====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Remove unused variable causing compilation warning in nft_set_rbtree,
   from Yang Li. This unused variable is a left over from previous
   merge window.

2) Possible return of uninitialized in nf_conntrack_bridge, from
   Linkui Xiao. This is there since nf_conntrack_bridge is available.

3) Fix incorrect pointer math in nft_byteorder, from Dan Carpenter.
   Problem has been there since 2016.

4) Fix bogus error in destroy set element command. Problem is there
   since this new destroy command was added.

5) Fix race condition in ipset between swap and destroy commands and
   add/del/test control plane. This problem is there since ipset was
   merged.

6) Split async and sync catchall GC in two function to fix unsafe
   iteration over RCU. This is a fix-for-fix that was included in
   the previous pull request.

7cd5af0e93 net: sched: do not offload flows with a helper in act_ct
There is no hardware supporting ct helper offload. However, prior to this
patch, a flower filter with a helper in the ct action can be successfully
set into the HW, for example (eth1 is a bnxt NIC):

  # tc qdisc add dev eth1 ingress_block 22 ingress
  # tc filter add block 22 proto ip flower skip_sw ip_proto tcp \
    dst_port 21 ct_state -trk action ct helper ipv4-tcp-ftp
  # tc filter show dev eth1 ingress

    filter block 22 protocol ip pref 49152 flower chain 0 handle 0x1
      eth_type ipv4
      ip_proto tcp
      dst_port 21
      ct_state -trk
      skip_sw
      in_hw in_hw_count 1   <----
        action order 1: ct zone 0 helper ipv4-tcp-ftp pipe
         index 2 ref 1 bind 1
        used_hw_stats delayed

This might cause the flower filter not to work as expected in the HW.

This patch avoids this problem by simply returning -EOPNOTSUPP in
tcf_ct_offload_act_setup() to not allow to offload flows with a helper
in act_ct.

1fda5bb66a bpf: Do not allocate percpu memory at init stage
Kirill Shutemov reported significant percpu memory consumption increase after
booting in 288-cpu VM ([1]) due to commit 41a5db8d81 ("bpf: Add support for
non-fix-size percpu mem allocation"). The percpu memory consumption is
increased from 111MB to 969MB. The number is from /proc/meminfo.

I tried to reproduce the issue with my local VM which at most supports upto
255 cpus. With 252 cpus, without the above commit, the percpu memory
consumption immediately after boot is 57MB while with the above commit the
percpu memory consumption is 231MB.

This is not good since so far percpu memory from bpf memory allocator is not
widely used yet. Let us change pre-allocation in init stage to on-demand
allocation when verifier detects there is a need of percpu memory for bpf
program. With this change, percpu memory consumption after boot can be reduced
signicantly.

c301f0981f netfilter: nf_tables: fix pointer math issue in nft_byteorder_eval()
The problem is in nft_byteorder_eval() where we are iterating through a
loop and writing to dst[0], dst[1], dst[2] and so on...  On each
iteration we are writing 8 bytes.  But dst[] is an array of u32 so each
element only has space for 4 bytes.  That means that every iteration
overwrites part of the previous element.

I spotted this bug while reviewing commit caf3ef7468 ("netfilter:
nf_tables: prevent OOB access in nft_byteorder_eval") which is a related
issue.  I think that the reason we have not detected this bug in testing
is that most of time we only write one element.

686464514f xen/events: reduce externally visible helper functions
get_evtchn_to_irq() has only one external user while irq_from_evtchn()
provides the same functionality and is exported for a wider user base.
Modify the only external user of get_evtchn_to_irq() to use
irq_from_evtchn() instead and make get_evtchn_to_irq() static.

evtchn_from_irq() and irq_from_virq() have a single external user and
can easily be combined to a new helper irq_evtchn_from_virq() allowing
to drop irq_from_virq() and to make evtchn_from_irq() static.

5c0930ccaa hrtimers: Push pending hrtimers away from outgoing CPU earlier
2b8272ff4a ("cpu/hotplug: Prevent self deadlock on CPU hot-unplug")
solved the straight forward CPU hotplug deadlock vs. the scheduler
bandwidth timer. Yu discovered a more involved variant where a task which
has a bandwidth timer started on the outgoing CPU holds a lock and then
gets throttled. If the lock required by one of the CPU hotplug callbacks
the hotplug operation deadlocks because the unthrottling timer event is not
handled on the dying CPU and can only be recovered once the control CPU
reaches the hotplug state which pulls the pending hrtimers from the dead
CPU.

Solve this by pushing the hrtimers away from the dying CPU in the dying
callbacks. Nothing can queue a hrtimer on the dying CPU at that point because
all other CPUs spin in stop_machine() with interrupts disabled and once the
operation is finished the CPU is marked offline.

spi: Fix null dereference on suspend
A race condition exists where a synchronous (noqueue) transfer can be
active during a system suspend. This can cause a null pointer
dereference exception to occur when the system resumes.

Example order of events leading to the exception:
1. spi_sync() calls __spi_transfer_message_noqueue() which sets
   ctlr->cur_msg
2. Spi transfer begins via spi_transfer_one_message()
3. System is suspended interrupting the transfer context
4. System is resumed
6. spi_controller_resume() calls spi_start_queue() which resets cur_msg
   to NULL
7. Spi transfer context resumes and spi_finalize_current_message() is
   called which dereferences cur_msg (which is now NULL)

Wait for synchronous transfers to complete before suspending by
acquiring the bus mutex and setting/checking a suspend flag.

abc28463c8 kprobes: unify kprobes_exceptions_nofify() prototypes
Most architectures that support kprobes declare this function in their
own asm/kprobes.h header and provide an override, but some are missing
the prototype, which causes a warning for the __weak stub implementation:

kernel/kprobes.c:1865:12: error: no previous prototype for 'kprobe_exceptions_notify' [-Werror=missing-prototypes]
 1865 | int __weak kprobe_exceptions_notify(struct notifier_block *self,

Move the prototype into linux/kprobes.h so it is visible to all
the definitions.

d27abbfd48 pwm: Fix double shift bug
These enums are passed to set/test_bit().  The set/test_bit() functions
take a bit number instead of a shifted value.  Passing a shifted value
is a double shift bug like doing BIT(BIT(1)).  The double shift bug
doesn't cause a problem here because we are only checking 0 and 1 but
if the value was 5 or above then it can lead to a buffer overflow.

3feb263bb5 bpf: handle ldimm64 properly in check_cfg()
ldimm64 instructions are 16-byte long, and so have to be handled
appropriately in check_cfg(), just like the rest of BPF verifier does.

This has implications in three places:
  - when determining next instruction for non-jump instructions;
  - when determining next instruction for callback address ldimm64
    instructions (in visit_func_call_insn());
  - when checking for unreachable instructions, where second half of
    ldimm64 is expected to be unreachable;

We take this also as an opportunity to report jump into the middle of
ldimm64. And adjust few test_verifier tests accordingly.

d393315244 btrfs: make OWNER_REF_KEY type value smallest among inline refs
BTRFS_EXTENT_OWNER_REF_KEY is the type of simple quotas extent owner
refs. This special inline ref goes in front of all other inline refs.

In general, inline refs have a required sorted order s.t. type never
decreases (among other requirements). This was recently reified into a
tree-checker and fsck rule, which broke simple quotas. To be fair,
though, in a sense, the new owner ref item had also violated that not
yet fully enforced requirement.

This fix brings the owner ref item into compliance with the requirement
that inline ref type never decrease.

btrfs/301 exercises this behavior and should pass again with this fix.

9bc64bd0cd net/sched: act_ct: Always fill offloading tuple iifidx
Referenced commit doesn't always set iifidx when offloading the flow to
hardware. Fix the following cases:

- nf_conn_act_ct_ext_fill() is called before extension is created with
nf_conn_act_ct_ext_add() in tcf_ct_act(). This can cause rule offload with
unspecified iifidx when connection is offloaded after only single
original-direction packet has been processed by tc data path. Always fill
the new nf_conn_act_ct_ext instance after creating it in
nf_conn_act_ct_ext_add().

- Offloading of unidirectional UDP NEW connections is now supported, but ct
flow iifidx field is not updated when connection is promoted to
bidirectional which can result reply-direction iifidx to be zero when
refreshing the connection. Fill in the extension and update flow iifidx
before calling flow_offload_refresh().

b36995b860 lsm: fix default return value for inode_getsecctx
-EOPNOTSUPP is the return value that implements a "no-op" hook, not 0.

Without this fix having only the BPF LSM enabled (with no programs
attached) can cause uninitialized variable reads in
nfsd4_encode_fattr(), because the BPF hook returns 0 without touching
the 'ctxlen' variable and the corresponding 'contextlen' variable in
nfsd4_encode_fattr() remains uninitialized, yet being treated as valid
based on the 0 return value.

706add1367 nvme: keyring: fix conditional compilation
The keyring and auth functions can be called from both the host and
the target side and are controlled by Kconfig options for each of the
combinations, but the declarations are controlled by #ifdef checks
on the shared Kconfig symbols.

This leads to link failures in combinations where one of the frontends
is built-in and the other one is a module, and the keyring code
ends up in a module that is not reachable from the builtin code:

ld: drivers/nvme/host/core.o: in function `nvme_core_exit':
core.c:(.exit.text+0x4): undefined reference to `nvme_keyring_exit'
ld: drivers/nvme/host/core.o: in function `nvme_core_init':
core.c:(.init.text+0x94): undefined reference to `nvme_keyring_init

ld: drivers/nvme/host/tcp.o: in function `nvme_tcp_setup_ctrl':
tcp.c:(.text+0x4c18): undefined reference to `nvme_tls_psk_default'

Address this by moving nvme_keyring_init()/nvme_keyring_exit() into
module init/exit functions for the keyring module.

Merge tag 'vfs-6.7.fsid' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs fanotify fsid updates from Christian Brauner:
 "This work is part of the plan to enable fanotify to serve as a drop-in
  replacement for inotify. While inotify is availabe on all filesystems,
  fanotify currently isn't.

  In order to support fanotify on all filesystems two things are needed:

   (1) all filesystems need to support AT_HANDLE_FID

   (2) all filesystems need to report a non-zero f_fsid

  This contains (1) and allows filesystems to encode non-decodable file
  handlers for fanotify without implementing any exportfs operations by
  encoding a file id of type FILEID_INO64_GEN from i_ino and
  i_generation.

  Filesystems that want to opt out of encoding non-decodable file ids
  for fanotify that don't support NFS export can do so by providing an
  empty export_operations struct.

  This also partially addresses (2) by generating f_fsid for simple
  filesystems as well as freevxfs. Remaining filesystems will be dealt
  with by separate patches.

  Finally, this contains the patch from the current exportfs maintainers
  which moves exportfs under vfs with Chuck, Jeff, and Amir as
  maintainers and vfs.git as tree"

c9d01179e1 Second bcachefs pull request for 6.7-rc1
Here's the second big bcachefs pull request. This brings your tree up to
 date with my master branch, which is what existing bcachefs users are
 currently running.
 
 All but the last few patches have been in linux-next, those being small
 fixes. Test results from my dashboard:
   https://evilpiepirate.org/~testdashboard/ci?commit=c7046ed0cf9bb33599aa7e72e7b67bba4be42d64
 
 New features:
  - rebalance_work btree (and metadata version 1.3): the rebalance thread
    no longer has to scan to find extents that need processing - big
    scalability improvement.
  - sb_errors superblock section: this adds counters for each fsck error
    type, since filesystem creation, along with the date of the most
    recent error. It'll get us better bug reports (since users do not
    typically report errors that fsck was able to fix), and I might add
    telemetry for this in the future.
 
 Fixes include:
  - multiple snapshot deletion fixes
  - members_v2 fixups
  - deleted_inodes btree fixes
  - copygc thread no longer spins when a device is full but has no
    fragmented buckets (i.e. rebalance needs to move data around instead)
  - a fix for a memory reclaim issue with the btree key cache: we're now
    careful not to hold the srcu read lock that blocks key cache reclaim
    for too long
  - an early allocator locking fix, from Brian
  - endianness fixes, from Brian
  - CONFIG_BCACHEFS_DEBUG_TRANSACTIONS no longer defaults to y, a big
    performance improvement on multithreaded workloads

6affe08aea nvme: common: make keyring and auth separate modules
When only the keyring module is included but auth is not, modpost
complains about the lack of a module license tag:

ERROR: modpost: missing MODULE_LICENSE() in drivers/nvme/common/nvme-common.o

Address this by making both modules buildable standalone,
removing the now unnecessary CONFIG_NVME_COMMON symbol
in the process.

Also, now that NVME_KEYRING config symbol can be either a module or
built-in, the stubs need to check for '#if IS_ENABLED' rather than a
simple '#ifdef'.
