Added Files:
krb5-1.6.3-cc_gen_new-locks.patch
Log Message:
- krb5_fcc_generate_new(): unlock the fcc list lock before returning in the
non-mkstemp() case, don't unlock the lock twice before returning if we
happen to run out of memory (fixed in trunk by rewriting the function)
krb5-1.6.3-cc_gen_new-locks.patch:
--- NEW FILE krb5-1.6.3-cc_gen_new-locks.patch ---
We lock "krb5int_cc_file_mutex" before attempting to open the file in the
we-don't-have-mkstemp() case. And we shouldn't be trying to unlock it twice.
The function's rewritten in 1.6.4, but fix it here in the meantime.
