This patch makes crtools to work with new /proc/pid/exe symlink restoration (the kernel part was reviewed by Oleg). So this patch is for new shiny kernel only (!), thus I suggest all developers to move on kernel crtools-3.3 (which can be found at usual place) and pick up this patch for crtools itself. (again, with this patch anything but crtools-3.3 will not work) Signed-off-by:

It happened some routines in parasite service code were not following calling convention so I fixed the callers and added a comment about adding new code here. At the same time the 3 error code madness is dropped as being requested by Pavel -- now we return one error code only. The PARASITE_ERR_ codes were dropped as well due to become redundant. The status of parasite service routine is set via SET_PARASITE_RET helper. In case if there is no error -- just return 0. The calling code should not expect to find anything sane in parasite_status_t because parasite code might not touch it at all. Same time, due to this convention the parasite's dump_socket_queue is getting rid of third @err member, because it's now returned as a regular error code. Signed-off-by:

Before this patch it may contain only a few megabytes. I think a real application may have a bigger mappings. Signed-off-by:

Using absolute paths for this is dangerous - while doing c/r we should be extremely carefully and not change tasks' roots and mount namespaces too early. Sometimes it will not work -- when restoring containers we'll be unable to switch to new CT and still have the ability to open images. Rework the images opening via openat and keep the image dir fd open all the time as the service fd (introduced earlier). Signed-off-by: -

These are the fds that help us to do c/r. We want them not to intersect with any "real-life" ones and thus store them close the the file rlimit boundary. For now only the logfd one is such. Signed-off-by: -

No need in checking the pid in every task loop cycle, just dump it at the beginning and that's it. Signed-off-by:

cr_dump_tasks does assign ret = -1 by default but dump_namespaces does shadow this variable with own error code so that if any subsequent calls will fail we will not notice the error. Signed-off-by:

There is a scenario when pstree_fd may be tried to close several times -- if we start crtools with "detach" option. So simply make restore_root_task to close opened file descriptor, this also simplifies the code. Signed-off-by:

There are three bugs in this code. 1. self vmas list is released before get-hint is called 2. get-hint code wrongly detects the hole (just bugs, no details) 3. exec hint is mapped without MAP_FIXED, but should Signed-off-by:

Reuse the TCP socket restore, just add connect() and sanity checks for protocol. This is OK, since UDP connect doesn't go to network for connection and (unlike unix sockets) doesn't require peer to be "online". It just puts the peer's creds on socket and returns. Signed-off-by:

Create two of them, bind both and connect one end to the other. Then check that send and sendto work and recv(from) receive proper message from proper address. Queues are expected to be dropped while test according to protocol constraints, thus all sends happen after restore. Signed-off-by:
