78b73f3e05 Fix some security bugs in the SVR4 emulator:
- Return NULL instead of returning memory outside of the stackgap
  in stackgap_alloc() (FreeBSD-SA-00:42.linux)
- Check for stackgap_alloc() returning NULL in svr4_emul_find(),
  and clean_pipe().
- Avoid integer overflow on large nfds argument in svr4_sys_poll()
- Reject negative nbytes argument in svr4_sys_getdents()
- Don't copy out past the end of the struct componentname
  pathname buffer in svr4_sys_resolvepath()
- Reject out-of-range signal numbers in svr4_sys_sigaction(),
  svr4_sys_signal(), and svr4_sys_kill().
- Don't malloc() user-specified lengths in show_ioc() and
  show_strbuf(), place arbitrary limits instead.
- Range-check lengths in si_listen(), ti_getinfo(), ti_bind(),
  svr4_do_putmsg(), svr4_do_getmsg(), svr4_stream_ti_ioctl().

Some fixes obtain from OpenBSD.

7e8766a940 When a driver successfully created a device on demand, we can directly
pick up the DEVFS inode number from the dev_t and find our directory
entry from that, we don't need to scan the directory to find it.

This also solves an issue with on-demand devices in subdirectories.

9027d603d3 - Synchronize access to a vm page's valid field using the containing
vm object's lock.

bab1f05277 Put the RSE backing store at a fixed address. This change is triggered
by libguile that needs to know the base of the RSE backing store. We
currently do not export the fixed address to userland by means of a
sysctl so user code needs to hardcode it for now. This will be revisited
later.

The RSE backing store is now at the bottom of region 4. The memory stack
is at the top of region 4. This means that the whole region is usable
for the stacks, giving a 61-bit stack space.

Port: lang/guile (depended of x11/gnome2)

a10c0e4574 Fix a problem where m_defrag would allocate a new mbuf to replace the
chain passed into dc_encap, which dc_start was unaware of.  This caused
the old (now invalid) mbuf to be passed to BPF_MTAP.

5d5b5d0f99 Add a new macro M_ASSERTVALID which ensures that the mbuf in question
is non-free.  (More checks can/should be added in the future.)

Use M_ASSERTVALID in BPF_MTAP so that we catch when freed mbufs are
passed in, even if no bpf listeners are active.

Inspired by a bug in if_dc caught by Kenjiro Cho.

0513e13e31 Add a testcase which validates that the same buffer can be passed to
rijndael_blockDecrypt() as both input and output.

This property is important because inside rijndael we can get away
with allocating just a 16 byte "work" buffer on the stack (which
is very cheap), whereas the calling code would need to allocate the
full sized buffer, and in all likelyhood would have to do so with
an expensive malloc(9).

d6ad008082 Change the default mode for lost+found from 01777 to 0700. The
original intention of the less restrictive permissions was to allow
users to move or delete recovered files that they own. However, it
is better to not create world-writable directories by default; the
administrator can always pre-create lost+found if different permissions
are desired.

e1419c08e2 falloc allocates a file structure and adds it to the file descriptor
table, acquiring the necessary locks as it works. It usually returns
two references to the new descriptor: one in the descriptor table
and one via a pointer argument.

As falloc releases the FILEDESC lock before returning, there is a
potential for a process to close the reference in the file descriptor
table before falloc's caller gets to use the file. I don't think this
can happen in practice at the moment, because Giant indirectly protects
closes.

To stop the file being completly closed in this situation, this change
makes falloc set the refcount to two when both references are returned.
This makes life easier for several of falloc's callers, because the
first thing they previously did was grab an extra reference on the
file.
