make: config -- Drop try-build helper Don't need it, also add DEFINES into try-cc, after all we define a number of things in this variable and it's better to pass it to tests for conditional compilation.

lsm: add support for c/ring LSM profiles This patch adds support for checkpoint and restore of two linux security modules (apparmor and selinux). The actual checkpoint or restore code isn't that interesting, other than that we have to do the LSM restore in the restorer blob since it may block any number of things that we want to do as part of the restore process. I tried originally to get this to work using libraries in the restorer blob, but I could _not_ get things to work correctly (I assume I was doing something wrong with all the static linking, you can see my draft attempts here: https://github.com/tych0/criu/commits/apparmor-using-libraries ). I can try to resurrect this if it makes more sense, to do it that way, though. v2: lsm_profile lives in creds.proto instead of the task core, look in a more canonical place for selinuxfs and don't try to special case any selinux profile names. v3: only allow unconfined selinux profiles Signed-off-by: Tycho Andersen <tycho.andersen@canonical.com> Signed-off-by: Pavel Emelyanov <xemul@parallels.com> 2015-05-06 16:18:42 -06:00
