Since a few days I got the following Output while booting my system: ----------------- * Configuring system to use udev... * Populating /dev with device nodes... /sbin/rc: line 80: 1010 Segmentation fault /sbin/udevstart * Using /sbin/hotplug for udev management... ----------------- I tried to recompile udev and also tested it with CFLAGS="" but nothing fixed it. I am using sys-fs/udev-032 at the moment. Reproducible: Always Steps to Reproduce: 1. boot my gentoo 2. or start /sbin/udevstart manually 3.

Are you using the "hardened" toolchain? Odd. Can you run udevtest on the command line? Or udevinfo?
Oh, you are running a modified rule set, right? If you only use the rules that come with the udev package, does that work? Care to attach your modified rules and/or permissions?
Created attachment 40015 [details] 10-local.rules >Are you using the "hardened" toolchain? As you can see in my "emerge info" I am using the hardened-dev-sources and SSP in my CFLAGS. Additionally I compiled sys-libs/glibc with "erandom hardened nptl pic"-Flags. I am going to compile it without these USE-Flags to check if that is the source of the fault. udevinfo is not working for "-q path $DEVICE": -------------------------- ~ # udevinfo -q path -n /dev/sda device not found in database ~ # udevinfo -q path -n /dev/hda device not found in database -------------------------- But it works for something like "udevinfo -a -p /sys/block/sda" >If you only use the rules that come with the udev package, does that work? It does (see below), I attached my local rules. -------------------------- ~ # mv /etc/udev/rules.d/10-local.rules . ~ # udevinfo -q path -n /dev/hda /block/hda ~ # udevstart ~ # mv 10-local.rules /etc/udev/rules.d/10-local.rules ~ # udevstart Segmentation fault --------------------------
Update: Installing sys-libs/glibc without "erandom hardened nptl pic" did not change anything.
Should be fixed in latest (033) release.
Works great. Thank you.
