It's very slow, but unfortunately we haven't a choice. NLA needs this to have completed.

2019-05-31tun: windows: mitigate infinite loop in Flush()Jason A. Donenfeld1-29/+35
It's possible that for whatever reason, we keep returning EOF, resulting in repeated close/open/write operations, except with empty packets.

2019-05-24wintun: revise GetInterface()Simon Rozman2-3/+6
- 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: revise value readingSimon Rozman2-67/+82
- 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>
