[CRIU] [PATCH v4 0/3] c/r non-dev net syctls

[Pavel Tikhomirov]

This is a try to migrate /proc/sys/net static sysctls -
the ones on netns but not per-device, now without dinamic
sysctls detection via /proc/sys/net readdir.

I added full path(except /proc/sys/ part) to sysctl entry in protobuf
as it is easier than hardcoding these entries in code.

/proc/sys/net/netfilter/nf_log/xx sysctls are hard to set - see
patch 2/4 so skiping NONE case. Made fix for kernel it is in nf-next:
http://git.kernel.org/cgit/linux/kernel/git/pablo/nf-next.git/commit/?id=c6ac37d8d8843fb1fdc34e4a2a41a4f027ab670c

Touching igmp_link_local_mcast_reports is unsafe in v4.3-v4.5 kernels
but as it is known kernel problem one can get fix easily see patch 1/3.

v2: remove non-writable in netns sysctls from test
v3: fix igmp_link_local_mcast_reports problem, add more sysctls from
kernel v4.6 to test
v4: remove readdir, make it static list, and unfix
igmp_link_local_mcast_reports

Pavel Tikhomirov (3):
  net/sysctl: c/r all except *.conf.* and *.neigh.*
  zdtm: add irand_range helper and use it in netns-dev test
  zdtm/sysctls: test all net.xxx except conf and neigh
