Package: lockdev
Severity: important
The special-casing of ttys looks particularly borked:
if ( strcmp( p, "tty") == 0 )
p = ttyname( 0); /* this terminal, if it exists */
What has the ttyname of the controlling terminal got to do with
locking any other device /dev/tty*? The call could also potentially
return NULL if called by a daemon with no controlling terminal, which
will cause problems later on.
Example: program running on /dev/tty2, calls dev_lock("/dev/ttyS4")
==> creates LCK..tty2
Example: daemon without controlling tty calls the same
==> ???
My ppc system doesn't have serial ports, so I can't actually test this
properly. The code doesn't look right, however.
Regards,
Roger
