Fix wrong asresp frame parsing in iwi_checkforqos().
After 8.0-RELEASE, iwi(4) doesn't send any data frames in infrastructure mode.
Bacause of the condition `while (frm < efrm)', IEEE80211_VERIFY_LENGTH() was checking item length beyond the ieee80211_frame region, and returned from iwi_checkforqos() without setting flags, capinfo and associd.
In infrastructure mode associd is required, so this problem causes discarding mbuf in ieee80211_start().

The firmware does pad notifications to an even number of bytes (at least the association notification), the included information though always contains an elem block with an odd number of bytes. We handle the last byte as if it might contain a whole elem block, this of course is not true as one byte is not enough to hold a block, we therefore discard the complete frame. The solution here is to subtract one from the actual notification length, this is also what the Linux driver does. With this change the frames ends exactly where the last elem block ends.
This commit also reverts r214160 which is no longer required and now even wrong.

Create a taskqueue for each wireless interface which provides a serialised sleepable context for net80211 driver callbacks. This removes the need for USB and firmware based drivers to roll their own code to defer the chip programming for state changes, scan requests, channel changes and mcast/promisc updates. When a driver callback completes the hardware state is now guaranteed to have been updated and is in sync with net80211 layer.
This nukes around 1300 lines of code from the wireless device drivers making them more readable and less race prone.
The net80211 layer has been updated as follows - all state/channel changes are serialised on the taskqueue. - ieee80211_new_state() always queues and can now be called from any context - scanning runs from a single taskq function and executes to completion. driver callbacks are synchronous so the channel, phy mode and rx filters are guaranteed to be set in hardware before probe request frames are transmitted.

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.

Fix an off-by-one error in iwi_init_fw_dma(). It didn't reuse the existing DMA memory for a firmware load if it was the exact size needed, thus in the common case the driver was constantly free'ing and reallocating the DMA buffer and it would eventually begin to fail. With this fix, iwi0 reuses the same buffer the entire time and no longer fails to load the firmware after the machine has been up for a while.

Rename IWI_LOCK_ASSERT to IWI_LOCK_CHECK per Sam's suggestion, and make it print under debug.iwi control same as other debugging stuff.
Remove the device_printf() in iwi_ioctl() and replace with this:
/* * wait until pending iwi_cmd() are completed, to avoid races * that could cause problems. */ while (sc->flags & IWI_FLAG_BUSY) msleep(sc, &sc->sc_mtx, 0, "iwiioctl", hz);
This at least prevents what has become an almost systematic failure for my system, presumably due to a previous iwi_cmd() not complete yet by the time iwi_ioctl() is called.
It has been pointed to my attention that the real problem could be calling ieee80211_ioctl() with the lock held. If that is true, there might still be a possibility for a race condition e.g. an interrupt coming while the ioctl is sleeping. Need to investigate further on what changes are required to release the lock before calling ieee80211_ioctl

Address a few issues with the iwi driver, namely:
+ do not release the dma-ble region used for downloading firmware. This should fix the problems that some people were seeing, due to memory becoming too fragmented which prevented subsequent allocations of a suitable contiguous region of memory;
+ document the firmware format and usage in if_iwivar.h
+ use a loop to allocate the four tx rings, instead of replicating the body of the loop.
+ add debugging code IWI_LOCK_ASSERT() to detect missing locks. These only do a printf, and should go away once we figure out why the driver sometimes freezes the system due to a (yet unidentified) race condition.
+ add a device_printf() in iwi_ioctl() in certain conditions (see comment in the code). This helps preventing the race condition mentioned above, and makes the system survive. This printf will also go away once fixing this bug is completed.
+ change iwi_getfw() to return 0 on success, 1 on error, consistently with other functions.
+ fix the argument of a sizeof() in iwi_get_firmware()
+ use le32toh() to access little-endian fields
+ simplify error handling in iwi_load_firmware() and iwi_init_locked()

Cleanup and document the implementation of firmware(9) based on a version that i posted earlier on the -current mailing list, and subsequent feedback received.
The core of the change is just in sys/firmware.h and kern/subr_firmware.c, while other files are just adaptation of the clients to the ABI change (const-ification of some parameters and hiding of internal info, so this is fully compatible at the binary level).
In detail: - reduce the amount of information exported to clients in struct firmware, and constify the pointer;
- internally, document and simplify the implementation of the various functions, and make sure error conditions are dealt with properly.
The diffs are large, but the code is really straightforward now (i hope).
Note also that there is a subtle issue with the implementation of firmware_register(): currently, as in the previous version, we just store a reference to the 'imagename' argument, but we should rather copy it because there is no guarantee that this is a static string. I realised this while testing this code, but i prefer to fix it in a later commit -- there is no regression with respect to the past.
Note, too, that the version in RELENG_6 has various bugs including missing locks around the module release calls, mishandling of modules loaded by /boot/loader, and so on, so an MFC is absolutely necessary there. I was just postponing it until this cleanup to avoid doing things twice.

add missed calls to bpf_peers_present
|
#

csjp |
Fix the following bpf(4) race condition which can result in a panic:
(1) bpf peer attaches to interface netif0 (2) Packet is received by netif0 (3) ifp->if_bpf pointer is checked and handed off to bpf (4) bpf peer detaches from netif0 resulting in ifp->if_bpf being initialized to NULL. (5) ifp->if_bpf is dereferenced by bpf machinery (6) Kaboom
This race condition likely explains the various different kernel panics reported around sending SIGINT to tcpdump or dhclient processes. But really this race can result in kernel panics anywhere you have frequent bpf attach and detach operations with high packet per second load.
Summary of changes:
- Remove the bpf interface's "driverp" member - When we attach bpf interfaces, we now set the ifp->if_bpf member to the bpf interface structure. Once this is done, ifp->if_bpf should never be NULL. [1] - Introduce bpf_peers_present function, an inline operation which will do a lockless read bpf peer list associated with the interface. It should be noted that the bpf code will pickup the bpf_interface lock before adding or removing bpf peers. This should serialize the access to the bpf descriptor list, removing the race. - Expose the bpf_if structure in bpf.h so that the bpf_peers_present function can use it. This also removes the struct bpf_if; hack that was there. - Adjust all consumers of the raw if_bpf structure to use bpf_peers_present
Now what happens is:
(1) Packet is received by netif0 (2) Check to see if bpf descriptor list is empty (3) Pickup the bpf interface lock (4) Hand packet off to process
From the attach/detach side:
(1) Pickup the bpf interface lock (2) Add/remove from bpf descriptor list
Now that we are storing the bpf interface structure with the ifnet, there is is no need to walk the bpf interface list to locate the correct bpf interface. We now simply look up the interface, and initialize the pointer. This has a nice side effect of changing a bpf interface attach operation from O(N) (where N is the number of bpf interfaces), to O(1).
[1] From now on, we can no longer check ifp->if_bpf to tell us whether or not we have any bpf peers that might be interested in receiving packets.

Be more robust when handling Rx interrupts. If we can't allocate and DMA map a new mbuf, just discard the received frame and reuse the old mbuf. This should fix kernel panics on high network traffic.

Make sure that we call if_free(ifp) after bus_teardown_intr. Since we could get an interrupt after we free the ifp, and the interrupt handler depended on the ifp being still alive, this could, in theory, cause a crash. Eliminate this possibility by moving the if_free to after the bus_teardown_intr() call.

Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags. This helps prevent races between the network stack and device driver in maintaining the interface flags field.
Many __FreeBSD__ and __FreeBSD_version checks maintained and continued; some less so.

Stop embedding struct ifnet at the top of driver softcs. Instead the 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.

This breaks 802.11a support. o Temporarly switch back to software WEP until I implement hardware encryption for AES and TKIP too.
