Here’s an early version of a task queue based approach:
http://people.freebsd.org/~kp/0001-bridge-Cope-with-if_ioctl-s-that-sleep.patch
That still needs to be cleaned up, but this should resolve the
sleep issue and the LOR.
There are some issues... seems like inside a jail I can't ping
systems outside of the hardware.
Bridge setup:
- member jail A
- member jail B
- member external_if of host
If I ping the router from the host, it works. If I ping from one
jail to another, it works. If I ping from the jail to the IP of
the external_if, it works. If I ping from a jail to the router, I
do not get a response.
Can you check for 'failed ifpromisc' error messages in dmesg? And
verify that all bridge member interfaces are in promiscuous mode?
I have a panic for you...:
- startup still in progress = 22 jails in startup, somewhere after a
few jails started the panic happened
- tcpdump was running on the external interface
- a ping to a jail IP from another system was running, the first
ping went through, then it paniced
First regarding your questions about promisc mode: no error, but the
promisc mode is directly disabled again on all interfaces.
I think I see why you had issues with the promiscuous setting. I’ve
updated the patch to be even more horrific than it was before.
Hmmm.... same behavior as before.
I haven't kept the old version of the patch, so I can't compare if I
somehow downloaded the old version again, or if I got the updated
one...
Okay, let’s abandon that patch. It’s ugly and it doesn’t work.
Here’s a different approach that I’m much happier with.
https://people.freebsd.org/~kp/0001-bridge-Call-member-interface-ioctl-without-NET_EPOCH.patch
It passes the regression tests with WITNESS and INVARIANTS enabled, and
a hack in the epair ioctl() handler to make it sleep (to look a bit like
the Intel ioctl() handler that currently trips up if_bridge).
Best,
Kristof
