bfa0358a52 mqtt: Allow setting server port to connect
This is a mqtt client, so it does not make sense to determinate the server port
at compile time. Update mqtt_client_connect() function to allow setting server
port.

71810d0415 ipv6: adjust MLD membership on address state changes
If MLD support is enabled, each locally assigned IPv6 address in the
appropriate state must be a member of the solicited-node multicast
group corresponding to that address.  Ensure that this is always the
case by (re-)deciding on the membership upon every address state
change.  By doing so, this patch enforces that user-initiated state
changes to addresses (e.g., deletion) never cause a desynchronization
with the corresponding solicited-node multicast group membership,
thereby making such user-initiated state changes simpler and safer.

cceea73c3f bug #49631: handle zero-window probe and refused_data
This commit adds support for responding to a zero-window probe when
the refused_data pointer is set

A zero-window probe is a data segment received when rcv_ann_wnd
is 0. This corrects a standards violation where LwIP would not
respond to a zero-window probe with its current ACK value (RCV.NXT)
when it has refused data, thus leading to the probing TCP closing
out the connection

62e340067e LWIP_HOOK_TCP_ISN: added CHANGELOG/fixed comment 2016-12-15 21:08:12 +01:00
David van Moolenbroek
a8b986bbb6 Add hook for TCP Initial Sequence Number generation
lwIP produces a TCP Initial Sequence Number (ISN) for each new TCP
connection. The current algorithm is simple and predictable however.
The result is that lwIP TCP connections may be the target of TCP
spoofing attacks.  The problem of such attacks is well known, and a
recommended ISN generation algorithm is standardized in RFC 6528.
This algorithm requires a high-resolution timer and cryptographic
hashing function, though.  The implementation (or best-effort
approximation) of both of these aspects is well beyond the scope of
lwIP itself.

For that reason, this patch adds LWIP_HOOK_TCP_ISN, a hook that
allows each platform to implement its own ISN generation using
locally available means.  The hook provides full flexibility, in
that the hook may generate anything from a simple random number
(by being set to LWIP_RAND()) to a full RFC 6528 implementation.

Implementation note:

Users of the hook would typically declare the function prototype of
the hook function in arch/cc.h, as this is the last place where such
prototypes can be supplied.  However, at that point, the ip_addr_t
type has not yet been defined.  For that reason, this patch removes
the leading underscore from "struct _ip_addr", so that a prototype
of the hook function can use "struct ip_addr" instead of "ip_addr_t".
