* Rename definition of IEEE80211_FC1_WEP to IEEE80211_FC1_PROTECTED.Kevin Lo2014-01-081-2/+2
| | | | | | | | | | | | | | The origin of WEP comes from IEEE Std 802.11-1997 where it defines whether the frame body of MAC frame has been encrypted using WEP algorithm or not. IEEE Std. 802.11-2007 changes WEP to Protected Frame, indicates whether the frame is protected by a cryptographic encapsulation algorithm.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Cleanup and document the implementation of firmware(9) based onLuigi Rizzo2007-02-152-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. MFC after: 1 week Notes: svn path=/head/; revision=166756

* Fix the following bpf(4) race condition which can result in a panic:Christian S.J. Peron2006-06-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (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.
