      nfsd4: fix delegation cleanup on error · cbf7a75b
      J. Bruce Fields authored
      We're not cleaning up everything we need to on error.  In particular,
      we're not removing our lease.  Among other problems this can cause the
      struct nfs4_file used as fl_owner to be referenced after it has been
      destroyed.

      NFSD: Don't clear SUID/SGID after root writing data · 368fe39b
      Kinglong Mee authored
      We're clearing the SUID/SGID bits on write by hand in nfsd_vfs_write,
      even though the subsequent vfs_writev() call will end up doing this for
      us (through file system write methods eventually calling
      file_remove_suid(), e.g., from __generic_file_aio_write).
      
      So, remove the redundant nfsd code.
      
      The only change in behavior is when the write is by root, in which case
      we previously cleared SUID/SGID, but will now leave it alone.  The new
      behavior is the behavior of every filesystem we've checked.
      
      It seems better to be consistent with local filesystem behavior.  And
      the security advantage seems limited as root could always restore these
      bits by hand if it wanted.
      
      SUID/SGID is not cleared after writing data with (root, local ext4),

      nfsd4: remove lockowner when removing lock stateid · a1b8ff4c
      J. Bruce Fields authored
      The nfsv4 state code has always assumed a one-to-one correspondance
      between lock stateid's and lockowners even if it appears not to in some
      places.
      
      We may actually change that, but for now when FREE_STATEID releases a
      lock stateid it also needs to release the parent lockowner.
      
      Symptoms were a subsequent LOCK crashing in find_lockowner_str when it
      calls same_lockowner_ino on a lockowner that unexpectedly has an empty
      so_stateids list.

      nfsd: clean up fh_auth usage · 5409e46f
      Christoph Hellwig authored
      Use fh_fsid when reffering to the fsid part of the filehandle.  The
      variable length auth field envisioned in nfsfh wasn't ever implemented.
      Also clean up some lose ends around this and document the file handle
      format better.
      
      Btw, why do we even export nfsfh.h to userspace?  The file handle very
      much is kernel private, and nothing in nfs-utils include the header
      either.

      NFSD: Call ->set_acl with a NULL ACL structure if no entries · aa07c713
      Kinglong Mee authored
      After setting ACL for directory, I got two problems that caused
      by the cached zero-length default posix acl.
      
      This patch make sure nfsd4_set_nfs4_acl calls ->set_acl
      with a NULL ACL structure if there are no entries.
      
      Thanks for Christoph Hellwig's advice.

      sym53c8xx_2: Set DID_REQUEUE return code when aborting squeue · fd1232b2
      Mikulas Patocka authored
      This patch fixes I/O errors with the sym53c8xx_2 driver when the disk
      returns QUEUE FULL status.
      
      When the controller encounters an error (including QUEUE FULL or BUSY
      status), it aborts all not yet submitted requests in the function
      sym_dequeue_from_squeue.
      
      This function aborts them with DID_SOFT_ERROR.
      
      If the disk has full tag queue, the request that caused the overflow is
      aborted with QUEUE FULL status (and the scsi midlayer properly retries
      it until it is accepted by the disk), but the sym53c8xx_2 driver aborts
      the following requests with DID_SOFT_ERROR --- for them, the midlayer
      does just a few retries and then signals the error up to sd.
      
      The result is that disk returning QUEUE FULL causes request failures.
      
      The error was reproduced on 53c895 with COMPAQ BD03685A24 disk
      (rebranded ST336607LC) with command queue 48 or 64 tags.  The disk has
      64 tags, but under some access patterns it return QUEUE FULL when there
      are less than 64 pending tags.  The SCSI specification allows returning
      QUEUE FULL anytime and it is up to the host to retry.

      powerpc: Don't try to set LPCR unless we're in hypervisor mode · 18aa0da3
      Paul Mackerras authored
      Commit 8f619b54 ("powerpc/ppc64: Do not turn AIL (reloc-on
      interrupts) too early") added code to set the AIL bit in the LPCR
      without checking whether the kernel is running in hypervisor mode.  The
      result is that when the kernel is running as a guest (i.e., under
      PowerKVM or PowerVM), the processor takes a privileged instruction
      interrupt at that point, causing a panic.  The visible result is that
      the kernel hangs after printing "returning from prom_init".
      
      This fixes it by checking for hypervisor mode being available before
      setting LPCR.  If we are not in hypervisor mode, we enable relocation-on
      interrupts later in pSeries_setup_arch using the H_SET_MODE hcall.

      futex: update documentation for ordering guarantees · d7e8af1a
      Davidlohr Bueso authored
      Commits 11d4616b ("futex: revert back to the explicit waiter
      counting code") and 69cd9eba ("futex: avoid race between requeue and
      wake") changed some of the finer details of how we think about futexes.
      One was a late fix and the other a consequence of overlooking the whole
      requeuing logic.
      
      The first change caused our documentation to be incorrect, and the
      second made us aware that we need to explicitly add more details to it.

       2) L2TP PPP connect code takes PMTU from the wrong socket, fix from
          Dmitry Petukhov.
      
       3) UFO and TSO packets differ in whether they include the protocol
          header in gso_size, account for that in skb_gso_transport_seglen().
         From Florian Westphal.
      
       4) If VLAN untagging fails, we double free the SKB in the bridging
          output path.  From Toshiaki Makita.
      
       5) Several call sites of sk->sk_data_ready() were referencing an SKB
          just added to the socket receive queue in order to calculate the
          second argument via skb->len.  This is dangerous because the moment
          the skb is added to the receive queue it can be consumed in another
          context and freed up.
      
          It turns out also that none of the sk->sk_data_ready()
          implementations even care about this second argument.
      
          So just kill it off and thus fix all these use-after-free bugs as a
          side effect.
      
       6) Fix inverted test in tcp_v6_send_response(), from Lorenzo Colitti.
      
       7) pktgen needs to do locking properly for LLTX devices, from Daniel
          Borkmann.
      
       8) xen-netfront driver initializes TX array entries in RX loop :-) From
          Vincenzo Maffione.
      
       9) After refactoring, some tunnel drivers allow a tunnel to be
          configured on top itself.  Fix from Nicolas Dichtel.
