Both bugs where reported by Valentin Nechayev. The first bug results in a kernel panic.

Reviewed by: scottl r199997 | gibbs Add media ioctl support and link notifications so that devd will attempt to run dhclient on a netfront (xn) device that is setup for DHCP in /etc/rc.conf. PR: kern/136251 (fixed differently than the submitted patch) r204158 | kmacy - make printf conditional - fix witness warnings by making configuration lock a mutex r207673 | joel Switch to our preferred 2-clause BSD license. Approved by: kmacy r208901 | ken A number of netfront fixes and stability improvements: - Re-enable TSO. This was broken previously due to CSUM_TSO clearing the CSUM_TCP flag, so our checksum flags were incorrectly set going to the netback driver. That was fixed in r206844 in tcp_output.c, so we can turn TSO back on here. - Fix the way transmit slots are calculated, so that we can't overfill the ring. - Avoid sending packets with more fragments/segments than netback can handle. The Linux netback code can only handle packets of MAX_SKB_FRAGS, which turns out to be 18 on machines with 4K pages. We can easily generate packets with 32 or so fragments with TSO turned on. Right now the solution is just to drop the packets (since netback doesn't seem to handle it gracefully), but we should come up with a way to allow a driver to tell the TCP stack the maximum number of fragments it can handle in a single packet. - Fix the way the consumer is tracked in the receive path. It could get out of sync fairly easily. - Use standard Xen ring macros to make it clearer how netfront is using the rings. - Get rid of Linux-ish negative errno return values. - Added more documentation to the driver. - Refactored code to make it easier to read. - Some other minor fixes.

It seems that historical behaviour is to not reporting exception on EOF, and several applications are broken.
