[tipc-discussion] Fwd: TIPC socket ( SOCK_SEQPACKET) cleanup issue

[prakash b. <ps1...@gm...>]

Hi John/Xin,Tung,

Any thoughts on my previous email? We are using tipc for our product for
quite a while and started facing this issue recently in a specific scenario
we launch strace to monitor another process.
Also is there any way to deny creation of another tipc socket with the same
tipc address ?  In our case applications need a unique tipc server socket.

Thanks and Regards,
Prakash

Hi all,



I am facing an issue while closing the TIPC server socket. In certain
scenarios, even after closing the server socket fd the ‘tipc socket list’
is still showing it as alive.

I am sure that the fd has been closed as the next socket creation request
gets the same fd from linux. Even when the process exits, the stale socket
entry is still present in the ‘tipc socket list’ and it vanishes only after
rebooting the system.

 Kernel version : 4.19.81

Socket type :      SOCK_SEQPACKET



Also, is there any way of finding out whether a tipc socket belongs to
which linux process ?



Would appreciate any help.


Thanks,

Prakash
