| * Fix debuggerd issues.Christopher Ferris2014-11-035-63/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Fix a problem where a tid exits before the attach completes, and it causes debuggerd to self terminate. - Fix a problem where sibling tid dumps do not properly wait for the tid to get signalled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | debuggerd allows uid-0 processes to dump tombstones or backtraces of any process, and uid-system processes to dump backtraces of any processes. Restrict these operations via SELinux based on the client context, the target process context, and the action.

* Improving maps output.Brigid Smith2014-07-082-15/+25
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | Now the debugging output shows the tid of the crashed thread instead of the pid of the process that crashed. Change-Id: I637f409ff02d73d458edc6d1a5c462c21d128211

* Fixed pathname for connecting to debugger.Brigid Smith2014-06-241-11/+1
| | | | | | | The debug output was still showing the pathname that worked with gdbclient before my changes, and therefore did not work after the fact. Change-Id: Ie12d79f5346088914ce0a70bda69780707b31d31

* 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 Smith2014-06-196-81/+69
| | | | | | | | | 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.

* Changed maps output in debuggerd.Brigid Smith2014-06-172-29/+13
| | | | | | | | | | | 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 Smith2014-06-1612-261/+263
| | | | | | | | | | | | | 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
