Here is some heads up about v3.0.0. I had issue with it. I use openswan for a VPN connection as described here:

IPSec will only be established with the VPN gateway if I do use IPSec transport mode.

With v3.0.0, I have this error msg when doing: ipsec auto --up L2TP-PSK

003 "L2TP-PSK" #3: NAT-Traversal: Transport Mode not allowed due to security concerns -- using Tunnel mode. Rebuild Openswan with USE_NAT_TRAVERSAL_TRANSPORT_MODE=true in to support transport mode.

I did try to recompile by following the warning message but it doesn't change anything.

I have tried to grep the source code to see where this define was used and it doesn't seem to be used anywhere except in the error text msg.

So IOW, as of right now, 3.0.0 appears broken for my application of it.

Please consider pulling my fix on the next update. Upstream has merged it, although it not in any release yet.

Edit: fix has been included in

You may want to include Otherwise "self-proposal" errors may occur as seen in

Could you support aarch64?

I successfully compiled for this architecture by adding aarch64 to arch in PKGINFO.

Thank you

The package does not build on gcc 10-1. A workaround is to downgrade to gcc 9.2 and then build it.

$ yay -S downgrade # downgrade gcc gcc-libs

There are also issues with xmlto, is better to remove it: # pacman -R xmlto

One of the makefiles tries to remove a real system file during packaging. Non-root builds where a version is already installed barf. root builds would silently remove the file. This will fix it

This package is missing the following build dependencies:

  • inetutils (hostname command used during build)
  • xmlto (used to generate man pages)
  • docbook-xsl (required to have xmlto working correctly)

The "normal" diff format isn't very good. It won't apply if everything isn't exact. The context and unified will apply. Unified are the easiest to read.

Subtracting 1 isn't enough. That may shut the compiler up but it will earn us a CVE. strncpy() does not guarantee a nul end of string. The referenced patch has a decent way to guarantee a nul but I like my way better because it also guarantees no random text can appear after the nul.

The real answer is to write a custom strncpy() that has all the behavior we want, guaranteed nul and all nul to end of buffer.

I have the same issue when I copy/paste it from my comment.

Here is base64 version to avoid that as I don't know how to share it in a proper way.
