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=fce6971fe3673e8269414188fda0ce3b… commit fce6971fe3673e8269414188fda0ce3b28b5cf03 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=8a8df80772a4bac0f3cb4d384f45a5d4… commit 8a8df80772a4bac0f3cb4d384f45a5d4c463fe11 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=0363d1bb97663e83aa0dc3a1e6b425b1… commit 0363d1bb97663e83aa0dc3a1e6b425b1870dd271 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=aa0cecd9b7986254983af6b6cbef2911… commit aa0cecd9b7986254983af6b6cbef291183709ca0 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=2dd18bdd87a130a3536b12af874e331d… commit 2dd18bdd87a130a3536b12af874e331d93593e9b 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. ----------------------------------------------------------------------- Summary of changes: openbsc/include/openbsc/bsc_msc.h | 2 +- openbsc/include/openbsc/bsc_nat.h | 7 ++ openbsc/include/openbsc/osmo_msc_data.h | 3 + openbsc/src/libbsc/bsc_msc.c | 22 ++++- openbsc/src/osmo-bsc/osmo_bsc_msc.c | 58 +++++++++++- openbsc/src/osmo-bsc/osmo_bsc_vty.c | 29 ++++++ openbsc/src/osmo-bsc_nat/bsc_nat.c | 156 +++++++++++++++++++++++++------ openbsc/src/osmo-bsc_nat/bsc_nat_utils.c | 18 ++++ openbsc/src/osmo-bsc_nat/bsc_nat_vty.c | 32 ++++++- 9 files changed, 291 insertions(+), 36 deletions(-) hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)
