* feat(proxy): hash UI passwords with PBKDF2 in FIPS mode A FIPS OpenSSL refuses scrypt, so every password write fails there and nobody can sign in with a password. When OpenSSL enforces FIPS, passwords now use PBKDF2-HMAC-SHA256 at 600k iterations with a salt from OpenSSL's DRBG, stored as "pbkdf2:" plus base64 of salt and key. Any other row is refused with one error log and left as it is, and the boot migration does nothing, because FIPS mode is for new deployments. PBKDF2 at 600k takes about five times as long as scrypt, so in FIPS mode the five request paths run it on one thread instead of the event loop. A single thread keeps a login burst from using up a CPU quota, which is what stalls the loop with asyncio.to_thread. A login that queued for that thread asks the throttle again before it answers, so a burst of guesses can't get past a block that the failures ahead of it just set. The breached password check is off in FIPS mode, because it runs the password through SHA-1. A standard OpenSSL reads False at every new branch, so standard mode keeps scrypt, inline, on the same rows. Resolves LIT-8425 * fix(proxy): take FIPS logins one at a time and recheck the throttle first A login that waited for the KDF thread asked the throttle again only after deriving, so a burst for one user kept that thread busy long after the user was blocked. Logins now wait for their turn on a lock and ask the throttle when it comes, so a blocked login costs no PBKDF2 and only one login at a time holds a place in the KDF queue. Password changes and invite claims no longer wait behind a whole burst of logins. * fix(proxy): keep PBKDF2 rows on a standard boot and warn when FIPS skips the breach check A standard boot treated a pbkdf2: row as plaintext and hashed its text, so the real password stopped working and the old row text signed in. The migration now leaves a row of that exact shape alone. Any other pbkdf2: text still migrates. FIPS mode now logs a warning when it skips a breach check that is turned on. The one-thread test no longer depends on timing, and the new test variables are annotated Final. * fix(proxy): keep the breached password check on in FIPS mode * fix(proxy): choose the password KDF from fips_mode instead of the host OpenSSL * test(proxy): fake the scrypt probe in the FIPS fixture now that the gate checks scrypt |
