[syslinux] [PATCH 2/5] ntfs: remove unused variable and have ntfssect use char API calls
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 --------------

I seem to recall warnings about > unused results, but not of unused objects. Maybe that's an incorrect > recollection or maybe it's ancient history, however.I got no warnings with the patch on Debian 8 + MinGW-w64.

Hi guys,
I have re-implemented /efi/udp.c
The new code fixes:
1) The low and decreasing throughput on TFTP transfers.
2) The added delay between consecutive TFTP transfers.
3) The TFTP errors induced by broadcast traffic like ARP.
Initial tests on a 50MB transfer showed times going from 3 minutes
to ~12 seconds, also tested OK with nested TFTP transfers
(include command).
This new code affects/fixes the problems reported at:
a) "Problem with 90MB Initrd"
http://www.syslinux.org/archives/2015-September/024236.html
b) "UEFI: Failed to load ldlinux.e64/ldlinux.e32"
http://www.syslinux.org/archives/2015-October/024341.html
This report has led to Gene's patch:
https://github.com/geneC/syslinux/commit/9e0926bb338deb5c634ccb4ee29eb4577158cfdc
it was reported working but I think "it cannot work" if it has these
lines
+ memcpy(&udata.StationAddress, &IPInfo.myip, sizeof(IPInfo.myip));
+ memcpy(&udata.StationAddress, &IPInfo.netmask,
sizeof(IPInfo.netmask));
the StationAddress gets overwritten by a netmask...
There's a picture attached comparing performance between the old and new
udp.c code.
Testing reports are welcome.
Best,
Patrick
