tls: emit a warning when `servername` is an IP address #23329

oyyd · 2018-10-08T08:19:29Z

Setting the TLS ServerName to an IP address is not permitted by RFC6066. This will be ignored in a future version.

This PR is basing on #18127 and should be semver-major.

replace replace RFC6066 with [RFC 6066][]

Nit: I'd move this out of the 'listening' listener.

Is this assertion needed for this test?

No. It's copied from another test.

sam-github · 2018-10-09T22:31:49Z

The docs just use the phrase "server name" without making clear that it must not be an IP address. It would be helpful to have in addition to this a PR to document that server name must not be an IP. That doc change would be semver-patch.

@oyyd This might need another rebase because of 1523111 (but that one in turn needs fixing up because it missed assigning the deprecation code… maybe wait a couple hours until that is resolved? :/)

oyyd · 2018-10-26T04:37:06Z

@addaleax I will rebase again after #23883 lands.
