sshbuf_dup_string() to replace a common idiom of strdup(sshbuf_ptr()) with
better safety checking; feedback and ok markus@

Add a function to enable security-related malloc_options.
With and ok deraadt@, something similar has been in the snaps for a while.

use SSH_MAX_PUBKEY_BYTES consistently as buffer size when
reading key files. Increase it to match the size of the buffers already being
used.

Support fingerprinting multiple plain keys in a file and authorized_keys
files too (bz#1319)

make ssh-keygen default to ed25519 keys when compiled
without OpenSSL; bz#2388, ok dtucker@

Support "ssh-keygen -lF hostname" to find search known_hosts
and print key hashes. Already advertised by ssh-keygen(1), but not delivered
by code; ok dtucker@
Upstream-ID: 459e0e2bf39825e41b0811c336db2d56a1c23387
|
|
fix compilation with OPENSSL=no; ok dtucker@
|
|
rename xrealloc() to xreallocarray() since it follows
that form. ok djm
|
|
use error/logit/fatal instead of fprintf(stderr, ...)
and exit(0), fix a few errors that were being printed to stdout instead of
stderr and a few non-errors that were going to stderr instead of stdout
bz#2325; ok dtucker
|
|
Comments are only supported for RSA1 keys. If a user
tried to add one and entered his passphrase, explicitly clear it before exit.
This is done in all other error paths, too.
ok djm

for ssh-keygen -A, don't try (and fail) to generate ssh
v.1 keys when compiled without SSH1 support RSA/DSA/ECDSA keys when compiled
without OpenSSL based on patch by Mike Frysinger; bz#2369
|
|
don't printf NULL key comments; reported by Tom Christensen
|
|
add -v (show ASCII art) to -l's synopsis; ok djm@
|
|
further silence spurious error message even when -v is
specified (e.g. to get visual host keys); reported by naddy@
|
|
silence a spurious error message when listing
fingerprints for known_hosts; bz#2342
|
|
|
|
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.
Feedback and ok naddy@ markus@

Free resources on error in mkstemp and fdopen

[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

with and ok markus@
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.
