Diary for gilbou
Older diary entries for gilbou (starting at number 98):
spent time working on my gate. while my beloved netbsd doesn't have freebsd's jail, i combined systrace and veriexec. first one is a kind of firewall between kernel and userland developed by niels provos. so any call that isn't required by "normal" use of some binaries will be blocked. veriexec is used to load in a protected in-kernel hash table hashes of binaries (or scripts, anything that can be executable) and when a binary is to be executed, the kernel computes the hash and compares it to the md5 or sha-1 one stored in its table to allow or not execution of the binary. now i'd like to move security level to 1 (2 is too strict unless i move some stuff to mfs) and tie-down the box :)

i was quite surprised to see today an article from Forbes being published, where they explain that CA took a "Linux License" from SCO while it has been published for days on Groklaw and elsewhere that CA says it is false. Sent an email to Forbes asking them to check again and sent another one to CA asking them to clarify their position and have that Forbes article fixed. Title should not be "CA signed Linux license from SCO Group" but rather "SCO claims CA signed Linux license : CA denies". Please join ;)
elanthis : i know that ratings should be based on open source contribution but i'm bending it because i feel i should certify you. rules that don't bend will break :) and to be honest, the level i gave you is more related to what i saw by checking your diary than your musical skills, if any :D (i will give you a tablature of my last little tune if you ask, done it yesterday. pretty melancolic.)

elanthis : certified you for being a bass player (being one myself). i'm using an ibanez gsr205 (the cheap version of the sr-205 with 5 strings) and 150 W Trace Elliot Commando :)
bass players : good ! lars : baaaaaaaad !
fetched new cvs tree of /usr/src and applied patches. looks like the pagedaemon deadlocks are gone and with some help, bug 24443 will be closed.

while i was browsing google news i found that a on-line news site is using the red hat logo [backup copy] on a picture. i wonder how red hat is gonna react to the use of their logo by a graphist over the UN building to illustrate the british putting bugs to spy over Kofi Annan... ;) (cheers to red hat developers around)
netbsd 1.6.2 is finally out. if you got an ati card and like to use 80x50 i would suggest keeping with netbsd-current (the ZK from yesterday works fine and the pagedaemon deadlock seems gone for now). this release is dedicated to erik reid which is gone missing after a sailing incident (presumed dead). erik had done great work for netbsd over sgi mips, dri from xfree86 and management of the build lab.
rest in peace, erik :'(

today i discovered i am a "cross dominant". this means that while i'm right-handed, it is not my right-eye which is dominant but the left one (the dominant or lead eye is what does target acquisition. the other eye then follows the lead eye to the target to give stereoscopic vision). i have been firing weapons for years and i always had problems in having consistant results. i should be using left hand, not right one, to hold weapons and fire properly. and i found how to know about your own dominant eye in a programming book. life's irony...

several critical bugs have been found in the patch to ffs_softdep.c ; if you grabbed and applied it, please do the following. (1) grab the softdep.indirdep.diff from gilbou.shacknet.nu and put it in /usr/src/sys ; (2) grab the new diff named softdep.inodedep5.diff from the same spot and put it into /usr/src/sys/ufs/ffs/ (3) cd to /usr/src/sys/ufs then : cvs -z 6 -PAdCf ffs from there (you can remove ffs_softdep.c before the cvs, this is the one we patch) and cd to /usr/src/sys to apply the indirdep patch (patch -p0 < softdep.indirdep.diff). (4) from there we can apply the fixed patch; cd to /usr/src/sys/dev/ufs/ffs and patch -p0 < softdep.inodedep5.diff ; rebuild kernel and reboot :)
two patches are around to fix pagedaemon deadlocks. dont know if this will fix non-softdep deadlocks but i tortured my os and it went just fine. patches are to be applied from /usr/src/sys using patch -p0

running after some bug in the uvm. since post current-zg i get pagedeamon locks. not fun at all. i cant even tar zxf the zk sources i grabbed from another box to check the uvm source. i have spent the most part of night watching another box fetch that current-zk cvs and booting a 1.6zk doesnt help. pages free gets to 0, the pagedaemon starts paging out but in trying to do so, it needs (it seems) to allocate some buffer for writing to disk and since pages free == 0 uvm_wait is called and the deadlock occurs. someone else has the same trouble but only when using lfs and not ffs+softdep (but i get my own deadlocks on ffs+softdep which gets weird). the problem with that bug is it runs fast and my sleep just got past me ;)
all fine on 1.6zg it seems. zk not fixed yet. there are a few posts on current-users for now.
