Title:
ipv4: enable route flushing in network namespaces
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Disco:
Fix Committed
Bug description:
SRU Justification
Impact: Tools such as vpnc try to flush routes when run inside network
namespaces by writing 1 into /proc/sys/net/ipv4/route/flush. This
currently does not work because flush is not enabled in non-initial network
namespaces. Users have complained about this at various times (cf. Link:
https://github.com/lxc/lxd/issues/4257).
Fix: Enable /proc/sys/net/ipv4/route/flush inside non-initial network
namespaces.
Regression Potential: None, since this didn't use to work before.
Since routes are per network namespace it is safe to enable
/proc/sys/net/ipv4/route/flush in there.
Test Case: Tested with LXD on a kernel with the patch applied and by
running vpnc successfully.
Target Kernels: All LTS kernels starting from 4.15. Kernel 5.3 has the
patchset upstream.
