Hi All,
I am having tcp server , which is running with non root user.
Trying to set the QOS on the accepted socket.
Currently it returns Permission Error as errno "Error:Operation not permitted". Trying to mark the packet with mark EE.
Observation is IPTOS and IP_PRIORITY is working fine with non root user . Only with SO_MARK I am seeing this error.
my kernel version is 4.19.183.
Any other way I can triage more like , what exact the reason for not giving the permission . ( is it only because of non root or any other reason ). I mean like any specific logs which can be referred.
Appreciate your time in reading this thread.
In case any inputs on this related , please share it.
Thanks
