no device at <attachment>
<attachment> can take two forms: either numbered/wildcarded, in which
case only exactly matching instances will be removed, or plain (with
no number or wildcard), in which case all matching instances will be
removed.
When <attachment> is a plain interface attribute, all instances using
that attribute (either directly or through an explicit device) will be
removed.
E.g.:
auich* at pci? dev ? function ?
audio0 at audiobus?
audio1 at auich?
audio* at auich0
no device at auich0 -> removes audio*
no device at auich? -> removes audio1
no device at auich -> removes audio1 _and_ audio*
no device at audiobus? -> removes audio0
no device at audiobus -> removes audio0, audio1 and audio*
no <device>
As in the previous case, <device> can either be numbered/starred, in
which case all exactly matching instances are removed, or plain, in
which case all instances of the device are removed.
E.g.: (continuing previous example)
no audio* -> removes 'audio* at auich0'
no audio -> removes all audio instances
track of instances attaching at root, and walk down the tree of active
device instances. Then, all instances that are not marked active are
found as orphans.
Doing it that way allows us to simply ignore orphan devices, instead of
warning about them and still keep them in the configuration. Now, orphaned
instances are considered as never having existed.
In the end, this allows 'no <device> at <attachment>' to be much more
efficient, as the user doesn't have to negate all descendents of the
instance s/he actually wants to negate. Warnings are still emitted,
though.
While there, make official a side-effect of the previous lack of action
against orphaned instances: config(1) used to warn about instances that
attach at a numbered device when no instance of that device with that
number existed, even though there was a starred instance of the device.
E.g. (provided by Alan Barrett):
pciide* at pci? dev ? function ? flags 0x0000
wdc0 at isa? port 0x1f0 irq 14 flags 0x00
wdc1 at isa? port 0x170 irq 15 flags 0x00
atabus* at ata?
wd0 at atabus0 drive 0
With this commit, config(1) will no longer warn about 'wd0 at atabus0'.
- Use realloc instead of allocating 1000 structures.
- Remove NUSERS nonsense. If this is kept, shouldn't
who(1) comply with it too?
- Be consistent with who(1). Add two identical options
from who(1). These are -q and -H.
- General Cleans:
- Move globals into local scope
- Re-write a macro to remove an uneccessary
variable.
- Use UT_NAMESIZE.
- Remove unecessary header etc.

was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.
The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.
Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.

. we now handle ^C correctly in all cases

. \ can be used to escape any (special) character in file names
character instead of using the IS_ESCAPE() macro which tests for ^V because the
former is mandated by the standards, and the latter is insane.
This is a very small part in addressing PR bin/26046 by lukem@.
Before, in order to escape a special character, you had to use a literal ^V,
which is type ^V twice before the character; whereas now, you use \.
Because the fix will remain partial for a while, you have to remove \ from
your shellmeta option otherwise the \ is swallowed by the invoked shell that
handles arguments expansion.
Please complain if you want ^V^V to also work, but please don't call me a
heretic.
of ignoring alphanumerical and blank characters from the shellmeta option.
The former code was using a character pointed to by a pointer as a boolean
to check whether to enable this functionality, but in the meantime the pointer
was used for something else. Introduce a variable for this boolean so that
the functionality actually works.
of text-recording input (usually text in insert mode) from the other cases
(e.g. ex command input). If recording, morph to escape key so that the input
is correctly finished for a potential replay; if not, simply bail out and
notify that something wrong occurs. Callers will cope.
The previous fix could make ^C sometimes produce a file completion
or a command edition, depending on the settings of the user.
I think this is the correct fix for since closed PR bin/11544 by pooka@. ;-)

net.bpf.stats and net.bpf.peers sysctls respectively. netstat(1) now
has an additional syntax:
netstat [-s] [-B] [-I Interface]
Only the super user can see a list of BPF peers with the following command:
# netstat -B
Active BPF peers
PID Int Recv Drop Capt Flags Bufsize Comm
4941 lo0 0 0 0 I--S- 262144 tcpdump
252 ex0 19668 0 5 I-RS- 32768 dhclient
And every user can see the BPF statistics with:
$ netstat -s -B
bpf:
19669 total packets received
5 total packets captured
0 total packets dropped
This idea came from FreeBSD (Christian S.J. Peron) but, currently, they
doen't have a userland utility in the base system to read the sysctls.
