Follow-up Comment #5, bug #40363 (project grub): When the block number gets over 0xffff the last packet gets ack'ed twice and grub shows this error: error: not an IP. (Due to an tcpdump at the tftp server; the tftp server itself is logging that the file was sent successfully.) (With the patch #29471 tftp.diff applied on top of yesterdays git c16535a845dcbb2b1d3b42994d3b72b8dc088a38) I think this is because ack_sent stores only the 2 byte block number. When storing in ack_sent the real block number like in attached patch it works when the block number turns over. (And works also for smaller files.) (Tested indeed only in a tiny network with one VM as server, one VM and one PC as clients.) (file #29478) _______________________________________________________ Additional Item Attachment: File name: 0001-TFTP-Handle-overflow-in-blocknumber-fixes-bug-40363-try-4.patch Size:2 KB _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?40363> _______________________________________________ Nachricht gesendet von/durch Savannah http://savannah.gnu.org/
