For ZDTM purposes, poll.c uses delta of 5 seconds, which is fine, since tests don't take a very long time to pass. However, in vzt-cpt, we start a batch with multitude of tests and starting them all could take over an hour. Hence, the test is bound to fail. An easy solution would be to introduce an environment variable, which would allow to specify the delta - ZDTM_DELTA. If it's unset (which is default behaviour in ZDTM) - it would default to 5 seconds. However, if it's set (what we can do from vzt-cpt) - then it will use delta which is set by our test. travis-ci: success for test: add variable delta for poll.c test (rev2) Signed-off-by:

When splicing page server data from UNIX socket we may get error (EAGAIN) from splice if no data is available on the socket yet. This is because the SPLICE_F_NONBLOCK flag is checked by af_unix.c in the kernel to decide whether or not to do blocking read. This is not symmetrical with TCP sockets, which only check for the socket's O_NONBLOCK flag for the same decicion. Dropping the SPLICE_F_NONBLOCK flag is not possible too, as otherwise we'll block on the pipe when trying to put data into it. Even if part of the data fits into it kernel would block anyway untill full buffer is in. And there will be no read() from the pipe, as it should happen one step later in the same task. So to untie this, we need to wait for the data explicitly with poll(). Signed-off-by: -

A unix socket can be bound to itself, so we need only one socket instead of a pair of pipe. If we use a socket, we can peek a message and if it isn't for us we don't need to send it back. Currently a process reads message from pipe, if it isn't for him, it sends it back and sleeps for a random timeout. In a worst case each waiter will read and send a message back, before the right one will get it. travis-ci: success for series starting with [1/3] zdtm: call test_init() before doing anything Signed-off-by:

Test seem to assume that zdtm lib directory is on PATH, but if it's not - calling for parseargs.sh would fail (if cwd is static). Therefore, this patch changes this to ../lib/parseargs.sh which should be fine both for zdtm and vzt-cpt. travis-ci: success for test: fix shell script tests (conntracks & route_rules) Signed-off-by:

Compiling zdtm on the latest Fedora rawhide gives errors like this: ns.c: In function ‘prepare_mntns’: ns.c:122:13: error: In the GNU C Library, "makedev" is defined by <sys/sysmacros.h>. For historical compatibility, it is currently defined by <sys/types.h> as well, but we plan to remove this soon. To use "makedev", include <sys/sysmacros.h> directly. If you did not intend to use a system-defined macro "makedev", you should undefine it after including <sys/types.h>.

The PagemapEntry and struct iovec are quite interchangeable. PagemapEntry can be used directly in the few places that converted it to struct iovec.

Mike Rapoport authored
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.

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:

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:
