2018-10-02Make some USB ioctls return ENXIO, instead of EIO, if usbd_is_dying().Stefan Sperling
Brings us one step closer towards making this condition's error code consistent across all USB drivers. Patch by Moritz Buhl ok mpi@ bluhm@

2015-11-25replace IFF_OACTIVE manipulation with mpsafe operations.David Gwynne
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@
2015-11-20shuffle struct ifqueue so in flight mbufs are protected by a mutex.David Gwynne
the code is refactored so the IFQ macros call newly implemented ifq functions. the ifq code is split so each discipline (priq and hfsc in our case) is an opaque set of operations that the common ifq code can call. the common code does the locking, accounting (ifq_len manipulation), and freeing of the mbuf if the disciplines enqueue function rejects it. theyre kind of like bufqs in the block layer with their fifo and nscan disciplines. the new api also supports atomic switching of disciplines at runtime. the hfsc setup in pf_ioctl.c has been tweaked to build a complete hfsc_if structure which it attaches to the send queue in a single operation, rather than attaching to the interface up front and building up a list of queues. the send queue is now mutexed, which raises the expectation that packets can be enqueued or purged on one cpu while another cpu is dequeueing them in a driver for transmission. a lot of drivers use IFQ_POLL to peek at an mbuf and attempt to fit it on the ring before committing to it with a later IFQ_DEQUEUE operation. if the mbuf gets freed in between the POLL and DEQUEUE operations, fireworks will ensue. to avoid this, the ifq api introduces ifq_deq_begin, ifq_deq_rollback, and ifq_deq_commit. ifq_deq_begin allows a driver to take the ifq mutex and get a reference to the mbuf they wish to try and tx. if there's space, they can ifq_deq_commit it to remove the mbuf and release the mutex. if there's no space, ifq_deq_rollback simply releases the mutex. this api was developed to make updating the drivers using IFQ_POLL easy, instead of having to do significant semantic changes to avoid POLL that we cannot test on all the hardware. the common code has been tested pretty hard, and all the driver modifications are straightforward except for de(4). if that breaks it can be dealt with later. ok mpi@ jmatthew@

2014-07-12Kill a bunch of DVACT_DEACTIVATE handlers whose only purpose were toMartin Pieuchot
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@
2013-12-07Some cleaning up of the ioctl handling bits to bring things in lineBrad Smith

2011-07-03Remove config_activate() and DVACT_ACTIVATE. PCMCIA's the only thingMatthew Dempsky
that's ever used it, and it's long since been changed to use DVACT_{QUIESCE,SUSPEND,RESUME} instead. ok deraadt@, dlg@; miod@ also agreed with this idea when I brought it up a few weeks ago

them from userland, and nothing in the kernel uses them. ok krw@, miod@
2011-01-16* instead of NULLing pointers to interface descriptors in the uaa, markJacob Meuser
interfaces as being claimed in the usbd_device's copy of the interface descriptors * allow ugen(4) to be attached if there are unused interfaces in a configuration that has had drivers attached * make ugen(4) aware that it may be sharing a device with (an)other driver(s), and if so: * do not let ugen(4) change the configuration * do not let ugen(4) access the already claimed interfaces discussed with deraadt and miod

2008-10-02First step towards cleaning up the Ethernet driver ioctl handling.Brad Smith
Move calling ether_ioctl() from the top of the ioctl function, which at the moment does absolutely nothing, to the default switch case. Thus allowing drivers to define their own ioctl handlers and then falling back on ether_ioctl(). The only functional change this results in at the moment is having all Ethernet drivers returning the proper errno of ENOTTY instead of EINVAL/ENXIO when encountering unknown ioctl's. Shrinks the i386 kernels by.. RAMDISK - 1024 bytes RAMDISKB - 1120 bytes RAMDISKC - 832 bytes Tested by martin@/jsing@/todd@/brad@ Build tested on almost all archs by todd@/brad@ ok jsing@

2008-03-13when attaching a cdce(4) device that does not have a proper mac address,Marc Balmer
use the tv_usec part of a getmicrotime(9) call instead of 'int ticks' to create a mac address. as ticks is 0 during boot, this resulted in both ends of a USB link cable to have the same mac address. problem found/diff tested winiger, feedback/ok deraadt
2007-10-11treat usb vendor/product names as a locator, and have usbd_print handle it,Theo de Raadt
so that it shows up before the :. as a result, all the usb devices do not need to have name printing code anymore. all this now works and prints nicely because usbd_probe_and_attach() is serialized. ok kettenis
