Hi all,
When using Busybox tftpd as a tftp server in combination with the RedBoot
tftp client, I got a "malformed packet" response to every request.
The reason is that RedBoot requests "OCTET" mode in upper case, where
Busybox only checks for the lower case "octet" mode variant.
The tftp RFC 1350 states: "The mode field contains the
string "netascii", "octet", or "mail" (or any combination of upper
and lower case, such as "NETASCII", NetAscii", etc.) in netascii
indicating the three modes defined in the protocol.
Therefore I suggest to change busybox-1.19.0/networking/tftp.c line 816:
- if (mode >= block_buf + result || strcmp(mode, "octet") != 0) {
+ if (mode >= block_buf + result || strcasecmp(mode, "octet") != 0) {
I'm new to suggesting patches etc., so if more information is needed, please
ask.
Thanks,
Brecht
