Better to stick with the convention we're trying to follow in general -- negative codes for error. Signed-off-by:

Linux kernel emulates anon-shared mappings by mapping internal tmpfs file in. We try to detect this by checking that the file under map is such, but do it with error -- major == 0 check is wrong, as regular tmpfs file can be such as well as btrfs or ecryptfs can screw things up. The only working way of doing this is to get the dev_t of this internal tmpfs mount. Signed-off-by: -

If the kernel is misconfigured (say UDP diag module is not set) we should detect such situation and report an error. This patch adds a test for error code. Note the kernel requires a patch as well. Without kernel patch this test do not harm anyway, thus safe to merge. #2412 Signed-off-by:

In case if the pr_err happens before pr_msg, the string buffer will have dangling timestamp prefix. Skip it here. Signed-off-by:

This is required to work with tcpdump. Signed-off-by: -

Three parts. Proc: open of map_files' link doesn't work on sockets. We fstatat it and check that it's a socket (it will be packet), then save the socket inode on vma_area. Dump: we resolve socket inode to socket id and save it on vma. We use id, not inode, since on restore we'll have to mmap some opened file, not just abstract socket with inode. Restore: when reading vma-s we just need to find out on what fd the respective packet socket is opened (i.e. -- no map-and-close sockets supported by now) and dup() it to let restorer mmap it back. All this make it possible to c/r the tcpdump tool! Signed-off-by: -

We can have a situation, when a socket is bound, but isn't listen yet. I can't find a situation, when we should not restore parameters. Signed-off-by:

One thing to note. The socket filter proggie is a set of struct-s wuth 8 and 16 bits values in it. Protobuf doesn't support such thing and it's too annoying to mess with yet another message for that. Instead, I encode all this stuff into array of fixed64 fields to handle endianity (yes, protobuf handles it, but each field is not just 64-bit value, but a structure). Signed-off-by: -

This test makes sure, that processes tree is restored before opened files. This is guaranteed by holding child's "/proc/<pid>/stat" file opened by parent. It was inspired by OpenVZ bug: #2404 IOW, OpenVZ can't restore container with such test inside. v2: 1) Test renamed + carefull cleanup + minor updates. Signed-off-by:
