This extra socket cause the EFI udp stack to duplicate every packet to be able to provide them to both udp_reader and socket->net.efi.binding. The ones in socket->net.efi.binding were never read so they accumulated in the stack on EFI side making the stack slower and slower. Slow enough to not be able to download a kernel+initramfs before the EFI timeout (5 minutes). Signed-off-by: Julien Viard de Galbe...

When attempting to build syslinux in parallel (make -j5), I encountered the following error at the end: rm -f liblpxelinux.a ar cq liblpxelinux.a rawcon.o ./fs/pxe/dhcp_option.o ./fs/pxe/pxe.o ./fs/pxe/tftp.o ./fs/pxe/urlparse.o ./lwip/src/netif/ethernetif.o ./lwip/src/netif/etharp.o ./lwip/src/netif/slipif.o ./lwip/src/netif/ppp/md5.o ./lwip/src/netif/ppp/randm.o ./lwip/src/netif/ppp/chpms.o

The variable 'ok' is never used and generates a warning. Remove it. Also ntfssect.c is designed to be compiled in non Unicode mode when using MSVC compilers, so remove all ambiguity about it (LPCTSTR -> LPCSTR, use of 'A' API calls) so that it doesn't break when compiled in Unicode mode, which is what Rufus uses with MSVC. -------------- next part --------------

...this a few years back: There are other issues with PXE over UEFI with syslinux. I got it to work by using version 6.04_pre1 plus 3 pathes and building from source: efi-udp-core_udp_connect-use-SubnetMask-not-StationA.patch efi-udp-Add-retry-disabling-UseDefaultAddress.patch efi-udp-Removing-the-udp_reader-efi_binding.patch Patches are cherry-picked commits from syslinux git tree. Fixes the decaying TFTP transfer rate problem. --jzb

I did change both instances of txdata->GatewayAddress, but I think something may be wrong in my toolchain. If I extract syslinux.zip and attempt to make from there (without modifying any files), the cached DHCP packet isn't read on the same subnet. I receive "Succeed to download NBP file." twice before anything from syslinux is loaded, so I believe the duplicate request for

Hi Guys, i have a problem with PXE/UEFI Boot. Legacy PXE Boot is working fine. I use Dnsmasq with integrated tftp. As Mentioned above, legacy pxe boot is working fine, tcpdump shows: --- start tcpdump legacy pxe boot --- 13:44:16.589197 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from f8:ca:b8:06:7d:ed (oui Unknown), length 548 13:44:20.543910 IP 0.0.0.0.bootpc >
