Subject: [PATCH] pppd: Use openssl for the DES instead of the libcrypt / glibc
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
It seems the latest glibc (in Fedora glibc-2.27.9000-12.fc29) dropped
|
|
libcrypt. The libxcrypt standalone package can be used instead, but
|
|
it dropped the old setkey/encrypt API which ppp uses for DES. There
|
|
is support for using openssl in pppcrypt.c, but it contains typos
|
|
preventing it from compiling and seems to be written for an ancient
|
|
openssl version.
|
|
|
|
This updates the code to use current openssl.
