No need to track in a weird way. It's small structure. Moreover, the rest of parasite code doesn't count for space allocated _after_ the main control block. We simply had happened to not hit any problems before. Signed-off-by: -

Introduce the fd_parms structure, that contains all we need to describe open fd during dump -- its name (int), pos, flags and id. The read_fd_parms routing fills one once and passes along the stack. This reduces the amount of arguments significantly. Signed-off-by:
-
Pavel Emelyanov authored
Make the dump_one_fd fn accept local fd and integer target fd values instead of target fd dir and target fd string name. This saves couple of atoi-s (done once) and makes the next patch simpler. Signed-off-by:

Pavel Emelyanov authored
This variable is actually a local fd, so reflect this in its name. Signed-off-by:

It was being done intentionally to be able to call close_cr_fdset several times in a row, bring this ability back. Otherwise I'm getting glibc complains about attemt to free already freed memory. Signed-off-by: -

In case if relative bind path found we skip such socket but forget to free previously allocated memory. Signed-off-by: -

We collect all unix sockets in the current net namespace, but a target process uses a few of them, so we may skip unsupported sockets and if it is used by a target process, lookup_socket returns error. Signed-off-by:

Path is not needed there -- we can call the get_image_path() in prep_cr_fdset_ routines and in parasite-syscall.c when required. Signed-off-by:

Remove unneeded path argument (we do know the file data is read from) and actually bogus show_header boolean. Also introduce two helpers for showing header and tail. Signed-off-by:
