However, this warning is overly pessimistic, in that # it is only happy with stack array sizes that are declared as constant # expressions, and not constant values. One case of this is the # evaluation of the max() macro which, due to its construction, ends up # converting constant expression arguments into a constant value result. # # All attempts to rewrite this macro with __builtin_constant_p() failed # with older compilers (e.g. gcc 4.4)[2]. However, Martin Uecker, # constructed[3] a mind-shattering solution that works everywhere. # Cthulhu fhtagn! # # This patch updates the min()/max() macros to evaluate to a constant # expression when called on constant expression arguments. This removes # several false-positive stack VLA warnings from an x86 allmodconfig build # when -Wvla is added: # # $ diff -u before.txt after.txt \| grep ^- # -drivers/input/touchscreen/cyttsp4_core.c:871:2: warning: ISO C90 forbids variable length array ‘ids’ [-Wvla] # -fs/btrfs/tree-checker.c:344:4: warning: ISO C90 forbids variable length array ‘namebuf’ [-Wvla] # -lib/vsprintf.c:747:2: warning: ISO C90 forbids variable length array ‘sym’ [-Wvla] # -net/ipv4/proc.c:403:2: warning: ISO C90 forbids variable length array ‘buff’ [-Wvla] # -net/ipv6/proc.c:198:2: warning: ISO C90 forbids variable length array ‘buff’ [-Wvla] # -net/ipv6/proc.c:218:2: warning: ISO C90 forbids variable length array ‘buff64’ [-Wvla] # # This also updates two cases where different enums were being compared # and explicitly casts them to int (which matches the old side-effect of # the single-evaluation code): one in tpm/tpm_tis_core.h, and one in # drm/drm_color_mgmt.c. # # [1] https://lkml.org/lkml/2018/3/7/621 # [2] https://lkml.org/lkml/2018/3/10/170 # [3] https://lkml.org/lkml/2018/3/20/845 # # Co-Developed-by: Linus Torvalds <torvalds@linux-foundation.org> # Co-Developed-by: Martin Uecker <Martin.Uecker@med.uni-goettingen.de> # Signed-off-by: Kees Cook <keescook@chromium.org> # Acked-by: Ingo Molnar <mingo@kernel.org> # Acked-by: Miguel Ojeda <miguel.ojeda.sandonis@gmail.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < git log --format=%s --max-count=1 3c8ba0d61d04ced9f8d9ff93977995a9e4e96e91 # < make -s -j 10 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_64BIT=n # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # yes \n \| make -s -j 10 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 10 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- In file included from /kisskb/src/arch/sparc/include/asm/cacheflush.h:11:0, from /kisskb/src/drivers/android/binder.c:54: /kisskb/src/arch/sparc/include/asm/cacheflush_32.h:40:37: warning: 'struct page' declared inside parameter list void sparc_flush_page_to_ram(struct page page);
