      vfs: fix up ENOIOCTLCMD error handling · 07d106d0
      Linus Torvalds authored
      We're doing some odd things there, which already messes up various users
      (see the net/socket.c code that this removes), and it was going to add
      yet more crud to the block layer because of the incorrect error code
      translation.
      
      ENOIOCTLCMD is not an error return that should be returned to user mode
      from the "ioctl()" system call, but it should *not* be translated as
      EINVAL ("Invalid argument").  It should be translated as ENOTTY
      ("Inappropriate ioctl for device").
      
      That EINVAL confusion has apparently so permeated some code that the
      block layer actually checks for it, which is sad.  We continue to do so
      for now, but add a big comment about how wrong that is, and we should
      remove it entirely eventually.  In the meantime, this tries to keep the
      changes localized to just the EINVAL -> ENOTTY fix, and removing code
      that makes it harder to do the right thing.

      mwifiex: fix crash during simultaneous scan and connect · b015dbc0
      Amitkumar Karwar authored
      If 'iw connect' command is fired when driver is already busy in
      serving 'iw scan' command, ssid specific scan operation for connect
      is skipped. In this case cmd wait queue handler gets called with no
      command in queue (i.e. adapter->cmd_queued = NULL).
      
      This patch adds a NULL check in mwifiex_wait_queue_complete()
      routine to fix crash observed during simultaneous scan and assoc
      operations.

      - point out active maintainers
      - pull the CAN driver discussion away from netdev ML
      - point to the new CAN web site on gitorious.org
      - add CAN development git repository URL to submit patches

      net: fsl: fec: fix build for mx23-only kernel · 0d903247
      Wolfram Sang authored
      If one only selects mx23-based boards, compile fails:
      
      drivers/net/ethernet/freescale/fec.c:410:2: error: 'FEC_HASH_TABLE_HIGH' undeclared (first use in this function)
      drivers/net/ethernet/freescale/fec.c:411:2: error: 'FEC_HASH_TABLE_LOW' undeclared (first use in this function)
      
      This is because fec.h uses CONFIG_SOC_IMX28 to determine the register
      layout of the core which makes sense since the MX23 does not have a fec.
      However, Kconfig uses the broader ARCH_MXS symbol and this way even
      makes the fec-driver default for MX23. Adapt Kconfig to use the more
      precise SOC_IMX28 as well.

      sch_qfq: fix overflow in qfq_update_start() · 6bafcac3
      Eric Dumazet authored
      grp->slot_shift is between 22 and 41, so using 32bit wide variables is
      probably a typo.
      
      This could explain QFQ hangs Dave reported to me, after 2^23 packets ?
      
      (23 = 64 - 41)
