Bug #: 13113
Summary: issues with libc being loaded twice when using audit
library
Product: glibc
Version: 2.14
Status: NEW
Severity: normal
Priority: P2
Component: libc
AssignedTo: drepper.fsp@gmail.com
ReportedBy: jolsa@redhat.com
Classification: Unclassified
When running binary with audit library, the libc shared library is loaded
twice within the process.
It appears thats one time for binary namespace binary and second in namespace
for audit library. This is probably intended, not sure..
However this gets me to the dead end when I unwind stack from within
the audit library. The dl-iterate function gets me only libraries
from audit namespace.
And when I hit a function address from within the libc library loaded for
the binary I'm stuck, since I dont have any information about this library.
(eh_frame/debug_frame info).
So I'm not sure what should be fixed here..
* having 2 libc libraries loaded at the same time
* having dl-iterate to return info about all namespaces
* me ;)
please let me know if I can give you any other info/test/debug..
thanks for any ideas
