| message |
add kstat(4), a subsystem to let the kernel expose statistics to userland. a kstat is an arbitrary chunk of data that a part of the kernel wants to expose to userland. data could mean just a chunk of raw bytes, but generally a kernel subsystem will provide a series of kstat key/value chunks. this code is loosely modelled on kstat in solaris, but with a bunch of simplifications (we don't want to provide write support for example). the named or key/value structure is significantly richer in this version too. eg, ssolaris kstat named data supports integer types, but this version offers differentiation between counters (like the number of packets transmitted on an interface) and gauges (like how long the transmit queue is) and lets kernel providers say what the units are (eg, packets vs bytes vs cycles). the main motivation for this is to improve the visibility of what the kernel is doing while it's running. i wrote this as part of the recent work we've been doing on multiqueue and rss/toeplitz so i could verify that network load is actually spread across multiple rings on a single nic. without this we would be wasting memory and interrupt vectors on multiple rings and still just using the 1st one, and noone would know cos there's no way to see what rings are being used. another thing that can become visible is the different counters that various network cards provide. i'm particularly interested in seeing if packets get dropped because the rings aren't filled fully, which is an effect we've never really observed directly. a small part of wanting this is cos i spend an annoying amount of time instrumenting the kernel when hacking code in it. if most of the scaffolding for the instrumentation is already there, i can avoid repeatedly writing that code and save time. iterated a few times with claudio@ and deraadt@ |

| message |
Repair athn(4) in client mode against WPA2 access points. Client mode was subtly broken after support for CCMP offload was added. In client mode we should be using the first key table slot for our CCMP pairwise key, not an arbitrary slot based on our association ID (as is done in hostap mode). When the interface came up again after being reset the CCMP hardware engine was left in a non-working state. Apparently the key table was messed up or contained stale entries. Fix a potential timing issue in the code path which attempts to clear the key table on device power-up. For good measure, also clear the key table before the device is powered down. While here, fix off-by-ones in key table slot range checks. Problems reported by Tim Chase, Kevin Chadwick, Austin Hook, Stefan Kapfhammer. Fix tested by me on AR9280 (PCI) and AR9271 (USB) and Kevin Chadwick on AR9280 |

Add support for timeconting in userland. This diff exposes parts of clock_gettime(2) and gettimeofday(2) to userland via libc eliberating processes from the need for a context switch everytime they want to count the passage of time. If a timecounter clock can be exposed to userland than it needs to set its tc_user member to a non-zero value. Tested with one or multiple counters per architecture. The timing data is shared through a pointer found in the new ELF auxiliary vector AUX_openbsd_timekeep containing timehands information that is frequently updated by the kernel. Timing differences between the last kernel update and the current time are adjusted in userland by the tc_get_timecount() function inside the MD usertc.c file. This permits a much more responsive environment, quite visible in browsers, office programs and gaming (apparently one is are able to fly in Minecraft now). Tested by robert@, sthen@, naddy@, kmos@, phessler@, and many others! OK from at least kettenis@, cheloha@, naddy@, sthen@ |

IEEE1275 (Open Firmware) defines that parameter name strings can have a length of up to 31 characters. This limit is also present in the flattened device tree specification/ Unfortunately this limit isn't enforced by the tooling and there are systems in the wild that use longer strings. This includes the device trees used on POWER9 systems and has been seen on some ARM systems as well. So bump the buffer size from 32 bytes (31 + terminating NUL) to 64 bytes. Centrally define OFMAXPARAM to this value (in <dev/ofw/openfirm.h>) replacing the various OPROMMAXPARAM definition scattered around the tree to make sure the FDT implementation of OF_nextprop() uses the same buffer size as its consumers. Eliminate the static buffer in various openprom(4) implementations on FDT systems. Makes it possible to dump the full device tree on POWER9 systems using eeprom -p. ok deraadt@, visa@ |

Wire down the timekeep page. If we don't do this, the pagedaemon may page it out and bad things will happen when we try to page it back in from within the clock interrupt handler. While there, make sure we set timekeep_object back to NULL if we fail to make the timekeep page into kernel space. ok deraadt@ (who had a very similar diff) |
