Catch a set vnet upon return to user space. This usually
means return paths with CURVNET_RESTORE() missing.
If VNET_DEBUG is turned on we can even tell the function
that did the CURVNET_SET() which is really helpful; else
we print "N/A".

While updating Tx stats, already freed node could be referred and cause
page fault. To avoid such panic, spool Tx stats in driver's softc. Then,
on every ratectl interval, grab node though ieee80211_iterate_nodes() and
update ratectl stats.

The algorithm is supposed to work as follows:
in order to prevent starvation, when a new client starts being served we
record the start time and reset the counter of bytes served.
We then switch to a new client after a certain amount of time or bytes,
even if the current one still has pending requests.
To avoid charging a new client the time of the first seek,
we start counting time when the first request is served.
Unfortunately a bug in the previous version of the code failed
to set the start time in certain cases, resulting in some processes
exceeding their timeslice.
The fix (in this patch) is trivial, though it took a while to find
out and replicate the bug.
Thanks to Tommaso Caprai for investigating and fixing the problem.

socket/bind/send(data)/close. If the timing was right
we would dereference a socket that is NULL.

object's size field. Previously, that field was always zero, even
when the object tn_reg.tn_aobj contained numerous pages.
Apply style fixes to tmpfs_reg_resize().

cause OpenSSL to parse past the end of the message.
Note: Applications are only affected if they act as a server and call
SSL_CTX_set_tlsext_status_cb on the server's SSL_CTX. This includes
Apache httpd >= 2.3.3, if configured with "SSLUseStapling On".

Security: CVE-2011-0014
Obtained from: OpenSSL CVS
Due to UFS insistence to pretend that device sector size is 512 bytes,
sector size is obtained from ioctl(DIOCGSECTORSIZE) for real devices,
and from the label otherwise. The file images without label have to
be made with 512 sector size.
