This resolves an `XXX' in ccid3_hc_tx_send_packet(). The function is only called on Data and DataAck packets and returns a negative result on zero-sized messages. This is a reasonable policy since CCID 3 is a congestion-control module and congestion control on zero-sized Data(Ack) packets is in a way pathological. The patch uses a more suitable error code for this case, it returns the Posix.1 code `EBADMSG' ("Not a data message") instead of `ENOTCONN'. As a result of ignoring zero-sized packets, a the condition for a warning "First packet is data" in ccid3_hc_tx_packet_sent is always satisfied; this message has been removed since it will always be printed.

This makes some logically equivalent simplifications, by replacing rc - values plus goto's with direct return statements. Signed-off-by:

This patch performs a simplifying (performance) optimisation: In each call of the inline function ccid3_calc_new_t_ipi(), the state is tested against TFRC_SSTATE_NO_FBACK. This is expensive when the function is called very often. A simpler solution, implemented by this patch, is to adapt the control flow. Background:

Ack vectors grow proportional to the window size. If an ack vector does not fit into a single option, it must be spread across multiple options. This patch will allow for windows to grow larger. Committer note: Simplified the patch a bit, original algorithm kept. Signed-off-by:

Commiter note: This was split from Andrea's original patch, in the process I changed the type of the ackvec index fields to u16 instead of to int and haven't folded dccp_ackvec_parse with dccp_ackvec_check_rcv_ackno. Next patch will actually do the insertion of more than one ackvec per packet, using, initially, up to a max of 2 ackvecs as per Andrea's original patch, then I'll work on support for larger ackvecs, be it using a sysctl or using setsockopt.

Extends the netlink interface to support the __le16 type and converts address addition, deletion and, dumping to use the new netlink interface. Fixes multiple occasions of possible illegal memory references due to not validated netlink attributes. Signed-off-by:

Allow link-local tunnel endpoints if the underlying link is defined. Signed-off-by:
-
Ville Nuorvala authored
Doing the mandatory tunnel endpoint checks when the tunnel is set up isn't enough as interfaces can go up or down and addresses can be added or deleted after this. The checks need to be done realtime when the tunnel is processing a packet. Signed-off-by:
