| * lockup-watchdogs.txt: standardize document formatMauro Carvalho Chehab2017-07-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Each text file under Documentation follows a different format. Some doesn't even have titles! Change its representation to follow the adopted standard, using ReST markups for it to be parseable by Sphinx. This file is almost at ReST format. Just one title needs to be adjusted, in order to follow the standard. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

Also print a warning if get_random_*() is called before the CRNG is initialized. By default, only one single-line warning will be printed per boot. If CONFIG_WARN_ALL_UNSEEDED_RANDOM is defined, then a warning will be printed for each function which tries to get random bytes before the CRNG is initialized. This can get spammy for certain architecture types, so it is not enabled by default" * tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random: random: reorder READ_ONCE() in get_random_uXX random: suppress spammy warnings about unseeded randomness random: warn when kernel uses unseeded randomness net/route: use get_random_int for random counter net/neighbor: use get_random_u32 for 32-bit hash random rhashtable: use get_random_u32 for hash_rnd ceph: ensure RNG is seeded before using iscsi: ensure RNG is seeded before use cifs: use get_random_u32 for 32-bit lock random random: add get_random_{bytes,u32,u64,int,long,once}_wait family random: add wait_for_random_bytes() API

| * | random: suppress spammy warnings about unseeded randomnessTheodore Ts'o2017-07-152-23/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, on some models of some architectures getting a fully seeded CRNG is extremely difficult, and so this can result in dmesg getting spammed for a surprisingly long time. This is really bad from a security perspective, and so architecture maintainers really need to do what they can to get the CRNG seeded sooner after the system is booted. However, users can't do anything actionble to address this, and spamming the kernel messages log will only just annoy people. For developers who want to work on improving this situation, CONFIG_WARN_UNSEEDED_RANDOM has been renamed to CONFIG_WARN_ALL_UNSEEDED_RANDOM. By default the kernel will always print the first use of unseeded randomness. This way, hopefully the security obsessed will be happy that there is _some_ indication when the kernel boots there may be a potential issue with that architecture or subarchitecture. To see all uses of unseeded randomness, developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM. Signed-off-by: Theodore Ts'o <tytso@mit.edu>
| * | random: warn when kernel uses unseeded randomnessJason A. Donenfeld2017-06-202-2/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enables an important dmesg notification about when drivers have used the crng without it being seeded first. Prior, these errors would occur silently, and so there hasn't been a great way of diagnosing these types of bugs for obscure setups. By adding this as a config option, we can leave it on by default, so that we learn where these issues happen, in the field, will still allowing some people to turn it off, if they really know what they're doing and do not want the log entries. However, we don't leave it _completely_ by default. An earlier version of this patch simply had `default y`. I'd really love that, but it turns out, this problem with unseeded randomness being used is really quite present and is going to take a long time to fix. Thus, as a compromise between log-messages-for-all and nobody-knows, this is `default y`, except it is also `depends on DEBUG_KERNEL`. This will ensure that the curious see the messages while others don't have to. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
| * | net/route: use get_random_int for random counterJason A. Donenfeld2017-06-201-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using get_random_int here is faster, more fitting of the use case, and just as cryptographically secure. It also has the benefit of providing better randomness at early boot, which is when many of these structures are assigned. Also, semantically, it's not really proper to have been assigning an atomic_t in this way before, even if in practice it works fine. Signed-off-by: Jason A.
