gehenna 77a6b82b27 Merge the gehenna-devsw branch into the trunk.
This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

thorpej 011d4d5f44 Add kernel support for having userland provide the signal trampoline:
* struct sigacts gets a new sigact_sigdesc structure, which has the
  sigaction and the trampoline/version.  Version 0 means "legacy kernel
  provided trampoline".  Other versions are coordinated with machine-
  dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
  the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
  trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions.  Instead,
  sendsig() looks up the handler by peeking in the sigacts for the
  process getting the signal (since it has to look in there for the
  trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
  its arguments based on the trampoline version in the sigacts.

Changes to libc to use the new facility will be checked in later.  Kernel
version not bumped; we will ride the 1.6C bump made recently.

christos 381e6a7764 make the stackgap_{init,alloc} functions MP friendly (i.e. pass struct proc *
in, instead of using curproc). While there add an optional size argument to
stackgap_init.

mrg af640de164 move the COMPAT_SUNOS SO_BROADCAST hack out of uipc_socket.c into the
compat/sunos code.  besides being cleaner this allows the sunos LKM
to properly work without any special kernel hacks.

tsutsui 1011f9fbcc Don't define COMPAT_SUNOS here. It is defined in opt_compat_sunos.h
and <sys/ioctl.h> and <sys/tty.h> include it properly.

XXX Is this needed for LKM?

thorpej 80cc38a1af Fix a partial construction problem that can cause race conditions
between creation of a file descriptor and close(2) when using kernel
assisted threads.  What we do is stick descriptors in the table, but
mark them as "larval".  This causes essentially everything to treat
it as a non-existent descriptor, except for fdalloc(), which sees a
filled slot so that it won't (incorrectly) allocate it again.  When
a descriptor is fully constructed, the code that has constructed it
marks it as "mature" (which actually clears the "larval" flag), and
things continue to work as normal.

While here, gather all the code that gets a descriptor from the table
into a fd_getfile() function, and call it, rather than having the
same (sometimes incorrect) code copied all over the place.

after sunos.h change (cast is safe; a SunOS binary will pas a 32 bit
pointer).

jdolecek 01040d97a2 add e_path (emulation path) to struct emul, which replaces emulation-specific
*_emul_path variables

change macros CHECK_ALT_{CREAT|EXIST} to use that, 'root' doesn't need
to be passed explicitly any more and *_CHECK_ALT_{CREAT|EXIST} are removed
change explicit emul_find() calls in probe functions to get the emulation
path from the checked exec switch entry's emulation

remove no longer needed header files

add e_flags and e_syscall to struct emul; these are unsed and empty for now

osrelease, and ostype and remove "extern char foo[];" (for hostname
and domainname too).

Also delete redunctant decl of boottime in kern_info_43.c.

kleink 230876cf26 Merge parts of chs-ubc2 into the trunk:
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.

thorpej e3669c3393 Add "use counting" to file entries. When closing a file, and it's reference
count is 0, wait for use count to drain before finishing the close.

This is necessary in order for multiple processes to safely share file
descriptor tables.

rvb 26b955eec7 ufs_readdir no longer checks if vp->v_type != VDIR so
the individual emulated readdirs must check.
Since netbsd and freebsd return EINVAL for the error
and I don't know what the other platforms do, return
EINVAL for them too.

bouyer 1cd83a5971 Fix "missing entries" bug when reading large directories: When reading a
directory and running out of space in the dest buffer, off should point to the
current entry (which was not saved) and not to the next.
I discovered this bug using linux and SunOS emulation over NFS, but seems to
affect other emulations as well.

also take a char *.
