Package: sudo Version: 1.7.4p4-2.squeeze.2 When I invoke programs through sudo (via cgi's) the executed programs finish sucessfully, but sudo hangs forever waiting for something. The executed program is left in a "zombie" process state (marked as <defunc> in the output of ps) and the sudo process never exits - it just hang. Here is how the the process list looks like, for example:
# ps fauxx .... root 2560 0.0 0.0 23940 1372 ? S Apr21 0:00 /usr/bin/sudo -E /opt/xyz/etc/http/survey/cgi-bin/control.py root 2562 0.0 0.0 0 0 ? Z Apr21 0:00 \_ [control.py] <defunct> root 3921 0.0 0.0 23940 1372 ? S Apr21 0:00 /usr/bin/sudo -E /opt/xyz/etc/http/survey/cgi-bin/control.py root 3923 0.0 0.0 0 0 ? Z Apr21 0:00 \_ [control.py] <defunct> root 4174 0.0 0.0 23940 1368 ? S Apr21 0:00 /usr/bin/sudo -E /opt/xyz/etc/http/survey/cgi-bin/control.py root 4176 0.0 0.0 0 0 ? Z Apr21 0:00 \_ [control.py] <defunct> root 1166 0.0 0.0 23940 1372 ? S 13:08 0:00 /usr/bin/sudo -E /opt/xyz/etc/http/survey/cgi-bin/control.py root 1167 0.0 0.0 0 0 ? Z 13:08 0:00 \_ [control.py] <defunct> If i trace the system calls of the sudo command, i can see that sudo waits endlessly in a select() system call which waits for file descriptors, which are already closed and Sudo will therefore wait forever. This Bug only Occurs on Debian Squeeze+ (Lenny works fine) This Bug is fixed in sudo 1.7.5 and and >1.8.0 (http://www.gratisoft.us/bugzilla/show_bug.cgi?id=447) I am using Debian GNU/Linux 6.0, kernel 2.6.32-5-amd64 and libc6 2.11.2-10. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
