[Pkg-samba-maint] Bug#410663: winbind leaking file descriptors

[Yves Junqueira]

Package: winbind
Version: 3.0.23d-4
Severity: normal
Tags: patch


When using Winbind for authentication in an AD domain by Squid, my var partition quickly with 146Gb of logs
in syslog with the following message:

winbindd: Exceeding 200 client connections, no idle connection found

That is a known bug in Winbind. See https://bugzilla.samba.org/show_bug.cgi?id=3204

The fix provided is:

--- samba/source/nsswitch/winbindd.c    (revision 176)

-       if ((state = TALLOC_ZERO_P(NULL, struct winbindd_cli_state)) == NULL)
+       if ((state = TALLOC_ZERO_P(NULL, struct winbindd_cli_state)) == NULL) {
+               close(sock);
                return;
+       }

        state->sock = sock;

I'm still confirming if that fixes the problem. If so, could this go to Etch, please?

Thank you.
