[GIT PULL] Please pull NFS client bugfixes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Linus,

The following 3 patches fix a regression in the NFS/RPC TPC re-
connection code which can cause the RPC transmission to hang. The issue
was discovered by Dave Wysochanski last week.

With this pull, we still have one more regression to fix. MIPS is
seeing data corruption due to the fact that the iovec_iter code does
not appear to call flush_dcache_page() after copying data into the bvec
pages. We need guidance from Al as to how he wants this fixed.

Cheers
  Trond

  SUNRPC: Remove xprt_connect_status() (2018-12-18 11:04:10 -0500)

----------------------------------------------------------------
NFS client bugfixes for Linux 4.20

Bugfixes:
- Fix TCP socket disconnection races by ensuring we always call
  xprt_disconnect_done() after releasing the socket.
- Fix a race when clearing both XPRT_CONNECTING and XPRT_LOCKED
- Remove xprt_connect_status() so it does not mask errors that should
  be handled by call_connect_status()

----------------------------------------------------------------
Trond Myklebust (3):
      SUNRPC: Fix disconnection races
      SUNRPC: Fix a race with XPRT_CONNECTING
      SUNRPC: Remove xprt_connect_status()
