MFC: Fix the ABI wrappers to use kern_fcntl() rather than calling

2004-09-03T15:30:21+00:00

fcntl() directly and mark related ABI syscalls as MP safe.

MFC: (1.52) only translate control message if we're sure it's valid.

Changes to MI Linux emulation code necessary to run 32-bit Linux binaries

2004-08-16T07:28:16+00:00

on AMD64, and the general case where the emulated platform has different
size pointers than we use natively:
- declare certain structure members as l_uintptr_t and use the new PTRIN
  and PTROUT macros to convert to and from native pointers.
- declare some structures __packed on amd64 when the layout would differ
  from that used on i386.
- include  instead of 
  if compiling with COMPAT_LINUX32. This will need to be revisited before
  32-bit and 64-bit Linux emulation support can coexist in the same kernel.
- other small scattered changes.

This should be a no-op on i386 and Alpha.

I missed two pieces of the commit to this file. Robert has already

2004-07-18T09:26:34+00:00

added one, this adds the other.

Remove 'sg' argument to linux_sendto_hdrincl, which is what I think was

2004-07-18T04:09:40+00:00

intended.  This fixes the build, but might require revision.

Add a kern_setsockopt and kern_getsockopt which can read the option

2004-07-17T21:06:36+00:00

values from either user land or from the kernel. Use them for
[gs]etsockopt and to clean up some calls to [gs]etsockopt in the
Linux emulation code that uses the stackgap.

Clean up and wash struct iovec and struct uio handling.

2004-07-10T15:42:16+00:00

Add copyiniov() which copies a struct iovec array in from userland into
a malloc'ed struct iovec.  Caller frees.

Change uiofromiov() to malloc the uio (caller frees) and name it
copyinuio() which is more appropriate.

Add cloneuio() which returns a malloc'ed copy.  Caller frees.

Use them throughout.

Use a couple of regular kernel entry points, rather than COMPAT_43

2004-07-08T10:18:07+00:00

entry points.

Quick fix for LINT breakage caused by interface changes in accept(2), etc.

2003-12-25T09:59:02+00:00

The log message for rev.1.160 of kern/uipc_syscalls.c and associated
changes only claimed to add restrict qualifiers (which have no effect in
the kernel so they probably shouldn't be added), but the following
interface changes were also made:
- caddr_t to `void *' and `struct sockaddr_t *'
- `int *' to `socklen_t *'.
These interface changes are not quite null, and this fix is quick (like
the changes in uipc_syscalls 1.160) because it uses bogus casts instead
of complete bounds-checked conversions.

Things should be fixed better when the conversions can be done without
using the stack gap.  linux_check_hdrincl() already uses the stack gap
and is fixed completely though the type mismatches in it were not fatal
(there were only fatal type mismatches from unopaquing pointers to
[o]sockaddr't's -- the difference between accept()'s args and oaccept()'s
args is now non-opaque, but this is not reflected in their args structs).
