f3cd77cf07 Add a placeholder for the execve_mac() system call, similar to SELinux's
execve_secure() system call, which permits a process to pass in a label
for a label change during exec.  This permits SELinux to change the
label for the resulting exec without a race following a manual label
change on the process.  Because this interface uses our general purpose
MAC label abstraction, we call it execve_mac(), and wrap our port of
SELinux's execve_secure() around it with appropriate sid mappings.

2a53e50eeb Update the unwind information when modules are loaded and unloaded
by using the linker hooks. Since these hooks are called for the
kernel as well, we don't need to deal with that with a special
SYSINIT. The initialization implicitly performed on the first
update of the unwind information is made explicit with a SYSINIT.
We now don't need the _ia64_unwind_{start|end} symbols.

d35d608c07 Add two hooks to signal module load and module unload to MD code.
The primary reason for this is to allow MD code to process machine
specific attributes, segments or sections in the ELF file and
update machine specific state accordingly. An immediate use of this
is in the ia64 port where unwind information is updated to allow
debugging and tracing in/across modules. Note that this commit
does not add the functionality to the ia64 port. See revision 1.9
of ia64/ia64/elf_machdep.c.

b98187d339 Permits UFS ACLs to be used with the GENERIC kernel. Due to recent
ACL configuration changes, this shouldn't result in different code paths
for file systems not explicitly configured for ACLs by the system
administrator.  For UFS1, administrators must still recompile their
kernel to add support for extended attributes; for UFS2, it's sufficient
to enable ACLs using tunefs or at mount-time (tunefs preferred for
reliability reasons).  UFS2, for a variety of reasons, including
performance and reliability, is the preferred file system for use with
ACLs.

e92a317846 Fix kernel module loading on ia64. Cross-module function calls
were improperly relocated due to faulty logic in lookup_fdesc()
in elf_machdep.c. The symbol index (symidx) was bogusly used for
load modules other than the one the relocation applied to. This
resulted in bogus bindings and consequently runtime failures.

The fix is to use the symbol index only for the module being
relocated and to use the symbol name for look-ups in the
modules in the dependent list. As such, we need a function to
return the symbol name given the linker file and symbol index.

f02cbfb108 Plug two holes where we returned to userland without restoring
the predicate registers. Even though the ITLB and DTLB interrupts
happen often enough, this bug didn't do much harm. The reason
is that the interrupt handlers only modify p1 and since this is
a preserved (callee-saved) register it is hardly used in code
generated by the compiler. Compilers use scratch registers by
default. Changing the interrupt handlers to use p6 (ie a scratch
register) proved that the bug was in fact fatal.

951c3e53b2 NB: This commit does *NOT* make GEOM the default in FreeBSD
NB: But it will enable it in all kernels not having options "NO_GEOM"

Put the GEOM related options into the intended order.

Add "options NO_GEOM" to all kernel configs apart from NOTES.

In some order of controlled fashion, the NO_GEOM options will be
removed, architecture by architecture in the coming days.

There are currently three known issues which may force people to
need the NO_GEOM option:

boot0cfg/fdisk:
        Tries to update the MBR while it is being used to control
        slices.  GEOM does not allow this as a direct operation.

SCSI floppy drives:
        Appearantly the scsi-da driver return "EBUSY" if no media
        is inserted.  This is wrong, it should return ENXIO.

PC98:
        It is unclear if GEOM correctly recognizes all variants of
        PC98 disklabels.  (Help Wanted!  I have neither docs nor HW)

These issues are all being worked.

8fd35a03b5 Do a bit of rude hackery to get clock interrupts on all CPUs. This
is partly based on the Alpha system which duplicates the clock to
each cpu, instead of doing a clock roundrobin like on i386.  This means
we get hz * ncpu clocks per second and so we have to seperate clock
sampling from actual 'do the work' clock processing.  The BSP runs the
complete processing, the rest just sample state etc.

Using the on-cpu interval timer is not ideal as it will drift.  There
is more to be done here, we should use an external clock source.

57a346a213 (This commit touches about 15 disk device drivers in a very consistent
and predictable way, and I apologize if I have gotten it wrong anywhere,
getting prior review on a patch like this is not feasible, considering
the number of people involved and hardware availability etc.)

If struct disklabel is the messenger: kill the messenger.

Inside struct disk we had a struct disklabel which disk drivers used to
communicate certain metrics to the disklayer above (GEOM or the disk
mini-layer).  This commit changes this communication to use four
explicit fields instead.

Amongst the benefits is that the fields do not get overwritten by
wrong or bogus on-disk disklabels.

Once that is clear, <sys/disk.h> which is included in the drivers
no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in,
the few places that needs them, have gotten explicit #includes for
them.

The disklabel inside struct disk is now only for internal use in
the disk mini-layer, so instead of embedding it, we malloc it as
we need it.

This concludes (modulus any mistakes) the series of disklabel related
commits.

I belive it all amounts to a NOP for all the rest of you :-)

d376fc4110 For reasons now lost in historical fog, the bounds_check_with_label()
function were put in i386/i386/machdep.c from where it has been
cut and pasted to other architectures with only minor corruption.

Disklabel is really a MI format in many ways, at least it certainly
is when you operate on struct disklabel.

Put bounds_check_with_label() back in subr_disklabel.c where it belongs.

03dc7bc4a4 Implement db_print_backtrace() if DDB is compiled into the kernel. This
MD function is just a wrapper around db_stack_trace_cmd() that prints out
a backtrace of curthread.  Currently, this function is only implemented
on i386 and alpha (and the alpha version isn't quite tested yet, will do
that in a bit).  Other changes:

- For i386, fix a bug in the raw frame address case.  The eip we extract
  from the passed in frame address does not match the frame we received.
  Thus, instead of printing a bogus frame with the wrong eip, go ahead
  and advance frame down to the same frame as the eip we are using.
- For alpha, attempt to add a way of doing a raw trace for alpha.  Instead
  of passing a frame address in 'addr', pass in a pointer to a structure
  containing PC and KSP and use those to start the backtrace.  The alpha
  db_print_backtrace() uses asm to read in the current PC and KSP values
  into such a request.

This part of sendsig could be slightly refactored to use an MI interface, or
ideally, *sendsig*() would have an API change to accept a siginfo_t, which
would be filled out by an MI function in the level above sendsig, and said MI
function would make a small call into MD code to fill out the MD parts (some
of which may be bogus, such as the si_addr stuff in some places).  This would
eventually make it possible for parts of the kernel sending signals to set up
a siginfo with meaningful information.

Change Maxmem and physmem and related variables to 'long', mostly for

While moving them, make a few adjustments (submitted by bde):
o __ct_rune_t needs to be precisely `int', not necessarily __int32_t,
  since the arg type of the ctype functions is int.
o __rune_t, __wchar_t and __wint_t inherit this via a typedef of

44404e4547 In order to better support flexible and extensible access control,
make a series of modifications to the credential arguments relating
to file read and write operations to cliarfy which credential is
used for what:

- Change fo_read() and fo_write() to accept "active_cred" instead of
  "cred", and change the semantics of consumers of fo_read() and
  fo_write() to pass the active credential of the thread requesting
  an operation rather than the cached file cred.  The cached file
  cred is still available in fo_read() and fo_write() consumers
  via fp->f_cred.  These changes largely in sys_generic.c.

For each implementation of fo_read() and fo_write(), update cred
usage to reflect this change and maintain current semantics:

- badfo_readwrite() unchanged
- kqueue_read/write() unchanged
  pipe_read/write() now authorize MAC using active_cred rather
  than td->td_ucred
- soo_read/write() unchanged
- vn_read/write() now authorize MAC using active_cred but
  VOP_READ/WRITE() with fp->f_cred

Modify vn_rdwr() to accept two credential arguments instead of a
single credential: active_cred and file_cred.  Use active_cred
for MAC authorization, and select a credential for use in
VOP_READ/WRITE() based on whether file_cred is NULL or not.  If
file_cred is provided, authorize the VOP using that cred,
otherwise the active credential, matching current semantics.

Modify current vn_rdwr() consumers to pass a file_cred if used
in the context of a struct file, and to always pass active_cred.
When vn_rdwr() is used without a file_cred, pass NOCRED.

These changes should maintain current semantics for read/write,
but avoid a redundant passing of fp->f_cred, as well as making
it more clear what the origin of each credential is in file
descriptor read/write operations.

Follow-up commits will make similar changes to other file descriptor
operations, and modify the MAC framework to pass both credentials
to MAC policy modules so they can implement either semantic for
revocation.

  (1) Defining macros in <machine/ansi.h> gets in the way of that

cc7b2e4248 Infrastructure tweaks to allow having both an Elf32 and an Elf64 executable
handler in the kernel at the same time.  Also, allow for the
exec_new_vmspace() code to build a different sized vmspace depending on
the executable environment.  This is a big help for execing i386 binaries
on ia64.   The ELF exec code grows the ability to map partial pages when
there is a page size difference, eg: emulating 4K pages on 8K or 16K
hardware pages.

Flesh out the i386 emulation support for ia64.  At this point, the only
binary that I know of that fails is cvsup, because the cvsup runtime
tries to execute code in pages not marked executable.

The machine that I have has 4 cpus and a very big hole in the middle.
This makes the bogus '(last_address - first_address) / PAGE_SIZE'

62e40d1277 Add a special page zero entry point intended to be called via the single
threaded VM pagezero kthread outside of Giant.  For some platforms, this
is really easy since it can just use the direct mapped region.  For others,
IPI sending is involved or there are other issues, so grab Giant when
needed.

We still have preemption issues to deal with, but Alan Cox has an
interesting suggestion on how to minimize the problem on x86.

Use Luigi's hack for preserving the (lack of) priority.

Turn the idle zeroing back on since it can now actually do something useful
outside of Giant in many cases.

While here, use the UMA zone hooks to keep a cache of preinitialized
proc structures handy, just like the thread system does.  This eliminates
one dependency on 'struct proc' being persistent even after being freed.
There are some comments about things that can be factored out into

go back to the old lazy mechanism.  Note that if UMA destroys pages that
used to contain proc structures, we'll lose the corresponding upage
forever.  (zones never did this - once a page was allocated, it stayed
attached to the proc zone forever)
