Re: [9fans] ethervirtio
Did anyone compare throughput, pps, etc. with the same on standard rtl or intel emulated cards?

Since QEMU (#S/sd00) and GCE (#S/sd01) use a different controller name, the plan9.ini will let you choose between QEMU and GCE. Here is the output of the GCE console: http://9legacy.org/9legacy/doc/gce/console You can easily create a Plan 9 disk or cd image yourself by applying the patches and following the instructions on: http://9legacy.org/9legacy/doc/gce/notes The next step is to fix the DHCP client in ip/ipconfig. -- David du Colombier

Re: [9fans] dbus fun ;-)
I looked at dbus for an embedded Linux project at work a few years ago, I ran screaming. I convinced them to use an ascii protocol through a virtual file. much nicer. -Steve On 4 Dec 2014, at 15:15, Enrico Weigelt, metux IT consult enrico.weig...@gr13.net wrote: http://gentooexperimental.org/~patrick/weblog/archives/2014-11.html#e2014-11-23T09_26_01.txt -- Enrico Weigelt, metux IT consulting +49-151-27565287
[9fans] Debian bug 737206 - rc shell uses insecurely /tmp
Hello, I make you pass an open bug report on the Debian bts about rc. I do not know to whom I should speak. The code comes from 9base, who just plan9port, etc. Here is the report [1]: Package: 9base Version: 1:6-6 Severity: important Tags: security Murray McAllister from Red Hat Security Response Team discovered that rc creates temporary files in an insecure way: $ strace -o '| grep /tmp' ./test-heredoc open(/tmp/here217f., O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = 5 open(/tmp/here217f., O_RDONLY|O_LARGEFILE) = 5 moo unlink(/tmp/here217f.)= 0 As you can see, the filenames are easily predictable, and the O_EXCL flag is missing.

Obviously the version for Unix will have to change its generation scheme to fit in.
[9fans] Is the go9p project still maintained?
Hi Just wondering if the project https://code.google.com/p/go9p/ is actively maintained these days? I used it in my project, but fixing issue 30 broke it. I opened issue 34 https://code.google.com/p/go9p/issues/detail?id=34 which also contains a suggested patch. No response since then. If the project's active repo moved please let me know, I'll resubmit the issue there. If the project is not maintained anymore I'll take care of it in my project's local repo. Thanks. -- Dmitry Golubovsky Anywhere on the Web

Aren't they talking about rc when running on their operating system? sl

I see no difference between: a || b and a || (a b) which is (a || a) (a || b) a || (a b) is actually just a fancier way to write a. if a is true, the result is true, if a is false, the result will be a b, however, as a is already false, it's false. in go9p.patch, the suggested change is actually from a || b to a || (b a), this is slightly different. But it's still just a fancier way to write a.
