This commit was manufactured to restore the state of the 6.0-RELEASE image.

o Split out kernel part of execve(2) syscall into two parts: one that

2005-01-29T23:12:00+00:00

  copies arguments into the kernel space and one that operates
  completely in the kernel space;

o use kernel-only version of execve(2) to kill another stackgap in
  linuxlator/i386.

Do a pass over all modules in the kernel and make them return EOPNOTSUPP

for unknown events.

A number of modules return EINVAL in this instance, and I have left
those alone for now and instead taught MOD_QUIESCE to accept this
as "didn't do anything".

Add an additional field to the elf brandinfo structure to support

quicker exec-time replacement of the elf interpreter on an emulation
environment where an entire /compat/* tree isn't really warranted.

Add sysentvec->sv_fixlimits() hook so that we can catch cases on 64 bit

2003-09-25T01:10:26+00:00

systems where the data/stack/etc limits are too big for a 32 bit process.

Move the 5 or so identical instances of ELF_RTLD_ADDR() into imgact_elf.c.

Supply an ia32_fixlimits function.  Export the clip/default values to
sysctl under the compat.ia32 heirarchy.

Have mmap(0, ...) respect the current p->p_limits[RLIMIT_DATA].rlim_max
value rather than the sysctl tweakable variable.  This allows mmap to
place mappings at sensible locations when limits have been reduced.

Have the imgact_elf.c ld-elf.so.1 placement algorithm use the same
method as mmap(0, ...) now does.

Note that we cannot remove all references to the sysctl tweakable
maxdsiz etc variables because /etc/login.conf specifies a datasize
of 'unlimited'.  And that causes exec etc to fail since it can no
longer find space to mmap things.

Rename P_THREADED to P_SA. P_SA means a process is using scheduler

Use __FBSDID().

Sync up linux and svr compat elf fixup functions for exec(). These

2003-03-21T19:49:34+00:00

functions are now all basically identical except that alpha linux uses
Elf64 arguments and svr4 and i386 linux use Elf32.  The fixups include
changing the first argument to be a register_t ** to match the prototype
for fixup functions, asserting that the process in the image_params struct
is always curproc and removing unnecessary locking to read credentials as a
result, and a few style fixes.
