[9fans] 9vx - prerequisites

[Lucio De Re]

I'm not familiar enough with Linux and APT to figure this one out:
what are the prerequisites for 9vx that are not intrinsically met by a
standard UBUNTU installation?  The immediate need is related in some
way to x11-draw, but that is not the name of an apt package.

[9fans] double posting

[Steve Simon]

I don't know who is control of the reflector for this list but I have been 
seeing
duplicated posts for the last couple of days.

I noticed on 9srv that I received duplicates, buy gmail hasn't show
any of them (or I don't remember reading them). It started on the 24th.

[9fans] acid aggr assignment

[erik quanstrom]

after a quick look around, i can't see an easy way to do this.
perhaps i have just misread the docs.

i have an aggr P, p=(P)x.  i want to set p.i=1, unfortunately
p.i is a value not an address so that doesn't work.  how do i do this?

You may wish to install the apt-file package, then you could do
apt-file search x11-draw in order to know which package provides it.

In addition to what has been already said, if you need virtual
ethernet devices you will need libpcap-dev in order to build 9vx with
pcap support.

[9fans] acid hack

[erik quanstrom]

i was having some trouble with a user program that was setting
Proc.debugmem.  for various reasons it was easier to hack the
kernel than hack the program in question.  so i thought i'd
just get into the kernel and set Proc.debugmem = 0.

obviously, this doesn't work out-of-the-box, so i modified the
kernel a bit to allow writes.  (relax, it's normally compiled out ☺)
and it was easy enough to write a bit of acid

p = (Proc)procalloc.ht[mypid % 128]
while(p != 0  p.pid != mypid) do p = p.pidhash

but how to set p.privatemem=0?  a first cut was to take

p\X + y

where y was determined by grepping around in the kernel acid
file.  but this really is ugly, and hard to hand off to somebody else
as a solution.  since - is something wierd and . is taken, i used
the syntax

x·y ≡ x\X + y

where y is the same value as before, e.g. offsetof(Proc, privatemem)

so now i can say

*(p·privatemem) = 0

before jeering too much, consider that this also allows one to set
aggr members in user programs.  if you've got another solution that
looks better, doesn't require a rune, etc. i'd be happy to hear it.

so perhaps i'll define the acid prize.  5 euros to the first person
to post a convincingly improved approach to the list.

Now, that's a piece of useful information, thank you.  APT is so
unhelpful regarding trying to get any information out of it.
