- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
$INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.
this makes "prefix" actually work in a usable manner, and now i can move
on to fixing compiler warnings (errors) in the ESP code. :)
to file specifications. The prefixes are arranged in a stack, and
nest, so that file, object, and include specifications are normalized,
and all end up relative to the kernel compile directory.
For example, in the kernel config file:
# Pull in config fragments for kernel crypto
prefix ../crypto-us/sys # push it
cinclude "conf/files.crypto-us" # include it if it's there
prefix # pop it
and in files.crypto-us:
file netinet6/esp_core.c ipsec & ipsec_esp
file netinet6/esp_output.c ipsec & ipsec_esp
file netinet6/esp_input.c ipsec & ipsec_esp
...generates the following in the kernel Makefile:
$S/../crypto-us/sys/netinet6/esp_core.c \
$S/../crypto-us/sys/netinet6/esp_output.c \
$S/../crypto-us/sys/netinet6/esp_input.c \
By placing this all in the kernel config file, all the magic involved in
reaching into non-standard kernel source directories is placed into a file
that the user is expected to edit anyway, and reasonable examples (and
sane defaults, for typical source checkouts) can be provided.
file, conditional on their existence. For example:
[ in ../conf/GENERIC ]
cinclude "../crypto-intl/sys/conf/files.crypto-intl"
This required a change to the files.* grammar; pseudo-device in that
context has been changed to defpseudo, to avoid a conflicting rule
for pseudo-device in the kernel config files.
The same grammar change allows vendors to ship files.* files for
commercial drivers, rather than diffs to e.g. files.pci, i.e.:
include "arch/i386/pci/files.zap"
zap* at pci? device ? function ?
Where files.zap might contain:
device zap: ether, ifnet, arp, mii
attach zap at pci
object arch/i386/pci/zap.o zap
rip6query: RIPng query (similar to ripquery)
NOTE: we usually do not run route6d on end nodes at startup (rtsol should do
the trick). So I figured that route6d can be in /usr/sbin, not in /sbin
(routed is in /sbin). Correct me if I'm wrong.
(the style is the rough consensus among v6 implementers so it will be
the standard style)
