* Add workaround for fxp issue at interface initialization with IPv6.Yoshinobu Inoue2000-02-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Some LAN card chip for fxp is known to cause problem at interface initialization with IPv6 enabled. It happens at some delicate timing. And also, just adding some DELAY before IPv6 address autoconfiguration is known to avoid the problem. Complete fix is changing the driver not to use interrupt at multicast filter initialization, but trying such change in this stage will be dangerous. So I add some DELAY() only inside #ifdef INET6 part, as temporal workaround only for 4.0.

* Attempt to fix a problem with receiving packets on USB ethernet interfaces.Bill Paul2000-01-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Packets are received inside USB bulk transfer callbacks, which run at splusb() (actually splbio()). The packet input queues are meant to be manipulated at splimp(). However the locking apparently breaks down under certain circumstances and the input queues can get trampled. There's a similar problem with if_ppp, which is driven by hardware/tty interrupts from the serial driver, but which must also manipulate the packet input queues at splimp(). The fix there is to use a netisr, and that's the fix I used here. (I can hear you groaning back there. Hush up.) The usb_ethersubr module maintains a single queue of its own. When a packet is received in the USB callback routine, it's placed on this queue with usb_ether_input(). This routine also schedules a soft net interrupt with schednetisr(). The ISR routine then runs later, at splnet, outside of the USB callback/interrupt context, and passes the packet to ether_input(), hopefully in a safe manner. The reason this is implemented as a separate module is that there are a limited number of NETISRs that we can use, and snarfing one up for each driver that needs it is wasteful (there will be three once I get the CATC driver done). It also reduces code duplication to a certain small extent. Unfortunately, it also needs to be linked in with the usb.ko module in order for the USB ethernet drivers to share it. Also removed some uneeded includes from if_aue.c and if_kue.c Fix suggested by: peter Not rejected as a hairbrained idea by: n_hibma Notes: svn path=/head/; revision=55789

| | | | | | | | | | | | | | | | | possible for ro->ro_rt to be non-NULL even though the RTF_UP flag is cleared. (Example: a routing daemon or the "route" command deletes a cloned route in active use by a TCP connection.) In that case, the code was clobbering a reference to the routing table entry without decrementing the entry's reference count. The splnet() call probably isn't needed, but I haven't been able to prove that yet. It isn't significant from a performance standpoint since it is executed very rarely.

This allows control messages to be sent and received in ASCII form using ngctl(8), which makes ngctl a lot more useful. This also allows all the type-specific debugging code in libnetgraph to go away -- instead, we just ask the node itself to do the ASCII translation for us. Currently, all generic control messages are supported, as well as messages associated with the following node types: async, cisco, ksocket, and ppp. See /usr/share/examples/netgraph/ngctl for an example of using this. Also give ngctl(8) the ability to print out incoming data and control messages at any time. Eventually nghook(8) may be subsumed. Several other misc. bug fixes.
