Subject: [PATCH] kprobes: Replace HTTP links with HTTPS ones
Date:   Thu,  9 Jul 2020 21:16:36 +0200
Message-Id: <20200709191636.26252-1-grandmaster@al2klimov.de>
In-Reply-To: <20200708184201.611d929ae6017c87ea98b114@kernel.org>
References: <20200708184201.611d929ae6017c87ea98b114@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
          If both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.

 I'd really would like to get HTTPSifying done before other tasks...
