Bug 1745613 - Change nsID::GenerateUUID() to not use NSS's RNG off the main thread. r?keeler
48 bytes, text/x-phabricator-request
Details | Review

https://hg.mozilla.org/integration/autoland/rev/a1b5d8bd40fc added a new nsID::GenerateUUID() factory function that calls NSS_IsInitialized() to check whether NSS has been initialized. If NSS has been initialized, nsID::GenerateUUID() generates a uses NSS's RNG; if NSS hasn't been initialized, nsID::GenerateUUID() falls back to MFBT's RNG.

The tsan error is that nsID::GenerateUUID() is calling NSS_IsInitialized(), which reads global flag nssIsInitted without acquiring the nssInitLock lock.

I think this data race is harmless because (AFAIK) nsID::GenerateUUID() will never nssIsInitted == PR_TRUE before NSS is initialized. nsID::GenerateUUID() might read stale data and think nssIsInitted == PR_FALSE even though it's PR_TRUE, but that should be harmless because nsID::GenerateUUID() will just use MFBT's RNG when it could have used NSS's now-initialized RNG.

https://searchfox.org/mozilla-central/rev/77efe87174ee82dad43da56d71a717139b9f19ee/security/manager/ssl/nsNSSComponent.cpp#105

Some options:

  1. Make NSS_IsInitialized() acquire the nssInitLock lock, though changing NSS's initialization and locking scares me.
  2. Make nsID::GenerateUUID() always use MFBT's RNG instead of trying to use NSS's RNG, though we'd rather a Mozilla-authored RNG (NSS) instead of an OS RNG (MFBT's).
  3. Make nsID::GenerateUUID() check whether NSS is initalized using some other means, perhaps leveraging something like nsNSSComponent.cpp EnsureNSSInitializedChromeOrContent()?

Summary: ThreadSanitizer: data race /builds/worker/checkouts/gecko/security/nss/lib/nss/nssinit.c:782:22 in nss_Init → Intermittent SUMMARY: ThreadSanitizer: data race /builds/worker/checkouts/gecko/security/nss/lib/nss/nssinit.c:782:22 in nss_Init

I reproduced this tsan failure in 1 out of 10 retriggers of mach try fuzzy --query "test-linux1804-64-tsan-qr/opt-mochitest-a11y-1proc".

Calling NSS_IsInitialized() off the main thread caused intermittent tsan failures because NSS_IsInitialized() reads global variable nssIsInitted without acquiring the nssInitLock lock.

During Firefox startup, about 1000 nsIDs are generated, but only about 10 are generated off the main thread, so this change has very little impact on how often nsID::GenerateUUID() will use NSS's RNG. Of the nsIDs generated on the main thread during startup, about 600 are generated before NSS is initialized (so they use MFBT's RNG) and 400 are generated after NSS is initialized.

After Firefox reaches a steady state, loading a light web page like google.com generates about 300 nsIDs and a heavy web page like cnn.com generates about 2000 nsIDs. All these nsIDs are generated on the main thread using NSS's RNG.
