Introduce -fsanitize-trap= flag. This flag controls whether a given sanitizer traps upon detecting an error. It currently only supports UBSan. The existing flag -fsanitize-undefined-trap-on-error has been made an alias of -fsanitize-trap=undefined. This change also cleans up some awkward behavior around the combination of -fsanitize-trap=undefined and -fsanitize=undefined. Previously we would reject command lines containing the combination of these two flags, as -fsanitize=vptr is not compatible with trapping. This required the creation of -fsanitize=undefined-trap, which excluded -fsanitize=vptr (and -fsanitize=function, but this seems like an oversight). Now, -fsanitize=undefined is an alias for -fsanitize=undefined-trap, and if -fsanitize-trap=undefined is specified, we treat -fsanitize=vptr as an "unsupported" flag, which means that we error out if the flag is specified explicitly, but implicitly disable it if the flag was implied by -fsanitize=undefined.

[ubsan] Diagnose invalid uses of builtins (clang) On some targets, passing zero to the clz() or ctz() builtins has undefined behavior. I ran into this issue while debugging UB in __hash_table from libcxx: the bug I was seeing manifested itself differently under -O0 vs -Os, due to a UB call to clz() (see: libcxx/r304617).

[Sanitizers] Provide better diagnostic for sanitizers unsupported for target triple. Introduce ToolChain::getSupportedSanitizers() that would return the set of sanitizers available on given toolchain. By default, these are sanitizers which don't necessarily require runtime support and are not toolchain- or architecture-dependent. Sanitizers (ASan, DFSan, TSan, MSan etc.) which cannot function without runtime library are marked as supported only on platforms for which we actually build these runtimes. This would allow more fine-grained checks in the future: for instance, we have to restrict availability of -fsanitize=vptr to Mac OS 10.9+ (PR23539). Update test cases accrodingly: add tests for certain unsupported configurations, remove test cases for -fsanitize=vptr + PS4 integration, as we don't build the runtime for PS4 at the moment. This change was first submitted as r239953 and reverted in r239958. The problem was and still is in Darwin toolchains, which get the knowledge about target platform too late after initializaition, while now we require this information when ToolChain::getSanitizerArgs() is called. r240170 works around this issue. llvm-svn: 240179

Driver: add support for linking the UBSan runtime library on Windows. On Windows the user may invoke the linker directly, so we might not have an opportunity to add runtime library flags to the linker command line. Instead, instruct the code generator to embed linker directive in the object file that cause the required runtime libraries to be linked. We might also want to do something similar for ASan, but it seems to have its own special complexities which may make this infeasible.

[Driver] Don't enable -fsanitize-use-after-scope when ASan is disabled When enabling any sanitizer, -fsanitize-use-after-scope is enabled by default. This doesn't actually turn ASan on, because we've been getting lucky and there are extra checks in BackendUtil that stop this from happening.

Allow to disable all sanitizers with "-fno-sanitize=all" option. Summary: This patch adds "all" sanitizer group. A shortcut "-fno-sanitize=all" can be used to disable all sanitizers for a given source file. "-fsanitize=all" option makes no sense, and will produce an error. This group can also be useful when we add "-fsanitize-recover=<list>" options (patch in http://reviews.llvm.org/D6302), as it would allow to conveniently enable/disable recovery for all specified sanitizers.

The RTTIMode algorithm is: - If -mkernel, -fapple-kext, or -fno-rtti are passed, rtti was disabled explicitly; - If -frtti was passed or we're not targetting the PS4, rtti is enabled; - If -fexceptions or -fcxx-exceptions was passed and we're targetting the PS4, rtti was enabled implicitly; - If we're targetting the PS4, rtti is disabled implicitly; - Otherwise, rtti is enabled; Since the only flag needed to pass to -cc1 is -fno-rtti if we want to disable it, there's no problem in saying rtti is enabled if we're compiling C code, so we don't look at the input file type. addExceptionArgs now looks at the RTTIMode and warns that rtti is being enabled implicitly if targetting the PS4 and exceptions are on. It also errors out if, targetting the PS4, -fno-rtti was passed, and exceptions were turned on. SanitizerArgs now errors out if rtti was disabled explicitly and the vptr sanitizer was enabled implicitly, but just turns off vptr if rtti is disabled but -fsanitize=undefined was passed. Also fixed tests, removed duplicate name from addExceptionArgs comment, and added one or two surrounding lines when running clang-format. This changes test/Driver/fsanitize.c to make it not expect a warning when passed -fsanitize=undefined -fno-rtti, but expect vptr to not be on. Removed all users and definition of SanitizerArgs::sanitizesVptr().

Add -fsanitize=<sanitizers> argument to driver and frontend, and add -fno-sanitize=<sanitizers> argument to driver. These allow ASan, TSan, and the various UBSan checks to be enabled and disabled separately. Right now, the different modes can't be combined, but the intention is that combining UBSan and the other sanitizers will be permitted in the near future. Currently, the UBSan checks will all be enabled if any of them is; that will be fixed by the next patch. llvm-svn: 167411

[asan] Turn -fsanitize-address-use-after-scope on by default [clang part] AddressSanitizer has an optional compile-time flag, -fsanitize-address-use-after-scope, which enables detection of use-after-scope bugs. We'd like to have this feature on by default, because it is already very well tested, it's used in several projects already (LLVM automatically enables it when using -DLLVM_USE_SANITIZER=Address), it's low overhead and there are no known issues or incompatibilities. This patch enables use-after-scope by default via the Clang driver, where we set true as the default value for AsanUseAfterScope. This also causes the lifetime markers to be generated whenever fsanitize=address is used. This has some nice consequences, e.g. we now have line numbers for all local variables.

Restructure the propagation of -fPIC/-fPIE. The PIC and PIE levels are not independent. In fact, if PIE is defined it is always the same as PIC. This is clear in the driver where ParsePICArgs returns a PIC level and a IsPIE boolean. Unfortunately that is currently lost and we pass two redundant levels down the pipeline.

[ubsan] Diagnose invalid uses of builtins (clang) On some targets, passing zero to the clz() or ctz() builtins has undefined behavior.

// CHECK-NO-RECOVER-UBSAN-NOT: sanitize-recover
Reimplement -fsanitize-recover family of flags. Introduce the following -fsanitize-recover flags: - -fsanitize-recover=<list>: Enable recovery for selected checks or group of checks. It is forbidden to explicitly list unrecoverable sanitizers here (that is, "address", "unreachable", "return"). - -fno-sanitize-recover=<list>: Disable recovery for selected checks or group of checks. - -f(no-)?sanitize-recover is now a synonym for -f(no-)?sanitize-recover=undefined,integer and will soon be deprecated. These flags are parsed left to right, and mask of "recoverable" sanitizer is updated accordingly, much like what we do for -fsanitize= flags. -fsanitize= and -fsanitize-recover= flag families are independent. CodeGen change: If there is a single UBSan handler function, responsible for implementing multiple checks, which have different recoverable setting, then we emit two handler calls instead of one: the first one for the set of "unrecoverable" checks, another one - for set of "recoverable" checks. If all checks implemented by a handler have the same recoverability setting, then the generated code will be the same. llvm-svn: 225719

[ubsan] Have -fsanitize=vptr emit a null check if -fsanitize=null isn't available In r309007, I made -fsanitize=null a hard prerequisite for -fsanitize=vptr. I did not see the need for the two checks to have separate null checking logic for the same pointer. I expected the two checks to either always be enabled together, or to be mutually compatible. In the mailing list discussion re: r309007 it became clear that that isn't the case. If a codebase is -fsanitize=vptr clean but not -fsanitize=null clean, it's useful to have -fsanitize=vptr emit its own null check. That's what this patch does: with it, -fsanitize=vptr can be used without -fsanitize=null. Differential Revision: https://reviews.llvm.org/D36112 llvm-svn: 309846

[Sanitizers] Provide better diagnostic for sanitizers unsupported for target triple. Introduce ToolChain::getSupportedSanitizers() that would return the set of sanitizers available on given toolchain. By default, these are sanitizers which don't necessarily require runtime support and are not toolchain- or architecture-dependent. Sanitizers (ASan, DFSan, TSan, MSan etc.) which cannot function without runtime library are marked as supported only on platforms for which we actually build these runtimes. This would allow more fine-grained checks in the future: for instance, we have to restrict availability of -fsanitize=vptr to Mac OS 10.9+ (PR23539). Update test cases accrodingly: add tests for certain unsupported configurations, remove test cases for -fsanitize=vptr + PS4 integration, as we don't build the runtime for PS4 at the moment. This change was first submitted as r239953 and reverted in r239958. The problem was and still is in Darwin toolchains, which get the knowledge about target platform too late after initializaition, while now we require this information when ToolChain::getSanitizerArgs() is called. r240170 works around this issue. llvm-svn: 240179

[CFI] Require -flto instead of implying it. Summary: This is unfortunate, but would let us land http://reviews.llvm.org/D10467, that makes ToolChains responsible for computing the set of sanitizers they support. Unfortunately, Darwin ToolChains doesn't know about actual OS they target until ToolChain::TranslateArgs() is called. In particular, it means we won't be able to construct SanitizerArgs for these ToolChains before that. This change removes SanitizerArgs::needsLTO() method, so that now ToolChain::IsUsingLTO(), which is called very early, doesn't need SanitizerArgs to implement this method. Docs and test cases are updated accordingly. See https://llvm.org/bugs/show_bug.cgi?id=23539, which describes why we start all these.

Introduce -fsanitize-trap= flag. This flag controls whether a given sanitizer traps upon detecting an error. It currently only supports UBSan. The existing flag -fsanitize-undefined-trap-on-error has been made an alias of -fsanitize-trap=undefined. This change also cleans up some awkward behavior around the combination of -fsanitize-trap=undefined and -fsanitize=undefined. Previously we would reject command lines containing the combination of these two flags, as -fsanitize=vptr is not compatible with trapping. This required the creation of -fsanitize=undefined-trap, which excluded -fsanitize=vptr (and -fsanitize=function, but this seems like an oversight). Now, -fsanitize=undefined is an alias for -fsanitize=undefined-trap, and if -fsanitize-trap=undefined is specified, we treat -fsanitize=vptr as an "unsupported" flag, which means that we error out if the flag is specified explicitly, but implicitly disable it if the flag was implied by -fsanitize=undefined.

[CFI] Diagnose when we CFI in diagnostic mode is unavailable on a toolchain. Summary: Namely, we must have proper C++ABI support in UBSan runtime. We don't have a good way to check for that, so just assume that C++ABI support is there whenever -fsanitize=vptr is supported (i.e. only on handful of platforms). Exact diagnostic is also tricky. It's not "cfi" that is unsupported, just the diagnostic mode. So, I suggest to report that "-fno-sanitize-trap=cfi-foobar" is incompatible with a given target toolchain.

[CFI] Add CFI-icall pointer type generalization Summary: This change allows generalizing pointers in type signatures used for cfi-icall by enabling the -fsanitize-cfi-icall-generalize-pointers flag. This works by 1) emitting an additional generalized type signature metadata node for functions and 2) llvm.type.test()ing for the generalized type for translation units with the flag specified. This flag is incompatible with -fsanitize-cfi-cross-dso because it would require emitting twice as many type hashes which would increase artifact size.

Protection against stack-based memory corruption errors using SafeStack: Clang command line option and function attribute This patch adds the -fsanitize=safe-stack command line argument for clang, which enables the Safe Stack protection (see http://reviews.llvm.org/D6094 for the detailed description of the Safe Stack). This patch is our implementation of the safe stack on top of Clang. The patches make the following changes: - Add -fsanitize=safe-stack and -fno-sanitize=safe-stack options to clang to control safe stack usage (the safe stack is disabled by default). - Add __attribute__((no_sanitize("safe-stack"))) attribute to clang that can be used to disable the safe stack for individual functions even when enabled globally.

[Driver] Add Scudo as a possible -fsanitize= option Summary: This change adds Scudo as a possible Sanitizer option via -fsanitize=. This allows for easier static & shared linking of the Scudo library, it allows us to enforce PIE (otherwise the security of the allocator is moot), and check for incompatible Sanitizers combo. In its current form, Scudo is not compatible with any other Sanitizer, but the plan is to make it work in conjunction with UBsan (-fsanitize=scudo,undefined), which will require additional work outside of the scope of this change.
