Description

Console switch uses udev rule to mapping usb tty devices to fixed tty device. More detial can be found in this HLD: https://github.com/Azure/SONiC/blob/master/doc/udev-terminalserver/udev%20rules%20for%20Terminal%20Server.md

According to our design in this PR: #5571
A udevprefix.conf file will be put on platform's plugin folder after the usb console switch plugged on, but it not.

I run the script by myself and it works:

admin@sonic:~$ ls /usr/share/sonic/device/x86_64-cel_e1031-r0/plugins/
eeprom.py  eeprom.pyc  pcie.yaml  psuutil.py  sfputil.py

admin@sonic:~$ sudo bash /usr/local/bin/udev_prefix.sh C0-

admin@sonic:~$ ls /usr/share/sonic/device/x86_64-cel_e1031-r0/plugins/
eeprom.py  eeprom.pyc  pcie.yaml  psuutil.py  sfputil.py  udevprefix.conf

Seems like the udev rule not trigger the script correctly?

All above testing are based on master branch's build 492.

Steps to reproduce the issue:

  1. Install image 492
  2. Check /usr/share/sonic/device/x86_64-cel_e1031-r0/plugins/

Describe the results you received:
No udevprefix.conf found

Describe the results you expected:
There is a udevprefix.conf file and the content in it is C0-

This file depends on your udev rules design. Here is an example about how to generate this file. e.g: ACTION=="add" ,KERNEL=="ttyUSB*",SUBSYSTEM=="tty",KERNELS=="1-1.1",ATTRS{idProducc t}=="2517",ATTRS{idVendor}=="0424",RUN+="/bin/bash -c '/usr/local/bin/udev_prefii x.sh C0-'",GOTO="C0 Add" When the device is plugged in, "udev_prefix.sh" would be called .And in udev_prefix.sh it would generate the udevprefix.conf. Here is an example of udev_prefix.sh #!/bin/bashPREV_REBOOT_CAUSE="/host/reboot-cause/"DEVICE="/usr/share/sonic/device"PLATFORM=$(/usr/local/bin/sonic-cfggen -H -v DEVICE_METADATA.localhost.platform)FILES=$DEVICE/$PLATFORM/pluginsFILENAME="udevprefix.conf"if [ "$1" = "clear" ]then if [ -e $FILES/$FILENAME ]; then rm $FILES/$FILENAME fielse if [ -e $FILES/$FILENAME ]; then : > $FILES/$FILENAME echo -n "$1" > $FILES/$FILENAME else touch $FILES/$FILENMAE echo -n "$1" > $FILES/$FILENAME fifi

Hi Sandy, we are using the rule you provided(https://github.com/sandycelestica/sonic-buildimage/blob/master/platform/broadcom/sonic-platform-modules-cel/haliburton/script/50-ttyUSB-C0.rules), seems like the script were not executed when plugged in. But the following SYMLINK added successfully. This issue can be repro on my testbed, is possible to test it on your side?

I tested this before I upload the code. If needed I could set up the environment to reproduce this issue.
Could you please share with me the test log? Including "ls /dev/*", "lsusb" ,"lsusb -t"

Yeah. Seems like both LN11 and LN12(https://github.com/sandycelestica/sonic-buildimage/blob/master/platform/broadcom/sonic-platform-modules-cel/haliburton/script/50-ttyUSB-C0.rules#L11,L12) in the rule are not working as expect, but others works fine.

Could you please try below steps on your side?

  1. Unplug the usb connection between E1031 and console switch

I will try add something to this script tomorrow and get back to you.
I was wondering if there a hardware different or something cause this problem?
Here is my udev detail for ttyUSB0, but I think it should match the rule...

admin@sonic:~$ udevadm info -a -n /dev/ttyUSB0

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

I tried let the script output something to a file but no luck. Seems like these two rules are not triggered...
I will go deeper to the udev debug logs.. at the mean while?
@sandycelestica Which image are you using now? How about try master 492 on your side?

Interest founding:
The rule actually matched but the bash run failed due to permission issue. I thought the udev will using root to execute scirpt?

Mar 22 10:12:31 sonic systemd-udevd[32296]: '/bin/bash -c '/usr/local/bin/udev_prefix.sh clear''(err) '/bin/bash: /usr/local/bin/udev_prefix.sh: Permission denied'
Mar 22 10:12:31 sonic systemd-udevd[32296]: Process '/bin/bash -c '/usr/local/bin/udev_prefix.sh clear'' failed with exit code 126.

Mar 22 10:13:49 sonic systemd-udevd[32416]: '/bin/bash -c '/usr/local/bin/udev_prefix.sh C0-''(err) '/bin/bash: /usr/local/bin/udev_prefix.sh: Permission denied'
Mar 22 10:13:49 sonic systemd-udevd[32416]: Process '/bin/bash -c '/usr/local/bin/udev_prefix.sh C0-'' failed with exit code 126.

The script's attribute is shown below:

admin@sonic:~$ ls -a -l /usr/local/bin/udev_prefix.sh
-rw-r--r-- 1 root root 531 Mar 22 08:21 /usr/local/bin/udev_prefix.sh

After I executed below command manually, the udev rule script works fine.

admin@sonic:~$ sudo chmod +x /usr/local/bin/udev_prefix.sh

@sandycelestica could you share your script's attributes? May be we need to add execution permission to this script after copy it.

@sandycelestica Do you know where is the best place to add the chmod script? I try searched in this code repo, but seems like there are no sample...

Maybe platform-modules-haliburton.postinst?

Could you try add chmod scrpit in this file?

This script will run after install finished.
