Version 1.8.17 (2024-09-12)
5
* Improve documentation slightly, especially how to add extra options
6
to mandos-client when using dracut with systemd.
7
* Make life easier for distribution packagers by making sure that
8
"make install" creates all required directories.
10
** When seeing clients.conf entries lacking both fingerprint and
11
key_id, show a warning and ignore them instead of crashing,
13
** Suppress most spurious compiler warnings.
15
** In initramfs-tools-hook, be aware of new name of GPGME library,
17
** In password-agent(8mandos), look for a Plymouth process in
18
alphabetical order, not in reverse alphabetical order. This is
19
technically a user-visible change, but should never matter in
22
Version 1.8.16 (2023-02-08)
24
** Bug fix: Start client checkers after a random delay
26
Version 1.8.15 (2022-04-25)
28
** Bug fix: When running "mandos-keygen --password" to read a password
29
interactively (to save in a section in the clients.conf file),
30
backslashes in the password are no longer interpreted as backslash
32
** GnuTLS debug output no longer has a "b'" prefix.
34
Version 1.8.14 (2021-02-03)
36
** Create /dev/fd symlink (if necessary) in plugin-runner(8mandos) and

50
** Fix file descriptor leak when adding or removing local routes to
51
unreachable hosts on the local network.

57
** When using systemd, allow easier modification of server options
58
** Better log messages in mandos-monitor
60

65
Version 1.8.8 (2019-08-18)
66
* No user-visible changes
68
Version 1.8.7 (2019-08-05)
70
** Always compile with LFS (Large File Support) enabled.
72
** Improve intro(8mandos) manual page to cover dracut(8) support.
74
Version 1.8.6 (2019-08-03)
76
** dracut support: In password-agent, properly ignore deleted and
77
renamed question files, and also fix memory alignment issue.
79
Version 1.8.5 (2019-07-30)
81
** Support dracut(8) as well as initramfs-tools(7).
82
** Minor bug fix: Allow the mandos-keygen --passfile option to use
83
passfiles with names starting with "-".
84
** Document known limitation of mandos-keygen --password; it strips
85
white space from start and end of the password.
87
** Bug fix: The server used to fail to restart if the "port" setting
88
was used. This has been fixed.
89

92
Version 1.8.4 (2019-04-09)
94

98
Version 1.8.3 (2019-02-11)
99
* No user-visible changes.
101
Version 1.8.2 (2019-02-10)
103
** In mandos-keygen, ignore failures to remove files in some cases.
105
Version 1.8.1 (2019-02-10)
107
** Only generate TLS keys using GnuTLS' certtool, of sufficient
108
version. Key generation of TLS keys will not happen until a
109
version of GnuTLS is installed with support for raw public keys.
110
** Remove any bad keys created by 1.8.0 and openssl.
112
** On installation, edit clients.conf and remove the same bad key ID
113
which was erroneously reported by all 1.8.0 clients. Also do not
114
trust this key ID in the server.
116
Version 1.8.0 (2019-02-10)
118
** Use new TLS keys for server communication and identification.
119
With GnuTLS 3.6 or later, OpenPGP keys are no longer supported.
120
The client can now use the new "raw public keys" (RFC 7250) API
121
instead, using GnuTLS 3.6.6. Please note: This *requires* new key
122
IDs to be added to server's client.conf file.
123
** New --tls-privkey and --tls-pubkey options to load TLS key files.
124
If GnuTLS is too old, these options do nothing.
126
** Supports either old or new GnuTLS.
127
The server now supports using GnuTLS 3.6.6 and clients connecting
128
with "raw public keys" as identification. The server will read
129
both fingerprints and key IDs from clients.conf file, and will use
130
either one or the other, depending on what is supported by GnuTLS
131
on the system. Please note: both are *not* supported at once; if
132
one type is supported by GnuTLS, all values of the other type from
133
clients.conf are ignored.
135
Version 1.7.20 (2018-08-19)
137
** Fix: Adapt to the Debian cryptsetup package 2.0.3 or later.
138
Important: in that version or later, the plugins "askpass-fifo",
139
"password-prompt", and "plymouth" will no longer be run, since they
140
would conflict with what cryptsetup is doing. Other plugins, such
141
as mandos-client and any user-supplied plugins, will still run.
142
** Better error message if failing to decrypt secret data
143
** Check for (and report) any key import failure from GPGME
144
** Better error message if self-signature verification fails
145
** Set system clock if not set; required by GnuPG for key import
146
** When debugging plugin-runner, it will now show starting plugins
148
Version 1.7.19 (2018-02-22)
150
** Do not print "unlink(...): No such file or directory".
151
** Bug fixes: Fix file descriptor leaks.
152
** Bug fix: Don't use leak sanitizer with leaking libraries.
154
Version 1.7.18 (2018-02-12)

183
keys using GnuPG 2.1 in a chrooted environment.
185

244
Version 1.7.3 (2016-02-29)
246

269
** Bug fix: Be compatible with old 2048-bit DSA keys.
270
** The D-Bus API now provides the standard D-Bus ObjectManager
271
interface, and deprecates older functionality. See the DBUS-API
272
file for the currently recommended API. Note: the original API
273
still works, but is deprecated.
275
** Can now find Mandos server even if the server has an IPv6 address
276
on a network without IPv6 Router Advertisment (like if the Mandos
277
client itself is the router, or there is an IPv6 router advertising
278
a network other than the one which the Mandos server is on.)
279
** Use a better value than 1024 for the default number of DH bits.
280
This better value is either provided by a DH parameters file (see
281
below) or an appropriate number of DH bits is determined based on
283
** Bug fix: mandos-keygen now generates correct output for the
284
"Checker" variable even if the SSH server on the Mandos client has
285
multiple SSH key types.

309
** If client host has an SSH server, "mandos-keygen --password" now
310
outputs "checker" option which uses "ssh-keyscan"; this is more
311
secure than the default "fping" checker.
312
** Bug fix: allow "." in network hook names, to match documentation.
313
** Better error messages.
315
** New --no-zeroconf option.
316

322
** Give better error messages when run without sufficient privileges
323
** Only warn if workaround for Debian bug #633582 was necessary and
324
failed, not if it failed and was unnecessary.
326
Version 1.6.4 (2014-02-16)
328
** Very minor fix to self-test code.
330
Version 1.6.3 (2014-01-21)
332

333
** For PID file, fall back to /var/run if /run does not exist.
335
** Moved files from /usr/lib/mandos to whatever the architecture
336

372
** Takes new --foreground option
373
** Init script supports new "status" action.
375

403
Version 1.5.2 (2012-01-08)
405
** Removed D-Bus signal se.recompile.Mandos.NewRequest() added in

1.5.0. It was buggy and was of questionable utility.
408
Version 1.5.1 (2012-01-01)
410
** Include intro(8mandos) manual page, missing since migration from
411
README file in version 1.4.0.
413
Version 1.5.0 (2012-01-01)
415
** Network hooks. The Mandos client can now run custom scripts to take
416
up a network interface before the client is run. Three example
417
scripts are provided: "wireless", "openvpn", and "bridge".
418
To facilitate this, the client now prefers network interfaces which
419
are up (if any) over all other interfaces.
