Merge branch 'tcp-take-a-bit-more-care-of-backlog-stress'

Eric Dumazet says:

====================
tcp: take a bit more care of backlog stress

While working on the SACK compression issue Jean-Louis Dupond
reported, we found that his linux box was suffering very hard
from tail drops on the socket backlog queue.

First patch hints the compiler about sack flows being the norm.

Second patch changes non-sack code in preparation of the ack
compression.

Third patch fixes tcp_space() to take backlog into account.

Fourth patch is attempting coalescing when a new packet must
be added to the backlog queue. Cooking bigger skbs helps
to keep backlog list smaller and speeds its handling when
user thread finally releases the socket lock.

v3: Neal/Yuchung feedback addressed :
Do not aggregate if any skb has URG bit set.
Do not aggregate if the skbs have different ECE/CWR bits

v2: added feedback from Neal : tcp: take care of compressed acks in tcp_add_reno_sack()
added : tcp: hint compiler about sack flows
added : tcp: make tcp_space() aware of socket backlog

tcp: implement coalescing on backlog queue

In case GRO is not as efficient as it should be or disabled,
we might have a user thread trapped in __release_sock() while
softirq handler flood packets up to the point we have to drop.

This patch balances work done from user thread and softirq,
to give more chances to __release_sock() to complete its work
before new packets are added the the backlog.

This also helps if we receive many ACK packets, since GRO
does not aggregate them.

This patch brings ~60% throughput increase on a receiver
without GRO, but the spectacular gain is really on
1000x release_sock() latency reduction I have measured.

Pull more y2038 work from Arnd Bergman:

y2038: convert more syscalls

Here is another set of system call changes to prepare the change over to
64-bit time_t. As before, the strategy is to change system calls that
take a 'struct timespec' argument over to 'struct __kernel_timespec',
which for now is defined to be the same but will get redefined to use a
64-bit time_t argument once we are ready to modify the system call tables.

The major change from previous patches is that the plan is no longer
to directly use the 'compat' system calls for providing compatibility
with the existing 32-bit time_t based entry points. Instead, we rename
the compat code to something that makes more sense on 32-bit architectures,
e.g. compat_timespec becomes old_timespec32.

With the renamed types in place, change over the 'stat' and 'utimes'
families of system calls, sched_rr_get_interval, recvmmsg and
rt_sigtimedwait. Another series for poll, select and io_pgetevents is
currently being tested.

====================
ip: Use rb trees for IP frag queue.

This patchset
* changes IPv4 defrag behavior to match that of IPv6: overlapping
fragments now cause the whole IP datagram to be discarded (suggested
by David Miller): there are no legitimate use cases for overlapping
fragments;
* changes IPv4 defrag queue from a list to a rb tree (suggested
by Eric Dumazet): this change removes a potential attach vector.

Upcoming patches will contain similar changes for IPv6 frag queue,
as well as a comprehensive IP defrag self-test (temporarily delayed).
