Modified Files: src/sys/crypto/cprng_fast: cprng_fast.c Log Message: cprng_fast(9): Drop and retake percpu reference across cprng_strong. cprng_strong may sleep on an adaptive lock (via entropy_extract), which invalidates percpu(9) references. Discovered by stumbling upon this panic in a test run: panic: kernel diagnostic assertion "(cprng == percpu_getref(cprng_fast_percpu)) && (percpu_putref(cprng_fast_percpu), true)" failed: file "/home/riastradh/netbsd/current/src/sys/rump/librump/rumpkern/../../../crypto/cprng_fast/cprng_fast.c", line 117 XXX pullup-10 To generate a diff of this commit: cvs rdiff -u -r1.18 -r1.19 src/sys/crypto/cprng_fast/cprng_fast.c Please note that diffs are not public domain; they are subject to the copyright notices on the relevant files.
