2020-10-26tools/virtiofsd: xattr name mappings: Simple 'map'Dr. David Alan Gilbert1-0/+19
The mapping rule system implemented in the last few patches is extremely flexible, but not easy to use. Add a simple 'map' type as a sprinkling of sugar to make it easy. e.g. -o xattrmap=":map::user.virtiofs.:" would be sufficient to prefix all xattr's or -o xattrmap=":map:trusted.:user.virtiofs.:" would just prefix 'trusted.' xattr's and leave everything else alone.

2020-10-26tools/virtiofsd: xattr name mappings: Add optionDr. David Alan Gilbert1-0/+92
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 Hajnoczi1-7/+25
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).

2020-10-17build: replace ninjatool with ninjaPaolo Bonzini1-4/+2
Now that the build is done entirely by Meson, there is no need to keep the Makefile conversion. Instead, we can ask Ninja about the targets it exposes and forward them. The main advantages are, from smallest to largest: - reducing the possible namespace pollution within the Makefile - removal of a relatively large Python program - faster build because parsing Makefile.ninja is slower than parsing build.ninja; and faster build after Meson runs because we do not have to generate Makefile.ninja. - tracking of command lines, which provides more accurate rebuilds In addition the change removes the requirement for GNU make 3.82, which was annoying on Mac, and avoids bugs on Windows due to ninjatool not knowing how to convert Windows escapes to POSIX escapes.

2020-10-15block: deprecate the sheepdog block driverDaniel P. Berrangé1-0/+9
This thread from a little over a year ago: http://lists.wpkg.org/pipermail/sheepdog/2019-March/thread.html states that sheepdog is no longer actively developed. The only mentioned users are some companies who are said to have it for legacy reasons with plans to replace it by Ceph. There is talk about cutting out existing features to turn it into a simple demo of how to write a distributed block service. There is no evidence of anyone working on that idea: https://github.com/sheepdog/sheepdog/commits/master No real commits to git since Jan 2018, and before then just some minor technical debt cleanup. There is essentially no activity on the mailing list aside from patches to QEMU that get CC'd due to our MAINTAINERS entry. Fedora packages for sheepdog failed to build from upstream source because of the more strict linker that no longer merges duplicate global symbols. Fedora patches it to add the missing "extern" annotations and presumably other distros do to, but upstream source remains broken. There is only basic compile testing, no functional testing of the driver. Since there are no build pre-requisites the sheepdog driver is currently enabled unconditionally. This would result in configure issuing a deprecation warning by default for all users. Thus the configure default is changed to disable it, requiring users to pass --enable-sheepdog to build the driver.

2020-10-13docs/system/deprecated: Mark the 'moxie' CPU as deprecatedThomas Huth1-0/+8
It is currently unclear whether anybody is still using the 'moxie' CPU, and there are no images for testing available this CPU, so the code has likely bit-rotten in the course of time. When I asked the maintainer for information, I did not get a reply within four weeks yet (see https://lists.gnu.org/archive/html/qemu-devel/2020-08/msg07201.html). The last Signed-off-by line from Anthony in our repo is from 2013, so it seems like this code is rather unmaintained. Time to put it onto the deprecation list to see whether somebody is still interested in this code or whether we could remove it in a couple of releases.

2020-10-09hmp: Add support for coroutine command handlersKevin Wolf1-2/+2
Often, QMP command handlers are not only called to handle QMP commands, but also from a corresponding HMP command handler. In order to give them a consistent environment, optionally run HMP command handlers in a coroutine, too. The implementation is a lot simpler than in QMP because for HMP, we still block the VM while the coroutine is running.

2020-10-09qapi: Add a 'coroutine' flag for commandsKevin Wolf2-1/+30
This patch adds a new 'coroutine' flag to QMP command definitions that tells the QMP dispatcher that the command handler is safe to be run in a coroutine. The documentation of the new flag pretends that this flag is already used as intended, which it isn't yet after this patch. We'll implement this in another patch in this series.

2020-10-05scripts: add block-coroutine-wrapper.pyVladimir Sementsov-Ogievskiy2-0/+55
We have a very frequent pattern of creating a coroutine from a function with several arguments: - create a structure to pack parameters - create _entry function to call original function taking parameters from struct - do different magic to handle completion: set ret to NOT_DONE or EINPROGRESS or use separate bool field - fill the struct and create coroutine from _entry function with this struct as a parameter - do coroutine enter and BDRV_POLL_WHILE loop Let's reduce code duplication by generating coroutine wrappers. This patch adds scripts/block-coroutine-wrapper.py together with some friends, which will generate functions with declared prototypes marked by the 'generated_co_wrapper' specifier. The usage of new code generation is as follows: 1. define the coroutine function somewhere int coroutine_fn bdrv_co_NAME(...) {...} 2. declare in some header file int generated_co_wrapper bdrv_NAME(...); with same list of parameters (generated_co_wrapper is defined in "include/block/block.h"). 3. Make sure the block_gen_c declaration in block/meson.build mentions the file with your marker function. Still, no function is now marked, this work is for the following commit.
