2017-04-08firmware: google memconsole: Remove useless submenu in KconfigThierry Escande1-4/+3
This patch removes the "Google Firmware Drivers" menu containing a menuconfig entry with the exact same name. The menuconfig is now directly under the "Firmware Drivers" entry.

2017-04-08ver_linux: Use /usr/bin/awk instead of /bin/awkSaul Wold1-1/+1
Most Linux distributions contain awk in /usr/bin by default, not in /bin. This script's suggested use is for creating version information for bug reporting. This has been tested on a number of different distributions, including Fedora, Ubuntu, OpenSUSE, Debian, Centos, Arch Linuxi, and Poky!

2017-04-08lkdtm: turn off kcov for lkdtm_rodata_do_nothing:Arnd Bergmann1-0/+2
I ran into a link error on ARM64 for lkdtm_rodata_do_nothing: drivers/misc/built-in.o: In function `lkdtm_rodata_do_nothing': :(.rodata+0x68c8): relocation truncated to fit: R_AARCH64_CALL26 against symbol `__sanitizer_cov_trace_pc' defined in .text section in kernel/built-in.o I did not analyze this further, but my theory is that we would need a trampoline to call __sanitizer_cov_trace_pc(), but the linker (correctly) only adds trampolines for callers in executable sections. Disabling KCOV for this one file avoids the build failure with no other practical downsides I can think of. The problem can only happen on kernels that contain both kcov and lkdtm, so if we want to backport this, it should be in the earliest version that has both (v4.8).

2017-04-08lkdtm: add bad USER_DS testKees Cook3-0/+13
This adds CORRUPT_USER_DS to check that the get_fs() test on syscall return (via __VERIFY_PRE_USERMODE_STATE) still sees USER_DS. Since trying to deal with values other than USER_DS and KERNEL_DS across all architectures in a safe way is not sensible, this sets KERNEL_DS, but since that could be extremely dangerous if the protection is not present, it also raises SIGKILL for current, so that no matter what, the process will die. A successful test will be visible with a BUG(), like all the other LKDTM tests. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2017-04-08nvmem: imx-ocotp: clear error bit after reading locked valuesRichard Leitner1-3/+38
When reading a "read locked" value from the OCOTP controller on i.MX6 SoC's an error bit is set. This bit has to be cleared by software before any new write, read or reload access can be issued. Therefore clear it after we detect such an "locked read".
