* unshare,nsenter: Move the old libc handling into a common header namespace.hEric W. Biederman2013-01-172-55/+2Star
| | | | | | | | | | | | | | Move the defitions of CLONE_NEWNS, CLONE_NEWUTS, CLONE_NEWIPC, CLONE_NEWNET, CLONE_NEWUSER, CLONE_NEWPID into namespace.h in case sched.h does not provide those definitions. Are there systems around that are old enough that still need this? Move the definitions of unshare() and setns() into namespace.h for supporting old versions of libc that does not provice these. I have tested this support with setns as I still have systems old enough that glibc does not wrap setns. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>

* nsenter: Enhance waiting for a child processEric W. Biederman2013-01-171-13/+35
| | | | | | | | | | | | | | | | | | | | | | In the case of a pid namespace we need to fork a child process instead of calling exec. Move all of that logic out of line into a function continue_as_child, making the logic of the primary case easier to understand. Update the logic for waiting for a child process to suspend ourselves when the child processes suspends and to continue the child process when we are unsuspsended. This supports the bash suspend command and various editors that suspend themselves. If the child process exits with a signal update the logic to run kill(getpid(), WTERMSIG(status)) so the caller sees the same exit code that nsenter observed. There will always be permission to send signals to our children and the tty is not changing so there is no need for the intermediate process to forward signals to it's child. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
* unshare: Add support for the pid and user namespacesEric W. Biederman2013-01-172-13/+33
| | | | | | | | | | | | - Update the unshare application to support the pid and user namespaces. - Update the man page for the new options - Fix typo in the man page where UTS was spelled UTC. - Remove the vestigal support for running a suid unshare. After unsharing a user namespace setuid(getuid()) won't work because no uid or gid mappings have been specified yet. So it is just easier not to have any support for running suid.

* nsenter: new command (light wrapper around setns)Eric W. Biederman2013-01-173-0/+394
| | | | | | | | | | | Inspired by unshare, nsenter is a simple wrapper around setns that allows running a new process in the context of an existing process. Full paths may be specified to the namespace arguments so that namespace file descriptors may be used wherever they reside in the filesystem. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>

* mount: Fix -t in listing mode when run as non-rootRichard Tollerton2013-01-091-1/+6
| | | | | | | | | | | Presently, libmount-mount completely prohibits the use of -t by non-root users. This breaks using -t in listing mode as a user, which represents a regression against mount-deprecated, macosx and presumably *BSD. This commit fixes the issue by deferring the mnt_context_is_restricted check for -t until we know we're not in listing mode. Signed-off-by: Rich Tollerton <rich.tollerton@ni.com>

* unshare: support the switching of namespacesNeil Horman2013-01-073-29/+83
| | | | | | | | | | | | | | | | | | | | | In addition to the unshare syscall, there exists the setns syscall, which allows processes to migrate to the namepsaces of other processes. Add this functionality into the unshare command, as they operate in a fairly simmilar fashion. Note: There was discussion of adding a path based namespace argument to unshare in the origional discussion thread, but I opted to leave that out as it didn't seem to fit in nicely with the current argument pattern. I figure we can always add that in later if we need to [kzak@redhat.com: - fix optional arguments - do not call unshare if no flag specified - use O_CLOEXEC - codding style cleanup] Signed-off-by: Neil Horman <nhorman@tuxdriver.com> CC: Karel Zak <kzak@redhat.com> Signed-off-by: Karel Zak <kzak@redhat.com>
