2017-12-18[asan] Add interceptor for printf_chkMaxim Ostapenko
There could be a situation when a specific DSO was built with FORTIFY_SOURCE option. In case asan-ed binary link against that DSO, libasan can't handle the possible memory error because it does not have interceptors for spinrtf_chk, snprintf_chk, vprintf_chk, vsnprintf_chk, __fprintf_chk functions. Let's interceptors for them. Patch by Denis Khalikov.

2017-12-14[Sanitizers] Basic sanitizer Solaris support (PR 33274)Kamil Rytarowski
Summary: This is the first mostly working version of the Sanitizer port to 32-bit Solaris/x86. It is currently based on Solaris 11.4 Beta. This part was initially developed inside libsanitizer in the GCC tree and should apply to both. Subsequent parts will address changes to clang, the compiler-rt build system and testsuite. I'm not yet sure what the right patch granularity is: if it's profitable to split the patch up, I'd like to get guidance on how to do so. Most of the changes are probably straightforward with a few exceptions: * The Solaris syscall interface isn't stable, undocumented and can change within an OS release. The stable interface is the libc interface, which I'm using here, if possible using the internal _-prefixed names. * While the patch primarily target 32-bit x86, I've left a few sparc changes in. They cannot currently be used with clang due to a backend limitation, but have worked fine inside the gcc tree. * Some functions (e.g. largefile versions of functions like open64) only exist in 32-bit Solaris, so I've introduced a separate SANITIZER_SOLARIS32 to check for that. The patch (with the subsequent ones to be submitted shortly) was tested on i386-pc-solaris2.11. Only a few failures remain, some of them analyzed, some still TBD: AddressSanitizer-i386-sunos :: TestCases/Posix/concurrent_overflow.cc AddressSanitizer-i386-sunos :: TestCases/init-order-atexit.cc AddressSanitizer-i386-sunos :: TestCases/log-path_test.cc AddressSanitizer-i386-sunos :: TestCases/malloc-no-intercept.c AddressSanitizer-i386-sunos-dynamic :: TestCases/Posix/concurrent_overflow.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/Posix/start-deactivated.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/default_options.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/init-order-atexit.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/log-path_test.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/malloc-no-intercept.c SanitizerCommon-Unit :: ./Sanitizer-i386-Test/MemoryMappingLayout.DumpListOfModules SanitizerCommon-Unit :: ./Sanitizer-i386-Test/SanitizerCommon.PthreadDestructorIterations Maybe this is good enough the get the ball rolling.

2017-12-14Set of corrections for MSan/NetBSDKamil Rytarowski
Summary: Changes: - Don't attempt to intercept GLIBC specific functions like __strtol_internal. This is required to stop intercepting it as we leak dlerror(3) for dlsym(3) that cannot manage to find a symbol. - Correct interception of fstatat(2). - Don't run a test for fgetgrent_r() that is missing on NetBSD. - Correct link_map location (offset) in Obj_Entry on x86_64 and i386. - Stop intercepting getpshared-like functions in pthread(3). This is feature is not enabled by default on NetBSD as it's unfinished. - Switch intercepting from UTMP to UTMPX functions.

2017-08-01[sanitizer_common] Fuchsia support for interceptorsVitaly Buka
Summary: Actually Fuchsia non-support for interceptors. Fuchsia doesn't use interceptors in the common sense at all. Almost all system library functions don't need interception at all, because the system libraries are just themselves compiled with sanitizers enabled and have specific hook interfaces where needed to inform the sanitizer runtime about thread lifetimes and the like. For the few functions that do get intercepted, they don't use a generic mechanism like dlsym with RTLD_NEXT to find the underlying system library function. Instead, they use specific extra symbol names published by the system library (e.g. __unsanitized_memcpy). Submitted on behalf of Roland McGrath.

macOS Summary: In https://bugs.freebsd.org/215125 I was notified that some configure scripts attempt to test for the Linux-specific `mallinfo` and `mallopt` functions by compiling and linking small programs which references the functions, and observing whether that results in errors. FreeBSD and macOS do not have the `mallinfo` and `mallopt` functions, so normally these tests would fail, but when sanitizers are enabled, they incorrectly succeed, because the sanitizers define interceptors for these functions. This also applies to some other malloc-related functions, such as `memalign`, `pvalloc` and `cfree`. Fix this by not intercepting `mallinfo`, `mallopt`, `memalign`, `pvalloc` and `cfree` for FreeBSD and macOS, in all sanitizers.

2016-06-06This patch attempts to primitive support for Win64 asanEtienne Bergeron
Some known issues are: When "head" include instructions that involve branching, the "cut and paste" approach may break down in a way that function interception still work but calling back the original function does not work. The jmp [rip -8] saves some bytes in the "head" but finding the safe zone of 0xCC is not implemented yet. So it may stomp on preceding codes. The shadow offset is not working yet on Win64. More complexity maybe involved since there are some differences regarding virtual address space between Window 8 and Windows 8.1/10.
