Malloc, absolutely not, unless you want to write your own, and manage your
own heap. However, you can use ExAllocatePool, but you will need a source
module that you link with ntddk.h, and then call a function wrapper that
allocates and frees memory.

No.

In miniports, all memory is assumed to be:

  • per-request
    or
  • per-LUN
    or
  • per-device.

Set the Device/Lu/SRB extension sizes as necessary in your miniport parameters structure, and SCSIPORT will pre-allocate this memory
for you.
Note that for busmaster miniports, SRB and device extensions are DMAble, while LUN extension is not.
