A file pointed by an fd should be not unlinked and be open-able with the provided path (overmounts and/or renames coupled with links can screw it up). Signed-off-by: -

In case if no goals specified the all goal is implied so don't forget to generate deps. This as well fixes a problem where two "make clean" in a row forced build system to regenerate deps. Signed-off-by:

It was required before we switched to socketpair restore scheme. Now it's not required, sockets just connect to the peer they want to. Signed-off-by: -

No image copy occurs since 2b175282, so this fd can be hidden. Thus fixind the FIXME near it :) Signed-off-by:

Introduce and use generic file_desc ops for this. Signed-off-by: -

No need in per-type hash tables and search routines. We can handle it via generic file_desc structure. Some more thoughts on unixsk and pipe lists are still required :( Signed-off-by: -

This is a big change, yes. Dump unix sockets in the same manner as all the other files are done now. A few notes however. 1. We explicitly drop names for connected stream sockets. This is done to avoid conflicts with names -- accepted sockets share their names with the listening parent. This can be done later by binding a socket to a name, them renaming it to some temporary uniq one and at the very very end renaming some back to original. 2. Interconnected sockets are restored via socketpair() call. This is correct, but names are dropped. Need to bind() sockets after this (yes, this can be done), but for this we need to implement the trick with renames described before. 3. FD for socket queues is constantly re-opened not to resolve fd conflicts. Need to use service fds engine for this later. 4. Some code cleanup is still required, yes (will follow shortly).

A pipe buffer has 16 slots. A slot is page, offset and size. When we use splice and data is not aligned, splice connects a page from file cache and set offset. For this reason we loose a part of buffer. If a data size is more than 15 pages, data will be aligned in a image. Signed-off-by:

pipe_entry is encapsulated in pipe_info. All pipe_info-s connects in the list pipes. All pipe_info-s with the same piep_id connects to pipe_list, it a circular list without a defined head. Signed-off-by:

No need in separate per-type fn for doing this. We can just find the respective fd list and do sorting in the generic code. Signed-off-by: -

Since proc_parse.h declares functions which have list_head as arguments, it should include list.h and basic types. Otherwise if included into the files without list support the compilation might fail as | | In file included from cr-check.c:5: | ./include/proc_parse.h:83: error: expected declaration specifiers or ‘...’ before ‘bool’ Signed-off-by:
