If the pagemap we read at some point covers two (or more) pagemaps in parent images, we cannot just call the parent page read for all those pages. Instead, we must call parent page read with shorter requests so that it handles its own pagemaps properly. Signed-off-by: -

When the VMA being restored is not COW-ed we read pages from images one-by-one which results in suboptimal pages.img access. Fix this by reading as many pages from iamge at once as possible withing the active pagemap and VMA. Signed-off-by: -

Implementing c/r of bridges with slaves shouldn't be too hard (viz. the comment), but this is all I need to for right now. v2: remove extra debug statement v3: * remember to close fd in dump_bridge * use "known" buffer length and snprintf for spath in dump_bridge * change brace style Signed-off-by:

In order to restore seccomp filters, we need to have access to dynamically allocated memory from the restorer blob, so we should unmap this memory afterwards. In order to do this, we need to suspend seccomp earlier, right after we attach to the tasks instead of just before we do the unmap of the restorer blob itself. Signed-off-by:

This reverts commit 73cb87f9. Two reasons: individual VMA-s may require different open flags and ghost and link-remap files should be properly unlinked at the end of open_path(). Need some more intelligent solution to this.

Commit a3a10c44 made all map_files opens happen with O_PATH for speed. However some files (sockets and aio rings) are not detected by this, since kernel's ->open callback is not called and we don't get the ENXIO code. Fix this by opening non-regular files with O_RDONLY. Signed-off-by:

When live migrating a container with large amount of processes inside the time to do page-server-ed dump may be up to 10 times slower than for the local dump. The delay is always introduced in the open_page_server_xfer() when criu negotiates the has_parent bit on the 2nd task. This likely happens because of the Nagel algo taking place -- after the write() of the OPEN2 command happened kernel delays this command sending waiting for more data. v2: Fix this by turning on CORK option on memory transfer sockets on send side, and NODELAY one once on urgent data. Receive side is always NODELAY-ed. According to Alexey Kuznetsov this is the best mode ever for such type of transfers. v3: Push packets in pre-dump's check_parent_server_xfer too. Signed-off-by:

On restore we do a sequence of open+mmap+close steps. On real apps there exists chains of private file mappings for the same file with different pgoffs and/or flags/prots. Signed-off-by: -

This descriptor is stat()-ed and used to dump file information. In both cases even read access is not required. Even if we decide to go dump ghost file out of it we'll re-open one with O_RDONLY. Signed-off-by:

These descriptors are purely used for openat()-s, so having them opened with O_PATH is OK and saves a little bit operations in the kernel space. Signed-off-by:
