[bug-inetutils] GNU inetutils-1.7 tftp not handle long file name bug

[王智通]

Hi, all:

In GNU inetutils-1.7/tftp/main.c:

char line[200];  // cmd line buffer only read 200 bytes, I think it’s too 
small, if a file name too long(like 256), the tftp client will display:

[r...@localhost tftp]# ls
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.c

tftp>put 
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.c
No such file or directory
tftp> ?Invalid command

the command() function only handle 200 bytes buffer:
static void
command ()
{
  register struct cmd *c;

  for (;;)
    {
      printf ("%s> ", prompt);
      if (fgets (line, sizeof line, stdin) == 0)
         {
           if (feof (stdin))
             exit (0);
           else
             continue;
         }
}

I think it’s a little bug, maybe the line variable will has a big buffer:)
