cc7532aaf0 Add a sysctl variable which can help stop chroot(2) escapes.
kern.chroot_allow_open_directories = 0
	chroot(2) fails if there are open directories.

kern.chroot_allow_open_directories = 1 (default)
	chroot(2) fails if there are open directories and the process
	is subject of a previous chroot(2).

kern.chroot_allow_open_directories = anything else
	filedescriptors are not checked.  (old behaviour).

I'm very interested in reports about software which breaks when
running with the default setting.

07799a2af1 Backed out most of rev.1.4. I didn't submit it; I only submitted a
request for it something like it.  It was poorly worded and too
far from both POSIX wording and normal (mal)practice by referring to
sysconf(_SC_NGROUPS_MAX) instead of {NGROUPS_MAX} or NGROUPS.  POSIX.1
uses curly braces to mark up "symbolic constants or limits [that may
be] defined in certain headers".  Since we don't document this markup,
don't use it.  Just use NGROUPS_MAX.

abd022381d Changed the type of quotactl()'s 4th arg from char *' to void *'
so that non-sloppy applications can call it without using disgusting
casts to avoid warnings.  The 4th arg is sort of varargs -- it must
sometimes represent a filename, sometimes a struct pointer, and is
sometimes unused.  The arg type is still caddr_t in the kernel.

2907af2a96 Mostly remove the VM_STACK OPTION.
This changes the definitions of a few items so that structures are the
same whether or not the option itself is enabled. This allows
people to enable and disable the option without recompilng the world.

As the author says:

|I ran into a problem pulling out the VM_STACK option.  I was aware of this
|when I first did the work, but then forgot about it.  The VM_STACK stuff
|has some code changes in the i386 branch.  There need to be corresponding
|changes in the alpha branch before it can come out completely.

what is done:
|
|1) Pull the VM_STACK option out of the header files it appears in.  This
|really shouldn't affect anything that executes with or without the rest
|of the VM_STACK patches.  The vm_map_entry will then always have one
|extra element (avail_ssize).  It just won't be used if the VM_STACK
|option is not turned on.
|
|I've also pulled the option out of vm_map.c.  This shouldn't harm anything,
|since the routines that are enabled as a result are not called unless
|the VM_STACK option is enabled elsewhere.
|
|2) Add what appears to be appropriate code the the alpha branch, still
|protected behind the VM_STACK switch.  I don't have an alpha machine,
|so we would need to get some testers with alpha machines to try it out.
|
|Once there is some testing, we can consider making the change permanent
|for both i386 and alpha.
|
[..]
|
|Once the alpha code is adequately tested, we can pull VM_STACK out
|everywhere.

cf6229a854 Build __error.c into libc, but not libc_r. The weak symbol in the
file works with libpthread, but when built into libc_r which has a non-weak
symbol of the same name, the linker behaves unpredicatably and sometimes
links the wrong symbol. The linker behaviour is a byproduct of what
the program calls from object to object so it is like winning a lottery
if the program actually works. The odds are quite good - 95:1, I think.
We need a sure thing, though, so weak symbols can't be used instead
of renaming things.

abd529ceba Yikes, this is the worst of the lot. Bruce suggested doing this (!).
Include the architecture specific sys makefile like previously, but
what this contains differs. It defines MDASM which list architecture
specific asm code that *replaces* syscalls of the same name defined
in MIASM (which gets defined by the syscall.mk or netbsd_syscall.mk
dependent of NETBSD_SYSCALLS being defined). If a syscall has a
C source implementation or something funny done to it, or just doesn't
need default asm source generated for it, then it is listed in NOASM.

syscall.mk is generated by makesyscalls.sh with other syscall files.
netbsd_syscall.mk is a hand-generated equivalent. So if a new syscall
is added and no other makefiles are edited, it will automatically have
the default asm source generated for it (whether you want it or not).

Anything listed in MDASM gets added to SRCS and gets built. For
each syscall name in MIASM, if it doesn't exist in MDASM or NOASM,
it gets added to the ASM or ASMR lists to have code generated for it.
If the syscall name was listed in HIDDEN_SYSCALLS (intended for use
by libc_r, not libc which has it defined, but empty), then the name
is added to the ASMR list and gets renamed before being built;
otherwise it is added to the ASM list and gets built with the same
name.

I wonder if this is too complicated. But it works on both i386 and alpha.

hopefully this makes it difficult enough for people to
do this accidentally.
see the new chmod(2) man page for detailed info.

Ever since I first say the way the mount flags were used I've hated the
fact that modes, and events, internal and exported, and short-term
and long term flags are all thrown together. Finally it's annoyed me enough..
This patch to the entire FreeBSD tree adds a second mount flag word
to the mount struct. it is not exported to userspace. I have moved
some of the non exported flags over to this word. this means that we now
have 8 free bits in the mount flags. There are another two that might
well move over, but which I'm not sure about.
The only user visible change would have been in pstat -v, except
that davidg has disabled it anyhow.
I'd still like to move the state flags and the 'command' flags
apart from each other.. e.g. MNT_FORCE really doesn't have the
same semantics as MNT_RDONLY, but that's left  for another day.
