            Bug ID: 30619
           Summary: Support dlopen after multi-threaded fork in more cases
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dynamic-link
          Assignee: unassigned at sourceware dot org
          Reporter: fweimer at redhat dot com
  Target Milestone: ---

The dlopen function is used internally in various places (backtrace, iconv,
pthread_exit, NSS). It would be preferable if it worked after a multi-threa=
ded
fork.

Right now, we get various hangs, or an assertion failure:

Inconsistency detected by ld.so: dl-open.c: 583: dl_open_worker_begin:
Assertion `r_state =3D=3D RT_CONSISTENT' failed!

Bug 24941 is an example of a surprising use of NSS. There might be others.
