Evgeniy Stepanov 24c8d92fec [sanitizer] Intercept a subset of sunrpc interface (xdr_*). 
llvm-svn: 205627
 2014-04-04 14:51:23 +00:00
Evgeniy Stepanov 86a4d2c32b [sanitizer] Intercept fgetpwent / fgetgrent. 
These interceptors require deep unpoisoning of return values.
While at it, we do the same for all other pw/gr interceptors to
reduce dependency on libc implementation details.

Evgeniy Stepanov cba008e9c5 [asan] A different way of detectinb stack overflow. 
Instead of checking stack limits that are not well defined for the main thread,
we rely on siginfo::si_code and distance from SP.

introduced READWRITE ioctl type.

Evgeniy Stepanov 39cc337e20 [sanitizer] Change the way we use certain linux kernel headers. 
Some linux headers are broken on older kernels.
Instead of depending on the constants and types from such headers directly,
we provide our own definitions and then verify them with compile-time
assertions. This makes the dependency on the headers test-only and would allow
switching to some other way of testing on older kernels, or even disable the
tests as the last resort (after all, kernel interfaces are supposed to be
stable).

Evgeniy Stepanov 0bb7577d89 [sanitizer] Split platform_limits_posix into system- and kernel-dependent parts. 
This change moves everything depending on kernel headers (mostly ioctl types
and ids) into a separate source file. This will reduce the possibility of
header conflict on various platforms (most importantly, older glibc versions).

This change also removes 2 deprecated ioctls, and symbolic ids for other bunch
of ambiguous ioctls (i.e. same id is shared by ioctls with different memory
behavior).
