2017-05-11crash-stack: Change "ThreadID" heuristic to work on aarch64Karol Lewandowski1-1/+1
Commit 82e3caa86 ("crash-stack: Find crashed tid by wchan") introduced heuristic method of finding correct thread id, if it was not passed by the kernel as parameter to crash-manager. This commit modifies this heuristic to also consider "pipe_wait" function in kernel to signify crashed thread. This is what was observed to be true on aarch64.

2017-04-14crash-stack: Eliminate now-deprecated readdir_rKarol Lewandowski1-6/+5
This commit fixes build break with new toolchain. Glibc 2.24 deprecated readdir_r() - readdir() now recommended even for multithreaded programs. This commit fixes following error: /home/abuild/rpmbuild/BUILD/crash-worker-1.0.0/src/crash-stack/crash-stack.c: In function 'find_crash_tid': /home/abuild/rpmbuild/BUILD/crash-worker-1.0.0/src/crash-stack/crash-stack.c:891:4: error: 'readdir_r' is deprecated [-Werror=deprecated-declarations] while (readdir_r(dir, &entry, &dentry) == 0 && dentry) { ^~~~~ Change-Id: I99f22a0de87f2539988e1669ae2149dcac74a4df

2017-02-20crash-stack: Get executable name from cmdlineSunmin Lee1-3/+11
The executable name in crash-stack is different with sys-assert. In case of some applications, "exe" has indicated real path of app that makes it hard to know what the actual app name is. It's better to refer to "cmdline" instead. Change-Id: I4895dbce427d50cd20a593585f2640554a4268fc Signed-off-by: Sunmin Lee <sunm.lee@samsung.com>

Some information had lost after ptrace. However, the order of info also should be preserved. To resolve this, that information are going to be printed to temporal space first and will be merged in result file.

2017-02-02crash-stack: disable unw_get_proc_name predictionRafal Pietruch1-6/+2
libunwind unw_get_proc_name function may return the name of a label or a preceeding, nearby procedure; although the value of the returned name plus the returned offset will be equal to the instruction-pointer of the stack frame, developers can find a exact symbol with related code position in debug packages Change-Id: I2471c2a9483b577844110f25128a6d539d39e5ad

It is hard to get signal info which caused dump using ptrace. Therefore, crash-stack prints signal number only which came from core_pattern. Change-Id: I6cd865a89d3e2c5dd83cfe134bb8cddec4f7f81f Signed-off-by: Sunmin Lee <sunm.lee@samsung.com>

2016-12-20crash-stack: fixed attaching to threadAdrian Szyndela1-28/+23
It is not necessary to attach to parent process main thread to resolve stack in another thread. This commit also solves hanging up on 'D' (and 'Z') processes - main thread is not attachable, when a crash occurs in another thread. Change-Id: Ic3a085951acb4057fcdd4a476693954d1d3a522b
2016-12-20crash-stack: deprecate corefile optionSunmin Lee1-249/+10

2016-12-15crash-stack: work around hanging up on 'D' processesAdrian Szyndela1-0/+72
Processes in uninterruptible sleep state ('D' status in ps) cannot be ptraced until they leave the state. To prevent hanging up of crash-stack, we check the target process state. If it is 'D', then we give up ptracing it, and instead print the information from /proc/<pid>/wchan, /proc/<pid>/syscall and /proc/<pid>/stack. Change-Id: I82644051a5499c42db2a8e51a7af98693e8da363

2016-12-14crash-stack: put more effort into getting namesAdrian Szyndela1-104/+93
It seems libdwfl-0.153 sometimes can't get symbol names automatically. This commit adds fallback procedure, that takes module name and mapping provided by libdwfl, and - using libelf - looks for the symbol name, instead of relying only on libdwfl.
