2017-12-09Correct handling of the TLS/NetBSD block of the main programKamil Rytarowski
Summary: Include <sys/tls.h> for: - struct tls_tcb - thread control block structure - __HAVE___LWP_GETTCB_FAST - __lwp_gettcb_fast() is available - __HAVE___LWP_GETPRIVATE_FAST - __lwp_getprivate_fast() is available - __HAVE_TLS_VARIANT_I - TLS Variant I for this architecture - __HAVE_TLS_VARIANT_II - TLS Variant II for this architecture Rename ThreadSelfSegbase() to ThreadSelfTlsTcb and switch it to retrieve in a portable way TCB. Switch ThreadSelf() to retrieve pthread from struct tcb_tls. Use dl_iterate_phdr() to find out the size of TLS block of the main program. Correct the index of the TLS block of the main program (dlpi_tls_modid); it's 1, not 2. New NetBSD code is now CPU (NetBSD port) agnostic. Stop sharing the same code with FreeBSD.

2017-12-08[libFuzzer] Add support for Fuchsia OS.Matt Morehouse
Summary: This patch adds the initial support for Fuchsia. - LIBFUZZER_FUCHSIA is added as an OS type in FuzzerDefs.h - Fuchsia is, by design, not POSIX compliant. However, it does use ELF and supports common POSIX I/O functions. Thus, FuzzerExtFunctions.h and FuzzerIO.h are implemented by extending the header guards in FuzzerExtFunctionsWeak.cpp and FuzzerIOPosix.cpp to include LIBFUZZER_FUCHSIA. - The platform-specific portions of FuzzerUtil.h are implemented by FuzzerUtilFuchsia.cpp, which makes use of exception ports, syscalls, and the launchpad library. - The experimental equivalence server is not currently supported, so FuzzerShmem.h is implemented by stub methods in FuzzerShmemFuchsia.cpp. Any future implementation will likely involve VMOs. Tested with ASAN/SanCov on Fuchsia/x86-64 with the canonical toy fuzzer.

2017-12-08[scudo] Minor code generation improvementKostya Kortchinsky
Summary: It looks like clang was generating somewhat weird assembly with the current code. `FromPrimary`, even though `const`, was replaced every time with the code generated for `size <= SizeClassMap::kMaxSize` instead of using a variable or register, and `FromPrimary` didn't induce `ClassId != 0` for the compiler, so a dead branch was generated for `getActuallyAllocatedSize(Ptr, ClassId)` since it's never called for `ClassId = 0` (Secondary backed allocations) [this one was more wishful thinking on my side than anything else]. I rearranged the code bit so that the generated assembly is less clunky. Also changed 2 whitespace inconsistencies that were bothering me.

2017-12-06[libFuzzer] Decrease stack usage in unit testsKostya Serebryany
Summary: With 3 Dictionary objects, each containing space of ~16k DictionaryEntry objects, the MutationDispatcher object is fairly memory heavy. On platforms with a lower default stack size, this can cause panics in FuzzerUnittest as those tests stack-allocate the MutationDispatcher. This may be especially problematic for platforms that do not (yet) have a way to programmatically change their stack size, aside from link-time flags. In general, it seems more prudent to use the heap for an object of this size.

2017-12-06Correct atexit(3) support in MSan/NetBSDKamil Rytarowski
Summary: The NetBSD specific implementation of cxa_atexit() does not preserve the 2nd argument if dso is equal to NULL. Changes: - Split paths of handling intercepted __cxa_atexit() and atexit(3). This affects all supported Operating Systems. - Add a local stack-like structure to hold the __cxa_atexit() context. atexit(3) is documented in the C standard as calling callback from the earliest to the oldest entry. This path also fixes potential ABI problem of passing an argument to a function from the atexit(3) callback mechanism. - Allow usage of global vars with ctors in interceptors. This allows to use Vector without automatic cleaning up the structures. This code has been modeled after TSan implementation for the same functions.

2017-12-05[scudo] Get rid of the thread local PRNG & header saltKostya Kortchinsky
Summary: It was deemed that the salt in the chunk header didn't improve security significantly (and could actually decrease it). The initial idea was that the same chunk would different headers on different allocations, allowing for less predictability. The issue is that gathering the same chunk header with different salts can give information about the other "secrets" (cookie, pointer), and that if an attacker leaks a header, they can reuse it anyway for that same chunk anyway since we don't enforce the salt value. So we get rid of the salt in the header. This means we also get rid of the thread local Prng, and that we don't need a global Prng anymore as well. This makes everything faster. We reuse those 8 bits to store the `ClassId` of a chunk now (0 for a secondary based allocation). This way, we get some additional speed gains: - `ClassId` is computed outside of the locked block; - `getActuallyAllocatedSize` doesn't need the `GetSizeClass` call; - same for `deallocatePrimary`; We add a sanity check at init for this new field (all sanity checks are moved in their own function, `init` was getting crowded).

2017-12-05[XRay][compiler-rt] Implement XRay Basic Mode FilteringDean Michael Berris
Summary: This change implements the basic mode filtering similar to what we do in FDR mode. The implementation is slightly simpler in basic-mode filtering because we have less details to remember, but the idea is the same. At a high level, we do the following to decide when to filter function call records: - We maintain a per-thread "shadow stack" which keeps track of the XRay instrumented functions we've encountered in a thread's execution. - We push an entry onto the stack when we enter an XRay instrumented function, and note the CPU, TSC, and type of entry (whether we have payload or not when entering). - When we encounter an exit event, we determine whether the function being exited is the same function we've entered recently, was executing in the same CPU, and the delta of the recent TSC and the recorded TSC at the top of the stack is less than the equivalent amount of microseconds we're configured to ignore -- then we un-wind the record offset an appropriate number of times (so we can overwrite the records later). We also support limiting the stack depth of the recorded functions, so that we don't arbitrarily write deep function call stacks.

2017-12-05[XRay][compiler-rt] Implement logging implementation registrationDean Michael Berris
Summary: This change allows for registration of multiple logging implementations through a central mechanism in XRay, mapping an implementation to a "mode". Modes are strings that are used as keys to determine which implementation to install through a single API. This mechanism allows users to choose which implementation to install either from the environment variable 'XRAY_OPTIONS' with the `xray_mode=` flag, or programmatically using the `__xray_select_mode(...)` function. Here, we introduce two API functions for the XRay logging: __xray_log_register_mode(Mode, Impl): Associates an XRayLogImpl to a string Mode. We can only have one implementation associated with a given Mode. __xray_log_select_mode(Mode): Finds the associated Impl for Mode and installs it as if by calling `__xray_set_log_impl(...)`. Along with these changes, we also deprecate the xray_naive_log and xray_fdr_log flags and encourage users to instead use the xray_mode flag.

2017-12-04[libFuzzer] Encapsulate commands in a class.Matt Morehouse
Summary: To be more portable (especially w.r.t. platforms without system()), commands should be managed programmatically rather than via string manipulation on the command line. This change introduces Fuzzer::Command, with methods to manage arguments and flags, set output options, and execute the command.

2017-12-04[sanitizer] 64-bit allocator's PopulateFreeArray partial refactorKostya Kortchinsky
Summary: This is an attempt at making `PopulateFreeArray` less obscure, more consistent, and a tiny bit faster in some circumstances: - use more consistent variable names, that work both for the user & the metadata portions of the code; the purpose of the code is mostly the same for both regions, so it makes sense that the code should be mostly similar as well; - replace the while sum loops with a single `RoundUpTo`; - mask most of the metadata computations behind kMetadataSize, allowing some blocks to be completely optimized out if not use metadata; - `const` the constant variables; - add a `LIKELY` as the branch it applies to will almost always be taken.
