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

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

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

96
** mandos-ctl now has a --debug option to show D-Bus calls.
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

180
Version 1.7.13 (2016-10-08)
182
** Minor bug fix: Don't ask for passphrase or fail when generating
183
keys using GnuPG 2.1 in a chrooted environment.
185
Version 1.7.12 (2016-10-05)
187
** Bug fix: Don't crash after exit() when using DH parameters file

248
would otherwise generate a spurious runtime warning.
250

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
** Bug fix: Fix --servicename option, broken since 1.6.4.

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
** Add systemd support.
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

341
** PID file moved from /var/run to /run.
342
** Bug fix: Handle long secrets when saving client state.

372
** Takes new --foreground option
373
** Init script supports new "status" action.
375
** Now uses all interfaces by default; the --interface option can
376
still be used to restrict it, and the argument to --interface (as
377

378
now a comma-separated list of interfaces to use.
380

403
Version 1.5.2 (2012-01-08)
405
** Removed D-Bus signal se.recompile.Mandos.NewRequest() added in
406
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.
421
** Persistent state. Client state is now saved between server
423
** clients.conf file can now contain "enabled" setting for clients.
424
** Bug fix: Fix rare crash bug.
425
** Bug fix: Send corrent D-Bus type in PropertyChanged for
426
"ApprovalDelay", "ApprovalDuration", "Timeout", and
428
** mandos-ctl: Bare numbers as arguments are taken to be milliseconds.
429
** Bug fix: mandos-ctl --secret option now works.
430
** New D-Bus signal: se.recompile.Mandos.NewRequest(s).
432
Version 1.4.1 (2011-10-15)
434
** Make D-Bus properties settable again, and handle checkers
435
for disabled clients correctly.
436
* Miscellaneous fixes to "pedantic" Lintian warnings
438
Version 1.4.0 (2011-10-09)
439

441
** Fixed warning about "rmdir: Directory not empty".
443
** Default values changed: timeout 5 minutes, interval 2 minutes.
444
** Clients gets an expiration extension when receiving a password,
445
controlled by new "extended_timeout" setting.
446
** New domain name: "fukt.bsnet.se" changes to "recompile.se". This
447
also affects the D-Bus bus and interface names (old names still
448
work). Users should start using the new names immediately.
449
** New D-Bus Client object properties "Expires" and "ExtendedTimeout";
450
see DBUS-API for details.
452
Version 1.3.1 (2011-07-27)

480
** New "plymouth" plugin to ask for a password using the Plymouth
481
graphical boot system.
482
** The Mandos client now automatically chooses a network interface if
483
the DEVICE setting in /etc/initramfs-tools/initramfs.conf is set to
484
the empty string. This is also the new default instead of "eth0".
485
** The Mandos client --connect option now loops indefinitely until a
486
password is received from the specified server.
487
** Bug fix: Quote directory correctly in mandos-keygen with --password
488
** Bug fix: don't use "echo -e" in mandos-keygen; unsupported by dash.
490

491
"valid" or "invalid".
492
** New D-Bus API; see the file "DBUS-API".
493

516
** Bug fix: Allow network interface renaming by "udev" by taking down
517
the network interface after using it.
518
** Bug fix: User-supplied plugins are now installed correctly.
519
** Bug fix: If usplash was used but the password was instead provided
520
by the Mandos server, the usplash daemon used to ignore the first
521
command passed to it. This has been fixed.
522
** Bug fix: Make the "--userid" and "--groupid" options in
523
"plugin-runner.conf" work.
525

532
** Bug fix: Use "pkg-config" instead of old "libgnutls-config".
534

541
** Security bug fix: Fix permissions on initrd.img file when
542
installing new linux-image-* packages calling mkinitramfs-kpkg (all
543
version lower than 2.6.28-1-* does this).

Version 1.0.8 (2009-02-25)
547
** Bug fix: Fix missing quote characters in initramfs-tools-hook.
