v2: - Use do_dump_opt in dump_socket to not call lookup_socket redundantly v3: - use getsockopt to check that unconnected socket has no peername and it's not listening - do test only socket protocol since family and type will be called in dump_one_inet_fd. v4: - Move proto tests to can_dump_inet_sk - Use SOL_TCP/TCP_INFO to gather info about tcp sockets v5: - hash unconnected sockets to run BUG_ON(already-dumped) logic - no default value for sk->wqlen, use zero from xzalloc - drop bogus xfree on error Signed-off-by:

Sometime we need sync points in testee program flow, for this reason task_waiter_ introduced. The call semantics is the following Parent Child ------ ----- task_waiter_init task_waiter_wait4 task_waiter_complete task_waiter_wait4 task_waiter_complete ... Thus initially task_waiter_init should be called to initialize all internals guts needed. Then one become waitee and calls for task_waiter_wait4, where lockid should be provided as an argument. Since it should be unique values the best option might be gettid(). The same applies to a waiter side -- it should call for task_waiter_complete and provide a lockid. Signed-off-by:

Strictly speaking we have to close all fds before reopening them from the image. This can be done using not yet merged nextfd syscall, but it's not yet merged :( By now just close std and 255 (bash's) descriptors. This is ugly, but I prefer to wait for the nextfd syscall. But skip the init tasks' stds becase the existing zdtm implementation uses system() in such tasks which doesn't work when all fds are closed. Signed-off-by:

Test with sysfs and proc as no other fs-s are currently supported. Will be fixed later. Note, that the original /proc mount is kept as the dumping code requires it for reading pagemap file with RSS info. Worth fixing it some day? Signed-off-by:

We need own proc for restoring mount namespace, since the proc should be umounted and mounted back diring namespace restore and I don't want to introduce a special kludge for this. One more notice -- the temp proc is mounted _after_ namespaces recreation for the same reason (it will be umounted by prepare_mnt_ns). Signed-off-by:

Namespace restore goes in two steps -- first, clean old mountpoints (except root) that are left after clone(CLONE_NEWNS) call. Next, repopulate the namespace with new mountpoints (except root) read from the image file. This patch adds the skeleton for the above -- reading the mountpoints from current proc and image and calling for mount/umount. The real action will come in further patches. Signed-off-by:

Build a tree of mountpoins that can be (u)mounted in a straight (forward or backward) order without EBUSY errors. The tree is built in two steps -- first create hierarchy based on mount iDs. Next -- resort siblings in the path depth order. Signed-off-by:

Encode it in u32 since we have to check filesystem name anyway (not everyone ie easily migratable). Dump _any_ root fs as we need the root entry on restore though do not mount it then -- it should be provided before crtools restore start. Signed-off-by:

On the restore path this structure will be used and it will be better to have them char * rather than char[64]. When scanning proc use the %ms specifier for this. Signed-off-by:

In olden times, when people didn't know how to write, they sent a courier with a letter. Now we can write messages from parasite, so SET_PARASITE_RET may be dropped. Signed-off-by:
Andrey Vagin <avagin@openvz.org> Looks good to me as well. Maybe we will refine messages to be able to identify where exactly parasite failed (say line). But it better to do in another patch. Acked-by:
