* Unify all the wifi *_ioctl routinesAndrew Thompson2008-05-011-12/+50
| | | | | | | | | | | | | | | | | - Limit grabbing the lock to SIOCSIFFLAGS. - Move ieee80211_start_all() to SIOCSIFFLAGS. - Remove SIOCSIFMEDIA as it is not useful. - Limit ether_ioctl to only SIOCGIFADDR. SIOCSIFADDR and SIOCSIFMTU have no affect as there is no input/output path in the vap parent. The vap code will handle the reinit of the mac address changes. - Split off ndis_ioctl_80211 as it was getting too different to wired devices. This fixes a copyout while locked and a lock recursion.

* When ndis_attach() runs, it has to very briefly initialize the cardBill Paul2006-02-041-14/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | in order to query the underlying Windows driver for the station address and some other properties. There is a slim chance that the card may receive a packet and indicate it up to us before ndis_attach() can call ndis_halt_nic(). This is bad, because both the softc structure and the ifnet structure aren't fully initialized yet: many pointers are still NULL, so if we make it into ndis_rxeof(), we will panic. To fix this, we need to do the following: - Move the calls to IoAllocateWorkItem() to before the call to ndis_init_nic(). - Move the initialization of the RX DPC and status callback function pointers to before ndis_init_nic() as well. - Modify ndis_rxeof() to check if the IFF_DRV_RUNNING flag is set. If it isn't, we return any supplied NDIS_PACKETs to the NIC without processing them.

* The latest version of the Intel 2200BG/2915ABG driver (9.0.0.3-9) fromBill Paul2005-11-061-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel's web site requires some minor tweaks to get it to work: - The driver seems to have been released with full WMI tracing enabled, and makes references to some WMI APIs, namely IoWMIRegistrationControl(), WmiQueryTraceInformation() and WmiTraceMessage(). Only the first one is ever called (during intialization). These have been implemented as do-nothing stubs for now. Also added a definition for STATUS_NOT_FOUND to ntoskrnl_var.h, which is used as a return code for one of the WMI routines. - The driver references KeRaiseIrqlToDpcLevel() and KeLowerIrql() (the latter as a function, which is unusual because normally KeLowerIrql() is a macro in the Windows DDK that calls KfLowewIrql()). I'm not sure why these are being called since they're not really part of WDM. Presumeably they're being used for backwards compatibility with old versions of Windows. These have been implemented in subr_hal.c. (Note that they're _stdcall routines instead of _fastcall.) - When querying the OID_802_11_BSSID_LIST OID to get a BSSID list, you don't know ahead of time how many networks the NIC has found during scanning, so you're allowed to pass 0 as the list length. This should cause the driver to return an 'insufficient resources' error and set the length to indicate how many bytes are actually needed. However for some reason, the Intel driver does not honor this convention: if you give it a length of 0, it returns some other error and doesn't tell you how much space is really needed. To get around this, if using a length of 0 yields anything besides the expected error case, we arbitrarily assume a length of 64K. This is similar to the hack that wpa_supplicant uses when doing a BSSID list query. Notes: svn path=/head/; revision=152136
* Tests with my dual Opteron system have shown that it's possibleBill Paul2005-11-021-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for code to start out on one CPU when thunking into Windows mode in ctxsw_utow(), and then be pre-empted and migrated to another CPU before thunking back to UNIX mode in ctxsw_wtou(). This is bad, because then we can end up looking at the wrong 'thread environment block' when trying to come back to UNIX mode. To avoid this, we now pin ourselves to the current CPU when thunking into Windows code. Few other cleanups, since I'm here: - Get rid of the ndis_isr(), ndis_enable_interrupt() and ndis_disable_interrupt() wrappers from kern_ndis.c and just invoke the miniport's methods directly in the interrupt handling routines in subr_ndis.c. We may as well lose the function call overhead, since we don't need to export these things outside of ndis.ko now anyway. - Remove call to ndis_enable_interrupt() from ndis_init() in if_ndis.c. We don't need to do it there anyway (the miniport init routine handles it, if needed). - Fix the logic in NdisWriteErrorLogEntry() a little. - Change some NDIS_STATUS_xxx codes in subr_ntoskrnl.c into STATUS_xxx codes. - Handle kthread_create() failure correctly in PsCreateSystemThread().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Change ndis_return() from a DPC to a workitem so that it doesn't run at DISPATCH_LEVEL (with the dispatcher lock held). - In if_ndis.c, submit packets to the stack via (*ifp->if_input)() in a workitem instead of doing it directly in ndis_rxeof(), because ndis_rxeof() runs in a DPC, and hence at DISPATCH_LEVEL. This implies that the 'dispatch level' mutex for the current CPU is being held, and we don't want to call if_input while holding any locks. - Reimplement IoConnectInterrupt()/IoDisconnectInterrupt(). The original approach I used to track down the interrupt resource (by scanning the device tree starting at the nexus) is prone to problems when two devices share an interrupt. (E.g removing ndis1 might disable interrupts for ndis0.) The new approach is to multiplex all the NDIS interrupts through a common internal dispatcher (ntoskrnl_intr()) and allow IoConnectInterrupt()/IoDisconnectInterrupt() to add or remove interrupts from the dispatch list. - Implement KeAcquireInterruptSpinLock() and KeReleaseInterruptSpinLock(). - Change the DPC and workitem threads to use the KeXXXSpinLock API instead of mtx_lock_spin()/mtx_unlock_spin(). - Simplify the NdisXXXPacket routines by creating an actual packet pool structure and using the InterlockedSList routines to manage the packet queue. - Only honor the value returned by OID_GEN_MAXIMUM_SEND_PACKETS for serialized drivers. For deserialized drivers, we now create a packet array of 64 entries. (The Microsoft DDK documentation says that for deserialized miniports, OID_GEN_MAXIMUM_SEND_PACKETS is ignored, and the driver for the Marvell 8335 chip, which is a deserialized miniport, returns 1 when queried.) - Clean up timer handling in subr_ntoskrnl. - Add the following conditional debugging code: NTOSKRNL_DEBUG_TIMERS - add debugging and stats for timers NDIS_DEBUG_PACKETS - add extra sanity checking for NdisXXXPacket API NTOSKRNL_DEBUG_SPINLOCKS - add test for spinning too long - In kern_ndis.c, always start the HAL first and shut it down last, since Windows spinlocks depend on it. Ntoskrnl should similarly be started second and shut down next to last. Notes: svn path=/head/; revision=151451

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First and most importantly, I threw out the thread priority-twiddling implementation of KeRaiseIrql()/KeLowerIrq()/KeGetCurrentIrql() in favor of a new scheme that uses sleep mutexes. The old scheme was really very naughty and sought to provide the same behavior as Windows spinlocks (i.e. blocking pre-emption) but in a way that wouldn't raise the ire of WITNESS. The new scheme represents 'DISPATCH_LEVEL' as the acquisition of a per-cpu sleep mutex. If a thread on cpu0 acquires the 'dispatcher mutex,' it will block any other thread on the same processor that tries to acquire it, in effect only allowing one thread on the processor to be at 'DISPATCH_LEVEL' at any given time. It can then do the 'atomic sit and spin' routine on the spinlock variable itself. If a thread on cpu1 wants to acquire the same spinlock, it acquires the 'dispatcher mutex' for cpu1 and then it too does an atomic sit and spin to try acquiring the spinlock. Unlike real spinlocks, this does not disable pre-emption of all threads on the CPU, but it does put any threads involved with the NDISulator to sleep, which is just as good for our purposes. This means I can now play nice with WITNESS, and I can safely do things like call malloc() when I'm at 'DISPATCH_LEVEL,' which you're allowed to do in Windows. Next, I completely re-wrote most of the event/timer/mutex handling and wait code. KeWaitForSingleObject() and KeWaitForMultipleObjects() have been re-written to use condition variables instead of msleep(). This allows us to use the Windows convention whereby thread A can tell thread B "wake up with a boosted priority." (With msleep(), you instead have thread B saying "when I get woken up, I'll use this priority here," and thread A can't tell it to do otherwise.) The new KeWaitForMultipleObjects() has been better tested and better duplicates the semantics of its Windows counterpart. I also overhauled the IoQueueWorkItem() API and underlying code. Like KeInsertQueueDpc(), IoQueueWorkItem() must insure that the same work item isn't put on the queue twice. ExQueueWorkItem(), which in my implementation is built on top of IoQueueWorkItem(), was also modified to perform a similar test. I renamed the doubly-linked list macros to give them the same names as their Windows counterparts and fixed RemoveListTail() and RemoveListHead() so they properly return the removed item. I also corrected the list handling code in ntoskrnl_dpc_thread() and ntoskrnl_workitem_thread(). I realized that the original logic did not correctly handle the case where a DPC callout tries to queue up another DPC. It works correctly now. I implemented IoConnectInterrupt() and IoDisconnectInterrupt() and modified NdisMRegisterInterrupt() and NdisMDisconnectInterrupt() to use them. I also tried to duplicate the interrupt handling scheme used in Windows. The interrupt handling is now internal to ndis.ko, and the ndis_intr() function has been removed from if_ndis.c. (In the USB case, interrupt handling isn't needed in if_ndis.c anyway.) NdisMSleep() has been rewritten to use a KeWaitForSingleObject() and a KeTimer, which is how it works in Windows. (This is mainly to insure that the NDISulator uses the KeTimer API so I can spot any problems with it that may arise.) KeCancelTimer() has been changed so that it only cancels timers, and does not attempt to cancel a DPC if the timer managed to fire and queue one up before KeCancelTimer() was called. The Windows DDK documentation seems to imply that KeCantelTimer() will also call KeRemoveQueueDpc() if necessary, but it really doesn't. The KeTimer implementation has been rewritten to use the callout API directly instead of timeout()/untimeout(). I still cheat a little in that I have to manage my own small callout timer wheel, but the timer code works more smoothly now. I discovered a race condition using timeout()/untimeout() with periodic timers where untimeout() fails to actually cancel a timer. I don't quite understand where the race is, using callout_init()/callout_reset()/callout_stop() directly seems to fix it. I also discovered and fixed a bug in winx32_wrap.S related to translating _stdcall calls. There are a couple of routines (i.e. the 64-bit arithmetic intrinsics in subr_ntoskrnl) that return 64-bit quantities. On the x86 arch, 64-bit values are returned in the %eax and %edx registers. However, it happens that the ctxsw_utow() routine uses %edx as a scratch register, and x86_stdcall_wrap() and x86_stdcall_call() were only preserving %eax before branching to ctxsw_utow(). This means %edx was getting clobbered in some cases. Curiously, the most noticeable effect of this bug is that the driver for the TI AXC110 chipset would constantly drop and reacquire its link for no apparent reason. Both %eax and %edx are preserved on the stack now. The _fastcall and _regparm wrappers already handled everything correctly. I changed if_ndis to use IoAllocateWorkItem() and IoQueueWorkItem() instead of the NdisScheduleWorkItem() API. This is to avoid possible deadlocks with any drivers that use NdisScheduleWorkItem() themselves. The unicode/ansi conversion handling code has been cleaned up. The internal routines have been moved to subr_ntoskrnl and the RtlXXX routines have been exported so that subr_ndis can call them. This removes the incestuous relationship between the two modules regarding this code and fixes the implementation so that it honors the 'maxlen' fields correctly. (Previously it was possible for NdisUnicodeStringToAnsiString() to possibly clobber memory it didn't own, which was causing many mysterious crashes in the Marvell 8335 driver.) The registry handling code (NdisOpen/Close/ReadConfiguration()) has been fixed to allocate memory for all the parameters it hands out to callers and delete whem when NdisCloseConfiguration() is called. (Previously, it would secretly use a single static buffer.) I also substantially updated if_ndis so that the source can now be built on FreeBSD 7, 6 and 5 without any changes. On FreeBSD 5, only WEP support is enabled. On FreeBSD 6 and 7, WPA-PSK support is enabled. The original WPA code has been updated to fit in more cleanly with the net80211 API, and to eleminate the use of magic numbers. The ndis_80211_setstate() routine now sets a default authmode of OPEN and initializes the RTS threshold and fragmentation threshold. The WPA routines were changed so that the authentication mode is always set first, followed by the cipher. Some drivers depend on the operations being performed in this order. I also added passthrough ioctls that allow application code to directly call the MiniportSetInformation()/MiniportQueryInformation() methods via ndis_set_info() and ndis_get_info(). The ndis_linksts() routine also caches the last 4 events signalled by the driver via NdisMIndicateStatus(), and they can be queried by an application via a separate ioctl. This is done to allow wpa_supplicant to directly program the various crypto and key management options in the driver, allowing things like WPA2 support to work. Whew.

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-102-27/+29
| | | | | | | | | | | | | | | | | | | | | | | struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

* Deal with a few bootstrap issues:Bill Paul2005-05-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can't call KeFlushQueuedDpcs() during bootstrap (cold == 1), since the flush operation sleeps to wait for completion, and we can't sleep here (clowns will eat us). On an i386 SMP system, if we're loaded/probed/attached during bootstrap, smp_rendezvous() won't run us anywhere except CPU 0 (since the other CPUs aren't launched until later), which means we won't be able to set up the GDTs anywhere except CPU 0. To deal with this case, ctxsw_utow() now checks to see if the TID for the current processor has been properly initialized and sets up the GTD for the current CPU if not. Lastly, in if_ndis.c:ndis_shutdown(), do an ndis_stop() to insure we really halt the NIC and stop interrupts from happening. Note that loading a driver during bootstrap is, unfortunately, kind of a hit or miss sort of proposition. In Windows, the expectation is that by the time a given driver's MiniportInitialize() method is called, the system is already in 'multiuser' state, i.e. it's up and running enough to support all the stuff specified in the NDIS API, which includes the underlying OS-supplied facilities it implicitly depends on, such as having all CPUs running, having the DPC queues initialized, WorkItem threads running, etc. But in UNIX, a lot of that stuff won't work during bootstrap. This causes a problem since we need to call MiniportInitialize() at least once during ndis_attach() in order to find out what kind of NIC we have and learn its station address. What this means is that some cards just plain won't work right if you try to pre-load the driver along with the kernel: they'll only be probed/attach correctly if the driver is kldloaded _after_ the system has reached multiuser. I can't really think of a way around this that would still preserve the ability to use an NDIS device for diskless booting. Notes: svn path=/head/; revision=146427

* Add support for NdisMEthIndicateReceive() and MiniportTransferData().Bill Paul2005-05-152-0/+226
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Ralink RT2500 driver uses this API instead of NdisMIndicateReceivePacket(). Drivers use NdisMEthIndicateReceive() when they know they support 802.3 media and expect to hand their packets only protocols that want to deal with that particular media type. With this API, the driver does not manage its own NDIS_PACKET/NDIS_BUFFER structures. Instead, it lets bound protocols have a peek at the data, and then they supply an NDIS_PACKET/NDIS_BUFFER combo to the miniport driver, into which it copies the packet data. Drivers use NdisMIndicateReceivePacket() to allow their packets to be read by any protocol, not just those bound to 802.3 media devices. To make this work, we need an internal pool of NDIS_PACKETS for receives. Currently, we check to see if the driver exports a MiniportTransferData() method in its characteristics structure, and only allocate the pool for drivers that have this method. This should allow the RT2500 driver to work correctly, though I still have to fix ndiscvt(8) to parse its .inf file properly. Also, change kern_ndis.c:ndis_halt_nic() to reap timers before acquiring NDIS_LOCK(), since the reaping process might entail sleeping briefly (and we can't sleep with a lock held).
