Refactor hostkeys_foreach() and dependent code Deal with
IP addresses (i.e. CheckHostIP) Don't clobber known_hosts when nothing
changed ok markus@ as part of larger commit
|
|
permit KRLs that revoke certificates by serial number or
key ID without scoping to a particular CA; ok markus@
|
|
missing parentheses after if in do_convert_from() broke
private key conversion from other formats some time in 2010; bz#2345 reported
by jjelen AT redhat.com
|
|
update to new API (key_fingerprint => sshkey_fingerprint)
check sshkey_fingerprint return values; ok markus
|
|
djm, your /usr/include tree is old
|
|
some feedback from markus@: comment hostkeys_foreach()
context and avoid a member in it.
|
|
make ssh-keygen use hostkeys_foreach(). Removes some
horrendous code; ok markus@
|
|
infer key length correctly when user specified a fully-
qualified key name instead of using the -b bits option; ok markus@
|
|
regression: incorrect error message on
otherwise-successful ssh-keygen -A. Reported by Dmitry Orlov, via deraadt@
|
|
Replace <sys/param.h> with <limits.h> and other less
dirty headers where possible. Annotate <sys/param.h> lines with their
current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1,
LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of
MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution.
These are the files confirmed through binary verification. ok guenther,
millert, doug (helped with the verification protocol)
|
|
sync ssh-keysign, ssh-keygen and some dependencies to the
new buffer/key API; mostly mechanical, ok markus@
|
|
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.
|
|
Add FingerprintHash option to control algorithm used for
key fingerprints. Default changes from MD5 to SHA256 and format from hex to
base64.

[ssh-keygen.c]
When hashing or removing hosts using ssh-keygen, don't choke on
@revoked markers and don't remove @cert-authority markers;
bz#2241, reported by mlindgren AT runelind.net

[gss-serv.c session.c ssh-keygen.c]
standardise on NI_MAXHOST for gethostname() string lengths; about
1/2 the cases were using it already. Fixes bz#2239 en passant

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.

Improve usage() and documentation towards the standard form.
In particular, this line saves a lot of man page reading time.

things for us on error; most things do, but it's unsafe form.

[ssh-keygen.c]
remove duplicated character ('g') in getopt() string;
document the (few) remaining option characters so we don't have to
rummage next time.

unnecessary arc4random_stir() calls. The only ones left are to ensure
that the PRNG gets a different state after fork() for platforms that
have broken the API.
|

[ssh-keygen.c]
Make code match documentation: relative-specified certificate expiry time
should be relative to current time and not the validity start time.
Reported by Petr Lautrbach; ok deraadt@
|
|
[ssh-keygen.c sshconnect1.c sshd.c]
All the instances of arc4random_stir() are bogus, since arc4random()
does this itself, inside itself, and has for a very long time.. Actually,
this was probably reducing the entropy available.
ok djm
ID SYNC ONLY for portable; we don't trust other arc4random implementations
to do this right.

[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.
