* eudev: Replaces udev with eudev for compatibility when using sysvinit on ↵Alejandro Hernandez2016-03-0216-921/+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: Add 2 patches to support 4.4 kernelSaul Wold2016-01-202-0/+81
| | | | | | | | | | | | | | These 2 patches are needed to build udev with the 4.4 kernel, the first mtd-probe adds back a stdint.h header that was removed in the kernel's mtd-user.h header file. The second adds a check for a new header and sets a Makefile variable to determine which header to use for the new kernel vs older kernels.

* udev-cache: refactor sysconf generationRichard Tollerton2014-12-192-5/+18
| | | | | | | | | | | | | | 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: replace readfiles() with cmpRichard Tollerton2014-12-192-36/+10
| | | | | | | | | | | | | | | | | | | | | 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.

* udev-cache: stop race between sysconf and cache generationRichard Tollerton2014-12-191-0/+18
| | | | | | | | | | | | | | | | | | | The validity of the udev cache is determined by the sysconf file (/etc/udev/cache.data). Currently, there is a substantial delay between sysconf generation in /etc/init.d/udev and cache generation in /etc/init.d/udev-cache. If a hotplug event arrives in the middle of this, then the sysconf will be out of date with respect to the cache. The solution is two-pronged. First, we minimize the race window by regenerating the sysconf immediately before the cache, in /etc/init.d/udev-cache. This allows us to kill the race entirely by stopping the udev event queue while the sysconf and cache are being generated.

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.

| | | | | | | | | | | | The udev-cache facility uses files that represent system states, to ensure that the cache tarball is valid to apply. These paths were hardcoded in several places; collect them into SYSCONF_CACHED and SYSCONF_TMP.

* udev-cache: omit sockets and filesystems mounted under /devRichard Tollerton2014-08-231-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Archiving sockets causes tar to report an error and return a nonzero exit status. Archiving a mounted filesystem is harmless, but may greatly bloat the size of the cache tarball, and wastes time on boot. To fix these issues, use `find` to only include the files we want, which are the file types that udev will create (block/char devices and symlinks) that are on the same filesystem as /dev. While we're at it, remove a subshell by archiving /dev as an absolute path. However, `tar` will complain about stripping the leading slash on stderr. To inhibit this, `cut` out the leading slash. An alternative solution is to use `tar --exclude`, but that is modestly more brittle, since we'd need to explicitly list every socket and filesystem to exclude. Note that `tar --one-file-system` is GNU-specific, and tar implementations generally have nothing equivalent to `find -type`. If using busybox `find`, this change requires CONFIG_FEATURE_FIND_TYPE=y and CONFIG_FEATURE_FIND_XDEV=y. If using busybox `tar`, this change requires CONFIG_FEATURE_TAR_FROM=y.

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * While working with a new capacitive touchscreen it was found that the existing udev rule that creates the /dev/input/touchscreen0 symlink was too restrictive and did not match the MODALAIS entry for this touchscreen. which is: MODALIAS=input:b0018v0000p0000e0000-e0,1,3,k14A,ra0,1,2F,35,36,39,mlsfw * By looking at the input_print_modalias function in the Linux kernel drivers/input/input.c file and referencing the meaning of the evbits and attributes of the input_dev structure it seems that for identification of a touchscreen the match with ,18 which was matching part of the absbit structure is overkill. * It seems that the absbit entry is used for devices like touchscreens and if that the the "a" is followed by 0 and 1 this is sufficient. * So the logic has now been changed to check for the "e" 0 and 3 values which correspond to EV_SYN and EV_ABS, then check for the "a" attribute with 0 and 1. * More information and history for this can be found at: http://patchwork.openembedded.org/patch/25093/ http://thread.gmane.org/gmane.comp.handhelds.openembedded.core * This patch mirrors a patch done by: Andrea Adami <andrea.adami@gmail.com> (From OE-Core rev: d95a9b516861594bc89c7ee8079bab2904703ad2) Signed-off-by: Chase Maupin <Chase.Maupin@ti.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* udev: avoid autosuspend of USB input devicesNitin A Kamble2013-09-171-0/+25
| | | | | | | | | | | | | | | | | | | | | | Some of the external USB devices has internal USB hub, which make them look like "fixed" rather than "removable". And USB autosuspend does not work with some of these devices resulting in inoperable pointing device. Now the code detect these false "fixed" devices by looking at their parents. If any of their parent is "removable", then USB autosuspend is not enabled for that device, which keeps the pointing device functional.

* 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 Qi2013-07-022-22/+38
| | | | | | | | | | | | | | | | | | | | | | 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 Qi2013-06-252-4/+6
| | | | | | | | | | | | | | | | | | | 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.

* udev: move /run volatile entry to udev instead of initscriptsRoss Burton2013-03-261-0/+1
| | | | | | | | | | | | | | | | initscripts is generally installed on systemd-using images, but because it specifies that /run is a symlink to /var/run managed by volatiles it totally breaks systemd by copying/deleting /run from underneath systemd. Deleting sockets mid-boot doesn't leave systemd in a happy place. As this volatile reference of /run was introduced by udev 182, move it's reference to the udev recipe. This way it will never be present on systemd images, as systemd manages /run as a tmpfs itself.
