PAGE_SIZE allocations via slab are not guaranteed to be page-aligned;
use get_zeroed_page for the 'pt' buffer (I don't really know what this
is, only that it is passed to firmware and that the first error
message complains about its alignment). This allows the system to

There is no need to synchronize the polling with the transmit

no need to wait for it to finish.

atif is tested for being NULL twice, with the same effect in each case. I
have kept the second test, as it seems to fit well with the comment above it.

See commit 1045b03e07 ("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.

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.
