2020-10-26tests/acceptance: Add virtiofs_submounts.pyMax Reitz5-0/+630
This test invokes several shell scripts to create a random directory tree full of submounts, and then check in the VM whether every submount has its own ID and the structure looks as expected. (Note that the test scripts must be non-executable, so Avocado will not try to execute them as if they were tests on their own, too.) Because at this commit's date it is unlikely that the Linux kernel on the image provided by boot_linux.py supports submounts in virtio-fs, the test will be cancelled if no custom Linux binary is provided through the vmlinuz parameter. (The on-image kernel can be used by providing an empty string via vmlinuz=.) So, invoking the test can be done as follows: $ avocado run \ tests/acceptance/virtiofs_submounts.py \ -p vmlinuz=/path/to/linux/build/arch/x86/boot/bzImage This test requires root privileges (through passwordless sudo -n), because at this point, virtiofsd requires them. (If you have a timestamp_timeout period for sudoers (e.g. the default of 5 min), you can provide this by executing something like "sudo true" before invoking Avocado.)

2020-10-26virtiofsd: Announce sub-mount pointsMax Reitz2-8/+60
Whenever we encounter a directory with an st_dev that differs from that of its parent, we set the FUSE_ATTR_SUBMOUNT flag so the guest can create a submount for it. Make this behavior optional, so submounts are only announced to the guest with the announce_submounts option. Some users may prefer the current behavior, so that the guest learns nothing about the host mount structure.

2020-10-26virtiofsd: Store every lo_inode's parent_devMax Reitz1-0/+17
We want to detect mount points in the shared tree. We report them to the guest by setting the FUSE_ATTR_SUBMOUNT flag in fuse_attr.flags, but because the FUSE client will create a submount for every directory that has this flag set, we must do this only for the actual mount points. We can detect mount points by comparing a directory's st_dev with its parent's st_dev. To be able to do so, we need to store the parent's st_dev in the lo_inode object. Note that mount points need not necessarily be directories; a single file can be a mount point as well. However, for the sake of simplicity let us ignore any non-directory mount points for now.

Add an option to define mappings of xattr names so that the client and server filesystems see different views. This can be used to have different SELinux mappings as seen by the guest, to run the virtiofsd with less privileges (e.g. in a case where it can't set trusted/system/security xattrs but you want the guest to be able to), or to isolate multiple users of the same name; e.g. trusted attributes used by stacking overlayfs. A mapping engine is used with 3 simple rules; the rules can be combined to allow most useful mapping scenarios. The ruleset is defined by -o xattrmap='rules...'. This patch doesn't use the rule maps yet.

2020-10-26virtiofsd: add container-friendly -o sandbox=chroot optionStefan Hajnoczi3-9/+88
virtiofsd cannot run in a container because CAP_SYS_ADMIN is required to create namespaces. Introduce a weaker sandbox mode that is sufficient in container environments because the container runtime already sets up namespaces. Use chroot to restrict path traversal to the shared directory. virtiofsd loses the following: 1. Mount namespace. The process chroots to the shared directory but leaves the mounts in place. Seccomp rejects mount(2)/umount(2) syscalls. 2. Pid namespace. This should be fine because virtiofsd is the only process running in the container. 3. Network namespace. This should be fine because seccomp already rejects the connect(2) syscall, but an additional layer of security is lost. Container runtime-specific network security policies can be used drop network traffic (except for the vhost-user UNIX domain socket).

Currently it is unknown whether virtiofsd will be built at configuration time. It will be automatically built when dependency is met. Also, required libraries are not clear.

2020-10-26trace/simple: Enable tracing on startup only if the user specifies a trace ↵Josh DuBois1-1/+5
option Tracing can be enabled at the command line or via the monitor. Command-line trace options are recorded during trace_opt_parse(), but tracing is not enabled until the various front-ends later call trace_init_file(). If the user passes a trace option on the command-line, remember that and enable tracing during trace_init_file(). Otherwise, trace_init_file() should record the trace file specified by the frontend and avoid enabling traces until the user requests them via the monitor. This fixes 1b7157be3a8c4300fc8044d40f4b2e64a152a1b4 and also db25d56c014aa1a96319c663e0a60346a223b31e, by allowing the user to enable traces on the command line and also avoiding unwanted trace-<pid> files when the user has not asked for them.

2020-10-26migration-test: Only hide error if !QTEST_LOGPeter Xu1-1/+5
The errors are very useful when debugging qtest failures, especially when QTEST_LOG=1 is set. Let's allow override MigrateStart.hide_stderr when QTEST_LOG=1 is specified, because that means the user wants to be verbose. Not very nice to introduce the first QTEST_LOG env access in migration-test.c, however it should be handy. Without this patch, I was hacking error_report() when debugging such errors. Let's make things easier.

2020-10-26migration/postcopy: Release fd before going into 'postcopy-pause'Peter Xu1-3/+3
Logically below race could trigger with the old code: test program migration thread ------------ ---------------- wait_until('postcopy-pause') postcopy_pause() set_state('postcopy-pause') do_postcopy_recover() arm s->to_dst_file with new fd release s->to_dst_file [1] Here [1] could have released the just-installed recoverying channel. Then the migration could hang without really resuming. Instead, it should be very safe to release the fd before setting the state into 'postcopy-pause', because there's no reason for any other thread to touch it during 'postcopy-active'. Dave reported a very rare postcopy recovery hang that the migration-test program waited for the migration to complete in migrate_postcopy_complete(). We do suspect it's the same thing that we're gonna fix here. Hard to tell. However since we've noticed this, fix this irrelevant of the hang report.

2020-10-26migration: Maintain postcopy faulted addressesPeter Xu4-5/+74
Maintain a list of faulted addresses on the destination host for which we're waiting on. This is implemented using a GTree rather than a real list to make sure even there're plenty of vCPUs/threads that are faulting, the lookup will still be fast with O(log(N)) (because we'll do that after placing each page). It should bring a slight overhead, but ideally that shouldn't be a big problem simply because in most cases the requested page list will be short. Actually we did similar things for postcopy blocktime measurements. This patch didn't use that simply because: (1) blocktime measurement is towards vcpu threads only, but here we need to record all faulted addresses, including main thread and external thread (like, DPDK via vhost-user). (2) blocktime measurement will require UFFD_FEATURE_THREAD_ID, but here we don't want to add that extra dependency on the kernel version since not necessary. E.g., we don't need to know which thread faulted on which page, we also don't care about multiple threads faulting on the same page. But we only care about what addresses are faulted so waiting for a page copying from src. (3) blocktime measurement is not enabled by default. However we need this by default especially for postcopy recover. Another thing to mention is that this patch introduced a new mutex to serialize the receivedmap and the page_requested tree, however that serialization does not cover other procedures like UFFDIO_COPY.
