2019-08-31Fix a bug of the tap-detection code.Ulf Brosziewski
Do not switch from the DETECT state to IGNORE when the last (active) touch has been released. Otherwise, depending on how events are reported and synchronized, it may happen that the handler does not switch back to DETECT when necessary.

2019-07-01Use timeout_add_msec(9)kn
Trivial conversion from ticks to milliseconds where macros already come in milliseconds and timeout values only need reduction by hz to use the new API. OK mpi
2019-05-24Remove redundant conditional. Inspecting flags is the correct way toanton
determine if the device was opened in read/write mode. ok mpi@ visa@
2019-05-22Cleanup debug macros in wscons. Favor __func__ over spelling out the actualanton
function name in order to reduce grep noise. Also, some of them where referring to the wrong function.
2019-05-22A wscons device may only be opened in read/write mode once. However,anton
after checking for exclusive access, malloc() can sleep in wsevent_init() opening up for a potential race where more than one thread may be able open the device. Prevent this by checking if the race was won after calling malloc(). While here, switch to mallocarray as proposed by both cheloha@ and mpi@ ok mpi@
2019-05-21A problem fixed in wskbd is also present in wsmux. Repeating theanton
previous commit message: In wsmuxclose(), use the same logic as in wsmuxopen() to determine if the device was opened in write-only mode. Relying on me_evar being NULL does not work if the wsmux device was opened first followed attaching it to another wsmux. Closing the wsmux device first at this stage would cause the wscons_event queue inherited from the parent wsmux to be freed. This in turn could cause a panic if an ioctl(WSMUXIO_INJECTEVENT) command is issued on parent wsmux device. ok mpi@ visa@ Reported-by: syzbot+f6c2ed7901eb4b970720@syzkaller.appspotmail.com

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@
2019-03-30Restrict the number of allowed wsmux devices, just like wskbd and wsmouseanton

2019-03-24Add new event types for precision scrolling.Ulf Brosziewski
2019-03-16Clear the me_evp pointer after calling wsmux_do_close() as opposed ofanton
before. The pointer indicates if a wsmux device is attached to another wsmux, clearing it therefore allows same device to attached again. This can be problematic since wsmux_do_close() can sleep. Swapping the order of operations prevents attaching a wsmux which is in a closing state. ok deraadt@ mpi@ visa@
2019-03-02Limited the number of allowed stacked wsmux devices. A sufficiently long chainanton
of such devices can exhaust the kernel stack due to wsmux_do_open() being recursive. While here, serialize the operation of stacking a wsmux device. Joint effort with and ok visa@
2019-02-20When adding a wsmux device to an existing wsmux device usinganton
ioctl(WSMUXIO_ADD_DEVICE), two distinct locks of the same type are acquired. Thus, witness will emit warning. Since acquiring two different locks of the same type is harmless in this context, relax the witness check by flagging the locks as RWL_DUPOK. ok visa@ Reported-by: syzbot+249e483406a1f7843915@syzkaller.appspotmail.com

2019-02-18Serialize access to the list of attached child devices belonging to aanton

2018-11-19Utilize sigio with wscons. The old behavior of always making the process groupanton
of the process who opens the device the default recipient of sigio is removed as a side-effect of this change. Issuing ioctl(FIOSETOWN) is therefore mandatory in order to receive sigio, which is more consistent with other subsystems supporting sigio. This change is all made possible by the new sigio(9) API and prevents wscons from keeping a pointer to the recipient process. Usage of such pointer could cause a panic since wscons is not inform on process deallocation, leaving a dangling pointer behind. ok mpi@ visa@

2018-01-13coordinate again: polishingUlf Brosziewski
2018-01-11Improve the handling of coordinate inputs and filters.Ulf Brosziewski
Single-touch and multi-touch coordinate inputs are treated more uniformly, and the hysteresis filters have a more consistent implementation. If possible, pointer control will be assigned to touches with coordinate updates that pass the default hysteresis filter (the function has been moved to wsmouse.c). The "strong" variant of hysteresis has been improved, the new version won't double the threshold when a movement changes the orientation on an axis. There is an additional change in wstpad_configure, which ensures that a zero size disables an edge area even if the coordinate limits are misconfigured.
