2019-07-05upstream: When system calls indicate an error they return -1, notderaadt@openbsd.org
some arbitrary value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future. OpenBSD-Commit-ID: 48081f00db7518e3b712a49dca06efc2a5428075
2019-06-21upstream: Add protection for private keys at rest in RAM againstdjm@openbsd.org
speculation and memory sidechannel attacks like Spectre, Meltdown, Rowhammer and Rambleed. This change encrypts private keys when they are not in use with a symmetic key that is derived from a relatively large "prekey" consisting of random data (currently 16KB). Attackers must recover the entire prekey with high accuracy before they can attempt to decrypt the shielded private key, but the current generation of attacks have bit error rates that, when applied cumulatively to the entire prekey, make this unlikely. Implementation-wise, keys are encrypted "shielded" when loaded and then automatically and transparently unshielded when used for signatures or when being saved/serialised. Hopefully we can remove this in a few years time when computer architecture has become less unsafe. been in snaps for a bit already; thanks deraadt@ ok dtucker@ deraadt@ OpenBSD-Commit-ID: 19767213c312e46f94b303a512ef8e9218a39bd4
