Using the PE loader, we can patch our own 42 * versions of the NDIS routines into a given Windows driver module and 43 * convince the driver that it is in fact running on Windows. 44 * 45 * We provide a table of all our implemented NDIS routines which is patched 46 * into the driver object code. All our exported routines must use the 47 * _stdcall calling convention, since that's what the Windows object code 48 * expects. 49 */ 50 51 52#include <sys/param.h> 53#include <sys/types.h> 54#include <sys/errno.h> 55 56#include <sys/callout.h> 57#include <sys/kernel.h> 58#include <sys/systm.h> 59#include <sys/malloc.h> 60#include <sys/lock.h> 61#include <sys/mutex.h> 62#include <sys/socket.h> 63#include <sys/sysctl.h> 64#include <sys/timespec.h> 65#include <sys/smp.h> 66#include <sys/queue.h> 67#include <sys/taskqueue.h> 68 69#include <net/if.h> 70#include <net/if_arp.h> 71#include <net/ethernet.h> 72#include <net/if_dl.h> 73#include <net/if_media.h> 74 75#include <machine/bus_memio.h> 76#include <machine/bus_pio.h> 77#include <machine/bus.h> 78#include <machine/resource.h> 79 80#include <sys/bus.h> 81#include <sys/rman.h> 82 83#include <machine/stdarg.h> 84 85#include <net80211/ieee80211_var.h> 86#include <net80211/ieee80211_ioctl.h> 87 88#include <dev/pci/pcireg.h> 89#include <dev/pci/pcivar.h> 90 91#include <compat/ndis/pe_var.h> 92#include <compat/ndis/resource_var.h> 93#include <compat/ndis/ntoskrnl_var.h> 94#include <compat/ndis/ndis_var.h> 95#include <compat/ndis/cfg_var.h> 96#include <dev/if_ndis/if_ndisvar.h> 97 98#define __stdcall __attribute__((__stdcall__)) 99#define FUNC void(*)(void) 100 101static struct mtx ndis_interlock;
