Since this meta information should not be counted as LLC octets, the gprs_llc_queue needs to known about this (unless the correction was done in the LLC layer). This commit moves the meta information storage code into gprs_llc_queue. The meta data is now stored in the control block (cb) area of the msgb. Note that the info pointer that is returned from the dequeue method is only valid if that method returns a (non-NULL) msgb. It must not be used after that msgb has been modified or freed.

We can't know which BSC it is at this point and I don't want to send another message once the token has been received so always send the data with an undefined code. The old BSCs don't parse the message and will happily ignore the RAND. /dev/urandom can give short reads on Linux so loop around it until the bytes have been read from the kernel. http://cgit.osmocom.org/openbsc/commit/?id=7b608771dd1d4ded5ebf576b1462a0c1… commit 7b608771dd1d4ded5ebf576b1462a0c12452f0fe Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Mon Jun 8 11:56:59 2015 +0200 nat: Provide access to /dev/urandom for the code Instead of doing open/read/close all the time, open the FD in the beginning and keep it open. To scare me even more I have seen /dev/urandom actually providing a short read and then blocking but it seems to be the best way to get the random byes we need for authentication. So one should/could run the cheap random generator on the system (e.g. haveged) or deal with the NAT process to block. http://cgit.osmocom.org/openbsc/commit/?id=ad46558c54c3de17af2df2ccae46361c… commit ad46558c54c3de17af2df2ccae46361cb7743332 Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Wed Jun 10 11:51:16 2015 +0200 bsc/nat: Fix the structure of the identity request message Unfortunately the basic structure of the response is broken. There is a two byte length followed by data. The concept of a 'tag' happens to be the first byte of the data. This means we want to write strlen of the token, then we want to write the NUL and then we need to account for the tag in front. Introduce a flag if the new or old format should be used. This will allow to have new BSCs talk to old NATs without an additional change. In the long run we can clean that up. http://cgit.osmocom.org/openbsc/commit/?id=fc9a3ff9dc3801c4ec6927cc80ec2625… commit fc9a3ff9dc3801c4ec6927cc80ec2625d1332d65 Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Mon Jun 8 11:55:02 2015 +0200 nat: Close the connection after we couldn't find the user In case the token was not correct, just close the connection. It is not clear that forcing a new TCP connection is going to give us any extra security here. But with the upcoming auth handling it does make sense to have both case look similar. http://cgit.osmocom.org/openbsc/commit/?id=08ff087c9989822d2b0fe344264b95d0… commit 08ff087c9989822d2b0fe344264b95d0343b6676 Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Mon Jun 8 09:54:45 2015 +0200 nat: Factor out the config by token search In the upcoming authentication improvements it is nice to separate the finding of the config from the post-allow handling of it. http://cgit.osmocom.org/openbsc/commit/?id=3d07ca5e2f23bc86b9f938efd93ef333… commit 3d07ca5e2f23bc86b9f938efd93ef3331ddc41cd Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Mon Jun 8 18:31:02 2015 +0200 nat: Add size check for the payload The msgb will always have these bytes but it is better practice to verify that the message really has space for the two bytes. ----------------------------------------------------------------------- hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)

This has been shown by Chen and Goodman in their paper "Theoretical Analysis of GPRS Throughput and Delay". See their throughput over C/I measurement graphs (figures 4 and 5 in the paper) for details. This commit implements a simplified CS downgrade feature for the downlink. The coding scheme will be downgraded if there are only a few octets are left to be send over the TBF (see the downgrade-threshold command below) and the NACK rate is not low (the CS will not get degraded on a high quality RF link). As an exception, CS-3 will be degraded to CS-1, since CS-2 does not improve the throughput in general when a few small packets are sent and the signal fades slowly (see Chen/Goodman). The following VTY command is added to the config-pcu node: - cs downgrade-threshold <1-10000> - cs no downgrade-threshold to set the threshold of the number of remaining bytes to be RLC/MAC encoded. The CS will only be reduced, if the number is below the threshold. The 'no' command disables this feature completely. The default value is 200 octets.

If the interval is above the time where the DL TBF is in state FLOW (mainly influenced be the dl-tbf-idle-time command), an new TBF must be requested via AGCH for each ICMP PING message. Currently the LLC frame containing the PING is immediately stored in the TBF and gets lost, if TBF establishment fails for some reason. This commit moves all calls to put_frame() to schedule_next_frame(), where the data is moved from the LLC queue to the frame storage within the TBF object. This method is only called from within create_new_bsn() when the TBF is in the FLOW state and the frame is going to be encoded immediately. At all other places, where put_frame() has been called before, the LLC message is just appended to the LLC queue in the GprsMs object. This change effectively simplifies the related code parts, since date/len information and discard notifications is no longer needed there.

This test tries to reproduce this behaviour by throwing away the first TBF while calling the handle() method several times. The results of create_dl_acked_block() are checked against expected values (this is currently party disabled because the bug still persists).

They do not seem to be contained in messages recorded via gsmtab. To help debugging this issue, this commit adds related debug messages that are generated while the encoded values are taken from the RLC/MAC messages.

The encoded values are remapped to dB respectively % values. The values are stored in the corresponding MS object (if there is one). Note that the values are store as (rounded) integers, so some different encodings are mapped to the same decoded value.

This approach does not reflect the general situation of the RF link between ME and BTS, which is rather asymmetric e.g. due to a lower degree of TX efficiency of the built-in antenna. This means, that UL and DL CS control should be decoupled for better results. This commit adds automatic UL CS selection based on the link quality measurement parameter. Each coding scheme is mapped to a link quality range. If the link quality value leaves that range, the current UL CS value is increased/decreased accordingly. This value will be copied when the next PACKET_UPLINK_ACK_NACK or PACKET_UPLINK_ASSIGMENT is sent to the MS. The following VTY command will be added to the config-pcu node: - cs link-quality-ranges cs1 <0-35> cs2 <0-35> <0-35> cs3 <0-35> <0-35> cs4 <0-35> which sets the ranges for the four coding schemes. For instance the example below reflects the current default values: cs link-quality-ranges cs1 6 cs2 5 8 cs3 7 13 cs4 12 set the following ranges, where the overlapping is used to configure a hysteresis: CS1: -inf .. 6 CS2: 5 .. 8 CS3: 7 .. 13 CS4: 12 .. inf Sponsored-by: On-Waves ehf http://cgit.osmocom.org/osmo-pcu/commit/?id=3bea905e0d013de9a0b9d77fdc5318a… commit 3bea905e0d013de9a0b9d77fdc5318a133a6af9b Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Mon Jun 8 11:26:38 2015 +0200 ms: Store the L1 measurement values in the MS objects This commits adds the GprsMs::update_l1_meas() and GprsMs::l1_meas() methods to store and access the measurement values. The internal state is updated depending on which values are actually set. In addition, these values are shown in the output of the 'show ms imsi|tlli' command.

Other values like TA and BER which are needed for TA update respectively CS selection are not propagated. This commit introduces and passes a struct that contains a set of measurement values.
