* SELinux: policy selectable handling of unknown classes and permsEric Paris2007-10-16
| | | | | | | | | | | | | | | | | | Allow policy to select, in much the same way as it selects MLS support, how the kernel should handle access decisions which contain either unknown classes or unknown permissions in known classes. The three choices for the policy flags are 0 - Deny unknown security access. (default) 2 - reject loading policy if it does not contain all definitions 4 - allow unknown security access The policy's choice is exported through 2 booleans in selinuxfs. /selinux/deny_unknown and /selinux/reject_unknown.

* SELinux: Improve read/write performanceYuichi Nakamura2007-10-16
| | | | | | | | | | | | | | It reduces the selinux overhead on read/write by only revalidating permissions in selinux_file_permission if the task or inode labels have changed or the policy has changed since the open-time check. A new LSM hook, security_dentry_open, is added to capture the necessary state at open time to allow this optimization.

* SELinux: tune avtab to reduce memory usageYuichi Nakamura2007-10-16
| | | | | | | | | | | | This patch reduces memory usage of SELinux by tuning avtab. Number of hash slots in avtab was 32768. Unused slots used memory when number of rules is fewer. This patch decides number of hash slots dynamically based on number of rules. (chain length)^2 is also printed out in avtab_hash_eval to see standard deviation of avtab hash table.

| * kbuild: introduce ccflags-y, asflags-y and ldflags-ySam Ravnborg2007-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce ccflags-y, asflags-y and ldflags-y so we soon can deprecate use of EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS. This patch does not touch any in-tree users - thats next round. Lets get this committed first and then fix the users of the soon to be deprecated variants next. The rationale behind this change is to introduce support for makefile fragments like: ccflags-$(CONFIG_WHATEVER_DEBUG) := -DDEBUG As a replacement for the uglier: ifeq ($(CONFIG_WHATEVER_DEBUG),y) EXTRA_CFLAGS := -DDEBUG endif Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

| * kbuild: check for wrong use of CFLAGSSam Ravnborg2007-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | External modules have in a few cases modifed gcc option by modifying CFLAGS. This has never been documented and was a bad practice. With the check to use KBUILD_CFLAGS it will no longer work so we better error out and tell what was wrong as a service to the external module users. This check can be overruled if KBUILD_NOPEDANTIC is set to something. Addid this possibility may allow older external module to build without any code modifications but potentially only loosing some un-important gcc options.

| * kconfig/menuconfig: distinguish between selected-by-another options and commentsMatej Laitl2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | menuconfig currently represents options implied by another option ('select' directive in Kconfig) by prefixing them with '---'. Unfortunately the same notation is used for comments. If the implied option is module capable, user can still switch between Y and M, all without any feedback until she visits option's help. (try saying M to MAC80211 and then toggling CFG80211) This patch changes notation of selected-by-another items by introducing 2 new representations for implied options: {*} or {M} for options selected by another modularized one, thus builtin or module capable, -*- or -M- for options that cannot be at the moment changed by user. The idea is to represent actual capability of the option by braces (dashes) around and to always report actual state by * or M inside.

| * kbuild: call make once for all targets when O=.. is usedMilton Miller2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the invocations of make in the output directory Makefile and the main Makefile for separate object trees to pass all goals to one $(MAKE) via a new phony target "sub-make" and the existing target _all. When compiling with separate object directories, a separate make is called in the context of another directory (from the output directory the main Makefile is called, the Makefile is then restarted with current directory set to the object tree). Before this patch, when multiple make command goals are specified, each target results in a separate make invocation. With make -j, these invocations may run in parallel, resulting in multiple commands running in the same directory clobbering each others results. I did not try to address make -j for mixed dot-config and no-dot-config targets. Because the order does matter, a solution was not obvious. Perhaps a simple check for MAKEFLAGS having -j and refusing to run would be appropriate. Signed-off-by: Milton Miller <miltonm@bga.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

| * kbuild: check if we can link gettext not just compileSam Ravnborg2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | cygwin provides the header file but the lib file needs to be added manually. A generic fix is to check if we can compile and link a program that uses gettext() and if it fails fall back to NO_NLS. International users of cygwin may have to specify HOST_LOADLIBES := "-lintl" on the make command line. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
| * kbuild: Use Elfnn_Half as replacement for Elfnn_SectionSam Ravnborg2007-10-12
| | | | | | | | | | | | | | | | The Elfnn_Section is not available on all platforms, noteworthy are cygwin. Use the safe replacement _Half. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

| | | | | | | | | | | | | | | | | | | | | | | | Extremly low values are of dubious usefulness anyway but in this case they actually were killing Qemu which simply wasn't able to complete mips_next_event() within 0x30 100MHz cycles even on fast hosts.

| * | [MIPS] Fix aliasing bug in copy_user_highpage, take 2.Ralf Baechle2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Turns out b868868ae0f7272228c95cc760338ffe35bb739d wasn't quite right. When called for a page that isn't marked dirty it would artificially create an alias instead of doing the obvious thing and access the page via KSEG0. The same issue also exists in copy_to_user_page and copy_from_user_page which was causing the machine to die under rare circumstances for example when running ps if the BUG_ON() assertion added by the earlier fix was getting triggered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | MIPSsim probably doesn't have any sort of environment, but writing a zero in it kills even the compiled in command line. This prevents booting via NFS root. Signed-Off-By: Thiemo Seufer <ths@networkno.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
