* eudev: Replaces udev with eudev for compatibility when using sysvinit on ↵Alejandro Hernandez2016-03-021-142/+0
| | | | | | | | | | | | | | | | | | | newer kernels udev has started to fail on new kernels (4.4), due to being deprecated in favor of systemd's udev implementation. To maintain a sysvinit alternative we also need to provide an alternative to udev. Eudev is a fork of systemds udev, this new eudev recipe provides upstream udev 220 funcitonality. - Removes patches that dont apply anymore - ToDo: eudev-ptest?

* udev-cache: invalidate on rules.d changesRichard Tollerton2014-12-191-0/+6
| | | | | | | | | | | | | | | Presently, the cache is not regenerated if udev rules are modified, which may cause the cache to preserve an old configuration. To fix, include the size, mtime, and filename of all udev rules in the system configuration. This change requires `stat`. If busybox supplies stat, CONFIG_FEATURE_STAT_FORMAT must be enabled.

* udev-cache: refactor sysconf generationRichard Tollerton2014-12-191-4/+11
| | | | | | | | | | | | | | The current system configuration needs to be generated both inside udev (to compare against the cached system configuration) and udev-cache (to regenerate the cached system configuration). Use a single function definition for this task, duplicated across both initscripts. This also allows administrators to modify it for machine-specific requirements.

* udev-cache: don't generate sysconf twiceRichard Tollerton2014-12-191-1/+4
| | | | | | | | | | | | The udev initscript signals udev-cache to run by generating a new sysconf; but udev-cache now overwrites that with its own copy. To eliminate the needless sysconf generating in udev, we instead trigger udev-cache to run by touching a new file $DEVCACHE_REGEN.

* udev-cache: replace readfiles() with cmpRichard Tollerton2014-12-191-22/+7
| | | | | | | | | | | | | | | | | | | | | Currently, udev-cache system configurations are compared as shell string variables, read into memory with the readfiles() function. This is more complex, and significantly (27-41%) slower, than comparing them using `cmp`. (Performance was verified on both Cortex-A9 and Intel Nehalem systems.) So just use cmp. This requires a few other small changes: exclude /proc/atags from CMP_FILE_LIST if it doesn't exist to avoid errors in `cat` and `cmp`. `cmp -q` doesn't exist in busybox, so instead, redirect output to /dev/null.

| | | | | | | | | | | | | | | | | | | | | | Make sure that /proc/sys/kernel/hotplug exists before trying to disable the uevent-helper mechanism. Since kernel commit 86d56134f1b6 ("kobject: Make support for uevent_helper optional.") the kernel can be built without uevent-helper support. In this case /proc/sys/kernel/hotplug does not exist and the current sysvinit script fails with /etc/rcS.d/S04udev: line 132: can't create /proc/sys/kernel/hotplug: nonexistent directory when trying to disable the uevent-helper mechanism during boot. Note that a single NULL-character has always been sufficient to disable.

* udev-cache: strip timestamps on extractRichard Tollerton2014-08-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | Under normal udev operation, device nodes are obviously timestamped based on the system time at current boot. However, when using udev-cache, they are timestamped from a previous boot. The existence of machines lacking RTCs makes this more than a cosmetic issue: if the current time is set further on in the boot, so that the system time is still 1970 by the time the cache is extracted, tar will print a timestamp warning for every extracted file (potentially hundreds of them). To fix, use -m on extract. If using busybox `tar`, this commit requires CONFIG_FEATURE_TAR_NOPRESERVE_TIME=y.

* udev: update init script for conditional probing of platform busDenys Dmytriyenko2014-06-251-1/+6
| | | | | | | | | | | | | | | | | Make probing of "platform" bus conditional based on PROBE_PLATFORM_BUS variable from /etc/default/udev-cache on subsequent boots when udev cache is used. PROBE_PLATFORM_BUS has to be set to "yes" in order to force probing on every boot, otherwise it uses the old default behaviour of probing it just the first time. This is helpful on modern SoCs where most of the low level peripheral drivers are registered on the platform bus and need to be probed to load the necessary modules and enable the connected buses and subsystems.

* sysvinit: adjust boot sequence and remove hack from udevChen Qi2013-11-081-1/+3
| | | | | | | | | | | | | | | | | | | | | Adjust the boot sequence in sysvinit based systems. The mountall.sh (mounting the local file system) needs to be started before udev and bootlogd. This patch makes mountall.sh start before udev and removes the hack of mounting tmpfs in the udev init script. This patch also adds some comments to the udev init script to make it clear why we create the '/var/volatile/tmp' directory.

* udev: remove implicit dependency on initscriptsChen Qi2013-08-161-4/+12
| | | | | | | | | | | | | | | | | | At some point, the udev was modified to source the functions from initscripts or lsbinitscripts. This dependency is actually not needed. If we use udev in a system where initscripts from oe-core is not available, there will be errors. This patch fixes this problem by removing the implicit dependency.

* udev-cache: take a read-only rootfs into considerationChen Qi2013-07-021-22/+32
| | | | | | | | | | | | | | | | | | | | | | In case of a read-only rootfs, we skip the process of generating udev cache, as the data cannot be persisted between reboots. However, it's possbile that the $DEVCACHE (default to /etc/dev.tar) exists in a read-only rootfs, no matter how it's generated or installed. In such situation, we try to use $DEVCACHE if possible. Besides the basic changes in the logic of udev cache handling, this patch also adds code to output more information if the udev cache is not used and VERBOSE enabled. This patch also changes the readfile function to readfiles function so that it could handle more than one file at once.

* udev: only use devtmpfs for udevAlex Olson2013-06-281-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Fix for bug: https://bugzilla.yoctoproject.org/show_bug.cgi?id=4632 Since udev 172, the 'mknod' logic was removed from udev. Yocto Dylan is now using udev 182. This means /dev is now required to be a devtmpfs filesystem (maintained by the kernel). If the root filesystem is a ramdisk, the kernel's auto-mount of /dev doesn't activate since there is no rootfs to actually mount... The bug causes an unusable system as /dev doesn't contain even basic nodes required to even get a login prompt. The Yocto udev/init script mounts tmpfs if it does not detect tmpfs or devtmpfs mounted at /dev. This appears to be outdated logic that is no longer correct. I believe the Yocto udev init script should be checking and mounting only 'devtmpfs' on dev.

* udev-cache: fix to use udev-cache correctlyChen Qi2013-06-251-1/+5
| | | | | | | | | | | | | | | | | | | Previouly, the udev-cache has no real effect even if it's installed into the system. The key problem here is that at first boot, the /etc/dev.tar is not present, thus resulting /dev/shm/udev.cache not created on first boot even if udev-cache is enabled. This patch fixes this problem. The /dev/shm/udev.cache will be created if necessary, that is, on first boot or when some part of the system is changed. In the latter case, the udev cache may not be valid.

| | | | | | | | | | | | | | | | Previously in udev init, /var/volatile/run had to be created after mounting all tmpfs filesystems so that udevd can write to /var/run (a symbolic link to /var/volatile/run). This is because udev is started before populate-volatile.sh. Now that /var/run is a symbolic link to /run (a tmpfs filesystem), /var/volatile/run doesn't need to be created anymore.

* udev: create /var/volatile/tmp to avoid dead linkChen Qi2013-04-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | If it's not first boot, /tmp has already been symlinked to /var/volatile/tmp. But the udev service starts before populate-volatile.sh starts. This leads to a dead link at /tmp. As a result, trying to create any file under /tmp will fail. If a USB is plugged in before the populate-volatile.sh script starts, the /tmp/.automount-$name file will not be created correctly. As a result, when the USB is unplugged, the /media/$name directory is not removed. So we create /var/volatile/tmp directory in the udev script to avoid this dead link problem.
