| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Initially, Scudo had a monolithic design where both C and C++ functions were living in the same library. This was not necessarily ideal, and with the work on -fsanitize=scudo, it became more apparent that this needed to change. We are splitting the new/delete interceptor in their own C++ library. This allows more flexibility, notably with regard to std::bad_alloc when the work is done. This also allows us to not link new & delete when using pure C. Additionally, we add the UBSan runtimes with Scudo, in order to be able to have a -fsanitize=scudo,undefined in Clang (see work in D39334). The changes in this patch: - split the cxx specific code in the scudo cmake file into a new library; (remove the spurious foreach loop, that was not necessary) - add the UBSan runtimes (both C and C++); - change the test cmake file to allow for specific C & C++ tests; - make C tests pure C, rename their extension accordingly.

Creating a new revision, since the old one was getting a bit old/crowded. In Fuchsia, MmapNoAccess/MmapFixedOrDie are implemented using a global VMAR, which means that MmapNoAccess can only be called once. This works for the sanitizer allocator but *not* for the Scudo allocator. Hence, this changeset introduces a new ReservedAddressRange object to serve as the new API for these calls. In this changeset, the object still calls into the old Mmap implementations. The next changeset two changesets will convert the sanitizer and scudo allocators to use the new APIs, respectively. (ReservedAddressRange will replace the SecondaryHeader in Scudo.) Finally, a last changeset will update the Fuchsia implementation.

| * [scudo] Allow to specify the maximum number of TSDs at compile timeKostya Kortchinsky2017-10-272-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This introduces `SCUDO_MAX_CACHES` allowing to define an upper bound to the number of `ScudoTSD` created in the Shared TSD model (by default 32U). This name felt clearer than `SCUDO_MAX_TSDS` which is technically what it really is. I am opened to suggestions if that doesn't feel right. Additionally change `getNumberOfCPUs` to return a `u32` to be more consistent.

| * [Sanitizers] Set default allocator_release_to_os_interval_ms to 5 secondsAlex Shlyapnikov2017-10-262-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: With new release to OS approach (see D38245) it's reasonable to enable it by default. Setting allocator_release_to_os_interval_ms to 5000 seems to be a reasonable default (might be tuned later, based on the feedback). Also delaying the first release to OS in each bucket for at least allocator_release_to_os_interval_ms after the first allocation to prevent just allocated memory to be madvised back to OS and let short lived processes to avoid release to OS overhead altogether.

| * [sanitizer] Random shuffling of chunks for the 32-bit Primary AllocatorKostya Kortchinsky2017-10-254-26/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The 64-bit primary has had random shuffling of chunks for a while, this implements it for the 32-bit primary. Scudo is currently the only user of `kRandomShuffleChunks`. This change consists of a few modifications: - move the random shuffling functions out of the 64-bit primary to `sanitizer_common.h`. Alternatively I could move them to `sanitizer_allocator.h` as they are only used in the allocator, I don't feel strongly either way; - small change in the 64-bit primary to make the `rand_state` initialization `UNLIKELY`; - addition of a `rand_state` in the 32-bit primary's `SizeClassInfo` and shuffling of chunks when populating the free list. - enabling the `random_shuffle.cpp` test on platforms using the 32-bit primary for Scudo. Some comments on why the shuffling is done that way. Initially I just implemented a `Shuffle` function in the `TransferBatch` which was simpler but I came to realize this wasn't good enough: for chunks of 10000 bytes for example, with a `CompactSizeClassMap`, a batch holds only 1 chunk, meaning shuffling the batch has no effect, while a region is usually 1MB, eg: 104 chunks of that size. So I decided to "stage" the newly gathered chunks in a temporary array that would be shuffled prior to placing the chunks in batches. The result is looping twice through n_chunks even if shuffling is not enabled, but I didn't notice any significant significant performance impact.

| * [Sanitizers] ASan: detect new/delete calls with mismatched alignment.Alex Shlyapnikov2017-10-2510-87/+298
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ASan allocator stores the requested alignment for new and new[] calls and on delete and delete[] verifies that alignments do match. The representable alignments are: default alignment, 8, 16, 32, 64, 128, 256 and 512 bytes. Alignments > 512 are stored as 512, hence two different alignments > 512 will pass the check (possibly masking the bug), but limited memory requirements deemed to be a resonable tradeoff for relaxed conditions. The feature is controlled by new_delete_type_mismatch flag, the same one protecting new/delete matching size check.
