2f293d53ba UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0, create checksum over the complete packet. On RX, if it's < 8 (and not 0), discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both UDP & UDP Lite. 2007-06-11 18:03:57 +00:00

974cf08e5d udp_input(): Input pbuf was not freed if pcb had no recv function registered, p->payload was modified without modifying p->len if sending icmp_dest_unreach() (had no negative effect but was definitively wrong). 2007-06-03 11:32:03 +00:00

2740a81103 If a udp_pcb has a local_ip set, check if it is the same as the one of the netif used for sending to prevent sending from old addresses after a netif address gets changed (partly fixes bug #3168). 2007-05-16 18:55:25 +00:00

5368a760cf most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with others environment defines (these were too "generic"). 2007-03-30 08:47:04 +00:00

7294cb080b * Fix all uses of pbuf_header to check the return value. In some
cases just assert if it fails as I'm not sure how to fix them, but
    this is no worse than before when they would carry on regardless
    of the failure.

e1b6a4cb21 udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"

6158aa684b udp_input() operated by removing the IP and UDP headers, putting back
the UDP header, then re-removing it.  However, pbuf_header() can't add
back the UDP header on pbufs of type PBUF_REF, so these would all get
dropped for bad checksum.  This change addresses the problem and
simplifies things by stripping each header just once.
