To include dgram bound && connected sockets, for example CR_FD_UNIXSK: /home/cyrill/crtools/unixsk-2813.img ---------------------------------------- fd 3 type 1 state 1 namelen 0 backlog 0 id 19505 peer 19506 fd 4 type 1 state 1 namelen 0 backlog 0 id 19506 peer 19505 fd 5 type 2 state 7 namelen 0 backlog 0 id 19507 peer 0 fd 6 type 2 state 7 namelen 18 backlog 18 id 19508 peer 0 --> test-socket-bound fd 7 type 2 state 7 namelen 0 backlog 0 id 19509 peer 19510 fd 8 type 2 state 7 namelen 17 backlog 17 id 19510 peer 0 --> test-socket-conn fd 9 type 2 state 7 namelen 23 backlog 23 id 19511 peer 19511 --> test-socket-bound-conn ---------------------------------------- The last one is bound and connected.

Restorer does really restore shared memory (including page contents restore) only on master process, while all other processes do open such memory area via map_files/ procfs entry so that we might have a situation when shared VMA is present in some particular core-%d.img file but it's not listed in collected shmems array and find_shmem_by_pid will return NULL. This is perfectly fine, be ready for that. Another issue is that shared memory might look like CR_FD_SHMEM: /home/cyrill/projects/kernel/crtools/shmem-2641.img ---------------------------------------- 0x7f2200775000-0x7f2200776000 id 19664 0x7f2200776000-0x7f2200777000 id 19663 ---------------------------------------- So vma area is [x;y) range and we should distinguish two shmem lookup cases - one when we search for page in shmem area - second when we lookup shmem area in collected ranges They both have a different lookup conditions so single find_shmem splitted into two helpers find_shmem and find_shmem_page as appropriate. This patch finally fixes the three process asynchronious shared memory updates test-case. Signed-off-by: -

In commit 99eb3d09 we started to use self-contained shared memory region but it revealed the problem that anonymous sgared mappings might be parsed by parse_maps incorrectly, so fix it and be ready to get anon-shared mappings. Signed-off-by:

Also make output a bit more fancy, as CR_FD_UNIXSK: unixsk-2440.img ---------------------------------------- fd 3 type 1 state 1 namelen 0 id 19406 peer 19407 fd 4 type 1 state 1 namelen 0 id 19407 peer 19406 fd 5 type 2 state 7 namelen 7 id 19408 peer 0 ---> [tst-sk] fd 6 type 2 state 7 namelen 0 id 19409 peer 0 fd 7 type 2 state 7 namelen 0 id 19410 peer 19411 fd 8 type 2 state 7 namelen 8 id 19411 peer 0 ---> [tst-sk1] ---------------------------------------- Signed-off-by: -
