netscape-2.0 for Linux running all the Java stuff. The scrollbars are now
working, at least on my machine. (whew! :-)
I'm uncomfortable with the size of this commit, but it's too
inter-dependant to easily seperate out.
The main changes:
COMPAT_LINUX is *GONE*. Most of the code has been moved out of the i386
machine dependent section into the linux emulator itself. The int 0x80
syscall code was almost identical to the lcall 7,0 code and a minor tweak
allows them to both be used with the same C code. All kernels can now
just modload the lkm and it'll DTRT without having to rebuild the kernel
first. Like IBCS2, you can statically compile it in with "options LINUX".
A pile of new syscalls implemented, including getdents(), llseek(),
readv(), writev(), msync(), personality(). The Linux-ELF libraries want
to use some of these.
linux_select() now obeys Linux semantics, ie: returns the time remaining
of the timeout value rather than leaving it the original value.
Quite a few bugs removed, including incorrect arguments being used in
syscalls.. eg: mixups between passing the sigset as an int, vs passing
it as a pointer and doing a copyin(), missing return values, unhandled
cases, SIOC* ioctls, etc.
The build for the code has changed. i386/conf/files now knows how
to build linux_genassym and generate linux_assym.h on the fly.
Supporting changes elsewhere in the kernel:
The user-mode signal trampoline has moved from the U area to immediately
below the top of the stack (below PS_STRINGS). This allows the different
binary emulations to have their own signal trampoline code (which gets rid
of the hardwired syscall 103 (sigreturn on BSD, syslog on Linux)) and so
that the emulator can provide the exact "struct sigcontext *" argument to
the program's signal handlers.
The sigstack's "ss_flags" now uses SS_DISABLE and SS_ONSTACK flags, which
have the same values as the re-used SA_DISABLE and SA_ONSTACK which are
intended for sigaction only. This enables the support of a SA_RESETHAND
flag to sigaction to implement the gross SYSV and Linux SA_ONESHOT signal
semantics where the signal handler is reset when it's triggered.
makesyscalls.sh no longer appends the struct sysentvec on the end of the
generated init_sysent.c code. It's a lot saner to have it in a seperate
file rather than trying to update the structure inside the awk script. :-)
At exec time, the dozen bytes or so of signal trampoline code are copied
to the top of the user's stack, rather than obtaining the trampoline code
the old way by getting a clone of the parent's user area. This allows
Linux and native binaries to freely exec each other without getting
trampolines mixed up.
Close the ip-fragment hole.
Waste less memory.
Rewrite to contemporary more readable style.
Kill separate IPACCT facility, use "accept" rules in IPFIREWALL.
Filter incoming >and< outgoing packets.
Replace "policy" by sticky "deny all" rule.
Rules have numbers used for ordering and deletion.
Remove "rerorder" code entirely.
Count packet & bytecount matches for rules.
Code in -current & -stable is now the same.
to enable IP forwarding, use sysctl(8). Also did the same for IPX,
which involved inventing a completely new MIB from whole cloth (which
I may not quite have correct); be aware of this if you use IPX forwarding.
(The two should never have been controlled by the same option anyway.)
or deleted.
Motivated by: `int doclusteread = 1;' in ext2_vnops.c redefined
doclusterread if DEBUG is defined, so it could not have worked.
This was fixed by staticizing things before it caused problems.
I didn't find any more cases like this.
LINT: add a couple of new/missing/undocumented options
files.i386: add linux code so that you can compile a kernel with static
linux emulation ("options LINUX")
i386/*: use #if defined(COMPAT_LINUX) || defined(LINUX) to enable static
support of linux emulation (just like "IBCS2" makes ibcs2 static)
The main thing this is going to make obvious, is that the LINUX code
(when compiled from LINT) has a lot of warnings, some of which dont look
too pleasant..
allow one EISA/ISA/PCI/VL Buslogic controller to be probed. The driver
is almost fully dynamic. It just needs some kdc work and for the SCSI code
to stop passing unit numbers up in the scsi_xfer struct.
o Add signed/unsigned functionality to the matrox meteor device driver.
o Apply a few fixes to the sound driver.
o Add a ``SPIGOT_UNSECURE'' compile time definition so, if one defines
SPIGOT_UNSECURE in their conf file, then they can use the spigot w/o
root. There is a warning that this allows users access to the IO
page which is probably not secure.

this driver hasn't been checked but as a separate module, bringing it in won't
break anything else and it't the best way of testing it......

This is a bulk mport of Mike's IPX/SPX protocol stacks and all the
related gunf that goes with it..
it is not guaranteed to work 100% correctly at this time
but as we had several people trying to work on it
I figured it would be better to get it checked in so
they could all get teh same thing to work on..
Mikes been using it for a year or so
but on 2.0
more changes and stuff will be merged in from other developers now that this is in.

Extend test coverage:
Add and enable undocumented options TCPDEBUG, COMPAT_LINUX and IBCS2.
Add but disable (broken) pseudo device tb.
Add and enable pseudo devices su, ssc.
Add but disable (broken) devices sscape0, trix0.
Add and enable device bqu0.
had a 2.1 tag, thus sending these two changes into the 2.1 branch instead
of -current. Argh. I may bring these changes into the 2.1 anyway (they're
benign there) so I'm not going to admin them out of 2.1 for the time
being.
