* bhyve: do not exit if LPC finds no host selectorCorvin Köhne2023-04-111-7/+10
| | | | | | | | | | | | The host selector is only required when the user likes to use the same LPC device IDs as the physical LPC device. This is an uncommon use case. For that reason, it makes no sense to exit when we don't find the host selector. Reviewed by: markj MFC after: 1 week Sponsored by: Beckhoff Automation GmbH & Co.

* dhclient: add ability to ignore options in offersRob Norris2023-04-106-3/+25
| | | | | | | | | | | | | | | | | | | | | | | | | A machine might exist on multiple networks, all of which offer, say, default routes or name servers. There's no easy way to indicate in the config that those options are only valid for a single interface. Now, we can write: interface "lan0" { request routers; require routers; } interface "lan1" { ignore routers; } And only take action on default routes offered on lan0.

* tcp: Rack - in the absence of LRO fixed rate pacing (loopback or interfaces ↵Randall Stewart2023-04-101-1/+53
| | | | | | | | | | | | | | | with no LRO) does not work correctly. Rack is capable of fixed rate or dynamic rate pacing. Both of these can get mixed up when LRO is not available. This is because LRO will hold off waking up the tcp connection to processing the inbound packets until the pacing timer is up. Without LRO the pacing only sort-of works. Sometimes we pace correctly, other times not so much. This set of changes will make it so pacing works properly in the absence of LRO.

* bridge: Add support for emulated netmap modeMark Johnston2023-04-105-10/+134
| | | | | | | | | | | | | | | | | | | | | | | | | if_bridge receives packets via a special interface, if_bridge_input, rather than by if_input. Thus, netmap's usual hooking of ifnet routines does not work as expected. Instead, modify bridge_input() to pass packets directly to netmap when it is enabled. This applies to both locally delivered packets and forwarded packets. When a netmap application transmits a packet by writing it to the host TX ring, the mbuf chain is passed to if_input, which ordinarily points to ether_input(). However, when transmitting via if_bridge, bridge_input() needs to see the packet again in order to decide whether to deliver or forward. Thus, introduce a new protocol flag, M_BRIDGE_INJECT, which 1) causes the packet to be passed to bridge_input() again after Ethernet processing, and 2) avoids passing the packet back to netmap. The source MAC address of the packet is used to determine the original "receiving" interface.

* usb(4): Separate the fast path and the slow path to avoid races and ↵Hans Petter Selasky2023-04-084-41/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | use-after-free for the USB FS interface. Bad behaving user-space USB applicatoins may crash the kernel by issuing USB FS related ioctl(2)'s out of their expected order. By default the USB FS ioctl(2) interface is only available to the administrator, root, and driver applications like webcamd(8) needs to be hijacked in order for this to happen. The issue is the fast-path code does not always see updates made by the slow-path code, and may then work on freed memory. This is easily fixed by using an EPOCH(9) type of synchronization mechanism. A SX(9) lock will be used as a substitute for EPOCH(9), due to the need for sleepability. In addition most calls going into the fast-path originate from a single user-space process and the need for multi-thread performance is not present.

The Linux Kerberized NFSv4.1/4.2 mounts currently work without support for this because Linux will fall back to SP4_NONE, but there is no guarantee this fallback will work forever. This commit only affects Kerberized NFSv4.1/4.2 mounts from Linux at this time. MFC after: 3 months
