===================================================================

PATCH:
    K210-026

SUMMARY:
	Change the Specialix multiport card driver's interrupt handler
	to clear interrupts before acknowledging them.  This should prevent 
	"lost intr" messages. Also declare some volatiles which were not.

===================================================================

PATCH:
    K210-027

SUMMARY:
	Changes in Apache 1.2b are exercising a problem in the
	kernel where sockets can get stuck in the FIN-WAIT-2
	state, if the final FIN never arrives from the other side.

	This patch ensures that when a process closes a socket
	that is in FIN-WAIT-2 state, a timer will be set.  If
	the final FIN never arrives, the timer will expire and
	the socket will be removed.

===================================================================

PATCH:
    U210-034

SUMMARY:
    This patch fixes a couple of security problems in support routines
    used by the BSD/OS 2.1 release version of the adduser and addgroup 
    programs.  Specifically, the new version ensures that the /etc/group
    file is not left writable by anyone other than root and it ensures
    that the temporary copy of the /etc/master.passwd file is never
    readable by anyone other than root (previously it could be read while
    adduser was rebuilding the database versions of the password file).

    This patch also fixes a problem in rmuser.  In the old version, 
    rmuser could occasionally remove more users than requested if they
    had the same UID as the user it was supposed to remove.

===================================================================

PATCH:
    U210-035

SUMMARY:
    This patch fixes some security problems the BSD/OS 2.1
    version of the talk daemon, /usr/libexec/ntalkd.
