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.
2019-05-10wintun: fix scope of error objectJason A. Donenfeld
2019-05-10wintun: wait for interface registry key on device creationSimon Rozman
By using RegNotifyChangeKeyValue(). Also disable dead gateway detection. Signed-off-by: Simon Rozman <simon@rozman.si>

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?
2019-04-23tun: freebsd: work around numerous kernel panics on shutdownJason A. Donenfeld
There are numerous race conditions. But even this will crash it: while true; do ifconfig tun0 create; ifconfig tun0 destroy; done It seems like LLv6 is related, which we're not using anyway, so explicitly disable it on the interface.
2019-04-19setupapi: Fix struct size mismatchesSimon Rozman

2019-04-19setupapi: actually fix padding by rounding up to sizeof(void*)Jason A. Donenfeld
2019-04-19tun: darwin: write routeSocket variable in helperJason A. Donenfeld
Otherwise the race detector "complains".
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>

This reverts commit 52ec440d7977fad966002c3710ed9df957943407 and adds some spice.

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>

2019-03-04Simplify reading NetCfgInstanceId from registrySimon Rozman
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>
