Harald Welte ea7b53850b cosmetic: Clarify language ip.access nanoBTS vs. all IPA Abis/IP
Don't explicitly mention ip.access/nanoBTS if we actually want to refer
to all BTSs implementing an IPA-style Abis/IP interface.

Also, remove some bogus "is_ipa_abisip_bts(bts) || is_osmobts(bts)".
is_ipa_abisip_bts includes osmobts.

Harald Welte ceccba70a9 cosmetic: Rename is_ipaccess_bts() to is_ipa_abisip_bts()
This function is used to check if the BTS is using the IPA Abis-IP
transport, and not whether its manufacturer/vendor is ip.access.

Let's use a less confusing name.

Harald Welte 5d8ab13b34 abis_nm: Only osmo-bts re-purposes the MANUF_ID for BTS feature flags
The Manufacturer ID IE is normally used to indicate the [name of] the
manufacturer.  In case of ip.access nanoBTS it is, for example, "com.ipaccess".

Osmocom decided to re-pupose this IE to indicate bts-specific feature
flags.  Stop interpreting the string "com.ipaccess" as feature bitmap.

In fact, nanoBTS doesn't support runtime reporting of features (at
least not in this way), so let's mark features_get_reported = false,
resulting in the copy of bts_model->features to bts->features at the
time a BTS is initialized.

Use the proper type that can handle the entire range of MSC numbers we
allow on the VTY, we have:
 #define MSC_NR_RANGE "<0-1000>"

Before this patch, MSC pool round robin would glitch around for any

Neels Hofmeyr a70d6b25c4 fix length check in abis_rsl_rx_rll()
In abis_rsl_rx_rll(), we do the following header length check -- quick
challenge, can you spot the two bugs hidden here?

  struct abis_rsl_rll_hdr *rllh;
  if (msgb_l2len(msg) >
      sizeof(struct abis_rsl_common_hdr) + sizeof(*rllh))
           msg->l3h = &rllh->data[3];

Fix these bugs:

- struct abis_rsl_common_hdr is already included as the first member of
  abis_rsl_rll_hdr, no need to add that.
- We are going to be accessing rrlh->data[3], so we must check for at
  least sizeof(*rllh) + 4.

Vadim Yanitskiy 16922c5017 bts: st_op_enabled_on_enter(): resume C0 power reduction
If power saving is enabled for a BTS, it should remain enabled even
if the BTS is restarted for whatever reason.  This persistence can be
achieved by re-sending the configured power reduction value whenever
the BTS NM FSM enters the ENABLED state again (i.e. reconnects).

Separate gsm_bts_send_c0_power_red() from gsm_bts_set_c0_power_red()
and call the former from st_op_enabled_on_enter().  All we need to do
is to send the value that was configured before, per-timeslot power
reduction limits remain and need not to be updated.

Take a chance to move logging from BTS specific to the generic code.

The situation apparently is conn->lchan == NULL (primary lchan is gone),

During assignment_success(), do not assume that conn->lchan is still

Pau Espin 9f7611a32f Fix Lb/A SCCP conn lookup after recent regression in optimization patch
In osmo-bsc, there's currently 0..1 Lb links and 0..N A links, where N
is the number of MSC, but links can be shared in the underlaying stack
(struct osmo_sccp_instance), hence range 0..N of different
osmo_sccp_instance (identified by PC).
Even more, the Lb and A link can share the same underlaying stack, so
osmo-bsc can end up with only 1 struct osmo_sccp_instance shared by all
the above mentioned links in case all are configured under the same PC.
Total range A+Lb is 0..(1+N).

A struct gsm_subscriber_conn stores 2 struct sccp_instance*, one for
Lb (conn->lcs.lb.*)and one for A (conn->sccp.*).
They can actually point to the same sccp_instance or to different ones,
as explained above, depending on the configured setup. In any case, a
gsm_subscriber_conn needs 2 rb_nodes since it can hold
any of the 2 conn_ids independently (A or Lb).

The previous patch forgot to add that 2nd rb_node as well as some
initialization and release code for the Lb conn. This patch addresses
that.

When the 2nd rb_node, a problem when iterating the rbtree appears: how to
find out the "conn" pointer from the rb_node pointer, since the rb_node pointer
can be any of the 2 rb_nodes inside the struct at a different offsets.

In order to solve that problem, a new struct bscp_sccp_conn_node is
added, which holds all the relevant information used by the rbtree lookup code
in a generic way (rb_node and conn_id), plus a backpointer to the struct
bsc_gsm_subcriber it relates too.
