| | | | | | | | | | | | | IF_ADDR_UNLOCK() across network device drivers when accessing the per-interface multicast address list, if_multiaddrs. This will allow us to change the locking strategy without affecting our driver programming interface or binary interface. For two wireless drivers, remove unnecessary locking, since they don't actually access the multicast address list. Approved by: re (kib) MFC after: 6 weeks

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (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. In collaboration with: sam@ MFC after: 1 month

* Fixing WEP bustage in hostap mode since 5.2-RELEASE.avatar2005-10-022-15/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - WEP TX fix: The original code called software crypto, ieee80211_crypto_encap(), which never worked since IEEE80211_KEY_SWCRYPT was never flagged due to ieee80211_crypto_newkey() assumes that wi always supports hardware based crypto regardless of operational mode(by virtue of IEEE80211_C_WEP). This fix works around that issue by adding wi_key_alloc() to force the use of s/w crypto. Also if anyone ever decides to cleanup ioctl handling where key changes wouldn't cause a call to wi_init() every time, we'll need wi_key_alloc() to DTRT. In addition to that, this fix also adds code to wi_write_wep() to force existing keys to be switched between h/w and s/w crypto such that an operation mode change(sta <-> hostap) will flag IEEE80211_KEY_SWCRYPT properly. - WEP RX fix: Clear IEEE80211_F_DROPUNENC even in hostap mode. Quote from Sam: "This is really gross but I don't see an easy way around it. By doing it we lose the ability to independently drop unencode frames (and support mixed wep/!wep use). We should really be setting the EXCLUDE_UNENCRYPTED flag written in wi_write_wep based on IEEE80211_F_DROPUNENC but with our clearing it we can't depend on it being set properly."
