While been playing with sockets dumping I found a case where we exit without descriptive error message. Fix it. Signed-off-by:

Only snd and rcv bufs and timeouts. Just as an example, others will be adder sequentially. Signed-off-by: -

Those sitting on the SOL_SOCKET level are common to different socket families and will be handled in a generic code. Signed-off-by: -

Since event polling depends on other files to be opened we split main files list into two parst -- event poll files and all other files, thus defer the creation of eventpoll files in prepare_fds(). Signed-off-by:

Now log messages may be splitted by pid Signed-off-by:
-
Andrey Vagin authored
If the option --log-pid is set, each process will have an own log file. Otherwise PID is added to each log message. A message can't be bigger than one page minus some bytes for pid. Signed-off-by:

It will fall through all the other checks, but let's do it explicitly for better code understanding. Signed-off-by: -

This saves some space on dynamic file_desc and makes file_desc_ops looks closer to fdinfo_ops used on dump. Signed-off-by: -
Pavel Emelyanov authored
No functional changes, just a code move. TODO: * need to write personal make_gen_id implementations for special files (device and pos is const for them effectively) * need to merge dump ops with restore ones (file_desc_ops) Signed-off-by: -

Now all the fds dump look very similar and we can reimplement it via indirect calls. Signed-off-by: -

Reg files are those obtained by open() syscall on restore. Pipes should be checked to belong to pipefs (fifos are not supported yet). Signed-off-by: -

At moment only open_mnt_root is there, which is needed for inotify restore. Signed-off-by:
-
Cyrill Gorcunov authored
To restore inotify we need to know the mount point device numbers, so this helper parses /proc/pid/mountinfo file for that. Signed-off-by:

v2: - Pass initial counter value to eventfd call (can't pass flags here since they are obtained with fcntl and must be restored same way or restore will fail) - Use rst_file_params for flags and owner restore - Use eventfd.[ch] instead of eventfs.[ch] - Move show funcs to eventfd.c Signed-off-by: -

This is also a code move plus two changes: * shmems renamed to dump_shmems * shmem area size is shared with restorer (it's one page for both for now) Signed-off-by: -

No changes, just code move (and rename of shmems variable). Signed-off-by: -

We use mincore to check which pages we should take with us into the image. The anonymour present or swapped should go, file present but not cow-ed should not. The mincore syscall wasn't very helpful with this -- it didn't detect swap, but did detect some non present pages (pagecache). Plus it didn't know anything about cow-ing filemaps. Andrey Morton suggested to use the pagemap file in proc, but it lacked the importaint stuff -- the cow filemap bit. Now it's there and we can switch to using it. The mincore usage for shared memory is still there, as for _that_ case it's correct. Signed-off-by: -

Dumped pages are those taken to the image Skipped pages are those, sitting in RAM, but left there (file shared pages) Total is the total amount of pages that fit into vmarea Signed-off-by: -
