- Split 4.3BSD ifioctl stuff into its own file.
- Remove some ifdefs that include small fragments of vfs compat code
which are difficult to relocate elsewhere.
- Socket layer becomes MP safe.
- Unix protocols become MP safe.
- Allows protocol processing interrupts to safely block on locks.
- Fixes a number of race conditions.
With much feedback from matt@ and plunky@.
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.
that use struct ifreq which have not been explicitly versioned.
If someone feels like fixing it with a list aproach, I think below is
a complete list - the one used in the previous version missed a lot of them.

once the 'address' has been copied into an mbuf.
Add extra flags for 'struct msghdr.msg_flags' to indicate that the address
and control are already in mbufs, and that the uio structure is in userspace
for sending data, rename sendit() to do_sys_sendmsg() to ensure no old code
passes in random flags.
Changes to compat code to use new functions - removing some stackgap use.
Fix a 'use after free' in compat_43_sys_recvmsg.

svr4_stream.c ought to be generated from svr4_32_stream.c during the build.
compatibility with the older ioctls. This avoids stack smashing and
abuse of "struct sockaddr" when ioctls placed "struct sockaddr_foo's" that
were longer than "struct sockaddr".
XXX: Some of the emulations might be broken; I tried to add code for
them but I did not test them.
Patch by Slava Semushin <slava.semushin@gmail.com>
Again, this was tested by comparing obj files from a pristine and a patched
source tree against an i386/ALL kernel, and also for src/sbin/fsck_ffs,
src/sbin/fsdb and src/usr.sbin/makefs. Only changes in assert() line numbers
were detected in 'objdump -d' output.
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
arrange things as needed. Unfortunately, the check in sockargs()
have to stay, since 4.3BSD bind(2), connect(2) and sendto(2) were
not versioned at the time :(
This code was tested to pass regression tests.
is supposed to point directly to struct mbuf or struct sockaddr in kernel
space as appropriate, rather than being a pointer to memory in userland.
This is to be used by compat/* when emulation needs to wrap
send{to|msg}(2)/recv{from|msg}(2) and modify the passed struct
sockaddr.
* the first one would cause an unnecessary malloc() of iovec storage for
a msg_iovlen of UIO_SMALLIOV although the required amount of memory has
been allocated on the stack.
* the second one would cause a recvmsg() or sendmsg() with a msg_iovlen of
UIO_MAXIOV to fail with EMSGSIZE, which is also a violation of XNS5.
- Created compat_util.c and compat_util.h to be used by the compatibility
modules, so they don't duplicate the same code.
- Added prototypes to the stackgap allocation routines.
