6e98b09da9 Networking changes for 6.4. 
Core
 ----
 
  - Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
    default value allows for better BIG TCP performances.
 
  - Reduce compound page head access for zero-copy data transfers.
 
  - RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible.
 
  - Threaded NAPI improvements, adding defer skb free support and unneeded
    softirq avoidance.
 
  - Address dst_entry reference count scalability issues, via false
    sharing avoidance and optimize refcount tracking.
 
  - Add lockless accesses annotation to sk_err[_soft].
 
  - Optimize again the skb struct layout.
 
  - Extends the skb drop reasons to make it usable by multiple
    subsystems.
 
  - Better const qualifier awareness for socket casts.
 
 BPF
 ---
 
  - Add skb and XDP typed dynptrs which allow BPF programs for more
    ergonomic and less brittle iteration through data and variable-sized
    accesses.
 
  - Add a new BPF netfilter program type and minimal support to hook
    BPF programs to netfilter hooks such as prerouting or forward.
 
  - Add more precise memory usage reporting for all BPF map types.
 
  - Adds support for using {FOU,GUE} encap with an ipip device operating
    in collect_md mode and add a set of BPF kfuncs for controlling encap
    params.
 
  - Allow BPF programs to detect at load time whether a particular kfunc
    exists or not, and also add support for this in light skeleton.
 
  - Bigger batch of BPF verifier improvements to prepare for upcoming BPF
    open-coded iterators allowing for less restrictive looping capabilities.
 
  - Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF
    programs to NULL-check before passing such pointers into kfunc.
 
  - Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in
    local storage maps.
 
  - Enable RCU semantics for task BPF kptrs and allow referenced kptr
    tasks to be stored in BPF maps.
 
  - Add support for refcounted local kptrs to the verifier for allowing
    shared ownership, useful for adding a node to both the BPF list and
    rbtree.
 
  - Add BPF verifier support for ST instructions in convert_ctx_access()
    which will help new -mcpu=v4 clang flag to start emitting them.
 
  - Add ARM32 USDT support to libbpf.
 
  - Improve bpftool's visual program dump which produces the control
    flow graph in a DOT format by adding C source inline annotations.
 
 Protocols
 ---------
 
  - IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
    indicates the provenance of the IP address.
 
  - IPv6: optimize route lookup, dropping unneeded R/W lock acquisition.
 
  - Add the handshake upcall mechanism, allowing the user-space
    to implement generic TLS handshake on kernel's behalf.
 
  - Bridge: support per-{Port, VLAN} neighbor suppression, increasing
    resilience to nodes failures.
 
  - SCTP: add support for Fair Capacity and Weighted Fair Queueing
    schedulers.
 
  - MPTCP: delay first subflow allocation up to its first usage. This
    will allow for later better LSM interaction.
 
  - xfrm: Remove inner/outer modes from input/output path. These are
    not needed anymore.
 
  - WiFi:
    - reduced neighbor report (RNR) handling for AP mode
    - HW timestamping support
    - support for randomized auth/deauth TA for PASN privacy
    - per-link debugfs for multi-link
    - TC offload support for mac80211 drivers
    - mac80211 mesh fast-xmit and fast-rx support
    - enable Wi-Fi 7 (EHT) mesh support
 
 Netfilter
 ---------
 
  - Add nf_tables 'brouting' support, to force a packet to be routed
    instead of being bridged.
 
  - Update bridge netfilter and ovs conntrack helpers to handle
    IPv6 Jumbo packets properly, i.e. fetch the packet length
    from hop-by-hop extension header. This is needed for BIT TCP
    support.
 
  - The iptables 32bit compat interface isn't compiled in by default
    anymore.
 
  - Move ip(6)tables builtin icmp matches to the udptcp one.
    This has the advantage that icmp/icmpv6 match doesn't load the
    iptables/ip6tables modules anymore when iptables-nft is used.
 
  - Extended netlink error report for netdevice in flowtables and
    netdev/chains. Allow for incrementally add/delete devices to netdev
    basechain. Allow to create netdev chain without device.
 
 Driver API
 ----------
 
  - Remove redundant Device Control Error Reporting Enable, as PCI core
    has already error reporting enabled at enumeration time.
 
  - Move Multicast DB netlink handlers to core, allowing devices other
    then bridge to use them.
 
  - Allow the page_pool to directly recycle the pages from safely
    localized NAPI.
 
  - Implement lockless TX queue stop/wake combo macros, allowing for
    further code de-duplication and sanitization.
 
  - Add YNL support for user headers and struct attrs.
 
  - Add partial YNL specification for devlink.
 
  - Add partial YNL specification for ethtool.
 
  - Add tc-mqprio and tc-taprio support for preemptible traffic classes.
 
  - Add tx push buf len param to ethtool, specifies the maximum number
    of bytes of a transmitted packet a driver can push directly to the
    underlying device.
 
  - Add basic LED support for switch/phy.
 
  - Add NAPI documentation, stop relaying on external links.
 
  - Convert dsa_master_ioctl() to netdev notifier. This is a preparatory
    work to make the hardware timestamping layer selectable by user
    space.
 
  - Add transceiver support and improve the error messages for CAN-FD
    controllers.

Merge tag 'for-6.4/io_uring-2023-04-21' of git://git.kernel.dk/linux

Pull io_uring updates from Jens Axboe:

 - Cleanup of the io-wq per-node mapping, notably getting rid of it so
   we just have a single io_wq entry per ring (Breno)

 - Followup to the above, move accounting to io_wq as well and
   completely drop struct io_wqe (Gabriel)

 - Enable KASAN for the internal io_uring caches (Breno)

 - Add support for multishot timeouts. Some applications use timeouts to
   wake someone waiting on completion entries, and this makes it a bit
   easier to just have a recurring timer rather than needing to rearm it
   every time (David)

 - Support archs that have shared cache coloring between userspace and
   the kernel, and hence have strict address requirements for mmap'ing
   the ring into userspace. This should only be parisc/hppa. (Helge, me)

 - XFS has supported O_DIRECT writes without needing to lock the inode
   exclusively for a long time, and ext4 now supports it as well. This
   is true for the common cases of not extending the file size. Flag the
   fs as having that feature, and utilize that to avoid serializing
   those writes in io_uring (me)

 - Enable completion batching for uring commands (me)

 - Revert patch adding io_uring restriction to what can be GUP mapped or
   not. This does not belong in io_uring, as io_uring isn't really
   special in this regard. Since this is also getting in the way of
   cleanups and improvements to the GUP code, get rid of if (me)

 - A few series greatly reducing the complexity of registered resources,
   like buffers or files. Not only does this clean up the code a lot,
   the simplified code is also a LOT more efficient (Pavel)

 - Series optimizing how we wait for events and run task_work related to
   it (Pavel)

 - Fixes for file/buffer unregistration with DEFER_TASKRUN (Pavel)

 - Misc cleanups and improvements (Pavel, me)

5c7ecada25 f2fs update for 6.4-rc1 
In this round, we've mainly modified to support non-power-of-two zone size,
 which is not required for f2fs by design. In order to avoid arch dependency,
 we refactored the messy rb_entry structure shared across different extent_cache.
 In addition to the improvement, we've also fixed several subtle bugs and
 error cases.
 
 Enhancement:
 - support non-power-of-two zone size for zoned device
 - remove sharing the rb_entry structure in extent cache
 - refactor f2fs_gc to call checkpoint in urgent condition
 - support iopoll
 
 Bug fix:
 - fix potential corruption when moving a directory
 - fix to avoid use-after-free for cached IPU bio
 - fix the folio private usage
 - avoid kernel warnings or panics in the cp_error case
 - fix to recover quota data correctly
 - fix some bugs in atomic operations
 - fix system crash due to lack of free space in LFS
 - fix null pointer panic in tracepoint in __replace_atomic_write_block
 - fix iostat lock protection
 - fix scheduling while atomic in decompression path
 - preserve direct write semantics when buffering is forced
 - fix to call f2fs_wait_on_page_writeback() in f2fs_write_raw_pages()

Pull btrfs updates from David Sterba:
 "Mostly core changes and cleanups, some notable fixes and two
  performance improvements in directory logging.

  The IO path cleanups are removing or refactoring old code, scrub main
  loop has been completely rewritten also refactoring old code.

  There are some changes to non-btrfs code, mostly trivial, the cgroup
  punt bio logic is only moved from generic code.

  Performance improvements:

   - improve logging changes in a directory during one transaction,
     avoid iterating over items and reduce lock contention (fsync time
     4x lower)

   - when logging directory entries during one transaction, reduce
     locking of subvolume trees by checking tree-log instead
     (improvement in throughput and latency for concurrent access to a
     subvolume)

  Notable fixes:

   - dev-replace:
      - properly honor read mode when requested to avoid reading from
        source device
      - target device won't be used for eventual read repair, this is
        unreliable for NODATASUM files
      - when there are unpaired (and unrepairable) metadata during
        replace, exit early with error and don't try to finish whole
        operation

   - scrub ioctl properly rejects unknown flags

   - fix global block reserve calculations

   - fix partial direct io write when there's a page fault in the
     middle, iomap will try to continue with partial request but the
     btrfs part did not match that, this can lead to zeros written
     instead of data

  Core changes:

   - io path:
      - continued cleanups and refactoring around bio handling
      - extent io submit path simplifications and cleanups
      - flush write path simplifications and cleanups
      - rework logic of passing sync mode of bio, with further cleanups

   - rewrite scrub code flow, restructure how the stripes are enumerated
     and verified in a more unified way

   - allow to set lower threshold for block group reclaim in debug mode
     to aid zoned mode testing

   - remove obsolete time-based delayed ref throttling logic when
     truncating items

   - DREW locks are not using percpu variables anymore

   - more warning fixes (-Wmaybe-uninitialized)

   - u64 division simplifications

   - error handling improvements

  Non-btrfs code changes:

   - push cgroup punt bio logic to btrfs code (there was no other user
     of that), the functionality can be now selected separately by
     BLK_CGROUP_PUNT_BIO

   - crc32c_impl removed after removing last uses in btrfs code

   - add btrfs_assertfail() to objtool table"

0cfcde1faf There are a number of major cleanups in ext4 this cycle: 
* The data=journal writepath has been significantly cleaned up and
   simplified, and reduces a large number of data=journal special cases
   by Jan Kara.
 
 * Ojaswin Muhoo has replaced linked list used to track extents that
   have been used for inode preallocation with a red-black tree in the
   multi-block allocator.  This improves performance for workloads
   which do a large number of random allocating writes.
 
 * Thanks to Kemeng Shi for a lot of cleanup and bug fixes in the
   multi-block allocator.
 
 * Matthew wilcox has converted the code paths for reading and writing

644f6bf762 gfs2: gfs2_ail_empty_gl no log flush on error 
Before this patch, function gfs2_ail_empty_gl called gfs2_log_flush even
in cases where it encountered an error. It should probably skip the log
flush and leave the file system in an inconsistent state, letting a
subsequent withdraw force the journal to be replayed to reestablish
metadata consistency.

b97e583caa gfs2: Issue message when revokes cannot be written 
Before this patch, function gfs2_ail_empty_gl would silently return an
error to the caller. This would get silently set into sd_log_error which
would cause a withdraw, but there was no indication why the file system
was withdrawn. This patch adds a fs_err to log the appropriate error
message.

68ca088dc1 gfs2: Perform second log flush in gfs2_make_fs_ro 
Before this patch, function gfs2_make_fs_ro called gfs2_log_flush once to
finalize the log. However, if there's dirty metadata, log flushes tend
to sync the metadata and formulate revokes. Before this patch, those
revokes may not be written out to the journal immediately, which meant
unresolved glocks could still have revokes in their ail lists. When the
glock worker runs, it tries to transition the glock, but the unresolved
revokes in the ail still need to be written, so it tries to start a
transaction. It's impossible to start a transaction because at that
point, the SDF_JOURNAL_LIVE flag has been cleared by gfs2_make_fs_ro.
That causes the glock worker to fail, unable to write the revokes. The
calling sequence looked something like this:

gfs2_make_fs_ro
   gfs2_log_flush - with GFS2_LOG_HEAD_FLUSH_SHUTDOWN flag set
	if (flags & GFS2_LOG_HEAD_FLUSH_SHUTDOWN)
		clear_bit(SDF_JOURNAL_LIVE, &sdp->sd_flags);
...meanwhile...
glock_work_func
   do_xmote
      rgrp_go_sync (or possibly inode_go_sync)
         ...
         gfs2_ail_empty_gl
            __gfs2_trans_begin
               if (unlikely(!test_bit(SDF_JOURNAL_LIVE, &sdp->sd_flags))) {
               ...
                  return -EROFS;

The previous patch in the series ("gfs2: return errors from
gfs2_ail_empty_gl") now causes the transaction error to no longer be
ignored, so it causes a warning from MOST of the xfstests:

WARNING: CPU: 11 PID: X at fs/gfs2/super.c:603 gfs2_put_super [gfs2]

which corresponds to:

WARN_ON(gfs2_withdrawing(sdp));

The withdraw was triggered silently from do_xmote by:

	if (unlikely(sdp->sd_log_error && !gfs2_withdrawn(sdp)))
		gfs2_withdraw_delayed(sdp);

This patch adds a second log_flush to gfs2_make_fs_ro: one to sync the
data and one to sync any outstanding revokes and finalize the journal.
Note that both of these log flushes need to be "special," in other
words, not GFS2_LOG_HEAD_FLUSH_NORMAL.

24ab158298 gfs2: return errors from gfs2_ail_empty_gl 
Before this patch, function gfs2_ail_empty_gl did not return errors it
encountered from __gfs2_trans_begin. Those errors usually came from the
fact that the file system was made read-only, often due to unmount
(but theoretically could be due to -o remount,ro), which prevented
the transaction from starting.

The inability to start a transaction prevented its revokes from being
properly written to the journal for glocks during unmount (and
transition to ro).

That meant glocks could be unlocked without the metadata properly
revoked in the journal. So other nodes could grab the glock thinking
that their lvb values were correct, but in fact corresponded to the
glock without its revokes properly synced. That presented as lvb
mismatch errors.

This patch allows gfs2_ail_empty_gl to return the error properly to
the caller.

Pull erofs updates from Gao Xiang:
 "In this cycle, sub-page block support for uncompressed files is
  available. It's mainly used to enable original signing ('golden')
  4k-block images on arm64 with 16/64k pages. In addition, end users
  could also use this feature to build a manifest to directly refer to
  golden tar data.

  Besides, long xattr name prefix support is also introduced in this
  cycle to avoid too many xattrs with the same prefix (e.g. overlayfs
  xattrs). It's useful for erofs + overlayfs combination (like Composefs
  model): the image size is reduced by ~14% and runtime performance is
  also slightly improved.

  Others are random fixes and cleanups as usual.

Pull misc vfs updates from Christian Brauner:
 "This contains a pile of various smaller fixes. Most of them aren't
  very interesting so this just highlights things worth mentioning:

   - Various filesystems contained the same little helper to convert
     from the mode of a dentry to the DT_* type of that dentry.

     They have now all been switched to rely on the generic
     fs_umode_to_dtype() helper. All custom helpers are removed (Jeff)

   - Fsnotify now reports ACCESS and MODIFY events for splice
     (Chung-Chiang Cheng)

   - After converting timerfd a long time ago to rely on
     wait_event_interruptible_*() apis, convert eventfd as well. This
     removes the complex open-coded wait code (Wen Yang)

   - Simplify sysctl registration for devpts, avoiding the declaration
     of two tables. Instead, just use a prefixed path with
     register_sysctl() (Luis)

   - The setattr_should_drop_sgid() helper is now exported so NFS can
     use it. By switching NFS to this helper an NFS setgid inheritance
     bug is fixed (me)"

Pull acl updates from Christian Brauner:
 "After finishing the introduction of the new posix acl api last cycle
  the generic POSIX ACL xattr handlers are still around in the
  filesystems xattr handlers for two reasons:

   (1) Because a few filesystems rely on the ->list() method of the
       generic POSIX ACL xattr handlers in their ->listxattr() inode
       operation.

   (2) POSIX ACLs are only available if IOP_XATTR is raised. The
       IOP_XATTR flag is raised in inode_init_always() based on whether
       the sb->s_xattr pointer is non-NULL. IOW, the registered xattr
       handlers of the filesystem are used to raise IOP_XATTR. Removing
       the generic POSIX ACL xattr handlers from all filesystems would
       risk regressing filesystems that only implement POSIX ACL support
       and no other xattrs (nfs3 comes to mind).

  This contains the work to decouple POSIX ACLs from the IOP_XATTR flag
  as they don't depend on xattr handlers anymore. So it's now possible
  to remove the generic POSIX ACL xattr handlers from the sb->s_xattr
  list of all filesystems. This is a crucial step as the generic POSIX
  ACL xattr handlers aren't used for POSIX ACLs anymore and POSIX ACLs
  don't depend on the xattr infrastructure anymore.

  Adressing problem (1) will require more long-term work. It would be
  best to get rid of the ->list() method of xattr handlers completely at
  some point.

  For erofs, ext{2,4}, f2fs, jffs2, ocfs2, and reiserfs the nop POSIX
  ACL xattr handler is kept around so they can continue to use
  array-based xattr handler indexing.

  This update does simplify the ->listxattr() implementation of all
  these filesystems however"

Merge tag 'v6.4/pidfd.file' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull pidfd updates from Christian Brauner:
 "This adds a new pidfd_prepare() helper which allows the caller to
  reserve a pidfd number and allocates a new pidfd file that stashes the
  provided struct pid.

  It should be avoided installing a file descriptor into a task's file
  descriptor table just to close it again via close_fd() in case an
  error occurs. The fd has been visible to userspace and might already
  be in use. Instead, a file descriptor should be reserved but not
  installed into the caller's file descriptor table.

  If another failure path is hit then the reserved file descriptor and
  file can just be put without any userspace visible side-effects. And
  if all failure paths are cleared the file descriptor and file can be
  installed into the task's file descriptor table.

  This helper is now used in all places that open coded this
  functionality before. For example, this is currently done during
  copy_process() and fanotify used pidfd_create(), which returns a pidfd
  that has already been made visibile in the caller's file descriptor
  table, but then closed it using close_fd().

  In one of the next merge windows there is also new functionality
  coming to unix domain sockets that will have to rely on
  pidfd_prepare()"

   the RCU entry and Zqiang being added as an RCU reviewer.

   I have also transitioned from reviewer to maintainer; however, Paul
   will be taking over sending RCU pull-requests for the next merge
   window.

 - Resolution of hotplug warning in nohz code, achieved by fixing
   cpu_is_hotpluggable() through interaction with the nohz subsystem.

   Tick dependency modifications by Zqiang, focusing on fixing usage of
   the TICK_DEP_BIT_RCU_EXP bitmask.

 - Avoid needless calls to the rcu-lazy shrinker for CONFIG_RCU_LAZY=n
   kernels, fixed by Zqiang.

 - Improvements to rcu-tasks stall reporting by Neeraj.

 - Initial renaming of k[v]free_rcu() to k[v]free_rcu_mightsleep() for
   increased robustness, affecting several components like mac802154,
   drbd, vmw_vmci, tracing, and more.

   A report by Eric Dumazet showed that the API could be unknowingly
   used in an atomic context, so we'd rather make sure they know what
   they're asking for by being explicit:

      https://lore.kernel.org/all/20221202052847.2623997-1-edumazet@google.com/

 - Documentation updates, including corrections to spelling,
   clarifications in comments, and improvements to the srcu_size_state
   comments.

 - Better srcu_struct cache locality for readers, by adjusting the size
   of srcu_struct in support of SRCU usage by Christoph Hellwig.

 - Teach lockdep to detect deadlocks between srcu_read_lock() vs
   synchronize_srcu() contributed by Boqun.

   Previously lockdep could not detect such deadlocks, now it can.

 - Integration of rcutorture and rcu-related tools, targeted for v6.4
   from Boqun's tree, featuring new SRCU deadlock scenarios, test_nmis
   module parameter, and more

Merge tag 'lsm-pr-20230420' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull lsm updates from Paul Moore:

 - Move the LSM hook comment blocks into security/security.c

   For many years the LSM hook comment blocks were located in a very odd
   place, include/linux/lsm_hooks.h, where they lived on their own,
   disconnected from both the function prototypes and definitions.

   In keeping with current kernel conventions, this moves all of these
   comment blocks to the top of the function definitions, transforming
   them into the kdoc format in the process. This should make it much
   easier to maintain these comments, which are the main source of LSM
   hook documentation.

   For the most part the comment contents were left as-is, although some
   glaring errors were corrected. Expect additional edits in the future
   as we slowly update and correct the comment blocks.

   This is the bulk of the diffstat.

 - Introduce LSM_ORDER_LAST

   Similar to how LSM_ORDER_FIRST is used to specify LSMs which should
   be ordered before "normal" LSMs, the LSM_ORDER_LAST is used to
   specify LSMs which should be ordered after "normal" LSMs.

   This is one of the prerequisites for transitioning IMA/EVM to a
   proper LSM.

 - Remove the security_old_inode_init_security() hook

   The security_old_inode_init_security() LSM hook only allows for a
   single xattr which is problematic both for LSM stacking and the
   IMA/EVM-as-a-LSM effort. This finishes the conversion over to the
   security_inode_init_security() hook and removes the single-xattr LSM
   hook.

 - Fix a reiserfs problem with security xattrs

   During the security_old_inode_init_security() removal work it became
   clear that reiserfs wasn't handling security xattrs properly so we
   fixed it.

e0416e7d33 rxrpc: Fix potential race in error handling in afs_make_call() 
If the rxrpc call set up by afs_make_call() receives an error whilst it is
transmitting the request, there's the possibility that it may get to the
point the rxrpc call is ended (after the error_kill_call label) just as the
call is queued for async processing.

This could manifest itself as call->rxcall being seen as NULL in
afs_deliver_to_call() when it tries to lock the call.

Fix this by splitting rxrpc_kernel_end_call() into a function to shut down
an rxrpc call and a function to release the caller's reference and calling
the latter only when we get to afs_put_call().

Pull btrfs fixes from David Sterba:
 "Two patches fixing the problem with aync discard.

  The default settings had a low IOPS limit and processing a large batch
  to discard would take a long time. On laptops this can cause increased
  power consumption due to disk activity.

  As async discard has been on by default since 6.2 this likely affects
  a lot of users.

  Summary:

   - increase the default IOPS limit 10x which reportedly helped

   - setting the sysfs IOPS value to 0 now does not throttle anymore
     allowing the discards to be processed at full speed. Previously
     there was an arbitrary 6 hour target for processing the pending
     batch"

7a40f1f18a fs: dlm: stop unnecessarily filling zero ms_extra bytes 
Commit 7175e131eb ("fs: dlm: fix invalid derefence of sb_lvbptr")
fixes an issue when the lkb->lkb_lvbptr set to an dangled pointer and an
followed memcpy() would fail. It was fixed by an additional check of
DLM_LKF_VALBLK flag. The mentioned commit forgot to add an additional check
if DLM_LKF_VALBLK is set for the additional amount of LVB data allocated
in a dlm message. This patch is changing the message allocation to check
additionally if DLM_LKF_VALBLK is set otherwise a dangled lkb->lkb_lvbptr
pointer would allocated zero LVB message data which not gets filled with
actual data.

This patch is however only a cleanup to reduce the amount of zero bytes
transmitted over network as receive_lvb() will only evaluates message LVB
data if DLM_LKF_VALBLK is set.

ef9cddfe57 btrfs: reinterpret async discard iops_limit=0 as no delay 
Currently, a limit of 0 results in a hard coded metering over 6 hours.
Since the default is a set limit, I suspect no one truly depends on this
rather arbitrary setting. Repurpose it for an arguably more useful
"unlimited" mode, where the delay is 0.

Note that if block groups are too new, or go fully empty, there is still
a delay associated with those conditions. Those delays implement
heuristics for not trimming a region we are relatively likely to fully
overwrite soon.

e9f59429b8 btrfs: set default discard iops_limit to 1000 
Previously, the default was a relatively conservative 10. This results
in a 100ms delay, so with ~300 discards in a commit, it takes the full
30s till the next commit to finish the discards. On a workstation, this
results in the disk never going idle, wasting power/battery, etc.

Set the default to 1000, which results in using the smallest possible
delay, currently, which is 1ms. This has shown to not pathologically
keep the disk busy by the original reporter.
