Joe Tsai c299a96624 all: apply consistent imports of "json" packages
This runs:

        go run ./cmd/jsonimports -update -ignore=tempfork/

which applies the following rules:

  * Until the Go standard library formally accepts "encoding/json/v2"
    and "encoding/json/jsontext" into the standard library
    (i.e., they are no longer considered experimental),
    we forbid any code from directly importing those packages.
    Go code should instead import "github.com/go-json-experiment/json"
    and "github.com/go-json-experiment/json/jsontext".
    The latter packages contain aliases to the standard library
    if built on Go 1.25 with the goexperiment.jsonv2 tag specified.

  * Imports of "encoding/json" or "github.com/go-json-experiment/json/v1"
    must be explicitly imported under the package name "jsonv1".
    If both packages need to be imported, then
    the former should be imported under the package name "jsonv1std".

  * Imports of "github.com/go-json-experiment/json"
    must be explicitly imported under the package name "jsonv2".

The latter two rules exist to provide clarity when reading code.
Without them, it is unclear whether "json.Marshal" refers to v1 or v2.
With them, however, it is clear that "jsonv1.Marshal" is calling v1 and
that "jsonv2.Marshal" is calling v2.

Brad Fitzpatrick 162d593514 net/flowtrack: fix, test String method
I meant to do this in the earlier change and had a git fail.

To atone, add a test too while I'm here.

Brad Fitzpatrick 9e0a5cc551 net/flowtrack: optimize Tuple type for use as map key
This gets UDP filter overhead closer to TCP. Still ~2x, but no longer ~3x.

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.

Brad Fitzpatrick a12aad6b47 all: convert more code to use net/netip directly
perl -i -npe 's,netaddr.IPPrefixFrom,netip.PrefixFrom,' $(git grep -l -F netaddr.)
    perl -i -npe 's,netaddr.IPPortFrom,netip.AddrPortFrom,' $(git grep -l -F netaddr. )
    perl -i -npe 's,netaddr.IPPrefix,netip.Prefix,g' $(git grep -l -F netaddr. )
    perl -i -npe 's,netaddr.IPPort,netip.AddrPort,g' $(git grep -l -F netaddr. )
    perl -i -npe 's,netaddr.IP\b,netip.Addr,g' $(git grep -l -F netaddr. )
    perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. )
    goimports -w .

Then delete some stuff from the net/netaddr shim package which is no
longer neeed.

Brad Fitzpatrick 6a396731eb all: use various net/netip parse funcs directly
Mechanical change with perl+goimports.

Changed {Must,}Parse{IP,IPPrefix,IPPort} to their netip variants, then
goimports -d .

Finally, removed the net/netaddr wrappers, to prevent future use.

Josh Bleecher Snyder 94fb42d4b2 all: use testingutil.MinAllocsPerRun
There are a few remaining uses of testing.AllocsPerRun:
Two in which we only log the number of allocations,
and one in which dynamically calculate the allocations
target based on a different AllocsPerRun run.

This also allows us to tighten the "no allocs"
test in wgengine/filter.
