2016-01-23build: container: Make 'unprivileged-user-namespace-supported?' more robust....* gnu/build/linux-container.scm (unprivileged-user-namespace-supported?): Only read and check the first character, to cope with a possible newline in the (pseudo-)file. Mark H Weaver
2015-11-03build: container: Add feature test predicates....* gnu/build/linux-container.scm (user-namespace-supported?, unprivileged-user-namespace-supported?, setgroups-supported?): New procedures. * tests/container.scm: Use predicates. * tests/syscalls.scm: Likewise. David Thompson
2015-10-28container: Remove unnecessary CLONE_CHILD_* flags....* gnu/build/linux-container.scm (namespaces->bit-mask): Remove CLONE_CHILD_CLEARTID and CLONE_CHILD_SETTID, which are unneeded. Discussed at <http://bugs.gnu.org/21694>. Ludovic Courtès
2015-10-10build: container: Fix call-with-clean-exit....Before, call-with-clean-exit would *always* return an exit code of 1. * gnu/build/linux-container.scm (call-with-clean-exit): Exit with status code of 0 if thunk does not throw an exception. * tests/containers.scm: Add test. David Thompson
2015-09-07build: container: Use the same clone flags as fork(3)....The intent is to make 'clone' behave a lot more like 'primitive-fork', which calls clone(2) with SIGCHLD, CLONE_CHILD_CLEARTID, and CLONE_CHILD_SETTID flags. Notably, running 'clone' at the REPL without these flags would break the REPL beyond repair. * guix/build/syscalls.scm (CLONE_CHILD_CLEARTID, CLONE_CHILD_SETTID): New variables. * gnu/build/linux-container.scm (namespaces->bit-mask): Add CLONE_CHILD_CLEARTID and CLONE_CHILD_SETTID to bit mask. David Thompson
2015-09-07build: container: Setup /dev/console....* gnu/build/linux-container.scm (mount-file-systems): Bind mount the controlling terminal as /dev/console. David Thompson
2015-08-08build: container: Add #:host-uids argument to call-with-container....It's not always possible to map 65536 uids when creating a container as the root user within another user namespace. This is true when building Guix within the build daemon's container. By using a uid range of 1 by default, even as the root user, the tests now pass. * gnu/build/linux-container.scm (initialize-user-namespace, run-container): Add 'host-uids' argument. (call-with-container): Add #:host-uids keyword argument. * tests/containers.scm ("container-excursion"): Update 'run-container' call. David Thompson
2015-07-09gnu: build: Add Linux container module....* gnu/build/linux-container.scm: New file. * gnu-system.am (GNU_SYSTEM_MODULES): Add it. * .dir-locals.el: Add Scheme indent rules for 'call-with-container', and 'container-excursion'. * tests/containers.scm: New file. * Makefile.am (SCM_TESTS): Add it.
