      mac80211: detect driver tx bugs · ef3a62d2
      Johannes Berg authored
      When a driver rejects a frame in it's ->tx() callback, it must also
      stop queues, otherwise mac80211 can go into a loop here. Detect this
      situation and abort the loop after five retries, warning about the
      driver bug.

      netlink: genl: fix circular locking · 6d1a3fb5
      Patrick McHardy authored
      genetlink has a circular locking dependency when dumping the registered
      families:
      
      - dump start:
      genl_rcv()            : take genl_mutex
      genl_rcv_msg()        : call netlink_dump_start() while holding genl_mutex
      netlink_dump_start(),
      netlink_dump()        : take nlk->cb_mutex
      ctrl_dumpfamily()     : try to detect this case and not take genl_mutex a
                              second time
      
      - dump continuance:
      netlink_rcv()         : call netlink_dump
      netlink_dump          : take nlk->cb_mutex
      ctrl_dumpfamily()     : take genl_mutex
      
      Register genl_lock as callback mutex with netlink to fix this. This slightly
      widens an already existing module unload race, the genl ops used during the
      dump might go away when the module is unloaded. Thomas Graf is working on a
      seperate fix for this.

      netdevice: Fix promiscuity and allmulti overflow · dad9b335
      Wang Chen authored
      Max of promiscuity and allmulti plus positive @inc can cause overflow.
      Fox example: when allmulti=0xFFFFFFFF, any caller give dev_set_allmulti() a
      positive @inc will cause allmulti be off.
      This is not what we want, though it's rare case.
      The fix is that only negative @inc will cause allmulti or promiscuity be off
      and when any caller makes the counters touch the roof, we return error.
      
      Change of v2:
      Change void function dev_set_promiscuity/allmulti to return int.
      So callers can get the overflow error.
      Caller's fix will be done later.
      
      Change of v3:
      1. Since we return error to caller, we don't need to print KERN_ERROR,
      KERN_WARNING is enough.
      2. In dev_set_promiscuity(), if __dev_set_promiscuity() failed, we
      return at once.
