2019-05-04Improve the interaction between efifb(4), inteldrm(4) and radeondrm(4)Mark Kettenis
when we have a serial console by introducing the notion of a "primary" graphics device. The primary graphics device is the one set up and used by firmware (BIOS, UEFI). The goal is to make sure that wsdisplay0 and drm0 reliably attach to the primary graphics device such that X works out of the box even if you have multiple cards or if you are using a serial console. This also fixes the situation where inteldrm(4) or radeondrm(4) would take over the console on UEFI systems even if the kernel was booted with a serial console. ok jsg@

2019-04-22disable mobileip(4)David Gwynne
it's not great in several dimensions, so this is a first step to removing it. if noone has a (reasonable) teary i'll start removing the code in a few weeks. "kill it with fire" deraadt@
2019-04-20as discussed with beck, crank dma-range bufcache to a high numberTheo de Raadt
(he suggested 90 but I prefer 80). This is so we learn the downside from user reports.

2019-03-18Add kubsan(4), a undefined behavior sanitizer for the kernel. It'santon
capable of detecting undefined behavior at runtime and all findings are printed to the system console, including the offending line in the source code. kubsan is limited to architectures using Clang as their default compiler and is not enabled by default. Derived from the NetBSD implementation. ok kettenis@ visa@

2019-02-26Introduce safe memory reclamation, a mechanism for reclaiming sharedVisa Hankala
objects that readers can access without locking. This provides a basis for read-copy-update operations. Readers access SMR-protected shared objects inside SMR read-side critical section where sleeping is not allowed. To reclaim an SMR-protected object, the writer has to ensure mutual exclusion of other writers, remove the object's shared reference and wait until read-side references cannot exist any longer. As an alternative to waiting, the writer can schedule a callback that gets invoked when reclamation is safe. The mechanism relies on CPU quiescent states to determine when an SMR-protected object is ready for reclamation. The <sys/smr.h> header additionally provides an implementation of singly- and doubly-linked lists that can be used together with SMR. These lists allow lockless read access with a concurrent writer. Discussed with many OK mpi@ sashan@
2018-12-20add bpe(4) or Backbone Provider Edge interfacesDavid Gwynne
Backbone refers to 802.1ah or 802.1Q Provider Backbone Bridges (PBB), or mac-in-mac, which is like vlans except it completely encapsulates the inner packet rather than just add a shim to it. This removes the need for Backbone Core Bridges (ie, switches between bpe instances) to know all the addresses on all the networks.

2018-08-21Rework kcov kernel config. Instead of treating kcov as both an option and aanton
pseudo-device, get rid of the option. Enabling kcov now requires the following line to be added to the kernel config: pseudo-device kcov 1 This is how pseudo devices are enabled in general. A side-effect of this change is that dev/kcov.c will no longer be compiled by default. Prodded by deraadt@; ok mpi@ visa@

2018-07-13Unveiling unveil(2).Bob Beck
This brings unveil into the tree, disabled by default - Currently this will return EPERM on all attempts to use it until we are fully certain it is ready for people to start using, but this now allows for others to do more tweaking and experimentation. Still needs to send the unveil's across forks and execs before fully enabling. Many thanks to robert@ and deraadt@ for extensive testing. ok deraadt@

2018-02-07split mobileip(4) out from the gre(4) driver.David Gwynne
having mobileip in gre makes it hard to cut gre up. the current mobileip code is also broken, so this is def and improvement. it also makes it easy to disable and remove mobileip in the future. ok claudio@ henning@
2018-02-06syncookies for pf.Henning Brauer
when syncookies are on, pf will blindly answer each and every SYN with a syncookie-SYNACK. Upon reception of the ACK completing the 3WHS, pf will reconstruct the original SYN, shove it through pf_test, where state will be created if the ruleset permits it. Then massage the freshly created state (we won't see the SYNACK), set up the sequence number modulator, and call into the existing synproxy code to start the 3WHS with the backend host. Add an - somewhat basic for now - adaptive mode where syncookies get enabled if a certain percentage of the state table is filled up with half-open tcp connections. This makes pf firewalls resilient against large synflood attacks. syncookies are off by default until we gained more experience, considered experimental for now. see http://bulabula.org/papers/2017/bsdcan/ for more details. joint work with sashan@, widely discussed and with lots of input by many

TCP_FACK was disabled by provos@ in June 1999. TCP_FACK is an algorithm that decides that when something is lost, all not SACKed packets until the most forward SACK are lost. It may be a correct estimate, if network does not reorder packets. OK visa@ mpi@ mikeb@

2017-10-11Add bwfm(4), a driver for Broadcom FullMAC WiFi controllers. ThePatrick Wildt
FullMAC, in comparison to SoftMAC, does most WiFi handling in the firmware that's running on the controller. This means we have to work around the net80211 stack while still implementing all the WiFi interfaces to userland. This driver is still in early development. So far it can connect to open WiFis over the USB bus. SDIO and PCIe support, for devices like the Raspberry Pi 3 or the Macbooks, is not yet implemented. Also mbufs on the transmit path leak and are not yet freed. ok stsp@
