This function returns T if the given name is a macvtap device. This is determined by 1) getting the ifindex of the device with that name (if there is one), and 2) checking for existence of /dev/tapXX, where "XX" is the ifindex learned in (1). It's also possible to learn this by getting a netlink dump of the interface and parsing through it to look for some attributes, but that is complicated to figure out, takes longer to execute, and I'm lazy.

There are already good number of test cases with hostdevices, few have multifunction devices but none having more than one than one multifunction cards. This patch adds a case where there are two multifunction cards and two Virtual functions part of the same XML. 0001:01:00.X & 0005:09:00.X - are Multifunction PCI cards. 0000:06:12.[5|6] - are SRIOV Virtual functions Future commits will improve on automatically detecting the multifunction cards and auto-assinging the addresses appropriately.

Previous patch had to add '/sys/kernel/' prefix in opendir() because the path, which is being mocked, wasn't being considered due to an 'if SYSFS_PCI_PREFIX' guarding the call to getrealpath(). In fact, all current getrealpath() callers are guarding it with a conditional to ensure that the function will never be called with a non-mocked path. In this case, an extra non-NULL verification is needed for the 'newpath' string to use the variable - which is counterintuitive, given that getrealpath() will always write the 'newpath' string in any non-error conditon. However, simply removing the guard of all getrealpath() instances causes an abort in init_env(). This happens because tests will execute access() to non-mocked paths even before the LIBVIRT_FAKE_ROOT_DIR variable is declared in the test files. We don't need 'fakerootdir' to be created at this point though. This patch does the following changes to simplify getrealpath() usage: - getrealpath() will now guard the init_env() call by checking if both fakeroot isn't created and the required path is being mocked. This ensures that we're not failing inside init_env() because we're too early and LIBVIRT_FAKE_ROOT_DIR wasn't defined yet; - remove all conditional guards to call getrealpath() from access(), virMockStatRedirect(), open(), open_2(), opendir() and virFileCanonicalizePath(). As a bonus, remove all ternary conditionals with 'newpath'; - a new 'pathPrefixIsMocked()' helper to aggregate all the prefixes we're mocking, making it easier to add/remove them. If a prefix is added inside this function, we can be sure that all functions are mocking them.

This patch adds hostdev test cases in qemuhotplugtest.c. Note: the small tweak inside virpcimock.c was needed because the new tests added a code path in which virHostHasIOMMU() (virutil.c) started being called, and the mocked '/sys/kernel/' prefix that is mocked in virpcimock.c wasn't being considered in the opendir() mock. An alternative to avoid these situations in virpcimock.c is implemented in the next patch.

The softlink to physfn is the way to know if the device is VF or not. So, the patch softlinks 'physfn' to the parent function. The multifunction PCI devices dont have 'physfn' softlinks. The patch adds few Virtual functions to the mock environment and changes the existing VFIO test xmls using the VFs to use the newly added VFs for their use case.

When starting a domain, we use the presence of a vfio-pci or mdev hostdev to determine if the memlock maximum needs to be increased. But if we hotplug either of these devices, only the vfio-pci path gets that love. This means that attaching a, say, vfio-ccw device will appear to succeed but the device may be unusable as the guest may see I/O errors on long CCW chains. The host, meanwhile, would be flooded with these messages: vfio_pin_page_external: Task qemu-system-s39 (11584) RLIMIT_MEMLOCK (65536) exceeded Let's adjust the maximum memlock value in the mdev hotplug path, so that the domain has the same value as if it were started with one or more mdev devices in its configuration.

If attaching a PCI hostdev fails, there are several things that need to be un-done as part of the cleanup. One thing that is not done is re-calculating/re-setting the maximum amount of locked memory for the domain, since we may have changed that.

We currently generate two completely separate API references for the libvirt public API. One at 'docs/html/' and one at 'docs/devhelp/'. Both are published on the website, but we only link to content in the 'docs/html/' pages. Both are installed in the libvirt-docs sub-RPM, with a full copy of the website including 'docs/html/' in /usr/share/docs/libvirt-docs, while the 'docs/devhelp/' content goes to /usr/share/gtk-doc/. The latter was broken for years until: commit ca6f6025 Author: Andrea Bolognani <abologna@redhat.com> Date: Fri May 10 14:54:52 2019 +0200 docs: Introduce $(devhelphtml_generated) Our XSLT magic generates one Devhelp-compatible HTML file per documentation module, but so far we have only shipped and installed documentation for virterror. Now that we have $(modules), however, we can generate the list of files the same way we do for regular documentation and make sure we always ship and install everything. That this bug went unnoticed for so long is a sign of how few people are using the devhelp docs. The only commits to the devhelp code since it was first introduced have been fixing various build problems that hit. The only obvious difference between the two sets of docs is the CSS styling in use. Overall devhelp does not look compelling enough to justify having two duplicated sets of API docs. Eliminating it will reduce the amount of XSL code we are carrying in the tree which is an attractive benefit.

This is an issue for LXC loop devices when you are trying to get loop devices info using `ioctl`. Modern apps uses `/sys/dev/block` to grab information about devices, but if you use the method mention you won't be able to retrive the associated file with that loop device. See example below from cryptsetup sources: static char *_ioctl_backing_file(const char *loop) { struct loop_info64 lo64 = {0}; int loop_fd; loop_fd = open(loop, O_RDONLY); if (loop_fd < 0) return NULL; if (ioctl(loop_fd, LOOP_GET_STATUS64, &lo64) < 0) { close(loop_fd); return NULL; } lo64.lo_file_name[LO_NAME_SIZE-2] = '*'; lo64.lo_file_name[LO_NAME_SIZE-1] = 0; close(loop_fd); return strdup((char*)lo64.lo_file_name); } It will return an empty string because lo_file_name was not set. Function `virFileLoopDeviceOpenSearch()` is using `ioctl` to query data, but it is not checking `lo_file_name` field. Reviewed-by: NDaniel P.
