Modify the osmo_sock_init (code clone to be integrated upstream)
to allow binding to a specific source ip and source port. Allow
the source ip to be configured but allow the kernel to pick a
random port for us.
This is necessary for systems with multiple interfaces where the
default route is not necessarily the right one to connect to the
pcap server.

When not running as root the opening might fail and then we would
crash when sending the link information. Do not crash. This could
have crashed before the re-factoring but due the async connect it
seems more likely we hit it now.

With the VTY a user can write connect, connect, connect and this
would lead to leaking fds. Always close the connection.

Allow to configure multiple servers and connect. Introduce a new VTY
node to allow multiple servers. Add an explicit connect. Do not put
the main connection into the same list but assume it exists.

If we want to have multiple servers we should not block when trying to
connect to one of them. Enable non blocking mode and handle the fd
specially until it is connected. E.g. on failed connect the read will
become readable but fail, otherwise it becomes writable.
Clear the write queue to make sure that the link data is sent first.
We might be able to introduce a osmo_wqueue_prepend.

There is no VTY code yet and no servers in the list but it looks
good client this.

Take out various fields into a new connection class. We will have the
option to connect to multiple servers.

Add simple vty command to enable tls per client or not. We still
need a lot more tls commands for the server.

Using tls priority of NORMAL:+ANON-ECDH:+ANON-DH already allows a
client to connect to a server and protect the data using tls.
Generate the dh params on load (and do that for the client right
now as well) but that will go away soon.

In preparation of TLS let's not call close_connection from
within the dispatch but return an error and then close the
connection from the outside.

We are only reading from the socket and never write but the osmo_tls
code is integrated with it. We will never write and the queue size is
set to 0. Simplify the read_cb.

Use GNUtls because it is GPL compatible and instead of mbedTLS seems
to have a working non-blocking I/O integration. GNUtls has various
issues that could not be resolved easily:
* Pick spdy as sub protocol
* gmt_time not randomized
* private key loaded to RAM (but not verified)
This is the beginning and not the end. Client support might need more
work with actual tls verification. Maybe more manual x509 cert
verification is needed and maybe client certs don't work at all. I try
to ignore renegotiation as I threw away the key.
Reload x509 creds and keys as they might have changed from one
connection to another.

Add the basics for getting a picture what a client and the server
is doing. We need to create unique descriptions as the code is
working with names and not numbers for clients.

To allow easily extracting or streaming the data to an external
analysis system, zeromq can be configured (and reconfigured). The
system works as fire and forget and no loss detection is present.
A simple go based client application is provided to subscribe to
the publisher.

We might only want to centralize the data streams but handle the
data differently. This will be combined with an upcoming ZeroMQ
publisher feature to broadcast all events out.

We need to convert the 64bit timeval on a 64bit userspace (or on
OpenBSD) into a 32bit truncated value for being able to write the
file. This means we have 2038 issue here?
|
|
Check the caplen and see if it is bigger than our assumed
maximum. Make sure we have enough space for data+hdr+hdr.
|
|
The 2000 as a number is too small. Modern networks can have a
higher MTU (up to 9000). Take this number and assume there is
a big header in front of it.

These generate a high amount of traffic. They are good to debug
ip.access nanoBTS GPRS crashes/service outage but in general cause
too much traffic.

These variables were used to verify how many LLC frames were
seen.
|

Allow to inspect UDP messages and check for GPRS, NS, BSSGP
and then filter LLC frames. Parsing the vL datastructure with
the libpcap syntax is a pain. It could be done using BPF but
we do not want to use bpf asm to specify the entire ruleset.
I looked into using libepan/libwireshark but this has memory
issues and is painful too. So let's parse UDP, NS, BSSGP using
the info we already have. I tried a bit of editcap to generate
a bit of broken data. The length check might still be bad.
I used my crash_20100602.pcap file to count the LLC frames we
detect and compare that to wireshark it ended with the right
number.
pcap add-filter gprs
can be used to enable the new filtering option after the OS
has received the packet.

This is fixing:
src/osmo_client_core.c +105 osmo_client_capture(8) warn: variable dereferenced before check 'client'
|
|
|

The connect0_bind1 parameter has been replaced by a generic flag
parameter. With this patch osmo-pcap works (only) with versions of
libosmocore 0.3.2 or newer - configure.ac changed to reflects that.
