From 8648bd1f6db679aa078a7d25327f8ae792514774 Mon Sep 17 00:00:00 2001 From: Ricardo Cañuelo Date: Wed, 10 Jun 2020 10:49:54 +0200 Subject: tools: add custom udev rules to generated images Add a default udev rule file to the image creation process in create-gce-image.sh and create-image.sh. This change creates a default rule to make udev create a custom-named symlink for the specific vim2m device. --- pkg/build/linux_generated.go | 2 ++ tools/create-gce-image.sh | 4 ++++ tools/create-image.sh | 4 ++++ 3 files changed, 10 insertions(+) diff --git a/pkg/build/linux_generated.go b/pkg/build/linux_generated.go index cd3b32077..7432cf3ef 100644 --- a/pkg/build/linux_generated.go +++ b/pkg/build/linux_generated.go @@ -96,6 +96,8 @@ for i in {0..31}; do sudo tee -a disk.mnt/etc/udev/50-binder.rules done +echo 'ATTR{name}=="vim2m", SYMLINK+="vim2m"' | sudo tee -a disk.mnt/etc/udev/rules.d/50-udev-default.rules + echo "kernel.printk = 7 4 1 3" | sudo tee -a disk.mnt/etc/sysctl.conf echo "debug.exception-trace = 0" | sudo tee -a disk.mnt/etc/sysctl.conf SYZ_SYSCTL_FILE="${SYZ_SYSCTL_FILE:-}" diff --git a/tools/create-gce-image.sh b/tools/create-gce-image.sh index b9e76d24e..39ec49cbe 100755 --- a/tools/create-gce-image.sh +++ b/tools/create-gce-image.sh @@ -145,6 +145,10 @@ for i in {0..31}; do sudo tee -a disk.mnt/etc/udev/50-binder.rules done +# Add udev rules for custom drivers. +# Create a /dev/vim2m symlink for the device managed by the vim2m driver +echo 'ATTR{name}=="vim2m", SYMLINK+="vim2m"' | sudo tee -a disk.mnt/etc/udev/rules.d/50-udev-default.rules + # sysctls echo "kernel.printk = 7 4 1 3" | sudo tee -a disk.mnt/etc/sysctl.conf echo "debug.exception-trace = 0" | sudo tee -a disk.mnt/etc/sysctl.conf diff --git a/tools/create-image.sh b/tools/create-image.sh index 32cdfcdb5..0967b4c37 100755 --- a/tools/create-image.sh +++ b/tools/create-image.sh @@ -119,6 +119,10 @@ if [ $PERF = "true" ]; then rm -r $DIR/tmp/linux fi +# Add udev rules for custom drivers. +# Create a /dev/vim2m symlink for the device managed by the vim2m driver +echo 'ATTR{name}=="vim2m", SYMLINK+="vim2m"' | sudo tee -a $DIR/etc/udev/rules.d/50-udev-default.rules + # Build a disk image dd if=/dev/zero of=$RELEASE.img bs=1M seek=$SEEK count=1 sudo mkfs.ext4 -F $RELEASE.img -- cgit mrf-deployment
