Generate prototypes for syscall-implementing functions. Put them in <sys/sysproto.h> and use them (so far only) in kern/init_sysent.c. Don't put $Id in generated files. kern/syscalls.master: I had to add some new fields to describe some non-orthogonal names. E.g., the args struct for the syscall-implementing function foo() is usually named `foo_args', but for getpid() it is named `args'. sys/sysent.h: sy_call_t is still incomplete to hide a couple of warnings.

syshdr="../sys/syscall.h"
Add statements to generate a sys/syscall.mk file for inclusion during the libc/libc_r to automatically pick up syscall names on the assumption that default asm code needs to generated for them. In the up-coming changes to the libc makefiles, there is the option to provide a machine dependent asm source file which will turn off the automatic generation of the default. There is also an option to just stop code being generated for a syscall. In most cases, though, the default asm code is all that is required, so this change makes that the most convenient was to do business. Idea suggested by: bde

This commit fixes various 64bit portability problems required for FreeBSD/alpha. The most significant item is to change the command argument to ioctl functions from int to u_long. This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time.

Add statements to generate a sys/syscall.mk file for inclusion during the libc/libc_r to automatically pick up syscall names on the assumption that default asm code needs to generated for them. In the up-coming changes to the libc makefiles, there is the option to provide a machine dependent asm source file which will turn off the automatic generation of the default. There is also an option to just stop code being generated for a syscall. In most cases, though, the default asm code is all that is required, so this change makes that the most convenient was to do business. Idea suggested by: bde

This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change.

This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time.

Don't generate COMPAT_43 cruft if there are no COMPAT_43 syscalls. In particular, don't generate an include of "opt_compat.h" if it wouldn't affect anything we create. This will fix recent breakage of the ibcs2 LKM. The ibcs2 syscall files were not regenerated properly, so the LKM didn't break immediately when we started generating this extraneous include.

This commit fixes various 64bit portability problems required for FreeBSD/alpha. The most significant item is to change the command argument to ioctl functions from int to u_long. This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time.

Mega-commit for Linux emulator update.. This has been stress tested under 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.
