      pull-request: bpf 2023-03-23
      
      We've added 8 non-merge commits during the last 13 day(s) which contain
      a total of 21 files changed, 238 insertions(+), 161 deletions(-).
      
      The main changes are:
      
      1) Fix verification issues in some BPF programs due to their stack usage
         patterns, from Eduard Zingerman.
      
      2) Fix to add missing overflow checks in xdp_umem_reg and return an error
         in such case, from Kal Conley.
      
      3) Fix and undo poisoning of strlcpy in libbpf given it broke builds for
         libcs which provided the former like uClibc-ng, from Jesus Sanchez-Palencia.
      
      4) Fix insufficient bpf_jit_limit default to avoid users running into hard
         to debug seccomp BPF errors, from Daniel Borkmann.
      
      5) Fix driver return code when they don't support a bpf_xdp_metadata kfunc
         to make it unambiguous from other errors, from Jesper Dangaard Brouer.
      
      6) Two BPF selftest fixes to address compilation errors from recent changes
         in kernel structures, from Alexei Starovoitov.

      Bluetooth: HCI: Fix global-out-of-bounds · bce56405
      Sungwoo Kim authored
      To loop a variable-length array, hci_init_stage_sync(stage) considers
      that stage[i] is valid as long as stage[i-1].func is valid.
      Thus, the last element of stage[].func should be intentionally invalid
      as hci_init0[], le_init2[], and others did.
      However, amp_init1[] and amp_init2[] have no invalid element, letting
      hci_init_stage_sync() keep accessing amp_init1[] over its valid range.
      This patch fixes this by adding {} in the last of amp_init1[] and
      amp_init2[].

      Bluetooth: btqcomsmd: Fix command timeout after setting BD address · 5d44ab9e
      Stephan Gerhold authored
      On most devices using the btqcomsmd driver (e.g. the DragonBoard 410c
      and other devices based on the Qualcomm MSM8916/MSM8909/... SoCs)
      the Bluetooth firmware seems to become unresponsive for a while after
      setting the BD address. On recent kernel versions (at least 5.17+)
      this often causes timeouts for subsequent commands, e.g. the HCI reset
      sent by the Bluetooth core during initialization:
      
          Bluetooth: hci0: Opcode 0x c03 failed: -110
      
      Unfortunately this behavior does not seem to be documented anywhere.
      Experimentation suggests that the minimum necessary delay to avoid
      the problem is ~150us. However, to be sure add a sleep for > 1ms
      in case it is a bit longer on other firmware versions.
      
      Older kernel versions are likely also affected, although perhaps with
      slightly different errors or less probability. Side effects can easily
      hide the issue in most cases, e.g. unrelated incoming interrupts that
      cause the necessary delay.

      Reinstate "GFS2: free disk inode which is deleted by remote node -V2" · 260595b4
      Bob Peterson authored
      It turns out that reverting commit 970343cd ("GFS2: free disk inode
      which is deleted by remote node -V2") causes a regression related to
      evicting inodes that were unlinked on a different cluster node.
      
      We could also have simply added a call to d_mark_dontcache() to function
      gfs2_try_evict(), but the original pre-revert code is better tested and
      proven.
      
      This reverts commit 445cb127.

      net: mdio: thunder: Add missing fwnode_handle_put() · b1de5c78
      Liang He authored
      In device_for_each_child_node(), we should add fwnode_handle_put()
      when break out of the iteration device_for_each_child_node()
      as it will automatically increase and decrease the refcounter.

      net/sched: act_api: use the correct TCA_ACT attributes in dump · fcb3a465
      Pedro Tammela authored
      4 places in the act api code are using 'TCA_' definitions where they
      should be using 'TCA_ACT_', which is confusing for the reader, although
      functionally they are equivalent.
