2020-10-16Remove libprocinfo, libbacktrace, libunwindstackBaligh Uddin
These projects have moved to a different location. platform/system/core [libprocinfo] -> platform/system/libprocinfo platform/system/core [libbacktrace] -> platform/system/unwinding [libbacktrace] platform/system/core [libunwindstack] -> platform/system/unwinding [libunwindstack] BUG: 163786882 Test: Local build + TH Change-Id: Id6d278d917236df0ffd40b5c32593856e112cb5b
2019-06-11Internalize subclasses of MemoryCasey Dahlin
There are many subclasses of the Memory class and the overwhelming majority of them don't need to be exposed externally. We move all of them to internal headers except MemoryOfflineBuffer, which moves to a separate header. This dramatically reduces the exposed API surface and makes the code more modular. Also, remove the Offline code from libbacktrace. It's not used any where. Test: Unit tests pass, clean tree still builds Change-Id: I55dacdf080daba0bfe65c1ad53a4b326bb482e83
2018-10-03Implement support for linker rosegment option.Christopher Ferris
The rosegment linker option results in two maps containing the elf data existing. One is an execute map where the code lives, and the other is the read-only segment which contains the elf header information. If the file backing a shared library in memory is not readable, then the new code will attempt to find the read-only map that has the same name as the current execute segment, and that is at offest zero in the file. Add new unit tests for this functionality. Add the missing MapInfoCreateMemoryTest.cpp to the list of tests. Bug: 109657296 Test: Pass new unit tests. Test: All unit libbacktrace/libunwindstack tests pass with rosegment enabled. Change-Id: If8f69e4a067d77b3f2a7c31e2e5cd989a0702a8c
2017-11-15unwindstack: rename Memory::ReadPartially to Read.Josh Gao
Test: mma Test: treehugger Change-Id: I53c2c5600fb44620b629c01db85a67789594595f
2017-11-15unwindstack: rename Memory::Read to ReadFully.Josh Gao
Rename Memory::Read to ReadFully to match its semantics with that of android::base. ReadPartially will be renamed to Read in a follow up commit, kept intentionally separate so that there aren't any callers accidentally switched from ReadFully to Read. Test: treehugger Change-Id: I7d845ac5244c3025d92c8512e960e5d0d1da05af
2017-11-15unwindstack: add Memory::ReadPartially.Josh Gao
Add a way to read while allowing for partial reads. Test: new tests added to libunwindstack_test, ran 32/64 on hikey960, sailfish Test: ran unwind on hikey960/sailfish Change-Id: I8b11d9230fcd3122148ef3f980863ac1404ad70a
2017-09-05Add a method to share the process memory object.Christopher Ferris
New function to create the process memory object. This allows for a future where different remote process memory objects could be created depending on the way remote memory can be created. Even different local memory objects that access memory without doing any checks. It also allows MemoryRange objects to share one single process memory object and could help if the process memory object caches data. Small changes to MapInfo::CreateMemory to when some errors are detected. - Always check if the map is a device map, instead of only if the name is not empty. - Check if a memory map is readable before creating the memory from process memory. Bug: 23762183 Test: Ran unit tests, unwound on device using the new code. Change-Id: I12a93c2dc19639689a528ec41c67bfac74d431b3
2017-07-14Make the library usable as a library.Christopher Ferris
- Add namespace unwindstack everywhere so that it's easier for other code to use the library. - Move some of the header files into include/unwindstack so that they can be exposed. - Modify the headers so that only a limited number need to be exposed. - Update the tools to use the new headers. - Add a GetLoadBias() call on the Elf object. This prevents the need to get the interface object out of the Elf object. - Move the GetRelPc() call out of the Reg class, to the Elf class. It's not always the case that a Reg object will be around when you want to get a relative pc. The tests for this moved to ElfTest.cpp. Bug: 23762183 Test: Unit tests pass.

2017-06-19Fix some memory leaks, potential errors.Christopher Ferris
Fix a couple of memory leaks in tests. Fix a potential case that length could be zero. Bug: 23762183 Test: Ran unit tests, then ran valgrind on unit tests and verified no leaks. Change-Id: I5f7602aa0204db0488a8e305250658cdb6e977d0
2017-04-03Add overflow checks in Memory objects.Christopher Ferris
Also change one of the reads to be explicitly ReadField instead of an overloaded Read function. Bug: 23762183 Test: Passes new unit tests. Change-Id: Id848f7b632f67df0c5b7318d9e588942cfd2099a
2017-03-09Elf interface for new unwinder.Christopher Ferris
This cl includes the code to read arm unwind information from a shared library. Bug: 23762183 Test: Passes all unit tests. I can dump the arm unwind information Test: for an arm shared library. Change-Id: I43501ea2eab843b81de8bd5128401dd1971af8d3
2017-01-25New version of unwinder.Christopher Ferris
Bug: 23762183 Test: All unit tests pass. Change-Id: I0ac69e55af56e1142c0a1ee3715cdc48f2ed3ec3
