2020-12-03selftests: kvm/set_memory_region_test: Fix race in move region testMaciej S. Szmigiero
The current memory region move test correctly handles the situation that the second (realigning) memslot move operation would temporarily trigger MMIO until it completes, however it does not handle the case in which the first (misaligning) move operation does this, too. This results in false test assertions in case it does so. Fix this by handling temporary MMIO from the first memslot move operation in the test guest code, too.

2020-12-03macvlan: Support for high multicast packet rateThomas Karlsson
Background: Broadcast and multicast packages are enqueued for later processing. This queue was previously hardcoded to 1000. This proved insufficient for handling very high packet rates. This resulted in packet drops for multicast. While at the same time unicast worked fine. The change: This patch make the queue length adjustable to accommodate for environments with very high multicast packet rate. But still keeps the default value of 1000 unless specified. The queue length is specified as a request per macvlan using the IFLA_MACVLAN_BC_QUEUE_LEN parameter. The actual used queue length will then be the maximum of any macvlan connected to the same port. The actual used queue length for the port can be retrieved (read only) by the IFLA_MACVLAN_BC_QUEUE_LEN_USED parameter for verification. This will be followed up by a patch to iproute2 in order to adjust the parameter from userspace.

2020-12-02selftests: Add benchmark for syscall user dispatchGabriel Krisman Bertazi
This is the patch I'm using to evaluate the impact syscall user dispatch has on native syscall (syscalls not redirected to userspace) when enabled for the process and submiting syscalls though the unblocked dispatch selector. It works by running a step to define a baseline of the cost of executing sysinfo, then enabling SUD, and rerunning that step. On my test machine, an AMD Ryzen 5 1500X, I have the following results with the latest version of syscall user dispatch patches. root@olga:~# syscall_user_dispatch/sud_benchmark Calibrating test set to last ~5 seconds... test iterations = 37500000 Avg syscall time 134ns.

Since the setup script required by test_ima (ima_setup.sh) is not mentioned in the dependencies, it does not get copied to these subdirectories and causes flavored variants of test_ima to fail.

2020-11-30ktest.pl: Fix incorrect reboot for grub2blsLibo Chen
This issue was first noticed when I was testing different kernels on Oracle Linux 8 which as Fedora 30+ adopts BLS as default. Even though a kernel entry was added successfully and the index of that kernel entry was retrieved correctly, ktest still wouldn't reboot the system into user-specified kernel. The bug was spotted in subroutine reboot_to where the if-statement never checks for REBOOT_TYPE "grub2bls", therefore the desired entry will not be set for the next boot. Add a check for "grub2bls" so that $grub_reboot $grub_number can be run before a reboot if REBOOT_TYPE is "grub2bls" then we can boot to the correct kernel.
