+++ This bug was initially created as a clone of Bug #285761 +++ Backport of the Rawhide Bug for FC-6. Description of problem: I trace a process using ptrace and the PTRACE_O_TRACEEXIT option. When I get the PTRACE_EVENT_EXIT notification for the process I examine its memory mappings by reading /proc/<pid>/maps. This works on vanilla Linux kernels. On the Fedora kernel this works if the process exited normally, but if it was killed by a signal I get EACCES when trying to open /proc/<pid>/maps. I guess this is undocumented behaviour, but it would be good to know if I should expect a fix or work around the problem somehow. I am running the x86_64 version of the kernel on a Core 2 T7200. Version-Release number of selected component (if applicable): kernel-2.6.22.7-57.fc6.x86_64 How reproducible: Every time. Steps to Reproduce: 1. Compile and run the attached test case. Actual results: Test case fails to open /proc/<pid>/maps. Expected results: Test case prints the contents of /proc/<pid>/maps.
Created attachment 211161 [details] Testcase.
(This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora!
Per the previous comment in this bug, I am closing it as INSUFFICIENT_DATA, since no information has been lodged for over 30 days. Please re-open this bug or file a new one if you can provide the requested data, and thanks for filing the original report!
