2020-11-11Add "product_available" to product available modulesJustin Yun
"vendor_available" modules were available to product modules. However, not all "vendor_available" modules are required to be available to product modules. Some modules want to be available only to product modules but not vendor modules. To cover the requirement, we separate "product_available" from "vendor_available". "vendor_available" will not provide product available module. Bug: 150902910 Test: build Change-Id: I13b8222e191333c6c2cb7794ef3344fdcc6ebe98

2020-08-21async_safe: don't call libc's socket.Josh Gao
Like with close, socket is no longer a simple syscall, so we can get recursive calls that deadlock. Bug: http://b/165206592 Test: bionic-unit-tests on cuttlefish Test: treehugger Change-Id: I2ba77d733d1ebf08a91afd6ca179e7ae6ae3866e
2020-06-10linker: CHECK() or async_safe_fatal() rather than abort().Elliott Hughes
In particular, add the strerror() output if mprotect() fails. Fix the CHECK macro so that you can make assertions involving operator% without that being confused for a printf format specifier.

2019-02-14libasync_safe: stop clobbering other folks' identifiers.Elliott Hughes
The log priorities and ids are in an NDK header, available to everyone. Move CHECK into its own header for now. This would be better if it was more like the <android-base/logging.h> CHECK family, but I don't have an easy way to do that without lots of copy & paste, so punting for now.

2019-01-19Add libc_headers header libLogan Chien
This commit extracts `libc_headers` for `libasync_safe` and `libpropertyinfoparser` (in the `system/core` repository). Before this change, `libasync_safe` expects that `libc` is automatically added to `system_shared_libs` of the libasync_safe vendor variant even if `libc_defaults` explicitly declines any `system_shared_libs`. This commit defines `libc_headers` for `libasync_safe` and `libpropertyinfoparser` so that they can find the headers from libc without causing circular dependencies.

2018-06-08Build recovery variant of the dynamic linkerJiyong Park
In order to support shared libraries in the recovery mode, the dynamic linker is now built with recovery_available: true option. In addition, a few more modules (such as libasync, etc.) are also marked as recovery_available: true as they are transitive dependencies of the dynamic linker. Bug: 63673171 Test: `adb reboot recovery; adb devices` shows the device ID Test: `adb root && adb shell` and then $ lsof -p `pidof adbd` shows that libm.so, libc.so, etc. are loaded from the /lib directory.

2017-10-25Implement pthread_attr_getinheritsched/pthread_attr_setinheritsched.Elliott Hughes
Historically, Android defaulted to EXPLICIT but with a special case because SCHED_NORMAL/priority 0 was awkward. Because the code couldn't actually tell whether SCHED_NORMAL/priority 0 was a genuine attempt to explicitly set those attributes (because the parent thread is SCHED_FIFO, say) or just because the pthread_attr_t was left at its defaults. Now we support INHERIT, we could call sched_getscheduler to see whether we actually need to call sched_setscheduler, but since the major cost is the fixed syscall overhead, we may as well just conservatively call sched_setscheduler and let the kernel decide whether it's a no-op. (Especially because we'd then have to add both sched_getscheduler and sched_setscheduler to any seccomp filter.) Platform code (or app code that only needs to support >= P) can actually add a call to pthread_attr_setinheritsched to say that they just want to inherit (if they know that none of their threads actually mess with scheduler attributes at all), which will save them a sched_setscheduler call except in the doubly-special case of SCHED_RESET_ON_FORK (which we do handle). An alternative would be "make pthread_attr_setschedparams and pthread_attr_setschedprio set EXPLICIT and change the platform default to INHERIT", but even though I can only think of weird pathological examples where anyone would notice that change, that behavior -- of pthread_attr_setschedparams/pthread_attr_setschedprio overriding an earlier call to pthread_attr_setinheritsched -- isn't allowed by POSIX (whereas defaulting to EXPLICIT is). If we have a lot of trouble with this change in the app compatibility testing phase, though, we'll want to reconsider this decision! -*- This change also removes a comment about setting the scheduler attributes in main_thread because we'd have to actually keep them up to date, and it's not clear that doing so would be worth the trouble. Also make async_safe_format_log preserve errno so we don't have to be so careful around it. Bug: http://b/67471710 Test: ran tests Change-Id: Idd026c4ce78a536656adcb57aa2e7b2c616eeddf

2017-09-19Improve pthread_create failure handling.Elliott Hughes
Return EAGAIN rather than aborting if we fail to set up the TLS for a new thread. Add a test that uses all the VMAs so we can properly test these edge cases. Add an explicit test for pthread_attr_setdetachstate, which we use in the previous test, but other than that has no tests. Remove support for ro.logd.timestamp/persist.logd.timestamp, which doesn't seem to be used, and which prevents us from logging failures in cases where mmap fails (because we need to mmap in the system property implementation).

2017-06-20Shave a stack frame off asserts.Elliott Hughes
No-one cares about seeing "async_safe_fatal" (which you have to admit is a pretty confusing name for an app developer anyway).

2017-06-14make libasync_safe vendor_available:trueJiyong Park
This, when used with BOARD_VNDK_VERSION flag, enables the module to be built and installed twice, one for /system, other for /vendor. libasync_safe is used by libbacktrace which is in turn used by libs in /vendor and thus marked as vendor_available. Therefore, libasync_safe is also marked as vendor_available.

2017-05-03Move libc_log code into libasync_safe.Christopher Ferris
This library is used by a number of different libraries in the system. Make it easy for platform libraries to use this library and create an actual exported include file. Change the names of the functions to reflect the new name of the library. Run clang_format on the async_safe_log.cpp file since the formatting is all over the place. Bug: 31919199 Test: Compiled for angler/bullhead, and booted. Test: Ran bionic unit tests. Test: Ran the malloc debug tests. Change-Id: I8071bf690c17b0ea3bc8dc5749cdd5b6ad58478a
