Here is my current patch series.
The first three were originally developed to fix several issues in a
fbsd-current checkout of Nov 7th 2006.
The last two patches were added when I updated and retested against a checkout
of -current, May 8th, 2007.
Yesterday I updated my test system with cvsup and rebased the patches (only
one minor conflict). I am still in the middle of make buildworld and that will
probably take a while, but the change was pretty trivial so I expect it will
work as well as when I tested on May 8th. And on the bright side, it can't do
much worse compared to right now, which is to crash or panic the kernel as
soon as either /dev/cfs0 is opened or the Coda filesystem is mounted.
Short summary,
[1/5] Avoid crash when opening Coda's control device.
[2/5] mount coda failed because we failed to match on the device
operations.
[3/5] When opening a file in /coda ask userspace to pass an opened file
descriptor instead of device/inode number pair.
[4/5] insmntque panics the kernel when passed a NULL mount, so we should
not pass that.
[5/5] ioctls on a character device fails before it gets passed on to the
file system. Change the type of the control object to a regular file.
The diffs are taken from a repository that only tracks /usr/src/sys/coda,
they should apply cleanly with the following command,
patch -d /usr/src/sys/coda -p1 < patchN
