Subject: [PATCH] bgpd: Ensure FRR has enough data to read 2 bytes in
peek_for_as4_capability
In peek_for_as4_capability the code is checking that the
stream has at least 2 bytes to read ( the opt_type and the
opt_length ). However if BGP_OPEN_EXT_OPT_PARAMS_CAPABLE(peer)
is configured then FRR is reading 3 bytes. Which is not good
since the packet could be badly formated. Ensure that
FRR has the appropriate data length to read the data.

Subject: [PATCH] bgpd: Ensure that bgp open message stream has enough data to
read
If a operator receives an invalid packet that is of insufficient size
then it is possible for BGP to assert during reading of the packet
instead of gracefully resetting the connection with the peer.

Subject: [PATCH] bfdd: allow l3vrf bfd sessions without udp leaking
Until now, when in vrf-lite mode, the BFD implementation
creates a single UDP socket and relies on the following
sysctl value to 1:
echo 1 > /proc/sys/net/ipv4/udp_l3mdev_accept
With this setting, the incoming BFD packets from a given
vrf, would leak to the default vrf, and would match the
UDP socket.
The drawback of this solution is that udp packets received
on a given vrf may leak to an other vrf. This may be a
security concern.
The commit addresses this issue by avoiding this leak
mechanism. An UDP socket is created for each vrf, and each
socket uses new setsockopt option: SO_REUSEADDR + SO_REUSEPORT.
With this option, the incoming UDP packets are distributed on
the available sockets. The impact of those options with l3mdev
devices is unknown. It has been observed that this option is not
needed, until the default vrf sockets are created.
To ensure the BFD packets are correctly routed to the appropriate
socket, a BPF filter has been put in place and attached to the
sockets : SO_ATTACH_REUSEPORT_CBPF. This option adds a criterium
to force the packet to choose a given socket. If initial criteria
from the default distribution algorithm were not good, at least
two sockets would be available, and the CBPF would force the
selection to the same socket. This would come to the situation
where an incoming packet would be processed on a different vrf.
The bpf code is the following one:
struct sock_filter code[] = {
{ BPF_RET | BPF_K, 0, 0, 0 },
};
struct sock_fprog p = {
.len = sizeof(code)/sizeof(struct sock_filter),
.filter = code,
};
if (setsockopt(sd, SOL_SOCKET, SO_ATTACH_REUSEPORT_CBPF, &p, sizeof(p))) {
zlog_warn("unable to set SO_ATTACH_REUSEPORT_CBPF on socket: %s",
strerror(errno));
return -1;
}
Some tests have been done with by creating vrf contexts, and by using
the below vtysh configuration:
ip route 2.2.2.2/32 10.126.0.2
vrf vrf2
ip route 2.2.2.2/32 10.126.0.2

peer 2.2.2.2 multihop local-address 1.1.1.1 vrf vrf2

receive-interval 1500
!
The results showed no issue related to packets received by
the wrong vrf. Even changing the udp_l3mdev_accept flag to
1 did not change the test results.
