syslog configuration for busybox (1.23)

[hemwant]

I am using a P5040 board, and currently using the utility syslogd from busybox which was available in rootfs package of BSP.I am facing a problem that the syslogd when run using following arguments

syslogd -b 5 -s 1000

the syslogd daemon fails to run pointing an error at line no 10. I am trying to generate 40 logs using the above configuration.

My syslog.conf file is mentioned below.

*.info /dev/console
local0.* /var/log/dwdm/cmlog
local1.* /var/log/dwdm/fmlog
local2.* /var/log/dwdm/pmlog

First you could use rootfs filesystem from Linux SDK 2.0 release, please download "Image: QorIQ Linux SDK v2.0 PPCE5500 IMAGE" from https://www.nxp.com/design/software/embedded-software/linux-software-and-development-tools/linux-sdk...

Then mount this ISO and use rootfs filesystem fsl-image-core-p5040ds.ext2.gz.u-boot in p5040ds folder.

$ busybox syslogd -b 5 -s 1000

$ cat /etc/syslog.conf

*.info /dev/console
local0.* /var/log/dwdm/cmlog
local1.* /var/log/dwdm/fmlog
local2.* /var/log/dwdm/pmlog
local3.* /var/log/dwdm/tilog
local4.* /var/log/dwdm/tpilog
local5.* /var/log/dwdm/tpnlog
local6.* /var/log/dwdm/log
local7.* /var/log/dwdm/esalog
kern.* /var/log/kern.log

This is working for my board.

But I need to configure log local0-local39, in that it shows error error at line 10 of syslog.conf.

[yipingwang]

The facilities local0 to local7 are "custom" unused facilities that syslog provides for the user.

[hemwant]

The facility of local0-local39 is working with P1022 board, but it is creating issue in P5040 board. We have also tried the same custom settings of syslog in our earlier 85xx board too.

Donot have any idea why this custom setting of local0-local39 is not working with P5040 board.

[yipingwang]

Please refer to https://man7.org/linux/man-pages/man3/syslog.3.html

       LOG_LOCAL0 through LOG_LOCAL7
              reserved for local use 

so only local0 to local7 are valid.

modification were done in busybox(1.23.2) source code to accomodate required changes.
