the register values coming back from sigreturn(2). Normally this wouldn't
matter because the 32 bit environment would truncate the upper 32 bits
and re-save the truncated values at the next trap. However, if we got
a fast second signal and it was pending while we were returning from
sigreturn(2) in the signal trampoline, we'd never have had a chance to
truncate the bogus values in 32 bit mode, and the new sendsig would get
an EFAULT when trying to write to the bogus user stack address.
Functional changes:
- Cut struct source_hookinfo. Just use hook_p pointer.
- Remove "start_now" command. "start" command now requires number of
packets to send as argument. "start" command actually starts sending.
Move the code that actually starts sending from ng_source_rcvmsg()
to ng_source_start().
- Remove check for NG_SOURCE_ACTIVE in ng_source_stop(). We can be called
with flag cleared (see begin of ng_source_intr()).
- If NG_SEND_DATA_ONLY() use log(LOG_DEBUG) instead of printf(). Otherwise
we will *flood* console.
- Add ng_connect_t method, which sends NGM_ETHER_GET_IFNAME command
to "output" hook. Cut ng_source_request_output_ifp(). Refactor
ng_source_store_output_ifp() to use ifunit() and don't muck through
interface list.
- Add "setiface" command, which gives ability to configure interface
in case when ng_source_connect() failed. This happens, when we are not
connected directly to ng_ether(4) node.
- Remove KASSERTs, which can never fire.
- Don't check for M_PKTHDR in rcvdata method. netgraph(4) does this
for us.
Style:
- Assign sc_p = NG_NODE_PRIVATE(node) in declaration, to be
consistent with style of other nodes.
- Sort variables.
- u_intXX -> uintXX.
- Dots at ends of comments.

during authentication. Thus we need to call getpwnam *after* the user
has been authenticated. Colin mentioned that we should also move the
check for root in that case.
libalias.
In /usr/src/lib/libalias/alias.c, the functions LibAliasIn and
LibAliasOutTry call the legacy PacketAliasIn/PacketAliasOut instead
of LibAliasIn/LibAliasOut when the PKT_ALIAS_REVERSE option is set.
In this case, the context variable "la" gets lost because the legacy
compatibility routines expect "la" to be global. This was obviously
an oversight when rewriting the PacketAlias* functions to the
LibAlias* functions.
The fix (as shown in the patch below) is to remove the legacy
subroutine calls and replace with the new ones using the "la" struct
as the first arg.

- newbus plumbing. Each atapicam bus is a child off of a parent ata channel
bus. This is somewhat of a hack, but allows the ata core to be completely
free of atapicam knowledge.
- No more global lists of softc's and no more groping around in internal ata
structures on each command.
- Giant-free operation of the completion handler.
- Per-bus mutex for protecting the busy list and synchronizing detach.
- Lots of streamlining and dead code elimination, better adherence to the
CAM locking protocol.
This feature still requires that the appropriate atapi-* driver be present
for each atapi device that you want to talk to (i.e. atapi-cd for cdroms).
It does work both compiled into the kernel and as a loadable module.
