The in_atomic macro cannot always detect atomic context. In particular,
e113410 
it cannot know about held spinlocks in non-preemptible kernels. Although,
there is no user call bpf_link_put() with holding spinlock now. Be the
safe side, we can avoid this in the feature.

btrfs: zoned: traverse devices under chunk_mutex in btrfs_can_activat…
0b9e667 
…e_zone

btrfs_can_activate_zone() can be called with the device_list_mutex already
held, which will lead to a deadlock:

insert_dev_extents() // Takes device_list_mutex
`-> insert_dev_extent()
 `-> btrfs_insert_empty_item()
  `-> btrfs_insert_empty_items()
   `-> btrfs_search_slot()
    `-> btrfs_cow_block()
     `-> __btrfs_cow_block()
      `-> btrfs_alloc_tree_block()
       `-> btrfs_reserve_extent()
        `-> find_free_extent()
         `-> find_free_extent_update_loop()
          `-> can_allocate_chunk()
           `-> btrfs_can_activate_zone() // Takes device_list_mutex again

Instead of using the RCU on fs_devices->device_list we
can use fs_devices->alloc_list, protected by the chunk_mutex to traverse
the list of active devices.

We are in the chunk allocation thread. The newer chunk allocation
happens from the devices in the fs_device->alloc_list protected by the
chunk_mutex.

  btrfs_create_chunk()
    lockdep_assert_held(&info->chunk_mutex);
    gather_device_info
      list_for_each_entry(device, &fs_devices->alloc_list, dev_alloc_list)

Also, a device that reappears after the mount won't join the alloc_list
yet and, it will be in the dev_list, which we don't want to consider in
the context of the chunk alloc.

wifi: brcmfmac: Fix potential NULL pointer dereference in 'brcmf_c_pr…
683b972 
…einit_dcmds()'

This patch fixes a NULL pointer dereference bug in brcmfmac that occurs
when ptr which is NULL pointer passed as an argument of strlcpy() in
brcmf_c_preinit_dcmds(). This happens when the driver passes a firmware
version string that does not contain a space " ", making strrchr()
return a null pointer. This patch adds a null pointer check.

Found by a modified version of syzkaller.

selftests/bpf: Add selftests for load-acquire and store-release instr…
c2cf73e 
…uctions

Add the following ./test_progs tests:

  * atomics/load_acquire
  * atomics/store_release
  * arena_atomics/load_acquire
  * arena_atomics/store_release

They depend on the pre-defined __BPF_FEATURE_LOAD_ACQ_STORE_REL feature
macro, which implies -mcpu>=v4.

  $ ALLOWLIST=atomics/load_acquire,atomics/store_release,
  $ ALLOWLIST+=arena_atomics/load_acquire,arena_atomics/store_release

  $ ./test_progs-cpuv4 -a $ALLOWLIST

  #3/9     arena_atomics/load_acquire:OK
  #3/10    arena_atomics/store_release:OK
...
  #10/8    atomics/load_acquire:OK
  #10/9    atomics/store_release:OK

  $ ./test_progs -v -a $ALLOWLIST

  test_load_acquire:SKIP:Clang does not support BPF load-acquire or addr_space_cast
  #3/9     arena_atomics/load_acquire:SKIP
  test_store_release:SKIP:Clang does not support BPF store-release or addr_space_cast
  #3/10    arena_atomics/store_release:SKIP
...
  test_load_acquire:SKIP:Clang does not support BPF load-acquire
  #10/8    atomics/load_acquire:SKIP
  test_store_release:SKIP:Clang does not support BPF store-release
  #10/9    atomics/store_release:SKIP

Additionally, add several ./test_verifier tests:

  #65/u atomic BPF_LOAD_ACQ access through non-pointer  OK
  #65/p atomic BPF_LOAD_ACQ access through non-pointer  OK
  #66/u atomic BPF_STORE_REL access through non-pointer  OK
  #66/p atomic BPF_STORE_REL access through non-pointer  OK

  #67/u BPF_ATOMIC load-acquire, 8-bit OK
  #67/p BPF_ATOMIC load-acquire, 8-bit OK
  #68/u BPF_ATOMIC load-acquire, 16-bit OK
  #68/p BPF_ATOMIC load-acquire, 16-bit OK
  #69/u BPF_ATOMIC load-acquire, 32-bit OK
  #69/p BPF_ATOMIC load-acquire, 32-bit OK
  #70/u BPF_ATOMIC load-acquire, 64-bit OK
  #70/p BPF_ATOMIC load-acquire, 64-bit OK
  #71/u Cannot load-acquire from uninitialized src_reg OK
  #71/p Cannot load-acquire from uninitialized src_reg OK

  #76/u BPF_ATOMIC store-release, 8-bit OK
  #76/p BPF_ATOMIC store-release, 8-bit OK
  #77/u BPF_ATOMIC store-release, 16-bit OK
  #77/p BPF_ATOMIC store-release, 16-bit OK
  #78/u BPF_ATOMIC store-release, 32-bit OK
  #78/p BPF_ATOMIC store-release, 32-bit OK
  #79/u BPF_ATOMIC store-release, 64-bit OK
  #79/p BPF_ATOMIC store-release, 64-bit OK
  #80/u Cannot store-release from uninitialized src_reg OK
  #80/p Cannot store-release from uninitialized src_reg OK
