%) the files * total write amount is about 70G * fsync will be called for .db files, and buffered write will be used for other files The storage of test device is large enough(128G) so that it will not switch to SSR mode during the test. Benefit: dirty segment count increment reduce about 14% - before: Dirty +21110 - after: Dirty +18286 Signed-off-by: qixiaoyu1 <qixiaoyu1@xiaomi.com> Signed-off-by: xiongping1 <xiongping1@xiaomi.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

While it may seem backwards, the CXL update this time around includes some focus on CXL 1.x enabling where the work to date had been with CXL 2.0 (VH topologies) in mind. First generation CXL can mostly be supported via BIOS, similar to DDR, however it became clear there are use cases for OS native CXL error handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x hosts (Restricted CXL Host (RCH) topologies). So, this update brings RCH topologies into the Linux CXL device model. In support of the ongoing CXL 2.0+ enabling two new core kernel facilities are added. One is the ability for the kernel to flag collisions between userspace access to PCI configuration registers and kernel accesses. This is brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware mailbox over config-cycles. The other is a cpu_cache_invalidate_memregion() API that maps to wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest VMs and architectures that do not support it yet. The CXL paths that need it, dynamic memory region creation and security commands (erase / unlock), are disabled when it is not present. As for the CXL 2.0+ this cycle the subsystem gains support Persistent Memory Security commands, error handling in response to PCIe AER notifications, and support for the "XOR" host bridge interleave algorithm. Summary: - Add the cpu_cache_invalidate_memregion() API for cache flushing in response to physical memory reconfiguration, or memory-side data invalidation from operations like secure erase or memory-device unlock. - Add a facility for the kernel to warn about collisions between kernel and userspace access to PCI configuration registers - Add support for Restricted CXL Host (RCH) topologies (formerly CXL 1.1) - Add handling and reporting of CXL errors reported via the PCIe AER mechanism - Add support for CXL Persistent Memory Security commands - Add support for the "XOR" algorithm for CXL host bridge interleave - Rework / simplify CXL to NVDIMM interactions - Miscellaneous cleanups and fixes" * tag 'cxl-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (71 commits) cxl/region: Fix memdev reuse check cxl/pci: Remove endian confusion cxl/pci: Add some type-safety to the AER trace points cxl/security: Drop security command ioctl uapi cxl/mbox: Add variable output size validation for internal commands cxl/mbox: Enable cxl_mbox_send_cmd() users to validate output size cxl/security: Fix Get Security State output payload endian handling cxl: update names for interleave ways conversion macros cxl: update names for interleave granularity conversion macros cxl/acpi: Warn about an invalid CHBCR in an existing CHBS entry tools/testing/cxl: Require cache invalidation bypass cxl/acpi: Fail decoder add if CXIMS for HBIG is missing cxl/region: Fix spelling mistake "memergion" -> "memregion" cxl/regs: Fix sparse warning cxl/acpi: Set ACPI's CXL _OSC to indicate RCD mode support tools/testing/cxl: Add an RCH topology cxl/port: Add RCD endpoint port enumeration cxl/mem: Move devm_cxl_add_endpoint() from cxl_core to cxl_mem tools/testing/cxl: Add XOR Math support to cxl_test cxl/acpi: Support CXL XOR Interleave Math (CXIMS) ... |

ext4: disable fast-commit of encrypted dir operations
fast-commit of create, link, and unlink operations in encrypted
directories is completely broken because the unencrypted filenames are
being written to the fast-commit journal instead of the encrypted
filenames. These operations can't be replayed, as encryption keys
aren't present at journal replay time. It is also an information leak.
Until if/when we can get this working properly, make encrypted directory
operations ineligible for fast-commit.
Note that fast-commit operations on encrypted regular files continue to
be allowed, as they seem to work.

clk: Add trace events for rate requests
It is currently fairly difficult to follow what clk_rate_request are issued, and how they have been modified once done. Indeed, there's multiple paths that can be taken, some functions are recursive and will just forward the request to its parent, etc. Adding a lot of debug prints is just not very convenient, so let's add trace events for the clock requests, one before they are submitted and one after they are returned. That way we can simply toggle the tracing on without modifying the kernel code and without affecting performances or the kernel logs too much.

fscache: Fix oops due to race with cookie_lru and use_cookie
If a cookie expires from the LRU and the LRU_DISCARD flag is set, but
the state machine has not run yet, it's possible another thread can call
fscache_use_cookie and begin to use it.
When the cookie_worker finally runs, it will see the LRU_DISCARD flag
set, transition the cookie->state to LRU_DISCARDING, which will then
withdraw the cookie. Once the cookie is withdrawn the object is removed
the below oops will occur because the object associated with the cookie
is now NULL.
Fix the oops by clearing the LRU_DISCARD bit if another thread uses the
cookie before the cookie_worker runs.

rxrpc: Make the I/O thread take over the call and local processor work
Move the functions from the call->processor and local->processor work items into the domain of the I/O thread. The call event processor, now called from the I/O thread, then takes over the job of cranking the call state machine, processing incoming packets and transmitting DATA, ACK and ABORT packets. In a future patch, rxrpc_send_ACK() will transmit the ACK on the spot rather than queuing it for later transmission. The call event processor becomes purely received-skb driven. It only transmits things in response to events. We use "pokes" to queue a dummy skb to make it do things like start/resume transmitting data. Timer expiry also results in pokes. The connection event processor, becomes similar, though crypto events, such as dealing with CHALLENGE and RESPONSE packets is offloaded to a work item to avoid doing crypto in the I/O thread. The local event processor is removed and VERSION response packets are generated directly from the packet parser. Similarly, ABORTs generated in response to protocol errors will be transmitted immediately rather than being pushed onto a queue for later transmission.

This will allow DATA transmission to be driven directly by incoming ACKs, pokes and timers as those are processed. The Tx queue is also split: The queue of packets prepared by sendmsg is now places in call->tx_sendmsg and the packet dispatcher decants the packets into call->tx_buffer as space becomes available in the transmission window. This allows sendmsg to run ahead of the available space to try and prevent an underflow in transmission.

rxrpc: Don't hold a ref for connection workqueue
Currently, rxrpc gives the connection's work item a ref on the connection when it queues it - and this is called from the timer expiration function. The problem comes when queue_work() fails (ie. the work item is already queued): the timer routine must put the ref - but this may cause the cleanup code to run. This has the unfortunate effect that the cleanup code may then be run in softirq context - which means that any spinlocks it might need to touch have to be guarded to disable softirqs (ie. they need a "_bh" suffix). (1) Don't give a ref to the work item. (2) Simplify handling of service connections by adding a separate active count so that the refcount isn't also used for this. (3) Connection destruction for both client and service connections can then be cleaned up by putting rxrpc_put_connection() out of line and making a tidy progression through the destruction code (offloaded to a workqueue if put from softirq or processor function context). The RCU part of the cleanup then only deals with the freeing at the end. (4) Make rxrpc_queue_conn() return immediately if it sees the active count is -1 rather then queuing the connection. (5) Make sure that the cleanup routine waits for the work item to complete. (6) Stash the rxrpc_net pointer in the conn struct so that the rcu free routine can use it, even if the local endpoint has been freed. Unfortunately, neither the timer nor the work item can simply get around the problem by just using refcount_inc_not_zero() as the waits would still have to be done, and there would still be the possibility of having to put the ref in the expiration function. Note the connection work item is mostly going to go away with the main event work being transferred to the I/O thread, so the wait in (6) will become obsolete.

rxrpc: Don't hold a ref for call timer or workqueue
Currently, rxrpc gives the call timer a ref on the call when it starts it and this is passed along to the workqueue by the timer expiration function. The problem comes when queue_work() fails (ie. the work item is already queued): the timer routine must put the ref - but this may cause the cleanup code to run. This has the unfortunate effect that the cleanup code may then be run in softirq context - which means that any spinlocks it might need to touch have to be guarded to disable softirqs (ie. they need a "_bh" suffix). Fix this by: (1) Don't give a ref to the timer. (2) Making the expiration function not do anything if the refcount is 0. Note that this is more of an optimisation. (3) Make sure that the cleanup routine waits for timer to complete. However, this has a consequence that timer cannot give a ref to the work item. Therefore the following fixes are also necessary: (4) Don't give a ref to the work item. (5) Make the work item return asap if it sees the ref count is 0. (6) Make sure that the cleanup routine waits for the work item to complete. Unfortunately, neither the timer nor the work item can simply get around the problem by just using refcount_inc_not_zero() as the waits would still have to be done, and there would still be the possibility of having to put the ref in the expiration function.
