Analyze and fix the following issue in the Linux kernel code: NetLabel: Allow passing the LSM domain as a shared pointer
Problem Details: Smack doesn't have the need to create a private copy of the LSM "domain" when setting NetLabel security attributes like SELinux, however, the current NetLabel code requires a private copy of the LSM "domain". This patches fixes that by letting the LSM determine how it wants to pass the domain value. ...

Analyze and fix the following issue in the Linux kernel code: [SCTP]: IPv4 vs IPv6 addresses mess in sctp_inet[6]addr_event.
Problem Details: All IP addresses that are present in a system are duplicated on struct sctp_sockaddr_entry. They are linked in the global list called sctp_local_addr_list. And this struct unions IPv4 and IPv6 addresses. So, there can be rare case, when a sockaddr_in.sin_addr coincides with the corresponding part of t...
