[meta-oe][PATCH] cryptsetup: Update to latest version and use openssl as crypto backend

[meta-oe][PATCH] cryptsetup: Update to latest version and use openssl as crypto backend

[Stefan Herbrechtsmeier]

Cryptsetup with the command luksOpen failed with the error message:
device-mapper: status ioctl failed: Permission denied

The error comes from libgcrypt with drops root privileges if it is
linked with libcap support [1]. Update cryptsetup to latest version
and change the crypto backend to openssl as libgcrypt states this
behaviour as a feature [2].

The license was updated to GPLv2 with OpenSSL exception.

Should I then keep gcrypt as default or change it to openssl by default?

[meta-oe][PATCH V2] cryptsetup: Update to latest version and use openssl as crypto backend

[Stefan Herbrechtsmeier]

Cryptsetup with the command luksOpen failed with the error message:
device-mapper: status ioctl failed: Permission denied

The error comes from libgcrypt with drops root privileges if it is
linked with libcap support [1]. Update cryptsetup to latest version,
add PACKAGECONFIG for crypto backend selection (openssl / gcrypt)
and change the default crypto backend to openssl as libgcrypt states
the drop root privileges behaviour as a feature [2].

The license was updated to GPLv2 with OpenSSL exception.

Update the RRECOMMENDS to be conistent with the package names.
