perl-IO-Socket-SSL/IO-Socket-SSL-2.039-use-system-default-SSL-version.patch
Paul Howarth 48b55376ef Update to 2.039
- New upstream release 2.039
  - OpenSSL 1.1.0c changed the behavior of SSL_read so that it now returns -1
    on EOF without proper SSL shutdown; since it looks like that this behavior
    will be kept at least for 1.1.1+, adapt to the changed API by treating
    errno=NOERR on SSL_ERROR_SYSCALL as EOF
- Update patches as needed
