The first change (implicitly adding MNT_NODEV on remount) addresses a regression that was created when security issues with unprivileged remount were closed. I go on to update the remount test to make it easy to detect if this issue reoccurs. Then there are a handful of mount and umount related fixes. Then half of the changes deal with the a recently discovered design bug in the permission checks of gid_map. Unix since the beginning has allowed setting group permissions on files to less than the user and other permissions (aka ---rwx---rwx). As the unix permission checks stop as soon as a group matches, and setgroups allows setting groups that can not later be dropped, results in a situtation where it is possible to legitimately use a group to assign fewer privileges to a process. Which means dropping a group can increase a processes privileges. The fix I have adopted is that gid_map is now no longer writable without privilege unless the new file /proc/self/setgroups has been set to permanently disable setgroups. The bulk of user namespace using applications even the applications using applications using user namespaces without privilege remain unaffected by this change. Unfortunately this ix breaks a couple user space applications, that were relying on the problematic behavior (one of which was tools/selftests/mount/unprivileged-remount-test.c). To hopefully prevent needing a regression fix on top of my security fix I rounded folks who work with the container implementations mostly like to be affected and encouraged them to test the changes. > So far nothing broke on my libvirt-lxc test bed. :-) > Tested with openSUSE 13.2 and libvirt 1.2.9. > Tested-by: Richard Weinberger <richard@nod.at> > Tested on Fedora20 with libvirt 1.2.11, works fine. > Tested-by: Chen Hanxiao <chenhanxiao@cn.fujitsu.com> > Ok, thanks - yes, unprivileged lxc is working fine with your kernels. > Just to be sure I was testing the right thing I also tested using > my unprivileged nsexec testcases, and they failed on setgroup/setgid > as now expected, and succeeded there without your patches. > Tested-by: Serge Hallyn <serge.hallyn@ubuntu.com> > I tested this with Sandstorm.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This test shows the amount of memory used by the system. Note that this is dependent on the user-space that is loaded when this program runs. Optimally, this program would be run as the init program itself. The program is optimized for size itself, to avoid conflating its own execution with that of the system software. The code is compiled statically, with no stdlibs. On my x86_64 system, this results in a statically linked binary of less than 5K.

This is a light weight framework provides a set of interfaces to report test results. Tests can use these interfaces to report pass, and fail cases as well as when failure is due to configuration problems such as missing modules, or when a test that is should fail, fails as expected, and a test that should fail, passes. The framework uses POSIX standard return codes for reporting results to address the needs of users that want to run the kernel selftests from their user-space test suites and want to know why a test failed. In addition, the framework includes interfaces to use to report test statistics on number of tests passed and failed. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>

But if a test tries to undefine a default option, it is simply ignored and the default option stays as is. For example, if you want to have a test that defines no MIN_CONFIG then the test should be able to do that with: TEST_START MIN_CONFIG = Which should make MIN_CONFIG not defined for that test. But the way the code currently works, undefined options in tests are dropped. This is because the NULL options are evaluated during the reading of the config file and since one can disable default options in the default section with this method, it is evaluated there (the option turns to a undef). But undef options in the test section mean to use the default option. To fix this, keep the empty string in the option during the reading of the config file, and then evaluate it when running the test. This will allow tests to null out default options.

The assign_configs function now adds the config to the hash even if it is disabled, but changes the hash value to be that of the line "# CONFIG_FOO is not set". Unfortunately, the make_min_config test only checks to see if the config is removed. It now needs to check if the config is in the hash and not set to be disabled.
