These devices are injected into every network namespace when the ip_gre module is loaded. They cannot be configured as usable tunnels, so let's just ignore them. Signed-off-by:

In case of error inside collect_cgroups we need - @ctls list has been spliced into @cs->ctls so we cant just free it, but rather use put_ctls on @cs->ctls - delete @cs->l from global @cg_sets list before free it Signed-off-by:

If add_cgroup_properties failed we have @ncd sitting in @match->children or @current_controller->heads list, and then we free @ncd entry leaving those lists carrying dead pointers. Add proper rollback action. Signed-off-by:

Since we're freeing list entries don't forget to initialize list then, otherwise it gets out with free entries and may hit use-after-free bug. Signed-off-by:

We will still able to distinguish if it's garbage in ax register, but this is definitely prettier: (00.036900) 687 was trapped (00.036903) 687 is going to execute the syscall 158 (00.036928) 687 was trapped (00.036931) 687 is going to execute the syscall 173 Than that: (00.024403) 687 was trapped (00.024407) 687 is going to execute the syscall 9e (00.024419) 687 was trapped (00.024421) 687 is going to execute the syscall ad Signed-off-by:

Previously when we've been on early stage we tried to workaround lack of prlimit libc call simply providing own implementation, but it cause problems on some libc configurations so simply use rlimit64 and __NR_prlimit64 syscall directly. The kernel must support __NR_prlimit64 syscall and provide rlimit64 structure as well. Signed-off-by:

The option was in use when we didn't have the /proc/pid/ns links and thus ns ids. Later we used it at restore time to tell which namespaces to restore the pstree into. Right now ids are always generated and this option has no effect (and meaning). Signed-off-by: -

Description: 1)Create io context, submit several io operations and get events of some of them. 2)Sleep on signal. 3)Check tail, head and nr events restored correct. 4)Emit one more io operation. 5)Check tail has moved one number forward (i.e. synchronize in-kernel and userspace tails if they were different).

1)Dump/restore mmaped aio ring like any other private vma entry, with the only exception we do not predump it. 2)Create io context, set head and tail using write to /dev/null. 3)Copy aio ring restored in (1) to created in (2). 4)Remap (2) to address of (1). Signed-off-by:

The page server already knows how to create a TCP server and client. The code has been hidden behind static-s in page-xfer.c. This commit moves the common TCP server/client code to util.c to be able to also use it in the upcoming remote lazy-server/lazy-client userfaultfd enhanced criu. Signed-off-by:
