Klimov" Subject: [PATCH for v5.9] netfilter: xtables: Replace HTTP links with HTTPS ones Date: Sun, 19 Jul 2020 14:02:12 +0200 Message-Id: <20200719120212.58514-1-grandmaster@al2klimov.de> MIME-Version: 1.0 X-Spamd-Bar: +++++ X-Spam-Level: ***** Authentication-Results: smtp.al2klimov.de; auth=pass smtp.auth=aklimov@al2klimov.de smtp.mailfrom=grandmaster@al2klimov.de Sender: netdev-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: netdev@vger.kernel.org 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 neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

Klimov ' v5.7..master (Actually letting a shell for loop submit all this stuff for me.) If there are any URLs to be removed completely or at least not (just) HTTPSified: Just clearly say so and I'll *undo my change*. See also: https://lkml.org/lkml/2020/6/27/64 If there are any valid, but yet not changed URLs: See: https://lkml.org/lkml/2020/6/26/837 If you apply the patch, please let me know. Sorry again to all maintainers who complained about subject lines. Now I realized that you want an actually perfect prefixes, not just subsystem ones. I tried my best... And yes, *I could* (at least half-)automate it.
