Dear developers, please check bugzilla ticket https://bugzilla.kernel.org/show_bug.cgi?id=80981 (not the initial issue, but starting with comment#3.
Reading from /dev/urandom gives EOF after 33554431 bytes. I believe it is introduced by commit 79a8468747c5f95ed3d5ce8376a3e82e0c5857fc, with the chunk nbytes = min_t(size_t, nbytes, INT_MAX >> (ENTROPY_SHIFT + 3)); which is described in commit message as "additional paranoia check to prevent overly large count values to be passed into urandom_read()". I don't know why people pull such large amounts of data from urandom, but given today there are two bugreports regarding problems doing that, i consider that this is practiced. -- Andrey Utkin -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
