Bjorn Leffler has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1246765?usp=email ) Change subject: Initialise export_opt_lock statically ...................................................................... Initialise export_opt_lock statically nfsd is built from MainNFSD/nfs_main.c, which never calls PTHREAD_RWLOCK_init() on export_opt_lock -- only the library entry point nfs_lib.c does -- yet export_defaults_commit() write-locks it while reading exports. A zeroed pthread_rwlock_t happens to be a valid unlocked lock on glibc, so this goes unnoticed there. It is not guaranteed by POSIX, and pthread implementations that validate the lock reject it: export_defaults_commit :RW LOCK :CRIT :Error 22, write locking PTHREAD_RWLOCK_INITIALIZER is all-zero on glibc, so the generated code is unchanged there.
