Since scsi generic device doesn't have DEVTYPE property set, the
only way to know if it's a scsi generic device or not is to read
the "SUBSYSTEM" property.
The XML of the scsi generic device will be like:
<device>
<name>scsi_generic_sg0</name>
<path>/sys/devices/pci0000:00/0000:00:1f.2/ata1/host0/target0:0:0/0:0:0:0/scsi_generic/sg0</path>
<parent>scsi_0_0_0_0</parent>
<capability type='scsi_generic'>
<char>/dev/sg0</char>
</capability>
</device>
The name format is constructed by libvirt, it's not that clear to
get what the device's sysfs path should be. This exposes the device's
sysfs path by a new tag <path>.
Since the sysfspath is filled during enumerating the devices by
either udev or HAL. It's an output-only tag.
The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
Detected by a simple Shell script:
for i in $(git ls-files -- '*.[ch]'); do
awk 'BEGIN {
fail=0
}
/# *include.*\.h/{
match($0, /["<][^">]*[">]/)
arr[substr($0, RSTART+1, RLENGTH-2)]++
}
END {
for (key in arr) {
if (arr[key] > 1) {
fail=1
printf("%d %s\n", arr[key], key)
}
}
if (fail == 1)
exit 1
}' $i
if test $? != 0; then
echo "Duplicate header(s) in $i"
fi
done;
A later patch will add the syntax-check to avoid duplicate
headers.
This enrichs HBA's xml by dumping the number of max vports and
vports in use. Format is like:
<capability type='vport_ops'>
<max_vports>164</max_vports>
<vports>5</vports>
</capability>

VIR_CONNECT_LIST_NODE_DEVICES_CAP_FC_HOST to filter the FC HBA,
and VIR_CONNECT_LIST_NODE_DEVICES_CAP_VPORTS to filter the FC HBA
which supports vport.
Guess it was created for the fc_host and vports_ops capabilities
purpose, but there is enum virNodeDevScsiHostCapFlags for them,
and enum virNodeDevHBACapType is unused, and actually both
VIR_ENUM_DECL and VIR_ENUM_IMPL use the wrong enum name
"virNodeDevHBACap".

<quote>
the first nibble is either hex 5 or 6 followed by a 3-byte vendor
identifier and 36 bits for a vendor-specified serial number.
</quote>
We choose hex 5 for the first nibble. And for the 3-bytes vendor ID,
we uses the OUI according to underlying hypervisor type, (invoking
virConnectGetType to get the virt type). e.g. If virConnectGetType
returns "QEMU", we use Qumranet's OUI (00:1A:4A), if returns
ESX|VMWARE, we use VMWARE's OUI (00:05:69). Currently it only
supports qemu|xen|libxl|xenapi|hyperv|esx|vmware drivers. The last
36 bits are auto-generated.
This patch is to expose the fabric_name of fc_host class, which
might be useful for users who wants to known which fabric the
(v)HBA connects to.
The patch also adds the missed capabilities' XML schema of scsi_host,
(of course, with fabric_wwn added), and update the documents
(docs/formatnode.html.in)
Commit 498d783 cleans up some of virtual file names for parsing strings
in memory. This patch cleans up (hopefuly) the rest forgotten by the
first patch.
This patch also changes all of the previously modified "filenames" to
valid URI's replacing spaces for underscores.
Changes to v1:
- Replace all spaces for underscores, so that the strings form valid
URI's
- Replace spaces in places changed by commit 498d783
This patch moves some of the sriov related pci code from node_device driver
to src/util/pci.[ch]. Some functions had to go thru name and argument list
change to accommodate the move.

We already have virAsprintf, so picking a similar name helps for
seeing a similar purpose. Furthermore, the prefix V before printf
generally implies 'va_list', even though this variant was '...', and
the old name got in the way of adding a new va_list version.
global rename performed with:
$ git grep -l virBufferVSprintf \
| xargs -L1 sed -i 's/virBufferVSprintf/virBufferAsprintf/g'
then revert the changes in ChangeLog-old.
The virConnectPtr is no longer required for error reporting since
that is recorded in a thread local. Remove use of virConnectPtr
from all APIs in node_device_conf.{h,c} and update all callers to
match
Replace free(virBufferContentAndReset()) with virBufferFreeAndReset().
Update documentation and replace all remaining calls to free() with
calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset()
and virReportOOMError() in OOM error cases.
Erroneously included the sysfs_path and parent_sysfs_path elements in
the node device xml, they were not supposed to show up there
* src/conf/node_device_conf.c: remove the output of the 2 fields
I realized that I inadvertently added a member to the def struct to
contain each device's sysfs path when there was an existing member in the
dev struct for "OS specific path to device metadat, eg sysfs" Since the
udev backend needs to record the sysfs path while it's in the process of
creating the device, before the dev struct gets allocated, I chose to
remove the member from the dev struct.

If no matching device was found (cap == NULL) then no strdup() call
was made and *wwnn and *wwpn are untouched. Checking them for NULL
in this situation may result in reporting an false-positive OOM error
because *wwnn and *wwpn may be initialized to NULL by the caller.
Only check *wwnn and *wwpn for NULL if a matching device was found
(cap != NULL) and thus strdup() was called.
* src/conf/node_device_conf.c: only report an OOM error if there
really is one
Add virNodeDeviceParseFile, and make virNodeDeviceParseNode non-static. These
will be used by the test driver.
