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.

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:
|
||||
|
||||
ip route 2.2.2.2/32 10.126.0.2
|
||||
vrf vrf2
|
||||

||||

|
||||

|
||||

|
||||
ip address 10.126.0.1/24
|
||||

|
||||
line vty
|
||||

|
||||

|
||||

|
||||

||||

||||

||||

|
||||
transmit-interval 1500
|
||||
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.

Subject: [PATCH] lib: fix a crash in plist update
|
||||
|
||||
Problem:
|
||||
Prefix-list with mulitiple rules, an update to
|
||||
a rule/sequence with different prefix/prefixlen
|
||||
reset prefix-list next-base pointer to avoid
|
||||
having stale value.
|
||||
|
||||
In some case the old next-bast's reference leads
|
||||
to an assert in tri (trie_install_fn ) add.

Subject: [PATCH] lib: Routemap is not getting applied upon changing the
|
||||
routemap action
|
||||
|
||||
Description:
|
||||
This looks broken after NB changes in routemap. When routemap
|
||||
action modified from permit to deny, it is expected to apply
|
||||
the new action on the filtered routes before the action in the
|
||||
routemap data structure has been changed. But currently this is
|
||||
not handled by the corresponding northbound API.

message

If we send a crafted BGP UPDATE message without mandatory attributes, we do
|
||||
not check if the length of the path attributes is zero or not. We only check
|
||||
if attr->flag is at least set or not. Imagine we send only unknown transit
|
||||
attribute, then attr->flag is always 0. Also, this is true only if graceful-restart
|
||||
capability is received.

All other parsing functions done from bgp_nlri_parse() assume

no attributes == an implicit withdrawal. Let's move

bgp_nlri_parse_flowspec() into the same alignment.

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.
|
||||
|
||||
Fixes: #10404
