It turns out DCCP calls __sk_receive_skb(), and this broke when
lookups no longer took a reference on listeners.

Fix this issue by adding a @refcounted parameter to __sk_receive_skb(),
so that sock_put() is used only when needed.

      tcp: fix return value for partial writes · 79d8665b
      Eric Dumazet authored 
      After my commit, tcp_sendmsg() might restart its loop after
processing socket backlog.

If sk_err is set, we blindly return an error, even though we
copied data to user space before.

We should instead return number of bytes that could be copied,
otherwise user space might resend data and corrupt the stream.

This might happen if another thread is using recvmsg(MSG_ERRQUEUE)
to process timestamps.

Issue was diagnosed by Soheil and Willem, big kudos to them !

      ipv4: allow local fragmentation in ip_finish_output_gso() · 9ee6c5dc
      Lance Richardson authored 
      Some configurations (e.g. geneve interface with default
MTU of 1500 over an ethernet interface with 1500 MTU) result
in the transmission of packets that exceed the configured MTU.
While this should be considered to be a "bad" configuration,
it is still allowed and should not result in the sending
of packets that exceed the configured MTU.

Fix by dropping the assumption in ip_finish_output_gso() that
locally originated gso packets will never need fragmentation.
Basic testing using iperf (observing CPU usage and bandwidth)
have shown no measurable performance impact for traffic not
requiring fragmentation.

      Imagine initial value of max_skb_frags is 17, and last
skb in write queue has 15 frags.

Then max_skb_frags is lowered to 14 or smaller value.

tcp_sendmsg() will then be allowed to add additional page frags
and eventually go past MAX_SKB_FRAGS, overflowing struct
skb_shared_info.

      qede: Correctly map aggregation replacement pages · 9512925a
      Mintz, Yuval authored 
      Driver allocates replacement buffers before-hand to make
sure whenever an aggregation begins there would be a replacement
for the Rx buffers, as we can't release the buffer until
aggregation is terminated and driver logic assumes the Rx rings
are always full.

For every other Rx page that's being allocated [I.e., regular]
the page is being completely mapped while for the replacement
buffers only the first portion of the page is being mapped.
This means that:
  a. Once replacement buffer replenishes the regular Rx ring,
assuming there's more than a single packet on page we'd post unmapped
memory toward HW [assuming mapping is actually done in granularity
smaller than page].
  b. Unmaps are being done for the entire page, which is incorrect.

Unlike commit 26cabd31
("sched, net: Clean up sk_wait_event() vs. might_sleep()"), the
sleeping function is called before schedule_timeout(), this is indeed
a bug. Fix this by moving the wait logic to the new API, it is similar
to commit ff960a73
("netdev, sched/wait: Fix sleeping inside wait event").

      geneve: avoid using stale geneve socket. · fceb9c3e
      pravin shelar authored 
      This patch is similar to earlier vxlan patch.
Geneve device close operation frees geneve socket. This
operation can race with geneve-xmit function which
dereferences geneve socket. Following patch uses RCU
mechanism to avoid this situation.
