* Fixed unsigned longs that should have been vm_offset_t.bde1996-03-192-6/+10
| | | | | | | | | | vm_offset_t is currently unsigned long but should probably be plain unsigned for i386's to match the choice of minimal types to represent for fixed-width types in Lite2. Anyway, it shouldn't be assumed to be unsigned long. I only fixed the type mismatches that were detected when I changed vm_offset_t to unsigned. Only pointer type mismatches were detected.

| | | | | | | | To complete this, some extra state has to be kept somewhere so that the B38400 flag in Linux can be correctly translated to/from either 38400, 57600 or 115200. Submitted by: Robert Sanders <rsanders@mindspring.com>

| | | | | | | this code was not quite right (linux has a readdir and getdents syscall, with the same args. readdir only returns one entry and uses a mutant dirent structure. This code was also returning the mutant form for getdents as well. My fault for missing this before.)

* First attempt at FreeBSD & Linux ELF support.sos1996-03-104-71/+119
| | | | | | | | | | | | | | | | | Compile and link a new kernel, that will give native ELF support, and provide the hooks for other ELF interpreters as well. To make native ELF binaries use John Polstras elf-kit-1.0.1.. For the time being also use his ld-elf.so.1 and put it in /usr/libexec. The Linux emulator has been enhanced to also run ELF binaries, it is however in its very first incarnation. Just get some Linux ELF libs (Slackware-3.0) and put them in the prober place (/compat/linux/...). I've ben able to run all the Slackware-3.0 binaries I've tried so far. (No it won't run quake yet :)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* This is an extract of changes from what I am currently running...peter1996-02-162-114/+174
| | | | | | | | | | | | | | | | | | | | | | | - Optimise the linux a.out loading and uselib system calls so they take advantage of some of John's recent interface improvements. Basically, this means they make far less map changes than before. - Attempt to plug some potentially nasty kernel_map memory leaks.. - Improve support for QMAGIC libs (I only use QMAGIC (ie: a.out libraries from the slackware 3.0 dist) but this depends on other changes to enhance the /compat/linux support) - uselib goes out through a single exit as part of the resource tracking that I did when closing the resource leaks on errors. This could be cleaner than what I did, but making a 30-deep nested if/else was not my idea of fun, neither did I want to repeat the same code 30 times over for each failure possibility. I guess this function needs to be split into smaller functions to solve this. I've been running the Linux Netscape-2.0 (with Java) to test this, and apart from the long-standing problem with the missing scrollbars, it appears to still work as before with ZMAGIC libs (and the leaks).. However, I've been using it with mods for the signal trampoline code for native linux stack frames on signals and exterminated the blasted sigreturn printf() problem, so I can't be certain that there is not a dependency on something else.

| | | | | | | | | | | | | successfully run linux netscape 2.0b3 with a QMAGIC ld.so and libc/libm that I found on some linux machine that I _think_ is running slackware 3.0. There are still problems.. ld.so claims the libraries are the wrong format, but it still runs anyway.. :-/ The QMAGIC ld.so also screams about needing ld.so.cache, and running a linux ldconfig is quite educational. You soon learn to run "chroot /compat/linux /bin/ldconfig" where ldconfig is living in /compat/linux/bin. :-] (Lets just say that it puts loads of symlinks in /usr/lib otherwise :-)

* All:dg1995-11-063-41/+41
| | | | | | | | | | | | Changed vnodep -> vp for consistency with the rest of the kernel, and changed iparams -> imgp for brevity. kern_exec.c: Explicitly initialized some additional parts of the image_params struct to avoid bzeroing it. Rewrote the set-id code to reduce the number of logical tests. The rewrite exposed a mostly benign bug in the algorithm: traced set-id images would get ktracing disabled even if the set-id didn't happen for other reasons.

| | | | | | | | | | | | | | | | | | | | | | Submitted by: terry (terry lambert) This is a composite of 3 patch sets submitted by terry. they are: New low-level init code that supports loadbal modules better some cleanups in the namei code to help terry in 16-bit character support some changes to the mount-root code to make it a little more modular.. NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able to test those cases.. certainly mounting root of disk still works just fine.. mfs should work but is untested. (tomorrows task) The low level init stuff includes a total rewrite of init_main.c to make it possible for new modules to have an init phase by simply adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can be added to the kernel without editing any other files other than the 'files' file.

* First incarnation of our Linux emulator or rather compatibility code.sos1995-06-2512-0/+4413
This first shot only incorporaties so much functionality that DOOM can run (the X version), signal handling is VERY weak, so is many other things. But it meets my milestone number one (you guessed it - running DOOM). Uses /compat/linux as prefix for loading shared libs, so it won't conflict with our own libs. Kernel must be compiled with "options COMPAT_LINUX" for this to work.
