device: add nil check before convert typed error back2020-05-01T14:49:10ZWenxuan Zhaoviz@linux.com2020-04-18T14:27:39Zurn:sha1:75a41b24ad2937169a6b4d0a2909dac1ffff726f
Since errors.As(err, target) returns false when err is nil,
which cause status set to 1 when no error occurs for Ipc{Get,Set}Operation.

device: move stats fields back down and add test diagnostics2020-04-07T05:55:53ZDavid Crawshawcrawshaw@tailscale.com2020-04-07T04:52:17Zurn:sha1:a4657f996d98378c06cc7da4d2c69539c19dae32
This reverts the movement of fields from d49f4e9.
That commit was cherry-picked from another branch where a field
had changed and misaligned the atomic fields. After cherry-picking,
moving the fields was no longer necessary but got dragged along.

Revert "device: use wgcfg key types"2020-04-07T05:52:41ZDavid Crawshawcrawshaw@tailscale.com2020-04-07T05:52:04Zurn:sha1:f6020a2085d9a6b911c00875752bb40bfe629e00
More cleanup work of wgcfg to do before bringing this in.
This reverts commit 83ca9b47b63b4d07630c4d579faf1111e42537d3.
device: remove racey read in session key rotation.2020-04-03T00:35:28ZDavid Andersondanderson@tailscale.com2020-03-11T00:52:50Zurn:sha1:ad256f0b739b835e8836f84571424cb4adc01b1e
This code was attempting to use the "compare racily, then lock
and compare again" idiom to try and reduce lock contention.
However, that idiom is not safe to use unless the comparison
uses atomic operations, which this does not.
This change simply deletes the racy read. This makes the code
correct, but potentially increases lock contention.

Useful in testing when bad network stacks repeat or
batch large numbers of packets.

This makes uapi.go's public API conform to Go style in terms
of error types.
