tests: simplify common setup A few of the tests were missing basic sanity checks, while most of them were doing copy-and-paste initialization (in fact, some of them pasted the argc > 1 check more than once!). It's much nicer to do things in one common place, and minimizes the size of the next patch that fixes getcwd usage. * tests/testutils.h (EXIT_AM_HARDFAIL): New define. (progname, abs_srcdir): Define for all tests. (VIRT_TEST_MAIN): Change callback signature. * tests/testutils.c (virtTestMain): Do more common init. * tests/commandtest.c (mymain): Simplify. * tests/cputest.c (mymain): Likewise. * tests/esxutilstest.c (mymain): Likewise. * tests/eventtest.c (mymain): Likewise. * tests/hashtest.c (mymain): Likewise. * tests/networkxml2xmltest.c (mymain): Likewise. * tests/nodedevxml2xmltest.c (myname): Likewise. * tests/nodeinfotest.c (mymain): Likewise. * tests/nwfilterxml2xmltest.c (mymain): Likewise. * tests/qemuargv2xmltest.c (mymain): Likewise. * tests/qemuhelptest.c (mymain): Likewise. * tests/qemuxml2argvtest.c (mymain): Likewise. * tests/qemuxml2xmltest.c (mymain): Likewise. * tests/qparamtest.c (mymain): Likewise. * tests/sexpr2xmltest.c (mymain): Likewise. * tests/sockettest.c (mymain): Likewise. * tests/statstest.c (mymain): Likewise. * tests/storagepoolxml2xmltest.c (mymain): Likewise. * tests/storagevolxml2xmltest.c (mymain): Likewise. * tests/virbuftest.c (mymain): Likewise. * tests/virshtest.c (mymain): Likewise. * tests/vmx2xmltest.c (mymain): Likewise. * tests/xencapstest.c (mymain): Likewise. * tests/xmconfigtest.c (mymain): Likewise. * tests/xml2sexprtest.c (mymain): Likewise. * tests/xml2vmxtest.c (mymain): Likewise.

storage: use valid XML for awkward volume names $ touch /var/lib/libvirt/images/'a<b>c' $ virsh pool-refresh default $ virsh vol-dumpxml 'a<b>c' default | head -n2 <volume> <name>a<b>c</name> Oops. That's not valid XML. And when we fix the XML generation, it fails RelaxNG validation. I'm also tired of seeing <key>(null)</key> in the example output for volume xml; while we used NULLSTR() to avoid a NULL deref rather than relying on glibc's printf extension behavior, it's even better if we avoid the issue in the first place. But this requires being careful that we don't invalidate any storage backends that were relying on key being unassigned during virStoragVolCreateXML[From]. I would have split this into two patches (one for escaping, one for avoiding <key>(null)</key>), but since they both end up touching a lot of the same test files, I ended up merging it into one. Note that this patch allows pretty much any volume name that can appear in a directory (excluding . and .. because those are special), but does nothing to change the current (unenforced) RelaxNG claim that pool names will consist only of letters, numbers, _, -, and +. Tightening the C code to match RelaxNG patterns and/or relaxing the grammar to match the C code for pool names is a task for another day (but remember, we DID recently tighten C code for domain names to exclude a leading '.'). * src/conf/storage_conf.c (virStoragePoolSourceFormat) (virStoragePoolDefFormat, virStorageVolTargetDefFormat) (virStorageVolDefFormat): Escape user-controlled strings. (virStorageVolDefParseXML): Parse key, for use in unit tests. * src/storage/storage_driver.c (storageVolCreateXML) (storageVolCreateXMLFrom): Ensure parsed key doesn't confuse volume creation. * docs/schemas/basictypes.rng (volName): Relax definition. * tests/storagepoolxml2xmltest.c (mymain): Test it. * tests/storagevolxml2xmltest.c (mymain): Likewise. * tests/storagepoolxml2xmlin/pool-dir-naming.xml: New file. * tests/storagepoolxml2xmlout/pool-dir-naming.xml: Likewise. * tests/storagevolxml2xmlin/vol-file-naming.xml: Likewise. * tests/storagevolxml2xmlout/vol-file-naming.xml: Likewise. * tests/storagevolxml2xmlout/vol-*.xml: Fix fallout.

New XML attributes for storage pool source adapter This introduces 4 new attributes for storage pool source adapter. E.g. <adapter type='fc_host' parent='scsi_host5' wwnn='20000000c9831b4b' wwpn='10000000c9831b4b'/> Attribute 'type' can be either 'scsi_host' or 'fc_host', and defaults to 'scsi_host' if attribute 'name' is specified. I.e. It's optional for 'scsi_host' adapter, for back-compat reason. However, mandatory for 'fc_host' adapter and any new future adapter types. Attribute 'parent' is to specify the parent for the fc_host adapter. * docs/formatstorage.html.in: - Add documents for the 4 new attrs * docs/schemas/storagepool.rng: - Add RNG schema * src/conf/storage_conf.c: - Parse and format the new XMLs * src/conf/storage_conf.h: - New struct virStoragePoolSourceAdapter, replace "char *adapter" with it; - New enum virStoragePoolSourceAdapterType * src/libvirt_private.syms: - Export TypeToString and TypeFromString * src/phyp/phyp_driver.c: - Replace "adapter" with "adapter.data.name", which is member of the union of the new struct virStoragePoolSourceAdapter now. Later patch will add the checking, as "adapter.data.name" is only valid for "scsi_host" adapter. * src/storage/storage_backend_scsi.c: - Like above * tests/storagepoolxml2xmlin/pool-scsi-type-scsi-host.xml: * tests/storagepoolxml2xmlin/pool-scsi-type-fc-host.xml: - New test for 'fc_host' and "scsi_host" adapter * tests/storagepoolxml2xmlout/pool-scsi.xml: - Change the expected output, as the 'type' defaults to 'scsi_host' if 'name" specified now * tests/storagepoolxml2xmlout/pool-scsi-type-scsi-host.xml: * tests/storagepoolxml2xmlout/pool-scsi-type-fc-host.xml: - New test * tests/storagepoolxml2xmltest.c: - Include the test

storage: Introduce 'managed' for the fchost parent https://bugzilla.redhat.com/show_bug.cgi?id=1160926 Introduce a 'managed' attribute to allow libvirt to decide whether to delete a vHBA vport created via external means such as nodedev-create. The code currently decides whether to delete the vHBA based solely on whether the parent was provided at creation time. However, that may not be the desired action, so rather than delete and force someone to create another vHBA via an additional nodedev-create allow the configuration of the storage pool to decide the desired action. During createVport when libvirt does the VPORT_CREATE, set the managed value to YES if not already set to indicate to the deleteVport code that it should delete the vHBA when the pool is destroyed. If libvirtd is restarted all the memory only state was lost, so for a persistent storage pool, use the virStoragePoolSaveConfig in order to write out the managed value. Because we're now saving the current configuration, we need to be sure to not save the parent in the output XML if it was undefined at start. Saving the name would cause future starts to always use the same parent which is not the expected result when not providing a parent. By not providing a parent, libvirt is expected to find the best available vHBA port for each subsequent (re)start. At deleteVport, use the new managed value to decide whether to execute the VPORT_DELETE. Since we no longer save the parent in memory or in XML when provided, if it was not provided, then we have to look it up.

storage: Introduce parentaddr into virStoragePoolSourceAdapter Between reboots and kernel reloads, the SCSI host number used for SCSI storage pools may change requiring modification to the storage pool XML in order to use a specific SCSI host adapter. This patch introduces the "parentaddr" element and "unique_id" attribute for the SCSI host adapter in order to uniquely identify the adapter between reboots and kernel reloads. For now the goal is to only parse and format the XML. Both will be required to be provided in order to uniquely identify the desired SCSI host. The new XML is expected to be as follows: <adapter type='scsi_host'> <parentaddr unique_id='3'> <address domain='0x0000' bus='0x00' slot='0x1f' func='0x2'/> </parentaddr> </adapter> where "parentaddr" is the parent device of the SCSI host using the PCI address on which the device resides and the value from the unique_id file for the device. Both the PCI address and unique_id values will be used to traverse the /sys/class/scsi_host/ directories looking at each link to match the PCI address reformatted to the directory link format where "domain:bus:slot:function" is found. Then for each matching directory the unique_id file for the scsi_host will be used to match the unique_id value in the xml. For a PCI address listed above, this will be formatted to "0000:00:1f.2" and the links in /sys/class/scsi_host will be used to find the host# to be used for the 'scsi_host' device. Each entry is a link to the /sys/bus/pci/devices directories, e.g.: % ls -al /sys/class/scsi_host/host2 lrwxrwxrwx. 1 root root 0 Jun 1 00:22 /sys/class/scsi_host/host2 -> ../../devices/pci0000:00/0000:00:1f.2/ata3/host2/scsi_host/host2 % cat /sys/class/scsi_host/host2/unique_id 3 The "parentaddr" and "name" attributes are mutually exclusive to identify the SCSI host number. Use of the "parentaddr" element will be the preferred mechanism. This patch only supports to parse and format the XMLs. Later patches will add code to find out the scsi host number.
