2014-01-23autofs4: translate pids to the right namespace for the daemonMiklos Szeredi1-2/+14
The PID and the TGID of the process triggering the mount are sent to the daemon. Currently the global pid values are sent (ones valid in the initial pid namespace) but this is wrong if the autofs daemon itself is not running in the initial pid namespace. So send the pid values that are valid in the namespace of the autofs daemon. The namespace to use is taken from the oz_pgrp pid pointer, which was set at mount time to the mounting process' pid namespace. If the pid translation fails (the triggering process is in an unrelated pid namespace) then the automount fails with ENOENT.

2014-01-23autofs4: allow autofs to work outside the initial PID namespaceSukadev Bhattiprolu3-13/+43
Enable autofs4 to work in a "container". oz_pgrp is converted from pid_t to struct pid and this is stored at mount time based on the "pgrp=" option or if the option is missing then the current pgrp. The "pgrp=" option is interpreted in the PID namespace of the current process. This option is flawed in that it doesn't carry the namespace information, so it should be deprecated. AFAICS the autofs daemon always sends the current pgrp, which is the default anyway. The oz_pgrp is also set from the AUTOFS_DEV_IOCTL_SETPIPEFD_CMD ioctl. This ioctl sets oz_pgrp to the current pgrp. It is not allowed to change the pid namespace. oz_pgrp is used mainly to determine whether the process traversing the autofs mount tree is the autofs daemon itself or not. This function now compares the pid pointers instead of the pid_t values. One other use of oz_pgrp is in autofs4_show_options. There is shows the virtual pid number (i.e. the one that is valid inside the PID namespace of the calling process) For debugging printk convert oz_pgrp to the value in the initial pid namespace.

2014-01-23checkpatch: only flag FSF address, not gnu.org URLAlexander Duyck1-3/+1
This change restricts the check for the for the FSF address in the GPL copyright statement so that it only flags the address, not the references to the gnu.org/licenses URL which appears to be used in numerous drivers. The idea is to still allow some reference to an external copy of the GPL in the event that files are copied out of the kernel tree without the COPYING file. So for example this statement will still return an error: You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA. However, this statement will not return an error after this patch: You should have received a copy of the GNU General Public License along with this program.

2014-01-23checkpatch: attempt to find missing switch/case break;Joe Perches1-0/+25
switch case statements missing a break statement are an unfortunately common error. e.g.: commit 4a2c94c9b6c0 ("HID: kye: Add report fixup for Genius Manticore Keyboard") case blocks should end in a break/return/goto/continue. If a fall-through is used, it should have a comment showing that it is intentional. Ideally that comment should be something like: "/* fall-through */" Add a test to look for missing break statements. This looks only at the context lines before an inserted case so it's possible to have false positives when the context contains a close brace and the break is before the brace and not part of the patch context. Looking at recent patches, this is a pretty rare occurrence. The normal kernel style uses a break as the last line of the previous block.

To help avoid an architecture failing to correctly check kernel/user boundaries when handling copy_to_user, copy_from_user, put_user, or get_user, perform some simple tests and fail to load if any of them behave unexpectedly. Specifically, this is to make sure there is a way to notice if things like what was fixed in commit 8404663f81d2 ("ARM: 7527/1: uaccess: explicitly check __user pointer when !CPU_USE_DOMAINS") ever regresses again, for any architecture. Additionally, adds new "user" selftest target, which loads this module.

2014-01-23test: add minimal module for verification testingKees Cook3-0/+48
This is a pair of test modules I'd like to see in the tree. Instead of putting these in lkdtm, where I've been adding various tests that trigger crashes, these don't make sense there since they need to be either distinctly separate, or their pass/fail state don't need to crash the machine. These live in lib/ for now, along with a few other in-kernel test modules, and use the slightly more common "test_" naming convention, instead of "test-". We should likely standardize on the former: $ find . -name 'test_*.c' | grep -v /tools/ | wc -l 4 $ find . -name 'test-*.c' | grep -v /tools/ | wc -l 2 The first is entirely a no-op module, designed to allow simple testing of the module loading and verification interface. It's useful to have a module that has no other uses or dependencies so it can be reliably used for just testing module loading and verification. The second is a module that exercises the user memory access functions, in an effort to make sure that we can quickly catch any regressions in boundary checking (e.g. like what was recently fixed on ARM). This patch (of 2): When doing module loading verification tests (for example, with module signing, or LSM hooks), it is very handy to have a module that can be built on all systems under test, isn't auto-loaded at boot, and has no device or similar dependencies. This creates the "test_module.ko" module for that purpose, which only reports its load and unload to printk.

2014-01-23get_maintainer: add commit author information to --rolestatsJoe Perches1-6/+85
get_maintainer currently uses "Signed-off-by" style lines to find interested parties to send patches to when the MAINTAINERS file does not have a specific section entry with a matching file pattern. Add statistics for commit authors and lines added and deleted to the information provided by --rolestats. These statistics are also emitted whenever --rolestats and --git are selected even when there is a specified maintainer. This can have the effect of expanding the number of people that are shown as possible "maintainers" of a particular file because "authors", "added_lines", and "removed_lines" are also used as criterion for the --max-maintainers option separate from the "commit_signers". The first "--git-max-maintainers" values of each criterion are emitted. Any "ties" are not shown.

dma_addr_t's can be either u32 or u64 depending on a CONFIG option. There are a few hundred dma_addr_t's printed via either cast to unsigned long long, unsigned long or no cast at all. Add %pad to be able to emit them without the cast. Update Documentation/printk-formats.txt too.

2014-01-23printk/cache: mark printk_once test variable __read_mostlyJoe Perches3-11/+13
Add #include <linux/cache.h> to define __read_mostly. Convert cache.h to use uapi/linux/kernel.h instead of linux/kernel.h to avoid recursive #includes. Convert the ALIGN macro to __ALIGN_KERNEL. printk_once only sets the bool variable tested once so mark it __read_mostly. Neaten the alignment so it matches the rest of the pr_<level>_once #defines too.

2014-01-23dynamic_debug: add wildcard support to filter files/functions/modulesDu, Changbin1-5/+10
Add wildcard '*'(matches zero or more characters) and '?' (matches one character) support when qurying debug flags. Now we can open debug messages using keywords. eg: 1. open debug logs in all usb drivers echo "file drivers/usb/* +p" > <debugfs>/dynamic_debug/control 2. open debug logs for usb xhci code echo "file *xhci* +p" > <debugfs>/dynamic_debug/control Signed-off-by: Du, Changbin <[email protected]> Cc: Jason Baron <[email protected]> Cc: Joe Perches <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2014-01-23lib/parser.c: add match_wildcard() functionDu, Changbin2-0/+52
match_wildcard function is a simple implementation of wildcard matching algorithm. It only supports two usual wildcardes: '*' - matches zero or more characters '?' - matches one character This algorithm is safe since it is non-recursive.

2014-01-23uapi: convert u64 to __u64 in exported headersMike Frysinger2-2/+2
The u64 type is not defined in any exported kernel headers, so trying to use it will lead to build failures.

2014-01-23include/uapi/linux/dn.h: pull in ioctl.h headerMike Frysinger1-0/+1
This header uses _IOW/_IOR defines but doesn't include ioctl.h for it. If you try to use this w/out including ioctl.h yourself, it can fail to build, so add the explicit include.
