>Description:
A big file (more than 32MBytes) can not been downloaded/uploaded
whith the current TFTP client.
After sending/receiving the segment #65535, TFTP waits for the segment
#65536 which can not be produced, since TFTP protocol reserves only
2 bytes for packet number.
I have not checked if the TFTP server has the same limitation.
>How-To-Repeat:
Transfer a big file and use a correct TFTP server.
>Fix:
The following lines in the file /usr.bin/tftp/tftp.c should
include u_short cast :
165, 176, 269, 279
For instance
if (ap->th_block == (block-1)) {
should be fixed in
if (ap->th_block == (u_short) (block-1)) {
