|
* 0.4.0
|
|
|
- Both pam_usb and its tools (adm, hotplug) have been redesigned from the
|
|
|
ground up and rewritten from scratch.
|
|
|
- Hardware recognition is now done through HAL which provides a stable
|
|
|
interface over kernel changes.
|
|
|
- Certificates have been replaced by one time pads. That will prevent
|
|
|
copies of the USB device to be used for authentication.
|
|
|
- Device's manufacturer properties verification. Pamusb now verifies
|
|
|
device informations (vendor, product, serial number, UUID) in the
|
|
|
authentication process.
|
|
|
- Configuration is now handled in a central place, the pusb.conf
|
|
|
configuration file. This XML file contains configuration entries for
|
|
|
users, devices and services.
|
|
|
- pusb_hotplug (formely usbhotplug) make use of DBUS signals (sent by HAL)
|
|
|
instead of kernel hotplugging. Also, its configuration has been merged
|
|
|
into the pusb.conf configuration file.
|
|
|
- A new tool named pusb_check has been added. It can perform authentication
|
|
|
the way the PAM module does. It can be useful for testing and scripting
|
|
|
purposes.
|
|
|
|
|
|
* 0.3.3
|
|
|
- The option keypath is now splitted into local_keypath and device_keypath.
|
|
|
- Fixed a bug that occurred when the TTY entry was empty.
|
|
|
- pam_usb doesn't get anymore the tty name from PAM_TTY as it used to be
|
|
|
empty on some systems.
|
|
|
- Better defaults. The default options have been set to fit most needs,
|
|
|
you are no longer required to use !check_device on 2.6.
|
|
|
- Verbose mode. By default, pam_usb now prints some informations during
|
|
|
the login process (access granted, the reason why access was refused, etc).
|
|
|
This can be turned off using the brand new 'quiet' option.
|
|
|
- Other small fixes.
|
|
|
|
|
|
* 0.3.2
|
|
|
- Now pam_usb will also try to autodetect /dev/sdN devices (not just
|
|
|
/dev/sdNX).
|
|
|
- Fixed a bug that happened when the application using PAM didn't set
|
|
|
PAM_TTY correctly.
|
|
|
- Added the use_first_pass and try_first_pass options.
|
|
|
Now if you enter your password on another PAM module (such as pam_mount
|
|
|
or pam_ssh), pam_usb will use that password to decrypt the private key.
|
|
|
|
|
|
* 0.3.1
|
|
|
- Lot of misc fixes (memory management, Makefiles, sanity checks, etc).
|
|
|
I'd like to thank the PaX Team <pageexec@freemail.hu> who did almost
|
|
|
the whole job.
|
|
|
- Added the hostname option which allows to select what hostname should
|
|
|
be used for authentication (useful for shared public keys over lan).
|
|
|
Thanks to Nicolas Chauvat <chauvat@nerim.net> who reported the issue,
|
|
|
the idea and the patch for this feature.
|
|
|
|
|
|
* 0.3.0
|
|
|
- Not much changes in this version beside a gcc fix, but the 0.2 branch
|
|
|
reached too many new features so i wanted to name this release 0.3.0
|
|
|
as i should have done with 0.2.3
|
|
|
- Fixed a gcc 3.3 compile issue, and all related warning.
|
|
|
I would like to thank the following guys for having reported this bug so fast:
|
|
|
Lalande Fabrice <fabrice.lalande@orange.fr>
|
|
|
Marco <gaedol@softhome.net>
|
|
|
Neil Dunbar <neil.dunbar@hp.com>
|
|
|
|
|
|
* 0.2.3
|
|
|
- Added the usbhotplug tool.
|
|
|
usbhotplug is a hotplug agent that will automagically start a lock handler
|
|
|
when the usb device is removed and an unlock handler when the usb device
|
|
|
is plugged back in and authenticated through pam_usb.
|
|
|
|
|
|
The default handlers will start xlock when the usb device is removed,
|
|
|
and will kill it when the usb device is plugged back in and authenticated.
|
|
|
|
|
|
I'd like to thank Wout Mertens <wmertens@cisco.com> as we had a couple
|
|
|
of discussions about hotplug which helped me implementing this tool.
|
|
|
|
|
|
- The parser can now understand "option" and "!option" instead of
|
|
|
option=1 and option=-1 (e.g. debug !check_device).
|
|
|
Thanks to Jean-Christophe JASKULA <jean.christophe.jasku-la@wanadoo.fr> who
|
|
|
suggested me that and provided an initial patch.
|
|
|
|
|
|
- Fixed a loop bug on serial number checking. Thanks to Zs <horzsol@freemail.hu>
|
|
|
for reporting the bug and a patch to fix it.
|
|
|
|
|
|
- Added the direct_open option which allows to open the private key
|
|
|
using O_DIRECT to avoid disk caching (works only on devices that
|
|
|
supports it). Thanks to myles <myles@tenhand.com> who suggested me that.
|
|
|
|
|
|
- Added some sanity checks here and there because it seems that the PAM
|
|
|
API can return weird stuff from time to time.
|
|
|
|
|
|
- Handling the mount point creation/remotion in a better way which seems
|
|
|
to fix a couple of mntpoint problems.
|
|
|
|
|
|
* 0.2.2
|
|
|
- Added the keep_mounted option, which allows to not umount the mount point
|
|
|
once logged (useful if the gpg/ssh key is stored on there)
|
|
|
|
|
|
- Fixed the mntpoint option: do not delete the directory if it's not a
|
|
|
temporary one.
|
|
|
|
|
|
- Added the support to pass multiple filesystems name with the fs=
|
|
|
option (comma separated list). Changed the default fs to "ext2,vfat"
|
|
|
|
|
|
- Added the log_file option. Takes a filename as a argument.
|
|
|
Combined with debug=1 it can log debug messages to a file.
|
|
|
|
|
|
- Not mounting the device as read-only anymore. Instead, the mount_opts
|
|
|
option has been created. It accepts a comma separated list of mount
|
|
|
options (accepted options are: ro,bind,sync,remount,nosuid,noexec,nodev).
|
|
|
|
|
|
- Fixed an issue which made the allow_remote feature not working correctly
|
|
|
with gdm/kdm.
|
|
|
|
|
|
- Introduced the local_hosts and local_consoles options. They contain a
|
|
|
comma separated lists of hosts and consoles allowed to log in while using
|
|
|
allow_remote=-1
|
|
|
|
|
|
* 0.2.1
|
|
|
- Changed the naming method from x.y to x.y.z
|
|
|
|
|
|
- pam_usb is now able to distinguish local users from remote (as in
|
|
|
logged via ssh), and denies the authentication of non-local users.
|
|
|
Setting allow_remote to 1 disable this feature.
|
|
|
|
|
|
- Mounting is now done in read-only.
|
|
|
|
|
|
- Added the missing mandatory PAM functions.
|
|
|
|
|
|
* 0.2_rc2
|
|
|
- Workaround to make pam_usb not use /proc so it can run on Linux 2.6
|
|
|
By setting check_device to -1, pam_usb will neither check the device's
|
|
|
serial number, nor if it's attached. It's not a real problem if you
|
|
|
don't need serial number checking, but don't combine it with
|
|
|
check_if_mounted.
|
|
|
|
|
|
- Added the force_device capability. Now you can specify a device that
|
|
|
will be mounted without going in guessing mode. If the device cannot
|
|
|
be mounted, it'll switch back to the default guess mode.
|
|
|
Useful if guess mode fails, if you don't want it to try several
|
|
|
devices before getting the right one (so you can login faster), or if
|
|
|
you want to login using a floppy disk, a cdrom or whatever you want.
|
|
|
|
|
|
- Modified the serial number authentication method so now if no serial
|
|
|
numbers are avaible on a device, it will try to use the GUID.
|
|
|
Thanks to Damien Braillard <damien.b@freesurf.ch> who reported the
|
|
|
issue, suggested a way to fix it, and provided a first patch for it.
|
|
|
|
|
|
* 0.2_rc1
|
|
|
- Radically changed the way pam_usb authenticates the user on the
|
|
|
system. Now it works with a pair of DSA keys.
|
|
|
|
|
|
Thanks to Wout Mertens <wmertens@cisco.com> who told me that i could
|
|
|
use a couple of SSH keys to fix the authentication issue.
|
|
|
That gave me the idea to use a set of private/public keys.
|
|
|
|
|
|
Thanks to Ilkka Mattila <ilkka@lyseo.edu.ouka.fi> who helped me to
|
|
|
find out a better way to implement the key challenge: extracting the
|
|
|
public key was inadequate.
|
|
|
|
|
|
Also thanks to those who brought up weird scenarios and/or tested
|
|
|
pre-releases of pam_usb, in alphabetical order:

|
* 0.1:
|
|
|
- Now pam_usb doesn't require a mount point. Instead, it creates
|
|
|
a temporary directory under /tmp.
|
|
|
Thanks to Loic Jaquemet <jaquemet@fiifo.u-psud.fr> who gave me the idea.
|
|
|
|
|
|
- Compiles with gcc 2.95 thanks to Tobias Bayer <tobi.bayer@gmx.de> bug
|
|
|
report.
|
|
|
|
|
|
* 0.1-beta2:
|
|
|
- procfile and device entries autodetection have been fixed thanks to
|
|
|
Thomas Stewart <thomas@stewarts.org.uk> bug reports.
|
|
|
|
|
|
- devfs support added. Thanks to Loic Jaquemet <jaquemet@fiifo.u-psud.fr>
|
|
|
for the bug report.
|
|
|
|
|
|
* 0.1-beta1:
|
|
|
- Initial release
