When debugging it's useful to stop zdtm.py at certain points and check what's going on out there. For this the --sbs (step-by-step) option is introduced. It will make zdtm.py stop and wait for user keypress before dump, before restore and after restore. Signed-off-by:

Right now zdtm spawns test into a pseudo-container and redirects its output in a temp file. This is done not to mix outputs of tests, running in parallel, with each other. But if we run tests one by one or there's only one test in the list we can safely print the output right on the screen. Signed-off-by:

Currently we wait when a namespace will be restored to get its root. We need to open a namespace root to open a file to restore a memory mapping. A process restores mappings and only then forks children. So we can have a situation, when we need to open a file from a namespace, which will be "restored" by one of our children. The root task restores all mount namespaces and opens a file descriptor for each of them. In this patch we open root for each mntns in the root task. If we neeed to get root of a namespace which isn't populated, we can get it from the root task. After the CR_STATE_FORKING stage, the root task closes all namespace descriptors ane we know that all namespaces are populated at this moment. v2: don't close root_fd for root ns, because it was not opened Signed-off-by:

For historical reason we allocate the complete PATH_MAX here just to fetch a word of freezer state. Lets relax the stack pressue and rename @path to @state. Same time make states @frozen, @freezing, @thawed being static, we don't export them. Signed-off-by:

We need to perform dirty page tracking when dumping shmem but there we have only const vmas so we need pmc to work with them. Also pmc concept implies that it won't change its vmas so it would be natural to declared them as const. Signed-off-by:

CRIU doesn't save vaddr of each anon shmem page in anon shared mem pagemap img. It saves page offset from the beginning of anon shared memory area. CRIU calls page_xfer_dump_pages() with non zero @off argument to convert dumper virtual addresses to such offsets. The problem is in page_xfer_dump_pages() code. It substracts @off only for pages in pagemap but not for holes in pagemap. Bug is fixed in this patch. This patch is just a copy-paste of valid code path for pages to code path for holes. Bug is not currently reproduced in CRIU because: 1. Only anon shmem provides non-zero @off value to page_xfer_dump_pages() 2. Anon shared memory doesn't create holes in its pagemap (for now) This bugfix is a preparation for anon shared memory deduplication patchset. Signed-off-by:

Its only purpose if to verify that we can show up a huge number of inotify in fdoutput (before the kernel v3.18-rc1-7-ga3816ab we can show only handles which fit page size in summary). In particular we revealed that hald daemon makes up to 35 notification marks which kernel can't show up in a one pass and dump fails. Signed-off-by:

When __nonuserns_sysctl_op() hits non-existing it goes to the next iteration without updating 'req' pointer. Thus it continuously tries to open non-exitsting entry until breaking out of loop. We should go to the next sysctl instead. Fixes: f79f4546 ("sysctl: move sysctl calls to usernsd") Signed-off-by:

GCC now assumes by default that the stack is aligned to a 16-byte boundary. It's very unlikely that parasite head's first call will contain an SSE instruction which will segfault, but to be pedantically correct will lose additional 8 bytes.

Restore a receive queue in cases of: 1)socketpair with closed second end; 2)peer-less socket, who is a peer for others. We use here a hack, it is the connect() with AF_UNSPEC family, which clears peer of restoring socket. See unix_dgram_connect() for the details. This also makes socket_close_data test working. SOCK_STREAM is supported in TCP_ESTABLISHED case in the same function. Signed-off-by:
