+GigaSet 307x Device Driver
+==========================
+
+1.   Requirements
+     ------------
+1.1. Hardware
+     --------
+     This release supports the connection of the Gigaset 307x/417x family of
+     ISDN DECT bases via Gigaset M101 Data, Gigaset M105 Data or direct USB
+     connection. The following devices are reported to be compatible:
+     307x/417x:
+        Gigaset SX255isdn
+        Gigaset SX353isdn
+        Sinus 45 [AB] isdn (Deutsche Telekom)
+        Sinus 721X/XA
+        Vox Chicago 390 ISDN (KPN Telecom)
+     M101:
+        Sinus 45 Data 1 (Telekom)
+     M105:
+        Gigaset USB Adapter DECT
+        Sinus 45 Data 2 (Telekom)
+        Sinus 721 data
+        Chicago 390 USB (KPN)
+     See also http://www.erbze.info/sinus_gigaset.htm and
+              http://gigaset307x.sourceforge.net/
+
+     We had also reports from users of Gigaset M105 who could use the drivers
+     with SX 100 and CX 100 ISDN bases (only in unimodem mode, see section 2.4.)
+     If you have another device that works with our driver, please let us know.
+     For example, Gigaset SX205isdn/Sinus 721 X SE and Gigaset SX303isdn bases
+     are just versions without answering machine of models known to work, so
+     they should work just as well; but so far we are lacking positive reports
+     on these.
+
+     Chances of getting an USB device to work are good if the output of
+        lsusb
+     at the command line contains one of the following:
+        ID 0681:0001
+        ID 0681:0002
+        ID 0681:0009
+        ID 0681:0021
+        ID 0681:0022
+
+1.2. Software
+     --------
+     The driver works with ISDN4linux and so can be used with any software
+     which is able to use ISDN4linux for ISDN connections (voice or data).
+     CAPI4Linux support is planned but not yet available.
+
+     There are some user space tools available at
+     http://sourceforge.net/projects/gigaset307x/
+     which provide access to additional device specific functions like SMS,
+     phonebook or call journal.
+
+
+2.   How to use the driver
+     ---------------------
+2.1. Modules
+     -------
+     To get the device working, you have to load the proper kernel module. You
+     can do this using
+         modprobe modulename
+     where modulename is usb_gigaset (M105) or bas_gigaset (direct USB
+     connection to the base).
+
+2.2. Device nodes for user space programs
+     ------------------------------------
+     The device can be accessed from user space (eg. by the user space tools
+     mentioned in 1.2.) through the device nodes:
+
+     - /dev/ttyGU0 for M105 (USB data boxes)
+     - /dev/ttyGB0 for the base driver (direct USB connection)
+
+     You can also select a "default device" which is used by the frontends when
+     no device node is given as parameter, by creating a symlink /dev/ttyG to
+     one of them, eg.:
+
+        ln -s /dev/ttyGB0 /dev/ttyG
+
+2.3. ISDN4linux
+     ----------
+     This is the "normal" mode of operation. After loading the module you can
+     set up the ISDN system just as you'd do with any ISDN card.
+     Your distribution should provide some configuration utility.
+     If not, you can use some HOWTOs like
+         http://www.linuxhaven.de/dlhp/HOWTO/DE-ISDN-HOWTO-5.html
+     If this doesn't work, because you have some recent device like SX100 where
+     debug output (see section 3.2.) shows something like this when dialing
+         CMD Received: ERROR
+         Available Params: 0
+         Connection State: 0, Response: -1
+         gigaset_process_response: resp_code -1 in ConState 0 !
+         Timeout occurred
+     you might need to use unimodem mode:
+
+2.4. Unimodem mode
+     -------------
+     This is needed for some devices [e.g. SX100] as they have problems with
+     the "normal" commands.
+
+     If you have installed the command line tool gigacontr, you can enter
+     unimodem mode using
+         gigacontr --mode unimodem
+     You can switch back using
+         gigacontr --mode isdn
+
+     You can also load the driver using e.g.
+         modprobe usb_gigaset startmode=0
+     to prevent the driver from starting in "isdn4linux mode".
+
+     In this mode the device works like a modem connected to a serial port
+     (the /dev/ttyGU0, ... mentioned above) which understands the commands
+         ATZ                 init, reset
+             => OK or ERROR
+         ATD
+         ATDT                dial
+             => OK, CONNECT,
+                BUSY,
+                NO DIAL TONE,
+                NO CARRIER,
+                NO ANSWER
+         <pause>+++<pause>   change to command mode when connected
+         ATH                 hangup
+
+     You can use some configuration tool of your distribution to configure this
+     "modem" or configure pppd/wvdial manually. There are some example ppp
+     configuration files and chat scripts in the gigaset-VERSION/ppp directory.
+     Please note that the USB drivers are not able to change the state of the
+     control lines (the M105 driver can be configured to use some undocumented
+     control requests, if you really need the control lines, though). This means
+     you must use "Stupid Mode" if you are using wvdial or you should use the
+     nocrtscts option of pppd.
+     You must also assure that the ppp_async module is loaded with the parameter
+     flag_time=0. You can do this e.g. by adding a line like
+
+        options ppp_async flag_time=0
+
+     to /etc/modprobe.conf. If your distribution has some local module
+     configuration file like /etc/modprobe.conf.local,
+     using that should be preferred.
+
+2.5. Call-ID (CID) mode
+     ------------------
+     Call-IDs are numbers used to tag commands to, and responses from, the
+     Gigaset base in order to support the simultaneous handling of multiple
+     ISDN calls. Their use can be enabled ("CID mode") or disabled ("Unimodem
+     mode"). Without Call-IDs (in Unimodem mode), only a very limited set of
+     functions is available. It allows outgoing data connections only, but
+     does not signal incoming calls or other base events.
+
+     DECT cordless data devices (M10x) permanently occupy the cordless
+     connection to the base while Call-IDs are activated. As the Gigaset
+     bases only support one DECT data connection at a time, this prevents
+     other DECT cordless data devices from accessing the base.
+
+     During active operation, the driver switches to the necessary mode
+     automatically. However, for the reasons above, the mode chosen when
+     the device is not in use (idle) can be selected by the user.
+     - If you want to receive incoming calls, you can use the default
+       settings (CID mode).
+     - If you have several DECT data devices (M10x) which you want to use
+       in turn, select Unimodem mode by passing the parameter "cidmode=0" to
+       the driver ("modprobe usb_gigaset cidmode=0" or modprobe.conf).
+
+     If you want both of these at once, you are out of luck.
+
+     You can also use /sys/module/<name>/parameters/cidmode for changing
+     the CID mode setting (<name> is usb_gigaset or bas_gigaset).
+
+
+3.   Troubleshooting
+     ---------------
+3.1. Solutions to frequently reported problems
+     -----------------------------------------
+     Problem:
+        You have a slow provider and isdn4linux gives up dialing too early.
+     Solution:
+        Load the isdn module using the dialtimeout option. You can do this e.g.
+        by adding a line like
+
+           options isdn dialtimeout=15
+
+        to /etc/modprobe.conf. If your distribution has some local module
+        configuration file like /etc/modprobe.conf.local,
+        using that should be preferred.
+
+     Problem:
+        Your isdn script aborts with a message about isdnlog.
+     Solution:
+        Try deactivating (or commenting out) isdnlog. This driver does not
+        support it.
+
+     Problem:
+        You have two or more DECT data adapters (M101/M105) and only the
+        first one you turn on works.
+     Solution:
+        Select Unimodem mode for all DECT data adapters. (see section 2.4.)
+
+3.2. Telling the driver to provide more information
+     ----------------------------------------------
+     Building the driver with the "Gigaset debugging" kernel configuration
+     option (CONFIG_GIGASET_DEBUG) gives it the ability to produce additional
+     information useful for debugging.
+
+     You can control the amount of debugging information the driver produces by
+     writing an appropriate value to /sys/module/gigaset/parameters/debug, e.g.
+        echo 0 > /sys/module/gigaset/parameters/debug
+     switches off debugging output completely,
+        echo 0x10a020 > /sys/module/gigaset/parameters/debug
+     enables the standard set of debugging output messages. These values are
+     bit patterns where every bit controls a certain type of debugging output.
+     See the constants DEBUG_* in the source file gigaset.h for details.
+
+     The initial value can be set using the debug parameter when loading the
+     module "gigaset", e.g. by adding a line
+        options gigaset debug=0
+     to /etc/modprobe.conf, ...
+
+     Generated debugging information can be found
+     - as output of the command
+         dmesg
+     - in system log files written by your syslog daemon, usually
+       in /var/log/, e.g. /var/log/messages.
+
+3.3. Reporting problems and bugs
+     ---------------------------
+     If you can't solve problems with the driver on your own, feel free to
+     use one of the forums, bug trackers, or mailing lists on
+         http://sourceforge.net/projects/gigaset307x
+     or write an electronic mail to the maintainers.
+
+     Try to provide as much information as possible, such as
+     - distribution
+     - kernel version (uname -r)
+     - gcc version (gcc --version)
+     - hardware architecture (uname -m, ...)
+     - type and firmware version of your device (base and wireless module,
+       if any)
+     - output of "lsusb -v" (if using an USB device)
+     - error messages
+     - relevant system log messages (it would help if you activate debug
+       output as described in 3.2.)
+
+     For help with general configuration problems not specific to our driver,
+     such as isdn4linux and network configuration issues, please refer to the
+     appropriate forums and newsgroups.
+
+3.4. Reporting problem solutions
+     ---------------------------
+     If you solved a problem with our drivers, wrote startup scripts for your
+     distribution, ... feel free to contact us (using one of the places
+     mentioned in 3.3.). We'd like to add scripts, hints, documentation
+     to the driver and/or the project web page.

@@ -0,0 +1,166 @@
+
+The sync patches work is based on initial patches from
+Krisztian <hidden@balabit.hu> and others and additional patches
+from Jamal <hadi@cyberus.ca>.
+
+The end goal for syncing is to be able to insert attributes + generate
+events so that the an SA can be safely moved from one machine to another
+for HA purposes.
+The idea is to synchronize the SA so that the takeover machine can do
+the processing of the SA as accurate as possible if it has access to it.
+
+We already have the ability to generate SA add/del/upd events.
+These patches add ability to sync and have accurate lifetime byte (to
+ensure proper decay of SAs) and replay counters to avoid replay attacks
+with as minimal loss at failover time.
+This way a backup stays as closely uptodate as an active member.
+
+Because the above items change for every packet the SA receives,
+it is possible for a lot of the events to be generated.
+For this reason, we also add a nagle-like algorithm to restrict
+the events. i.e we are going to set thresholds to say "let me
+know if the replay sequence threshold is reached or 10 secs have passed"
+These thresholds are set system-wide via sysctls or can be updated
+per SA.
+
+The identified items that need to be synchronized are:
+- the lifetime byte counter
+note that: lifetime time limit is not important if you assume the failover
+machine is known ahead of time since the decay of the time countdown
+is not driven by packet arrival.
+- the replay sequence for both inbound and outbound
+
+1) Message Structure
+----------------------
+
+nlmsghdr:aevent_id:optional-TLVs.
+
+The netlink message types are:
+
+XFRM_MSG_NEWAE and XFRM_MSG_GETAE.
+
+A XFRM_MSG_GETAE does not have TLVs.
+A XFRM_MSG_NEWAE will have at least two TLVs (as is
+discussed further below).
+
+aevent_id structure looks like:
+
+   struct xfrm_aevent_id {
+             struct xfrm_usersa_id           sa_id;
+             __u32                           flags;
+   };
+
+xfrm_usersa_id in this message layout identifies the SA.
+
+flags are used to indicate different things. The possible
+flags are:
+        XFRM_AE_RTHR=1, /* replay threshold*/
+        XFRM_AE_RVAL=2, /* replay value */
+        XFRM_AE_LVAL=4, /* lifetime value */
+        XFRM_AE_ETHR=8, /* expiry timer threshold */
+        XFRM_AE_CR=16, /* Event cause is replay update */
+        XFRM_AE_CE=32, /* Event cause is timer expiry */
+        XFRM_AE_CU=64, /* Event cause is policy update */
+
+How these flags are used is dependent on the direction of the
+message (kernel<->user) as well the cause (config, query or event).
+This is described below in the different messages.
+
+The pid will be set appropriately in netlink to recognize direction
+(0 to the kernel and pid = processid that created the event
+when going from kernel to user space)
+
+A program needs to subscribe to multicast group XFRMNLGRP_AEVENTS
+to get notified of these events.
+
+2) TLVS reflect the different parameters:
+-----------------------------------------
+
+a) byte value (XFRMA_LTIME_VAL)
+This TLV carries the running/current counter for byte lifetime since
+last event.
+
+b)replay value (XFRMA_REPLAY_VAL)
+This TLV carries the running/current counter for replay sequence since
+last event.
+
+c)replay threshold (XFRMA_REPLAY_THRESH)
+This TLV carries the threshold being used by the kernel to trigger events
+when the replay sequence is exceeded.
+
+d) expiry timer (XFRMA_ETIMER_THRESH)
+This is a timer value in milliseconds which is used as the nagle
+value to rate limit the events.
+
+3) Default configurations for the parameters:
+----------------------------------------------
+
+By default these events should be turned off unless there is
+at least one listener registered to listen to the multicast
+group XFRMNLGRP_AEVENTS.
+
+Programs installing SAs will need to specify the two thresholds, however,
+in order to not change existing applications such as racoon
+we also provide default threshold values for these different parameters
+in case they are not specified.
+
+the two sysctls/proc entries are:
+a) /proc/sys/net/core/sysctl_xfrm_aevent_etime
+used to provide default values for the XFRMA_ETIMER_THRESH in incremental
+units of time of 100ms. The default is 10 (1 second)
+
+b) /proc/sys/net/core/sysctl_xfrm_aevent_rseqth
+used to provide default values for XFRMA_REPLAY_THRESH parameter
+in incremental packet count. The default is two packets.
+
+4) Message types
+----------------
+
+a) XFRM_MSG_GETAE issued by user-->kernel.
+XFRM_MSG_GETAE does not carry any TLVs.
+The response is a XFRM_MSG_NEWAE which is formatted based on what
+XFRM_MSG_GETAE queried for.
+The response will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs.
+*if XFRM_AE_RTHR flag is set, then XFRMA_REPLAY_THRESH is also retrieved
+*if XFRM_AE_ETHR flag is set, then XFRMA_ETIMER_THRESH is also retrieved
+
+b) XFRM_MSG_NEWAE is issued by either user space to configure
+or kernel to announce events or respond to a XFRM_MSG_GETAE.
+
+i) user --> kernel to configure a specific SA.
+any of the values or threshold parameters can be updated by passing the
+appropriate TLV.
+A response is issued back to the sender in user space to indicate success
+or failure.
+In the case of success, additionally an event with
+XFRM_MSG_NEWAE is also issued to any listeners as described in iii).
+
+ii) kernel->user direction as a response to XFRM_MSG_GETAE
+The response will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs.
+The threshold TLVs will be included if explicitly requested in
+the XFRM_MSG_GETAE message.
+
+iii) kernel->user to report as event if someone sets any values or
+thresholds for an SA using XFRM_MSG_NEWAE (as described in #i above).
+In such a case XFRM_AE_CU flag is set to inform the user that
+the change happened as a result of an update.
+The message will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs.
+
+iv) kernel->user to report event when replay threshold or a timeout
+is exceeded.
+In such a case either XFRM_AE_CR (replay exceeded) or XFRM_AE_CE (timeout
+happened) is set to inform the user what happened.
+Note the two flags are mutually exclusive.
+The message will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs.
+
+Exceptions to threshold settings
+--------------------------------
+
+If you have an SA that is getting hit by traffic in bursts such that
+there is a period where the timer threshold expires with no packets
+seen, then an odd behavior is seen as follows:
+The first packet arrival after a timer expiry will trigger a timeout
+aevent; i.e we dont wait for a timeout period or a packet threshold
+to be reached. This is done for simplicity and efficiency reasons.
