      qemu: support disk filenames with comma · 6e0ff1d4
      Eric Blake 提交于
      If there is a disk file with a comma in the name, QEmu expects a double
      comma instead of a single one (e.g., the file "virtual,disk.img" needs
      to be specified as "virtual,,disk.img" in QEmu's command line). This
      patch fixes libvirt to work with that feature. Fix RHBZ #801036.

      virNetworkDNSHostsDefParseXML was calling VIR_ALLOC(def->hosts) if

      VIR_REALLOC_N is called a few lines further down, prior to any use of

      util: consolidate duplicated error messages in pci.c · b8e47850

      This is nearly identical to an earlier patch for virnetlink.c.

      that are compiled when the platform isn't linux. Each of these
      functions had an almost identical message, differing only in the
      function name included in the message. Since log messages already
      contain the function name, we can just define a const char* with the
      common part of the string, and use that same string for all the log

      util: standardize return from functions calling virNetlinkCommand · 0208face
      Laine Stump 提交于
      There are several functions that call virNetlinkCommand, and they all
      follow a common pattern, with three exit labels: err_exit (or
      cleanup), malformed_resp, and buffer_too_small. All three of these
      labels do their own cleanup and have their own return. However, the
      malformed_resp label usually frees the same items as the
      cleanup/err_exit label, and the buffer_too_small label just doesn't
      free recvbuf (because it's known to always be NULL at the time we goto
      buffer_too_small.
      
      In order to simplify and standardize the code, I've made the following
      changes to all of these functions:
      
      1) err_exit is replaced with the more libvirt-ish "cleanup", which
         makes sense because in all cases this code is also executed in the
         case of success, so labelling it err_exit may be confusing.
      
      2) rc is initialized to -1, and set to 0 just before the cleanup
         label. Any code that currently sets rc = -1 is made to instead goto
         cleanup.
      
      3) malformed_resp and buffer_too_small just log their error and goto
         cleanup. This gives us a single return path, and a single place to
         free up resources.
      
      4) In one instance, rather then logging an error immediately, a char*
         msg was pointed to an error string, then goto cleanup (and cleanup
         would log an error if msg != NULL). It takes no more lines of code
         to just log the message as we encounter it.
      
      This patch should have 0 functional effects.

      util: eliminate device object leaks related to virDomain*Remove*() · f985773d
      Laine Stump 提交于
      There are several functions in domain_conf.c that remove a device
      object from the domain's list of that object type, but don't free the
      object or return it to the caller to free. In many cases this isn't a
      problem because the caller already had a pointer to the object and
      frees it afterward, but in several cases the removed object was just
      left floating around with no references to it.
      
      In particular, the function qemuDomainDetachDeviceConfig() calls
      functions to locate and remove net (virDomainNetRemoveByMac), disk
      (virDomainDiskRemoveByName()), and lease (virDomainLeaseRemove())
      devices, but neither it nor its caller qemuDomainModifyDeviceConfig()
      ever obtain a pointer to the device being removed, much less free it.
      
      This patch modifies the following "remove" functions to return a
      pointer to the device object being removed from the domain device
      arrays, to give the caller the option of freeing the device object
      using that pointer if needed. In places where the object was
      previously leaked, it is now freed:
      
        virDomainDiskRemove
        virDomainDiskRemoveByName
        virDomainNetRemove
        virDomainNetRemoveByMac
        virDomainHostdevRemove
        virDomainLeaseRemove
        virDomainLeaseRemoveAt
      
      The functions that had been leaking:
      
        libxlDomainDetachConfig - leaked a virDomainDiskDef
        qemuDomainDetachDeviceConfig - could leak a virDomainDiskDef,
                                  a virDomainNetDef, or a
                                  virDomainLeaseDef

      qemu: don't 'remove' hostdev objects from domain if operation fails · b59e5984
      Laine Stump 提交于
      There were certain paths through the hostdev detach code that could
      lead to the lower level function failing (and not removing the object
      from the domain's hostdevs list), but the higher level function
      free'ing the hostdev object anyway. This would leave a stale
      hostdevdef pointer in the list, which would surely cause a problem
      eventually.
      
      This patch relocates virDomainHostdevRemove from the lower level
      functions qemuDomainDetachThisHostDevice and
      qemuDomainDetachHostPciDevice, to their caller
      qemuDomainDetachThisHostDevice, placing it just before the call to
      virDomainHostdevDefFree. This makes it easy to verify that either both
      operations are done, or neither.
      
      NB: The "dangling pointer" part of this problem was introduced in
      commit 13d5a6, so it is not present in libvirt versions prior to
      0.9.9. Earlier versions would return failure in certain cases even
      though the the device object was removed/deleted, but the removal and
      deletion operations would always both happen or neither.

      There are special stub versions of all public functions in this file

      isn't linux. Each of these functions had two almost identical message,

      messages already contain the function name, we can just define a const
      char* with the common part of the string, and use that same string for
      all the log messages.
      
      Also, rather than doing #if defined ... #else ... #endif *inside the
      error log macro invocation*, this patch does #if defined ... just
      once, using it to decide which single string to define. This turns the
      error log in each function from 6 lines, to 1 line.

      qemu: Don't parse device twice in attach/detach · 1e0534a7

      Some members are generated during XML parse (e.g. MAC address of

      are plugging a device both to persistent and live config,
      we parse given XML twice: first time for live, second for config.
      This is wrong then as the second time we are not guaranteed
      to generate same values as we did for the first time.
      To prevent that we need to create a copy of DeviceDefPtr;
      This is done through format/parse process instead of writing
      functions for deep copy as it is easier to maintain:
      adding new field to any virDomain*DefPtr doesn't require change

      In the past, we have created some virsh options with less-than-stellar
      names.  For back-compat reasons, those names must continue to parse,
      but we don't want to document them in help output.  This introduces
      a new option type, an alias, which points to a canonical option name
      later in the option list.
      
      I'm actually quite impressed that our code has already been factored
      to do all option parsing through common entry points, such that I
      got this added in relatively few lines of code!
      
      * tools/virsh.c (VSH_OT_ALIAS): New option type.
      (opts_echo): Hook up an alias, for easy testing.
      (vshCmddefOptParse, vshCmddefHelp, vshCmddefGetOption): Allow for
      aliases.
      * tools/virsh.pod (NOTES): Document promise of back-compat.
      * tests/virshtest.c (mymain): Test new feature.

      xml: use better types for memory values · 4888f0fb
      Eric Blake 提交于
      Using 'unsigned long' for memory values is risky on 32-bit platforms,
      as a PAE guest can have more than 4GiB memory.  Our API is
      (unfortunately) locked at 'unsigned long' and a scale of 1024, but
      the rest of our system should consistently use 64-bit values,
      especially since the previous patch centralized overflow checking.
      
      * src/conf/domain_conf.h (_virDomainDef): Always use 64-bit values
      for memory.  Change hugepage_backed to a bool.

      xml: use long long internally, to centralize overflow checks · 73b99771
      Eric Blake 提交于
      On 64-bit platforms, unsigned long and unsigned long long are
      identical, so we don't have to worry about overflow checks.
      On 32-bit platforms, anywhere we narrow unsigned long long back
      to unsigned long, we have to worry about overflow; it's easier
      to do this in one place by having most of the code use the same
      or wider types, and only doing the narrowing at the last minute.
      Therefore, the memory set commands remain unsigned long, and
      the memory get command now centralizes the overflow check into
      libvirt.c, so that drivers don't have to repeat the work.
      
      This also fixes a bug where xen returned the wrong value on
      failure (most APIs return -1 on failure, but getMaxMemory
      must return 0 on failure).
      
      * src/driver.h (virDrvDomainGetMaxMemory): Use long long.

      xml: drop unenforced minimum memory limit from RNG · 1b1402b9
      Eric Blake 提交于
      The test domain allows <memory>0</memory>, but the RNG was stating
      that memory had to be at least 4096000 bytes.  Hypervisors should
      enforce their own limits, rather than complicating the RNG.
      
      Meanwhile, some copy and paste had introduced some fishy constructs
      in various unit tests.
      
      * docs/schemas/domaincommon.rng (memoryKB, memoryKBElement): Drop
      limit that isn't enforced in code.

      storage: support more scaling suffixes · 2e148612
      Eric Blake 提交于
      Disk manufacturers are fond of quoting sizes in powers of 10,
      rather than powers of 2 (after all, 2.1 GB sounds larger than
      2.0 GiB, even though the exact opposite is true).  So, we might
      as well follow coreutils' lead in supporting three types of
      suffix: single letter ${u} (which we already had) and ${u}iB
      for the power of 2, and ${u}B for power of 10.
      
      Additionally, it is impossible to create a file with more than
      2**63 bytes, since off_t is signed (if you have enough storage
      to even create one 8EiB file, I'm jealous).  This now reports
      failure up front rather than down the road when the kernel
      finally refuses an impossible size.
      
      * docs/schemas/basictypes.rng (unit): Add suffixes.
      * src/conf/storage_conf.c (virStorageSize): Use new function.
      * docs/formatstorage.html.in: Document it.
