open-vm-tools/send_vmbackup_event_generic_manifest.patch
Kirk Allan 062860c7b1 Accepting request 672900 from home:kallan:branches:Virtualization:VMware 
- Link VGAuthService to libxmlsec1 rather than libxml-security-c in SLE
  products where available. (bsc#1122435)
- Add patches to correct and/or improve handling of certain quiesced snapshot
  failures (bsc#1124397).
  + no_manifest_on_aborted_snapshot.patch
    Don't send a backup manifest when aborting a Linux quiesced snapshot.
  + vmtoolsd_bailout_on_rpc_errors.patch
    Bail out vmtoolsd early when there are RPC errors.
  + send_vmbackup_event_generic_manifest.patch
    Always send VMBACKUP_EVENT_GENERIC_MANIFEST during quiesced snapshots.
  + include_log_h_for_g_info.patch
    Include vmware/tools/log.h to define g_info.

- Update vmtoolsd.service to support cloud-init customization by default  
  by adding "DefaultDependencies=no" and "Before=cloud-init-local.service"
  to the [Unit] section of vmtoolsd.service (bsc#1121964) .
- Copyright year updated in spec file.

commit c31710b3942f48b1c11ebde36f34e7e159d1cbf0
Author: Oliver Kurth <okurth@vmware.com>
Date: Tue Jan 29 17:24:44 2019 -0800
Always send VMBACKUP_EVENT_GENERIC_MANIFEST during quiesced snapshots.
vSphere 6.7 added a host-side interface that allows VMTools to send
a "generic" backup manifest during a quiesced snapshot on Linux guests.
VMTools 10.2.0 or later tries to notify the host of the backup manifest
file through a vmbackup event message VMBACKUP_EVENT_GENERIC_MANIFEST.
If the host is unable to field the message, then VMTools logs the
failure and then continues with the quiesced snapshot in the older
fashion, without the backup manifest.
An earlier change attempted to reduce the amount of logging done when
running on older hosts that don't support VMBACKUP_EVENT_GENERIC_MANIFEST
by detecting when sending VMBACKUP_EVENT_GENERIC_MANIFEST fails and
not sending the message again for subsequent quiesced snapshots.
However, subsequent stress testing has uncovered problems with this
approach when running on newer hosts; specifically, errors may sometimes
be encountered on newer hosts when sending VMBACKUP_EVENT_GENERIC_MANIFEST.
Therefore this change backs out that earlier change.
Note that the need to solve the problem that that earlier change was
intended to solve has been reduced because support for
VMBACKUP_EVENT_GENERIC_MANIFEST has been backported to vSphere 6.5
P03, which is available, and vSphere 6.0 P08, which is scheduled for
release later this year. ESXi 5.5 is out of general support.
This change also addresses an issue that surfaced when testing on a
host without support for VMBACKUP_EVENT_GENERIC_MANIFEST.
If VMTools fails to send VMBACKUP_EVENT_GENERIC_MANIFEST, the quiesced
snapshot operation will be aborted rather than continuing as it should.
To address this, create a new function, VmBackup_SendEventNoAbort,
which does not abort the quiesced snapshot on failure, and call that
function rather than VmBackup_SendEvent when sending
VMBACKUP_EVENT_GENERIC_MANIFEST.
