there is no use for "bootdisk" variable parametrization
of /boot/boot and no point for the boot section with its
boot methods in the kernel configuration anymore. so
mkboot and boot$CONF.out are gone.
move the rules for bootfs.paq creation in 9/boot/bootmkfile.
location of bootfs.proto is now in 9/boot/bootfs.proto.
our /boot/boot target is now just "boot".
expand the list of files specified in bootfs.proto and use them
as dependencies to bootfs.paq rule. this way, bootfs.paq is
regenerated when the to be included files have been modified.
the utf8 buffers b1 where allocated from fbufalloc() which gives
us BUFSIZE bytes, but Xfid->count can be bigger than that. so just
emalloc() the requested number of bytes.
when converting from Runes to utf-8, we have to account for the
terminating '\0' byte snprint() places, so fix the maxrune number
calculation instead of using BUFSIZE+1 as buffer size.
A buffer can be overflowed in the init function of kbmap.c by using a filename of more than 112 characters.
sample output:
% cd /sys/lib/kbmap
% touch aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
% kbmap
kbmap 1974: suicide: sys: trap: fault write addr=0xa6a96510 pc=0x000011df
offending code is most likely the call to sprint in the init function of /sys/src/cmd/kbmap.c,
which in this case writes /sys/lib/kbmap/$file to a 128-bit buffer.
I'm willing to submit a patch for this myself along with a few minor improvements/fixes to kbmap
if I can figure out the nuances of doing so.

factotum is started in bootrc before the network is setup
(as we need it to negotiate wpa key for wifi). once, the network
is setup, the bootstrap authservers are passed in /net/ndb,
which factotum reads when doing bootstrap authdial. it does
this only when no authserver was specified earlier! but we
want net.rc to select the proper bootstrap authserver...
the $secstore variable takes precedence over $auth. as
there is no connection server yet, we have to select the set
of servers here and pass them to secstore with -s flag.
note that this will work if multiple addresses where
specified.
bug: Rnointerrupt was used on Vqueue.used.flags instead of
Vqueue.avail.flags.
introduce vqnotify() function that notifies the device
about available ring advancement.
avoid queue notifications there that can be slow by
checking Unonotify flag in Vqueue.used.flags.
keep track of the number of notifications in the queue.
- properly negotiate Fctrlrx feature bit for promisc and multicast.
- allow setting mac address with ea= option from plan9.ini
- dont read the isr register from ifstats() as it has the side effect of reseting isr status
- embedd the Vqueue array in the Ctlr structure avoiding indirection
- add a interrupt counter Vqueue.nintr for statistical purposes
- only read network status register if the feature has been negotiated
- change name to "virtio" as "ethervirtio" is kind of redundant
continue recursing when we get empty but non-negative answer
