radius: validate VRF names through Access-Accept and CoA

2026-09-07T19:08:04+00:00

Reject oversized and embedded-NUL VRF attributes and allocation failures. Keep explicit CoA lengths, restrict removal to literal 0, and bound the session API and shared interface lookup. Preserve default VRF removal. Adapted from Ritika Chopra's accel-ppp-ng PR #40, T8611, with the same validation boundary extended to the CoA path. Co-authored-by: Ritika Chopra

T55: add netlink buffer size configuration parameters

2021-12-20T15:00:32+00:00

Netlink buffers may overflow so it might be useful to increase send and receive netlink buffer sizes. Two parameters to [common] configuration section added: nl-rcv-buffer, nl-snd-buffer. It is required to set (sysctl) net.core.wmem_max>=nl-snd-buffer and net.core.rmem_max>=nl-rcv-buffer before running accel-pppd To check current netlink buffer size and related info use the following command: % ss -f netlink -m 0 0 rtnl:kernel * skmem:(r0,rb212992,t0,tb212992,f0,w0,o0,bl0,d0) 0 0 rtnl:-1140221812 * skmem:(r0,rb2048000,t0,tb80000,f0,w0,o0,bl0,d0) 0 0 rtnl:accel-pppd/14285 * skmem:(r0,rb2048000,t0,tb65536,f0,w0,o0,bl0,d0) ... (Please check man ss to get the meaning for r,rb,t,tb,f,w,o,bl and d params) In the ss output you will see the values doubled from configured. First accel-pppd netlink socket will use default values (rcv=1048576, snd=32768) regardless of configured nl-rcv-buffer and nl-snd-buffer values. Signed-off-by: Sergey V. Lobanov

net: new function get_ifindex

2020-03-18T08:07:38+00:00

The index of a given interface is an operation that highly depends on the network namespace we're in. This patch simply cuts out a function to get the index for a given interface name from the session initialization code, and expose it in the ap_net structure. This function can then be used to refresh the index when moving interfaces around. Signed-off-by: Simon Chopin

fix def_move_link

Do not know how this could work. It make more sense to move an interface from its original namespace not from its destination. Signed-off-by: François Cachereul

implemented support for network namespace

2016-07-11T06:47:04+00:00

This is done using radius attribute NAS-Port-Id. The new format of this attribute is NAS-Port-Id=[ns/][name]. Namespaces must be created malually by "ip netns add ..." command
