chs 33fa5ccbbf many changes for COMPAT_LINUX:
- update the linux syscall table for each platform.
 - support new-style (NPTL) linux pthreads on all platforms.
   clone() with CLONE_THREAD uses 1 process with many LWPs
   instead of separate processes.
 - move the contents of sys__lwp_setprivate() into a new
   lwp_setprivate() and use that everywhere.
 - update linux_release[] and linux32_release[] to "2.6.18".
 - adjust placement of emul fork/exec/exit hooks as needed
   and adjust other emul code to match.
 - convert all struct emul definitions to use named initializers.
 - change the pid allocator to allow multiple pids to refer to the same proc.
 - remove a few fields from struct proc that are no longer needed.
 - disable the non-functional "vdso" code in linux32/amd64,
   glibc works fine without it.
 - fix a race in the futex code where we could miss a wakeup after
   a requeue operation.
 - redo futex locking to be a little more efficient.

njoly 5affb2e50a Make sysctl(2) fails with ENOTDIR (instead of EINVAL) for invalid mib
vector length.

ad 92ce8c6a3d Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

ad 0efea177e3 Remove LKMs and switch to the module framework, pass 1.
Proposed on tech-kern@.

ad 77e0b2120f Patch up sysctl locking:
- Lock processes, credentials, filehead etc correctly.
- Acquire a read hold on sysctl_treelock if only doing a query.
- Don't wire down the output buffer. It doesn't work correctly and the code
  regularly does long term sleeps with it held - it's not worth it.
- Don't hold locks other than sysctl_lock while doing copyout().
- Drop sysctl_lock while doing copyout / allocating memory in a few places.
- Don't take kernel_lock for sysctl.
- Fix a number of bugs spotted along the way

dsl 7e2790cf6f Convert all the system call entry points from:
int foo(struct lwp *l, void *v, register_t *retval)
to:
    int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.

dsl 28bae79b27 ANSIfy most of the function definitions in sys/compat (but not ndis).
All by the magic of sed ...

ad 63c4506184 Changes to make ktrace LKM friendly and reduce ifdef KTRACE. Proposed
on tech-kern.
2007-08-15 12:07:23 +00:00
dsl d364d308c7 Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx). 2007-03-18 21:38:32 +00:00
ad b07ec3fc38 Merge newlock2 to head. 2007-02-09 21:55:00 +00:00
manu 63ac93df54 Add sysctl tracing to emulations.
While we are there, fix a bug in FreeBSD sysctl emulation: use copyin for
moving data to the kernel
2006-09-23 22:11:59 +00:00
manu 4d5f807455 Fix linux32_sys_sysctl, it was horribly broken. 2006-09-05 17:12:19 +00:00
manu ee0c5b44de Add initial (but unfinished) COMPAT_LINUX32 for amd64. This is good enough so
that the i386 license manager part of amd64 version of Fluent works.

While I'm here, add SysV IPC to COMPAT_LINUX/amd64
