[lwip-devel] [bug #28049] Keep Alive timeout frees pcb then uses it, sometimes causing crash error.

[Simon Goldschmidt]

Update of bug #28049 (project lwip):

                  Status:                    None => Need Info

Follow-up Comment #1:

The fix would be OK, but I think we might rather change the code to not call
tcp_abort at that place:

The keepalive timer is the only timer inside tcp_slowtmr calling tcp_abort,
all other timers increase pcb_remove. The difference is mainly that by this,
the keepalive timer send directly sends a RST when expiring while the other
timers don't.

Is there a reason for this? Kieran maybe?

This is a fairly old bug (has been in there since 1.32 from 6 years ago...).
