[Bug 733523] New: /var/lock permissions re: arduino, minicom
https://bugzilla.novell.com/show_bug.cgi?id=733523 https://bugzilla.novell.com/show_bug.cgi?id=733523#c0 Summary: /var/lock permissions re: arduino, minicom Classification: openSUSE Product: openSUSE 12.1 Version: Final Platform: x86-64 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: s2@forceway.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:8.0) Gecko/20100101 Firefox/8.0 It seems something has changed from openSUSE 11.4. Programs like minicom & arduino (IDE) worked fine before if you added your user to the uucp & dialout groups. Now arduino gives an error like: LOCKING /dev/ttyUSB0 lib_lock_dev_lock() lockstatus fail, are you in group 'lock'? .and you are unable to select a serial port in the menu. minicom displays a similar lock error. Adding user to the lock group has no effect. The quick workaround is: sudo chmod g+rwx,o+rwt /var/lock Reproducible: Always Steps to Reproduce: 1. have a serial port. 2. install & run minicom -D /dev/ttyUSB0 (for example) 3. lock error message Actual Results: "Cannot create lockfile..." Expected Results: should be able to create locks somehow -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Should mtab be changed to get what we want? .and I guess what we want is a group that the user could be added to to get the right permissions.

That may give the user more access than intended. 2. permissions for /var/lock are wrong with systemd. It should be 0775 root:lock. /var/lock/lockdev and /var/lock/subsys should not exist on openSUSE. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

MPIDE from ChipKIT.org project. Still have this problem - when run as normal user (the use IS added to "lock" group): LOCKING /dev/ttyUSB0 lib_lock_dev_lock() lockstatus fail, are you in group 'lock'? LOCKING /dev/ttyS31 lib_lock_dev_lock() lockstatus fail, are you in group 'lock'? LOCKING /dev/ttyS30 lib_lock_dev_lock() lockstatus fail, are you in group 'lock'? LOCKING /dev/ttyS29 lib_lock_dev_lock() lockstatus fail, are you in group 'lock'? LOCKING /dev/ttyS28 lib_lock_dev_lock() lockstatus fail, are you in group 'lock'? .. The program does not work - it does not allow me to work with the connected board. When run as root: LOCKING /dev/ttyUSB0 LOCKING /dev/ttyS31 LOCKING /dev/ttyS30 LOCKING /dev/ttyS29 LOCKING /dev/ttyS28 LOCKING /dev/ttyS27 LOCKING /dev/ttyS26 LOCKING /dev/ttyS25 .. The program works. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
