fix some regressions caused by upstream merges
enable KRLs now that they no longer require BIGNUMs
|
|
Disables and removes dependency on OpenSSL. Many features don't
work and the set of crypto options is greatly restricted. This
will only work on system with native arc4random or /dev/urandom.
Considered highly experimental for now.

avoid BIGNUM in KRL code by using a simple bitmap;
feedback and ok markus

sync changes from libopenssh; prepared by markus@ mostly
debug output tweaks, a couple of error return value changes and some other
minor stuff

missing error assigment on sshbuf_put_string()

free->sshkey_free; ok djm@

deprecate key_load_private_pem() and
sshkey_load_private_pem() interfaces. Refactor the generic key loading API to
not require pathnames to be specified (they weren't really used).
Fixes a few other things en passant:
Makes ed25519 keys work for hostbased authentication (ssh-keysign
previously used the PEM-only routines).
Fixes key comment regression bz#2306: key pathnames were being lost as
comment fields.

Add FingerprintHash option to control algorithm used for
key fingerprints. Default changes from MD5 to SHA256 and format from hex to
base64.

convert KRL code to new buffer API

fix NULL pointer dereference crash on invalid timestamp
found using Michal Zalewski's afl fuzzer

fix KRL generation when multiple CAs are in use
We would generate an invalid KRL when revoking certs by serial
number for multiple CA keys due to a section being written out
twice.
Also extend the regress test to catch this case by having it
produce a multi-CA KRL.

New key API: refactor key-related functions to be more library-like,
existing API is offered as a set of wrappers.

Thanks also to Ben Hawkes, David Tomaschik, Ivan Fratric, Matthew
Dempsky and Ron Bowes for a detailed review a few months ago.
NB. This commit also removes portable OpenSSH support for OpenSSL
<0.9.8e.

[krl.c]
fix bug in KRL generation: multiple consecutive revoked certificate
serial number ranges could be serialised to an invalid format.
Readers of a broken KRL caused by this bug will fail closed, so no
should-have-been-revoked key will be accepted.

[krl.c krl.h PROTOCOL.krl]
add support for Key Revocation Lists (KRLs). These are a compact way to
represent lists of revoked keys and certificates, taking as little as
a single bit of incremental cost to revoke a certificate by serial number.
KRLs are loaded via the existing RevokedKeys sshd_config option.
