* net80211: stub SIOCS80211SCAN, make ifconfig scan instant.pirofti2018-04-261-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The following removes the functionality of the SIOCS80211SCAN ioctl. After long discussions with stps@, mpi@, and deraadt@ we decided that this was the correct way of fixing ifconfig scan from blocking the network stack. The kernel will continue scanning in the background and filling the nodes array, but ifconfig scan commands will now basically do just a SIOCG80211ALLNODES and pretty print the array. So the output stays the same but is instant. In fact, when the interface is freshly brought up, if you type fast enough, you can see the array being filled by running multiple ifconfig scans in sequence. The SIOCS80211SCAN ioctl stays for now as wi(4), pgt(4) and malo(4) still need it around. But not for long... Another change that this introduces is the fact that ifconfig scan no longer plays with UP and DOWN. If the interface is down it complains and exits. This is needed in order to maintain the nodes list. Works on iwm(4), iwn(4), urtwn(4), run(4) and athn(4). Tested by mpi@, landry@, florian@, thanks! OK mpi@.

* replace IFF_OACTIVE manipulation with mpsafe operations.dlg2015-11-251-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | there are two things shared between the network stack and drivers in the send path: the send queue and the IFF_OACTIVE flag. the send queue is now protected by a mutex. this diff makes the oactive functionality mpsafe too. IFF_OACTIVE is part of if_flags. there are two problems with that. firstly, if_flags is a short and we dont have any MI atomic operations to manipulate a short. secondly, while we could make the IFF_OACTIVE operates mpsafe, all changes to other flags would have to be made safe at the same time, otherwise a read-modify-write cycle on their updates could clobber the oactive change. instead, this moves the oactive mark into struct ifqueue and provides an API for changing it. there's ifq_set_oactive, ifq_clr_oactive, and ifq_is_oactive. these are modelled on ifsq_set_oactive, ifsq_clr_oactive, and ifsq_is_oactive in dragonflybsd. this diff includes changes to all the drivers manipulating IFF_OACTIVE to now use the ifsq_{set,clr_is}_oactive API too. ok kettenis@ mpi@ jmatthew@ deraadt@
* No need to include <net/if_arp.h>mpi2015-11-241-2/+1
| | | | | | | | | This header is only needed because <netinet/if_ether.h> declares a structure that needs it. But it turns out that <net/if.h> already includes it as workaround. A proper solution would be to stop declarting "struct ether_arp" there. But no driver should need this header.

| | | | | | | | | | | | | | set the 'dying' flag of a device. Such handlers are useless now that usbd_detach() already set this flag. Even if the purpose of this flag is questionnable on OpenBSD because DVACT_DEACTIVATE acts as a pre-detach event, this is just a first small step towards the simplification of the autoconf(9) device states. This cleaning is now possible thanks to the work of pirofti@ to convert all the USB drivers to properly use usbd_is_dying(). Discussed many times with deraadt@
