When a new request occurs at the end\nof a read operation, that is, when the result of that request is\nonly needed by the next reader, then there is a race between the\nwriting of the new data and the next reader.\n\nThis is because there is no synchronisation whatsoever between the\nwriter and the reader.\n\nFix this by writing data_avail with smp_store_release and reading\nit with smp_load_acquire when we first enter read.  The subsequent\nreads are safe because they're either protected by the first load\nacquire, or by the completion mechanism.\n\nAlso remove the redundant zeroing of data_idx in random_recv_done\n(data_idx must already be zero at this point) and data_avail in\nrequest_entropy (ditto)."}],"metrics":{},"references":[{"url":"https://git.kernel.org/stable/c/22c30022cde6e2c88612b3a499223cfa912f1bc7","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/241ef15776a7c8505008db689175b320d345ecd3","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/2fc91f156b3f3446a1bce80cf4adedcbf41271c2","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/318657b4c2077289659f1cd9e2a34f6a3b208e3e","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/77471e4912d3960dafe141e268c44be8024fe4dc","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/a43bcb0b661cbbf3ad797d2aee6b6fd06b8fc69d","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/ac52578d6e8d300dd50f790f29a24169b1edd26c","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/c76d991b6f01a5d931e7053a73bc9524975a5215","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}]}}]}
