Considering of porting ReiserFS4 to FreeBSD

2004-09-10 05:17 | *nix and Win32 Kernel

Finally I am thinking about porting ReiserFS4 to FreeBSD. The current ReiserFS is GPL’ed so it should not get into FreeBSD kernel, but I think it might be OK to leave it as a ports of kernel module (like pf).

Matthew Dillon's opinion on FreeBSD's Networking Subsystem

2004-09-10 00:39 | *nix and Win32 Kernel

To quote his “I would recommend against per-thread caches. Instead, make the per-cpu caches actually *be* per-cpu (that is, not require a mutex).”

Then, he has pointed out that there is potential problems in FreeBSD’s SLAB allocator which is different from DragonFly’s. (Not too surprisingly, he is again advertising his IPI message approach).

bin/71404

2004-09-06 23:53 | *nix and Win32 Kernel

About 9 Years ago, FreeBSD has introduced a functionality in sysinstall(8)’s partition editor, which is to mark a partition “active”.

However, unfortunatelly, the implementation contained a flow from the day 0 it was introduced. Sysinstall(8) depends on user’s sanity not to mark only one partition as active on one disk.

This turned out to a potential damage of disk partition table. With two partitions marked “ACTIVE”, you will get the following message:

“Invalid partition table.”

Then system will halt.

It’s here:

This is mostly equal to 5.3-BETA3.

ps(1) patch for FreeBSD 6-CURRENT

2004-08-23 09:11 | *nix and Win32 Kernel

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?

FreeBSD 5-STABLE branched

2004-08-19 03:26 | *nix and Win32 Kernel

Now we have RELENG_5 branched, and HEAD is now 6.0-CURRENT.

delphijfork will be a mixture of RELENG_5 and HEAD for recent days. I will build a RELENG_5’ifyed version so the code is fresh enough for RELENG_5.

delphijfork 20040814 released

2004-08-15 08:29 | *nix and Win32 Kernel

I was quite busy recently however it is time to release delphijfork as 5-STABLE is imminent.

As always, it can be obtained from ftp://ftp.freebsdchina.org/pub/china_ports/delphijfork.

In this release, I have added a (untested) ATA workaround for CD-ROMs that is not installed in correct slot.
