The function that does socket collecting is actually a rtnl request sending one. It will be usefull for netns dump/restore, so move it to generic place. Signed-off-by:

We need proc for restoring processes. The existent /proc may be not suitable. E.g. If processes are in pidns. crtools mounts procfs in a temporary directory, but it should be umounted at the end. Before this patch crtools did that, but it doesn't work if processes in a mount namespace. Actually this logic can be simplified and this patch does that. * create a tmp dir * mount procfs * open this directory and save a file descriptor. * detach procfs * remove the tmp dir * access to proc via openat, statat and so on.

When dumping a net namespace we'll have to create the transport socket in the target namespace. In order to do this we'll have to call setns swice -- before and after socket() call. I don't want to do it for every single task to dump, let's cache the socket instead. Signed-off-by: -

If we dump tasks with mntns, we should look at pathes from point of a mntns root. Now we support a situation when a root of an init task has the same root as the mntns root, because we have not another way to get a root of mntns. A path to an unix socket is copied, because the origin copy will be gone out from the function, where it was created. Signed-off-by:

Useful if one need a prefix over module messages. I use it in tty c/r, thus having something like | TTY: master 0x31 index 2 fd 6 pid 5079 (create 1) | TTY: `- slave 0x5c index 2 fd 255 pid 5080 (create 0 send 0) | TTY: standalone slave 0x2e index 1 fd 3 pid 5079 (create 1) in log. Which helps filtering messages. Signed-off-by:

The -Wno-unused-result option looks to have been introduced in GCC 4.5.0. So it's need turn off FORTIFY_SOURCE (compiler warn about unused results in fortification mode) instead of use -Wno-unused-result to avoid error in versions prior to 4.5.0. Signed-off-by:

It was accidentally broken by 424a4adb. It's better to use sk ino instead of sk id, since tcp connection may be unbound from any fds (not supported now) and thus there may be no ID for those. Signed-off-by:

This is a file with ... credits, yes :) While implementing the C/R stuff we've receive a LOT of help from various people and would like to mention them. If we've undeservedly forgotten someone (or something) -- please help us to make amends and send a patch to this file. Signed-off-by:
