* Change the 64 bit map address format.Christopher Ferris2015-06-031-10/+27
| | | | | | | | | | | | | | | | Previously, the map printing in tombstones for 64 bit devices uses a variable length value. This means that the maps are not lined up. The new format is to print the map as 00000000'00000000 in all ways. Also fix a bug where the backtrace_map_t did not initialize all parameters. Add unit tests for all of the dump_all_maps function. Bug: 20950813 (cherry picked from commit 862fe029190b6d8344889988fb85526e64b2f4b7) Change-Id: Ife5c48bddeb19006a98f9e87520474e97b97f6d9

* Prevent crashes if a map cannot be created.Christopher Ferris2015-05-151-1/+7
| | | | | | | | | | | | | | | Under some conditions, /proc/<pid>/maps might return nothing. If we try and unwind in this case, we'll crash. Check this case and fail the unwind. Add checks that no other functions try and use map_ without checking for nullptr. Add logging when an unwind fails so it's clear what happened.

* Add load base to map for relocation packing.Christopher Ferris2015-05-011-0/+3
| | | | | | | | | | The new linker relocation packing support uses non-zero load bases, so we better handle them properly. Also print out the load base for a map if it's non-zero. Bug: 20687795 Change-Id: Iec2d1db2051e7b4a278c1dfa57d745128a7f2974
* Print the build id of shared libraries if present.Christopher Ferris2015-03-171-60/+81
| | | | | | | | | | | | For every map that has a name, and if it's a mapped in shared library, print the build id. Refactor the way dump_all_maps logs data. Refactor the way stack segments are dumped. Bug: 19371018 Change-Id: Ic08d05a4b13f128925743936fb84d8059f7cb56f
* liblog: introduce ANDROID_LOG_* flagsMark Salyzyn2015-02-251-1/+1
| | | | | | | | Move away from using POSIX open(2) flags and introduce ANDROID_LOG_* flags to replace them. Add security by preventing random mode flags from getting into underlying POSIX calls. ANDROID_LOG_* flags overlap POSIX O_* flag definitions. Change-Id: Ib32bb64c287e8bf150be62242e1ba46bb37839fc
* Do not dump maps/memory/code of sibling threads.Christopher Ferris2015-02-091-43/+39
| | | | | | | | | | | | | | | Modifies the code so that if the unwind fails, the code still prints as much data as possible. Also, for sibling threads, skip printing the maps and memory/code since it's not likely to be very relevant. Fix a few cases where extra space is at the end of lines. Fix an inverted if statement that was checking the wrong condition. Bug: 18816322 Change-Id: Ic659e0c34489bf2c65c5a23e2b83e31653b927e4
* Move map data into backtrace data proper.Christopher Ferris2015-02-061-3/+4
| | | | | | | | | | | The backtrace structure used to include a pointer to a backtrace_map_t that represented the map data for a particular pc. This introduced a race condition where the pointer could be discarded, but the backtrace structure still contained a pointer to garbage memory. Now all of the map information is right in the structure. Bug: 19028453 Change-Id: If7088a73f3c6bf1f3bc8cdd2bb4b62e7cab831c0

* Improving maps output.Brigid Smith2014-07-081-15/+19
| | | | | | | | | | | | | | | Maps output now displays fault address location more intelligently. If the fault is not in a mapped region, it now shows where that address is with respect to the other maps. In addition, the size of the map is now printed as part of the output. Also, crasher now supports an "mmap" option which mmaps/munmaps a region of memory and then attempts to access it, causing a fault address in between mapped regions that can be used to test that new part of the maps output.

| | | | | | PID and TID output line was missing. Change-Id: I609af5727bc22ea0b97f3975ddb3cf0102910bc2
* Maps output now marks the fault address location.Brigid Smith2014-06-201-4/+13
| | | | | | | | If the fault address is not within a mapped region, it logs an error message after the output. Otherwise, it prefixes the location of the fault address with "--->" to make it easier to locate. Change-Id: I330adaade4402ffeb09f1a6d34a944c2f054d06d
* Removed log.quiet and log = NULL cases from debuggerd.Brigid Smith2014-06-191-16/+15
| | | | | | | | | Now the functionality implemented by these semi-confusing cases has been replaced with the same logtype enum behavior that is easier to understand, and cases that used log-looking behavior to print to logcat (when log = NULL) now use the more transparent ALOGE/ALOGD functions. Change-Id: I7e38f2d4ca74a828df4d2266b3ea34edd3c6f5bb
* Changed maps output in debuggerd.Brigid Smith2014-06-171-28/+4
| | | | | | | | | | | Now the map output is only sent to the tombstone, and the entire contents of /prod/$PID/maps is logged, not just 3 lines. Additionally, crasher now supports "crasher SIGSEGV-non-null", which attempts to write to a dereferenced function address, causing a SIGSEGV at a non-zero address. This new crasher mode can be used to test the new maps output. Bug: 15343662 Change-Id: I796d92e8352a6b9714bbbfe96f3143c56565ef2f
* Changing how debuggerd filters log messages to different locations.Brigid Smith2014-06-161-79/+84
| | | | | | | | | | | | | The system by which debuggerd filters its output to different locations is now based on an enum called logtype with easy to understand categories for log messages (like THREAD, MEMORY, etc.) instead of the old, fairly esoteric scope_flags variable. Now much of the output that previously went to logcat does not show up on the screen, but all output can be found in the tombstone file. In addition, the tombstone's location is now printed so it can be located easily. Bug: 15341747 Change-Id: Ia2f2051d1dfdea934d0e6ed220f24345e35ba6a2

* Use the si_code value bionic passes us.Elliott Hughes2014-04-251-20/+27
| | | | | | | | | Bionic needs to re-raise various signals, which means the si_code debuggerd sees has been clobbered. If bionic sends us the original si_code value, we can use that instead of the one we see when the ptrace the crashed process' siginfo. Change-Id: If116a6bc667d55a6fb39b74f96673292af4e4c8c
