Changes

Fix unhandled (un)mapping events

If a mapping event (create slotmap) and an unmapping event (delete
slotmap) exists at the same time, none of these events were handled.
These mappings stayed in 'NEW' state. Subsequent mappings of different
slots were then ignored.

This issue has been reproduced and is fixed with this patch.

TCAP loadshare: Rework initial selection of a node

The TCAP loadshare original used the OTID of a TCAP Begin to select
the node. To improve the load share across the nodes,
use a round robin as initial selection, but "stick" the session
on the particular node.

vty: update help string for nokia_site model

Original Nokia BTS support in OsmoBSC was limited to MetroSite,
UltraSite and InSite, aka the Site family.  After the recent series
of fixes, the same code also supports Flexi Multiradio (actively
used in the present) and will most likely also work on Flexi EDGE
(intermediate between UltraSite and Flexi MR), although that model
is currently untested.

BTS model name "nokia_site" is thus outdated and inaccurate now.
It has been decided (see https://gerrit.osmocom.org/c/osmo-bsc/+/42729)
to keep this model name unchanged for now, given the uncertainty
of how Nokia BTS support will evolve in the future if and when
we implement support for IP Abis on Flexi family, potentially
followed by future support for subsequent IP-only models.

In the meantime, change vty help string to reflect current support
for both Site and Flexi families with the same model selection.

nokia: rename BTS model from nokia_site to nokia-e1

When Nokia BTS support was introduced into Osmocom in 2011, only
{Metro,Ultra,In}Site family was supported, and the name of this
BTS model in OsmoBSC was set to nokia_site.  However, we now
also support Flexi Multiradio in E1 Abis configuration with the
same code, automatically applying Site-specific or Flexi-MR-
specific handling based on the type code returned by the BTS
itself - hence calling the BTS model nokia_site and referring
strictly to *Site in docs and vty help is now misleading.

At the same time, these newer BTS models support both E1 and IP
Abis options, and there is a desire to support IP Abis operation
at some point in the future.  When/if Nokia IP support becomes a
reality, we will certainly need to know upfront which type of Abis
we are working with, similarly to how we currently distinguish
upfront between E1 and IPA types of BTS.  Therefore, the new BTS
model name is set to nokia-e1, rather than just "nokia", with the
expectation that we will also have nokia-ip in the future.

bts_nokia_site.c source file name is deliberately left unchanged.
Source file renames make it difficult to follow changes, hence a
slightly outdated source file name is deemed to be a lesser evil.
This source file may also be split in the future as Nokia BTS
support code grows.

lint/checkpatch: ignore STATIC_CONST_CHAR_ARRAY

include/osmocom/vty/command.h has the following:

  #define DEFUN_CMD_FUNC_DECL(funcname) \

  #define DEFUN_CMD_FUNC_TEXT(funcname) \
    static int funcname \
      (struct cmd_element *self, struct vty *vty, int argc, const char *argv[])

So the pointer to argv is const, but the elements in the array are not.
Functions can in theory modify the elements of argv (just like argv in
main()). I don't know if we have users of this API that are actually
doing that, but as long as the API is defined like this it doesn't make
sense for the linter to complain about using it correctly. Therefore,
ignore STATIC_CONST_CHAR_ARRAY.

- Use LUT-based modulation for sps=4 when enabled
- Add configure.ac option and USE_BURST_LUT define

This reduces runtime computation by replacing per-burst Laurent
processing with memcpy-based LUT lookups.

nokia cosmetic: add bts_is_insite() function

Nokia InSite gets a different config than the larger Nokia BTS models,
and make_bts_config() function checks the BTS type to decide which
config to send.  Change the BTS type check from a long 'if' line that
compares against 3 different InSite BTS type codes to bts_is_insite()
helper function that encapsulates a switch statement.

Upcoming code additions will need to check for Flexi Multiradio BTS
family in a similar manner - so be consistent.

nokia cosmetic: factor out BTS_CONF_COMPL handling

When the BTS accepts the config sent to it via BTS_CONF_DATA, it
responds with BTS_CONF_COMPL.  Upon receiving the latter message,
we have to send TRX unlock and TRX reset commands, and we have to
start LAPD for RSL.  Factor out this logic into a helper function,
to reduce the level of indentation and make it easier to extend.

Nokia Flexi Multiradio: reset non-BCCH TRX

In the case of MetroSite and UltraSite BTS, it has been determined
empirically that TRX reset needs to be skipped for non-BCCH TRX.
However, the opposite situation holds on Flexi MR: non-BCCH TRX
do need to be reset, or they fail to come up.  Solution:
conditionalize reset of non-BCCH TRX on Nokia BTS type.

Fix: Reject TPDUs fromm host with less than 5 bytes

Each TPDU includes a header with at least 5 bytes. tpdu_s_init_action()
expects at least 5 bytes, so we need to reject Transfer Block commands
with less than 5 bytes payload.

Previous support existed for Nokia MetroSite, UltraSite and InSite
models, resulting in BTS model name "nokia_site".  However, there
exist newer Nokia BTS models that also support E1 Abis and can be
supported by OsmoBSC with relatively small changes: Flexi EDGE,
Flexi Multiradio and Flexi Multiradio 10.  Out of these newer
models, American 2G Cooperative (the present patch author's current
organization) has only Flexi MR at the present time - hence this
model shall be the first "new" Nokia BTS to be supported.

The first change required in order to support Flexi MR is ability
to receive long OML messages that have been segmented by the BTS:
the new BTS sends a much longer BTS_CONF_REQ message, and we have
to handle it correctly.

rsl: don't send legacy Chan Ident IE for Nokia BTS

The description of CHAN ACTIV command message in TS 48.058
section 8.4.1 lists Channel Identification as an optional IE,
with a note that reads "Included if compatibility with phase1

referring to compatibility with Phase 1 phones - but since
this network-internal Abis detail is invisible to phones,
the real intent of GSM spec authors here must have been
compatibility with Phase 1 BTS.

Previous versions of OsmoBSC would always include this IE,
and it appears that all previously supported BTS models
would simply ignore it.  However, newer Nokia BTS models
(observed on Flexi Multiradio at least) dislike this IE
and return CHAN ACTIV NACK with an optional IE error cause
if it is included.

To avoid changing OsmoBSC behavior for other users, let us
conditionalize removal of this legacy IE on Nokia BTS for now.
This change has been tested on InSite, MetroSite and Flexi

jobs/ttcn3-testsuites-testenv: fix rm apt partial

Fix that testenv jobs may fail to remove the cache at the beginning:

  rm: cannot remove '_cache/podman/var-lib-apt-debian-trixie/lists/partial': Permission denied

This happens when the partial directory still exists:

SIGPIPE is sent to the worker, causing the application to exit.

To prevent this, all workers have a dummy handler to prevent this. Now

Fix: Prevent race conditions when accessing slotmap in bankd

All threads (main and workers) can use slotmap_by_bank() and
slotmap_by_client() to get a mapping entry from the slot map. While
working with this entry (reading values), it could be deleted by a
different thread.

For example, if a client connects to a worker, the worker will check if
there is an existing mapping between a reader and this client. If it
exists, slotmap_by_client() will return a pointer. If the mapping is
deleted at this time by the server, the worker uses a pointer to a
mapping entry that has just been freed.

Fix: Remove slot mapping at bankd when client disconnects

If a client disconnects before removing the slot mapping, the worker
must undefine its 'bank_id' and 'slot_nr' and must change its state to
'UNMAPPED'.

send_signal_to_worker() searches for a worker that has a given bank and
slot. If a client re-connects to a different worker and if the bank and
slot would be still assigned to the old worker, the old worker could
receive signals when assigning or removing slot mapping. The new worker
would not be mapped.

ts_51_011/EF.SMSP: fix handling of 'alpha_id' field

pySim-prog/cards: fix programming of EF.SMSP

The legacy code found in legacy/cards.py does not use the modern
construct based encoder (pySim-read uses it). The card classes either
use their own implementation of update_smsp or use the generic method
provided by the SimCard class. The latter one is true for FairwavesSIM
and WavemobileSim.

Unfortunately the implementation found in the SimCard is wrong. It
adds padding at the end of the file instead of the beginning. This
completely messes up the contents of EF.SMSP for the cards using this
method. To fix this, let's use the leftpad feature provided by
the update_record. This will ensure a correct alignment of the file
contents.

HDLC timeslots: fix Rx of maximum-sized frames

E1D protocol sets the maximum permitted size of an HDLC frame to
264 bytes of useful payload, not counting the 2 bytes of FCS.
This limit is fair enough, as it matches GSM TS 08.56, the primary
intended application.  However, osmo_isdnhdlc engine used internally
by the daemon requires an Rx buffer 2 bytes larger than the maximum
payload length, for temporary storage of FCS bytes: by the nature
of HDLC, a receiver has no way of identifying FCS bytes as such
until after they have been received and stored in the Rx buffer.

This bug was caught when bringing up OsmoBSC with Nokia Flexi
Multiradio BTS.  This BTS emits some long OML messages that get
broken into segments, with each not-last segment traveling over
HDLC as a maximum-sized frame - and these frames then get dropped
by osmo-e1d, causing further breakage downstream.

lapd_sap_stop(): fix use of uninitialized stack memory

DL-RELEASE in lapd_core can be done in two ways: by sending DISC
and waiting for UA, or a purely local clearing of state.  The
selection between these two modes is communicated via an extended
field in struct osmo_dlsap_prim that extends beyond the standard
struct osmo_prim_hdr.  lapd_sap_stop() is a wrapper function that
sends DL-RELEASE to lapd_core; its only current users are the
vendor-specific E1 BTS handlers for Ericsson and Nokia in OsmoBSC,
and both of those need local release handling.  This wrapper
function does allocate correctly-sized struct osmo_dlsap_prim
on the stack, but until now it failed to initialize the extended
field - hence the actual behavior was subject to laws of chance,
depending on uninitialized content of stack memory.

saip SmspTpScAddr: safeguard against decoding error

Reading the TS48 V6.0 eSIM_GTP_SAIP2.1A_NoBERTLV profile results in an
exception [1] in SmspTpScAddr. I have a caller that needs to skip
erratic values instead of raising.

The underlying issue, I presume, is that either the data needs
validation before decode_record_bin(), or decode_record_bin() needs
well-defined error handling.

So far I know only of this IndexError, so, as a workaround, catch that.

personalization: fix SdKey.apply_val() implementation

'securityDomain' elements are decoded to ProfileElementSD instances,
which keep higher level representations of the key data apart from the
decoded[] lists.

So far, apply_val() was dropping binary values in decoded[], which does
not work, because ProfileElementSD._pre_encode() overwrites
self.decoded[] from the higher level representation.

Implement using
- ProfileElementSD.find_key() and SecurityDomainKeyComponent to modify
  an exsiting entry, or
- ProfileElementSD.add_key() to create a new entry.

Before this patch, SdKey parameters seemed to patch PES successfully,
but their modifications did not end up in the encoded DER.

(BTW, this does not fix any other errors that may still be present in
the various SdKey subclasses, patches coming up.)
