There is no need to synchronize the polling with the transmit function. The only place to synchronize is when we process the cq from the transmit function. Also removed spin_lock_irq, and using spin_trylock, if somebody else is already processing the cq, no need to wait for it to finish. Signed-off-by:

See commit 1045b03e ("netlink: fix overrun in attribute iteration") for a detailed explanation of why this patch is necessary. In short, nlmsg_next() can make "remaining" go negative, and the remaining >= sizeof(...) comparison will promote "remaining" to an unsigned type, which means that the expression will evaluate to true for negative numbers, even though it was not intended. I put "theoretical" in the title because I have no evidence that this can actually happen, but I suspect that a crafted netlink packet can trigger some badness. Note that the last test, which seemingly has the exact same problem (also true for nla_ok()), is perfectly OK, since we already know that remaining is positive. Signed-off-by:

Our TCP stack does not set the urgent flag if the urgent pointer does not fit in 16 bits, i.e., if it is more than 64K from the sequence number of a packet. This behaviour is different from the BSDs, and clearly contradicts the purpose of urgent mode, which is to send the notification (though not necessarily the associated data) as soon as possible. Our current behaviour may in fact delay the urgent notification indefinitely if the receiver window does not open up. Simply matching BSD however may break legacy applications which incorrectly rely on the out-of-band delivery of urgent data, and conversely the in-band delivery of non-urgent data. Alexey Kuznetsov suggested a safe solution of following BSD only if the urgent pointer itself has not yet been transmitted. This way we guarantee that when the remote end sees the packet with non-urgent data marked as urgent due to wrap-around we would have advanced the urgent pointer beyond, either to the actual urgent data or to an as-yet untransmitted packet. The only potential downside is that applications on the remote end may see multiple SIGURG notifications. However, this would occur anyway with other TCP stacks. More importantly, the outcome of such a duplicate notification is likely to be harmless since the signal itself does not carry any information other than the fact that we're in urgent mode.

If FWD-TSN chunk is received with bad stream ID, the sctp will not do the validity check, this may cause memory overflow when overwrite the TSN of the stream ID. The FORWARD-TSN chunk is like this: FORWARD-TSN chunk Type = 192 Flags = 0 Length = 172 NewTSN = 99 Stream = 10000 StreamSequence = 0xFFFF This patch fix this problem by discard the chunk if stream ID is not less than MIS.

While implementing a TCQ_F_THROTTLED flag there was used an smp_wmb() in qdisc_watchdog(), but since this flag is practically used only in sch_netem(), and since it's not even clear what reordering is avoided here (TCQ_F_THROTTLED vs. __QDISC_STATE_SCHED?) it seems the barrier could be safely removed.
