Hi Jean-Christophe,

Interesting.  I can see how that would be useful rather than having to 
modify the dhcp server configuration when you want to use an alternate 
server.

Critique: the help is misleading: "host ip addr:" is optional so it 
needs another set of [] around it.  Having spaces in "host ip addr" is 
more readable, but makes it look like it is three things or perhaps a 
keyword.

I would suggest the following, but there may be a better way...
	"[loadAddress] [[hostIPaddr:]bootfilename]\n"

Best regards,
gvb

Sorry for being a PITA, but since we're changing documentation shouldn't 
this be:

-	"[loadAddress] [host ip addr:bootfilename]\n"
+	"[loadAddress] [[host ip addr:]bootfilename]\n"


Can you spot the difference?

Ben

You're not a PITA, but a careful reader.

Indeed - it's the difference between right and wrong, between working
and failing.

Also, I ask to change this (as gvb previously recommended) into

	"[loadAddress] [[HostIpAddr:]bootfilename]\n"

Doesn't this mean that TftpServerIP will be undefined if no server is

NAK.

Ben, please don't apply. I reject this patch.

Jean-Christophe - as already discussed on IRC I really ask you to pay
attemtion to gvb's comments on your patch:

| Critique: the help is misleading: "host ip addr:" is optional so it 
| needs another set of [] around it.  Having spaces in "host ip addr" is 
| more readable, but makes it look like it is three things or perhaps a 
| keyword.
| 
| I would suggest the following, but there may be a better way...
| 	"[loadAddress] [[hostIPaddr:]bootfilename]\n"

Also make sure that you place the ';' in the right pair of brackets.

Best regards,

Wolfgang Denk

Problem #1. First time through, with patch. Doesn't use serverip, so no

My 2c is that we go with 128, and have a CONFIG_LONG_TFTP_FILE_NAME that 
allows 1k for people with ridiculously long paths.

Blank line after declarations. And make this:

		char *p = strchr (BootFile, ':');

> +		if (p != NULL) {

Please swap the "if" and "else" branches and use "if (p == NULL)"


> +			TftpServerIP = string_to_ip (BootFile);

Note that there is no terminating '0' at *p ! You might want to insert
one for robustness.

Couldn't this be done as follows instead? This way there is no need to allocate any more 
memory on the stack, and no need for a new configuration option.

This is nice, because it works in-place and doesn't need the second 
buffer. One concern, though (see below)

I don't know if string_to_ip() works properly on a string of the format 
a.b.c.d:filename

Alternatively:

	char *p = strchr(Bootfile, ':');
	if (p && *(p+1) != '\0') {
		tftp_filename = P + 1;
		*p = '\0';
		TftpServerIP = string_to_ip(Bootfile);
	} else
		tftp_filename = Bootfile;

Andren,
	At least add my Signed-off
