* riscv: Change the default behavior if no -bios option is specifiedBin Meng2020-06-031-27/+4Star
| | | | | | | | | | | | | | | | | | | Per QEMU deprecated doc, QEMU 4.1 introduced support for the -bios option in QEMU for RISC-V for the virt machine and sifive_u machine. The default behavior has been that QEMU does not automatically load any firmware if no -bios option is included. Now 2 releases passed, it's time to change the default behavior to load the default OpenSBI firmware automatically. The firmware is included with the QEMU release and no user interaction is required. All a user needs to do is specify the kernel they want to boot with the -kernel option.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 5.0 QEMU uses hostmem backend for allocating main guest RAM. The backend however calls mbind() which is typically NOP in case of default policy/absent host-nodes bitmap. However when runing in container with black-listed mbind() syscall, QEMU fails to start with error "cannot bind memory to host NUMA nodes: Operation not permitted" even when user hasn't provided host-nodes to pin to explictly (which is the case with -m option) To fix issue, call mbind() only in case when user has provided host-nodes explicitly (i.e. host_nodes bitmap is not empty). That should allow to run QEMU in containers with black-listed mbind() without memory pinning. If QEMU provided memory-pinning is required user still has to white-list mbind() in container configuration.

However if we failover during checkpoint, CPUState is not initialized and the registers are loaded with garbage. This causes guest hangs and crashes. Fix this by using cpu_synchronize_all_states(), which initializes CPUState from the current cpu registers additionally to marking the vcpus as dirty.

| * | migration/colo.c: Use event instead of semaphoreLukas Straub2020-06-012-6/+7

This causes multiple checkpoints even if one would be sufficient. Fix this by using a event instead of a semaphore for triggering checkpoints. Now, checkpoint requests will be ignored until the checkpoint event is sent to colo-compare (which releases the miscompared packets).

| * | virtiofsd: remove symlink fallbacksMiklos Szeredi2020-06-011-169/+6Star

If a filesystem operation is instructed to follow symlinks (e.g. via AT_SYMLINK_FOLLOW or lack of AT_SYMLINK_NOFOLLOW), and the final component is such a proc symlink, then the target of the magic symlink is used for the operation, even if the target itself is a symlink. I.e. path lookup is always terminated after following a final magic symlink. I was erronously assuming that in the above case the target symlink would also be followed, and so workarounds were added for a couple of operations to handle the symlink case. Since the symlink can be handled simply by following the proc symlink, these workardouds are not needed. Also remove the "norace" option, which disabled the workarounds. Commit bdfd66788349 ("virtiofsd: Fix xattr operations") already dealt with the same issue for xattr operations.
