When item forwarded refence counter is incremented, when item
processed, counter decremented. When counter reaches zero,
apply handler is getting called.
Now it allows to report right connect() call status from user-level
at the right time.
This is much simpler than for ffs since there are many fewer places
where we need to choose between a delayed write and a sync write --
just 5 in msdosfs and more than 30 in ffs.
This is more complete and correct than in ffs. Several places in ffs
are are still missing the choice. ffs_update() has a layering violation
that breaks callers which want to force a sync update (mainly fsync(2)
and O_SYNC write(2)).
However, fsync(2) and O_SYNC write(2) are still more broken than in
ffs, since they are broken for default (non-sync non-async) mounts
too. Both fail to sync the FAT in all cases, and both fail to sync
the directory entry in some cases after losing a race. Async everything
is probably safer than the half-baked sync of metadata given by default
mounts.
us to scale up to sb_max, aka kern.ipc.maxsockbuf.
We do this because there are broken firewalls that will corrupt the window
scale option, leading to the other endpoint believing that our advertised
window is unscaled. At scale factors larger than 5 the unscaled window will
drop below 1500 bytes, leading to serious problems when traversing these
broken firewalls.
With the default maxsockbuf of 256K, a scale factor of 3 will be chosen by
this algorithm. Those who choose a larger maxsockbuf should watch out
for the compatiblity problems mentioned above.

queue so the output network card must support the same tagging mechanism as
how the frame was input (prepended Ethernet header tag or stripped HW mflag).
Now the vlan Ethernet header is _always_ stripped in ether_input and the mbuf
flagged, only only network cards with VLAN_HWTAGGING enabled would properly
re-tag any outgoing vlan frames.
If the outgoing interface does not support hardware tagging then readd the vlan
header to the front of the frame. Move the common vlan encapsulation in to
ether_vlanencap().

From the OpenSSL advisory:
Andy Polyakov discovered a flaw in OpenSSL's DTLS
implementation which could lead to the compromise of clients
and servers with DTLS enabled.
DTLS is a datagram variant of TLS specified in RFC 4347 first
supported in OpenSSL version 0.9.8. Note that the
vulnerabilities do not affect SSL and TLS so only clients and
servers explicitly using DTLS are affected.
We believe this flaw will permit remote code execution.

leaving space for adding missing options. Negative options are sorted
after removing their "no" prefix, and generic options are sorted before
msdosfs-specific ones.
At least one port (net-mgmt/net-snmp) creates man-pages which are
in the format:
.SH NAME
The Net-SNMP agent \- The snmp agent responds to SNMP queries from management stations.
.PP
.SS "Modules"
At this moment, makewhatis determines the end of the .SH NAME section
as where it finds .SH again, but there is none here, is it "terminated"
by the .SS.

(except indirectly for the size pseudo-attribute). If anything deserves
a sync update, then it is ids and immutable flags, since these are
related to security, but ffs never synced these and msdosfs doesn't
support them. (ufs_setattr() only does an update in one case where
it is least needed (for timestamps); it did pessimal sync updates for
timestamps until 1998/03/08 but was changed for unlogged reasons related
to soft updates.)
Now msdosfs calls deupdat() with waitfor == 0, which normally gives a
delayed update to disk but always gives a sync update of timestamps
in core, while for ffs everything is delayed until the syncer daemon
or other activity causes an update (except for timestamps).
This gives a large optimization mainly for things like cp -p, where
attribute adjustment could easily triple the number of physical I/O's
if it is done synchronously (but cp -p to msdosfs is not as bad as
that, since msdosfs doesn't support many attributes so null adjustments
are more common, and msdosfs doesn't support ctimes so even if cp
doesn't weed out null adjustments they don't become non-null after
clobbering the ctime).
- Check for duplicated symbols and suggest moving them to ObsoleteVersions.
- Improve and unify error handling.
- Make the regular expressions more uniform, robust, and less sensitive
to harmless variations in the input such as those to whitespace amount.
