      tcp: Fix bitmask test in tcp_syn_options() · b32d1310
      由 David S. Miller 提交于 
      As reported by Alexey Dobriyan:

	  CHECK   net/ipv4/tcp_output.c
	net/ipv4/tcp_output.c:475:7: warning: dubious: !x & y

And sparse is damn right!

	if (unlikely(!OPTION_TS & opts->options))
		    ^^^
		size += TCPOLEN_SACKPERM_ALIGNED;

OPTION_TS is (1 << 1), so condition will never trigger.

      udplite: Protection against coverage value wrap-around · 47112e25
      由 Gerrit Renker 提交于 
      This patch clamps the cscov setsockopt values to a maximum of 0xFFFF.

Setsockopt values greater than 0xffff can cause an unwanted
wrap-around.  Further, IPv6 jumbograms are not supported (RFC 3838,
3.5), so that values greater than 0xffff are not even useful.

Further changes: fixed a typo in the documentation.

      net: Print the module name as part of the watchdog message · 6579e57b
      由 Arjan van de Ven 提交于 
      As suggested by Dave:

This patch adds a function to get the driver name from a struct net_device,
and consequently uses this in the watchdog timeout handler to print as 
part of the message.

an array. Probably makes no actual code difference.

      This fixes the bridge reference count problem and cleanups ipv6 FIB
timer management.  Don't use expires field, because it is not a proper
way to test, instead use timer_pending().

      mac80211_hwsim.c: fix: BUG: unable to handle kernel NULL pointer dereference at 0000000000000370 · 3a33cc10
      由 Ian Schram 提交于 
      I was looking at this out of interest, but I'm in no way familiar with
the code.

Looks to me that the error handling code in mac80211_hwsim is awkward.
Which leads to it calling ieee80211_unregister_hw even when
ieee80211_register_hw failed.

The function has a for loop where it generates all simulated radios.
when something fails, the error handling will call mac80211_hwsim_free
which frees all simulated radios who's pointer isn't zero. However the
information stored is insufficient to determine whether or not the call
to ieee80211_register_hw succeeded or not for a specific radio. The
included patch makes init_mac80211_hwsim clean up the current simulated
radio, and then calls into mac80211_hwsim_free to clean up all the
radios that did succeed.

This however doesn't explain why the rate control registration failed..
build tested this, but had some problems reproducing the original
problem.

      netfilter: nf_nat_sip: c= is optional for session · c71529e4
      由 Herbert Xu 提交于 
      According to RFC2327, the connection information is optional
in the session description since it can be specified in the
media description instead.

My provider does exactly that and does not provide any connection
information in the session description.  As a result the new
kernel drops all invite responses.

This patch makes it optional as documented.
