Generate prototypes for syscall-implementing functions. Put them in <sys/sysproto.h> and use them (so far only) in kern/init_sysent.c.

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

Make sure we touch all the temporary files at startup, because we assume they were created later on. This is not the case when processing syscalls.isc in the ibcs2 area. (It generates no declarations, it's all either hidden (already prototyped elsewhere) or unimplemented).

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.

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.

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

Remove the MPSAFE keyword from the parser for syscalls.master. Instead introduce the [M] prefix to existing keywords. e.g. MSTD is the MP SAFE version of STD. This is prepatory for a massive Giant lock pushdown. The old MPSAFE keyword made syscalls.master too messy. Begin comments MP-Safe procedures with the comment: /* * MPSAFE */ This comments means that the procedure may be called without Giant held (The procedure itself may still need to obtain Giant temporarily to do its thing). sv_prepsyscall() is now MP SAFE and assumed to be MP SAFE sv_transtrap() is now MP SAFE and assumed to be MP SAFE ktrsyscall() and ktrsysret() are now MP SAFE (Giant Pushdown) trapsignal() is now MP SAFE (Giant Pushdown) Places which used to do the if (mtx_owned(&Giant)) mtx_unlock(&Giant) test in syscall[2]() in */*/trap.c now do not. Instead they explicitly unlock Giant if they previously obtained it, and then assert that it is no longer held to catch broken system calls. Rebuild syscall tables.

Remove the MPSAFE keyword from the parser for syscalls.master. Instead introduce the [M] prefix to existing keywords. e.g. MSTD is the MP SAFE version of STD. This is prepatory for a massive Giant lock pushdown. The old MPSAFE keyword made syscalls.master too messy. Begin comments MP-Safe procedures with the comment: /* * MPSAFE */ This comments means that the procedure may be called without Giant held (The procedure itself may still need to obtain Giant temporarily to do its thing). sv_prepsyscall() is now MP SAFE and assumed to be MP SAFE sv_transtrap() is now MP SAFE and assumed to be MP SAFE ktrsyscall() and ktrsysret() are now MP SAFE (Giant Pushdown) trapsignal() is now MP SAFE (Giant Pushdown) Places which used to do the if (mtx_owned(&Giant)) mtx_unlock(&Giant) test in syscall[2]() in */*/trap.c now do not. Instead they explicitly unlock Giant if they previously obtained it, and then assert that it is no longer held to catch broken system calls. Rebuild syscall tables.

Fixed the calculation of sy_nargs in sysent tables. We attempted to do this in awk using the hack of counting args of type off_t twice and args of all other types once. This is too simple to work. It gave benignly wrong results on alphas (off_t shouldn't be counted twice) and for svr4_sys_mmap64() on i386's (off64_t should be counted twice). It gave fatally wrong results for i386's with 64-bit longs (longs should be counted twice). The correct value for sy_nargs is easier to determine from the size of the args struct anyway, except for complications to make the generated code almost readable. Improved formatting of sysent tables by lining up the comments where possible.

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.

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.
