      nbd: ratelimit error msgs after socket close · dd37eba1
      Dan Streetman authored
      commit da6ccaaa upstream.
      
      Make the "Attempted send on closed socket" error messages generated in
      nbd_request_handler() ratelimited.
      
      When the nbd socket is shutdown, the nbd_request_handler() function emits
      an error message for every request remaining in its queue.  If the queue
      is large, this will spam a large amount of messages to the log.  There's
      no need for a separate error message for each request, so this patch
      ratelimits it.
      
      In the specific case this was found, the system was virtual and the error
      messages were logged to the serial port, which overwhelmed it.

      unbreak allmodconfig KCONFIG_ALLCONFIG=... · d6f7f96a
      Al Viro authored
      commit 6b87b70c upstream.
      
      	Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used
      to be equivalent to make allmodconfig; these days it hardwires MODULES to n.
      In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is
      treated as if it set it to n.
      
      	Regression had been introduced by commit cfa98f ("kconfig: do not
      override symbols already set"); what happens is that conf_read_simple()
      does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and
      has conf_set_all_new_symbols() skip modules_sym.
      
      	It's pretty easy to fix - simply move that call of sym_calc_value()
      into the callers, except for the ones in KCONFIG_ALLCONFIG handling.
      Objections?

      tty: Fix GPF in flush_to_ldisc(), part 2 · c4bef7cb
      Peter Hurley authored
      commit f33798de upstream.
      
      commit 9ce119f3 ("tty: Fix GPF in flush_to_ldisc()") fixed a
      GPF caused by a line discipline which does not define a receive_buf()
      method.
      
      However, the vt driver (and speakup driver also) pushes selection
      data directly to the line discipline receive_buf() method via
      tty_ldisc_receive_buf(). Fix the same problem in tty_ldisc_receive_buf().

      ASoC: s3c24xx: use const snd_soc_component_driver pointer · db9ac0f3
      Arnd Bergmann authored
      commit ba4bc32e upstream.
      
      An older patch to convert the API in the s3c i2s driver
      ended up passing a const pointer into a function that takes
      a non-const pointer, so we now get a warning:
      
      sound/soc/samsung/s3c2412-i2s.c: In function 's3c2412_iis_dev_probe':
      sound/soc/samsung/s3c2412-i2s.c:172:9: error: passing argument 3 of 's3c_i2sv2_register_component' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
      
      However, the s3c_i2sv2_register_component() function again
      passes the pointer into another function taking a const, so
      we just need to change its prototype.

      PCI: imx6: Move link up check into imx6_pcie_wait_for_link() · 92d27c4a
      Lucas Stach authored
      commit 4d107d3b upstream.
      
      imx6_pcie_link_up() previously used usleep_range() to wait for the link to
      come up.  Since it may be called while holding the config spinlock, the
      sleep causes a "BUG: scheduling while atomic" error.
      
      Instead of waiting for the link to come up in imx6_pcie_link_up(), do the
      waiting in imx6_pcie_wait_for_link(), where we're not holding a lock and
      sleeping is allowed.

      PCI: imx6: Remove broken Gen2 workaround · f5aa19a4

      commit a77c5422 upstream.
      
      Remove the remnants of the workaround for erratum ERR005184 which was never
      completely implemented.  The checks alone don't carry any value as we don't
      act properly on the result.
      
      A workaround should be added to the lane speed change in establish_link
      later.

      crypto: ccp - Add hash state import and export support · 132e9068
      Tom Lendacky authored
      commit 952bce97 upstream.
      
      Commit 8996eafd ("crypto: ahash - ensure statesize is non-zero")
      added a check to prevent ahash algorithms from successfully registering
      if the import and export functions were not implemented. This prevents
      an oops in the hash_accept function of algif_hash. This commit causes
      the ccp-crypto module SHA support and AES CMAC support from successfully
      registering and causing the ccp-crypto module load to fail because the
      ahash import and export functions are not implemented.
      
      Update the CCP Crypto API support to provide import and export support
      for ahash algorithms.

      EDAC, amd64_edac: Shift wrapping issue in f1x_get_norm_dct_addr() · 1dcba551
      Dan Carpenter authored

      dct_sel_base_off is declared as a u64 but we're only using the lower 32
      bits because of a shift wrapping bug. This can possibly truncate the
      upper 16 bits of DctSelBaseOffset[47:26], causing us to misdecode the CS
      row.
