- Correct size and position variables type from long to size_t.
- Do not set errno to ENOMEM on malloc failure, as malloc already does so.
- Implement the concept of "buffer data length", which mandates what SEEK_END
refers to and the allowed extent for a read.
- Use NULL as read-callback if the buffer is opened in write-only mode.
Conversely, use NULL as write-callback when opened in read-only mode.
- Implement the handling of the ``b'' character in the mode argument. A binary
buffer differs from a text buffer (default mode if ``b'' is omitted) in that
NULL bytes are never appended to writes and that the "buffer data length"
equals to the size of the buffer.
- Remove shall from the man page. Use indicative instead. Also, specify that
the ``b'' flag does not conform with POSIX but is supported by glibc.
- Update the regression test so that the ``b'' functionality and the "buffer
data length" concepts are tested.
- Minor style(9) corrections.

Since ARP and routing are separated, "proxy only" entries
don't have any meaning, thus we don't need additional field
in sockaddr to pass SIN_PROXY flag.
New kernel is binary compatible with old tools, since sizes
of sockaddr_inarp and sockaddr_in match, and sa_family are
filled with same value.
The structure declaration is left for compatibility with
third party software, but in tree code no longer use it.

Right now, ic_curchan seems to be updated rather quickly (ie, during
the ioctl) and before the driver gets notified of what's going on.
So what I was seeing was:
* NIC was in channel X;
* It generates PHY errors for channel X;
* an ioctl comes along from userland and changes things to channel Y;
* .. this updates ic_curchan, but hasn't yet reset the hardware;
* in parallel, RX is occuring and it looks at ic_curchan;
* .. which is channel Y, so events get stamped with that now.
Sigh.
heavily used when parsing config files. Mostly these changes avoid making
temporary copies of the strings, and avoid doing byte at a time append
operations, on the most-used code path.
On a 1.2 GHz ARM processor this reduces the time to parse the config files
from 13 to 6 seconds.

into the FreeBSD boot loader, typically for non-USB aware BIOSes, EFI systems
or embedded platforms. This is also useful for out of the system compilation
of the FreeBSD USB stack for various purposes. The USB kernel files can
now optionally include a global header file which should include all needed
definitions required to compile the FreeBSD USB stack. When the global USB
header file is included, no other USB header files will be included by
default.
Add new file containing the USB stack configuration for the
FreeBSD loader build.
Replace some __FBSDID()'s by /* $FreeBSD$ */ comments. Now all
USB files follow the same style.
Use cases:
- console in loader via USB
- loading kernel via USB

their socket connection any time, and devd only notices that when it gets an
error trying to write an event to the client. On a system with no device
change activity, clients could connect and disappear repeatedly without devd
noticing, leading to an ever-growing list of open socket descriptors in devd.
Now devd uses poll(2) looking for POLLHUP on all existing clients every time
a new client connection is established, and also periodically (once a minute)
to proactively find zombie clients and reap the socket descriptors. It also
now has a connection limit, configurable with a new -l <num> command line arg.
When the maximum number of connections is reached it stops accepting new
connections until some current clients drop off.

gettimeofday(2) and related functions in the default configuration.
The motivation for the TSC-low timecounter, as described in the
r222866, seems to provide a workaround for the non-serializing
behaviour of the RDTSC on some Intel hardware. Tests demonstrate that
even with the pre-shift of 8, the cross-core non-monotonicity of the
RDTSC is still observed reliably, e.g. on the Nehalems. The r238755
and r238973 implemented the proper fix for the issue.
The pre-shift of 1 is applied to keep TSC not overflowing for the
frequency of hardclock down to 2 sec/intr. The pre-shift is made a
tunable to allow the easy debugging of the issues users could see with
the shift being too low.
