FAILED: patch "[PATCH] random: quiet urandom warning ratelimit suppression message" failed to apply to 4.19-stable tree

Donenfeld" <Jason(a)zx2c4.com> Date: Thu, 16 Jun 2022 15:00:51 +0200 Subject: [PATCH] random: quiet urandom warning ratelimit suppression message random.c ratelimits how much it warns about uninitialized urandom reads using __ratelimit(). When the RNG is finally initialized, it prints the number of missed messages due to ratelimiting. It has been this way since that functionality was introduced back in 2018. Recently, cc1e127bfa95 ("random: remove ratelimiting for in-kernel unseeded randomness") put a bit more stress on the urandom ratelimiting, which teased out a bug in the implementation. Specifically, when under pressure, __ratelimit() will print its own message and reset the count back to 0, making the final message at the end less useful. Secondly, it does so as a pr_warn(), which apparently is undesirable for people's CI. Fortunately, __ratelimit() has the RATELIMIT_MSG_ON_RELEASE flag exactly for this purpose, so we set the flag.
