Sergey Matveev 544d07f861 [sanitizer] One does not simply intercept getifaddrs(). 
Upgrade the interceptor, and attempt to fix the Android build.

Kostya Serebryany 9ebd483017 [sanitizer] hide two functions in the __sanitizer namespace to avoid exporting them (gold complained)

Alexander Potapenko 2e7dc60ee3 [ASan] Replace the call to "vname" with "WRAP(vname)" in FORMAT_INTERCEPTOR_IMPL 
It's incorrect to call the function by its name in the interceptor, because that means WRAP(vname) on Linux and REAL(vname) on OSX.

This patch fixes asan/lit_tests/TestCases/printf-3.c on Mac.

llvm-svn: 199735
 2014-01-21 13:01:20 +00:00
Alexey Samsonov 00cd273c46 Sanitize printf functions. 
Intercept and sanitize arguments passed to printf functions in ASan and TSan
(don't do this in MSan for now). The checks are controlled by runtime flag
(off by default for now).

Patch http://llvm-reviews.chandlerc.com/D2480 by Yuri Gribov!

Chandler Carruth a989fb5ce7 Fix an ODR violation in the sanitizer runtimes. 
A helper function is a C++ function, and so even though one of the two
definitions is weak, it still technically triggers the ODR. Perhaps
these two definitions are ODR equivalent, but I'm not even confident in
that.

Instead, just define the function once, declare it as weak, and use
a wrapper that is clearly file-local. This avoids two definitions. Also
make the function extern "C" so that we can't even mess up the type
signature somehow or otherwise fail to match up the weak declaration
here with the interceptor defined elsewhere.

Evgeniy Stepanov 59bb0878e2 [msan] Tweak gethostbyname_r interceptor some more.

Evgeniy Stepanov 43fc44007d [msan] Fix gethostbyname_r and similar interceptors. 
*h_errno is written not on success, but on failure.
In fact, it seems like it can be written even when return value signals
success, so we just unpoison it in all cases.
