Since commit 95009c4c6d5 (criu: pagemap: introduce advance() helper for pagemap iteration) seek_pagemap_page traverses the entire pagemap, rather than starts each time from the last pagemap that was used. With large pagemaps (like, e.g. in maps05 case) the new behavior causes exponential increase in amount of calls to skip_pagemap_page for every new snapshot. Let's restore the original behavior. Fixes: #217 Reported-by:

By default, sockets03 doesn't set SIGPIPE handler to SIG_IGN. When run by zdtm.py, it doesn't cause problem, because it inherits signal handler. However, when run via vzt-cpt (which uses system() to launch tests), it receives default handler (which would terminate test). As result, test is guaranteed to fail, because it will attempt to write to shutdown receiver and get SIGPIPE in the face. travis-ci: success for test: Fix sockets03 default SIGPIPE handler not being set to IGN (rev2) Acked-by:

Check that SO_PEERCRED socket options restored correctly. Now it's not supported, thus test is marked as "noauto". (It seems support of this feature will require "ghost tasks", when we introduce them). travis-ci: success for zdtm: Add sock_peercred test Signed-off-by:

Now we remove a link_remap file when all its files are restored. It is wrong, because something else may fail and we will not be able to repeat an attempt to restore processes again. travis-ci: success for files: remove link_remaps when everything has been restored Signed-off-by:

link-remap files has to be deleted only if processes have been restored successfully. Otherwise we can want to repeat an attempt, but it is imposible if some link-remap files were deleted. Signed-off-by:

DESTDIR is mostly used by packagers (such as from rpm spec or deb rules), or just to try installation, and normally should be left unset/empty. Setting it to / looks weird to me. Besides, by leaving it empty we are making sure everything works if DESTDIR is not set. Fix INSTALL.md accordingly. travis-ci: success for Makefile.install: DESTDIR should be empty CC: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by:

Use alias function attribute to provide memcpy(), memcmp() and memset() in case we're not linking with libc. This is needed as compiler can generate calls to those functions (clang actually does that).

Remove getting opts from descriptors out from scm engine, this stuff is pure criu thing, so make it collect the data. The tricky change here is that parasite code needs memory to keep fd_opts on. The memory is taken from parasite args region, which is now bigger than it used to be. But that's not a big deal, as previously this space was allocated on the parasite stack (!, but with smaller chunks). On the other hand, now we have one memcpy less, as opts are put directly into the destination buffer. travis-ci: success for files: Rework send/recv-fds to be more generic Signed-off-by: -

Currently criu built with criu/pie-util-fd (which is a symlink to criu/pie/util-fd) with same flags as we use in general compel infection code. Moreover the criu link with libcompel.a, so we get a problem where send_fds/recv_fds are multiple defined. Lets rather unweave this mess: - drop criu/pie-util-fd.c completely - move send_fd/recv_fd inliners into scm.h Signed-off-by:
