Add case handling for only authentication without ciphering (basically just fill in the blanks). http://cgit.osmocom.org/openbsc/commit/?id=837c6e43019a0afcf255640d591f16b3… commit 837c6e43019a0afcf255640d591f16b3b0bb59ce Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Tue Mar 8 15:14:59 2016 +0100 HACK: hardcode subscriber auth tuple for IuCS http://cgit.osmocom.org/openbsc/commit/?id=9499d053f96ae8e5cb75a189317b5232… commit 9499d053f96ae8e5cb75a189317b5232504d0f0d Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon Mar 7 16:53:45 2016 +0100 cosmetic http://cgit.osmocom.org/openbsc/commit/?id=49ee79f132b54346dfbd2fab44ebfb25… commit 49ee79f132b54346dfbd2fab44ebfb25e2126640 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon Mar 7 16:53:02 2016 +0100 Adjust authentication logic for Iu, move a log notice Depending on conn->via_iface, fail upon missing auth for 3G.

Note that the upcoming Iu auth will probably add a GSM_SECURITY_AUTH_FAILED status. In that case, sending a LU Reject immediately may be desirable, but arguably a bit of timeout could make life harder for auth attackers. The code removed by this patch doesn't send out a LU Reject ever, since a call to release_loc_updating_req() only releases the connection. To reject, a call to gsm0408_loc_upd_rej() would be necessary, as seen in loc_upd_rej_cb(). And finally, if _gsm0408_authorize_sec_cb() doesn't do anything about anything, the same loc_upd_rej_cb() will be run by a timeout and send a LU Reject properly (as commented in the code). http://cgit.osmocom.org/openbsc/commit/?id=0c39c0d08e2c76f91128b39b9e83e7d8… commit 0c39c0d08e2c76f91128b39b9e83e7d857b5204a Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Thu Mar 10 12:23:26 2016 +0100 GSM 04.08 message types: fix use of bitmasks According to spec, the bitmasks for message types apply only for MM and CC messages. However, various code used the bitmask even though no MM or CC messages are involved: bsc_msg_filter.c: bsc_msg_filter_initial(): use bitmasked msg_type_mm for MM messages, use unmasked msg_type for RR. osmo_bsc_filter.c: bsc_find_msc() and bsc_scan_bts_msg(): use msg_type_mm for MM, unmasked for RR. bsc_nat_rewrite.c: bsc_nat_rewrite_msg(): use msg_type_cc for CC, unmasked for SMS. bsc_ussd.c: don't mask, no MM nor CC involved. http://cgit.osmocom.org/openbsc/commit/?id=8ac13ec22931e147864c363c6bece158… commit 8ac13ec22931e147864c363c6bece158f56bed9e Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Thu Mar 10 12:19:13 2016 +0100 GSM 04.08 message types: apply bitmask makros In libosmocore, MM and CC message type bitmask makros were introduced. Replace hardcoded bitmasks with these makros. Also replace the protocol discriminator mask 0x0f with GSM48_PDISC_MASK. Note: in some places, use of the bitmask is doubtful. This commit so far applies the makros without changing anything. Also note: the MM bitmask is hardcoded as 0xbf, but libosmocore also adjusts the mask to the apparent de-facto standard of 0x3f, while the CC bitmask is so far left unchanged at 0xbf. So where in doubt, use the CC bitmask. ----------------------------------------------------------------------- Summary of changes: openbsc/include/openbsc/auth.h | 2 +- openbsc/src/libfilter/bsc_msg_filter.c | 15 ++-- openbsc/src/libmsc/auth.c | 4 +- openbsc/src/libmsc/gsm_04_08.c | 139 +++++++++++++++++++++++------ openbsc/src/libmsc/gsm_subscriber.c | 1 - openbsc/src/osmo-bsc/osmo_bsc_api.c | 8 +- openbsc/src/osmo-bsc/osmo_bsc_filter.c | 15 ++-- openbsc/src/osmo-bsc_nat/bsc_nat.c | 4 +- openbsc/src/osmo-bsc_nat/bsc_nat_rewrite.c | 9 +- openbsc/src/osmo-bsc_nat/bsc_ussd.c | 4 +- openbsc/src/osmo-cscn/cscn_main.c | 4 +- 11 files changed, 148 insertions(+), 57 deletions(-) hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)
