[PATCH 1/2] random: only read from /dev/random after its pool has received 128 bits
by Yang Yingliang 15 Sep '20

15 Sep '20

From: Theodore Ts'o <tytso(a)mit.edu> mainline inclusion from mainline-v5.2-rc1 commit eb9d1bf079bb438d1a066d72337092935fc770f6 category: bugfix bugzilla: NA CVE: NA https://gitee.com/openeuler/kernel/issues/I1CVQ4?from=project-issue ------------------------------------------------- Immediately after boot, we allow reads from /dev/random before its entropy pool has been fully initialized. Fix this so that we don't allow this until the blocking pool has received 128 bits. We do this by repurposing the initialized flag in the entropy pool struct, and use the initialized flag in the blocking pool to indicate whether it is safe to pull from the blocking pool. To do this, we needed to rework when we decide to push entropy from the input pool to the blocking pool, since the initialized flag for the input pool was used for this purpose. To simplify things, we no longer use the initialized flag for that purpose, nor do we use the entropy_total field any more.
