2020-06-03riscv: Change the default behavior if no -bios option is specifiedBin Meng
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.

If multiple packets miscompare in a short timeframe, the semaphore value will be increased multiple times. This causes multiple checkpoints even if one would be sufficient.

2020-06-01virtiofsd: remove symlink fallbacksMiklos Szeredi
Path lookup in the kernel has special rules for looking up magic symlinks under /proc. 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.
