      mld: respect RCU rules in ip6_mc_source() and ip6_mc_msfilter() · a9384a4c
      Eric Dumazet authored 
      Whenever RCU protected list replaces an object,
the pointer to the new object needs to be updated
_before_ the call to kfree_rcu() or call_rcu()

Also ip6_mc_msfilter() needs to update the pointer
before releasing the mc_lock mutex.

Note that linux-5.13 was supporting kfree_rcu(NULL, rcu),
so this fix does not need the conditional test I was
forced to use in the equivalent patch for IPv4.

Fixes: 882ba1f7 ("mld: convert ipv6_mc_socklist->sflist to RCU")

      net: igmp: respect RCU rules in ip_mc_source() and ip_mc_msfilter() · dba5bdd5
      Eric Dumazet authored 
      syzbot reported an UAF in ip_mc_sf_allow() [1]

Whenever RCU protected list replaces an object,
the pointer to the new object needs to be updated
_before_ the call to kfree_rcu() or call_rcu()

Because kfree_rcu(ptr, rcu) got support for NULL ptr
only recently in commit 12edff04 ("rcu: Make kfree_rcu()
ignore NULL pointers"), I chose to use the conditional
to make sure stable backports won't miss this detail.

if (psl)
    kfree_rcu(psl, rcu);

net/ipv6/mcast.c has similar issues, addressed in a separate patch.

      rxrpc: Enable IPv6 checksums on transport socket · 39cb9faa
      David Howells authored 
      AF_RXRPC doesn't currently enable IPv6 UDP Tx checksums on the transport
socket it opens and the checksums in the packets it generates end up 0.

It probably should also enable IPv6 UDP Rx checksums and IPv4 UDP
checksums.  The latter only seem to be applied if the socket family is
AF_INET and don't seem to apply if it's AF_INET6.  IPv4 packets from an
IPv6 socket seem to have checksums anyway.

What seems to have happened is that the inet_inv_convert_csum() call didn't
get converted to the appropriate udp_port_cfg parameters - and
udp_sock_create() disables checksums unless explicitly told not too.

Fix this by enabling the three udp_port_cfg checksum options.

      This patch limits the sniffing to only one port during the mirror add.
And during the mirror_del it checks for all the ports using the sniff,
if and only if no other ports are referring, sniffing is disabled.
The code is updated based on the review comments of LAN937x port mirror

      net: mdio: Fix ENOMEM return value in BCM6368 mux bus controller · e87f66b3
      Niels Dossche authored 
      Error values inside the probe function must be < 0. The ENOMEM return
value has the wrong sign: it is positive instead of negative.
Add a minus sign.

====================
selftests: net: add missing tests to Makefile

When generating the selftests to another folder, the fixed tests are
missing as they are not in Makefile. The missing tests are generated
by command:
$ for f in $(ls *.sh); do grep -q $f Makefile || echo $f; done
