+IRC, #hurd, September 2010
+
+ <diegonc> when an application executes an out instruction in user mode, how is
+ kernel mode entered? general protection trap?
+ <youpi> some sort of trap, yes
+ <youpi> I'd rather think about illegal instruction, but yes
+ <diegonc> hm.. so to debug what happens inside that instruction I'll have to
+ break at the trap handler. Can I instruct kdb to stop only when a given task
+ caused the trap?
+ <youpi> applications usually don't trap, so what I usually do is to uncomment
+ the test at the end of user_trap() before the call to kdb_trap()
+ <diegonc> "if (debug_all_traps_with_kdb && .. " <- that test?
+ <youpi> yes
+ <youpi> so comment the test to make kdb_trap() called all the time
+ <diegonc> oh, I understand now :)

+
+ <youpi> jkoenig: from a quick read, your procfs implementation seems quite
+ simple, probably much more what I was expecting from Madhusudan (who probably
+ now hates you :) )
+ <youpi> jkoenig: is it not possible to provide a /proc/self which points at the
+ client's pid?
+ <pinotree> (also, shouldn't /proc/version say something else than "Linux"?)
+ <youpi> to make linux tools work, no :/
+ <youpi> kfreebsd does that too
+ <pinotree> really?
+ <youpi> yes
+ <youpi> (kfreebsd, not freebsd)
+ <pinotree> does kbsd's one print just "Linux version x.y.z" too, or something
+ more eg in a second line?
+ <pinotree> (as curiosity)
+ <youpi> % cat /proc/version
+ <youpi> Linux version 2.6.16 (des@freebsd.org) (gcc version 4.3.5) #4 Sun Dec
+ 18 04:30:00 CET 1977
+ <pinotree> k
+ <giselher> I had some problems with killall5 to read the pid from /proc, Is
+ this now more reliable?
+ <youpi> I haven't tested with jkoenig's implementation
+ [...]
+ <pinotree> looks like he did 'self' too, see rootdir_entries[] in rootdir.c
+ <youpi> but it doesn't point at self
+ <antrik> youpi: there is no way to provide /proc/self, because the server
+ doesn't know the identity of the client
+ <youpi> :/
+ <antrik> youpi: using the existing mechanisms, we would need another magic
+ lookup type
+ <antrik> an alternative idea I discussed with cfhammer once would be for the
+ client to voluntarily provide it's identity to the server... but that would
+ be a rather fundamental change that requires careful consideration
+ <antrik> also, object migration could be used, so the implementation would be
+ provided by the server, but the execution would happen in the client... but
+ that's even more involved :-)
+ <youpi> but we've seen how much that'd help with a lot of other stuff
+ <antrik> I'm not sure whether we discussed this on the ML at some point, or
+ only on IRC
+ <youpi> it "just" needs to be commited :)
+ <antrik> in either case, it can't hurt to bring this up again :-)
+
+ * IRC, #hurd, around October 2010
+
+ <pinotree> the only glitch is that files/dirs have the right user as
+ owner, but always with root group
