b18dd41b2d net: ipv6: Clear pending buf if NS cannot be sent
If for some reason the neighbor solicitation cannot be sent,
then we need to unref the pending packet as that would never
be freed otherwise.

d6d1b3a748 net/mgmt: Add a network interface based synchronous event listener
In case of callback based event listener, it is easy for the callback to
filter on the given interface. But in case of the synchronous call it's
not: it would need, after a failed comparison on the interface pointer
to loop by itself on the net_mgmt_event_wait() which is a little bit
heavy (reinstalling the event listener, with the semaphore and all) and
a bit of a burden for the caller itself.

Instead, net_mgmt provides a dedicated call
net_mgmt_event_wait_on_iface() which does it the right way, so the
callback and the related semaphore are destroyed if only the iface
matches the one given as parameter (besides the timeout obviously).

35e5aa8865 net/mgmt: Add a function to wait on a event synchronously
Instead of creating a handler and a related callback structure on an
event_mask: net_mgmt_event_wait() can be used to wait synchronously on
such event_mask. The core mgmt part will seamlessly reuse the struct
net_mgmt_event_callback so the whole internal notification mechanism is
using the same code.

c1ecd8c890 net: context: For bind debug logging, include context protocol.
It's not enough to know just network address and port number to

Such switch has been first done in bluetooth (see hci_core.c and conn.c
in subsys/bluetooth/host). Since network interfaces kind of follows the
same design for sending data, it was then easy to copy the same change as

0453629078 net: ip: Fix 6lo buffer leak when sending ACK
Due to recent TCP fixes for 6lo, we are making a copy of buffers
sent to net_tcp_send_buf() so that TCP retransmit can send the original
(unmodified) buffer.  This original buffer is freed via the TCP
sent_list when the related ACK packet is received.

However, there are users of the net_tcp_send_buf() function which
will never get a corresponding ACK (and do not add the buffer to the
TCP sent_list).  An example is send_ack() in net_context.c.  In this
case, we leak the original buffer.

To fix this leak in the 6lo specific block of net_tcp_send_buf(),
let's check to see if the original buffer was added to the TCP sent_list
and if not, then avoid the buffer copy process entirely.

aa95a93f38 net: iface: Print error if we cannot join mcast groups
