Fluxheim 1.3.5 Release Notes

Status

Fluxheim 1.3.5 adds the rustls/AWS-LC FIPS-capable candidate path for source
builds and release evidence.

Highlights

• Added a rustls/AWS-LC FIPS-capable candidate backend through
  tls-rustls-fips.
• Added profile-fips-rustls and profile-iso19790-rustls as narrow
  validation aliases for rustls/AWS-LC FIPS and ISO/IEC 19790 terminology.
• Added tls-rustls-iso19790 as the raw ISO/IEC 19790 terminology alias for
  tls-rustls-fips.
• Refactored rustls TLS setup so normal rustls builds keep the ring provider
  while rustls FIPS candidate builds install/pass
  rustls::crypto::default_fips_provider().
• Added rustls FIPS provider diagnostics to fluxheim crypto and
  fluxheim-config-tester --crypto.
• Added examples/fips-rustls.toml, examples/iso19790-rustls.toml, and
  scripts/validate-fips-rustls.sh.
• Added per-backend release evidence skips, --skip-fips-openssl and
  --skip-fips-rustls, for builders that collect OpenSSL and rustls/AWS-LC
  evidence in different environments.

Compliance Boundary

This release does not claim that Fluxheim is FIPS certified or ISO/IEC 19790
validated. The rustls path is a source-build candidate that can make Fluxheim's
TLS listener use rustls' AWS-LC FIPS provider path and fail closed when
[tls.fips] required = true or [tls.iso19790] required = true is configured.

Operators still need the exact AWS-LC module certificate, Security Policy,
platform match, build procedure, deployment records, and non-TLS crypto
evidence before making regulated claims.

The rustls/AWS-LC FIPS candidate build requires the aws-lc-fips-sys toolchain,
including CMake, Go, and a C compiler.

This path intentionally adds a native C/assembly cryptographic module boundary.
It is not a pure-Rust FIPS claim: operators must collect evidence for the exact
validated AWS-LC module, toolchain, platform, and module Security Policy.
Fluxheim fails closed if a FIPS/ISO-required rustls listener cannot report
rustls FIPS mode; the vendored Pingora listener keeps a final panic assertion
with structured context after Fluxheim's normal provider and TLS-policy checks.

Example

cargo build --release --no-default-features --features profile-fips-rustls
scripts/validate-fips-rustls.sh check

Use profile-iso19790-rustls when the operator-facing evidence should use
ISO/IEC 19790 terminology. It maps to the same rustls/AWS-LC FIPS candidate
logic.

For release-mode evidence, use an AWS-LC-supported FIPS builder. Newer rolling
distribution compilers can fail inside aws-lc-fips-sys; the validation helper
now fails early for known newer GCC/Clang families unless
FLUXHEIM_ALLOW_EXPERIMENTAL_AWS_LC_FIPS_TOOLCHAIN=1 is set for investigation
builds.
