Bug ID: 198015 Summary: devd(8) overwrites "bus" on ugen event Product: Base System Version: 10.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: usb Assignee: freebsd-usb@FreeBSD.org Reporter: jo...@stromnet.se Problem: When trying to match a uftdi device arrival, "bus" variable is overwritten. This means I cannot know which /dev/ugenN.N node to work with (which in my case is chown to a specific user). Example: (FreeBSD 10.1, devd in console mode): Sample devd script: attach 10 { device-name "uftdi[0-9]+"; action "chgrp dialer /dev/ugen$bus.$devaddr; chmod 660 /dev/ugen$bus.$devaddr" }; Processing event '+uftdi0 at bus=0 hubaddr=1 port=3 devaddr=2 interface=0 vendor=0x1781 product=0x0c30 devclass=0x00 devsubclass=0x00 sernum="XXXXXX" release=0x0600 mode=host intclass=0xff intsubclass=0xff intprotocol=0xff ttyname=U0 ttyports=1 on uhub1' Pushing table setting device-name=uftdi0 setting bus=0 setting hubaddr=1 setting port=3 setting devaddr=2 setting interface=0 setting vendor=0x1781 setting product=0x0c30 setting devclass=0x00 setting devsubclass=0x00 setting sernum=A6008W8a setting release=0x0600 setting mode=host setting intclass=0xff setting intsubclass=0xff setting intprotocol=0xff setting ttyname=U0 setting ttyports=1 setting bus=uhub1 Processing attach event Testing device-name=uftdi0 against ^ed50$, invert=0 Testing device-name=uftdi0 against ^ubt[0-9]+$, invert=0 Testing device-name=uftdi0 against ^ukbd0$, invert=0 Testing vendor=0x1781 against ^0x0854$, invert=0 Testing vendor=0x1781 against ^0x1645$, invert=0 Testing device-name=uftdi0 against ^uftdi[0-9]+$, invert=0 Testing vendor=0x1781 against ^0x0403$, invert=0 Testing device-name=uftdi0 against ^uftdi[0-9]+$, invert=0 Testing vendor=0x1781 against ^0x1781$, invert=0 Testing product=0x0c30 against ^0x0c30$, invert=0 Executing 'chgrp dialer /dev/ugenuhub1.2; chmod 660 /dev/ugenuhub1.2' chgrp: /dev/ugenuhub1.2: No such file or directory chmod: /dev/ugenuhub1.2: No such file or directory Popping table My suspect: https://github.com/freebsd/freebsd/blob/master/sbin/devd/devd.cc#L821 Is there any other way to reliably get the corresponding ugen device? -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
