This will manage pmc functionality with a more
manageable structure of subcommands rather than the
gradually accreted spaghetti logic of overlapping flags
that exists in pmcstat.
This is intended to ultimately have all the same functionality
as pmcannotate+pmccontrol+pmcstat. Currently it just has
"stat" and "system-stat" - counters for the process itself and counters
for the system as a whole respectively (i.e. system-stat includes kernel
threads). Note that the rusage results (page faults/context switches/
user/sys) for stat-system will not account for the system as a whole -
only for the child process specified on the command line.
Implementing stat was suggested by mjg@ and the output is based on that
from Linux's "perf stat".

ioctl frontend ports.
This revision introduces two changes to CTL:
- Changes the way options are passed to CTL_LUN_REQ and CTL_PORT_REQ ioctls.
Removes ctl_be_arg structure and associated logic and replaces it with
nv(3)-based logic for passing in and out arguments.
- Allows creating multiple ioctl frontend ports using either ctladm(8) or
ctld(8).
New frontend ports are represented by /dev/cam/ctl<pp>.<vp> nodes, eg /dev/cam/ctl5.3.
Those device nodes respond only to CTL_IO ioctl.
New command-line options for ctladm:
# creates new ioctl frontend port with using free pp and vp=0
ctladm port -c
# creates new ioctl frontend port with pp=10 and vp=0
ctladm port -c -O pp=10
# creates new ioctl frontend port with pp=11 and vp=12
ctladm port -c -O pp=11 -O vp=12
# removes port with number 4 (it's a "targ_port" number, not pp number)
ctladm port -r -p 4
New syntax for ctl.conf:
target ... {
port ioctl/<pp>

}
target ... {

This commit adds a new debug server to bhyve. Unlike the existing -g
option which provides an efficient connection to a debug server
running in the guest OS, this debug server permits inspection and
control of the guest from within the hypervisor itself without
requiring any cooperation from the guest. It is similar to the debug
server provided by qemu.
To avoid conflicting with the existing -g option, a new -G option has
been added that accepts a TCP port. An IPv4 socket is bound to this
port and listens for connections from debuggers. In addition, if the
port begins with the character 'w', the hypervisor will pause the
guest at the first instruction until a debugger attaches and
explicitly continues the guest. Note that only a single debugger can
attach to a guest at a time.
Virtual CPUs are exposed to the remote debugger as threads. General
purpose register values can be read for each virtual CPU. Other
registers cannot currently be read, and no register values can be
changed by the debugger.
The remote debugger can read guest memory but not write to guest
memory. To facilitate source-level debugging of the guest, memory
addresses from the debugger are treated as virtual addresses (rather
than physical addresses) and are resolved to a physical address using
the active virtual address translation of the current virtual CPU.
Memory reads should honor memory mapped I/O regions, though the debug
server does not attempt to honor any alignment or size constraints
when accessing MMIO.
The debug server provides limited support for controlling the guest.
The guest is suspended when a debugger is attached and resumes when a
debugger detaches. A debugger can suspend a guest by sending a Ctrl-C
request (e.g. via Ctrl-C in GDB). A debugger can also continue a
suspended guest while remaining attached. Breakpoints are not yet
supported. Single stepping is supported on Intel CPUs that support
MTRAP VM exits, but is not available on other systems.
While the current debug server has limited functionality, it should
at least be usable for basic debugging now. It is also a useful
checkpoint to serve as a base for adding additional features.

COP allows fine-grained control on whether to offload a TCP connection
using t4_tom, and what settings to apply to a connection selected for
offload. t4_tom must still be loaded and IFCAP_TOE must still be
enabled for full TCP offload to take place on an interface. The
difference is that IFCAP_TOE used to be the only knob and would enable
TOE for all new connections on the inteface, but now the driver will
also consult the COP, if any, before offloading to the hardware TOE.
A policy is a plain text file with any number of rules, one per line.
Each rule has a "match" part consisting of a socket-type (L = listen,
A = active open, P = passive open, D = don't care) and a pcap-filter(7)
expression, and a "settings" part that specifies whether to offload the
connection or not and the parameters to use if so. The general format
of a rule is: [socket-type] expr => settings
Example. See cxgbetool(8) for more information.
[L] ip && port http => offload
[L] port 443 => !offload
[L] port ssh => offload
[P] src net 192.168/16 && dst port ssh => offload !nagle !timestamp cong newreno

[P] dst port http => offload
[A] dst port 443 => offload tls
[A] dst net 192.168/16 => offload !timestamp cong highspeed
The driver processes the rules for each new listen, active open, or
passive open and stops at the first match. There is an implicit rule at
the end of every policy that prohibits offload when no rule in the
policy matches:

Now that all of parsemsg() parses both RFC 3164 and 5424 messages and
hands them to logmsg(), alter the latter to properly forward all RFC
5424 message attributes to fprintlog(). While there, make some minor
cleanups to this code:
- Instead of extending the existing code that compares hostnames and
message bodies for deduplication, print all of the relevant message
fields into a single string that we can compare ('saved').
- No longer let the behaviour of fprintflog() depend on whether
'msg == NULL' to print repetition messages, Simply decompose this
function into fprintlog_first() and fprintlog_successive(). This
makes the interpretation of function arguments less magical and also
allows us to get consistent behaviour across RFC 3164 and 5424 when
adding support for the RFC 5424 output format.
- As RFC 5424 syslog messages have a dedicated application name field,
alter the repetition messages to be printed on behalf of syslogd on
the current system. Change these messages to use the local hostname,
so that it's obvious which syslogd instance detected the repetition.
Remove f_prevhost, as it has now become unnecessary.
- Remove a useless strdup(). Deconsting the message string is safe in
this specific case.
Syslogd currently uses the RFC 3164 format for its log messages.One
limitation of RFC 3164 is that it cannot be used to log entries with
sub-second precision timestamps. One of our users has expressed a desire
for doing this for doing some basic performance measurements.
This change attempts to make a first cut at switching to RFC 5424 based
logging. The first step is to alter syslogd's input path to properly
parse such messages. It alters the logmsg() prototype to match the
fields of RFC 5424. The parsemsg() function is extended to parse both
RFC 3164 and 5424 messages and call into logmsg() accordingly.
Additional changes include:
- Introducing proper parsing of timestamps, so that they can be printed
in any desired output format. This means we need to infer the year and
timezone for RFC 3164 timestamps.
- Removing ISKERNEL. This can now be realised by simply providing an
APP-NAME (== "kernel").
- Extending RFC 3164 parsing to trim off the TAG prefix and using that
