selftests: netfilter: add conntrack stress test
Add a new test case to check:
- conntrack_max limit is effective
- conntrack_max limit cannot be exceeded from within a netns
- resizing the hash table while packets are inflight works
- removal of all conntrack rules disables conntrack in netns
- conntrack tool dump (conntrack -L) returns expected number
of (unique) entries
- procfs interface - if available - has same number of entries
as conntrack -L dump
Expected output with selftest framework:
selftests: net/netfilter: conntrack_resize.sh
PASS: got 1 connections: netns conntrack_max is pernet bound
PASS: got 100 connections: netns conntrack_max is init_net bound
PASS: dump in netns had same entry count (-C 1778, -L 1778, -p 1778, /proc 0)
PASS: dump in netns had same entry count (-C 2000, -L 2000, -p 2000, /proc 0)
PASS: test parallel conntrack dumps
PASS: resize+flood
PASS: got 0 connections: conntrack disabled
PASS: got 1 connections: conntrack enabled
ok 1 selftests: net/netfilter: conntrack_resize.sh
