With dependencies on a statically allocated full path name converted to
use %pOF format specifier, we can store just the basename of node, and
the unflattening of the FDT can be simplified.

This commit will affect the remaining users of full_name. After
analyzing these users, the remaining cases should only change some print
messages. The main users of full_name are providing a name for struct
resource. The resource names shouldn't be important other than providing
/proc/iomem names.

We no longer distinguish between pre and post 0x10 dtb formats as either
a full path or basename will work. However, less than 0x10 formats have
been broken since the conversion to use libfdt (and no one has cared).
The conversion of the unflattening code to be non-recursive also broke
pre 0x10 formats as the populate_node function would return 0 in that
case.

The driver doesn't support events from address families other than IPv4
and IPv6, so ignore them. Otherwise, we risk queueing a work item before
it's initialized.

This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES

IPMR family.

sctp_diag would not actually dump out sk/asoc if inet_sctp_diag_fill
returns err, in which case it shouldn't mark sk dumped by setting
cb->args[3] as 1 in sctp_sock_dump().

Otherwise, it could cause some asocs to have no parent's sk dumped
in 'ss --sctp'.

So this patch is to not set cb->args[3] when inet_sctp_diag_fill()
returns err in sctp_sock_dump().

Commit 86fdb344 ("sctp: ensure ep is not destroyed before doing the
dump") tried to fix an use-after-free issue by checking !sctp_sk(sk)->ep
with holding sock and sock lock.

But Paolo noticed that endpoint could be destroyed in sctp_rcv without
sock lock protection. It means the use-after-free issue still could be
triggered when sctp_rcv put and destroy ep after sctp_sock_dump checks
!ep, although it's pretty hard to reproduce.

I could reproduce it by mdelay in sctp_rcv while msleep in sctp_close
and sctp_sock_dump long time.

This patch is to add another param cb_done to sctp_for_each_transport
and dump ep->assocs with holding tsp after jumping out of transport's
traversal in it to avoid this issue.

It can also improve sctp diag dump to make it run faster, as no need
to save sk into cb->args[5] and keep calling sctp_for_each_transport
any more.

This patch is also to use int * instead of int for the pos argument
in sctp_for_each_transport, which could make postion increment only
in sctp_for_each_transport and no need to keep changing cb->args[2]
in sctp_sock_filter and sctp_sock_dump any more.

The default receive buffer size was reduced by recent change
to a value which was appropriate for 10G and Windows Server 2016.
But the value is too small for full performance with 40G on Azure.
Increase the default back to maximum supported by host.

liujian reported a problem in TCP_USER_TIMEOUT processing with a patch
in tcp_probe_timer() :
      https://www.spinics.net/lists/netdev/msg454496.html

After investigations, the root cause of the problem is that we update
skb->skb_mstamp of skbs in write queue, even if the attempt to send a
clone or copy of it failed. One reason being a routing problem.

This patch prevents this, solving liujian issue.

It also removes a potential RTT miscalculation, since
__tcp_retransmit_skb() is not OR-ing TCP_SKB_CB(skb)->sacked with
TCPCB_EVER_RETRANS if a failure happens, but skb->skb_mstamp has
been changed.

A future ACK would then lead to a very small RTT sample and min_rtt
would then be lowered to this too small value.

Tested:

rt_iif is only set to the actual egress device for the output path. The
recent change to consider the l3slave flag when returning IP_PKTINFO
works for local traffic (the correct device index is returned), but it
broke the more typical use case of packets received from a remote host
always returning the VRF index rather than the original ingress device.
Update the fixup to consider l3slave and rt_iif actually getting set.
