This should prevent "lost intr" messages. Also declare some volatiles which were not. md5 checksum: 7f6303c3d2ccba70b995806335684836 K210-026 =================================================================== 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. md5 checksum: 49df19100ebf60aebd27a27305b6ef8e K210-027 =================================================================== 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. md5 checksum: 8e2ff944f23b2bf132b7ac5bf97db94a U210-034 =================================================================== PATCH: U210-035 SUMMARY: This patch fixes some security problems the BSD/OS 2.1 version of the talk daemon, /usr/libexec/ntalkd. md5 checksum: 7d2e6e3d424c6a1d9af4f78d3bea870b U210-035 =================================================================== -- [ /tom haapanen -- tomh@metrics.com -- software metrics inc -- waterloo, ont ] [ "any sufficiently advanced technology ] [ is indistinguishable from magic" -- arthur c. clarke ]
