      ipmi: Clear drvdata when interface is removed · 567eded9
      Takao Indoh authored
      This patch fixes a bug on hotmod removing.
      After ipmi interface is removed using hotmod, kernel panic occurs when
      rmmod impi_si.  For example, try this:
       # echo "remove,"`cat /proc/ipmi/0/params` > \
       # rmmod ipmi_si
      Then, rmmod fails with the following messages.
        ------------[ cut here ]------------
        WARNING: CPU: 12 PID: 10819 at /mnt/repos/linux/lib/list_debug.c:53 __list_del_entry+0x63/0xd0()
        CPU: 12 PID: 10819 Comm: rmmod Not tainted 3.17.0-rc1 #19
        Hardware name: FUJITSU-SV PRIMERGY BX920 S2/D3030, BIOS 080015 Rev.3D81.3030 02/10/2012
        Call Trace:
          cleanup_one_si+0x2a/0x230 [ipmi_si]

          cleanup_ipmi_si+0xbc/0xf0 [ipmi_si]
        ---[ end trace 70b4377268f85c23 ]---
      list_del in cleanup_one_si() fails because the smi_info is already
      removed when hotmod removing.
      When ipmi interface is removed by hotmod, smi_info is removed by
      cleanup_one_si(), but is is still set in drvdata.  Therefore when rmmod
      ipmi_si, ipmi_pnp_remove tries to remove it again and fails.
      By this patch, a pointer to smi_info in drvdata is cleared when hotmod
      removing so that it will be not accessed when rmmod.
      - Clear drvdata in cleanup_one_si
      - Change subject

      ipmi: work around gcc-4.9 build warning · cc4cbe90
      Arnd Bergmann authored
      Building ipmi on arm with gcc-4.9 results in this warning for an
      allmodconfig build:
        drivers/char/ipmi/ipmi_si_intf.c: In function 'ipmi_thread':
        include/linux/time.h:28:5: warning: 'busy_until.tv_sec' may be used uninitialized in this function [-Wmaybe-uninitialized]
          if (lhs->tv_sec > rhs->tv_sec)
        drivers/char/ipmi/ipmi_si_intf.c:1007:18: note: 'busy_until.tv_sec' was declared here
          struct timespec busy_until;
      The warning is bogus and this case can not occur.  Apparently this is a
      false positive resulting from gcc getting a little smarter about
      tracking assignments but not smart enough.
      Marking the ipmi_thread_busy_wait function as inline gives the gcc
      optimization logic enough information to figure out for itself that the
      case cannot happen, which gets rid of the warning without adding any
      fake initialization.

      Corey Minyard authored
      The code to send the channel config errors was missing an error report
      in one place and needed some more information in another, and had an
      extraneous bit of code.  Clean all that up.

      Pull networking fixes from David Miller:
       1) Don't halt the firmware in r8152 driver, from Hayes Wang.
       2) Handle full sized 802.1ad frames in bnx2 and tg3 drivers properly,
          from Vlad Yasevich.
       3) Don't sleep while holding tx_clean_lock in netxen driver, fix from
          Manish Chopra.
       4) Certain kinds of ipv6 routes can end up endlessly failing the route
          validation test, causing it to be re-looked up over and over again.
          This particularly kills input route caching in TCP sockets.  Fix
          from Hannes Frederic Sowa.
       5) netvsc_start_xmit() has a use-after-free access to skb->len, fix
          from K Y Srinivasan.
       6) Fix matching of inverted containers in ematch module, from Ignacy
       7) Aggregation of GRO frames via SKB ->frag_list for linear skbs isn't
          handled properly, regression fix from Eric Dumazet.
       8) Don't test return value of ipv4_neigh_lookup(), which returns an
          error pointer, against NULL.  From WANG Cong.
       9) Fix an old regression where we mistakenly allow a double add of the
          same tunnel.  Fixes from Steffen Klassert.
      10) macvtap device delete and open can run in parallel and corrupt lists
          etc., fix from Vlad Yasevich.
      11) Fix build error with IPV6=m NETFILTER_XT_TARGET_TPROXY=y, from Pablo
          Neira Ayuso.
      12) rhashtable_destroy() triggers lockdep splats, fix also from Pablo.
