calling ioctl(SIOC[AS]IFADDR).
This allows the following:
ifconfig xx0 inet 1.2.3.1 netmask 0xffffff00
ifconfig xx0 inet 1.2.3.17 netmask 0xfffffff0 alias
ifconfig xx0 inet 1.2.3.25 netmask 0xfffffff8 alias
ifconfig xx0 inet 1.2.3.26 netmask 0xffffffff alias
but would (given the above) reject this:
ifconfig xx0 inet 1.2.3.27 netmask 0xfffffff8 alias
due to the conflicting netmasks. I would assert that it's wrong
to mask the EEXIST returned from rtinit() as in the above scenario, the
deletion of the 1.2.3.25 address will leave the 1.2.3.27 address
as unroutable as it was in the first place.

This change allows bootp to work with more than one interface, at the
expense of some rather ``wrong'' looking code. I plan to MFC this in
place of luigi's recent #ifdef BOOTP stuff that was committed to this
file in -stable, as that's slightly more wrong that this is.

Add the card name to the error message for the first initialisation
failure, giving us more info about what was actually discovered.
This code has been tested by Robert Suetterlin <robert@mpe.mpg.de>
to work on a PCI Xem card.
linker_search_module().
Without this, modules loaded from loader.conf that then try to load
in additional modules (such as digi.ko loading a card's BIOS) die
badly in the vn_open() called from linker_search_module().
It may be worth checking (KASSERTing?) that rootdev != NODEV in
vn_open() too.
mod_depend * (which may be NULL). The only consumer of this
function at the moment is digi_loadmoduledata(), and that passes
a NULL mod_depend *.
In linker_reference_module(), check to see if we've already got
the required module loaded. If we have, bump the reference count
and return that, otherwise continue the module search as normal.
is called.
- Change sysctl_out_proc() to require that the process is locked when it
is called and to drop the lock before it returns. If this proves too
complex we can change sysctl_out_proc() to simply acquire the lock at
the very end and have the calling code drop the lock right after it
returns.
- Lock the process we are going to export before the p_cansee() in the
loop in sysctl_kern_proc() and hold the lock until we call
sysctl_out_proc().
- Don't call p_cansee() on the process about to be exported twice in
the aforementioned loop.
p_pgrp since the pgrp locking went in. We also don't need it to check for
invalid values in the options argument to wait1(), so push Giant down
slightly.
with a back off. This was discovered when Luigi sent me code to
handle this for Etherboot. The Etherboot patch worked okay but
FreeBSD's tftpd had trouble handling it and would fail to transfer
the file since it would abort on send and not retry.

drivers with MI portions into the MI notes. Device drivers such as busses
like the isa, eisa, and pci devices are now in the MD NOTES section even
though they have some MI code. This will ensure that only the proper bits
of device drivers will be included due to the optional bits dependent on
the busses in sys/conf/files. This commit also takes the stance that since
hints are ignored in NOTES anyways, it is ok to include hints for a bus
that may not be present.
