Anton Tolchanov	781f79408d	ipn/ipnlocal: allow multiple signature chains from the same SigCredential Detection of duplicate Network Lock signature chains added in `01847e0123` failed to account for chains originating with a SigCredential signature, which is used for wrapped auth keys. This results in erroneous removal of signatures that originate from the same re-usable auth key. This change ensures that multiple nodes created by the same re-usable auth key are not getting filtered out by the network lock.

Anton Tolchanov	4651827f20	tka: test SigCredential signatures and netmap filtering This change moves handling of wrapped auth keys to the `tka` package and adds a test covering auth key originating signatures (SigCredential) in netmap.

Anton Tolchanov	01847e0123	ipn/ipnlocal: discard node keys that have been rotated out A non-signing node can be allowed to re-sign its new node keys following key renewal/rotation (e.g. via `tailscale up --force-reauth`). To be able to do this, node's TLK is written into WrappingPubkey field of the initial SigDirect signature, signed by a signing node. The intended use of this field implies that, for each WrappingPubkey, we typically expect to have at most one active node with a signature tracing back to that key. Multiple valid signatures referring to the same WrappingPubkey can occur if a client's state has been cloned, but it's something we explicitly discourage and don't support: https://tailscale.com/s/clone This change propagates rotation details (wrapping public key, a list of previous node keys that have been rotated out) to netmap processing, and adds tracking of obsolete node keys that, when found, will get filtered out.

Brad Fitzpatrick	7c1d6e35a5	all: use Go 1.22 range-over-int Updates #11058 Change-Id: I35e7ef9b90e83cac04ca93fd964ad00ed5b48430 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	7 months ago
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

Tom DNetto	e8a11f6181	tka: make rotation signatures use nested keyID Duplicating this at each layer doesnt make any sense, and is another invariant where things could go wrong. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago

Tom DNetto	be95aebabd	tka: implement credential signatures (key material delegation) This will be needed to support preauth-keys with network lock in the future, so getting the core mechanics out of the way now. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago
