In the non linux case some callers like gather_scsi_host_caps needed the
return code of -1 while others like update_caps needed an empty
statement (to avoid a "statement without effect" warning). This is much
simpler solved by using a function instead of a define.
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.
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>
* docs/formatnode.html.in: (Document the new XML)
* docs/schemas/nodedev.rng: (Add the schema)
* src/conf/node_device_conf.h: (New member for data.scsi_host)
* src/node_device/node_device_linux_sysfs.c: (Collect the value of
max_vports and vports)
This adds two util functions (virIsCapableFCHost and virIsCapableVport),
and rename helper check_fc_host_linux as detect_scsi_host_caps,
check_capable_vport_linux is removed, as it's abstracted to the util
function virIsCapableVport. detect_scsi_host_caps nows detect both
the fc_host and vport_ops capabilities. "stat(2)" is replaced with
"access(2)" for saving.
* src/util/virutil.h:
- Declare virIsCapableFCHost and virIsCapableVport
* src/util/virutil.c:
- Implement virIsCapableFCHost and virIsCapableVport
* src/node_device/node_device_linux_sysfs.c:
- Remove check_capable_vport_linux
- Rename check_fc_host_linux as detect_scsi_host_caps, and refactor
it a bit to detect both fc_host and vport_os capabilities
* src/node_device/node_device_driver.h:
- Change/remove the related declarations
* src/node_device/node_device_udev.c: (Use detect_scsi_host_caps)
* src/node_device/node_device_hal.c: (Likewise)
* src/node_device/node_device_driver.c (Likewise)
"open_wwn_file" in node_device_linux_sysfs.c is redundant, on one
hand it duplicates work of virFileReadAll, on the other hand, it's
waste to use a function for it, as there is no other users of it.
So I don't see why the file opening work cannot be done in
"read_wwn_linux".
"read_wwn_linux" can be abstracted as an util function. As what all
it does is to read the sysfs entry.
So this patch removes "open_wwn_file", and abstract "read_wwn_linux"
as an util function "virReadFCHost" (a more general name, because
after changes, it can read each of the fc_host entry now).
* src/util/virutil.h: (Declare virReadFCHost)
* src/util/virutil.c: (Implement virReadFCHost)
* src/node_device/node_device_linux_sysfs.c: (Remove open_wwn_file,
and read_wwn_linux)
src/node_device/node_device_driver.h: (Remove the declaration of
read_wwn_linux, and the related macros)
src/libvirt_private.syms: (Export virReadFCHost)

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)
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.

These VIR_XXXX0 APIs make us confused, use the non-0-suffix APIs instead.
How do these coversions works? The magic is using the gcc extension of ##.
When __VA_ARGS__ is empty, "##" will swallow the "," in "fmt," to
avoid compile error.
example: origin after CPP
high_level_api("%d", a_int) low_level_api("%d", a_int)
high_level_api("a string") low_level_api("a string")
About 400 conversions.
8 special conversions:
VIR_XXXX0("") -> VIR_XXXX("msg") (avoid empty format) 2 conversions
VIR_XXXX0(string_literal_with_%) -> VIR_XXXX(%->%%) 0 conversions
VIR_XXXX0(non_string_literal) -> VIR_XXXX("%s", non_string_literal)
(for security) 6 conversions

Using automated replacement with sed and editing I have now replaced all
occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of
course. Some replacements were straight forward, others I needed to pay
attention. I hope I payed attention in all the right places... Please
have a look. This should have at least solved one more double-close
error.
Some kernels, such as the one used in RHEL-5, have vport_create and
vport_delete operation files in /sys/class/scsi_host/hostN directory
instead of /sys/class/fc_host/hostN. Let's check both paths for
compatibility reasons.
This also removes unnecessary '/' characters from sysfs paths containing
LINUX_SYSFS_FC_HOST_PREFIX.
it causes a NULL-dereference on some systems like Solaris 10.
* src/node_device/node_device_linux_sysfs.c. Include <stdlib.h>.
(get_sriov_function): Use canonicalize_file_name, not realpath.
* bootstrap (modules): Add canonicalize-lgpl.
Two files were using functions from <sys/stat.h> but not including
in. Most of the time they got this automatically via another header,
but certain build flag combinations can reveal the problem
* src/lxc/lxc_container.c, src/node_device/node_device_linux_sysfs.c:
Add <sys/stat.h>
I noticed some debug messages are printed with an empty lines after

VIR_DEBUG0
VIR_ERROR
VIR_ERROR0
VIR_INFO
VIR_WARN
VIR_WARN0
