The VBR (volume boot sector) contains a structure called BPB (bios parameter block) that describes the disk and the partition. The HiddenSectors member contains the number of the first sector of the partition. This is used by the VBR code to load the secondary sector containing additional boot code that is located at secor 14 relative to the partition start. Previously we were copying the BPB (plus additionally the OemName, which makes no sense) from the old VBR. Now Linux is a bit lame and doesn't put the correct value into the HiddenSectors field. Instead it sets it to the number of sectors per track which seems to be the default value. When now the linux partition manager decides to do a non standard partitioning, aligning the partition to 0x800, then the VBR fails to load it's 2nd sector. Fix this by correcting the value in the BPB with the value from the partition info.
See issue #2733 for more details.

- Start rewrite of usbhub driver using the old and dead usbhub driver in trunk.
- Implement QueryRootHub for sending USB request to miniport driver.
- Implement new IRP_MN_START_DEVICE.
Get the roothubs PDO and FDO and forward the start device down to start the PDO.
Get USBDI and HUB interfaces. Set all ports as returned by DCI GetExtendedHubInformation to powered and reset.
- Temporary add some usb specific defines until header is fixed.
- Fix Formatting.
svn path=/trunk/; revision=48705
- Fix flags settings for PortStatus and PortChange so that the correct flags are set when hub driver sets/requests them.
- Use FastMutex to protect access to async queue and frame list.
- For USB CONFIG DESC, Check the output buffer size before attempting to write all configuration descriptors.
- Fix a bug that caused bmRequestType to be incorret value when requesting configuration and string descriptors.
- Modify some debugging to make it easier to see debug messages from usbhub driver.
svn path=/trunk/; revision=48704
- Add the option to write only the VBR so FreeLoader can easily be chain loaded by GRUB or another boot loader
- Dedicated to James Tabor :)
svn path=/trunk/; revision=48703
- Remove code that was corrupting disk data and causing setup to fail in rare cases
- Write the MBR in all cases (Windows setup behavior too)
- We can overwrite GRUB and LILO now but we still can't boot because we have trouble reading the partition table if it was made in Linux

[NTOS]: In the process, fix bugs in the Event dispatcher code that used Win32 EVENT_TYPE instead of NT KOBJECTS enumeration.
[NTOS]: Fix a bug in ObpInsertHandleCount, where the object access check was being done with the previous mode, instead of honoring the probe mode, which is defined by OBJ_FORCE_ACCESS_CHECK.
[NTOS]: Fix a bug in a section function which was always returning STATUS_SUCCESS, now it returns the result of the previous Status = function assignment. If this isn't desired, then don't check for the Status anymore.
[NTOS]: Note that MDL code does not support SkipBytes argument. If it is used, MDL could be invalid.
[NTOS]: Add checks for VerifierAllocation and set it when needed (WIP).
[NTOS]: Clarify what _WORKING_LINKER_ is, and the legal risks in continuing to use a linker that builds non-Microsoft drivers when used with headers whose EULA specify that they can only be used for Microsoft drivers.

- Check for a shutdown connection that we missed a few times
- Remove some junk and stop playing with flags behind oskit's back
- Fix an invalid parameter check
- Enable a check to ensure that accept doesn't get called for a socket that isn't listening
- Use the queue manipulation function instead of manually changing the queue
- Signal that we accepted/connected a socket
[IP]
- Set the network mask and destination address in TCPGetInterfaceData

[CDFS]
- Several fixes for directory information query.
- Fixed a null access memory under certain circumstances.
- Added support for media ejection.
[FASTFAT]
- Fixed calls to CcMapData(), CcPinRead().
- Fixed an endless loop in FCB management under certain circumstances.
[NTOSKRNL]
- Fixed wrong prototype for IopParseDevice().

[NTOS]: Add support for protected freed nonpaged pool. This is controlled through MmProtectFreedNonPagedPool, which is initialized based on a registry value (see cmdata.c). This is not "Special Pool", but a useful debugging feature Windows implements that we now have too, since I noticed a lot of mj's work was with freed pool access.
NB. It's 3AM and I have not tested this, it should be off in trunk by default, you'll need to try turning it on and testing it. Hope it helps.

- Working with Pierre Schweitzer for yet another NonPaged Pool corruption fix. When copying VolumeLabel the VolumeLabelLength is in Unicode, so theres no need to mulitply it by size of WCHAR.

Modified version of r48640:
- update the NodeHint to the root node when deleting a node
- remove this code from MmCleanProcessAddressSpace
svn path=/trunk/; revision=48642
- When a node is removed, check the NodeHint of the table to see if it matches the one being removed. If so update the NodeHint to the PreviousNode. FIxes VAD corruption messages.

- Mouse messages can be sent before the desktop is initialized. Check for this and return false if its not. FIxes assert when moving mouse before desktop is up.
svn path=/trunk/; revision=48636
- Fix a check when queuing the mouse packet. Check that the buffer size (MouseInBuffer) is not greater or equal to MouseDataQueueSize. Fixes a NonPagedPool corruption that occurs when the mouse is moved before the desktop window is up and running.

- When deleting a Process remove the Process from the MmProcessList. Fixes random NonPaged Pool corruptions. Thanks aicom for assistance.

- Acquire and Release RundownProtection on the Parent Pocess not the newly created Pcess when setting the SectionObject.
svn path=/trunk/; revision=48631
- Rework EngSetPointerShape, to first allocate the neccessary surfaces, before deleting the old ones. Also check in IntShowMousePointer if a saving surface is present. This way a failure to allocate a surface will not result in a crash, but keep the old mouse pointer.
See issue #5402 for more details.

- Only tell the caller how much we sent/received if it completed successfully
- Set SO_DONTROUTE on accepted sockets too
- Disable the core routing code
- Make our MSS calculation much better by sharing the existing code
svn path=/trunk/; revision=48628
- Fix to PpSetCustomTargetEvent(), not to make caller wait forever in case it provided an event it waits for
- Patch by Pierre Schweitzer
svn path=/trunk/; revision=48626
- Prevent multiple wakeups for the same event which caused nasty problems for the SEL_FIN event because we dereferenced our connection context 3 times which not only caused the connection endpoint to be freed while holding its spin lock but made the reference count negative
[TCPIP]
- Disassociate the address file from the connection endpoint before dereferencing/closing it to avoid a double dereference of the address file (not as harmful in this case as in the connection endpoint case)
[IP]
- Dereference the connection endpoint again if it was associated with an address file as the connection endpoint to fix a reference leak

Add bugs_regtest. This can be used to create testcases / regression tests for already fixed bugs. I added a first test for bug 3481
svn path=/trunk/; revision=48615
- Rewrite MiFindEmptyAddressRangeDownTree. The old implementation's "most awesome loop" duplicated both the initialization and the interation steps. It was also overcomplicated. The new implementation additionally returns the parent for the following table insertion, so this doesnt need to be done in an extra search. The return value is changed from NTSTATUS to TABLE_SEARCH_RESULT
- Modify MiInsertNode to accept a parent and TABLE_SEARCH_RESULT instead of searching for a free location.
- Modify MiCreatePebOrTeb to make use of the new features
- Handle failed allocation of the PEB/TEB
- Fixes a failed assertion that Olaf got
- I tested this code quite some time and no problems were found

Move the allocation of the vis region of the DC to a later position, so that all mandatory fields are initialized before we try to delete the DC in failure case. Fixes yet another possible crash.
