If shm->delta = MAX_DELTA and we set shm->stop to 1, the child can exit before the parent adds MAX_DELTA to shm->delta. parent child shm->stop = 1 if (shm->stop == 1 && shm->delta == MAX_DELTA) break shm->delta += MAX_DELTA Cc: Konstantin Neumoin <kneumoin@parallels.com> Reported-by:

This is the continuation -- check relevant userns features in criu check. Signed-off-by: -
Pavel Emelyanov authored
Right now we state that CRIU works on 3.11 and above kernels and, at the same time, have support for a couple of new features like aio, tun, timerfd etc. available in later kernels. Since these new features do not break generic operations we do not require them in the kernel strictly. However, in the zdtm tests it's very important to know exactly what can and what cannot be tested. Right now this is done in a tough manner -- if the kernel is not 3.11 or criu check fails for _any_ reason we treat the kernel as being "bad" and throw out a set of tests. I propose to test some individual features and form the list of tests in a more fine-grained manner. This patch only fixes the AIO, mnt_id, tun and posix-timers tests. Next I will add checks and fixes for user-namespaces tests. Signed-off-by:

There was a problem with diag modules, that were auto-loaded on dump and put some data into uevent sockets thus causing the dump to fail on that socket. The solution that time was to call modprobe in advance to make sure the diag modules are there. This turned out to be not nice solution as modprobe may fail if the module is missing and the requred functionality is built-in. To handle this for diag stuff it is mush faster and more reliable to ping the kernel with simple diag request and check that it reqched the required module. Signed-off-by: -

In the next patch we will need to care about the exact error reported by the kernel, so add the error callback for this. Signed-off-by: -

This patch reworks fixup_aufs_vma_fd() to let symbolic links in /proc/<pid>/map_files that are not pointing to AUFS branch names follow the non-AUFS applcation logic. The use case that prompted this commit was an application mapping /dev/zero as shared and writeable which shows up in map_files as: lrw------- ... 7fc5c5a5f000-7fc5c5a60000 -> /dev/zero (deleted) If the AUFS support code reads the link, it will have to strip off the " (deleted)" string added by the kernel but core CRIU code already does this.

Pavel reported that decimal values for some fields are hard to read, because people used to see hex values in there. Unfortunately, json doesn't support hex representation of integers, so we can only store them as hex strings. Not all field need to be represented as hex strings, so this set introduces a custom field option called "criu" to use in our proto files. One should use [(criu).hex = true] to mark which field should be represented as a hex string. pb2dict module from pycriu package will look into field options and if he finds that criu.hex is set to True, it will convert such field to/from hex string. Though, such behaviour is optional and user can request it by specifying --format hex when calling crit decode("crit encode" in its turn, detects such fields automatically and doesn't require any special cmdline options to be set). We need our proto files to compile with both protoc and protoc-c compilers, which requires creating google/protobuf directory with a symlink to /usr/include/google/protobuf/ descriptor.proto to make protoc-c and generated c files happy.

Currently we are handling conversion in the simplest way, by just parsing protobuf text format representation of pb message, splitting string in half and storing values wrapped in ""-s in python dict. Which leads to a bunch of errors, like, for example, when converting bytes fields. It also doesn't handle types properly. This patch introduces a proper way to handle pb<->json conversion by iterating through pb fields and properly storing them in dict or properly extracting values from dict. Signed-off-by:

pagemap.img is the special one, as it starts with an entry of pagemap_head type and is followed by entries of pagemap_entry type. Currently we treat pagemap as if pagemap_head is a payload and pagemap_entry's are an extra, which is wrong. Signed-off-by:

Before: { "magic" : "FOO", "entries" : [ { "payload" : { "foo" : "bar", "bar" : "foo" }, "extra" : "abc" }, { "payload" : { "foo" : "bar", "bar" : "foo" }, "extra" : "abc" } ] } After: { "magic" : "FOO", "entries" : [ { "foo" : "bar", "bar" : "foo" "extra" : "abc" }, { "foo" : "bar", "bar" : "foo" "extra" : "abc" } ] } We don't have any fields named "extra" in our pb msgs and it is not likely that we will ever have one, so there is no reason to worry about that.
