Hi Linux-netdev folks:
Could I export the socket security contexts to udp, tcp, raw,
unix file under /proc/net/?
If can not, Could you tell me where and how I should export this
information to?
The element sk_security of struct sock represents the socket
security context ID, which is inheriting from the process which
creates this socket most of the time.
but when SELinux type_transition rule is applied to socket, or
application sets /proc/xxx/attr/createsock, the socket security
context would be different from the creating process. on this
condition, the "netstat -Z" will return wrong value, since
"netstat -Z" only returns the process security context as socket
process security.
I want to fix "netstat -Z", but first the kernel must export this
information, like /proc/xxx/attr/current is the process security
context. So I have this requirement.
Expect your instruction.
Thanks.

Hi David:
Could you give some comments to my thought?
Singling me out directly is not helpful, I'm overloaded as it is
and am unlikely to reply to your query.
I didn't ask you to post here in order to just duplicate the same
problem that emailing me privately creates.
I asked you to post here so that any developer, not just me, could
reply.
