It's been noticed that trying to print a zero
conneciton address, on the media stream, which
actually offered non-zeroed IP source, but a
zero port, leads to a segmentation fault,
because it relies in this case on presented
`sockaddr_t` information, which is actually absent.
This happens only with sdp_create on offer/answer.
Test fixed is "a=mid on zero streams".

Look for the first usable (non-rejected, non-empty)
media and ps, thereby to determine session-level attributes,
if any. For that to work, it has to have `->selected_sfd`
of the packet stream.

Instead of having to explicitly pass the call object to each invocation,

For the `print_sdp_media_section()` change
parameter naming `message_setup` -> `sdp_create`,
so that other differentiations can also take place
in this function.
E.g. slightly different rtcp handling for the
sdp_create in comparison to the sdp_replace (because
no chopper based approach can be applied here).
Change-Id: I555e0ace04b384d6907f831c2a3de9a0b09777e4
Support session level group attribute
for the sdp_create approach.

Don't just set always to true (if media is active),
but check if it's a MESSAGE type, which is by default
inactive.
Change-Id: I492e6fb62acb6fb6a112353535171a22e93baf3f
For the `sdp_create` based approach, introduce
`a=setup:` handling in cases with the message media
type processing.
Currently this has to be divided for sdp_replace
and sdp_create users. This is because sdp_replace one
uses chopper based approach, which in combination with
changes in this commit dupplicates the setup attribute.
In order to separate the logic both approaches,
introduce a temporary bool, until the time when
sdp_replace gets fully deprecated.
A move of the check out of the `is_active` condition
is required, because the message media type isn't active
and hence has to be checked out of the active context.
Change-Id: I32b8f3f3928ba22e030ab5a6414b93fcd7c47201
Just keep the `s=` attribute empty, if it is

Current behavior of the sdp_create approach just
inserts the `rtpe_config.software_id`, which is wrong.

Even if the media isn't accepted, still check for the mid

Change-Id: Ib92930d6e1ec4dfe526fa18869c5f7a8e17f6a4f
Move handling of the usual `m=` line, so printing
of: media type, port, protocol (e.g. RTP/SAVP),

This function is a default alternative for the

Change-Id: I147403ff9e3c3ff8be6718b8b118e405442a9220
In case when the `packet_stream`, selected via the
media being iterated, has no `->selected_sfd`,
just set the port value to 0.
Also skip adding any further attributes, like
connection information or any other, since
this media by fact is not accepted.
This is a usecase for OSRTP related scenarios,
where RTP media session can have 0 port set.
Change-Id: I7784b80e7d51d19106ea30db585143375a5ba050
Move printing of attributes to a separate func,
in order to be able to re-use this print during
the same media section iteration (e.g. with OSRTP).
Later on this func is to be merged with the
`print_sdp_media_section()` function, after
the sdp_replace is fully deprecated.
Change-Id: I15825ed6eecb450b742b31677961fd8ddbf950fb

Same as ptime but for the maxptime.

Add support of replacements flags:
- replace-origin
- replace-origin-username
- replace-origin-full
Additionally: fix websocket tests, because now
the `-` symbol isn't considered as the one to be
set always when using `replce-origin-full`.
Instead it will use values of the very first parsed SDP.
Change-Id: I7636f020cb92cb760fcd25b0b84509e6d5ba2a9f
Set the `monologue->session_last_sdp_orig` not while
replacing in `sdp_replace()`, but while initializing the
monologue in `__call_monologue_init_from_flags()`.
This allows to be agnostic in relation to `sdp_replace()`,
and let the `monologue->session_last_sdp_orig` be always
actual for the `sdp_create()` related processing
(without a need to pull the SDP sessions list towards it).
Change-Id: Ideb129ab8a94ef750abfa222335aede42bcbcc89
The option flag `replace-origin-full` should replace whole
origin (o=) line of the SDP body, so that all origin fields
in the `o=` line always remain the same in all SDPs going to a
particular RTP endpoint.
So, not just a straight-forward replacing with own values.
A behavior in relation to the address field is the same
as by the `origin` option flag.
Correct according tests and add one more.
Change-Id: I4bcb740db5cd68a75fb754f5f6b5d21e19b05e1b
Use the `->session_last_sdp_orig` for the version as well as
username type of replacements.
Remove superfluous code.
It's possible to handle it like that, because the last user
of the sdp_replace func, which is the offer/answer model, sets
the `->session_sdp_orig` actually in `__call_monologue_init_from_flags`.
Additionally: add tests for the user type of the origin replacement.
Change-Id: Idd60e628c676840c2e844077303035c0edec67e2
Make the `sdp_replace()` compliant with `sdp_create()` in terms
of the replace `origin-full` flag support.
Also introduce according unit tests.
Change-Id: Ib950a957d5ee3820dbc8a831fe0a7ea570b4c59b
Two version of the origin replace exist from now on:
- `origin-replace` - replaces only the origin address
- `origin-replace-full` - replaces all the values,
so name, id, version and IP family with address.
Values for replacing are taken from the rtpengine instance,
so local values provided by the daemon.
Additionally: documentation updated accordingly.
Additionally: revert changes in pub-sub test.
Change-Id: I4d068944726d1ab82683ca5aa641a954890aefcf
Instead of using separate char arrays storing
parts of the SDP origin (in monologue), just
use the corresponding structure.
Deprecate unused parts used before.
Additionally add logic:
don't set `->session_sdp_orig` for monologues
with empty tags. This leads to setting origin line
to those monologues, which will later skip updating it
with its own (so real one).
This is fixes the case with the offer/answer model,
where offer always sets its origin for the other side,
meanwhile the other side hasn't given the answer yet.
Then later this answer related monologue never gets
its real origin.
For this sake also adopt logic of `sdp_version_check()`
which serves 'SDP-version' and 'force-increment-sdp-ver'
flags.
Change-Id: I17f3ff67e1b3dafca797c5feb876ebb238dceaa2
Instead of using separate data members to
bring data with the `call_monologue` structure,
just use the whole `sdp_origin` object type (structure)
as a pointer and keep it aling with real SDP origin
of according monologue's side.
Refactor the code accordingly for `sdp_create()`
users (firstly only here).
Additionally introduce functions to alloc/de-alloc
`sdp_orig` object:
- `sdp_orig_dup()` returns a pointer to copied object
- `sdp_orig_free()` deallocates it
Change-Id: Iff6a777e4867e78c73ca79c73fdb73ff8e9f22eb

Move the `call_subscribe_request_ng()` fully to a usage

Carry the origin IP and net family via flags
to the monologue, so can be reused later when creating SDP.
Always use given SDP session origin IP address and family
for the SDP being prepared, unless sdp origin replacement
is required via given flags (in this case just used
an advertised IP of rtpengine).
Additionally: fix unit tests for subscribe cases accordingly
to the policy.

- `sdp_media` -> `stream_params` in sdp_streams()
- `stream_params` -> `call_media` in ` __media_init_from_flags()`

This is because we seem to never actually take into account
presence of bandwidth data in offer/answer model preceding
the subscribe request.

being inserted into SDP. Previously not supported.
Additionally: `process_media_attributes()` takes new
argument `bool strip_attr_other`, in order to control
whether or not to strip `ATTR_OTHER/ATTR_SSRC/ATTR_MSID`.
For now there is only one user of it `replace_sdp_media_section()`,
but for later on, we can control this using this bool.
Additionally: `print_sdp_media_section()` takes new
argument `bool print_other_attrs`, in order to control
whether or not to strip `ATTR_OTHER/ATTR_SSRC/ATTR_MSID`.
This is required, because the sdp replacing/creating mechanism
needs a controllable way of adding them, users are:
- `janus_videoroom_join()`
`janus_videoroom_configure()` - always need them
- `call_publish_ng` - always needs them
- `call_subscribe_request_ng` - never needs them
(otherwise leads to a duplication of such attributes)
- `call_offer_answer_ng()` - requires them always
- `call_subscribe_request_ng()` - never needs them
(otherwise leads to a duplication of such attributes)

Move processing of removal and substitution
attribute manipulations to the bottom,
after all fixed (well known to rtpengine)
attributes are skipped already.
This is done for media and session level attributes:
- `process_media_attributes()`
- `process_session_attributes()`
This is to add an efficiency to the current processing,
and not do double work.
Change-Id: Idd933f9d85aef5e9a5d597f8825d21e45f43ef37
Add media attributes substitution support to
the following functions:
- `append_attr_to_gstring()`
- `append_attr_int_to_gstring()`
First functions check, if the attribute has to be
removed (by the manipulations profile), if not
then it checks out whether we have to substitute it.
If neither of manipulations have to be applied,
then the given attribute gets attached to the chopper.
This gives support of substitution for
such media level attributes like:
- `mid`
- `label`
- `ptime`
- `ice-ufrag`
- `ice-pwd`
- `ice-options`
etc.
