Summary: This release adds support for AMD Radeon Vega 12 and it enables the "display code" by default in supported AMD Radeon GPUs; it also adds a kernel TLS receive path; a more efficient idle loop that prevent CPUs from spending too much time in shallow idle states; eight unmaintained architectures have been removed and another, the Andes NDS32. > vhost_vsock. The VFIFO/VSOCK code, which is why "struct fileops" is used at all, is an artifact of an incomplete integration of the VFS code into the kernel. vsock - Host Linux kernel with vhost-vsock support, introduced in Linux 4. This is a Linux kernel device driver module that provides datagram and stream socket interfaces to the underlying VMCI device. Share folder from Windows OS to Oracle linux 6 OS. diff --git a/tools/testing/selftests/ftrace/test. VSOCK is useful for lightweight VMs since TCP/IP stack and network interfaces are not involved. Home; Engineering; Training; Docs. A malicious virtual guest under specific conditions can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. With VMware Server you can create and run guest operating systems ("virtual machines") such as Linux, Windows, FreeBSD, etc. I have extracted kernel source from downloaded rpm and inside it, I have untared the actual.
