Do it through new --weak-sysctls option to "criu restore". When we migrate from source with newer kernel with some modern sysctl to destination with older kernel without it or just with a kernel configured without it (e.g. no CONFIG_IPV6_ROUTER_PREF), we face a problem that not all of dumped sysctls can be successfuly restored on the destination. So to address these problem introduce weak sysctls migration, where we restore only available sysctls and skip others. https://github.com/xemul/criu/issues/248 While on it, fix workaround for stable_secret eio skip. travis-ci: success for Add ability to restore with missing sysctls on the target node Signed-off-by:

With the recent patches, criu is finally compileable with clang for all architectures. To keep it that way, we need Travis to test that on a regular basis. The downside is, Travis build time is increased about 2x. travis-ci: success for travis: enable arm/arm64/ppc builds with clang Signed-off-by:

Those two tests use same socket name and if both of them are run simultaneously, they would fight for socket and one will get EADDRINUSE.

The installation needs to use python2, but it uses python in the Makefile which fails later with syntax error (since it is written for python2). As per PEP-394 - https://www.python.org/dev/peps/pep-0394/ -, 'all distributions should ensure that python refers to the same target as python2 .', hence this change. Therefore, python2 is used by default in lib/Makefile, though this can be overriden with PYTHON_BIN. Tested with: a) PYTHON_BIN=python2 make install b) make install c) export PYTHON_BIN=python2 make test Signed-off-by: Raghavendra Prabhu <me at rdprabhu dot com> Signed-off-by:

Do not dump external sockets, that are not peers for some processes sockets. We do not use them on restore ==> we do not need to dump them. Signed-off-by:

Build in tests/others/rpc folder was failing due to the use of LDFLAGS variable instead of LDLIBS variable to link libprotobuf-c. The makefile uses implicit build rules. $(CC) $(LDFLAGS) n.o $(LOADLIBES) $(LDLIBS) Using LDFLAGS places -llibprotobuf-c before the object files, preventing the library from being searched for required functions. This commit changes the variable to LDLIBS instead to fix the issue. travis-ci: success for test/others/rpc: fix build error Signed-off-by:

We can MSG_PEEK those and can dump the files easily. The problem is in restore -- we need to first pass through all the fdinfo openings before sending the descriptors out, but by that time some sending sockets may have already closed :( So for now just detect SCM-s in queue and abort the dump, otherwise we'd just have them lost and the state spoiled. https://travis-ci.org/criupatchwork/criu/builds/177945936Signed-off-by:

Currently each page read request results in pread() call. But we can do better -- if there's no urgent need in data (which is likely the case for non-cow pagemaps) we can save where the date should go to and then read it in in one preadv syscall. For lazy pages we get an ability to do async read_pages call that would send the request to server and return w/o data in the buffer. The explicit sync() method is added since .close is void and nobody checks its return code. v2: Lost limits.h in pagemap.c for IOV_MAX (compilation). v3: split added code into smaller chunks https://travis-ci.org/criupatchwork/criu/builds/175451746Signed-off-by:

The 2nd big splitting patch -- move most of the code that is infect-related and doesn't know about criu internals (like protobuf) out of types.h headers. This is also big and fat patch, but it just moves the code around. Applies on top of sigframe extracting patch. Travis: https://travis-ci.org/xemul/criu/builds/171439595Signed-off-by:

There's a lot of code making sigframes for PIE spread all over the asm/restorer.h and arch/crtools.c. This patch collects it all into asm/sigframe.h and arch/sigframe.c for better modularity and for the sake of compel. The patch is huge, but it just moves the code around (making u32/u64 types conversions to uint32/64_t-s where appropriate). travis-ci: success for sigframe: Move sigframe-related code into sigframe.* Signed-off-by:

When C/R-ing a net namespace with --empty-ns net option we should also skip netfilter rules too (as per https://github.com/docker/docker/issues/27597). However, there's one thing to be handled -- local TCP blocking rules are expected to be there on restore by restore_iptables() which is no longer the case, so put them back manually. Test included, checked on zdtm/static/socket-tcpbuf-local :) v2: Full scripts for empty netns setup. https://github.com/xemul/criu/issues/246Signed-off-by:

So, this time we've mostly have a lot of code rework for compel. A big portion of it is still in criu-dev, but some has been merged into master. Other than this and a bunch of bugfixes -- .config file, support for Tun-Tap devices and deprecation of several CLI and RPC options by the --external one. Signed-off-by:

open_proc* and fopen_proc* are all macros, and they print errors in case something is wrong (and as they are macros they print correct file:line info, too). So, there is no need to print another error message right after calling those. This fixes double error messages like these: (00.047295) Error (criu/proc_parse.c:990): Can't open 18472/status on procfs: No such file or directory (00.047298) Error (criu/proc_parse.c:992): Can't open proc status: No such file or directory travis-ci: success for Assorted nitpicks Signed-off-by:
