Package: samba
Version: 2:3.4.7~dfsg-1~bpo50+1
Severity: important
Tags: patch
The pam_winbind module leaks file descriptors. wb_common.c keeps its
file descriptor in the winbindd_fd global variable and closes that
through the winbind_close_sock function, but there's no provision for
making sure that winbind_close_sock is called when pam_winbind is closed
via dlclose.
A symptom of this is that Apache, if set up to use its auth_pam module,
is eventually unable to authenticate new users.
The attached patch instructs gcc to treat winbind_close_sock as a
destructor. This is the simplest fix but maybe not the best; from
looking at the docs, specifying a cleanup function to pam_set_data (and
doing something else for nss_winbind?) may be more correct.
