This reverts commit 46c613cc. Andrey posted a proper fix for it. Moreover, the problem in first place was initiated by a parasite application running during test case, crtools knows nothing about. Signed-off-by:

It's perfectly fine to reuse descriptors here, since we use plain pipe() call and it migh choose the descriptor which we need after. Signed-off-by: -

Add the -l option to show the list of tests Make the default zdtm/live/ prefix when running individual test Now you can do it like # sh ./zdtm.sh for running all tests # sh ./zdtm.sh -l to list available tests # sh ./zdtm.sh <test> to run test <test>, e.g. "static/pipe00" Signed-off-by:

This makes crtools correctly abort when working on wrong kernel. Otherwise all the open files will have the same (garbage) ID and the subsequent restore will result in broken app. Signed-off-by:

The old code carried the path through the stack. Now we have pstree_pid and handy helpers to get one. Tested by pipes00 test from zdtm (it forks). Signed-off-by:

And do not use strcpy, better to stick with strncpy. Moreover, to be on a safe side make proc internal buffer big enough even for "(%16s)" format, it's hardly possible that the kernel ever change stat format but just to be on a safe side. Signed-off-by: -

Instead of passing self-vma file path to restorer code simply open it before restore_task call and pass descriptor instead. This saves some memory. Signed-off-by:

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:
