Status in sg3-utils package in Ubuntu: Fix Released Status in sg3-utils source package in Bionic: In Progress Status in sg3-utils source package in Disco: Fix Committed Status in sg3-utils source package in Eoan: Fix Released Status in sg3-utils source package in Focal: Fix Released Bug description: [Impact] * sg3-utils-udev package introduces 55-scsi-sg3_id.rules udev rule that take places BEFORE rules either finding correct ID_SERIAL for the USB block device, or calculating it from "usb_id" parameter: - this rule changes USB ID_SERIAL parameter for the ones given by the Vital Product Data from the block device. - USB memory sticks might not provide VPD pages (0x80, 0x83) and, because of that, the USB ID_SERIAL will be broken. - because the failure in sg_inq command from the 55-XXX udev rules file, to obtain the VPDs, the udev ACTION(add) takes long time and consumers might not have considered a "settle" need. * Anything depending on ID_SERIAL udev attribute from USB block devices might not find appropriate device. * Any type of udev consumer not calculating the need for a big time-consuming "udevadm settle" right after a pen drive is inserted might not be able to see all USB block devices attributes from udev. [Test Case] * Install package "sg3-utils-udev", monitor journalctl -f while introducing a memory stick in your machine and watch sg_inq command failing: systemd-udevd[1021]: Process '/usr/bin/sg_inq --export --inhex=/sys/block/sdb/device/vpd_pg83 --raw' failed with exit code 15. * Compare udevadm attributes with and without "sg3-utils-udev" package is installed: Without sg3-utils 55-scsi-sg3_id.rules: $ udevadm info --query=all --name=/dev/sdb | grep -i serial E: ID_SERIAL=Corsair_Voyager_Mini_3.0_070851D0E490C776-0:0 E: ID_SERIAL_SHORT=070851D0E490C776 With 55-scsi-sg3_id.rules: $ udevadm info --query=all --name=/dev/sdb | grep -i serial E: ID_SERIAL=3 E: ID_SERIAL_SHORT=2000acde48234567 [Regression Potential] * Minor: either I brake functionality for sg3-utils packages on USB block devices. Since sg3-utils is used mostly for SCSI debugging, management and investigations, its a very minor risk. * The change is a 1 line change in a udev rule file, very easy to test following the test case.
