Package: xscreensaver
Version: 4.24-5
Severity: normal
Hi,
I experience a problem when using xscreensaver in recent times to lock my
X session: after authentication succeeds or fails (but a non-empty
password was entered) xscreensaver crashes with SIGABORT, from the
strace I can see the program tries to write a message from libnss-ldap
to stderr which is perhaps the real source of the problem: my user
database is stored in an openldap server on the local host,
which is accessed via nscd on
uri ldapi://%2fvar%2frun%2fslapd%2fldapi/
(by real source I mean not the fact that I use ldap per se, but rather
that perhaps code in libnss-ldap is broken), unfortunately at that
moment, 2 is already no longer stderr but some pipe (see dup earlier
in the trace).
There are two common errors in programs which as an ldap user I
constantly experience:
* programs rely on get*ent to not open a file descriptor (and
e.g. close stderr before calling getpwent)
* libnss-ldap likes to be really verbose but daemons often close
stderr, which leads to sometimes really broken files
So my two pleas for better programs:
* Use syslog if unsure wether stderr is really pointing to something
resembling an error output.
* Don't rely on getent not opening/using new file-descriptors (at
least libnss-ldap keeps a socket to the ldap server open).
I hope my (perhaps longer than required) description here and the
attached strace are sufficient, if not I can surely produce more
verbose output.
The strace was produced via
strace -t -e write=2 -o /tmp/xscreensaver.log xscreensaver
- lock screen
- move mouse, enter any string as password
- edit password from log
gzip -9 /tmp/xscreensaver.log
BTW: chmod u+s /usr/bin/xscreensaver makes no difference with respect
to the above
I'm filing this bug for xscreensaver because it's the only program
that's affected on my computer AFAIK.
Ciao, Thomas Jahns
