This patch modifies openBSC code to use msg->dst which stores the
pointer to the signalling link structure instead of the pointer to
the transceiver structure.
This patch prepares the introduction of libosmo-abis.
Scenario: BTS are configured and working, then the BSC stops working
for some reason (crash or administrative stop).
If the BSC comes back to life, LAPD among other things does not know
about the previous existing TEIs. Instead of ignoring these frames,
we notify the driver that we are seeing frames with unknown TEIs, so
it can try to recover, e.g. by resending the SABM message.
DAHDI creates one device node for every E1 timeslot, starting from '1',
and keeps incrementing that number even for additional ports/cards.
Thus, we have to use the e1inp_line number multiplied by 31 as a base.
This patch fixes a segfault that occured when a ipaccess RSL link gets
closed unexpectedly.
The segfault can be provoked by connecting to the RSL port with ncat and
hitting ^C.
With this patch, we don't include e1_input if it's empty
[...]
timeslot 7
phys_chan_config TCH/F
hopping enabled 0
e1_input <----------------- empty, it should not show up.
msc
[...]
Now ipaccess_idtag_parse() returns -EINVAL instead of -1. We also
check for the return value of this function in every invocation to
skip further processing in case of messages with malformed TLVs.
This idea was suggested by Zecke.
* include/openbsc/ipaccess.h: Reserve a protocol number for control
commands
* input/ipaccess.c: New function ipaccess_prepend_header_ext prepends
the extension header
This patch finishes the new ipaccess_send_*() functions and use them
in the ipaccess-proxy code.
I have also cleanup the definition of the PONG, ID_ACK and ID_REQ
messages (including some minor documentation about them).
I had to rename ipaccess_recvmsg() in ipaccess-proxy to avoid clashing
with the one defined in libabis.
This patch extends the make_sock() prototype so you can fully set
the fields priv_nr and data of the bsc_fd structure.
This is the first step to get rid of the internal make_sock()
implementation that ipaccess-proxy uses.
This patch includes a minor cleanup to pass INADDR_ANY instead
of zero, if you do not want to bind the socket to one specific
address.
libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]

It seems HSL has fixed most of their obvious issues in the SR1.0.1
release. However, this creates quite an incompatibility of the
protocol, and we have to adapt accordingly
The HSL Femtocell seems to be a poor man implementation of the
ip.access Abis/IP protocol, but cutting corners wherever possible.
We try to workaround those corners wherever possible...
