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

2024-11-26T13:37:09+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: 55069a5f68ade552e3c45333d441dc2d18753476) 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.

udev-extraconf: Add collect flag to mount

2024-09-10T12:05:00+00:00

Adds extra "--collect" flag to the mount command within automount_systemd. This is intended to fix an observed deadlock after rapidly inserting and removing external media. This is because if the mount command fails, the transient mount will enter a failed state. The next time the media is inserted, automount_systemd bails because the first consition finds that the file path for the failed transient mount still exists. This leaves the external media unmounted and cannot be mounted until the mount is fixed via systemctl or the device is rebooted. Adding "--collect" ensures that the transient mount is cleaned up after entering a failed state, which ensures that the media can still be mounted when it's re-inserted.

udev-extraconf: fix unmount directories containing octal-escaped chars

2024-01-26T16:06:29+00:00

USB devices are auto-mounted in a directory named like theirs labels. Special characters like whitespace are octal-escaped in /proc/mounts output. Using directly this output file as an argument for umount failed and the mount directory can't be removed as still busy. Using printf allows these special characters to be unescaped.

udev-extraconf: mount.sh: check if filesystem is supported before mounting

2023-11-10T17:44:27+00:00

Check if the filesystem is supported by the kernel before trying to mount it. Systemd-mount will mount the directories asynchronously resulting in stale directories if the devices filesystem is not supported.

udev-extraconf:mount.sh: fix a umount issue

2022-07-23T12:55:26+00:00

Only touching /tmp/.automount-$name is not good enough, it must contain the mount name, otherwise umount could not get the path from it. (From OE-Core rev: ccea69032329f3ba43c727d9eb71b1d063b89824) Signed-off-by: Ming Liu Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie

udev-extraconf:mount.sh: fix path mismatching issues

2022-07-15T11:33:21+00:00

Since commit f077befd5f36ad88623aaf6a38b1a837ecb18650: [ udev-extraconf: let automount base directory configurable ] the mount base directory was configurable, we need drop 'run-media' usage as well, change to figure it out from MOUNT_BASE. Also 'get_label_name' function needs to be called ealier in automount_systemd before checking '/tmp/.automount-$name', otherwise they would never match.

udev-extraconf: fix some systemd automount issues

2022-06-27T22:11:12+00:00

The '.include' syntax has been dropped from latest systemd releases, we need drop the systemd-udevd.service here, introduce a postinst function to add "MountFlags=shared" to systemd-udevd.service. Also lsblk binary is being called in mount.sh automount_systemd function, add it to RDEPENDS.

udev-extraconf/mount.sh: ignore lvm in automount

2022-06-21T17:44:27+00:00

Failure message is shown in boot logs when trying to mount lvm as automounter does not handle cases where lvm is mounted. This simply skips lvm while automounting to avoid failure message in boot logs.

udev-extraconf: force systemd-udevd to use shared MountFlags

2022-06-21T17:44:27+00:00

Automounting does not work cleanly in case systemd as well as udev rules are being used simultaneously and in most cases race conditions and unknown behavior can come up. In case we're running on top of systemd we need to make sure that systemd-udevd knows that udev is in play as well and mounting should be done using shared flags. Also as we're using mount from sources other than systemd-mount in current scripts this is the most manageable fix to automounting problems.

udev-extraconf/mount.sh: only mount devices on hotplug

2022-06-21T17:44:27+00:00

fdisk from util-linux (2.31.1) and above allows the user to manipulate an already mounted device. In order to achieve this functionality it issues a BLKRRPART (block device re-read part) ioctl and in response the kernel generates remove/change/add events if the device is not mounted (manually unmounted etc) which are caught and processed by udev. This causes our auto-mounter to remount everything because it does not keep track and things go out of control. Differentiating between types of remove events such as the one described above (generated by BLKRRPART) and one where the device is physically plugged out is only possible using the DEVPATH variable which is cleaned up only when the device is actually plugged-out. This fixes the above anomaly by only mounting a device in add event which is cleaned up properly (tmp cache deleted) in the remove event or is not present in the tmp cache while making use of the DEVPATH variable during the remove action.
