[CRIU] [PATCH 0/5] [RFC] netlink: dump and restore data from a receive queue

[Andrey Vagin]

From: Andrew Vagin <avagin at virtuozzo.com>

This series depends on kernel changes:
[PATH net-next 0/3] netlink: prepare to dump and restore data from a receive queue

It works only if a socket doesn't have a running callback. If a socket has a
running callback, it isn't enough to dump data from a receive queue, because
the callback will generate a new portion as soon as we read data from the
queue.

Andrew Vagin (5):
  check: check whether NETLINK_REPAIR is supported or not
  sk-queue: add an ability to dump addresses for messages
  netlink: request flags for netlink sockets
  netlink: restore data in a received queue for netlink sockets
  zdtm: add a new test to check netlink sockets with queued data
