From ef430522256013665205cdda05636846cc622251 Mon Sep 17 00:00:00 2001 From: Guilhem Moulin Date: Tue, 12 Jul 2016 03:10:33 +0200 Subject: nginx: Don't hard-code the HPKP headers. Instead, lookup the pubkeys and compute the digests on the fly. But never modify the actual header snippet to avoid locking our users out. --- roles/webmail/files/etc/nginx/sites-available/roundcube | 6 +++--- roles/webmail/tasks/roundcube.yml | 13 ++++++++++++- .../etc/nginx/snippets/mail.fripost.org.hpkp-hdr.j2 | 1 + 3 files changed, 16 insertions(+), 4 deletions(-) create mode 120000 roles/webmail/templates/etc/nginx/snippets/mail.fripost.org.hpkp-hdr.j2 (limited to 'roles/webmail') diff --git a/roles/webmail/files/etc/nginx/sites-available/roundcube b/roles/webmail/files/etc/nginx/sites-available/roundcube index 67851ae..c691d35 100644 --- a/roles/webmail/files/etc/nginx/sites-available/roundcube +++ b/roles/webmail/files/etc/nginx/sites-available/roundcube @@ -31,9 +31,9 @@ server { "default-src 'none'; child-src 'self'; frame-src 'self'; connect-src 'self'; object-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline'; img-src * data:; font-src 'self'; reflected-xss block; referrer no-referrer-when-downgrade; frame-ancestors 'self'; form-action 'self'; base-uri mail.fripost.org webmail.fripost.org"; include snippets/ssl.conf; - ssl_certificate /etc/nginx/ssl/mail.fripost.org.pem; - ssl_certificate_key /etc/nginx/ssl/mail.fripost.org.key; - add_header Public-Key-Pins 'pin-sha256="SHfniMEapxeYo5YT/2jP+n+WstNaYghDMhZUadLlPDk="; pin-sha256="/Tt92H3ZkfEW1/AOCoGVm1TxZl7u4c+tIBnuvAc7d5w="; max-age=15778800'; + ssl_certificate ssl/mail.fripost.org.pem; + ssl_certificate_key ssl/mail.fripost.org.key; + include snippets/mail.fripost.org.hpkp-hdr; location = /favicon.ico { root /usr/share/roundcube/skins/default/images; diff --git a/roles/webmail/tasks/roundcube.yml b/roles/webmail/tasks/roundcube.yml index caa91dc..15544c2 100644 --- a/roles/webmail/tasks/roundcube.yml +++ b/roles/webmail/tasks/roundcube.yml @@ -131,9 +131,20 @@ notify: - Restart Nginx +- name: Copy HPKP header snippet + # never modify the pined pubkeys as we don't want to lock out our users + template: src=etc/nginx/snippets/mail.fripost.org.hpkp-hdr.j2 + dest=/etc/nginx/snippets/mail.fripost.org.hpkp-hdr + validate=/bin/false + owner=root group=root + mode=0644 + register: r3 + notify: + - Restart Nginx + - name: Start Nginx service: name=nginx state=started - when: not (r1.changed or r2.changed) + when: not (r1.changed or r2.changed or r3.changed) - meta: flush_handlers diff --git a/roles/webmail/templates/etc/nginx/snippets/mail.fripost.org.hpkp-hdr.j2 b/roles/webmail/templates/etc/nginx/snippets/mail.fripost.org.hpkp-hdr.j2 new file mode 120000 index 0000000..a8ba598 --- /dev/null +++ b/roles/webmail/templates/etc/nginx/snippets/mail.fripost.org.hpkp-hdr.j2 @@ -0,0 +1 @@ +../../../../../../certs/hpkp-hdr.j2 \ No newline at end of file -- cgit v1.2.3
