Modified Files: src/sys/kern [netbsd-6-1]: uipc_syscalls.c Log Message: Pull up following revision(s) (requested by spz in ticket #996): sys/kern/uipc_syscalls.c: revision 1.163 PR/47591: Michael Plass: If the unix socket is closed before accept, unp->unp_conn will be NULL in PRU_ACCEPT, as called from sys_accept->so_accept. This will cause the usrreq to return with no error, leaving the mbuf gotten from m_get() with an uninitialized length, containing junk from a previous call. Initialize m_len to be 0 to handle this case. This is yet another reason why Beverly's idea of setting m_len = 0 in m_get() makes a lot of sense. Arguably this could be an error, since the data we return now has 0 family and length.
