> Quick question: is pkcs11.txt a default filename used anywhere else? Where did the filename come from?
¯\_(ツ)_/¯ There is a lot (a lot) of history here, buried deep somewhere in the internet... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to nss in Ubuntu. https://bugs.launchpad.net/bugs/2016303 Title: Rebuild NSS with support for system-wide config file Status in nss package in Ubuntu: Confirmed Bug description: NSS should be rebuilt with this patch: diff --git a/debian/libnss3.dirs b/debian/libnss3.dirs new file mode 100644 index 00000000..0f796964 --- /dev/null +++ b/debian/libnss3.dirs @@ -0,0 +1 @@ +etc/nss diff --git a/debian/rules b/debian/rules index 5ab1ced0..51bee160 100755 --- a/debian/rules +++ b/debian/rules @@ -128,6 +128,8 @@ override_dh_auto_build: NSS_USE_SYSTEM_SQLITE=1 \ NSS_ENABLE_ECC=1 \ CHECKLOC= \ + POLICY_FILE=pkcs11.txt \ + POLICY_PATH=/etc/nss \ $(TOOLCHAIN) override_dh_auto_clean: The directory could be another one, of course. This will allow us to create a system-wide /etc/nss/pkcs11.txt file which could load the NSS policy module. The upstream documentation is quite poor and outdated, unfortunately: https://firefox-source-docs.mozilla.org/security/nss/legacy/nss_config_options/ https://firefox-source-docs.mozilla.org/security/nss/legacy/pkcs11/module_specs/index.html The current source code is the best documentation, and has a ton of tests that show how to use the policy module: - allow/disallow options: https://git.launchpad.net/ubuntu/+source/nss/tree/nss/lib/pk11wrap/pk11pars.c#n144 - versions and key sizes: https://git.launchpad.net/ubuntu/+source/nss/tree/nss/lib/pk11wrap/pk11pars.c#n437 - other qualifiers for algorithms (which types of signatures): https://git.launchpad.net/ubuntu/+source/nss/tree/nss/lib/pk11wrap/pk11pars.c#n451 - tons of policy tests: https://git.launchpad.net/ubuntu/+source/nss/tree/nss/tests/ssl/sslpolicy.txt and https://git.launchpad.net/ubuntu/+source/nss/tree/nss/tests/policy Here is a sample /etc/nss/pkcs11.txt which enables the policy module with certain values: library= name=Policy NSS=flags=policyOnly,moduleDB config="disallow=ALL allow=HMAC-SHA256:HMAC-SHA1:HMAC-SHA384:HMAC-SHA512:CURVE25519:SECP256R1:SECP384R1:SECP521R1:aes256-gcm:chacha20-poly1305:aes256-cbc:aes128-gcm:aes128-cbc:SHA256:SHA384:SHA512:SHA224:ECDHE-RSA:ECDHE-ECDSA:RSA:DHE-RSA:ECDSA:RSA-PSS:RSA-PKCS:tls-version-min=tls1.2:dtls-version-min=dtls1.2:DH-MIN=2048:DSA-MIN=2048:RSA-MIN=2048" The same config snippet can of course be used in ~/.pki/nssdb/pkcs11.txt or in any of the other many places we have a pkcs11.txt file on the system (hence the need for this build option: to have just one place): - firefox: ~/snap/firefox/common/.mozilla/firefox/pqx65eu1.default/pkcs11.txt - thunderbid: ~/.thunderbird/6mxs87xg.default-release/pkcs11.txt - chrome and system-provided libnss3: ~/.pki/nssdb/pkcs11.txt Note thunderbird ships its own libnss3 (zomg), and would not be affected by this build change (unless it's done in the thunderbird source package too).
