Windows 95 after rebooting FreeBSD without power off. In PC-98
system, reboot mode is set via I/O port 0x37 in cpu_reset(), and
accessing of this port is the reason of the problem. To avnoid the
fault, current status of reboot mode should be checked before
accessing the I/O port.
that local APIC should be disabled in UP system. However, some of old
BIOS does not disable local APIC, and virtual wire mode through local
APIC may cause int 15.
submitted ioctl to clear the video buffer
prior to starting video capture
Amancio : clean up yuv12 so that it does not
affect rgb capture. Basically, fxtv after
capturing in yuv12 mode , switching to rgb
would cause the video capture to be too bright.
1.32 disable inverse gamma function for rgb and yuv
capture. fixed meteor brightness ioctl it now
converts the brightness value from unsigned to
signed.
1.33 added sysctl: hw.bt848.tuner, hw.bt848.reverse_mute,
hw.bt848.card
card takes a value from 0 to bt848_max_card
tuner takes a value from 0 to bt848_max_tuner
reverse_mute : 0 no effect, 1 reverse tuner
mute function some tuners are wired reversed :(
are unaligned for access by the alpha, so copy the value to a variable
that is aligned.
When checking the returned data, be careful to avoid confusing the
size of the icmp header with the size of a timeval. On i386 these
are both 8, but on alpha, a timeval is 16 bytes. This means that
a packet sent from an alpha contains 48 bytes of data, not 56 like
on i386.
recently in BUGTRAQ. The set_input_fragment() routine in the XDR record
marking code blindly trusts that the first two bytes it sees will in fact
be an actual record header and that the specified size will be sane. In
fact, if you just telnet to a listening port of an RPC service and send a
few carriage returns, set_input_fragment() will obtain a ridiculously large
record size and sit there for a long time trying to read from the network.
A sanity test is required: if the record size is larger than the receive
buffer, punt.
recently in BUGTRAQ. If a stream oriented transport fails to properly decode
an RPC message header structure where there should be one, it should mark
the stream as dead so that the connection will be dropped.
dereferenced. This is because 'SP' is only initialized via 'newterm()'
(which is not required if you are going to interact with the 'terminfo'
database without using 'ncurses').

Define a parameter which indicates the maximum number of sockets in a
system, and use this to size the zone allocators used for sockets and
for certain PCBs.
Convert PF_LOCAL PCB structures to be type-stable and add a version number.
Define an external format for infomation about socket structures and use
it in several places.
Define a mechanism to get all PF_LOCAL and PF_INET PCB lists through
sysctl(3) without blocking network interrupts for an unreasonable
length of time. This probably still has some bugs and/or race
conditions, but it seems to work well enough on my machines.
It is now possible for `netstat' to get almost all of its information
via the sysctl(3) interface rather than reading kmem (changes to follow).
execution is usually unnecessary in BSD Makefiles because BSD make
invokes shells with -e. Using it to give conditional execution is
often wrong in BSD makefiles because BSD make joins shell commands
when invoked in certain ways (in particular, as `make -jN'). Example
makefile:
---
clean:
cd /
false && true
rm -rf * # a dangerous command
---
This should terminate after the `false && true' command fails, but
it doesn't when the commands are joined (`false && true' is a non-
simple command, so -e doesn't cause termination). The b-maked version:
---
clean:
cd /
false; true
rm -rf * # a dangerous command
---
terminates after the `false' command fails (`false' is a simple
command, so -e causes termination). However, for versions of
make like gnu make that don't invoke shells with -e, this change
completely breaks the makefile.
This is one of the fixes for the bug suite that caused `make world'
to sometimes put raw cpp output in .depend files. Building of cc
sometimes failed, but the failure did not terminate the build
immediately, and various wrong versions of the cc components were
used until one was wrong enough to cause a fatal error.
any case.
It makes no difference for anon account (since chroot already makes it GMT),
but if you do mirror with special non-anon login, in old variant
your mirror will be wholy retransmitted twice in the year due to
time zone changes (/etc/localtime plays bad role here)
that prevent the programs from being linked static (duplicated
symbols).
Other programs depend on kernel internals. These will have to wait
for a custom alpha kernel. For now, let's just make the build safe.
Notes:
- We no longer use -fgnu-runtime in bsd.lib.mk, since it is the default
and bsd.lib.mk is the wrong place to override it.
- Gnu C doesn't have a special compiler driver for Objective C like it
does for C++. The defaults are suitable for Gnu C. Use `OBJCLIBS='
in /etc/make.conf for POC.
