Description: Test for bz566712 (If pthread_create fails in aio_write, requests)
|
|
Author: Petr Muller <pmuller@redhat.com>
|
|
Bug summary: If pthread_create fails in aio_write, requests linked list is corrupted
|
|
Bugzilla link: https://bugzilla.redhat.com/show_bug.cgi?id=566712
|
|
|
|
Description:
|
|
|
|
Description of problem:
|
|
When one calls aio_write, it internally calls __aio_enqueue_request, which will in turn call aio_create_helper_thread. If thread creation fails, the newly created request (newp in the code) will still be in the requests linked list, but it will be freed later in __aio_enqueue_request.
|
|
|
|
A subsequent call to aio_write will cause a segmentation fault.
|
|
|
|
Version-Release number of selected component (if applicable):
