Description
Be sure the
__lock_release_recursive(dirp->dd_lock);
is being called before theclosedir(dirp);
otherwise it will crash as thedirp->dd_lock
is going to be deleted inclosedir
and on top of that thedirp
is freed also inclosedir
.This issue has been there in
newlib
for years, however, it wasn't noticed because first of all LOCK API looks to be barely used, and secondly because it also requires the flagHAVE_DD_LOCK
to be enabled.Cheers.
