TO DO LIST----------
1. Report NIC Friendly Name - Add szFriendlyName to CfgUtilGetStaticIpAddresses Friendly name: "NetConnectionID" Note: Adapter name is "Name" Check out other properties of cimv2\Win32_NetworkAdapter - Make "tprov niclist" report reporting friendly names and first ip addr. Format: {B2CD5533-5091-4F49-B80F-A07844B14209} 10.0.0.1/255.0.0.0 "1394 Adapter" - Add (fIncludeDisabled) flag to NicList. - Add friendly name and device-state to EXTENDED_CONFIGURATION structure - Dump this information in display_config (if non-NULL) - Implement filling out this information in EXTENDED_CONFIGURATION structure - Add friendly name to MOF - Implement reporting this in wmiupdate
2. Impliment CompatibleNicList in WMI - Add GetCompatibleAdapterGuids method to MOF. - Add support for wminiclist in tprov
3. Implement popup if no non-nlb adapters left in nlbmgr.exe
4. Change ip address to bind string in connect-dialog, first ping for the address, etc...
3. Demonstrate fundamental plumbing is working: x Modify existing test to optionally go through WMI -- get rid of nlbhost class (nlbhost.cpp) x Verify we can get partial input and output parameters for GetConfig x Implement and test GetClusterConfig with partial params x Re-test local (non-wmi) functionality, including bind/unbind, change IPs x Implement QueryUpdate and UpdateConfig x test UpdateConfig with partial params
- Implement and test getting port rules information - Implement and test settings port rule information - Implement and test getting full information - Implement and test setting full information 4. Hook into nlb manager
4. Add "partial-update" semantics New parameter: BOOL PartialUpdate OPTIONAL parameter Generation -- if specified, we'll verify that the Generation matches the current generation. parameter value NULL === don't change port rules: require the following property on each PR for partial-updates: action=[ADD|DELETE|UPDATE] IP addresses: require the ip address to be prefixed by "add:" "delete:" or "update:" (latter for changing subnet masks) UI: add:{10.1.1.3} delete:{10.1.1.3, 255.0.0} update:{10.1.1.3, 255.0.0}
EXAMPLE 1: PartialUpdate=TRUE PortRules="action=update ip=10.1.1.3 start=80 end=288 weight=20 ...."
EXAMPLE 2: PartialUpdate=TRUE IpAddresses="add:10.0.0.1/255.255.0.0", "delete:10.0.0.2" Generation=85. Switch from events to using two mutexes6. Explicitly report the following errors - other update pending - netcfg write lock held7. Use resource strings8. Use internal constants for error codes and literal strings9. Follow up on WMI SDK errors -- DaveIce WBEM_E_SERVER_NOT_FOUND -- where is this defined. 0x800706bf -- no definition in any header (and I checked in index2a with interesting results), recoverable error. 0x80070767 -- no defn 0x80070005 -- no defn------------------------------------
"Persistant" state for a particular NIC is mainained as a (for now)volatile key under SYSTEM\CurrentControlSet\Services\WLBS\ConfigurationHistory\{GUID}Under this GUID, there is are a set of reg-binary values (which are lighter weight than keys). They value-name is the generation number, and the value is a struct concatenated with a log. The struct has the format:typedef struct { UINT Version; UINT HeaderSize; UINT Generation; UINT CompletionCode; UINT OffsetToLog; // from start of this structure UINT LogSize; // 0 == no log UINT Reserved1; UINT Reserved2;};
swprintf (reg_path, L"SYSTEM\\CurrentControlSet\\Services\\WLBS\\Parameters\\Interface\\%s", szAdapterGuid);

04/10/2001 JosephJ Mutex vs Event vs Registry Finally settled on a named event because: 1. Needs to recover from a process crash (so can't use registry) 2. Needs to be cross process -- so must used named object 3. Need to "acquire" in one thread and "release" in another -- so can't use mutex. The auto-reset event is normally signalled. It is non-signalled whenever an operation is pending. It is manually set back to signalled whenever the operation is completed.bp tprov!NlbConfigurationUpdate__DoUpdate bp tprov!NlbConfigurationUpdate__s_AsyncUpdateThreadProc -------Sean, you can do this semi-automatically by creating a new and temporary tree just for the merging process.
So for example, create a new directory driver2 in the private tree (or your scratch depot) and checkin the latest netvbl2 checked-in sources..From one enlistment, open the files for edit, and copy over your BDA privates (but dont checkin).From a second enlistment, open the files for edit, and copy over the latest privates from the private tree (this has virtual cluster support), and check this in.Go back to the first enlistment and resolve.-------

04/25/2001 JosephJ Adding/removing IP addresses. Binding/Re-binding NLB: we require the explicit list of IP addresses to be specified. We'll check that (a) dedicated ip address, if specified, is first. (b) cluster_vip and subnet mask match are present. (c) vips for any per-ip port rules are present. We honor the specified order of ip addresses. Unbinding NLB: We set the specified list of ip addresses. If NULL, we'll switch the adapter to DHCP, which could take a while.

Static methods -- callingA method may or may not be static. Static methods are designated by the presence of the Static qualifier on their definition. Static methods are executed against a class, not a particular instance of that class. The path specified to a method execution API for a static method must, therefore, be a class name. Non-static methods are executed against a particular instance of a class. The path specified to a method execution for a non-static method must, therefore, be an instance path
