Jason A. Donenfeld 2e988467c2 wintun: work around GetInterface staleness bug 2019-05-03 00:42:36 +02:00
Jason A. Donenfeld 46dbf54040 wintun: don't retry when not creating 
The only time we're trying to counteract the race condition is when
we're creating a driver. When we're simply looking up all drivers, it
doesn't make sense to retry.

Jason A. Donenfeld 247e14693a wintun: try harder to open registry key 
This sucks. Can we please find a deterministic way of doing this
instead?

Simon Rozman 5811447b38 setupapi: Revise DrvInfoDetailData struct size calculation 
Go adds trailing padding to DrvInfoDetailData struct in GOARCH=386 which
confuses SetupAPI expecting exactly sizeof(SP_DRVINFO_DETAIL_DATA).

Simon Rozman 11f5780250 wintun: Revise interface creation wait 
DIF_INSTALLDEVICE returns almost immediately, while the device
installation continues in the background. It might take a while, before
all registry keys and values are populated.

Previously, wireguard-go waited for HKLM\SYSTEM\CurrentControlSet\
Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\<id> registry key
only.

Followed by a SetInterfaceName() method of Wintun struct which tried to
access HKLM\SYSTEM\CurrentControlSet\Control\Network\
{4D36E972-E325-11CE-BFC1-08002BE10318}\<id>\Connection registry key
might not be available yet.

This commit loops until both registry keys are available before
returning from CreateInterface() function.

Simon Rozman 9041d38e2d Simplify reading NetCfgInstanceId from registry 
As querying non-existing registry value and reading non-existing
registry string value both return ERROR_FILE_NOT_FOUND, we can
use later only.
