2021-02-01Fix __VERSIONER_NO_GUARD cases for availability.Dan Albert
libc++ still depends on these being declared even if they are unavailable. This results in a worse error message (a link error rather than a compiler diagnostic) if these functions end up being used, but without the decl headers like libc++'s math.h can't be included because it refers to an undeclared function. For the cases where weak symbols aren't being used, don't annotate these functions with their availability information. Also need to avoid using __builtin_available for this case because the NDK doesn't have __isOSVersionAtLeast yet. __ANDROID_UNGUARDED_AVAILABILITY__ is being used as a proxy for "building for the NDK" here because we don't have a good signal for that which works for both the NDK proper and the NDK-in-the-platform case.

Introduces new heap-zero-init API. We've realised that it's better to be able to individually control MTE and heap zero-init.

2021-01-15Guard __libc_current_sigrtmin/max with __builtin_availableJiyong Park
The two APIs were added for the API level 21 and beyond. Currently, its existence is tested using the null check which is done regardless of the min sdk version of the compilation unit. (which in turn required us to mark the API symbol weak regardless of the min sdk version.) Now, we have a better way of testing the API availability; __builtin_available. The null check is replaced with the call to the compiler-provided macro which determines if the code is running in a version of OS where the API is known to exist.

2021-01-15__INTRODUCED_IN macros add the availability attributeJiyong Park
__INTRODUCED_IN (and its variants) macro is used to mark the availability of an API symbol. The macros were used by the versioner tool for the NDK clients. When the Bionic headers are processed by the tool, APIs with the macros are guarded with __ANDROID_API__. e.g., void foo() __INTRDUCED_IN(30); is processed into \#if __ANDROID_API__ >= 30 void foo(); \#endif by the versioner. The macros however didn't play a role for other cases, e.g. OS components. This is too strict for NDK clients and too loose for the non-NDK clients. For the former, this completely hides the APIs that are newer than the min sdk version (__ANDROID_API__). For the latter, a call to such an API can be made without being guarded. This change is the first step towards a better way of handling the native APIs availability. The plan is that every NDK APIs are annotated with the availability attribute and callers are required to guard their API calls with a runtime check if the API is newer than the min sdk version of the caller. In this change, the macros now emits the availability attribute for the non-NDK clients (i.e. when not processed by versioner).

2021-01-14Make "disable memory mitigations" and "set heap tagging level" more available.Elliott Hughes
These were only available internally via android_mallopt(), but they're likely to be needed by more code in future, so move them into mallopt(). This change leaves the android_mallopt() options for now, but I plan on coming back to remove them after I've switched the handful of callers over to mallopt() instead.

They're both obsolescent in POSIX.1-2008, and you really shouldn't be using them, but since we can't actually delete them... This change makes them both obey $TMPDIR if set, and fall back to /data/local/tmp otherwise. That's as good as we've managed for anything else such as tmpfile(3). Also add some tests.

2020-09-23Enable BTI in bionic linkerTamas Petz
This patch adds support to load BTI-enabled objects. According to the ABI, BTI is recorded in the .note.gnu.property section. The new parser evaluates the property section, if exists. It searches for .note section with NT_GNU_PROPERTY_TYPE_0. Once found it tries to find GNU_PROPERTY_AARCH64_FEATURE_1_AND. The results are cached. The main change in linker is when protection of loaded ranges gets applied. When BTI is requested and the platform also supports it the prot flags have to be amended with PROT_BTI for executable ranges. Failing to add PROT_BTI flag would disable BTI protection. Moreover, adding the new PROT flag for shared objects without BTI compatibility would break applications. Kernel does not add PROT_BTI to a loaded ELF which has interpreter. Linker handles this case too. Test: 1. Flame boots 2. Tested on FVP with BTI enabled Change-Id: Iafdf223b74c6e75d9f17ca90500e6fe42c4c1218

2020-08-11Add api-level.h to dac, improve docs.Dan Albert
We don't list most of bionic on dac since it would be overwhelming for the current layout, but this file in particular seems useful, especially __ANDROID_API__. Unfortunately, c2devsite doesn't include macro documentation. Until then, it's still useful to include the functions defined in this header. I've also elaborated a bit in the __ANDROID_API__ documentation, since the existing phrasing led to confusion over whether it was closer to minSdkVersion or compileSdkVersion. In practice these are identical for the NDK, but if we switch to weakly-linked APIs via the availability attribute that would change.
