git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security Pull security subsystem updates for 3.4 from James Morris: "The main addition here is the new Yama security module from Kees Cook, which was discussed at the Linux Security Summit last year. Its purpose is to collect miscellaneous DAC security enhancements in one place. This also marks a departure in policy for LSM modules, which were previously limited to being standalone access control systems. Chromium OS is using Yama, and I believe there are plans for Ubuntu, at least. This patchset also includes maintenance updates for AppArmor, TOMOYO and others."

2012-03-08TTY: remove unneeded tty->index checksJiri Slaby
Checking if tty->index is in bounds is not needed. The tty has the index set in the initial open. This is done in get_tty_driver. And it can be only in interval <0,driver->num). So remove the tests which check exactly this interval. Some are left untouched as they check against the current backing device count. (Leaving apart that the check is racy in most of the cases.)

2012-01-18tpm: fix (ACPI S3) suspend regressionStefan Berger
This patch fixes an (ACPI S3) suspend regression introduced in commit 68d6e6713fcb ("tpm: Introduce function to poll for result of self test") and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers active. The suspend problem occurred if the TPM was disabled and/or deactivated and therefore the TPM_PCRRead checking the result of the (asynchronous) self test returned an error code which then caused the tpm_tis driver to become inactive and this then seemed to have negatively influenced the suspend support by the tpm_infineon driver... Besides that the tpm_tis drive may stay active even if the TPM is disabled and/or deactivated. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Tested-by: Rafael J.

2012-01-16random: Adjust the number of loops when initializingH. Peter Anvin
When we are initializing using arch_get_random_long() we only need to loop enough times to touch all the bytes in the buffer; using poolwords for that does twice the number of operations necessary on a 64-bit machine, since in the random number generator code "word" means 32 bits.

2012-01-16random: Use arch-specific RNG to initialize the entropy storeTheodore Ts'o
If there is an architecture-specific random number generator (such as RDRAND for Intel architectures), use it to initialize /dev/random's entropy stores. Even in the worst case, if RDRAND is something like AES(NSA_KEY, counter++), it won't hurt, and it will definitely help against any other adversaries.

2012-01-12Merge branch 'akpm' (aka "Andrew's patch-bomb, take two")Linus Torvalds
Andrew explains: - various misc stuff - Most of the rest of MM: memcg, threaded hugepages, others. - cpumask - kexec - kdump - some direct-io performance tweaking - radix-tree optimisations - new selftests code A note on this: often people will develop a new userspace-visible feature and will develop userspace code to exercise/test that feature. Then they merge the patch and the selftest code dies. Sometimes we paste it into the changelog. Sometimes the code gets thrown into Documentation/(!). This saddens me. So this patch creates a bare-bones framework which will henceforth allow me to ask people to include their test apps in the kernel tree so we can keep them alive. Then when people enhance or fix the feature, I can ask them to update the test app too. The infrastruture is terribly trivial at present - let's see how it evolves. - checkpoint/restart feature work. A note on this: this is a project by various mad Russians to perform c/r mainly from userspace, with various oddball helper code added into the kernel where the need is demonstrated. So rather than some large central lump of code, what we have is little bits and pieces popping up in various places which either expose something new or which permit something which is normally kernel-private to be modified. The overall project is an ongoing thing. I've judged that the size and scope of the thing means that we're more likely to be successful with it if we integrate the support into mainline piecemeal rather than allowing it all to develop out-of-tree. However I'm less confident than the developers that it will all eventually work! So what I'm asking them to do is to wrap each piece of new code inside CONFIG_CHECKPOINT_RESTORE. So if it all eventually comes to tears and the project as a whole fails, it should be a simple matter to go through and delete all trace of it. This lot pretty much wraps up the -rc1 merge for me. * akpm: (96 commits) unlzo: fix input buffer free ramoops: update parameters only after successful init ramoops: fix use of rounddown_pow_of_two() c/r: prctl: add PR_SET_MM codes to set up mm_struct entries c/r: procfs: add start_data, end_data, start_brk members to /proc/$pid/stat v4 c/r: introduce CHECKPOINT_RESTORE symbol selftests: new x86 breakpoints selftest selftests: new very basic kernel selftests directory radix_tree: take radix_tree_path off stack radix_tree: remove radix_tree_indirect_to_ptr() dio: optimize cache misses in the submission path vfs: cache request_queue in struct block_device fs/direct-io.c: calculate fs_count correctly in get_more_blocks() drivers/parport/parport_pc.c: fix warnings panic: don't print redundant backtraces on oops sysctl: add the kernel.ns_last_pid control kdump: add udev events for memory online/offline include/linux/crash_dump.h needs elf.h kdump: fix crash_kexec()/smp_send_stop() race in panic() kdump: crashk_res init check for /sys/kernel/kexec_crash_size ...

2011-12-29random: Use arch_get_random_int instead of cycle counter if availLinus Torvalds
We still don't use rdrand in /dev/random, which just seems stupid. We accept the *cycle*counter* as a random input, but we don't accept rdrand? That's just broken. Sure, people can do things in user space (write to /dev/random, use rdrand in addition to /dev/random themselves etc etc), but that *still* seems to be a particularly stupid reason for saying "we shouldn't bother to try to do better in /dev/random". And even if somebody really doesn't trust rdrand as a source of random bytes, it seems singularly stupid to trust the cycle counter *more*. So I'd suggest the attached patch. I'm not going to even bother arguing that we should add more bits to the entropy estimate, because that's not the point - I don't care if /dev/random fills up slowly or not, I think it's just stupid to not use the bits we can get from rdrand and mix them into the strong randomness pool.

2011-12-20ipmi_watchdog: restore settings when BMC resetCorey Minyard
If the BMC gets reset, it will return 0x80 response errors.
