[GWP-ASan] Provide runtime configuration through an env var + sysprop. This patch introduces GWP-ASan system properties and environment variables to control the internal sampling rates of GWP-ASan. This can be used for: 1. "Torture testing" the system, i.e. running it under an extremely high sampling rate under GWP-ASan. 2. Increasing sampling remotely to allow further crash report collection of rare issues. There are three sets of system properites: 1. libc.debug.gwp_asan.*.system_default: Default values for native executables and system apps. 2. libc.debug.gwp_asan.*.app_default: Default values for non-system apps, and 3. libc.debug.gwp_asan.*.<basename/app_name>: Default values for an individual app or native process. There are three variables that can be changed: 1. The allocation sampling rate (default: 2500) - using the environment variable GWP_ASAN_SAMPLE_RATE or the libc.debug.gwp_asan.sample_rate.* system property. 2. The process sampling rate (default: 128 for system apps/processes, 1 for opted-in apps) - using the environment variable GWP_ASAN_PROCESS_SAMPLING or the libc.debug.gwp_asan.process_sampling.* system property, 3. The number of slots available (default: 32) - using the environment variable GWP_ASAN_MAX_ALLOCS or the libc.debug.gwp_asan.max_allocs.* system property. If not specified, #3 will be calculated as a ratio of the default |2500 SampleRate : 32 slots|. So, a sample rate of "1250" (i.e. twice as frequent sampling) will result in a doubling of the max_allocs to "64".

Add %b and %B support to the scanf/wscanf and strto*/wcsto* families. Coming to C23 via WG14 N2630. This one is a little interesting, because it actually changes existing behavior. Previously "0b101" would be parsed as "0", "b", "101" by these functions. I'm led to believe that glibc plans to actually have separate versions of these functions for C23 and pre-C23, so callers can have the behavior they (implicitly) specify by virtue of which -std= they compile with. Android has never really done anything like that, and I'm pretty sure app developers have more than enough to worry about with API levels without having to deal with the cartesian product of API level and C standard. Therefore, my plan A is "if you're running on Android >= U, you get C23 behavior". My plan B in the (I think unlikely) event that that actually causes trouble for anyone is "if you're _targeting_ Android >= U, you get C23 behavior". I don't think we'd actually want to have two versions of each of these functions under any circumstances --- that seems by far the most confusing option.

[GWP-ASan] Integrate GWP-ASan into bionc's malloc() (using hooks). This patch introduces GWP-ASan - a sampled allocator framework that finds use-after-free and heap-buffer-overflow bugs in production environments. GWP-ASan is being introduced in an always-disabled mode. This means that GWP-ASan will be permanently disabled until a further patch turns on support. As such, there should be no visible functional change for the time being. GWP-ASan requires -fno-emulated-tls wherever it's linked from. We intentionally link GWP-ASan into libc so that it's part of the initial set of libraries, and thus has static TLS storage (so we can use Initial-Exec TLS instead of Global-Dynamic). As a benefit, this reduces overhead for a sampled process. GWP-ASan is always initialised via. a call to mallopt(M_INITIALIZE_GWP_ASAN, which must be done before a process is multithreaded). More information about GWP-ASan can be found in the upstream documentation: http://llvm.org/docs/GwpAsan.html Bug: 135634846 Test: atest bionic Change-Id: Ib9bd33337d17dab39ac32f4536bff71bd23498b0

Use -fno-builtin for libc and libm. clang was getting in the way of a strftime(3) optimization, and smaller hammers weren't working, and this seems like the right choice for libc anyway? If we have code that can usefully be optimized, we should do it in the source. In general, though, no libc/libm author should be ignorant of memset(3) or memcpy(3), and would have used it themselves if it made sense. (And the compiler isn't using profiling data or anything; it's just always assuming it should use the functions, and doesn't consider whether the cost of the calls can be amortized or not.)

Add an API for per-process disabling memory initialization. Introduce an android_mallopt(M_DISABLE_MEMORY_MITIGATIONS) API call that may be used to disable zero- or pattern-init on non-MTE hardware, or memory tagging on MTE hardware. The intent is that this function may be called at any time, including when there are multiple threads running. Disabling zero- or pattern-init is quite trivial, we just need to set a global variable to 0 via a Scudo API call (although there will be some separate work required on the Scudo side to make this operation thread-safe). It is a bit more tricky to disable MTE across a process, because the kernel does not provide an API for disabling tag checking in all threads in a process, only per-thread. We need to send a signal to each of the process's threads with a handler that issues the required prctl call, and lock thread creation for the duration of the API call to avoid races between thread enumeration and calls to pthread_create().

sanitize: {
HWASan support in bionic. * Allow sanitization of libc (excluding existing global sanitizers) and disallow sanitization of linker. The latter has not been necessary before because HWASan is the first sanitizer to support static binaries (with the exception of CFI, which is not used globally). * Static binary startup: initialize HWASan shadow very early so that almost entire libc can be sanitized. The rest of initialization is done in a global constructor; until that is done sanitized code can run but can't report errors (will simply crash with SIGTRAP). * Switch malloc_common from je_* to __sanitizer_*. * Call hwasan functions when entering and leaving threads. We can not intercept pthread_create when libc depends on libclang_rt.hwasan. An alternative to this would be a callback interface like requested here: https://sourceware.org/glibc/wiki/ThreadPropertiesAPI All of the above is behind a compile-time check __has_feature(hwaddress_sanitizer). This means that HWASan actually requires libc to be instrumented, and would not work otherwise. It's an implementation choice that greatly reduces complexity of the tool. Instrumented libc also guarantees that hwasan is present and initialized in every process, which allows piecemeal sanitization (i.e. library w/o main executable, or even individual static libraries), unlike ASan.

Reuse the libm scalbn() as ldexp(). These are the same function for machines with binary floats (that is: all machines), but ldexp() is in libc rather than libm, so we can't just use an alias. We were using this duplicate copy of the code, but upstream FreeBSD has removed it, and I'd prefer to do the same. Longer term, we should just move all of libm into libc (but keep an empty libm for compatibility), but this is probably easier for now.

[GWP-ASan] Integrate GWP-ASan into bionc's malloc() (using hooks). This patch introduces GWP-ASan - a sampled allocator framework that finds use-after-free and heap-buffer-overflow bugs in production environments. GWP-ASan is being introduced in an always-disabled mode. This means that GWP-ASan will be permanently disabled until a further patch turns on support. As such, there should be no visible functional change for the time being. GWP-ASan requires -fno-emulated-tls wherever it's linked from. We intentionally link GWP-ASan into libc so that it's part of the initial set of libraries, and thus has static TLS storage (so we can use Initial-Exec TLS instead of Global-Dynamic). As a benefit, this reduces overhead for a sampled process. GWP-ASan is always initialised via. a call to mallopt(M_INITIALIZE_GWP_ASAN, which must be done before a process is multithreaded). More information about GWP-ASan can be found in the upstream documentation: http://llvm.org/docs/GwpAsan.html Bug: 135634846 Test: atest bionic Change-Id: Ib9bd33337d17dab39ac32f4536bff71bd23498b0

Move __libc_int0x80 to an assembly file Bug: http://b/157081822 If __libc_int0x80 is in a C/C++ file, Clang's coverage instrumentation adds instructions to count the number of times it gets executed [1]. With coverage instrumentation, __libc_sysinfo, used on 32-bit x86, is initialized to the wrong value, causing dl.preinit_system_calls to fail. Moving the function to an assembly file leaves __libc_sysinfo properly initialized. [1] We could change clang so it doesn't instrument functions marked __attribute__((naked)) as a followup.

Disable stack protector for __libc_preinit __libc_preinit sets up the stack protector global cookie value, and thus cannot intialize a stack protector cookie for itself in the function prologue. LTO compilation can inline functions requiring a stack protector into __libc_preinit.

Align Soong builds closer to Make This moves the Android.bp file to use wildcards in the same places that they're using in the Android.mk file. It also fixes a file that was in a different order. Make and Soong still produce binaries with object files in different orders, but that's due to Make reordering the object files based on compile type. Soong keeps the original specified order. It's not possible to emulate the reordered files in the Android.bp, since the arch-specific files won't interleave properly. Change-Id: I9052b3ed7c523c13df5cbe606f913c32c88c7c5f

Expose tzalloc()/localtime_rz()/mktime_z()/tzfree(). * Rationale The question often comes up of how to use multiple time zones in C code. If you're single-threaded, you can just use setenv() to manipulate $TZ. toybox does this, for example. But that's not thread-safe in two distinct ways: firstly, getenv() is not thread-safe with respect to modifications to the environment (and between the way putenv() is specified and the existence of environ, it's not obvious how to fully fix that), and secondly the _caller_ needs to ensure that no other threads are using tzset() or any function that behaves "as if" tzset() was called (which is neither easy to determine nor easy to ensure). This isn't a bigger problem because most of the time the right answer is to stop pretending that libc is at all suitable for any i18n, and switch to icu4c instead. (The NDK icu4c headers do not include ucal_*, so this is not a realistic option for most applications.) But what if you're somewhere in between? Like the rust chrono library, for example? What then? Currently their "least worst" option is to reinvent the entire wheel and read our tzdata files. Which isn't a great solution for anyone, for obvious maintainability reasons. So it's probably time we broke the catch-22 here and joined NetBSD in offering a less broken API than standard C has for the last 40 years. Sure, any would-be caller will have to have a separate "is this Android?" and even "is this API level >= 35?" path, but that will fix itself sometime in the 2030s when developers can just assume "yes, it is", whereas if we keep putting off exposing anything, this problem never gets solved. (No-one's bothered to try to implement the std::chrono::time_zone functionality in libc++ yet, but they'll face a similar problem if/when they do.) * Implementation The good news is that tzcode already implements these functions, so there's relatively little here. I've chosen not to expose `struct state` because `struct __timezone_t` makes for clearer error messages, given that compiler diagnostics will show the underlying type name (`struct __timezone_t*`) rather than the typedef name (`timezone_t`) that's used in calling code. I've moved us over to FreeBSD's wcsftime() rather than keep the OpenBSD one building --- I've long wanted to only have one implementation here, and FreeBSD is already doing the "convert back and forth, calling the non-wide function in the middle" dance that I'd hoped to get round to doing myself someday. This should mean that our strftime() and wcsftime() behaviors can't easily diverge in future, plus macOS/iOS are mostly FreeBSD, so any bugs will likely be interoperable with the other major mobile operating system, so there's something nice for everyone there! The FreeBSD wcsftime() implementation includes a wcsftime_l() implementation, so that's one stub we can remove. The flip side of that is that it uses mbsrtowcs_l() and wcsrtombs_l() which we didn't previously have. So expose those as aliases of mbsrtowcs() and wcsrtombs().

Fix tzalloc(nullptr) and add a test. This works (by reading /etc/localtime) on NetBSD, but not on Android since we have no such file. Fix that by using our equivalent system property instead. Also s/time zone/timezone/ in documentation and comments. We've always been inconsistent about this (as is upstream in code comments and documentation) but it seems especially odd now we expose a _type_ that spells it "timezone" to talk of "time zone" even as we're describing that type and its associated functions.

Bump tzcode from 2016g to 2022a*. Upstream has renamed tzsetlcl to tzset_unlocked. As bionic's implementation of tzset_unlock differs from upstream, these changes were skipped. Also, upstream has removed constants (SECSPERMIN, etc) from tzfile.h. As they are used in strptime.c, I've decided to leave them in tzfile.h and to not bring them into strptime.c. HAVE_TZNAME and USG_COMPAT flags semantics were updated, thus setting their values to 2 in Android.bp file. See https://github.com/eggert/tz/commit/1a27ec76bc436a64070461bbbf28e0511c7cf3b8 * https://github.com/eggert/tz/commit/4742526b7e8a0f26adaf068c9f5c0bc0870909e7 and https://github.com/eggert/tz/commit/0e8f0b06ac2f65d0c54a91121da09c8662cd88e6 were picked up, which are not part of 2022a.

Expose tzalloc()/localtime_rz()/mktime_z()/tzfree(). * Rationale The question often comes up of how to use multiple time zones in C code. If you're single-threaded, you can just use setenv() to manipulate $TZ. toybox does this, for example. But that's not thread-safe in two distinct ways: firstly, getenv() is not thread-safe with respect to modifications to the environment (and between the way putenv() is specified and the existence of environ, it's not obvious how to fully fix that), and secondly the _caller_ needs to ensure that no other threads are using tzset() or any function that behaves "as if" tzset() was called (which is neither easy to determine nor easy to ensure). This isn't a bigger problem because most of the time the right answer is to stop pretending that libc is at all suitable for any i18n, and switch to icu4c instead. (The NDK icu4c headers do not include ucal_*, so this is not a realistic option for most applications.) But what if you're somewhere in between? Like the rust chrono library, for example? What then? Currently their "least worst" option is to reinvent the entire wheel and read our tzdata files. Which isn't a great solution for anyone, for obvious maintainability reasons. So it's probably time we broke the catch-22 here and joined NetBSD in offering a less broken API than standard C has for the last 40 years. Sure, any would-be caller will have to have a separate "is this Android?" and even "is this API level >= 35?" path, but that will fix itself sometime in the 2030s when developers can just assume "yes, it is", whereas if we keep putting off exposing anything, this problem never gets solved. (No-one's bothered to try to implement the std::chrono::time_zone functionality in libc++ yet, but they'll face a similar problem if/when they do.) * Implementation The good news is that tzcode already implements these functions, so there's relatively little here. I've chosen not to expose `struct state` because `struct __timezone_t` makes for clearer error messages, given that compiler diagnostics will show the underlying type name (`struct __timezone_t*`) rather than the typedef name (`timezone_t`) that's used in calling code. I've moved us over to FreeBSD's wcsftime() rather than keep the OpenBSD one building --- I've long wanted to only have one implementation here, and FreeBSD is already doing the "convert back and forth, calling the non-wide function in the middle" dance that I'd hoped to get round to doing myself someday. This should mean that our strftime() and wcsftime() behaviors can't easily diverge in future, plus macOS/iOS are mostly FreeBSD, so any bugs will likely be interoperable with the other major mobile operating system, so there's something nice for everyone there! The FreeBSD wcsftime() implementation includes a wcsftime_l() implementation, so that's one stub we can remove. The flip side of that is that it uses mbsrtowcs_l() and wcsrtombs_l() which we didn't previously have. So expose those as aliases of mbsrtowcs() and wcsrtombs().

Make res_init() work again. Change 75830fb836621ebbcf68155e466983eb231f9ca1 to fix _nres initialization to be thread safe accidentally introduced a behavior change whereby res_init() became a no-op. It also failed to remove all direct accesses to _nres. Move the file over to C++ so we can let RAII ensure we're always holding a lock while using the global state, make all callers access the global state via this class, and restore the previous behavior of res_init().

Reuse the libm scalbn() as ldexp(). These are the same function for machines with binary floats (that is: all machines), but ldexp() is in libc rather than libm, so we can't just use an alias. We were using this duplicate copy of the code, but upstream FreeBSD has removed it, and I'd prefer to do the same. Longer term, we should just move all of libm into libc (but keep an empty libm for compatibility), but this is probably easier for now.

Align Soong builds closer to Make This moves the Android.bp file to use wildcards in the same places that they're using in the Android.mk file. It also fixes a file that was in a different order. Make and Soong still produce binaries with object files in different orders, but that's due to Make reordering the object files based on compile type. Soong keeps the original specified order. It's not possible to emulate the reordered files in the Android.bp, since the arch-specific files won't interleave properly. Change-Id: I9052b3ed7c523c13df5cbe606f913c32c88c7c5f

Start de-duplicating the regular and wide printf implementations. This patch switches to C++ (in anticipation of needing it later), removes a little duplication (via a macro for now), and ensures uniform support for %C/%lc and %S/%ls between regular and wide (with new tests). Since it's so hard to debug problems in printf (as the time I've wasted already today will testify), that's all I want to do in this change. The other 500 lines of diff can wait... (Also merge "floatio.h" into "local.h" now all the users are in forked code.) Bug: http://b/67371539 Test: ran tests Change-Id: I083353d89c32b9302d759ca6967cc6d8a62cd8a5

Rewrite getentropy. The error handling was a mess, resulting in an infinite loop (and a test timeout) if you actually took the /dev/urandom fallback. I'm also unconvinced that the getrandom(2) path was correct because of the various reasons why we might get a short count back (http://man7.org/linux/man-pages/man2/getrandom.2.html). In this version, the two paths look very similar except for the getrandom(2) failure case, where it's now much clearer that we just give up so that we can boot (http://b/33059407).

riscv64: fix ODR violations. Rather than do the work to fix the ODR violations while preserving non-V, let's just remove the non-V code. Android will require V anyway, and anyone trying to work on a non-V system in the meantime already needs a bunch of patches to the build system and ART, so one more shouldn't hurt too much.

Rewrite getentropy. The error handling was a mess, resulting in an infinite loop (and a test timeout) if you actually took the /dev/urandom fallback. I'm also unconvinced that the getrandom(2) path was correct because of the various reasons why we might get a short count back (http://man7.org/linux/man-pages/man2/getrandom.2.html). In this version, the two paths look very similar except for the getrandom(2) failure case, where it's now much clearer that we just give up so that we can boot (http://b/33059407).

Break android_set_abort_message out of libc_logging. libc_logging is getting statically linked into the crash handler library, resulting in two copies of the abort message code existing in processes, one in the linker, and one in the crash handler.

Add ARM EABI function __aeabi_read_tp By default, Clang uses this arm32 function to read the thread pointer, either for ELF TLS or via __builtin_thread_pointer(). It's probably better to inline the cp15 access using -mtp=cp15, but that's not the default yet. See https://reviews.llvm.org/D34878?id=114573.

riscv64: fix ODR violations. Rather than do the work to fix the ODR violations while preserving non-V, let's just remove the non-V code. Android will require V anyway, and anyone trying to work on a non-V system in the meantime already needs a bunch of patches to the build system and ART, so one more shouldn't hurt too much.

avx2 implementation for memset. This patch includes handwritten avx2 assembly for memset 64-bit. Uses non-temporal stores for very large sizes. Also includes dynamic dispatch for APIs having multiple implementations. Convincing benchmark improvements for sizes above 512 bytes, and although the slight regression for small sizes is unfortunate, it's probably small enough to be okay?

libc: Add support to allow library calls to find appropriate shell executable for a process Library calls like system() and popen() invoke the shell executable pointed to by '_PATH_BSHELL' in order to run the command passed into the function. The _PATH_BSHELL points to /system/bin/sh by default and thus breaks any vendor process trying to use system() / popen(), as they are denied access to system shell by selinux. This CL make necessary changes, so the implmentations of system() and popen() can use the appropriate shell (e.g. /vendor/bin/sh for processes running out of /vendor partition). Also, changes the implementation of system() and popen(). Bug: 64832610 Test: Manual, Using a test program running from /system/bin and /vendor/bin to ensure correct shell is being used.

Always use CLOCK_MONOTONIC for pthreads and semaphores pthread's and semaphore's default behavior is to use CLOCK_REALTIME, however this behavior is essentially never intended, as that clock is prone to change discontinuously. What users really intend is to use CLOCK_MONOTONIC, however only pthread_cond_timedwait() provides this as an option and even there, a large amount of existing code does not opt into CLOCK_MONOTONIC. We have seen numerous bugs directly attributable to this difference. Therefore, we provide this general workaround to always use CLOCK_MONOTONIC for waiting, regardless of what the input timespec is. Specifically this impacts the below APIs: pthread_mutex_timedlock() pthread_cond_timedwait() pthread_rwlock_timedrdlock() pthread_rwlock_timedwrlock() sem_timedwait() Test: boot bullhead, boot sailfish Test: bionic pthread/semaphore unit tests Test: check that pthread_cond_timedwait() timeouts are uneffected by CLOCK_REALTIME time changes Bug: 64694413 Bug: 64623895 Bug: 35756266 Bug: 35678943 Change-Id: Ibba98f5d88be1c306d14e9b9366302ecbef6d534

Add a tool to track down fd leaks. Add a hook that's called upon file descriptor creation to libc, and a library that uses it to capture backtraces for file descriptor creation, to make it easier to hunt down file descriptor leaks. Currently, this doesn't capture all of the ways of creating a file descriptor, but completeness isn't required for this to be useful as long as leaked file descriptors are created with a function that is tracked. The primary unhandled case is binder, which receives file descriptors as a payload in a not-trivially-parsable byte blob, but there's a chance that the leak we're currently trying to track down isn't of a file descriptor received over binder, so leave that for later.

Add a tool to track down fd leaks. Add a hook that's called upon file descriptor creation to libc, and a library that uses it to capture backtraces for file descriptor creation, to make it easier to hunt down file descriptor leaks. Currently, this doesn't capture all of the ways of creating a file descriptor, but completeness isn't required for this to be useful as long as leaked file descriptors are created with a function that is tracked. The primary unhandled case is binder, which receives file descriptors as a payload in a not-trivially-parsable byte blob, but there's a chance that the leak we're currently trying to track down isn't of a file descriptor received over binder, so leave that for later.

Rewrite getentropy. The error handling was a mess, resulting in an infinite loop (and a test timeout) if you actually took the /dev/urandom fallback. I'm also unconvinced that the getrandom(2) path was correct because of the various reasons why we might get a short count back (http://man7.org/linux/man-pages/man2/getrandom.2.html). In this version, the two paths look very similar except for the getrandom(2) failure case, where it's now much clearer that we just give up so that we can boot (http://b/33059407).

Support statvfs on API levels before 19. Split statfs and statvfs. The former has been available forever, and the latter is implemented in terms of the former. The implementation has been moved into headers so that it can be used at low API levels. There's no reason for any Android or Linux code to use statvfs rather than statfs, but code that needs to build on Darwin too will want to use statvfs because Darwin's statfs is very spartan.

threads.h: Add C11 thread support. FreeBSD, glibc, and musl have all implemented C11 threads at this point. POSIX is looking at how to align with it. Probably time to jump on the bandwagon ourselves... Implemented in the same style as <termios.h> so we can provide this functionality even on older API levels. This does mean that this is strictly more expensive than calling pthread functions directly. Although this isn't in POSIX yet, assume that it's going to be basically the same as C11 and add the header test anyway. We should revisit this when POSIX actually adds <threads.h>.

Make it easy to switch between scudo and jemalloc. Refactor some of the definitions to separate out all of the native allocator pieces into one place that can be changed easily. This should fix a few static libraries that appear to have accidentally included jemalloc wrapper functions. For example, I verified that libc_nomalloc.a no longer has references to any je_XXX functions. Modify the bionic_libc_platform_headers to not include any libraries. If this isn't updated, soong thinks there are cycles when used by libscudo. To enable scudo, change the libc_native_allocator_defaults defaults from libc_jemalloc5_defaults to libc_scudo_defaults and comment out the defaults: ["libc_scudo_wrapper_defaults"], line for the shared library libc_scudo. To do a final switch to scudo, it will be necessary to clean up some code in other parts of the tree, but this allows a single cl to enable or disable.

Reorganize static TLS memory for ELF TLS For ELF TLS "local-exec" accesses, the static linker assumes that an executable's TLS segment is located at a statically-known offset from the thread pointer (i.e. "variant 1" for ARM and "variant 2" for x86). Because these layouts are incompatible, Bionic generally needs to allocate its TLS slots differently between different architectures. To allow per-architecture TLS slots: - Replace the TLS_SLOT_xxx enumerators with macros. New ARM slots are generally negative, while new x86 slots are generally positive. - Define a bionic_tcb struct that provides two things: - a void* raw_slots_storage[BIONIC_TLS_SLOTS] field - an inline accessor function: void*& tls_slot(size_t tpindex); For ELF TLS, it's necessary to allocate a temporary TCB (i.e. TLS slots), because the runtime linker doesn't know how large the static TLS area is until after it has loaded all of the initial solibs. To accommodate Golang, it's necessary to allocate the pthread keys at a fixed, small, positive offset from the thread pointer. This CL moves the pthread keys into bionic_tls, then allocates a single mapping per thread that looks like so: - stack guard - stack [omitted for main thread and with pthread_attr_setstack] - static TLS: - bionic_tcb [exec TLS will either precede or succeed the TCB] - bionic_tls [prefixed by the pthread keys] - [solib TLS segments will be placed here] - guard page As before, if the new mapping includes a stack, the pthread_internal_t is allocated on it. At startup, Bionic allocates a temporary bionic_tcb object on the stack, then allocates a temporary bionic_tls object using mmap. This mmap is delayed because the linker can't currently call async_safe_fatal() before relocating itself. Later, Bionic allocates a stack-less thread mapping for the main thread, and copies slots from the temporary TCB to the new TCB. (See *::copy_from_bootstrap methods.) Bug: http://b/78026329 Test: bionic unit tests Test: verify that a Golang app still works Test: verify that a Golang app crashes if bionic_{tls,tcb} are swapped Merged-In: I6543063752f4ec8ef6dc9c7f2a06ce2a18fc5af3 Change-Id: I6543063752f4ec8ef6dc9c7f2a06ce2a18fc5af3 (cherry picked from commit 1e660b70da625fcbf1e43dfae09b7b4817fa1660)

Make it easy to switch between scudo and jemalloc. Refactor some of the definitions to separate out all of the native allocator pieces into one place that can be changed easily. This should fix a few static libraries that appear to have accidentally included jemalloc wrapper functions. For example, I verified that libc_nomalloc.a no longer has references to any je_XXX functions. Modify the bionic_libc_platform_headers to not include any libraries. If this isn't updated, soong thinks there are cycles when used by libscudo. To enable scudo, change the libc_native_allocator_defaults defaults from libc_jemalloc5_defaults to libc_scudo_defaults and comment out the defaults: ["libc_scudo_wrapper_defaults"], line for the shared library libc_scudo.

[GWP-ASan] Integrate GWP-ASan into bionc's malloc() (using hooks). This patch introduces GWP-ASan - a sampled allocator framework that finds use-after-free and heap-buffer-overflow bugs in production environments. GWP-ASan is being introduced in an always-disabled mode. This means that GWP-ASan will be permanently disabled until a further patch turns on support. As such, there should be no visible functional change for the time being. GWP-ASan requires -fno-emulated-tls wherever it's linked from. We intentionally link GWP-ASan into libc so that it's part of the initial set of libraries, and thus has static TLS storage (so we can use Initial-Exec TLS instead of Global-Dynamic). As a benefit, this reduces overhead for a sampled process. GWP-ASan is always initialised via. a call to mallopt(M_INITIALIZE_GWP_ASAN, which must be done before a process is multithreaded). More information about GWP-ASan can be found in the upstream documentation: http://llvm.org/docs/GwpAsan.html Bug: 135634846 Test: atest bionic Change-Id: Ib9bd33337d17dab39ac32f4536bff71bd23498b0

"bionic/malloc_common.cpp",
Add a platform API for setting an allocation limit. Introduce an M_SET_ALLOCATION_LIMIT enumerator for android_mallopt(), which can be used to set an upper bound on the total size of all allocations made using the memory allocation APIs. This is useful for programs such as audioextractor and mediaserver which need to set such a limit as a security mitigation. Currently these programs are using setrlimit(RLIMIT_AS) which isn't exactly what these programs want to control. RLIMIT_AS is also problematic under sanitizers which allocate large amounts of address space as shadow memory, and is especially problematic under shadow call stack, which requires 16MB of address space per thread. Add new unit tests for bionic. Add new unit tests for malloc debug that verify that when the limit is enabled, malloc debug still functions for nearly every allocation function. Bug: 118642754 Test: Ran bionic-unit-tests/bionic-unit-tests-static. Test: Ran malloc debug tests and perfetto integration tests. Change-Id: I735403c4d2c87f00fb2cdef81d00af0af446b2bb

"gwp_asan",
Add the recoverable GWP-ASan feature. GWP-ASan's recoverable mode was landed upstream in https://reviews.llvm.org/D140173. This mode allows for a use-after-free or a buffer-overflow bug to be detected by GWP-ASan, a crash report dumped, but then GWP-ASan (through the preCrashReport() and postCrashReportRecoverableOnly() hooks) will patch up the memory so that the process can continue, in spite of the memory safety bug. This is desirable, as it allows us to consider migrating non-system apps from opt-in GWP-ASan to opt-out GWP-ASan. The major concern was "if we make it opt-out, then bad apps will start crashing". If we don't crash, problem solved :). Obviously, we'll need to do this with an amount of process sampling to mitigate against the 70KiB memory overhead. The biggest problem is that the debuggerd signal handler isn't the first signal handler for apps, it's the sigchain handler inside of libart. Clearly, the sigchain handler needs to ask us whether the crash is GWP-ASan's fault, and if so, please patch up the allocator. Because of linker namespace restrictions, libart can't directly ask the linker (which is where debuggerd lies), so we provide a proxy function in libc. Test: Build the platform, run sanitizer-status and various test apps with recoverable gwp-asan. Assert that it doesn't crash, and we get a debuggerd report.

Use ifuncs in the linker Using ifuncs allows the linker to select faster versions of libc functions like strcmp, making linking faster. The linker continues to first initialize TLS, then call the ifunc resolvers. There are small amounts of code in Bionic that need to avoid calling functions selected using ifuncs (generally string.h APIs). I've tried to compile those pieces with -ffreestanding. Maybe it's unnecessary, but maybe it could help avoid compiler-inserted memset calls, and maybe it will be useful later on. The ifuncs are called in a special early pass using special __rel[a]_iplt_start / __rel[a]_iplt_end symbols. The linker will encounter the ifuncs again as R_*_IRELATIVE dynamic relocations, so they're skipped on the second pass. Break linker_main.cpp into its own liblinker_main library so it can be compiled with -ffreestanding. On walleye, this change fixes a recent 2.3% linker64 start-up time regression (156.6ms -> 160.2ms), but it also helps the 32-bit time by about 1.9% on the same benchmark. I'm measuring the run-time using a synthetic benchmark based on loading libandroid_servers.so.

Use ifuncs in the linker Using ifuncs allows the linker to select faster versions of libc functions like strcmp, making linking faster. The linker continues to first initialize TLS, then call the ifunc resolvers. There are small amounts of code in Bionic that need to avoid calling functions selected using ifuncs (generally string.h APIs). I've tried to compile those pieces with -ffreestanding. Maybe it's unnecessary, but maybe it could help avoid compiler-inserted memset calls, and maybe it will be useful later on. The ifuncs are called in a special early pass using special __rel[a]_iplt_start / __rel[a]_iplt_end symbols. The linker will encounter the ifuncs again as R_*_IRELATIVE dynamic relocations, so they're skipped on the second pass. Break linker_main.cpp into its own liblinker_main library so it can be compiled with -ffreestanding. On walleye, this change fixes a recent 2.3% linker64 start-up time regression (156.6ms -> 160.2ms), but it also helps the 32-bit time by about 1.9% on the same benchmark. I'm measuring the run-time using a synthetic benchmark based on loading libandroid_servers.so.

This flag prevents the compiler from inserting calls to libc functions in the ifunc resolver code, which will definitely cause problems if the libc function is itself an ifunc, but other calls that use the PLT may also be affected, since libc may not have been fully resolved yet.

Use ifuncs in the linker Using ifuncs allows the linker to select faster versions of libc functions like strcmp, making linking faster. The linker continues to first initialize TLS, then call the ifunc resolvers. There are small amounts of code in Bionic that need to avoid calling functions selected using ifuncs (generally string.h APIs). I've tried to compile those pieces with -ffreestanding. Maybe it's unnecessary, but maybe it could help avoid compiler-inserted memset calls, and maybe it will be useful later on. The ifuncs are called in a special early pass using special __rel[a]_iplt_start / __rel[a]_iplt_end symbols. The linker will encounter the ifuncs again as R_*_IRELATIVE dynamic relocations, so they're skipped on the second pass. Break linker_main.cpp into its own liblinker_main library so it can be compiled with -ffreestanding. On walleye, this change fixes a recent 2.3% linker64 start-up time regression (156.6ms -> 160.2ms), but it also helps the 32-bit time by about 1.9% on the same benchmark.

Move dl_unwind_find_exidx from libdl.a to libc.a arm32 has two special APIs to find exidx exception handling info, dl_unwind_find_exidx and __gnu_Unwind_Find_exdix. The two functions have identical behavior and function prototypes. libgcc's arm32 unwinder calls __gnu_Unwind_Find_exdix, whereas LLVM's libunwind previously called __gnu_Unwind_Find_exdix, but switched to dl_unwind_find_exidx as a result of three patches (D30306, D30681, D39468). In Bionic, for dynamic linking, __gnu_Unwind_Find_exdix in libc.so calls dl_unwind_find_exidx in libdl.so. For static executables, though, __gnu_Unwind_Find_exdix in libc.a used the __exidx_* symbols, while dl_unwind_find_exidx in libdl.a(libdl_static.o) was a return-0 no-op. To fix the LLVM unwinder, replace the no-op dl_unwind_find_exidx in libdl.a with a real function in libc.a(exidx_static.o), and have the GNU function call the dl function for more consistency with dynamic linking. dl_iterate_phdr follows a similar pattern, where the function exists in libc.a and libdl.so (not libc.so or libdl.a). This change makes unwinding work with an updated libunwind_llvm on arm32, and it helps to allow unwinding in static executables without libdl.a.

[GWP-ASan] Integrate GWP-ASan into bionc's malloc() (using hooks). This patch introduces GWP-ASan - a sampled allocator framework that finds use-after-free and heap-buffer-overflow bugs in production environments. GWP-ASan is being introduced in an always-disabled mode. This means that GWP-ASan will be permanently disabled until a further patch turns on support. As such, there should be no visible functional change for the time being. GWP-ASan requires -fno-emulated-tls wherever it's linked from. We intentionally link GWP-ASan into libc so that it's part of the initial set of libraries, and thus has static TLS storage (so we can use Initial-Exec TLS instead of Global-Dynamic). As a benefit, this reduces overhead for a sampled process. GWP-ASan is always initialised via. a call to mallopt(M_INITIALIZE_GWP_ASAN, which must be done before a process is multithreaded). More information about GWP-ASan can be found in the upstream documentation: http://llvm.org/docs/GwpAsan.html Bug: 135634846 Test: atest bionic Change-Id: Ib9bd33337d17dab39ac32f4536bff71bd23498b0

allow for heapprofd's signal to be multiplexed This patch refactors heapprofd_malloc to make it easier to reuse the reserved signal for multiple purposes. We define a new generic signal handler for profilers, which dispatches to more specific logic based on the signal's payload (si_value). The profiler signal handler is installed during libc preinit, after malloc initialization (so races against synchronous heapprofd initialization need not be considered). In terms of code organization, I copied the existing approach with a loosely referenced function in bionic_globals.h. Do tell if you'd rather a different approach here. The profileability of a process is quite tied to the malloc files/interfaces in bionic - in particular, it's set through android_mallopt. I do not change that, but instead introduce a new android_mallopt option to be able to query profileability of the process (which is now used by the new profiler signal handler). As part of that, gZygoteChildProfileable is moved from heapprofd_malloc to common (alongside gZygoteChild). I've removed the masking and reraising of the heapprofd signal when racing against malloc_limit init. We're ok with taking a simpler approach and dropping the heapprofd signal in such an unlikely race. Note: this requires a corresponding change in heapprofd to use sigqueue() instead of kill(), as the latter leaves the si_value uninitialized(?) on the receiving side.

Add a platform API for setting an allocation limit. Introduce an M_SET_ALLOCATION_LIMIT enumerator for android_mallopt(), which can be used to set an upper bound on the total size of all allocations made using the memory allocation APIs. This is useful for programs such as audioextractor and mediaserver which need to set such a limit as a security mitigation. Currently these programs are using setrlimit(RLIMIT_AS) which isn't exactly what these programs want to control. RLIMIT_AS is also problematic under sanitizers which allocate large amounts of address space as shadow memory, and is especially problematic under shadow call stack, which requires 16MB of address space per thread. Add new unit tests for bionic. Add new unit tests for malloc debug that verify that when the limit is enabled, malloc debug still functions for nearly every allocation function.

Add a platform API for setting an allocation limit. Introduce an M_SET_ALLOCATION_LIMIT enumerator for android_mallopt(), which can be used to set an upper bound on the total size of all allocations made using the memory allocation APIs. This is useful for programs such as audioextractor and mediaserver which need to set such a limit as a security mitigation. Currently these programs are using setrlimit(RLIMIT_AS) which isn't exactly what these programs want to control. RLIMIT_AS is also problematic under sanitizers which allocate large amounts of address space as shadow memory, and is especially problematic under shadow call stack, which requires 16MB of address space per thread. Add new unit tests for bionic. Add new unit tests for malloc debug that verify that when the limit is enabled, malloc debug still functions for nearly every allocation function.

Introduce hwasan mode for linker This mode instructs the linker to search for libraries in hwasan subdirectories of all library search paths. This is set up to contain a hwasan-enabled copy of libc, which is needed for HWASan programs to operate.

Make it easy to switch between scudo and jemalloc. Refactor some of the definitions to separate out all of the native allocator pieces into one place that can be changed easily. This should fix a few static libraries that appear to have accidentally included jemalloc wrapper functions. For example, I verified that libc_nomalloc.a no longer has references to any je_XXX functions. Modify the bionic_libc_platform_headers to not include any libraries. If this isn't updated, soong thinks there are cycles when used by libscudo. To enable scudo, change the libc_native_allocator_defaults defaults from libc_jemalloc5_defaults to libc_scudo_defaults and comment out the defaults: ["libc_scudo_wrapper_defaults"], line for the shared library libc_scudo. To do a final switch to scudo, it will be necessary to clean up some code in other parts of the tree, but this allows a single cl to enable or disable.

[GWP-ASan] Integrate GWP-ASan into bionc's malloc() (using hooks). This patch introduces GWP-ASan - a sampled allocator framework that finds use-after-free and heap-buffer-overflow bugs in production environments. GWP-ASan is being introduced in an always-disabled mode. This means that GWP-ASan will be permanently disabled until a further patch turns on support. As such, there should be no visible functional change for the time being. GWP-ASan requires -fno-emulated-tls wherever it's linked from. We intentionally link GWP-ASan into libc so that it's part of the initial set of libraries, and thus has static TLS storage (so we can use Initial-Exec TLS instead of Global-Dynamic). As a benefit, this reduces overhead for a sampled process. GWP-ASan is always initialised via. a call to mallopt(M_INITIALIZE_GWP_ASAN, which must be done before a process is multithreaded). More information about GWP-ASan can be found in the upstream documentation: http://llvm.org/docs/GwpAsan.html Bug: 135634846 Test: atest bionic Change-Id: Ib9bd33337d17dab39ac32f4536bff71bd23498b0

Add the recoverable GWP-ASan feature. GWP-ASan's recoverable mode was landed upstream in https://reviews.llvm.org/D140173. This mode allows for a use-after-free or a buffer-overflow bug to be detected by GWP-ASan, a crash report dumped, but then GWP-ASan (through the preCrashReport() and postCrashReportRecoverableOnly() hooks) will patch up the memory so that the process can continue, in spite of the memory safety bug. This is desirable, as it allows us to consider migrating non-system apps from opt-in GWP-ASan to opt-out GWP-ASan. The major concern was "if we make it opt-out, then bad apps will start crashing". If we don't crash, problem solved :). Obviously, we'll need to do this with an amount of process sampling to mitigate against the 70KiB memory overhead. The biggest problem is that the debuggerd signal handler isn't the first signal handler for apps, it's the sigchain handler inside of libart. Clearly, the sigchain handler needs to ask us whether the crash is GWP-ASan's fault, and if so, please patch up the allocator. Because of linker namespace restrictions, libart can't directly ask the linker (which is where debuggerd lies), so we provide a proxy function in libc. Test: Build the platform, run sanitizer-status and various test apps with recoverable gwp-asan. Assert that it doesn't crash, and we get a debuggerd report.

Move dl_unwind_find_exidx from libdl.a to libc.a arm32 has two special APIs to find exidx exception handling info, dl_unwind_find_exidx and __gnu_Unwind_Find_exdix. The two functions have identical behavior and function prototypes. libgcc's arm32 unwinder calls __gnu_Unwind_Find_exdix, whereas LLVM's libunwind previously called __gnu_Unwind_Find_exdix, but switched to dl_unwind_find_exidx as a result of three patches (D30306, D30681, D39468). In Bionic, for dynamic linking, __gnu_Unwind_Find_exdix in libc.so calls dl_unwind_find_exidx in libdl.so. For static executables, though, __gnu_Unwind_Find_exdix in libc.a used the __exidx_* symbols, while dl_unwind_find_exidx in libdl.a(libdl_static.o) was a return-0 no-op. To fix the LLVM unwinder, replace the no-op dl_unwind_find_exidx in libdl.a with a real function in libc.a(exidx_static.o), and have the GNU function call the dl function for more consistency with dynamic linking. dl_iterate_phdr follows a similar pattern, where the function exists in libc.a and libdl.so (not libc.so or libdl.a). This change makes unwinding work with an updated libunwind_llvm on arm32, and it helps to allow unwinding in static executables without libdl.a.

Load libc_malloc_* libraries from the runtime APEX /system/lib/libc.so is a symlink to libc.so in the runtime APEX. libc_malloc_* libraries are bundled with libc.so because they share implementation details. However, since libc.so is loaded in the default namespace where the runtime APEX path (/apex/com.android.runtime/lib) is not accessible, libc.so has been using libc_malloc_* from /system/lib. This is wrong because libc.so (from the runtime APEX) and libc_malloc_* (from the platform) may not be in-sync. libc.so now uses android_dlopen_ext to load libc_malloc_* libraries correctly from the "runtime" linker namespace.

Otherwise, platform could break when a symbol is removed from the libs via the APEX update. To achive this goal, this change adds stubs variant to the bionic libs. With this, things outside of the runtime APEX (i.e. other APEXes and the platform) are built with the stubs variants that provide only the symbols that are guaranteed to be stable. The set of symbols are basically the same as the symbols available to NDK clients. However, there are a few additional symbols that are not available for NDK but should be made available for platform components. They are marked with "# apex" tag. Symbols with that tag are not exposed to apps (via NDK stubs) or vendors (via LLNDK stubs). Note that the stubs is a build-time only artifact.

Add a tool to track down fd leaks. Add a hook that's called upon file descriptor creation to libc, and a library that uses it to capture backtraces for file descriptor creation, to make it easier to hunt down file descriptor leaks. Currently, this doesn't capture all of the ways of creating a file descriptor, but completeness isn't required for this to be useful as long as leaked file descriptors are created with a function that is tracked. The primary unhandled case is binder, which receives file descriptors as a payload in a not-trivially-parsable byte blob, but there's a chance that the leak we're currently trying to track down isn't of a file descriptor received over binder, so leave that for later.

Make it easy to switch between scudo and jemalloc. Refactor some of the definitions to separate out all of the native allocator pieces into one place that can be changed easily. This should fix a few static libraries that appear to have accidentally included jemalloc wrapper functions. For example, I verified that libc_nomalloc.a no longer has references to any je_XXX functions. Modify the bionic_libc_platform_headers to not include any libraries. If this isn't updated, soong thinks there are cycles when used by libscudo. To enable scudo, change the libc_native_allocator_defaults defaults from libc_jemalloc5_defaults to libc_scudo_defaults and comment out the defaults: ["libc_scudo_wrapper_defaults"], line for the shared library libc_scudo. To do a final switch to scudo, it will be necessary to clean up some code in other parts of the tree, but this allows a single cl to enable or disable. Bug: 137795072 Test: Builds with jemalloc or scudo with a small change. Test: Ran bionic unit tests.

libc_header is available to any apex but only visible to certain places The header library is used by some libraries, such as libunwind_llvm, which are automatically added as dependencies when stl is set to libc++_static. Since such dependencies are not specificy to any APEX, let's mark the header library be available (can be directly or indirectly be part of an APEX) to any APEX. At the same time, limit the visibility of the header library so that its uses are strictly limited to the certain places that we acknowledge. (the places would be reduced further when we will be successful in dropping the dependency to libc_headers.) Bug: 152668052 Test: m Change-Id: I85ee900947df2c9ce076e2f3aa3145645da77d2b

Export the unwinder implementation from libc. This supports the soong commit which causes most platform binaries to stop statically linking against the unwinder implementation. The soong commit message has more motivation for this change. ARM32 uses LLVM libunwind, while all other platforms use libgcc as the unwinder implementation. This matches the current choices of unwinders on the various architectures, but means that apps which were directly linking against the libc.so unwinder symbols on ARM32 are now using LLVM libunwind instead of libgcc. Set libc_headers sdk_version to 1 so that libunwind_llvm can depend on it, and stop statically linking libunwind into libc_malloc_debug.

Optimize libc for generic armv7/armv8 neon cores If (2nd) arch is "arm", (2nd) arch variant is "armv7-a-neon" or "armv8-a", and (2nd) cpu variant is "generic", current Android.bp only uses generic ARM assmebly or C code, even though they all have NEON. This change use functions optimized for cortex-a15 (for these generic cores), which are a reasonable balance for most ARM cores with Neon. Also build script for specific armv7/armv8 cores are refactored to take advantage of the common part (mostly cortex-a15 code), so more than 150 repeated lines are removed. Bug: 66064745 Test: For armv7-a-neon/armv8-a "generic" core - boot with GSI on sailfish - related cortex-a15 function are built and linked.

Reuse the libm scalbn() as ldexp(). These are the same function for machines with binary floats (that is: all machines), but ldexp() is in libc rather than libm, so we can't just use an alias. We were using this duplicate copy of the code, but upstream FreeBSD has removed it, and I'd prefer to do the same. Longer term, we should just move all of libm into libc (but keep an empty libm for compatibility), but this is probably easier for now.

Prevent dependency cycle due to system_shared_libs expansion It was discovered that we were building some objects inconsistently due to an optimization in cc_library to only build objects once and use them for both the static and shared libraries. But static libraries didn't get system_shared_libs set automatically, and we didn't notice that we would have built the objects differently. So static libraries now get the default system_shared_libs, we allow adjusting that for static vs shared in a cc_library, and we disable the optimization if the linked libraries are configured differently between static and shared in a single cc_library. This triggers dependency cycles for static libraries that libc/libdl use, so fix those cycles here. Test: treehugger Change-Id: I3cf7fda161a05ec32e0c1e871999720d12a4d38e

Disable sanitization of crt objects. The accompanying soong change causes sanitize attributes to be allowed on cc_object targets and propagates sanitize attributes into dependencies. This is problematic for the crt objects in sanitizer builds because everything depends on them including the sanitizer runtime, so a circular dependency would otherwise be created. Furthermore, some of the code in these objects runs before sanitizer initialization so it is unlikely that sanitizing them would work anyway. Therefore, disable sanitization on these objects.

Let executables not rely on sentinels in preinit_array/init_array/fini_array Currently, we use sentinels (starting with -1 and ending with 0) in preinit_array/init_array/fini_array in executables. But after using LTO, the sentinels can be reordered by LLD and no longer work. So make below changes to not rely on them: 1. In crtbegin.c, use symbols (like __init_array_start) inserted by the linker. 2. Add array_count fields in structors_array_t. 3. In static libc, use array_count fields to decide array lengths. 4. To make new dynamic executables work with old libc.so, create a fake fini_array with sentinels, and pass it to __libc_init. The fake fini_array contains a function to call functions in real fini_array. 5. To make old dynamic executables work with new libc.so, libc.so still uses sentinels to decide the length of fini_array.

crtbegin_static is built with min_sdk_version: "current" crtbegin_static is used by static exectuables which are guaranteed to be with the latest library regardless of their target API level. This change is in fact not a regression as crtbegin_static has been built with __ANDROID_API__=10000 before I645e6bb1234c27ae0a69b7b87a59206cfd350744 when __ANDROID_API__ tracked sdk_version, not min_sdk_version. sdk_version was not set for crtbegin_* objects and therefore the default "current" was (incorrectly) used. With this change, we are recovering the original behavior for the static variant, while the building of the dynamic variant becomes more correct - it's now with __ANDROID_API__=16. Without this change, several static executables fail to build as 1) crtbegin_static for them is built with __ANDROID_API__=16 and 2) libc_init_common.cpp uses pthread_atfork which is available only after API level 23. We hit undefined symbol error when linking. Bug: 134795810 Test: m Change-Id: I1430e57302951df33530ea0ae91b0d7a0609bf3d

Merge crt cc_objects Currently there is a pattern of `crtbegin_${type}1` and `crtbegin_${type}` modules, where the former has sources and the latter depends on the former. The two modules for a type share many properties, rather than duplicating these, we merge modules, such that each type only has a `crtbegin_${type}` module.

Use an embedded linker for host bionic The linux kernel requires that the ELF interpreter (runtime linker) that's referenced by PT_INTERP be either an absolute path, or a relative path from the current working directory. We'd prefer a relative path from the binary, similarly to how we handle looking up shared libraries, but that's not supported. Instead, extract the LOAD segments from the runtime linker ELF binary and embed them into each host bionic binary, omitting the PT_INTERP declaration. The kernel will treat it as a static binary, and we'll use a special entry point (linker_wrapper) to fix up the arguments passed by the kernel before jumping to the embedded linker. From the linker's point of view, it looks like the kernel loaded the linker like normal.

genfunctosyscallnrs: maps bionic functions to syscall numbers. Bionic maps typical C functions like setresuid() to a syscall, depending on the architecture used. This tool generates a .h file that maps all bionic functions in SYSCALLS.txt to the syscall number used on a particular architecture. It can then be used to generate correct seccomp policy at runtime. Example output in func_to_syscall_nrs.h: Bug: 111434506 Test: manually inspect func_to_syscall_nrs.h Change-Id: I8bc5c1cb17a2e7b5c534b2e0496411f2d419ad86

riscv64 syscall stub and seccomp filter generation. These are sufficiently intertwined that they need to be done together. riscv64 is our first primary-only architecture, so that required some changes. The .bp changes are to support this --- we need to only show the python scripts the architectures they'll actually be using, rather than showing them everything and ignoring some of the results. riscv64 is also the first architecture that post-dates the kernel's 64-bit time work, so there's a bit of extra fiddling needed to handle the __NR3264_ indirection in the uapi headers.

Create a lib that uses scudo instead of jemalloc. The media processes already use scudo as their allocator. However, it doesn't really correctly replace the normal allocation functions, so create a set of wrappers that allow us to use scudo closer to how jemalloc is used. This is only a temporary change, and should be removed for the next release of Android. In that version, we will be using standalone scudo which won't require this wrapper code. Bug: 123689570 Test: Ran new bionic unit tests. There are failures, but only with Test: extensions that scudo does not support. Change-Id: I0516c23d654a9b6c69b157c5501245d2e0b3d264

Export fts as a static library for use with musl musl libc doesn't provide fts, but elfutils and libabigail need it. Export bionic's fts as a staic library that can be linked into elfutils and libabigail when compiling against musl. fts uses recallocarray, which musl doesn't provide, so also include recallocarray.c in libfts.a. Requires minor tweaks to fts.c and a wrapper around fts.h to make them compatible with musl, primarily by providing local definitions of macros provided in bionic's sys/cdefs.h.

Export bionic's fts as a staic library that can be linked into elfutils and libabigail when compiling against musl. fts uses recallocarray, which musl doesn't provide, so also include recallocarray.c in libfts.a. Requires minor tweaks to fts.c and a wrapper around fts.h to make them compatible with musl, primarily by providing local definitions of macros provided in bionic's sys/cdefs.h.

Create a filegroup for versioner dependencies As part of the build, soong runs the following cmd ``` $ versioner -o <out_dir> bionic/libc/include bionic/libc/versioner-dependencies ``` To migrate this action to Bazel, create a filegroup module for `bionic/libc/versioner-dependencies`. In Bazel builds, this target will be copied to the Bazel's sandbox and placed on the include path when running versioner. This should be a no-op in Soong. `bionic/libc/versioner-dependencies` is a collection of symlinks, some of which point to `prebuilts/clang-tools`.
