2016-09-06lkdtm: adjust usercopy tests to bypass const checksKees Cook1-8/+17
The hardened usercopy is now consistently avoiding checks against const sizes, since we really only want to perform runtime bounds checking on lengths that weren't known at build time. To test the hardened usercopy code, we must force the length arguments to be seen as non-const. Signed-off-by: Kees Cook <keescook@chromium.org>
2016-08-02lkdtm: fix false positive warning from -Wmaybe-uninitializedKees Cook1-1/+1
The variable in use here doesn't matter (it's just used to exercise taking up stack space), but this changes its use to pass its address instead, to avoid a compiler warning: drivers/misc/lkdtm_usercopy.c:54:15: warning: 'bad_stack' may be used uninitialized in this function [-Wmaybe-uninitialized] Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Kees Cook <keescook@chromium.org>
2016-07-16lkdtm: silence warnings about function declarationsKees Cook1-3/+1
When building under W=1, the lack of lkdtm.h in lkdtm_usercopy.c and lkdtm_rodata.c was discovered. This fixes the issue and consolidates the common header and the pr_fmt macro for simplicity and regularity across each test source file. Signed-off-by: Kees Cook <keescook@chromium.org>
2016-07-07lkdtm: split usercopy tests to separate fileKees Cook1-0/+315
This splits the USERCOPY_* tests into the new lkdtm_usercopy.c file to help separate things better for readability. Signed-off-by: Kees Cook <keescook@chromium.org>
