linux/poky.git/meta/recipes-core/udev, branch master

The poky repository master branch is no longer being updated.

2025-11-07T13:31:53+00:00

You can either: a) switch to individual clones of bitbake, openembedded-core, meta-yocto and yocto-docs b) use the new bitbake-setup You can find information about either approach in our documentation: https://docs.yoctoproject.org/ Note that "poky" the distro setting is still available in meta-yocto as before and we continue to use and maintain that. Long live Poky! Some further information on the background of this change can be found in: https://lists.openembedded.org/g/openembedded-architecture/message/2179 Signed-off-by: Richard Purdie

udev-extraconf: Avoid slashes in mountpoint names

2025-10-06T22:15:59+00:00

Devices with labels such as "Hello/World/Foo/Bar" cause mount.sh to create the directory structure @MOUNT_BASE@/Hello/World/Foo/Bar. The partition is mounted to the nested "Bar" directory. On device removal, the directory structure is not cleaned up. This commit replaces all forward slashes in partition labels by underscores to avoid this edge case.

udev-extraconf: Speed up mount.sh

2025-10-06T22:15:59+00:00

On devices with many partitions, running blkid without parameters can be rather slow because all block devices are inspected: $ time /sbin/blkid real 0m0.474s user 0m0.026s sys 0m0.172s versus $ time /sbin/blkid /dev/mmcblk0p10 real 0m0.027s user 0m0.002s sys 0m0.018s Plugging in a device with 5 partitions means that mount.sh is going to be executed 5 times, and so will be blkid. In the real-world case outlined above, this adds up to an overhead of about 2.3 seconds for blkid alone. This commit changes mount.sh so that the block device of interest is passed directly to blkid such that blkid inspects only that device, leading to significant speedup.

meta: set S from UNPACKDIR in recipes that use only local files

2025-06-20T11:07:26+00:00

There is no need to have two assignments; also setting S from UNPACKDIR (and not vice versa) is more logical as unpack task comes first, and tasks that come after unpack use S to access unpack results. Also adjust reference test data in selftest/recipeutils to reflect changes in test recipes.

classes/recipes: remove unnecessary qemu inherit and use qemuwrapper-cross

2025-04-23T08:47:42+00:00

These classes/recipes inherit qemu.bbclass but do not use anything from it. What they use is qemuwrapper-cross, which is needed at do_rootfs time and needs to be pulled-in by PACKAGE_WRITE_DEPS. Also, in meta/conf/layer.conf, exclude qemuwrapper-cross deps for all arch recipes that depend on it. This it ensure allarch recipes have the same signature across different machines.

eudev: Drop --output=... from kmod call in init script

2025-03-17T17:09:22+00:00

This awkward invocation is no longer required as kmod just uses the stdout file descriptor, rather than explicitly opening /dev/stdout. (From OE-Core rev: c54e9e205c5cc45c37c34a472a7e78266ee17983) Signed-off-by: Alex Kiernan Signed-off-by: Richard Purdie

eudev: backport patch to fix udevd hanging while trying to access /dev/urandom

2025-01-21T12:07:56+00:00

Linux kernel commit 48bff1053c17 ("random: opportunistically initialize on /dev/urandom reads") introduced a change where /dev/urandom blocks if the random pool is insufficiently initialized during hardware boot. This behavior causes /dev/urandom reads to hang for approximately 5 seconds, delaying the boot process with eudev init script (when it calls udevd). This issue has already been solved upstream, therefore backport the upstream patch to fix this.

udev-extraconf: Allow FAT mount group to be specified

2025-01-14T11:57:52+00:00

Adds a variable that allows the group given permissions to access FAT mounted file systems to be specified, instead of being hardcoded to 'disk'. As a note, the usage of 'disk' as the mount group is not a very secure default, since the disk user usually has read/write access to all block devices in /dev/, meaning that adding a user to this group for the purpose of accessing FAT file systems effectively gives the write access to all block devices.

udev-extraconf: fix network.sh script did not configure hotplugged interfaces

2024-10-22T11:28:18+00:00

Udev script network.sh is called when a new ethernet interface is plugged (eg. USB). Due to some (old) missing files, this script does nothing, instead of configuring the interfaces with ifup. I just commented the corresponding lines to allow the script to reach the part where it calls ifup. (From OE-Core rev: 160f7139172ffdf510a0d7d4e85f7fbaac7fd000) Signed-off-by: Regis Dargent Fixes [YOCTO 15616] network.sh relies on (long) missing files (eg. /etc/network/options, /etc/init.d/network) to decide if it should configure the new network interface (ifup) or put its name in /etc/udev_network_queue for future initialization by /etc/init.d/network service. The actual result was that the new hotplugged interface was never automatically configured. Removing the obsolete tests allows the script to do its intended job.
