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 FRR has enough data to read 2 bytes in
|
||||||
|
bgp_open_option_parse
|
||||||
|
|
||||||
|
In bgp_open_option_parse 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 formateed. Ensure that
|
||||||
|
FRR has the appropriate data length to read the data.

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:
|
||||||
|
|
||||||
|

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.

Subject: [PATCH] zebra: Make netlink buffer reads resizeable when needed
|
|
||||||
|
|
||||||
Currently when the kernel sends netlink messages to FRR
|
|
||||||
the buffers to receive this data is of fixed length.
|
|
||||||
The kernel, with certain configurations, will send
|
|
||||||
netlink messages that are larger than this fixed length.
|
|
||||||
This leads to situations where, on startup, zebra gets
|
|
||||||
really confused about the state of the kernel. Effectively
|
|
||||||
the current algorithm is this:
|
|
||||||
|
|
||||||
read up to buffer in size
|
|
||||||
while (data to parse)
|
|
||||||
get netlink message header, look at size
|
|
||||||
parse if you can
|
|
||||||
|
|
||||||
The problem is that there is a 32k buffer we read.
|
|
||||||
We get the first message that is say 1k in size,
|
|
||||||
subtract that 1k to 31k left to parse. We then
|
|
||||||
get the next header and notice that the length
|
|
||||||
of the message is 33k. Which is obviously larger
|
|
||||||
than what we read in. FRR has no recover mechanism
|
|
||||||
nor is there a way to know, a priori, what the maximum
|
|
||||||
size the kernel will send us.
|
|
||||||
|
|
||||||
Modify FRR to look at the kernel message and see if the
|
|
||||||
buffer is large enough, if not, make it large enough to
|
|
||||||
read in the message.
|
|
||||||
|
|
||||||
This code has to be per netlink socket because of the usage
|
|
||||||
of pthreads. So add to `struct nlsock` the buffer and current
|
|
||||||
buffer length. Growing it as necessary.
|
|
