[syslinux] Syslinux 4.10-pre20

I think I finally have nailed down the problems with TFTP on the 4.10
branch, and so I have released 4.10-pre20.

Please let me know if you have hardware on which 4.05/4.06-pre3 works,
and 4.10-pre20 does not.

Hi,

No joy here ... doesn't work on my real HW setup.
Also doesn't work on my KVM virtualization setup.
I am using dnsmasq as the TFTP server.

1) Real hardware experiment:
The client machine; gets stuck at the following line:

--- client ---
TFTP prefix:
Trying to load: pxelinux.cfg/44454c4c-4200-1037-8038-c2c04f343253
--- client ---

--- server ---
Meanwhile on the TFTP server side I see the following messages ... continuously
...

dnsmasq-tftp[11244]: file
/tftpboot/pxelinux.cfg/44454c4c-4200-1037-8038-c2c04f343253 not found
dnsmasq-tftp[11244]: file
/tftpboot/pxelinux.cfg/44454c4c-4200-1037-8038-c2c04f343253 not found
dnsmasq-tftp[11244]: file
/tftpboot/pxelinux.cfg/44454c4c-4200-1037-8038-c2c04f343253 not found
......
--- server ---

If I create a symlink named "44454c4c-4200-1037-8038-c2c04f343253" to
the file "default", then
all I see on the client side is an extra "ok", but client is still
stuck!!!
--- client ---
Trying to load: pxelinux.cfg/44454c4c-4200-1037-8038-c2c04f343253 ok
--- client ---

... and on the server side I get continuous messages ...
--- server ---
failed sending /tftpboot/pxelinux.cfg/44454c4c-4200-1037-8038-c2c04f343253 to

failed sending /tftpboot/pxelinux.cfg/44454c4c-4200-1037-8038-c2c04f343253 to
XXX
...
--- server ---


2) virtualization experiment

I have a ProxMox based server with a kvm guest.
ProxMox uses the iPXE roms to provide "network booting" capabilities
to the guest VM

With 4.10-pre20, what happens is that the file request NEVER goes from 
the "mac-address-file" to "default" whereas it "just
works for 4.06-pre3

with 4.06-pre3:
dnsmasq-tftp[11244]: sent /tftpboot/pxelinux.0 to XXX
dnsmasq-tftp[11244]: file
/tftpboot/pxelinux.cfg/00000000-0000-0000-0000-000000000000 not found

dnsmasq-tftp[11244]: sent /tftpboot/syminstall.png to XXX

with 4.10-pre20
dnsmasq-tftp[11244]: sent /tftpboot/pxelinux.0 to XXX
dnsmasq-tftp[11244]: file /tftpboot/pxelinux.cfg/01-8a-f6-32-68-67-41 not found
(kvm guest reboots) :( :(
dnsmasq-dhcp[11244]: DHCPDISCOVER(eth0) 8a:f6:32:68:67:41
dnsmasq-dhcp[11244]: DHCPOFFER(eth0) XXX 8a:f6:32:68:67:41
dnsmasq-dhcp[11244]: DHCPREQUEST(eth0) XXX 8a:f6:32:68:67:41
dnsmasq-dhcp[11244]: DHCPACK(eth0) XXX 8a:f6:32:68:67:41 XXX
dnsmasq-dhcp[11244]: PXE(eth0) XXX 8a:f6:32:68:67:41 pxelinux.0
dnsmasq-tftp[11244]: sent /tftpboot/pxelinux.0 to XXX
dnsmasq-tftp[11244]: file /tftpboot/pxelinux.cfg/01-8a-f6-32-68-67-41 not found
(kvm guest reboots) :( :(

If I create a symlink named '01-8a-f6-32-68-67-41' to 'default'
then it does load the menu and everything
works after that (unlike the real hardware setup)

Shantanu

What is the *exact* printout when you boot the Optiplex 755 (I guess?)
in hardware mode?  Any way you can get a package capture?

Hi,
Any update on this? Does the traffic dump help? Is it even correct? (I am not
familiar with using tcpdump much)

Hi,
I had only now time to do some tests.
Unfortunally not successfull.
Tested with 4-10-pre20 and as reference with 4-05

1. Dell E4310 with Intel 82577LM / Boot Agent GE  1.3.52.1
hangs after
UNDI code segment at 95C9 len 4F00
UNDI code segment at 8F90 len 6390
4-05 was ok

2. Dell Optiplex 760
- embedded NIC Intel 82567LM-3 / Boot Agent GE  1.3.52.1
and
- extra NIC Intel PRO/100 S / Boot Agent 3.0.03
both hang after
Trying to load: pxelinux.cfg/aa-bb-cc-dd-ee-ff-gg-hh
4-05 was ok

a Dell E6500 with a Broadcom NIC did the job with 4-10pre20 and 4-05

bye
Christoph
