This may seem like overkill for a mere const char * config item, but it makes
the Control interface VTY commands reusable in any main() scope (inspired by
libosmo-abis' VTY config).
Add API functions ctrl_vty_init() and ctrl_vty_get_bind_addr(), in new files
src/ctrl/control_vty.c and include/osmocom/ctrl/control_vty.h, compiled and/or
installed dependent on ENABLE_VTY.
Using these functions allows configuring a static const char* with the VTY
commands
ctrl
bind A.B.C.D
which callers shall subsequently use to bind the Control interface to a
specific local interface address, by passing the return value of
ctrl_vty_get_bind_addr() to control_interface_setup().
Add CTRL_NODE to enum node_type, "eating" RESERVED4_NODE to heed that comment
on avoiding ABI changes.

|
|
|
|
|
| |
Make the ctrl interface bind address configurable, so that it may be made
available on other addresses than 127.0.0.1. The specific aim is to allow
running multiple osmo-nitbs alongside each other (commits in openbsc follow).

Add VTY command
line vty
bind A.B.C.D
The command merely stores the configured IP-address, which can then be used by
the calling main program to set the telnet port of the VTY line. (Commits in
openbsc and osmo-iuh will follow up on this.)
Add function vty_get_bind_addr() to publish the address in the vty.h API.
Add static vty_bind_addr to store.
For allocation/freeing reasons, a NULL address defaults to 127.0.0.1.
BTW, I decided against allowing keywords 'any' and 'localhost' in place of an
actual IP address to make sure a written config is always identical to the
parsed config.

This function originates from openbsc/src/gprs but is just specific
to BSSGP/Gb on the same level like bssgp_msgb_alloc.
This commit puts the former gprs_msgb_copy function beside
bssgp_msgb_alloc.
Renamed function:
gprs_msgb_copy -> bssgp_msgb_copy

Add bit map encoder and decoder functions: decoder is fully functional
while encoder is good enough for testing - no backtracking to find
the best possible compression is implemented. If somebody is willing to
implement MS side of EDGE than this has to be expanded.
Add corresponding tests.
N. B: the encoding is implemented according to ETSI TS 44.060 which is
slightly different from T4 used for fax according to CCITT G31D (RFC 804).

bitvec_read_field/bitvec_write_field in the PCU used a C++ reference
and when porting to C it was decided to pass the parameter by value
and this lost the "back propagation" of the new index. Change the
parameter to be an in/out parameter and this way do not have a silent
semantic break in the osmo-pcu (where we copy the reference in csn.1
by value) and have a true compile failure.
Add Max's simple test for bitvec_unhex function leaving the checking
of bitvec_read_field and the side effect in the datastructure about
the number of bits still open.

The undefined behavior sanitizer found the 32bit load from an
unaligned memory address. This will cause an exception on ARMv5te
and a manual fix-up.
[hfreyther: On armv6, x86 the usage of memcpy leads to shorter
amount of instructions but on armv5te the memcpy is not expanded
leading to a branch. Use the version of max until we have the time

The new functions bitvec_get_bytes and bitvec_set_bytes copy
byte sequences from bitvecs to uint8_t arrays and vice versa.
While the bytes in the bitvecs do not need to be aligned, the uint8_t
arrays always are. In case the bytes in the bitvec are aligned, the
implementation uses memcpy.
Note that the implementation like the other existing functions assume
MSB first encoding.

These functions originate from openbsc/src/gprs but are generic
msgb helper functions.
msgb_copy: This function allocates a new msgb, copies the data
buffer of msg, and adjusts the pointers (incl. l1h-l4h)
accordingly.
msgb_resize_area:
This resizes a sub area of the msgb data and adjusts the
pointers (incl. l1h-l4h) accordingly.

Currently the state is assumed to remain the same while the reset
procedure is active. While this works correctly in general, a single
unexpected BLOCK_ACK or UNBLOCK_ACK can change the state but will not
stop the reset procedure. The leads to repeated RESET messages, where
the corresponding RESET_ACK is ignored. This is a stable state which
can only be left by manual intervention or by reception of a RESET
message from the peer.
This commit changes the RESET timeout handler to set the state to
BLOCKED/RESET when sending the new NS RESET message.
Note that this should ensure a clean restart even if the state has been
screwed up. It does not fix the handling of BLOCK_ACK or UNBLOCK_ACK
in abnormal cases.

Currently the reporter loop is aborted, if the event would be ignored
due to an insufficient max_level. Thus the reporters that happen to
be stored afterwards would be skipped even if their level were
sufficient.
This commit replaces the conditional 'return' statement by a
considtional 'continue' statement to ensure the processing of the
list tail.

Currently only counter changes and new item values are being
reported. This makes it cumbersome to configure reporting clients,
since there is nothing like a list of all parameters.
This commit changes this behaviour such that all currently existing
counters and items that would be reported eventually, are passed to
the reporter when it has been reconfigured or enabled. If a counter
has not been incremented, 0 is sent. If a stat item value has not
been added, the last item value (or the default value if there is
none) is resent again.
Note that this will not catch transient counters/items that will be
created later on, e.g. triggered by new peers or subscribers.
To just force this kind of dump on a running reporter, it is
sufficient to invoke the 'enable' command in its configuration node.

Currently the having an unset prefix leads to an abort() in the
statsd reporter due to an fprintf format string error. In addition
the prefix cannot be reset to its initial state (NULL) by using 'no
prefix', which just sets the prefix to the empty string, causing a
single leading dot to appear in front of the name.
This commit changes the implemenation to consistly use NULL for
the unset name prefix ('no prefix') and to handle this case correctly
in the statsd reporter.

The NS object is created with an unknown identity and only after
the reset procedure has progressed (completed?) we know the real
ID for this peer. Before nobody has looked at the idx values (this
could have been seen with the CTRL interface) but with statsd the
wrong NSVCI becomes obvious.
Add routines to update the idx and I don't know if the change of
idx is causing any issues but we will find that out soon.
