`struct dirent' returned from readdir(3) could be shorter (or longer)
than `sizeof(struct dirent)', thus memcpy of sizeof length will overread
into unallocated page causing SIGSEGV. Example stack trace:

The 9p test cases use mkdtemp() to create a temporary directory for
running the 'local' 9p tests with real files/dirs. Unlike mktemp()
which only generates a unique file name, mkdtemp() also creates the
directory, therefore the subsequent mkdir() was wrong and caused
errors on some systems.

It is recommended to use g_autofree or g_autoptr as it reduces

Previously, HV_CPUID_NESTED_FEATURES.EAX CPUID leaf was handled differently

This patchset tries to address the issue raised in

Patch 2 and patch 3 are dependent on patch 1.

This is a minor cleanup. Using macro definitions makes the code more

When the host supports the CPU topology facility, the PTF
instruction with function code 2 is interpreted by the SIE,
provided that the userland hypervizor activates the interpretation
by using the KVM_CAP_S390_CPU_TOPOLOGY KVM extension.
The PTF instructions with function code 0 and 1 are

With the current implementation, blocking flock can lead to

Add capability to enable and parse security context as sent by client
and put into fuse_req. Filesystems now can get security context from

Right now these fields are 32bit in size. But now fuse has run out of

Move core file creation bits in a separate function. Soon this is going
to get more complex as file creation need to set security context also.
And there will be multiple modes of file creation in next patch.

Add some code to parse extended "struct fuse_init_in". And use a local
variable "flag" to represent 64 bit flags. This will make it easier
to add more features without having to worry about two 32bit flags (->flags
and ->flags2) in "fuse_struct_in".

Unfortunately, this patch breaks migration under TCG because the XIVE
source flag is not updated on the target side. KVM is not impacted
because the emulated sources are not used. This needs to be addressed
in a v2.
That said, even without this patch, TCG migration is broken. some CPUs

This patch implements initial support for Single Root I/O Virtualization
on an NVMe device.
Essentially, it allows to define the maximum number of virtual functions
supported by the NVMe controller via sriov_max_vfs parameter.
