add prohibit-password as a synonymn for without-password,
since the without-password is causing too many questions. Harden it to ban

Remove pattern length argument from match_pattern_list(), we
only ever use it for strlen(pattern).
Prompted by hanno AT hboeck.de pointing an out-of-bound read
error caused by an incorrect pattern length found using AFL
and his own tools.

rename xrealloc() to xreallocarray() since it follows
that form. ok djm

Two small fixes for sshd -T: ListenAddress'es are added
to a list head so reverse the order when printing them to ensure the
behaviour remains the same, and print StreamLocalBindMask as octal with
leading zero. ok 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)

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@
|
|
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@

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

[dh.c myproposal.h packet.c poly1305.c poly1305.h servconf.c ssh.1]
[ssh.c ssh_config.5 sshd_config.5] Add a new protocol 2 transport
cipher "chacha20-poly1305@openssh.com" that combines Daniel
Bernstein's ChaCha20 stream cipher and Poly1305 MAC to build an
authenticated encryption mode.
Inspired by and similar to Adam Langley's proposal for TLS:
http://tools.ietf.org/html/draft-agl-tls-chacha20poly1305-03
but differs in layout used for the MAC calculation and the use of a
second ChaCha20 instance to separately encrypt packet lengths.
Details are in the PROTOCOL.chacha20poly1305 file.
