[libvirt] [PATCHv3 0/2] pci: properly handle out-of-order SRIOV virtual functions
by Laine Stump
This resolves:
https://bugzilla.redhat.com/show_bug.cgi?id=1025397
It has turned from a single patch into a 2 part patch because I wanted
to use VIR_APPEND_ELEMENT on the array, and that requires the array
size to be held in a size_t rather than unsigned int.
Thanks to Martin's suggestion (and similar suggestions from both Jan
and "Niilona" (the original reporter of the problem), this version is
greatly simplified from either my previous version or even the
original code (as evidenced by the diffstat).

[libvirt] [PATCHv2] pci: properly handle out-of-order SRIOV virtual functions
by Laine Stump
This resolves:
https://bugzilla.redhat.com/show_bug.cgi?id=1025397
When libvirt creates the list of an SRIOV Physical Function's (PF)
Virtual Functions (VF), it assumes that the order of "virtfn*" links
returned by readdir() from the PF's sysfs directory is already in the
correct order. Experience has shown that this is not always the case.
This results in 1) incorrect assumptions made by consumers of the
output of the virt_functions list of virsh nodedev-dumpxml, and 2)
setting MAC address and vlan tag on the wrong VF (since libvirt uses
netlink to set mac address and vlan tag, netlink requires the VF#, and
the function virPCIGetVirtualFunctionIndex() returns the wrong index
due to the improperly ordered VF list). See the bugzilla report for an
example of this improper behavior.
The solution provided by this patch is for virPCIGetVirtualFunctions
to first gather all the "virtfn*" names from the PFs sysfs directory,
then allocate a virtual_functions array large enough to hold all
entries, and finally to create a device entry for each virtfn* name
and place it into the virtual_functions array at the proper index
(based on interpreting the value following "virtfn" in the name).
Checks are introduced to ensure that 1) the virtfn list given in sysfs
is not sparse (ie, there are no indexes larger than the length of the
list), and that no two virtfn* entries decode to the same index.
---
Difference from V1: Based on jtomko's review, truncate trailing NULLs
in virtual_functions array, and actually check for NULLs in the middle
(a sparse array) and generate an error in that case, as we already
claimed to do in the commit message.
(Sorry for the lack of inter-diff, but the only changes from V1 are
the addition of the lines starting with "truncate any trailing nulls"
and continuing until the next VIR_DEBUG.)

[libvirt] [PATCH 1/1] storage: Fix a vol-clone bug for ppc64
by Li Zhang
From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com>
vol-clone reports out of memory error with disk type on ppc64.
Currently, wbytes is defined as size_t type which is 8 bytes on ppc64,
but args's value in ioctl(fd, args..) in kernel is unsigned int.
So it will read more 4 bytes by ioctl() with size_t from memory which
gets a large number and causes out of memory error.
This patch changes size_t to unsigned int to synchronize with kernel.
