I means: is the interaction with mtp3 layer implemented (is sending sccp data by mtp3 implemented by the library?)? Also, what about the reception of data from mtp3 layer. is that implemented in the sccp lib. I am asking these questions because I see the code of mtp3 in the lib but no significant call is present in the sccp part of the lib. Thank you for your help.

dynamic traffic channels

A TS can be GSM_PCHAN_TCH_F_PDCH; those are the only ones for which we send a PDCH ACT message. We send a PDCH ACT message - during init (CHANNEL OML's state changed to enabled -> send PDCH ACT), - and upon channel release ack when pchan == GSM_PCHAN_TCH_F_PDCH. So the question is, when we receive a channel release ack, could that be the PDCH release and we switch PDCH right back on by accident? No, because we only receive a chan rel ack when the *TCH/F* is being released. That is because the PDCH release is initiated "internally" from the PDCH DEACT, and thus this condition in common/rsl.c rsl_tx_rf_rel_ack() catches on, which existed before dyn PDCH: if (lchan->rel_act_kind != LCHAN_REL_ACT_RSL) { LOGP(DRSL, LOGL_NOTICE, "%s not sending REL ACK\n", gsm_lchan_name(lchan)); return 0; } In rsl_rx_rf_chan_rel() the rel_act_kind is set to LCHAN_REL_ACT_RSL, but not in the rsl_rx_dyn_pdch(). This is analogous to the ip.access way -- the ip.access nanobts replies to a PDCH DEACT with a PDCH DEACT ACK and doesn't send a separate channel release ack. Maybe we could set rel_act_kind to some new LCHAN_REL_ACT_IPAC_DYN_PDCH for clarity? (But we shouldn't actually send a release ack, to stay compatible.) Even though it works as-is, we should indeed add another flag check: - We do check the flags that no ACT/DEACT is already pending; - And we do send a PDCH DEACT only if ts->flags & TS_F_PDCH_ACTIVE; - But we would send a PDCH ACT despite ts->flags & TS_F_PDCH_ACTIVE. This should never happen, but it would make sense to ensure that. ~Neels

osmo-sip-connector in bad state

[PATCH net-next v2 0/6] gtp: misc improvements

by Andreas Schultz

Hi Pablo, Resent as v2, because I forgot the net-next target. Sorry for noise, I promise I won't forget it again. This series lays the groundwork for removing the socket references from the GTP netdevice by removing duplicate code and simplifying the logic on some code paths. It slighly changes the GTP genl API by making the socket parameters optional (though one of them is still required). The removal of the socket references will break the 1:1 releation between GTP netdevice and GTP socket that prevents us to support multiple VRFs with overlaping IP addresse spaces attached to the same GTP socket (needed for multi APN support). Regards Andreas Andreas Schultz (6): gtp: make GTP sockets in gtp_newlink optional gtp: merge gtp_get_net and gtp_genl_find_dev gtp: unify genl_find_pdp and prepare for per socket lookup gtp: consolidate pdp context destruction into helper gtp: add socket to pdp context gtp: consolidate gtp socket rx path drivers/net/gtp.c | 564 +++++++++++++++++++++++++++--------------------------- 1 file changed, 280 insertions(+), 284 deletions(-) -- 2.10.2

[PATCH 0/6] gtp: misc improvements

by Andreas Schultz

Hi Pablo, This series lays the groundwork for removing the socket references from the GTP netdevice by removing duplicate code and simplifying the logic on some code paths. It slighly changes the GTP genl API by making the socket parameters optional (though one of them is still required). The removal of the socket references will break the 1:1 releation between GTP netdevice and GTP socket that prevents us to support multiple VRFs with overlaping IP addresse spaces attached to the same GTP socket (needed for multi APN support). Regards Andreas -- Andreas Schultz (6): gtp: make GTP sockets in gtp_newlink optional gtp: merge gtp_get_net and gtp_genl_find_dev gtp: unify genl_find_pdp and prepare for per socket lookup gtp: consolidate pdp context destruction into helper gtp: add socket to pdp context gtp: consolidate gtp socket rx path drivers/net/gtp.c | 564 +++++++++++++++++++++++++++--------------------------- 1 file changed, 280 insertions(+), 284 deletions(-) -- 2.10.2
