ini_parse failure causes php error on main page #58

Closed verrier closed 4 years ago

verrier commented 4 years ago

Root cause: Seems like a failure in ini_parse with certain values is causing the PHP error displayed below to appear on the main screen and no details for the drive to display.

Details image

Warning: syntax error, unexpected '=' in Unknown on line 30 in /usr/local/emhttp/plugins/unassigned.devices/include/lib.php on line 1455

Root Cause

Line 1455 of the affected file is: $state[$device] = parse_ini_string(timed_exec(5,"/sbin/udevadm info --query=property --path $(/sbin/udevadm info -q path -n $device 2>/dev/null) 2>/dev/null"));

If we break down each component, the affected device in my example is /dev/sdd... /sbin/udevadm info -q path -n /dev/sdd returns:

/devices/pci0000:00/0000:00:11.4/ata3/host3/target3:0:0/3:0:0:0/block/sdd

Taking the syspath, and putting it in the first half of the commands, results in: /sbin/udevadm info --query=property --path /devices/pci0000:00/0000:00:11.4/ata3/host3/target3:0:0/3:0:0:0/block/sdd

Line 30 of the parsed ini file is: ID_FS_UUID=MARVELL___#___#___f$__f$ ... which I assume at this point the $ in the result is throwing parse_ini for a loop since it's not escaped.

I've just issued an update to UD that should solve this issue. Update and let me know if it solves the problem,

Glad it's solved for you. Php string handling can be a real challenge at times.
