TCP_CLOSE_WAIT remote side has shutdown and is waiting for us to finish writing our data and to shutdown (we have to close() to move on to LAST_ACK) TCP_LAST_ACK out side has shutdown after remote has shutdown.

soccr already knows how to restore this sockets. CRIU has to ...: * unlock all packets with the SOCCR_MARK mark * request half-closed socket via socket_diag * transpit src and dst addresses to libsoccr v2: remove SOCCR_FLAGS_ACKED_FIN travis-ci: success for series starting with [01/21] build: install libnet-dev Signed-off-by:

If a socket has been closed, it still has both addresses and we need to dump them. travis-ci: success for series starting with [01/21] build: install libnet-dev Signed-off-by:

For that we restore all sockets properties and then disable the repair mode before calling connect() and the kernel will sent a syn packet and move the socket into the sys-sent state. travis-ci: success for series starting with [01/21] build: install libnet-dev Signed-off-by:

A socket is in one of half-closed states, if it sent a fin packet or it received a fin packet. CRIU plays with fin packets to restore half-closed states too. When we need to sent a fin packet from a socket, we can call shutdown(SHUT_WR). When a fin packet has to be restore in a received queue, criu generate a fin packet and send it via a raw ip socket. A raw packet is sent with the SOCCR_MARK mark to be able to not block it. v2: remove the SOCCR_FLAGS_ACKED_FIN flag introduce sets of bits for different actions with fin packets travis-ci: success for series starting with [01/21] build: install libnet-dev Signed-off-by: -

We will need to disable the repair mode before connect() to restore syn-sent sockets.

These addresses will be used to restore half-closed sockets, we will need to send a fake fin packet for that. And in the next patch connect() will be moved into soccr. Signed-off-by:

We get sockets from task_diag, then we block network and dump sockets. A socket state can be changed between first two steps, so lets get a socket state on the third step and dump it. travis-ci: success for series starting with [01/21] build: install libnet-dev Signed-off-by:

Originally the repair mode could be enable only for sockets in closed and established states. Starting with the 4.10 kernel, it is possible to enable the repair mode for all connected sockets and now we can dump syn-sent and half closed sockets. travis-ci: success for series starting with [01/21] build: install libnet-dev Signed-off-by:

Made a symlink to CRIU's generated config.h, played with moving some code to soccr.h header. Changed types from u32 to uint32_t, otherwise we should include CRIU's "int.h" in soccr, but I'm lazy to add that.

As an API for dumping and restoring the data the structure with __u32-s is used. Getting one (and restoring) also involve the size of the structure so that both -- caller and library -- can know which "version" of it the other one is using. As a starting point all the fields that tcp_entry carries are used. Also note, that only tcp connection info is handled by the library. Stuff like addresses and ports, socket options and other are left for the caller to care for. Signed-off-by: -

For ZDTM purposes, poll.c uses delta of 5 seconds, which is fine, since tests don't take a very long time to pass. However, in vzt-cpt, we start a batch with multitude of tests and starting them all could take over an hour. Hence, the test is bound to fail. An easy solution would be to introduce an environment variable, which would allow to specify the delta - ZDTM_DELTA. If it's unset (which is default behaviour in ZDTM) - it would default to 5 seconds. However, if it's set (what we can do from vzt-cpt) - then it will use delta which is set by our test. travis-ci: success for test: add variable delta for poll.c test (rev2) Signed-off-by:
