Matthew Jordan (383878):

>Resolve deadlock between SIP registration and channel based functions
>
>In r373424, several reentrancy problems in chan_sip were addressed. As a
>result, the SIP channel driver is now properly locking the channel driver
>private information in certain operations that it wasn't previously. This
>exposed two latent problems either in register_verify or by functions called
>by register_verify. This includes:
> * Holding the private lock while calling sip_send_mwi_to_peer. This can create
>   a new sip_pvt via sip_alloc, which will obtain the channel container lock.
>   This is a locking inversion, as any channel related lock must be obtained
>   prior to obtaining the SIP channel technology private lock.
>
>   Note that this issue was already fixed in Asterisk 11.
>
> * Holding the private lock while calling sip_poke_peer. In the same vein as
>   sip_send_mwi_to_peer, sip_poke_peer can create a new SIP private, causing
>   the same locking inversion.
>
>Note that this locking inversion typically occured when CLI commands were run
>while a SIP REGISTER request was being processed, as many CLI commands (such
>as 'sip show channels', 'core show channels', etc.) have to obtain the channel
>container lock.
