Patch

前几天有人问 FreeBSD 的 top(1) 如何能够显示不同 CPU 的占用情况。这是 patch 过之后的输出：

FreeBSD 8 中已经包含了这个功能。

Here is a patchset that updates cvs to 1.11.22, which means some bugfixes. I have not throughly tested it yet.

Note that a final update would be more complex than this one.

提了个patch不到10分钟就上去了，赞一个……

I have finished a preliminary patchset based on Pawel’s (kern/54604), which will make ps -e usable under FreeBSD’s recent versions, without having procfs mounted.

My patchset has introduced reduced security IMO (due to my merge and rooted from recent removal of ps_argsopen sysctl, I’m not sure why this change has been taken place) so I will have to review the code more carefully. Maybe I need to introduce more sysctl?

I have promised to FreeBSD doceng team that we will have www/ and doc/ preliminary patchset ready this week and it is likely to be finished before the weekend :-)

Finally the phpBB issue was posted to BugTraq, as a follow-up to the original post by Wang.

Today Microsoft has released four critical security updates, their KB numbers are: 835732, 828741, 837009, 837001.
