2011-11-06pthread_getspecific, pthread_setspecific: check the key validityPino Toscano
When getting a TSD, handle gracefully the case of an invalid key. When setting a TSD, check for the validity of the key as recommended (although not required) by POSIX. This also avoids potentially filling the `thread_specifics' hash of threads with TSD of invalid keys. Add two simple checks in test-7.c for the two situations above. * sysdeps/hurd/pt-getspecific.c (pthread_getspecific): Check the validity of the specified key. * sysdeps/hurd/pt-setspecific.c (pthread_setspecific): Likewise. * tests/test-7.c (main): Add two assertions.

2011-11-05Remove all the values when deleting a keyPino Toscano
When deleting a key using `pthread_key_delete', delete all the values associated to that key in all the threads available. Otherwise, the key reuse in `pthread_key_create' can cause new keys to have thread specific data of the previously used key with the same index. Add a test for this case, which creates and deletes pairs of keys checking that they have a NULL thread specific data after creation. * sysdeps/hurd/pt-key-delete.c (pthread_key_delete): Remove all the values of the key in all the threads. * tests/Makefile (CHECK_SRC): Add test-17.c. * tests/test-17.c: New file.

<http://lists.gnu.org/archive/html/bug-hurd/2009-04/msg00028.html> Further comments by Neal: <neal> do you want a reply on the libpthread one inline? <neal> the short answer is: yes, that's a bug <neal> unfortunately, your fix is not enough <neal> the predicate controls two resources: the wakeup port and the thread itself <tschwinge> Oh, right, I see. <neal> also, there may be a race: <neal> set the predicate to free, then kill the thread <neal> that's not so good <neal> so a proper solution requires a bit more thought <tschwinge> I think I wondered about that as well. But isn't there the same problem with Viengoos? <neal> it is difficult as cleanly committing suicide is hard :-) <neal> could be <neal> on viengoos, I don't actually deallocate the thread in pt-thread-halt.c <neal> I just call suspend <neal> the thread is only deallocated in pt-thread-dealloc.c
