[Xen-devel] BSOD in GPLPV rev928 in xennet.sys



Hello James,

on Windows 2008 R2 SP1 I get a BSOD on GPLPV setup. After some analyzing
I found that it is a "null ptr read" in the call to
NdisFreeToNPagedLookasideList. File is xennet6_tx.c line 336.

      length = XenNet_QueryData(&pi, coalesce_remaining);
      va = NdisBufferVirtualAddressSafe(pi.curr_mdl, LowPagePriority);
      if (!va)
      {
        KdPrint((__DRIVER_NAME "     failed to map buffer va - partial
send\n"));
        coalesce_remaining = 0;
        remaining -= min(PAGE_SIZE, remaining);
NdisFreeToNPagedLookasideList(&xi->tx_lookaside_list, coalesce_buf);
      }
      else
      {

Regards Andreas
