Apparently a prehistoric server implementation would send a certificate_authorities field
that didn't include the outer DER SEQUENCE tag, so PSM attempted to detect this and
work around it.
This prehistoric server implementation isn't in use anywhere anymore, so this 18-yo
server bug workaround can be removed.
This creates a number of stubs and leaves some surrounding code that may be irrelevant (eg. recorded time stamps, status variables).
Stub resolution/removal should be a follow-up to this.
- Added HACL*Poly1305 32-bit (INRIA/Microsoft)
- Updated to final TLS 1.3 draft version (28)
- Removed TLS 1.3 prerelease draft limit check
- Removed NPN code
- Enabled dev/urandom-only RNG on Linux with NSS_SEED_ONLY_DEV_URANDOM for non-standard environments
- Fixed several bugs with TLS 1.3 negotiation
- Updated internal certificate store
- Added support for the TLS Record Size Limit Extension.
- Fixed CVE-2018-0495
- Various security fixes in the ASN.1 code.
- Adds CipherSuite string with the full suite
- Changes CipherName to be the actual cipher name instead of the (erroneous) full suite like Firefox does.
Previous behavior: if an entry was in the previously-used list, and there would be an error connecting to or processing the host, it would adopt it using the previous status, with a new minimum required max age TTL.
New behavior: if an entry is in the previously-used list, and there is an error connecting to or processing the host, it will be dropped from the preload list.
The old behavior would allow entries to persist on the HSTS preload list when they drop off the 'net. Considering domain churn, it would cause issues for new owners for having a persisted HSTS entry preloaded in the browser.
Bonus: it keeps our HSTS preload list lean.
