igmp should call consume_skb() for all correctly processed packets,
to avoid false dropwatch/drop_monitor false positives.

time: jiffies_delta_to_clock_t() helper to the rescue

2012-08-09T23:17:03+00:00

Various /proc/net files sometimes report crazy timer values, expressed
in clock_t units.

This happens when an expired timer delta (expires - jiffies) is passed
to jiffies_to_clock_t().

This function has an overflow in :

return div_u64((u64)x * TICK_NSEC, NSEC_PER_SEC / USER_HZ);

commit cbbc719fccdb8cb (time: Change jiffies_to_clock_t() argument type
to unsigned long) only got around the problem.

As we cant output negative values in /proc/net/tcp without breaking
various tools, I suggest adding a jiffies_delta_to_clock_t() wrapper
that caps the negative delta to a 0 value.

net: replace continue with break to reduce unnecessary loop in xxx_xmarksources

2012-04-05T09:42:18+00:00

The conditional which decides to skip inactive filters does not
change with the change of loop index, so it is unnecessary to
check them many times.

net: reintroduce missing rcu_assign_pointer() calls

2012-01-12T20:26:56+00:00

commit a9b3cd7f32 (rcu: convert uses of rcu_assign_pointer(x, NULL) to
RCU_INIT_POINTER) did a lot of incorrect changes, since it did a
complete conversion of rcu_assign_pointer(x, y) to RCU_INIT_POINTER(x,
y).

We miss needed barriers, even on x86, when y is not NULL.

igmp: Avoid zero delay when receiving odd mixture of IGMP queries

2012-01-09T22:06:46+00:00

Commit 5b7c84066733c5dfb0e4016d939757b38de189e4 ('ipv4: correct IGMP
behavior on v3 query during v2-compatibility mode') added yet another
case for query parsing, which can result in max_delay = 0.  Substitute
a value of 1, as in the usual v3 case.
