sync changes from libopenssh; prepared by markus@ mostly
debug output tweaks, a couple of error return value changes and some other
minor stuff
|
|
Allows disabling support for SSH protocol 1.
|
|
add sshd_config HostbasedAcceptedKeyTypes and
PubkeyAcceptedKeyTypes options to allow sshd to control what public key types
will be accepted. Currently defaults to all. Feedback & ok markus@

missing error assigment on sshbuf_put_string()
|
|
apparently memcpy(x, NULL, 0) is undefined behaviour
according to C99 (cf. sections 7.21.1 and 7.1.4), so check skip memcpy calls
when length==0; ok markus@

free->sshkey_free; ok djm@

allow WITH_OPENSSL w/o WITH_SSH1; ok djm@
|
|
adjust for sshkey_load_file() API change
|
|
fix ssh_config FingerprintHash evaluation order; from Petr
Lautrbach
|
|
reorder hostbased key attempts to better match the
default hostkey algorithms order in myproposal.h; ok markus@
|
|
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.

workaround for the Meyer, et al, Bleichenbacher Side
Channel Attack. fake up a bignum key before RSA decryption. discussed/ok djm

KNF and add a little more debug()
|
|
add fingerprinthash to the options list;
|
|
tweak previous;
|
|
If an invalid rdclass was passed to getrrsetbyname() then
this would execute a free on an uninitialised pointer.
OpenSSH only ever calls this with a fixed and valid rdclass.

Includes fix for 1 byte output overflow for large key length
requests (not reachable in OpenSSH).

patch from writeonce AT midipix.org via bz#2296

|
|

mention ssh -Q feature to list supported { MAC, cipher,
KEX, key } algorithms in more places and include the query string used to
list the relevant information; bz#2288
|

tweak previous;
|
|
regression test for multiple required pubkey authentication;
ok markus@
|
|
correct description of what will happen when a
AuthorizedKeysCommand is specified but AuthorizedKeysCommandUser is not (sshd
will refuse to start)
|
|
make internal handling of filename arguments of "none"
more consistent with ssh. "none" arguments are now replaced with NULL when
the configuration is finalised.
Simplifies checking later on (just need to test not-NULL rather than
that + strcmp) and cleans up some inconsistencies. ok markus@
|
|
remember which public keys have been used for
authentication and refuse to accept previously-used keys.
This allows AuthenticationMethods=publickey,publickey to require
that users authenticate using two _different_ pubkeys.
ok markus@
|
|
fix passing of wildcard forward bind addresses when
connection multiplexing is in use; patch from Sami Hartikainen via bz#2324;
ok dtucker@
|
|
make this slightly easier to diff against portable
|
|
|
|
adjust for new SHA256 key fingerprints and
slightly-different MD5 hex fingerprint format
|
|
poll changes to netcat (usr.bin/netcat.c r1.125) broke
this test; fix it by ensuring more stdio fds are sent to devnull
|
|
tweak previous;
|
|
document FingerprintHash here too
|
|
|
|
Add FingerprintHash option to control algorithm used for
key fingerprints. Default changes from MD5 to SHA256 and format from hex to
base64.

revision 1.2
date: 2014/12/08 03:45:00; author: bcook; state: Exp; lines: +2 -2; commitid: 7zWEBgJJOCZ2hvTV;
avoid left shift overflow in reallocarray.
Some 64-bit platforms (e.g. Windows 64) have a 32-bit long. So, shifting
1UL 32-bits to the left causes an overflow. This replaces the constant 1UL with
(size_t)1 so that we get the correct constant size for the platform.
discussed with tedu@ & deraadt@

explicitly include sys/param.h in files that use the
howmany() macro; from portable

mention AuthorizedKeysCommandUser must be set for
AuthorizedKeysCommand to be run; bz#2287

show in debug output which hostkeys are being tried when
attempting hostbased auth; patch from Iain Morgan

Make manual reflect reality: sftp-server's -d option
accepts a "%d" option, not a "%h" one.

better error value for invalid signature length

unused code. Should fix compile error reported by plautrba at redhat.

add tests for new client RevokedHostKeys option; refactor
to make it a bit more readable

Nuke yet more obvious #include duplications.

key_in_file() wrapper is no longer used

|
add RevokedHostKeys option for the client
Allow textfile or KRL-based revocation of hostkeys.
