2019-06-05wintun: don't run HrRenameConnection in separate threadJason A. Donenfeld
It's very slow, but unfortunately we haven't a choice. NLA needs this to have completed.

2019-06-04setupapi: define PropChangeParams structSimon Rozman
This structure is required for calling DIF_PROPERTYCHANGE installer class. Signed-off-by: Simon Rozman <simon@rozman.si>
2019-05-24wintun: revise GetInterface()Simon Rozman
- Make foreign interface found error numeric to ease condition detection. - Update GetInterface() documentation. - Make tun.CreateTUN() quit when foreign interface found before attempting to create a Wintun interface with a duplicate name. Creation is futile. Signed-off-by: Simon Rozman <simon@rozman.si>

2019-05-11wintun: registry: fix nitsJason A. Donenfeld
2019-05-11wintun: registry: revise value readingSimon Rozman
- Make getStringValueRetry() reusable for reading any value type. This merges code from GetIntegerValueWait(). - expandString() >> toString() and extend to support REG_MULTI_SZ (to return first value of REG_MULTI_SZ). Furthermore, doing our own UTF-16 to UTF-8 conversion works around a bug in windows/registry's GetStringValue() non-zero terminated string handling. - Provide toInteger() analogous to toString() - GetStringValueWait() tolerates and reads REG_MULTI_SZ too now. It returns REG_MULTI_SZ[0], making GetFirstStringValueWait() redundant. Signed-off-by: Simon Rozman <simon@rozman.si>

2019-05-10wintun: IpConfig is a MULTI_SZ, and fix errorsJason A. Donenfeld
2019-05-10wintun: poll for device keyJason A. Donenfeld
It's actually pretty hard to guess where it is.

2019-05-03wintun: work around GetInterface staleness bugJason A. Donenfeld
2019-05-02wintun: don't retry when not creatingJason A. Donenfeld
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.
2019-04-29wintun: try harder to open registry keyJason A. Donenfeld
This sucks. Can we please find a deterministic way of doing this instead?

2019-04-19setupapi: actually fix padding by rounding up to sizeof(void*)Jason A. Donenfeld
2019-04-18setupapi: Revise DrvInfoDetailData struct size calculationSimon Rozman
Go adds trailing padding to DrvInfoDetailData struct in GOARCH=386 which confuses SetupAPI expecting exactly sizeof(SP_DRVINFO_DETAIL_DATA). Signed-off-by: Simon Rozman <simon@rozman.si>

2019-03-07wintun: Revise interface creation waitSimon Rozman
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. Signed-off-by: Simon Rozman <simon@rozman.si>

As querying non-existing registry value and reading non-existing registry string value both return ERROR_FILE_NOT_FOUND, we can use later only. Signed-off-by: Simon Rozman <simon@rozman.si>
