Folks,
I've just released the first prelease for the 5.10 series. The intention
is to leave 5.02-pre3 where it is and move to 5.10-pre1. The only
difference between 5.02-pre3 and 5.10-pre1 is the merge of the lwip
branch (and a single commit to fixup the -DDEBUG=2 build), which
warranted a bump in the version minor number. See the shortlog below for
details of the differences between 5.02-pre3 and 5.10-pre1.
I don't expect people to be crying out for a 5.02 final release, but if
that is something that people want we can always do it retroactively at
any time. That isn't a problem.
With Syslinux-5.10-pre1 we've now got two network stacks; the old legacy
stack which is a very thin layer around the PXE interface, and the new
lwIP TCP/IP stack. The easiest way to include both of these stacks in
Syslinux was to build two separate .0 files, pxelinux.0 for the legacy
stack and lpxelinux.0 for the lwIP stack. Note there are no plans to
make the new http/ftp code work with the legacy stack, it's mainly being
kept around as a known reference point for when bugs are suspected in
lpxelinux.0 and because it is known to work with some rather quirky PXE
implementations.

[syslinux] Syslinux-5.10-pre1 looks for ldlinux.c32 in TFTP instead of HTTP
Hi,
got some problems.
I'm trying to use Syslinux 5.10-pre1 to see if it fixes a problem
described earlier.
First of a litle description how my System boots pxelinux.
DHCP Server looks if iPXE is allready loaded, and if not loads
ipxe.kkpxe (because of the cached DHCP reply) from TFTP.
When iPXE boots it's useing the cached DHCP request and boots pxelinux.0
from HTTP server.
Here is where the problem occours.
pxelinux.0 get's loaded from HTTP with no problems, but then pxelinux.0
tries to load the missing modules (in this case ldlinux.c32), but it
doesn't even try to load it from the HTTP server, but tries the TFTP
server where the iPXE gets chainloaded from.
Here is the config file embedded into iPXE:
#!ipxe
prompt --key 0x02 --timeout 1000 Press Ctrl-B for the iPXE command
line... && shell ||
set use-cached 1
dhcp net0
set 209:string http://***.***.***.187/pxelinux.cfg/default
set 210:string http://***.***.***.187/
set filename http://***.***.***.187/pxelinux.0
chain ${filename} ||
echo Netboot failed. Dropping to Shell...
shell
As you can see, everything is set to HTTP and i have no clue, why
pxelinux.0 tries to load it from TFTP anyways.

I just renamed lpxelinux.0 to pxelinux.0 because i was to lazy to recompile iPXE. But i tired if the nameing makes any difference. No effect sadly.

That means only UDP packets are available, not TCP, and not even raw IP packets on which one can build a TCP stack. We could do something better than TFTP, but it would have to be a new protocol run on top of UDP. Looking forward, however: EFI *does* provide a TCP stack, and so the high-level protocols introduced in this release can be used on top of the EFI stack directly. -hpa
