See strace below, splice() return -ENOKEY. The ENOKEY error is due to an accept() at the wrong location. But I do not see that error: tar xvfJ libkcapi-0.14.0.tar.xz cd libkcapi-0.14.0 autoreconf -i ./configure --enable-kcapi-hasher make cd bin/.libs/ # I make no make install for testing ln kcapi-hasher md5sum # create md5sum app export LD_LIBRARY_PATH=../../.libs/ # location of current library $ ./md5sum md5sum ddd1a82680b16fb6c241d81656b844df md5sum So, it works for me. Can you please check whether you use the current library version? Note, library version 0.10.1 fixed the aforementioned accept() call for kernel 4.4 and later. $ ./md5sum -v md5sum: libkcapi 0.14.0 Ciao Stephan
