Yes: udev on /dev type devtmpfs (rw,nosuid,noexec,relatime,size=8021332k,nr_inodes=2005333,mode=755,inode64) but this is how udev mounts it by default. Now I did: # mount /dev -o remount,exec and I got udev on /dev type devtmpfs (rw,nosuid,relatime,size=8021332k,nr_inodes=2005333,mode=755,inode64) and now it fails differently: 0x0000000000000000 0x0000000000002000 0x03 0x0000000000002000 0x0000000000001000 0x05 0x0000000000003000 0x0000000000003000 0x03 encl_load: encl->nr_segments: 3 encl_load: seg2 offset: 0x3000, seg2 size: 12288 encl_load: encl_size: 32768, src_size: 24576 encl_map_area: encl_size: 32768 encl_map_area: area: 0x0x7feae0db2000 encl_map_area: encl_base: 0x7feae0db8000 SGX_IOC_ENCLAVE_INIT failed: errno=1 -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
