2017-10-12Use a temporary variable in rw_status() to dereference only once theMartin Pieuchot
volatile member of the struct. Not forcing a memory read on every access, 3 in this function, might reduce cache traffic in some cases. Micro-optimization and diff provided by Mateusz Guzik. ok visa@
2017-10-12Move sysctl_mq() where it can safely mess with mbuf queue internals.Martin Pieuchot
ok visa@, bluhm@, deraadt@
2017-10-12Fix a singed vs unsigned comparison resulting in an overflow of theMartin Pieuchot
routing socket. When clang became the default compiler, `if_flags' from `struct ifnet' was changed from "short" to "unsigned short", to silence a warning. Sadly the copy of these flags on the stack was still a "short" which made the flags comparison always true, which in turn made ifioctl() generates a RTM_INFO message for many ioctl(2). Since my last commit, the flag comparison is done for every ioctl(2). This made the kernel generate at least one routing message per ioctl, resulting in a lot of RTM_DESYNC. RTM_DESYNC problem reported by krw@ thanks to dhclient(8)'s noisiness! ok krw@, patrick@

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@
2017-10-11Try to make CPU cache size values more correct, especially on OCTEON IIVisa Hankala
and III. The logic does not look nice, but the parameters do not follow the standard config register layout anyway. Remove unnecessary default values, and assume that the Config1 and Config2 registers are available on every CPU. Tested on CN5020, CN6120, CN7130 and CN7360.

2017-10-11Move `kq_count' increase/decrease close to the corresponding TAILQ_*Martin Pieuchot
insert/remove operation. No functionnal change for the moment. However this helps to make this code mp-safe. Note that markers are still not, and wont be, counted. ok visa@, jsing@, bluhm@
2017-10-11Move kq_kev from struct kqueue to the stack.Martin Pieuchot
It turns this set of events per-thread without having to lock anything. From Dragonfly 10f6680a4f6684751aaae0965abfe140f19e9231 ok kettenis@, visa@, bluhm@

2017-10-10At reboot all vnodes are flushed, but when it sleeps, the updateAlexander Bluhm
process has a chance to create new dirty vnodes. Resolving soft dependencies adds vnodes to the dirty list. In softdep_flushfiles() vnodes and softdeps are flushed in a loop. But if they sleep, it is not guaranteed that all vnodes have been flushed when the softdep worklist flush reports that nothing has to be done. The solution is to do a final vnode flush after the softdep worklist has been flushed. Then the dirty list is empty and the final check in dounmount_leaf() does not panic with "unmount: dangling vnode". OK mikeb@

it with a simple ifdef that uses the inline keyword if being compiled with clang and doesn't use the keyword if being compiled with gcc. ok kettenis@

ok visa@
2017-10-09Turns out that the previous commit resolves the problem on Clang but atPatrick Wildt
the same time breaks the sparc64 build due to a very similar issue. To make it work, stop returning a huge struct and instead make the caller pass a pointer to the struct it allocated only once on the stack. Similar diff from sashan@ "yeah just make it work, and add it to the mop list" deraadt@

divert-packet. Bring back the loop over the global list to find the divert socket.
2017-10-06Kill the divert-packet socket option IP_DIVERTFL to filter packets.Alexander Bluhm
It used a loop over the global list divbtable that would be hard to make MP safe. The port net/dnsfilter does not work without this, it should be converted to divert-to. Neither other ports nor base use this filter feature. ports checked by sthen@; OK mpi@ benno@
2017-10-06The mount point flags were displayed in octal when printed by ddb.Alexander Bluhm
All other bit fields use hex as well as the MNT_ constants. Change this to hex to make it cosistent and less confusing. OK krw@
2017-10-06Recalibrate TSC timecounter with HPET and PM timerMike Belopuhov
If frequency of an invariant (non-stop) time stamp counter is measured using an independent working timecounter that has a known frequency, we can assume that the measured TSC frequency is as good as the resolution of the timecounter that we use to perform the measurement. This lets us switch from this high quality but expensive source to the cheaper TSC without sacrificing precision on a wide range of modern CPUs. From Adam Steen <adam@adamsteen.com.au> with tweaks from reyk@ and myself. Tested by brynet@, sthen@ and others, OK mlarkin, sthen
