Will Norris	71029cea2d	all: update copyright and license headers ... This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago

Eng Zer Jun	f0347e841f	refactor: move from io/ioutil to io and os packages ... The io/ioutil package has been deprecated as of Go 1.16 [1]. This commit replaces the existing io/ioutil functions with their new definitions in io and os packages.

David Crawshaw	15b8665787	tka: stable text representation of AUMHash ... This makes debugging easier, you can pass an AUMHash to a printf and get a string that is easy to debug. Also rearrange how directories/files work in the FS store: use the first two characters of the string representation as the prefix directory, and use the entire AUMHash string as the file name. This is again to aid debugging: you can `ls` a directory and line up what prints out easily with what you get from a printf in debug code.

Tom DNetto	4001d0bf25	assorted: plumb tka initialization & network-lock key into tailscaled ... - A network-lock key is generated if it doesn't already exist, and stored in the StateStore. The public component is communicated to control during registration. - If TKA state exists on the filesystem, a tailnet key authority is initialized (but nothing is done with it for now).

Tom DNetto	ec4f849079	tka: implement filesystem-based tailchonk implementation ... FS implements Chonk, and given the expected load characteristics (frequent use of AUM() + ChildAUMs(), and infrequent use of Heads() + CommitVerifiedAUMs()), the implementation avoids scanning the filesystem to service AUM() and ChildAUMs().

Tom DNetto	cca25f6107	tka: implement Chonk type & an in-memory implementation ... Chonks are responsible for efficient storage of AUMs and other TKA state. For testing/prototyping I've implemented an in-memory version, but once we start to use this from tailscaled we'll need a file-based version. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago
