This is the first ppp release for years, and the project appears to have a different maintainer (team?) by now. As a result, some of our patches are no longer necessary as they made it into upstream, while others need to be adjusted slightly.
In addition, their configure script does not handle commas in CFLAGS properly, which is why the delimiter for the 'sed' call in it has to be changed to something neither appearing in a path nor in our CLFAGS set.
The full changelog of this release can be retrieved from https://ppp.samba.org/README.html and says:
* Support for new EAP (Extensible Authentication Protocol) methods: - Support for EAP-TLS, from Jan Just Keijser and others - Support for EAP-MSCHAPv2, from Eivind Næss, Thomas Omerzu, Tijs Van Buggenhout and others
* New pppd options: - chap-timeout - chapms-strip-domain - replacedefaultroute - noreplacedefaultroute - ipv6cp-accept-remote - lcp-echo-adaptive - ip-up-script - ip-down-script - ca - capath - cert - key - crl-dir - crl - max-tls-version - need-peer-eap
* Fixes for CVE-2020-8597 and CVE-2015-3310.
* libpcap is now required when compiling on Linux (previously, if libpcap was not present, pppd would be compiled without packet filtering support).
* The rp-pppoe plugin has been renamed to pppoe, to distinguish it from the upstream rp-pppoe code. Its options have changed names, but the old names are kept as aliases.
* The configure script now supports cross-compilation.
* Many bug fixes and cleanups.
Thanks to Michael for his hint on the ./configure CFLAGS issue.
