2025-01-31ssh,tempfork/gliderlabs/ssh: replace ↵Percy Wegmann12-22/+13
github.com/tailscale/golang-x-crypto/ssh with golang.org/x/crypto/ssh The upstream crypto package now supports sending banners at any time during authentication, so the Tailscale fork of crypto/ssh is no longer necessary. github.com/tailscale/golang-x-crypto is still needed for some custom ACME autocert functionality. tempfork/gliderlabs is still necessary because of a few other customizations, mostly related to TTY handling. Originally implemented in 46fd4e58a27495263336b86ee961ee28d8c332b7, which was reverted in b60f6b849af1fae1cf343be98f7fb1714c9ea165 to keep the change out of v1.80.

2022-11-04all: remove old +build tagsBrad Fitzpatrick5-5/+0
The //go:build syntax was introduced in Go 1.17: https://go.dev/doc/go1.17#build-lines gofmt has kept the +build and go:build lines in sync since then, but enough time has passed. Time to remove them. Done with: perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build') Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>

2022-03-26tempfork: temporarily fork gliderlabs/ssh and x/crypto/sshBrad Fitzpatrick20-0/+2790
While we rearrange/upstream things. gliderlabs/ssh is forked into tempfork from our prior fork at https://github.com/tailscale/ssh/commit/be8b7add4057ef5a8e458b42331a7633c06d026a x/crypto/ssh OTOH is forked at https://github.com/tailscale/golang-x-crypto because it was gnarlier to vendor with various internal packages, etc. Its git history shows where it starts (2c7772ba30643b7a2026cbea938420dce7c6384d).
