      cifs: change format of CIFS_FULL_KEY_DUMP ioctl · 1bb56810
      Aurelien Aptel authored 
      Make CIFS_FULL_KEY_DUMP ioctl able to return variable-length keys.

* userspace needs to pass the struct size along with optional
  session_id and some space at the end to store keys
* if there is enough space kernel returns keys in the extra space and
  sets the length of each key via xyz_key_length fields

This also fixes the build error for get_user() on ARM.

Sample program:

There's probably more useful macros that we can use to print
others like flags etc. But I'll submit sepawrate patches for
those at a future date.

      cifs: set server->cipher_type to AES-128-CCM for SMB3.0 · 6d2fcfe6
      Aurelien Aptel authored 
      SMB3.0 doesn't have encryption negotiate context but simply uses
the SMB2_GLOBAL_CAP_ENCRYPTION flag.

When that flag is present in the neg response cifs.ko uses AES-128-CCM
which is the only cipher available in this context.

cipher_type was set to the server cipher only when parsing encryption
negotiate context (SMB3.1.1).

For SMB3.0 it was set to 0. This means cipher_type value can be 0 or 1
for AES-128-CCM.

Fix this by checking for SMB3.0 and encryption capability and setting
cipher_type appropriately.

      io_uring: fix data race to avoid potential NULL-deref · b16ef427
      Marco Elver authored 
      Commit ba5ef6dc ("io_uring: fortify tctx/io_wq cleanup") introduced
setting tctx->io_wq to NULL a bit earlier. This has caused KCSAN to
detect a data race between accesses to tctx->io_wq:

  write to 0xffff88811d8df330 of 8 bytes by task 3709 on cpu 1:
   io_uring_clean_tctx                  fs/io_uring.c:9042 [inline]

   exit_to_user_mode_loop               kernel/entry/common.c:171 [inline]
   ...
  read to 0xffff88811d8df330 of 8 bytes by task 6412 on cpu 0:
   io_uring_try_cancel_iowq             fs/io_uring.c:8911 [inline]

   process_one_work                     kernel/workqueue.c:2276
   ...

With the config used, KCSAN only reports data races with value changes:
this implies that in the case here we also know that tctx->io_wq was
non-NULL. Therefore, depending on interleaving, we may end up with:

              [CPU 0]                 |        [CPU 1]
  io_uring_try_cancel_iowq()          | io_uring_clean_tctx()
    if (!tctx->io_wq) // false        |   ...
    ...                               |   tctx->io_wq = NULL
    io_wq_cancel_cb(tctx->io_wq, ...) |   ...
      -> NULL-deref                   |

Note: It is likely that thus far we've gotten lucky and the compiler
optimizes the double-read into a single read into a register -- but this
is never guaranteed, and can easily change with a different config!

Fix the data race by restoring the previous behaviour, where both
setting io_wq to NULL and put of the wq are _serialized_ after
concurrent io_uring_try_cancel_iowq() via acquisition of the uring_lock
and removal of the node in io_uring_del_task_file().

      xprtrdma: Revert 586a0787 · ae605ee9
      Chuck Lever authored 
      Commit 9ed5af26 ("SUNRPC: Clean up the handling of page padding
in rpc_prepare_reply_pages()") [Dec 2020] affects RPC Replies that
have a data payload (i.e., Write chunks).

rpcrdma_prepare_readch(), as its name suggests, sets up Read chunks
which are data payloads within RPC Calls. Those payloads are
constructed by xdr_write_pages(), which continues to stuff the call
buffer's tail kvec with the payload's XDR roundup. Thus removing
the tail buffer logic in rpcrdma_prepare_readch() was the wrong
thing to do.

      NFSv4: Fix v4.0/v4.1 SEEK_DATA return -ENOTSUPP when set NFS_V4_2 config · e67afa7e
      Zhang Xiaoxu authored 
      Since commit bdcc2cd1 ("NFSv4.2: handle NFS-specific llseek errors"),
nfs42_proc_llseek would return -EOPNOTSUPP rather than -ENOTSUPP when
SEEK_DATA on NFSv4.0/v4.1.

This will lead xfstests generic/285 not run on NFSv4.0/v4.1 when set the
CONFIG_NFS_V4_2, rather than run failed.

      ALSA: hda/realtek: fix mute/micmute LEDs and speaker for HP Zbook Fury 17 G8 · 50dbfae9
      Jeremy Szu authored 
      The HP ZBook Studio 17.3 Inch G8 is using ALC285 codec which is
using 0x04 to control mute LED and 0x01 to control micmute LED.
In the other hand, there is no output from right channel of speaker.
Therefore, add a quirk to make it works.

      Pull networking fixes from Jakub Kicinski:
 "Networking fixes for 5.13-rc4, including fixes from bpf, netfilter,
  can and wireless trees. Notably including fixes for the recently
  announced "FragAttacks" WiFi vulnerabilities. Rather large batch,
  touching some core parts of the stack, too, but nothing hair-raising.

  Current release - regressions:

   - tipc: make node link identity publish thread safe

   - dsa: felix: re-enable TAS guard band mode

   - stmmac: correct clocks enabled in stmmac_vlan_rx_kill_vid()

   - stmmac: fix system hang if change mac address after interface
     ifdown

  Current release - new code bugs:

   - mptcp: avoid OOB access in setsockopt()

   - bpf: Fix nested bpf_bprintf_prepare with more per-cpu buffers

   - ethtool: stats: fix a copy-paste error - init correct array size

  Previous releases - regressions:

   - sched: fix packet stuck problem for lockless qdisc

   - net: really orphan skbs tied to closing sk

   - mlx4: fix EEPROM dump support

   - bpf: fix alu32 const subreg bound tracking on bitwise operations

   - bpf: fix mask direction swap upon off reg sign change

   - bpf, offload: reorder offload callback 'prepare' in verifier

   - stmmac: Fix MAC WoL not working if PHY does not support WoL

   - packetmmap: fix only tx timestamp on request

   - tipc: skb_linearize the head skb when reassembling msgs

  Previous releases - always broken:

   - mac80211: address recent "FragAttacks" vulnerabilities

   - mac80211: do not accept/forward invalid EAPOL frames

   - mptcp: avoid potential error message floods

   - bpf, ringbuf: deny reserve of buffers larger than ringbuf to
     prevent out of buffer writes

   - bpf: forbid trampoline attach for functions with variable arguments

   - bpf: add deny list of functions to prevent inf recursion of tracing
     programs

   - tls splice: check SPLICE_F_NONBLOCK instead of MSG_DONTWAIT

   - can: isotp: prevent race between isotp_bind() and
     isotp_setsockopt()

   - netfilter: nft_set_pipapo_avx2: Add irq_fpu_usable() check,
     fallback to non-AVX2 version

  Misc:

   - bpf: add kconfig knob for disabling unpriv bpf by default"
