ifp->if_output() functions. This way, initial implementations of
rt_output functionality can just lazily use if_output until customized
versions are written.
(mask,value) in the tree, don't immediately return EEXIST. Instead, check
to see if the pre-existing route was generated by protcol-cloning. If so,
then it is OK to simply blow away the old route and re-attempt the insertion.
If not, then fall back to the same error code as before.
a few new wrinkles for MTU discovery which tcp_output() had better
be prepared to handle. ip_output() is also modified to do something
helpful in this case, since it has already calculated the information
we need.
This is truly a hack. The idea is taken from the Linux ibcs2 emulator.
To use this feature, you must use the option,
options SPX_HACK
in your config.
Also, in /compat/ibcs2/dev, you must do:
lrwxr-xr-x 1 root wheel 9 Oct 15 22:20 X0R@ -> /dev/null
lrwxr-xr-x 1 root wheel 7 Oct 15 22:20 nfsd@ -> socksys
lrwxr-xr-x 1 root wheel 9 Oct 15 22:20 socksys@ -> /dev/null
crw-rw-rw- 1 root wheel 41, 1 Oct 15 22:14 spx
Do NOT use old socksys driver as that has been removed.
This hack needs /compat/ibcs2/dev/spx to be any device that does NOT
exist/configured (so the now non-existant spx major/minor works fine).
When an open() is called, the error ENXIO is checked and then the
path is checked. If spx open detected, then a unix socket is opened
to the hardcoded path "/tmp/.X11-unix/X0".
As the Linux hacker author mentioned, the real way would be to detect
the getmsg/putmsg through /dev/X0R and /dev/spx. Until this true
solution is implemented (if ever), I think this hack is important
enough to be put into the tree, even though I don't like it dirtying
up my clean code (which is what #ifdef SPX_HACK is for).
Currently, the emulator defaults to returning "FreeBSD" as the system
name, release "3.2", and version "2.0". Some programs want to make
sure they are on a SYSV 3.2 system and check for 3.X release number.
Use the following defines to override the defaults:
IBCS2_UNAME_SYSNAME
IBCS2_UNAME_RELEASE
IBCS2_UNAME_VERSION
(should be string)
for system name, release, and version, respectively. This allows
someone to compile the emulator into the kernel so it can pretend
to be a specific system if needed.
Require the state of the configuration enable bits to be OFF assuming
that the BIOS left them that way, as it should anyway to avoid bad things
to happen.
The tests themselves are copied from the previous release, with the
exception of CONF1_ENABLE_MSK1 having the LSB set. This bit should be
read back as '0', since only DWORD addresses are legal.
This directory is for tools.
A tool is something which is sometimes useful, and doesn't fit any of the

This directory is for test programs.
A test program is one that will excercise a particular bit of the system
and try to break it and/or measuring performance on it.

A diagnostic program is one that will inform you that something is wrong

I tried to solve the problem of IDE probing compatibility in this version.
When compiled without an ATAPI option, the wd driver is
fully backward compatible with 2.0.5. With ATAPI option,
the wdprobe becomes strictly weaker. That is, if wdprobe works
without ATAPI option, it will always work with it too.
Another problem was with the CD-ROM drive attached as a slave
in the IDE bus, where there is no master. All IDE CD-ROM
drives are shipped in slave configuration, and most users
just plug them in, never thinking about jumpers.
It works fine with ms-dos and ms-windows, and this
version of the driver supports it as well.
The eject op can now load disks. Just repeat it twice,
and the disk will be ejected and then loaded back.
The disc cannot be ejected if it is mounted.
