state. Apparently it happens when both devices try to disconnect RFCOMM
multiplexor channel at the same time.
The scenario is as follows:
- local device initiates RFCOMM connection to the remote device. This
creates both RFCOMM multiplexor channel and data channel;
- remote device terminates RFCOMM data channel (inactivity timeout);
- local device acknowledges RFCOMM data channel termination. Because
there is no more active data channels and local device has initiated
connection it terminates RFCOMM multiplexor channel;
- remote device does not acknowledges RFCOMM multiplexor channel
termination. Instead it sends its own request to terminate RFCOMM
multiplexor channel. Even though local device acknowledges RFCOMM
multiplexor channel termination the remote device still keeps
L2CAP connection open.
Because of hanging RFCOMM multiplexor channel subsequent RFCOMM
connections between local and remote devices will fail.

The original might have pointers to user-specified strings;
copying the string (instead of just the pointer) protects against
the client re-using their own buffers.
I'm trying hard to avoid dumping all of the 'set' string functions
in favor of slower, but more predictable 'copy' semantics.
ip_id again. ip_id is already set to the ip_id of the encapsulated packet.
Make a comment about mbuf allocation failures more realistic.

resource pre-allocation. The problem is that the BARs of the EBus bridges
contain the ranges for the resources for the EBus devices beyond the bridge.
So when the EBus code tries to allocate the resource for an EBus device
it's already allocated by the PCI code.
To be removed again as soon as we have a proper solution in the EBus Code.

at startup because ipfilter is not yet enabled (using the device results
too early results in ENXIO.)
source address of a packet exists in the routing table. The
default route is ignored because it would match everything and
render the check pointless.
This option is very useful for routers with a complete view of
the Internet (BGP) in the routing table to reject packets with
spoofed or unrouteable source addresses.
Example:
ipfw add 1000 deny ip from any to any not versrcreach

secondary bus is 0, we program the primary bus, the secondary bus and
the suborindate bus. This isn't ideal, since we start at parent_bus +
1 and store this in a static.
Ideally, we'd walk the tree and assign bus numbers. However, that's
harder to accomplish without some help from the bus layer which we're
not planning on doing that until 6.
This fixes my CardBus problems on my Sony PCG-Z1WA, and might fix the
Dells that have had problems.
sched_ule, in January 2004. Looking at this, "pagezero" is (one of) the
culprit(s). We had no provision for processes with P_NOLOAD set. With
pagezero not running at PRI_ITHD, kseq_load_{add,rem} count pagezero as
another-normal-process, thus the "expected-plus-one" load reported in
the above thread.

My original instinct to make ndis_return_packet() asynchronous was correct.
Making ndis_rxeof() submit packets to the stack asynchronously fixes
one recursive spinlock acquisition, but it's also possible for it to
happen via the ndis_txeof() path too. So:
- In if_ndis.c, revert ndis_rxeof() to its old behavior (and don't bother
putting ndis_rxeof_serial() back since we don't need it anymore).
- In kern_ndis.c, make ndis_return_packet() submit the call to the
MiniportReturnPacket() function to the "ndis swi" thread so that
it always happens in another context no matter who calls it.
workaround was for hardware where the clock was not latched, not for
hardware that was too slow. Also, make variable names more specific for ddb
printing.
adjunct maps are used. One symtom of this bug is sshd saying:
login_get_lastlog: Cannot find account for uid X
when logging in. The problem here is caused by an incorrect reuse of the rv
variable when previous values are needed later.
While I would have prefered to have a solution that didn't move
knowledge of this into the pci layer. However, this is literally the
only exception that's listed in the PCI standard to the usual way of
decoding BARs. atapci devices in legacy mode now ignore the first 4
bars and hard code the values to the legacy ide values (well, for each
of the controllers that are in legacy mode). The 5th bar is handled
normally.
Remove the zero bar handling. zero bars should be ignored at all
other times, and since we handle that specially, we don't need the
older workaround.
