1.9	21-Mar-2013	christos	Don't attempt to dereference ANYC (since it is a pointer to 0x1). Fixes random crashes in hostap mode (race conditions in the interrupt handler while the interface comes up or down).
1.8	10-Jan-2009	cegger	branches: 1.8.14; 1.8.24; Introduce ieee80211_setbasicrates(). Use it to set speed in ieee80211_ifattach(). Export new ieee80211_std_rateset_11{a,b,g}. From OpenBSD.
1.7	28-Jul-2008	christos	branches: 1.7.2; - trailing commas in enums - arithmetic on enums needs cast from Anon Ymous
1.6	16-Dec-2007	degroote	branches: 1.6.4; 1.6.6; 1.6.10; 1.6.12; 1.6.14; 1.6.16; Add support for the command list scan in ifconfig (this command permits to scan access point in the neighbourhood). Complete list of channel attributes and list of management information element payload. While here, use estrlcpy instead of strncpy. From FreeBSD ifconfig and net80211
1.5	08-Mar-2006	lukem	branches: 1.5.36; 1.5.46; 1.5.50; Use the SI capitalization for "Hz", "kHz", and "MHz" in comments and strings. Add a space between numbers and Hz unit.
1.4	02-Mar-2006	dyoung	branches: 1.4.2; 1.4.4; Miscellaneous ath(4) and net80211 updates and bug-fixes coming from sam@ and various open source repositories: ath(4): Ignore "phantom" beacon misses: should stabilize connections to access points (no more ceaseless link-UP/DOWN indications). Also, re-synchronize beacon timer using the TSF in the first beacon received after joining a BSS---this should also help suppress spurious beacon misses. I am hopeful that this will help ath(4) lossage reported by perry@ and smb@. Add new configuration through sysctl. Use a shorter calibration interval until IQ calibration finishes. Report antenna noise through radiotap. Rudiments of Radar Detection / Dynamic Frequency Selection. Update to HAL version 0.9.16.13. Update open sources for changes to the HAL API. Add HALs for additional architectures: add big-endian ELF HALs for sparc64 and for PowerPC. Also add a Alpha HAL. These new HALs are untested under NetBSD. ath(4) + net80211: Make the multicast transmit rate configurable by ioctl. Miscellaneous bug fixes.
1.3	10-Dec-2005	elad	branches: 1.3.4; 1.3.6; Multiple inclusion protection, as suggested by christos@ on tech-kern@ few days ago.
1.2	20-Nov-2005	dyoung	Set the "special" struct ieee80211_channel pointer, IEEE80211_CHAN_ANYC, to 0x1 instead of 0xffff, so the kernel will trap accidental dereferences. I don't set IEEE80211_CHAN_ANYC to NULL because it may have a distinct meaning in net80211. Thanks to Steve Woodford for pointing out that 0xffff may be a valid kernel memory address on x86.

1.3.30.1	12-Jul-2018	phil	State save. New kernel config for this brach only. TESTWIFI does produce a kernel. It is not working. athn files not compiling yet and commented out of the TESTWIFI kernel, which only has urtwn 802.11 driver enabled. ieee80211_alq.c and ieee80211_ddb.c not compiling yet.
1.61	21-Aug-2021	andvar	fix some more typos in comments/log messages, improve wording as well.
1.60	06-Oct-2020	roy	net80211: Initialise the interface with a decent link state. Link state transitions to UP when a node is joined and DOWN when left. This means that with the interface UP, the link state could be UNKNOWN for a while, implying it can be used in BSS mode. Which is of course false. Add a function to set an initial link state based on the operating mode. Also call this when the operating mode changes. Basically in BSS and MONITOR it starts off down. BSS will transition UP and DOWN as before, MONITOR will stay down. IBSS, AHDEMO and HOSTAP will remain as link unknown because the state is ..... unknown.
1.59	15-Mar-2020	thorpej	Define and implement a locking protocol for the ifmedia / mii layers: - MP-safe drivers provide a mutex to ifmedia that is used to serialize access to media-related structures / hardware regsiters. Converted drivers use the new ifmedia_init_with_lock() function for this. The new name is provided to ease the transition. - Un-converted drivers continue to call ifmedia_init(), which will supply a compatibility lock to be used instead. Several media-related entry points must be aware of this compatibility lock, and are able to acquire it recursively a limited number of times, if needed. This is a SPIN mutex with priority IPL_NET. - This same lock is used to serialize access to PHY registers and other MII-related data structures. The PHY drivers are modified to acquire and release the lock, as needed, and assert the lock is held as a diagnostic aid. The "usbnet" framework has had an overhaul of its internal locking protocols to fit in with the media / mii changes, and the drivers adapted. USB wifi drivers have been changed to provide their own adaptive mutex to the ifmedia later via a new ieee80211_media_init_with_lock() function. This is required because the USB drivers need an adaptive mutex. Besised "usbnet", a few other drivers are converted: vmx, wm, ixgbe / ixv. mcx also now calls ifmedia_init_with_lock() because it needs to also use an adaptive mutex. The mcx driver still needs to be fully converted to NET_MPSAFE.
1.58	04-Feb-2020	thorpej	Use ifmedia_fini().

1.54	21-Mar-2013	christos	Instead of always checking for ANYC, make it a valid channel
1.53	05-Apr-2010	joerg	branches: 1.53.8; 1.53.18; Push the bpf_ops usage back into bpf.h. Push the common ifp->if_bpf check into the inline functions as well the fourth argument for bpf_attach.
1.52	02-Apr-2010	dyoung	Delete ieee80211_setbasicrates(). It's buggy, and we drivers can get along fine without it.
1.51	26-Mar-2010	dyoung	In ieee80211_media_init(), change a pointer that we never write through to a pointer to const.
1.50	19-Jan-2010	pooka	branches: 1.50.2; 1.50.4; Redefine bpf linkage through an always present op vector, i.e. #if NBPFILTER is no longer required in the client. This change doesn't yet add support for loading bpf as a module, since drivers can register before bpf is attached. However, callers of bpf can now be modularized. Dynamically loadable bpf could probably be done fairly easily with coordination from the stub driver and the real driver by registering attachments in the stub before the real driver is loaded and doing a handoff. ... and I'm not going to ponder the depths of unload here. Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.
1.49	10-Jan-2009	cegger	Introduce ieee80211_setbasicrates(). Use it to set speed in ieee80211_ifattach(). Export new ieee80211_std_rateset_11{a,b,g}. From OpenBSD.

1.43	13-Dec-2005	dyoung	branches: 1.43.4; 1.43.6; Fix ieee80211_media2rate to suit the funny order of NetBSD's DSSS media flags: DS2, DS5, DS11, DS1.
1.42	25-Nov-2005	thorpej	Use a once control to call initialize the 802.11 layer when ieee80211_ifattach() is called. "wlan" no longer needs-flag, and remove the ieee80211_init() call from main().

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. Reviewed by: pjd, bz MFC after: 7 days 2005-08-08 19:46 sam Split crypto tx+rx key indices and add a key index -> node mapping table: Crypto changes: o change driver/net80211 key_alloc api to return tx+rx key indices; a driver can leave the rx key index set to IEEE80211_KEYIX_NONE or set it to be the same as the tx key index (the former disables use of the key index in building the keyix->node mapping table and is the default setup for naive drivers by null_key_alloc) o add cs_max_keyid to crypto state to specify the max h/w key index a driver will return; this is used to allocate the key index mapping table and to bounds check table loookups o while here introduce ieee80211_keyix (finally) for the type of a h/w key index o change crypto notifiers for rx failures to pass the rx key index up as appropriate (michael failure, replay, etc.) Node table changes: o optionally allocate a h/w key index to node mapping table for the station table using the max key index setting supplied by drivers (note the scan table does not get a map) o defer node table allocation to lateattach so the driver has a chance to set the max key id to size the key index map o while here also defer the aid bitmap allocation o add new ieee80211_find_rxnode_withkey api to find a sta/node entry on frame receive with an optional h/w key index to use in checking mapping table; also updates the map if it does a hash lookup and the found node has a rx key index set in the unicast key; note this work is separated from the old ieee80211_find_rxnode call so drivers do not need to be aware of the new mechanism o move some node table manipulation under the node table lock to close a race on node delete o add ieee80211_node_delucastkey to do the dirty work of deleting unicast key state for a node (deletes any key and handles key map references) Ath driver: o nuke private sc_keyixmap mechansim in favor of net80211 support o update key alloc api These changes close several race conditions for the ath driver operating in ap mode. Other drivers should see no change. Station mode operation for ath no longer uses the key index map but performance tests show no noticeable change and this will be fixed when the scan table is eliminated with the new scanning support.

Previously we allocated a node from the station table, sent the frame (using the node), then released the reference that "held the frame in the table". But while the frame was in flight the node might be reclaimed which could lead to problems. The solution is to add an ieee80211_tmp_node routine that crafts a node that does exist in a table and so isn't ever reclaimed; it exists only so long as the associated frame is in flight.

1.37	22-Jun-2005	dyoung	Resolve conflicts in importation of 18-May-2005 ath(4) / net80211(9) from FreeBSD. Introduce compatibility shims (sys/dev/ic/ath_netbsd.[ch], sys/net80211/ieee80211_netbsd.[ch]). Update drivers (an, atu, atw, awi, ipw, iwi, rtw, wi) for the new net80211(9) API.
1.36	20-Jun-2005	atatat	Change the rest of the sysctl subsystem to use const consistently. The __UNCONST macro is now used only where necessary and the RW macros are gone. Most of the changes here are consumers of the sysctl_createv(9) interface that now takes a pair of const pointers which used not to be.

1.32	10-Aug-2004	dyoung	branches: 1.32.4; 1.32.6; Make the node table into an LRU cache: least-recently used nodes are at the end of the node queue. Change the reference-counting discipline: ni->ni_refcnt indicates how many times net80211 has granted ni to the driver. Every node in the table with ni_refcnt=0 is eligible to be garbage-collected. The mere presence of a node in the table does not any longer indicate its auth/assoc state; nodes have a ni_state variable, now. A sysctl, net.link.ieee80211.maxnodecache, controls the maximum LRU cache size. While I am here, patch ieee80211_find_node_for_beacon to do a "best match" by bssid/ssid/channel, not a "perfect match." This keeps net80211 from caching duplicate nodes in the table.
1.31	30-Jul-2004	mycroft	branches: 1.31.2; Change the basic rate list for 11g to contain just the 11b modes, mimicking the behavior of other systems.
1.30	30-Jul-2004	dyoung	For interoperability with legacy equipment, do not enable short preamble by default.
1.29	30-Jul-2004	dyoung	Change sysctl range-checking: net.link.ieee80211.debug values are now 0x0 -> 0xffffffff, not 0 -> 2.
1.28	23-Jul-2004	mycroft	Cleanup of ieee80211_node from madwifi: * Don't use ifp pointers; use ieee80211com. * Implement the locking macros that are used under FreeBSD and Linux.
1.27	23-Jul-2004	mycroft	Changes from madwifi: Abstract some of the node management code into separate functions, and use them throughout, plugging memory leaks. Allocate the AID allocation map dynamically.
1.26	23-Jul-2004	mycroft	More diff reduction; mainly IEEE80211_DPRINTF() stuff.
1.25	23-Jul-2004	mycroft	Diff reduction vs. madwifi. Change the signature of IEEE80211_DPRINTF() so that it uses a bitmask, and convert some of the if_printf()s to IEEE80211_DPRINTF()s. XXX I'm using a global variable at the moment rather than per-interface.
1.24	23-Jul-2004	mycroft	IEEE80211_MAX_AID has been renamed to IEEE80211_AID_MAX.
1.23	22-Jul-2004	mycroft	The low-level drivers are not setting the "basic rate" bit in the rateset. Instead, change _set11gbasicrate() to _setbasicrates(), have it operate on all modes, and call it from *_ifattach(). Also, fix obvious bugs in it (it had an off-by-one error, at least).

1.13	09-May-2004	dyoung	In ieee80211_find_rxnode, when we "fake up" a node for an ad hoc peer, we have to copy the "master" rate table to the faked-up node's rate table, or else ath0 will complain, "ath0: bogus xmit rate 0x0". Thank you Konstantin KABASSANOV for reporting this problem.
1.12	06-May-2004	dyoung	Following Andrew Brown's suggestion, move net.ieee80211 to net.link.ieee80211. The convention is that nodes directly under net are protocol families (PF_*). Also, simplify the sysctl setup for net80211 and rssadapt, following another suggestion by Andrew.
1.11	06-May-2004	dyoung	Add a sysctl, net.ieee80211.debug, for turning debug messages on and off. Add a sysctl, net.ieee80211.maxinact, for adjusting the node time-out interval. After net.ieee80211.maxinact seconds of inactivity, an AP will purge a peer/client-record. Now the client has to reassociate.
1.10	30-Apr-2004	dyoung	From FreeBSD. Change ieee80211_phymode_name from a subroutine back to an array. Rearrange ieee80211_setmode. Miscellaneous small changes to make our code and FreeBSD's agree.
1.9	13-Jan-2004	dyoung	branches: 1.9.2; NetBSD's KASSERT takes just one argument while FreeBSD's takes two, so I have added IASSERT(cond, complaint) to the compatibility header file and s/KASSERT/IASSERT/'d.

1.5	13-Oct-2003	dyoung	More changes to the new 802.11 layer: * Add Kevin Lahey's power-saving support from the old 802.11 layer * Support for frequency-hopping PHYs * Add support frequency-hopping PHY mode, IFM_IEEE80211_FH * Add channel flags for frequency-hopping * Add mode<->media mappings in for FH PHY in ieee80211_media2rate and ieee80211_rate2media * Stop using IFM_MAKEMODE macro since the mode constants (e.g., IFM_IEEE80211_11A) are pre-shifted in sys/net/if_media.h * Add some PLCP constants.
1.4	23-Sep-2003	dyoung	Put FreeBSDisms in #ifdef __FreeBSD__, and add the equivalent NetBSDisms.

1.2	07-Sep-2003	dyoung	First stab at producing a unified NetBSD/FreeBSD 802.11 layer, striving to keep the diffs short and simple. * Replace FreeBSDisms (e.g. struct arpcom) with conditionally-compiled NetBSDism (struct ethercom). * Add compatibility shims in ieee80211_compat.: provide NetBSD with if_printf, for example. Convert FreeBSD node mutex uses to generic node critical-section protection (ieee80211_node_critsect_begin, _end), replace FreeBSD atomic arithmetic with generic alternative, and implement generics in NetBSD * Provide NetBSD-style 802.11 ioctls * Style nits

1.23	08-May-2018	maxv	branches: 1.23.2; Remove three useless debug messages, remove meaningless XXXs, and remove ieee80211_note_frame (unused).
1.22	10-Apr-2018	maxv	Improve an XXX of mine, and fix one stat.
1.21	19-Jan-2018	maxv	branches: 1.21.2; Style, and make sure that there is a header+trailer included in the packet. The crypto functions can touch the trailer, but they don't check whether it's there in the first place.
1.20	17-Jan-2018	maxv	Style, and fix two pretty bad mistakes in the crypto functions: * They call M_PREPEND, but don't pass the updated pointer back to the caller. * They use memmove on the mbuf data, but they don't ensure that the area they touch is contiguous. This fix is not complete, ieee80211_crypto_encap too needs to pass back the updated pointer. This will be done in another commit.
1.19	16-Jan-2018	maxv	Update the mbuf pointer when m_pullup succeeds, I forgot this in my last revision (I only fixed the UAF in one branch). Meanwhile, style.
1.18	10-Dec-2017	maxv	Fix use-after-free: ieee80211_crypto_decap does a pullup on the mbuf but the updated pointer is not passed back. Looks like it is triggerable remotely.

The solution is to add an ieee80211_tmp_node routine that crafts a node that does exist in a table and so isn't ever reclaimed; it exists only so long as the associated frame is in flight.

1.15	03-Sep-2018	riastradh	Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

Noticed by: Michal Mertl Reviewed by: avatar MFC after: 2 weeks 2005-08-10 17:22 sam Clarify/fix handling of the current channel: o add ic_curchan and use it uniformly for specifying the current channel instead of overloading ic->ic_bss->ni_chan (or in some drivers ic_ibss_chan) o add ieee80211_scanparams structure to encapsulate scanning-related state captured for rx frames o move rx beacon+probe response frame handling into separate routines o change beacon+probe response handling to treat the scan table more like a scan cache--look for an existing entry before adding a new one; this combined with ic_curchan use corrects handling of stations that were previously found at a different channel o move adhoc neighbor discovery by beacon+probe response frames to a new ieee80211_add_neighbor routine Reviewed by: avatar Tested by: avatar, Michal Mertl MFC after: 2 weeks 2005-08-09 11:19 rwatson 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. Reviewed by: pjd, bz MFC after: 7 days 2005-08-08 19:46 sam Split crypto tx+rx key indices and add a key index -> node mapping table: Crypto changes: o change driver/net80211 key_alloc api to return tx+rx key indices; a driver can leave the rx key index set to IEEE80211_KEYIX_NONE or set it to be the same as the tx key index (the former disables use of the key index in building the keyix->node mapping table and is the default setup for naive drivers by null_key_alloc) o add cs_max_keyid to crypto state to specify the max h/w key index a driver will return; this is used to allocate the key index mapping table and to bounds check table loookups o while here introduce ieee80211_keyix (finally) for the type of a h/w key index o change crypto notifiers for rx failures to pass the rx key index up as appropriate (michael failure, replay, etc.) Node table changes: o optionally allocate a h/w key index to node mapping table for the station table using the max key index setting supplied by drivers (note the scan table does not get a map) o defer node table allocation to lateattach so the driver has a chance to set the max key id to size the key index map o while here also defer the aid bitmap allocation o add new ieee80211_find_rxnode_withkey api to find a sta/node entry on frame receive with an optional h/w key index to use in checking mapping table; also updates the map if it does a hash lookup and the found node has a rx key index set in the unicast key; note this work is separated from the old ieee80211_find_rxnode call so drivers do not need to be aware of the new mechanism o move some node table manipulation under the node table lock to close a race on node delete o add ieee80211_node_delucastkey to do the dirty work of deleting unicast key state for a node (deletes any key and handles key map references) Ath driver: o nuke private sc_keyixmap mechansim in favor of net80211 support o update key alloc api These changes close several race conditions for the ath driver operating in ap mode. Other drivers should see no change. Station mode operation for ath no longer uses the key index map but performance tests show no noticeable change and this will be fixed when the scan table is eliminated with the new scanning support.

Previously we allocated a node from the station table, sent the frame (using the node), then released the reference that "held the frame in the table". But while the frame was in flight the node might be reclaimed which could lead to problems. The solution is to add an ieee80211_tmp_node routine that crafts a node that does exist in a table and so isn't ever reclaimed; it exists only so long as the associated frame is in flight.

1.109	17-Jan-2018	maxv	Several changes: * Style in several places, to make the code more readable or easier to understand. * Instead of checking m->m_pkthdr.len, check m->m_len. m_pkthdr.len is the total size of the packet, not the size of the current mbuf (which may be smaller). * Add a missing length check when handling QoS frames. * Cast the lengths passed in IEEE80211_VERIFY_LENGTH to size_t. * Remove the length check on scan.sp_xrates, that I added yesterday. xrates gets silently truncated in ieee80211_setup_rates(). * Fix several buffer overflows in the parsers of the MANAGEMENT frames.
1.108	16-Jan-2018	maxv	Various fixes: style, remove tiring XXXs, and prevent integer overflow in ieee80211_setup_rates (normally it already can't happen, because I added a length check on xrates in ieee80211_recv_mgmt_beacon).
1.107	16-Jan-2018	maxv	Prepend 'sp_' to the name of the fields, so that they can easily be found via NXR or grep.

1.96	16-Jan-2018	maxv	Fix overflow.
1.95	16-Jan-2018	maxv	Fix memory leak. If m1 == m, m = NULL, so it's safe to just call m_freem.
1.94	16-Jan-2018	maxv	Style, remove pointless XXXs, and add a comment about LLC.
1.93	16-Jan-2018	maxv	Split ieee80211_input into three sub-functions, that parse received packets depending on their type: DATA -> ieee80211_input_data MANAGEMENT -> ieee80211_input_management CONTROL -> ieee80211_input_control No real functional change, but makes the code much clearer.
1.92	16-Jan-2018	maxv	Start cleaning up this mess.
1.91	10-Dec-2017	maxv	Fix use-after-free: ieee80211_crypto_decap does a pullup on the mbuf but the updated pointer is not passed back. Looks like it is triggerable remotely.
1.90	10-Dec-2017	maxv	Update the pointer after m_pullup, otherwise possible use-after-free.

1.80	09-Feb-2016	ozaki-r	Introduce softint-based if_input This change intends to run the whole network stack in softint context (or normal LWP), not hardware interrupt context. Note that the work is still incomplete by this change; to that end, we also have to softint-ify if_link_state_change (and bpf) which can still run in hardware interrupt. This change softint-ifies at ifp->if_input that is called from each device driver (and ieee80211_input) to ensure Layer 2 runs in softint (e.g., ether_input and bridge_input). To this end, we provide a framework (called percpuq) that utlizes softint(9) and percpu ifqueues. With this patch, rxintr of most drivers just queues received packets and schedules a softint, and the softint dequeues packets and does rest packet processing. To minimize changes to each driver, percpuq is allocated in struct ifnet for now and that is initialized by default (in if_attach). We probably have to move percpuq to softc of each driver, but it's future work. At this point, only wm(4) has percpuq in its softc as a reference implementation. Additional information including performance numbers can be found in the thread at tech-kern@ and tech-net@: http://mail-index.netbsd.org/tech-kern/2016/01/14/msg019997.html Acknowledgment: riastradh@ greatly helped this work.

This change doesn't yet add support for loading bpf as a module, since drivers can register before bpf is attached. However, callers of bpf can now be modularized. Dynamically loadable bpf could probably be done fairly easily with coordination from the stub driver and the real driver by registering attachments in the stub before the real driver is loaded and doing a handoff. ... and I'm not going to ponder the depths of unload here. Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

1.57	02-Mar-2006	dyoung	branches: 1.57.2; 1.57.4; 1.57.6; Miscellaneous ath(4) and net80211 updates and bug-fixes coming from sam@ and various open source repositories: ath(4): Ignore "phantom" beacon misses: should stabilize connections to access points (no more ceaseless link-UP/DOWN indications). Also, re-synchronize beacon timer using the TSF in the first beacon received after joining a BSS---this should also help suppress spurious beacon misses. I am hopeful that this will help ath(4) lossage reported by perry@ and smb@. Add new configuration through sysctl. Use a shorter calibration interval until IQ calibration finishes. Report antenna noise through radiotap. Rudiments of Radar Detection / Dynamic Frequency Selection. Update to HAL version 0.9.16.13. Update open sources for changes to the HAL API. Add HALs for additional architectures: add big-endian ELF HALs for sparc64 and for PowerPC. Also add a Alpha HAL. These new HALs are untested under NetBSD. ath(4) + net80211: Make the multicast transmit rate configurable by ioctl. Miscellaneous bug fixes.

1.53	08-Dec-2005	dyoung	Cosmetic: remove unnecessary stairstep.
1.52	08-Dec-2005	dyoung	Always record a change of the BSS node's BSSID, even if a desired BSSID is set. In IBSS mode, if the BSS node's BSSID changes, and a desired BSSID is not set, make a RUN->RUN transition to give the driver an opportunity to reprogram its BSSID filter. This fixes a bug where both wlanctl(8) and ifconfig(8) indicated that an interface had joined a new BSS, but no packets would get through, except in promiscuous mode, because the hardware still filtered packets based on the old BSSID.
1.51	23-Nov-2005	dyoung	In adhoc mode, mark the "BSS" node's (ic->ic_bss) change of BSSID. If the operator did not configure a "desired BSSID," then we simply adopt the BSS node's new BSSID. If the operator configured a "desired BSSID," the new BSSID is (probably) not the desired one, so start scanning for it. Note that a change of BSSID will occur as two ad hoc networks merge.
1.50	20-Nov-2005	dyoung	Repair adhoc mode. 1 Complete initialization of "faked up" ieee80211_nodes, whose capabilities and other fields are wrong, when we first receive a beacon or probe response from the corresponding neighbor. This entails factoring ieee80211_init_neighbor out of ieee80211_add_neighbor. 2 In adhoc mode, ic->ic_bss is present in the neighbors table, ic->ic_sta, and it is not necessarily the wrong node on which to mark statistics for a rx'd packet. Do not reject ic->ic_bss and fake-up a new node without comparing its MAC address with the address of the sender in the rx'd packet. This fixes a memory leak.
1.49	19-Nov-2005	he	Add an overlooked #if NBPFILTER > 0 / #endif.
1.48	19-Nov-2005	riz	Move the (ALTQ-conditional) declaration of struct altq_pktattr pktattr into ieee80211_deliver_data(), since the code which uses it has been moved there. Fixes build with options ALTQ. reviewed by christos@

Previously we allocated a node from the station table, sent the frame (using the node), then released the reference that "held the frame in the table". But while the frame was in flight the node might be reclaimed which could lead to problems. The solution is to add an ieee80211_tmp_node routine that crafts a node that does exist in a table and so isn't ever reclaimed; it exists only so long as the associated frame is in flight.

1.45	18-Aug-2005	yamt	- introduce M_MOVE_PKTHDR and use it where appropriate. intended to be mostly API compatible with openbsd/freebsd. - remove a glue #define in netipsec/ipsec_osdep.h.
1.44	26-Jul-2005	dyoung	Import changes in FreeBSD's net80211 between 2005-05-18 and 2005-07-11. A summary of changes is forthcoming.
1.43	03-Jul-2005	dyoung	branches: 1.43.2; Restore ALTQ-classification to the AP-bridge, as pointed out by Bernd Ernesti.
1.42	03-Jul-2005	dyoung	Refine an ieee80211_node-match using the SSID and the channel before increasing the _node's beacon/probe count.
1.41	26-Jun-2005	dyoung	Do not build AP support if 'options IEEE80211_NO_HOSTAP'. I will use this in the INSTALL kernel to save some space.
1.40	22-Jun-2005	dyoung	Resolve conflicts in importation of 18-May-2005 ath(4) / net80211(9) from FreeBSD. Introduce compatibility shims (sys/dev/ic/ath_netbsd.[ch], sys/net80211/ieee80211_netbsd.[ch]). Update drivers (an, atu, atw, awi, ipw, iwi, rtw, wi) for the new net80211(9) API.
1.39	30-May-2005	christos	avoid shadowing of m1
1.38	26-Feb-2005	perry	nuke trailing whitespace
1.37	16-Jan-2005	dyoung	branches: 1.37.2; 1.37.4; Fix a misuse of ether_sprintf so that IBSS merges are printed xx:xx:xx:xx:xx:xx -> yy:yy:yy:yy:yy:yy instead of xx:xx:xx:xx:xx:xx -> xx:xx:xx:xx:xx:xx.
1.36	04-Jan-2005	dyoung	IBSS-merge clean-up, inspired by some Linux patches from Jon Anderson (mail@janderson.ca): remove ieee80211_ibss_merge's TSFT argument. Do the TSFT comparison in the drivers (ath, atw). Remove a lot of extraneous debug statements from ieee80211_ibss_merge. Set the ieee80211_node's state to IEEE80211_STA_BSS after it's been copied to the ic_bss, not before. In struct ieee80211_node, make the ni_tstamp field a union of a uint64_t and the 8 TSF octets so that it's easier to compare a neighbor's TSF with the local TSF. Log IBSS merges (Greg Troxel's suggestion). Also log IBSS creation. These are rare and important events that deserve to be logged.
1.35	10-Aug-2004	dyoung	Make the node table into an LRU cache: least-recently used nodes are at the end of the node queue. Change the reference-counting discipline: ni->ni_refcnt indicates how many times net80211 has granted ni to the driver. Every node in the table with ni_refcnt=0 is eligible to be garbage-collected. The mere presence of a node in the table does not any longer indicate its auth/assoc state; nodes have a ni_state variable, now. A sysctl, net.link.ieee80211.maxnodecache, controls the maximum LRU cache size. While I am here, patch ieee80211_find_node_for_beacon to do a "best match" by bssid/ssid/channel, not a "perfect match." This keeps net80211 from caching duplicate nodes in the table.
1.34	30-Jul-2004	mycroft	branches: 1.34.2; Put a check for an impossible case inside '#ifdef DIAGNOSTIC'.
1.33	29-Jul-2004	mycroft	Implement passive scanning for APs in station and host-AP mode: ieee80211_input(): * Do not discard management frames in station mode just because they have the wrong BSSID. * Do not discard beacons in station and host-AP mode when not scanning. * Some minor rearrangement. Update node statistics even if the packet is rejected. ieee80211_recv_mgmt(): * Accept probe responses and beacons in station and host-AP even when not scanning. * Do not immediately free the node created by a beacon or probe response. XXX Should I check BSSIDs more carefully in ieee80211_recv_mgmt() -- specifically for ASSOC_RESP, REASSOC_RESP, AUTH, DEAUTH and DISASSOC? Fix a problem with APs that advertise multiple SSIDs: Change the footprint of ieee80211_find_node_with_channel() to take a SSID as well, and, if not empty, compared it with the existing nodes. This causes us to allocate multiple nodes for the same AP. Without this we were only leaving one SSID in the node table, which might not be the desired one, and so the interface would fail to fully initialize. (Reported by he@ with a Cisco 350 AP.)
1.32	28-Jul-2004	dyoung	Vastly simplify ieee80211_ibss_merge, eliminating the needless callbacks. Change the reference IBSS-merge implementation in atw to match.
1.31	24-Jul-2004	dyoung	Pull the IBSS merge logic out of atw and into net80211, since ath will eventually share it. In the IBSS merge logic, check conditions in a different order so that they run faster in the common case---no merge. Fix the rate-limiting on the debug outputs (enabled by IFF_LINK0).
1.30	23-Jul-2004	mycroft	Cleanup of ieee80211_node from madwifi: * Don't use ifp pointers; use ieee80211com. * Implement the locking macros that are used under FreeBSD and Linux.
1.29	23-Jul-2004	mycroft	Changes from madwifi: Abstract some of the node management code into separate functions, and use them throughout, plugging memory leaks. Allocate the AID allocation map dynamically.
1.28	23-Jul-2004	mycroft	IEEE80211_F_WEPON -> IEEE80211_F_PRIVACY
1.27	23-Jul-2004	mycroft	Yet more DPRINTF() cleanup.
1.26	23-Jul-2004	mycroft	More diff reduction; mainly IEEE80211_DPRINTF() stuff.
1.25	23-Jul-2004	mycroft	Diff reduction vs. madwifi. Change the signature of IEEE80211_DPRINTF() so that it uses a bitmask, and convert some of the if_printf()s to IEEE80211_DPRINTF()s. XXX I'm using a global variable at the moment rather than per-interface.
1.24	31-May-2004	dyoung	Prevent ad hoc lossage: copy the SSID from a beacon into the beacon-sender's ieee80211_node, if ni->ni_esslen == 0. This fixes WEP for Matthew. I think that it also will save us from IBSS splits. Thanks again, Matthew Gream.
1.23	06-May-2004	dyoung	Incorporate new authentication debug statements from FreeBSD. Fix authentication where I had botched it with the FreeBSD import. (In FreeBSD, net80211 is strangely subroutine-averse, so where we have ieee80211_auth_open and ieee80211_auth_shared, they incorporate all of ieee80211_auth_open into ieee80211_recv_mgmt. I had not realized that was why the 20 lines of new code.)
1.22	30-Apr-2004	dyoung	From FreeBSD. Be more consistent with ieee80211_node reference counts, and treat ad hoc nodes properly. More complete authentication support.
1.21	11-Feb-2004	mrg	branches: 1.21.2; fix int/size_t issues in debug code.
1.20	01-Feb-2004	dyoung	This patch from Sam Leffler fixes bugs in the client-side of shared-key authentication. This should help with your Apple products. Any bugs, new or old, are mine.
1.19	15-Jan-2004	onoe	For FH phy, accept beacons whose hop pattern in FH params is different from current setting, because the rssi value would be correct once the datagram is received regardless the hopping pattern.
1.18	14-Jan-2004	dyoung	Don't panic on frames without a second address field. Tap them for BPF, instead.
1.17	13-Jan-2004	dyoung	NetBSD's KASSERT takes just one argument while FreeBSD's takes two, so I have added IASSERT(cond, complaint) to the compatibility header file and s/KASSERT/IASSERT/'d.
1.16	14-Dec-2003	dyoung	Synchronize with FreeBSD sources from 12 Dec 2003.
1.15	07-Dec-2003	dyoung	Diagnostics: complain if packet decapsulation fails.
1.14	27-Oct-2003	mycroft	Eliminate bogus initializer.
1.13	25-Oct-2003	christos	Fix uninitialized variable warning
1.12	25-Oct-2003	mycroft	Do that replacement in one more place.
1.11	25-Oct-2003	mycroft	Replace a constant with a symbol.
1.10	23-Oct-2003	dyoung	In the input path, do not discard management frames belonging to a different BSS, because that keeps drivers like atw from detecting ad hoc beacons with the same SSID but different BSSID for the purpose of IBSS merges. This should be revisited: maybe drivers should check for beacons before handing packets up with ieee80211_input(). However, this restores the atw(4) to working like it did with the old 802.11 layer, and it is nice to re-use the 802.11 layer's packet-decode & -dispatch code (i.e., the ic_recv_mgmt callback).
1.9	18-Oct-2003	itojun	print "association failed" message only if IFF_DEBUG
1.8	18-Oct-2003	onoe	Do not update SSID by beacon, because hidden SSID implementation is vary. ex. 0-length, single space, 0x00 with correct length. So, we don't update SSID in node table by beacon, but always update by Probe Response.
1.7	15-Oct-2003	dyoung	Add WEP shared-key authentication.
1.6	14-Oct-2003	dyoung	Add missing pktattr declaration. Should compile w/ ALTQ, now.
1.5	13-Oct-2003	dyoung	Add Kevin Lahey's power-saving support from the old 802.11 layer Spelling fix: s/unmatch/mismatch/g
1.4	28-Sep-2003	dyoung	More NetBSD-FreeBSD compatibility changes in the pattern #ifdef __FreeBSD__ /* FreeBSDism / #else / NetBSDism */ #endif An important and non-obvious change is in ieee80211_mgmt_output, #ifdef __FreeBSD__ KASSERT(m->m_pkthdr.rcvif == NULL, ("rcvif not null")); #endif Because NetBSD mbufs are not bzero'd like FreeBSD's, we cannot count on rcvif == NULL.
1.3	14-Sep-2003	dyoung	Insert RCSIDs.
1.2	07-Sep-2003	dyoung	First stab at producing a unified NetBSD/FreeBSD 802.11 layer, striving to keep the diffs short and simple. * Replace FreeBSDisms (e.g. struct arpcom) with conditionally-compiled NetBSDism (struct ethercom). * Add compatibility shims in ieee80211_compat.: provide NetBSD with if_printf, for example. Convert FreeBSD node mutex uses to generic node critical-section protection (ieee80211_node_critsect_begin, _end), replace FreeBSD atomic arithmetic with generic alternative, and implement generics in NetBSD * Provide NetBSD-style 802.11 ioctls * Style nits

1.50	07-Nov-2008	dyoung	* Summary * When a link-layer address changes (e.g., ifconfig ex0 link 02:de:ad:be:ef:02 active), send a gratuitous ARP and/or a Neighbor Advertisement to update the network-/link-layer address bindings on our LAN peers. Refuse a change of ethernet address to the address 00:00:00:00:00:00 or to any multicast/broadcast address. (Thanks matt@.) Reorder ifnet ioctl operations so that driver ioctls may inherit the functions of their "class"---ether_ioctl(), fddi_ioctl(), et cetera---and the class ioctls may inherit from the generic ioctl, ifioctl_common(), but both driver- and class-ioctls may override the generic behavior. Make network drivers share more code. Distinguish a "factory" link-layer address from others for the purposes of both protecting that address from deletion and computing EUI64. Return consistent, appropriate error codes from network drivers. Improve readability. KNF. * Details * In if_attach(), always initialize the interface ioctl routine, ifnet->if_ioctl, if the driver has not already initialized it. Delete if_ioctl == NULL tests everywhere else, because it cannot happen. In the ioctl routines of network interfaces, inherit common ioctl behaviors by calling either ifioctl_common() or whichever ioctl routine is appropriate for the class of interface---e.g., ether_ioctl() for ethernets. Stop (ab)using SIOCSIFADDR and start to use SIOCINITIFADDR. In the user->kernel interface, SIOCSIFADDR's argument was an ifreq, but on the protocol->ifnet interface, SIOCSIFADDR's argument was an ifaddr. That was confusing, and it would work against me as I make it possible for a network interface to overload most ioctls. On the protocol->ifnet interface, replace SIOCSIFADDR with SIOCINITIFADDR. In ifioctl(), return EPERM if userland tries to invoke SIOCINITIFADDR. In ifioctl(), give the interface the first shot at handling most interface ioctls, and give the protocol the second shot, instead of the other way around. Finally, let compatibility code (COMPAT_OSOCK) take a shot. Pull device initialization out of switch statements under SIOCINITIFADDR. For example, pull ..._init() out of any switch statement that looks like this: switch (...->sa_family) { case ...: ..._init(); ... break; ... default: ..._init(); ... break; } Rewrite many if-else clauses that handle all permutations of IFF_UP and IFF_RUNNING to use a switch statement, switch (x & (IFF_UP\|IFF_RUNNING)) { case 0: ... break; case IFF_RUNNING: ... break; case IFF_UP: ... break; case IFF_UP\|IFF_RUNNING: ... break; } unifdef lots of code containing #ifdef FreeBSD, #ifdef NetBSD, and #ifdef SIOCSIFMTU, especially in fwip(4) and in ndis(4). In ipw(4), remove an if_set_sadl() call that is out of place. In nfe(4), reuse the jumbo MTU logic in ether_ioctl(). Let ethernets register a callback for setting h/w state such as promiscuous mode and the multicast filter in accord with a change in the if_flags: ether_set_ifflags_cb() registers a callback that returns ENETRESET if the caller should reset the ethernet by calling if_init(), 0 on success, != 0 on failure. Pull common code from ex(4), gem(4), nfe(4), sip(4), tlp(4), vge(4) into ether_ioctl(), and register if_flags callbacks for those drivers. Return ENOTTY instead of EINVAL for inappropriate ioctls. In zyd(4), use ENXIO instead of ENOTTY to indicate that the device is not any longer attached. Add to if_set_sadl() a boolean 'factory' argument that indicates whether a link-layer address was assigned by the factory or some other source. In a comment, recommend using the factory address for generating an EUI64, and update in6_get_hw_ifid() to prefer a factory address to any other link-layer address. Add a routing message, RTM_LLINFO_UPD, that tells protocols to update the binding of network-layer addresses to link-layer addresses. Implement this message in IPv4 and IPv6 by sending a gratuitous ARP or a neighbor advertisement, respectively. Generate RTM_LLINFO_UPD messages on a change of an interface's link-layer address. In ether_ioctl(), do not let SIOCALIFADDR set a link-layer address that is broadcast/multicast or equal to 00:00:00:00:00:00. Make ether_ioctl() call ifioctl_common() to handle ioctls that it does not understand. In gif(4), initialize if_softc and use it, instead of assuming that the gif_softc and ifp overlap. Let ifioctl_common() handle SIOCGIFADDR. Sprinkle rtcache_invariants(), which checks on DIAGNOSTIC kernels that certain invariants on a struct route are satisfied. In agr(4), rewrite agr_ioctl_filter() to be a bit more explicit about the ioctls that we do not allow on an agr(4) member interface. bzero -> memset. Delete unnecessary casts to void . Use sockaddr_in_init() and sockaddr_in6_init(). Compare pointers with NULL instead of "testing truth". Replace some instances of (type )0 with NULL. Change some K&R prototypes to ANSI C, and join lines.

1.24	27-Jul-2005	dyoung	IEEE80211_IOC_BEACON_INTERVAL is not duplicated by SIOC[SG]80211POWER, as I thought. The latter actually sets the station listen interval. We cannot get/set "drop-unencrypted" and "privacy" properties independently with SIOCS80211NWKEY, so put back IEEE80211_IOC_PRIVACY and IEEE80211_IOC_DROPUNENCRYPTED. Thanks Sam Leffler for pointing out my mistakes.
1.23	27-Jul-2005	dyoung	NetBSD already has ioctls that get/set these parameters. Only compile support for the duplicate ioctls from FreeBSD if it is a COMPAT_FREEBSD kernel: IEEE80211_IOC_SSID IEEE80211_IOC_WEPTXKEY IEEE80211_IOC_CHANNEL IEEE80211_IOC_PRIVACY IEEE80211_IOC_DROPUNENCRYPTED IEEE80211_IOC_BSSID IEEE80211_IOC_BEACON_INTERVAL IEEE80211_IOC_WEPKEY
1.22	27-Jul-2005	dyoung	Restore ABI compatibility with SIOCG80211STATS, SIOCG80211ZSTATS in NetBSD 2.0: * If 2.x compatibility is enabled (#ifdef COMPAT_20), compile support for OSIOCG80211STATS and OSIOCG80211ZSTATS, with the same ioctl numbers as SIOCG80211STATS and SIOCG80211ZSTATS in 2.x. OSIOCG80211STATS and OSIOCG80211ZSTATS return an ieee80211_ostats struct, which has the same layout as ieee80211_stats in 2.x. * Add new ioctl numbers for SIOCG80211STATS and SIOCG80211ZSTATS. Both these ioctls will copy at most ifr_buflen bytes of the new ieee80211_stats to ifr_buf.

1.2	07-Sep-2003	dyoung	First stab at producing a unified NetBSD/FreeBSD 802.11 layer, striving to keep the diffs short and simple. * Replace FreeBSDisms (e.g. struct arpcom) with conditionally-compiled NetBSDism (struct ethercom). * Add compatibility shims in ieee80211_compat.: provide NetBSD with if_printf, for example. Convert FreeBSD node mutex uses to generic node critical-section protection (ieee80211_node_critsect_begin, _end), replace FreeBSD atomic arithmetic with generic alternative, and implement generics in NetBSD * Provide NetBSD-style 802.11 ioctls * Style nits

IP traffic doesn't flow yet, not sure where the error is. Added back more NetBSD ioctls not in the FreeBSD code. Still have more to go. Updated my TESTWIFI kernel config.
1.60.18.5	28-Jul-2018	phil	End of the week state save: Got workqueues doing FreeBSD tasks. (still questions on how correct it is.) Incremental changes in many places. Still lots of debugging code that needs to go away some day. "ifconfig urtwn0 up" now does not crash, still needs scan to work properly.

1.60.16.8	22-Jan-2019	pgoyette	Convert the MODULE_{,VOID_}HOOK_CALL macros to do everything in-line rather than defining an intermediate hook##call function. Almost all of the hooks are called only once, and although we lose the ability of doing things like if (MODULE_HOOK_CALL(...) == 0) ... we simplify things quite a bit. With this change, we no longer need to have both declaration and definition macros, and the definition no longer needs to have both prototype argument list and a "real" argument list. FWIW, the above if now needs to written as int ret; MODULE_HOOK_CALL(..., ret); if (ret == 0) ... with appropriate use of braces {}.
1.60.16.7	18-Jan-2019	pgoyette	Don't restrict hooks to having only int or void types. Pass the hook's type to the various macros, as needed. Allows us to reduce diffs to original in at least one or two places (we no longer have to provide an additional parameter to the hook routine for returning a non-int return value).
1.60.16.6	14-Jan-2019	pgoyette	Create a variant of the HOOK macros that handles hook routines of type void, and use them where appropriate.
1.60.16.5	13-Jan-2019	pgoyette	Remove the HOOK2 versions of the MODULE_HOOK macros. There were only a few uses, and using them led to some lack of clarity in the code. Instead, we now use two separate hooks, with names that make it clear(er) what we're doing. This also positions us to start unraveling some of the rtsock_50 mess, which will need (at least) five hooks.
1.60.16.4	29-Sep-2018	pgoyette	In MODULE_HOOK_CALL_DECL we don't need to provide the actual argument list for calling the hook function, nor do we need to provide the default value (for when the hook has not been set).

Previously we allocated a node from the station table, sent the frame (using the node), then released the reference that "held the frame in the table". But while the frame was in flight the node might be reclaimed which could lead to problems. The solution is to add an ieee80211_tmp_node routine that crafts a node that does exist in a table and so isn't ever reclaimed; it exists only so long as the associated frame is in flight.

1.14	27-Jul-2005	dyoung	branches: 1.14.6; We don't really have FreeBSD 802.11 compatibility, and it will take more work to get it right, so change the misleading COMPAT_FREEBSD #ifdefs to #ifdef __FreeBSD__.
1.13	27-Jul-2005	dyoung	IEEE80211_IOC_BEACON_INTERVAL is not duplicated by SIOC[SG]80211POWER, as I thought. The latter actually sets the station listen interval. We cannot get/set "drop-unencrypted" and "privacy" properties independently with SIOCS80211NWKEY, so put back IEEE80211_IOC_PRIVACY and IEEE80211_IOC_DROPUNENCRYPTED. Thanks Sam Leffler for pointing out my mistakes.
1.12	27-Jul-2005	dyoung	NetBSD already has ioctls that get/set these parameters.

OSIOCG80211STATS and OSIOCG80211ZSTATS return an ieee80211_ostats struct, which has the same layout as ieee80211_stats in 2.x. * Add new ioctl numbers for SIOCG80211STATS and SIOCG80211ZSTATS. Both these ioctls will copy at most ifr_buflen bytes of the new ieee80211_stats to ifr_buf.

1.32	03-Sep-2018	riastradh	Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

(mostly passing the address of a uint64_t when typed as CTLTYPE_INT). I've test built quite a few kernels, but there may be some unfixed MD fallout. Most likely passing &char[] to char . Also add CTLFLAG_UNSIGNED for unsiged decimals - not set yet.
1.20	19-Nov-2011	tls	First step of random number subsystem rework described in <20111022023242.BA26F14A158@mail.netbsd.org>. This change includes the following: An initial cleanup and minor reorganization of the entropy pool code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are fixed. Some effort is made to accumulate entropy more quickly at boot time. A generic interface, "rndsink", is added, for stream generators to request that they be re-keyed with good quality entropy from the pool as soon as it is available. The arc4random()/arc4randbytes() implementation in libkern is adjusted to use the rndsink interface for rekeying, which helps address the problem of low-quality keys at boot time. An implementation of the FIPS 140-2 statistical tests for random number generator quality is provided (libkern/rngtest.c). This is based on Greg Rose's implementation from Qualcomm. A new random stream generator, nist_ctr_drbg, is provided. It is based on an implementation of the NIST SP800-90 CTR_DRBG by Henric Jungheim. This generator users AES in a modified counter mode to generate a backtracking-resistant random stream. An abstraction layer, "cprng", is provided for in-kernel consumers of randomness. The arc4random/arc4randbytes API is deprecated for in-kernel use. It is replaced by "cprng_strong". The current cprng_fast implementation wraps the existing arc4random implementation. The current cprng_strong implementation wraps the new CTR_DRBG implementation. Both interfaces are rekeyed from the entropy pool automatically at intervals justifiable from best current cryptographic practice. In some quick tests, cprng_fast() is about the same speed as the old arc4randbytes(), and cprng_strong() is about 20% faster than rnd_extract_data(). Performance is expected to improve. The AES code in src/crypto/rijndael is no longer an optional kernel component, as it is required by cprng_strong, which is not an optional kernel component. The entropy pool output is subjected to the rngtest tests at startup time; if it fails, the system will reboot. There is approximately a 3/10000 chance of a false positive from these tests. Entropy pool _input_ from hardware random numbers is subjected to the rngtest tests at attach time, as well as the FIPS continuous-output test, to detect bad or stuck hardware RNGs; if any are detected, they are detached, but the system continues to run. A problem with rndctl(8) is fixed -- datastructures with pointers in arrays are no longer passed to userspace (this was not a security problem, but rather a major issue for compat32). A new kernel will require a new rndctl. The sysctl kern.arandom() and kern.urandom() nodes are hooked up to the new generators, but the /dev/*random pseudodevices are not, yet. Manual pages for the new kernel interfaces are forthcoming.
1.19	07-Oct-2011	dyoung	branches: 1.19.2; Use atomic_ops(3) to increase/decrease node reference counts, just like the upstream code did, because the current reference counting is potentially racy. This works fine in light testing.

1.23	15-Mar-2020	thorpej	Define and implement a locking protocol for the ifmedia / mii layers: - MP-safe drivers provide a mutex to ifmedia that is used to serialize access to media-related structures / hardware regsiters. Converted drivers use the new ifmedia_init_with_lock() function for this. The new name is provided to ease the transition. - Un-converted drivers continue to call ifmedia_init(), which will supply a compatibility lock to be used instead. Several media-related entry points must be aware of this compatibility lock, and are able to acquire it recursively a limited number of times, if needed. This is a SPIN mutex with priority IPL_NET. - This same lock is used to serialize access to PHY registers and other MII-related data structures. The PHY drivers are modified to acquire and release the lock, as needed, and assert the lock is held as a diagnostic aid. The "usbnet" framework has had an overhaul of its internal locking protocols to fit in with the media / mii changes, and the drivers adapted. USB wifi drivers have been changed to provide their own adaptive mutex to the ifmedia later via a new ieee80211_media_init_with_lock() function. This is required because the USB drivers need an adaptive mutex. Besised "usbnet", a few other drivers are converted: vmx, wm, ixgbe / ixv. mcx also now calls ifmedia_init_with_lock() because it needs to also use an adaptive mutex. The mcx driver still needs to be fully converted to NET_MPSAFE.

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. Reviewed by: pjd, bz MFC after: 7 days 2005-08-08 19:46 sam Split crypto tx+rx key indices and add a key index -> node mapping table: Crypto changes: o change driver/net80211 key_alloc api to return tx+rx key indices; a driver can leave the rx key index set to IEEE80211_KEYIX_NONE or set it to be the same as the tx key index (the former disables use of the key index in building the keyix->node mapping table and is the default setup for naive drivers by null_key_alloc) o add cs_max_keyid to crypto state to specify the max h/w key index a driver will return; this is used to allocate the key index mapping table and to bounds check table loookups o while here introduce ieee80211_keyix (finally) for the type of a h/w key index o change crypto notifiers for rx failures to pass the rx key index up as appropriate (michael failure, replay, etc.) Node table changes: o optionally allocate a h/w key index to node mapping table for the station table using the max key index setting supplied by drivers (note the scan table does not get a map) o defer node table allocation to lateattach so the driver has a chance to set the max key id to size the key index map o while here also defer the aid bitmap allocation o add new ieee80211_find_rxnode_withkey api to find a sta/node entry on frame receive with an optional h/w key index to use in checking mapping table; also updates the map if it does a hash lookup and the found node has a rx key index set in the unicast key; note this work is separated from the old ieee80211_find_rxnode call so drivers do not need to be aware of the new mechanism o move some node table manipulation under the node table lock to close a race on node delete o add ieee80211_node_delucastkey to do the dirty work of deleting unicast key state for a node (deletes any key and handles key map references) Ath driver: o nuke private sc_keyixmap mechansim in favor of net80211 support o update key alloc api These changes close several race conditions for the ath driver operating in ap mode. Other drivers should see no change. Station mode operation for ath no longer uses the key index map but performance tests show no noticeable change and this will be fixed when the scan table is eliminated with the new scanning support.

Previously we allocated a node from the station table, sent the frame (using the node), then released the reference that "held the frame in the table". But while the frame was in flight the node might be reclaimed which could lead to problems.

1.47	23-Nov-2005	dyoung	In ieee80211_init_neighbor, delete unsupported rates from an adhoc node. It's the right thing to do, but it is of pressing importance because SampleRate's ath_rate_ctl_reset() will convert an unsupported rate to an invalid rate-index of 0xff, and pass the index to ath_hal_computetxtime(). ath_hal_computetxtime() does not tolerate an invalid index; the CPU traps a divide-by-zero fault in ath_hal_computetxtime().
1.46	20-Nov-2005	dyoung	Repair adhoc mode. 1 Complete initialization of "faked up" ieee80211_nodes, whose capabilities and other fields are wrong, when we first receive a beacon or probe response from the corresponding neighbor. This entails factoring ieee80211_init_neighbor out of ieee80211_add_neighbor. 2 In adhoc mode, ic->ic_bss is present in the neighbors table, ic->ic_sta, and it is not necessarily the wrong node on which to mark statistics for a rx'd packet. Do not reject ic->ic_bss and fake-up a new node without comparing its MAC address with the address of the sender in the rx'd packet. This fixes a memory leak.

1.41	05-Jul-2005	dyoung	branches: 1.41.2; In ieee80211_refine_node_for_beacon, do not decrease the reference count on the node that is passed in, because it belongs to the driver. Also, do not increase the reference count on the refined node, because ieee80211_refine_node_for_beacon's caller (ieee80211_input) will never decrease the reference count. As a general rule, reference counts are used for driver code to assert ownership of ieee80211_nodes that are shared by the driver and net80211 layer.
1.40	26-Jun-2005	dyoung	Do not build AP support if 'options IEEE80211_NO_HOSTAP'. I will use this in the INSTALL kernel to save some space.

1.37	04-Jan-2005	dyoung	branches: 1.37.2; 1.37.4; IBSS-merge clean-up, inspired by some Linux patches from Jon Anderson (mail@janderson.ca): remove ieee80211_ibss_merge's TSFT argument. Do the TSFT comparison in the drivers (ath, atw). Remove a lot of extraneous debug statements from ieee80211_ibss_merge. Set the ieee80211_node's state to IEEE80211_STA_BSS after it's been copied to the ic_bss, not before. In struct ieee80211_node, make the ni_tstamp field a union of a uint64_t and the 8 TSF octets so that it's easier to compare a neighbor's TSF with the local TSF. Log IBSS merges (Greg Troxel's suggestion). Also log IBSS creation. These are rare and important events that deserve to be logged.
1.36	04-Oct-2004	dyoung	Drivers are not expected to call ieee80211_find_node_for_beacon, so don't increase the reference count on a node before returning it.
1.35	04-Oct-2004	dyoung	Bug fix: in ieee80211_find_txnode, we used to call ieee80211_ref_node(ni) if ni == NULL and the operating mode was not "ad hoc" or "ad hoc demo." That crashed the kernel. Now, if the operating mode is not "ad hoc (demo)," and ni == NULL, return NULL right away. Also, if ieee80211_dup_bss returns NULL, return NULL right away. This doesn't fix a bug, but it makes clear how this works.
1.34	10-Aug-2004	dyoung	Cosmetic: remove extraneous blank line.
1.33	10-Aug-2004	dyoung	Make the node table into an LRU cache: least-recently used nodes are at the end of the node queue. Change the reference-counting discipline: ni->ni_refcnt indicates how many times net80211 has granted ni to the driver. Every node in the table with ni_refcnt=0 is eligible to be garbage-collected. The mere presence of a node in the table does not any longer indicate its auth/assoc state; nodes have a ni_state variable, now. A sysctl, net.link.ieee80211.maxnodecache, controls the maximum LRU cache size. While I am here, patch ieee80211_find_node_for_beacon to do a "best match" by bssid/ssid/channel, not a "perfect match." This keeps net80211 from caching duplicate nodes in the table.
1.32	29-Jul-2004	mycroft	branches: 1.32.2; Whoops, rearrange the function so the TAILQ_EMPTY() DTRT.
1.31	29-Jul-2004	mycroft	Don't reset the inactivity timer every time we create a node -- this could cause us to stall and never time out anything.
1.30	29-Jul-2004	mycroft	Implement passive scanning for APs in station and host-AP mode: ieee80211_input(): * Do not discard management frames in station mode just because they have the wrong BSSID. * Do not discard beacons in station and host-AP mode when not scanning. * Some minor rearrangement. Update node statistics even if the packet is rejected. ieee80211_recv_mgmt(): * Accept probe responses and beacons in station and host-AP even when not scanning. * Do not immediately free the node created by a beacon or probe response. XXX Should I check BSSIDs more carefully in ieee80211_recv_mgmt() -- specifically for ASSOC_RESP, REASSOC_RESP, AUTH, DEAUTH and DISASSOC? Fix a problem with APs that advertise multiple SSIDs: Change the footprint of ieee80211_find_node_with_channel() to take a SSID as well, and, if not empty, compared it with the existing nodes. This causes us to allocate multiple nodes for the same AP. Without this we were only leaving one SSID in the node table, which might not be the desired one, and so the interface would fail to fully initialize. (Reported by he@ with a Cisco 350 AP.)
1.29	28-Jul-2004	dyoung	Always lookup/create a node table entry for Beacons and Probe Responses. Ad hoc mode uses these entries to track network peers. This provides passive-scan information for the current channel in infrastructure mode (XXX really should keep it in a different table). Host APs will someday use these entries to track APs in the same ESS for AP-to-AP bridging.
1.28	26-Jul-2004	mycroft	The adhoc mode changes are seriously broken. In host-AP mode, at least, we must use a full node for received management frames, or we are unable to complete association and talk to the client. I could add an "if mode == HOSTAP" to fix this, but instead I am reverting the change and remanding it to the person who broke it.
1.27	25-Jul-2004	dyoung	Call ieee80211_free_node, not ieee80211_node_leave, on timed-out IBSS nodes. Do not send an EXPIRE-type DEAUTH message when IBSS nodes time-out. This ends the panic that rev 1.25 fixed, but without a dual-use ieee80211_node_leave.
1.26	25-Jul-2004	dyoung	Undo last: Sam Leffler has shown me a better way to avoid ad hoc lossage.
1.25	24-Jul-2004	dyoung	ieee80211_node_leave runs in all modes, not just hostap mode, so it must not IASSERT that it is in hostap mode.
1.24	24-Jul-2004	dyoung	NetBSD does not define ieee80211_node_refcnt(). Use ni->ni_refcnt, instead.
1.23	23-Jul-2004	mycroft	Cleanup of ieee80211_node from madwifi: * Don't use ifp pointers; use ieee80211com. * Implement the locking macros that are used under FreeBSD and Linux.
1.22	23-Jul-2004	mycroft	Changes from madwifi: Abstract some of the node management code into separate functions, and use them throughout, plugging memory leaks. Allocate the AID allocation map dynamically.
1.21	23-Jul-2004	mycroft	IEEE80211_F_WEPON -> IEEE80211_F_PRIVACY
1.20	23-Jul-2004	mycroft	Yet more DPRINTF() cleanup.
1.19	23-Jul-2004	dyoung	Fix ieee80211_needs_rxnode so that net80211 does something akin to a passive scan for APs and IBSSs, always, but without visiting new channels.
1.18	23-Jul-2004	mycroft	Diff reduction vs. madwifi. Change the signature of IEEE80211_DPRINTF() so that it uses a bitmask, and convert some of the if_printf()s to IEEE80211_DPRINTF()s. XXX I'm using a global variable at the moment rather than per-interface.
1.17	23-Jul-2004	dyoung	Don't be so repetitive repetitive in the ieee80211_needs_rxnode synopsis.
1.16	23-Jul-2004	dyoung	Bug fix: in ad hoc mode, the principle of least surprise demands that we create the network with the BSSID preferred by the operator. [Say the operator set the desired BSSID with 'ifconfig atw0 bssid 02:25:25:75:75:75'. If no such network is found during scanning, then create the network with that BSSID.]
1.15	02-Jul-2004	dyoung	Remove a few levels of indentation in ieee80211_find_rxnode by return'ing early.
1.14	09-May-2004	dyoung	In ieee80211_find_rxnode, when we "fake up" a node for an ad hoc peer, we have to copy the "master" rate table to the faked-up node's rate table, or else ath0 will complain, "ath0: bogus xmit rate 0x0". Thank you Konstantin KABASSANOV for reporting this problem.
1.13	06-May-2004	dyoung	Add a sysctl, net.ieee80211.debug, for turning debug messages on and off. Add a sysctl, net.ieee80211.maxinact, for adjusting the node time-out interval. After net.ieee80211.maxinact seconds of inactivity, an AP will purge a peer/client-record. Now the client has to reassociate.
1.12	01-May-2004	dyoung	Doh. Make it compile w/o IEEE80211_DEBUG.
1.11	30-Apr-2004	dyoung	From FreeBSD. Handle ad hoc-mode nodes better. Use FREE/MALLOC instead of free/malloc. Add back _ieee80211_find_node, the helper for ieee80211_find_node.
1.10	13-Jan-2004	dyoung	branches: 1.10.2; NetBSD's KASSERT takes just one argument while FreeBSD's takes two, so I have added IASSERT(cond, complaint) to the compatibility header file and s/KASSERT/IASSERT/'d.
1.9	14-Dec-2003	dyoung	Synchronize with FreeBSD sources from 12 Dec 2003.
1.8	02-Nov-2003	dyoung	Cosmetic: get rid of an indent level in ieee80211_find_txnode by changing an if () ... else to an if () return.
1.7	29-Oct-2003	dyoung	Add ieee80211_find_rxnode and its helper ieee80211_needs_rxnode. 802.11 drivers will use ieee80211_find_rxnode to match each received packet with the ieee80211_node belonging to the sender. The driver will use the ieee80211_node to track the sender's RSSI and other statistics for, e.g., rate adaptation. ieee80211_find_rxnode "fakes-up" missing ieee80211_nodes in IBSS mode and in ad-hoc demo mode when it is appropriate. See the comments in the source. Also add ieee80211_find_txnode, which looks up the ieee80211_node belonging to a MAC destination. ieee80211_find_txnode will also fake-up missing nodes in IBSS/ad-hoc demo mode. In ieee80211_encap, use ieee80211_find_txnode. This fixes the bug in ad hoc packet-transmission reported by Greg Troxel, Urban Boquist, and Kurt Schreiner.
1.6	15-Oct-2003	dyoung	Add WEP shared-key authentication.
1.5	13-Oct-2003	dyoung	More changes to the new 802.11 layer: * Add Kevin Lahey's power-saving support from the old 802.11 layer * Add my stop-gap rate-selection routine, ieee80211_get_rate, from the old 802.11 layer * Also from the old 802.11 layer: factor ieee80211_match_bss out of ieee80211_end_scan, since atw(4) uses it for IBSS merges.
1.4	23-Sep-2003	dyoung	Make ieee80211_unref_node compile. #ifdef __FreeBSD__ a lot of lines, and put the NetBSDisms into the #else half. Add ieee80211_node_{dec,inc}ref to ieee80211_node.h.

This entails factoring ieee80211_init_neighbor out of ieee80211_add_neighbor. 2 In adhoc mode, ic->ic_bss is present in the neighbors table, ic->ic_sta, and it is not necessarily the wrong node on which to mark statistics for a rx'd packet. Do not reject ic->ic_bss and fake-up a new node without comparing its MAC address with the address of the sender in the rx'd packet. This fixes a memory leak.

1.15	04-Jan-2005	dyoung	IBSS-merge clean-up, inspired by some Linux patches from Jon Anderson (mail@janderson.ca): remove ieee80211_ibss_merge's TSFT argument. Do the TSFT comparison in the drivers (ath, atw). Remove a lot of extraneous debug statements from ieee80211_ibss_merge. Set the ieee80211_node's state to IEEE80211_STA_BSS after it's been copied to the ic_bss, not before. In struct ieee80211_node, make the ni_tstamp field a union of a uint64_t and the 8 TSF octets so that it's easier to compare a neighbor's TSF with the local TSF. Log IBSS merges (Greg Troxel's suggestion). Also log IBSS creation. These are rare and important events that deserve to be logged.
1.14	10-Aug-2004	dyoung	Make the node table into an LRU cache: least-recently used nodes are at the end of the node queue. Change the reference-counting discipline: ni->ni_refcnt indicates how many times net80211 has granted ni to the driver. Every node in the table with ni_refcnt=0 is eligible to be garbage-collected. The mere presence of a node in the table does not any longer indicate its auth/assoc state; nodes have a ni_state variable, now. A sysctl, net.link.ieee80211.maxnodecache, controls the maximum LRU cache size. While I am here, patch ieee80211_find_node_for_beacon to do a "best match" by bssid/ssid/channel, not a "perfect match." This keeps net80211 from caching duplicate nodes in the table.
1.13	29-Jul-2004	mycroft	branches: 1.13.2; Implement passive scanning for APs in station and host-AP mode: ieee80211_input(): * Do not discard management frames in station mode just because they have the wrong BSSID. * Do not discard beacons in station and host-AP mode when not scanning. * Some minor rearrangement. Update node statistics even if the packet is rejected. ieee80211_recv_mgmt(): * Accept probe responses and beacons in station and host-AP even when not scanning. * Do not immediately free the node created by a beacon or probe response. XXX Should I check BSSIDs more carefully in ieee80211_recv_mgmt() -- specifically for ASSOC_RESP, REASSOC_RESP, AUTH, DEAUTH and DISASSOC? Fix a problem with APs that advertise multiple SSIDs: Change the footprint of ieee80211_find_node_with_channel() to take a SSID as well, and, if not empty, compared it with the existing nodes. This causes us to allocate multiple nodes for the same AP. Without this we were only leaving one SSID in the node table, which might not be the desired one, and so the interface would fail to fully initialize. (Reported by he@ with a Cisco 350 AP.)
1.12	23-Jul-2004	mycroft	Cleanup of ieee80211_node from madwifi: * Don't use ifp pointers; use ieee80211com. * Implement the locking macros that are used under FreeBSD and Linux.

1.7	29-Oct-2003	dyoung	Add ieee80211_find_rxnode and its helper ieee80211_needs_rxnode. 802.11 drivers will use ieee80211_find_rxnode to match each received packet with the ieee80211_node belonging to the sender. The driver will use the ieee80211_node to track the sender's RSSI and other statistics for, e.g., rate adaptation. ieee80211_find_rxnode "fakes-up" missing ieee80211_nodes in IBSS mode and in ad-hoc demo mode when it is appropriate. See the comments in the source. Also add ieee80211_find_txnode, which looks up the ieee80211_node belonging to a MAC destination. ieee80211_find_txnode will also fake-up missing nodes in IBSS/ad-hoc demo mode. In ieee80211_encap, use ieee80211_find_txnode. This fixes the bug in ad hoc packet-transmission reported by Greg Troxel, Urban Boquist, and Kurt Schreiner.
1.6	15-Oct-2003	dyoung	Add WEP shared-key authentication.

Convert FreeBSD node mutex uses to generic node critical-section protection (ieee80211_node_critsect_begin, _end), replace FreeBSD atomic arithmetic with generic alternative, and implement generics in NetBSD * Provide NetBSD-style 802.11 ioctls * Style nits

This change doesn't yet add support for loading bpf as a module, since drivers can register before bpf is attached. However, callers of bpf can now be modularized. Dynamically loadable bpf could probably be done fairly easily with coordination from the stub driver and the real driver by registering attachments in the stub before the real driver is loaded and doing a handoff. ... and I'm not going to ponder the depths of unload here.

That is, the amount of time reserved after the packet has finished transmitting. Change the arguments to ieee80211_compute_duration: pass the entire packet length, not just the payload length. Add a 'debug' argument to ieee80211_compute_duration and its helper subroutine, ieee80211_compute_duration1. If debug != 0, ieee80211_compute_duration printfs its arguments and several local variables. In rtw(4), load the 802.11 Duration field with the result from ieee80211_compute_duration.

Change the reference-counting discipline: ni->ni_refcnt indicates how many times net80211 has granted ni to the driver. Every node in the table with ni_refcnt=0 is eligible to be garbage-collected. The mere presence of a node in the table does not any longer indicate its auth/assoc state; nodes have a ni_state variable, now. A sysctl, net.link.ieee80211.maxnodecache, controls the maximum LRU cache size. While I am here, patch ieee80211_find_node_for_beacon to do a "best match" by bssid/ssid/channel, not a "perfect match." This keeps net80211 from caching duplicate nodes in the table.

1.9	02-Nov-2003	dyoung	On the output path, save a power-saving station's ieee80211_node in the mbuf's rcvif field so that the driver can get at it.
1.8	29-Oct-2003	dyoung	Add ieee80211_find_rxnode and its helper ieee80211_needs_rxnode. 802.11 drivers will use ieee80211_find_rxnode to match each received packet with the ieee80211_node belonging to the sender. The driver will use the ieee80211_node to track the sender's RSSI and other statistics for, e.g., rate adaptation. ieee80211_find_rxnode "fakes-up" missing ieee80211_nodes in IBSS mode and in ad-hoc demo mode when it is appropriate. See the comments in the source. Also add ieee80211_find_txnode, which looks up the ieee80211_node belonging to a MAC destination. ieee80211_find_txnode will also fake-up missing nodes in IBSS/ad-hoc demo mode. In ieee80211_encap, use ieee80211_find_txnode. This fixes the bug in ad hoc packet-transmission reported by Greg Troxel, Urban Boquist, and Kurt Schreiner.
1.7	15-Oct-2003	dyoung	Add WEP shared-key authentication.
1.6	13-Oct-2003	dyoung	Even more changes to the new 802.11 layer: * Add Kevin Lahey's power-saving support from the old 802.11 layer * Add a FHPARMS or DSPARMS info element to probe responses and beacons as appropriate.
1.5	28-Sep-2003	dyoung	More NetBSD-FreeBSD compatibility changes in the pattern #ifdef __FreeBSD__ /* FreeBSDism / #else / NetBSDism */ #endif An important and non-obvious change is in ieee80211_mgmt_output, #ifdef __FreeBSD__ KASSERT(m->m_pkthdr.rcvif == NULL, ("rcvif not null")); #endif Because NetBSD mbufs are not bzero'd like FreeBSD's, we cannot count on rcvif == NULL.
1.4	14-Sep-2003	dyoung	Insert RCSIDs.
1.3	07-Sep-2003	dyoung	Complete merge.
1.2	07-Sep-2003	dyoung	First stab at producing a unified NetBSD/FreeBSD 802.11 layer, striving to keep the diffs short and simple. * Replace FreeBSDisms (e.g. struct arpcom) with conditionally-compiled NetBSDism (struct ethercom). * Add compatibility shims in ieee80211_compat.: provide NetBSD with if_printf, for example. Convert FreeBSD node mutex uses to generic node critical-section protection (ieee80211_node_critsect_begin, _end), replace FreeBSD atomic arithmetic with generic alternative, and implement generics in NetBSD * Provide NetBSD-style 802.11 ioctls * Style nits

1.16	10-Aug-2004	dyoung	Make the node table into an LRU cache: least-recently used nodes are at the end of the node queue. Change the reference-counting discipline: ni->ni_refcnt indicates how many times net80211 has granted ni to the driver. Every node in the table with ni_refcnt=0 is eligible to be garbage-collected. The mere presence of a node in the table does not any longer indicate its auth/assoc state; nodes have a ni_state variable, now. A sysctl, net.link.ieee80211.maxnodecache, controls the maximum LRU cache size. While I am here, patch ieee80211_find_node_for_beacon to do a "best match" by bssid/ssid/channel, not a "perfect match." This keeps net80211 from caching duplicate nodes in the table.

1.11	27-Jun-2005	dyoung	branches: 1.11.2; rtw: Try to get hardware WEP to work. It seems to work in the RX direction, but not in the TX direction. The net80211 crypto framework doesn't seem to cope very well with the assymetry (I'm probably missing something), so I will use software WEP for now. net80211: In ieee80211_compute_duration, figure out whether to add the WEP header to the packet overhead by checking the WEP bit in the Frame Control field of the 802.11 header, instead of checking the IEEE80211_F_PRIVACY flag. Also, if the WEP bit is present, assume that the frame described by (wh, len) has already already been WEP encapsulated, and adjust the payload length accordingly. XXX that's a grotty hack that I will have to revisit, later.
1.10	22-Jun-2005	dyoung	Resolve conflicts in importation of 18-May-2005 ath(4) / net80211(9) from FreeBSD. Introduce compatibility shims (sys/dev/ic/ath_netbsd.[ch], sys/net80211/ieee80211_netbsd.[ch]). Update drivers (an, atu, atw, awi, ipw, iwi, rtw, wi) for the new net80211(9) API.
1.9	26-Feb-2005	perry	nuke trailing whitespace
1.8	04-Jan-2005	dyoung	branches: 1.8.2; 1.8.4; IBSS-merge clean-up, inspired by some Linux patches from Jon Anderson (mail@janderson.ca): remove ieee80211_ibss_merge's TSFT argument. Do the TSFT comparison in the drivers (ath, atw). Remove a lot of extraneous debug statements from ieee80211_ibss_merge. Set the ieee80211_node's state to IEEE80211_STA_BSS after it's been copied to the ic_bss, not before. In struct ieee80211_node, make the ni_tstamp field a union of a uint64_t and the 8 TSF octets so that it's easier to compare a neighbor's TSF with the local TSF. Log IBSS merges (Greg Troxel's suggestion). Also log IBSS creation. These are rare and important events that deserve to be logged.
1.7	23-Dec-2004	dyoung	Fix a bug in ieee80211_compute_duration: the 802.11 Duration field in an 802.11 unicast data packet is equal to the duration of the SIFS and Acknowledgement. That is, the amount of time reserved after the packet has finished transmitting. Change the arguments to ieee80211_compute_duration: pass the entire packet length, not just the payload length. Add a 'debug' argument to ieee80211_compute_duration and its helper subroutine, ieee80211_compute_duration1. If debug != 0, ieee80211_compute_duration printfs its arguments and several local variables. In rtw(4), load the 802.11 Duration field with the result from ieee80211_compute_duration.
1.6	19-Dec-2004	dyoung	Define for more bits in the Service field of the 802.11 PLCP Header. For use by the subroutine ieee80211_compute_duration, add struct ieee80211_duration, and #define a number of microsecond constants used for the transmit timing of 802.11 packets. Add the subroutine ieee80211_compute_duration, which computes for any packet the appropriate 802.11 Duration field, the PLCP Length field, as well as the Duration and Length fields for an RTS frame. atw(4), rtw(4), future drivers, and possibly ath(4) will share ieee80211_compute_duration.
1.5	28-Jul-2004	dyoung	branches: 1.5.2; Vastly simplify ieee80211_ibss_merge, eliminating the needless callbacks. Change the reference IBSS-merge implementation in atw to match.
1.4	24-Jul-2004	dyoung	Pull the IBSS merge logic out of atw and into net80211, since ath will eventually share it. In the IBSS merge logic, check conditions in a different order so that they run faster in the common case---no merge. Fix the rate-limiting on the debug outputs (enabled by IFF_LINK0).

1.11	22-Jun-2005	dyoung	branches: 1.11.2; Resolve conflicts in importation of 18-May-2005 ath(4) / net80211(9) from FreeBSD. Introduce compatibility shims (sys/dev/ic/ath_netbsd.[ch], sys/net80211/ieee80211_netbsd.[ch]). Update drivers (an, atu, atw, awi, ipw, iwi, rtw, wi) for the new net80211(9) API.
1.10	20-Jun-2005	atatat	Change the rest of the sysctl subsystem to use const consistently. The __UNCONST macro is now used only where necessary and the RW macros are gone. Most of the changes here are consumers of the sysctl_createv(9) interface that now takes a pair of const pointers which used not to be.

1.8	23-Jul-2004	mycroft	branches: 1.8.2; 1.8.6; 1.8.8; Diff reduction vs. madwifi. Change the signature of IEEE80211_DPRINTF() so that it uses a bitmask, and convert some of the if_printf()s to IEEE80211_DPRINTF()s. XXX I'm using a global variable at the moment rather than per-interface.
1.7	25-May-2004	atatat	Sysctl descriptions under net subtree (net.key not done)
1.6	06-May-2004	dyoung	Following Andrew Brown's suggestion, move net.ieee80211 to net.link.ieee80211. The convention is that nodes directly under net are protocol families (PF_*). Also, simplify the sysctl setup for net80211 and rssadapt, following another suggestion by Andrew.
1.5	06-May-2004	dyoung	Create ieee80211_rssadapt_debug to control rssadapt(9) debug messages independently from net80211 debug messages. Create a new sysctl, net.ieee80211.rssadapt.debug, for turning the debug messages on and off. Create a new sysctl, net.ieee80211.rssadapt.expavgctl, to control the rate of decay for the exponential averages used by rssadapt(9).
1.4	29-Mar-2004	dyoung	Get the sense of ra->ra_nok and ra->ra_nfail right. They indicate successes and failures, respectively, not the other way around.
1.3	17-Mar-2004	dyoung	In wi(4), wi_choose_rate used to contain device-independent code. I have pulled that code into the function ieee80211_rssadapt_choose so that I can re-use it in ath(4), atw(4), and in other drivers. In rssadapt(9), I have also created a struct ieee80211_rssadapt_expavgctl that contains parameters for rate adaptation. When IEEE80211_RSSADAPT_DEBUG is enabled, I will using sysctl to expose an ieee80211_rssadapt_expavgctl for each wireless device. Also in rssadapt(9), I have introduced an interpolate() macro which makes the exponential-averaging code more compact.
1.2	07-Dec-2003	dyoung	Oops. Make it compile with 'options IEEE80211_DEBUG'.
1.1	26-Oct-2003	dyoung	Support data-rate adaptation loosely based on the paper "Link Adaptation Strategy for IEEE 802.11 WLAN via Received Signal Strength Measurement" by Javier del Prado Pavon and Sunghyun Choi. This module should provide faster adaptation and higher throughput than Lucent's rate-adaptation scheme. Individual drivers need to be modified to use this module. Patches for wi(4) are forthcoming.

1.35	24-Jun-2023	msaitoh	Fix typo in comment.
1.34	15-Mar-2020	thorpej	Define and implement a locking protocol for the ifmedia / mii layers: - MP-safe drivers provide a mutex to ifmedia that is used to serialize access to media-related structures / hardware regsiters. Converted drivers use the new ifmedia_init_with_lock() function for this. The new name is provided to ease the transition. - Un-converted drivers continue to call ifmedia_init(), which will supply a compatibility lock to be used instead. Several media-related entry points must be aware of this compatibility lock, and are able to acquire it recursively a limited number of times, if needed. This is a SPIN mutex with priority IPL_NET. - This same lock is used to serialize access to PHY registers and other MII-related data structures. The PHY drivers are modified to acquire and release the lock, as needed, and assert the lock is held as a diagnostic aid. The "usbnet" framework has had an overhaul of its internal locking protocols to fit in with the media / mii changes, and the drivers adapted. USB wifi drivers have been changed to provide their own adaptive mutex to the ifmedia later via a new ieee80211_media_init_with_lock() function. This is required because the USB drivers need an adaptive mutex. Besised "usbnet", a few other drivers are converted: vmx, wm, ixgbe / ixv. mcx also now calls ifmedia_init_with_lock() because it needs to also use an adaptive mutex. The mcx driver still needs to be fully converted to NET_MPSAFE.

Also, re-synchronize beacon timer using the TSF in the first beacon received after joining a BSS---this should also help suppress spurious beacon misses. I am hopeful that this will help ath(4) lossage reported by perry@ and smb@. Add new configuration through sysctl. Use a shorter calibration interval until IQ calibration finishes.

While I am here, patch ieee80211_find_node_for_beacon to do a "best match" by bssid/ssid/channel, not a "perfect match." This keeps net80211 from caching duplicate nodes in the table.
1.17	28-Jul-2004	dyoung	branches: 1.17.2; Vastly simplify ieee80211_ibss_merge, eliminating the needless callbacks. Change the reference IBSS-merge implementation in atw to match.
1.16	24-Jul-2004	dyoung	Pull the IBSS merge logic out of atw and into net80211, since ath will eventually share it. In the IBSS merge logic, check conditions in a different order so that they run faster in the common case---no merge. Fix the rate-limiting on the debug outputs (enabled by IFF_LINK0).
1.15	23-Jul-2004	mycroft	Cleanup of ieee80211_node from madwifi: * Don't use ifp pointers; use ieee80211com. * Implement the locking macros that are used under FreeBSD and Linux.
1.14	23-Jul-2004	mycroft	Changes from madwifi: Abstract some of the node management code into separate functions, and use them throughout, plugging memory leaks. Allocate the AID allocation map dynamically.
1.13	23-Jul-2004	mycroft	IEEE80211_F_WEPON -> IEEE80211_F_PRIVACY
1.12	23-Jul-2004	dyoung	Don't #define IEEE80211_DEBUG here.
1.11	23-Jul-2004	mycroft	Diff reduction vs. madwifi. Change the signature of IEEE80211_DPRINTF() so that it uses a bitmask, and convert some of the if_printf()s to IEEE80211_DPRINTF()s. XXX I'm using a global variable at the moment rather than per-interface.
1.10	23-Jul-2004	mycroft	IEEE80211_MAX_AID has been renamed to IEEE80211_AID_MAX.
1.9	16-Jul-2004	dyoung	Move ieee80211_channel definition and channel flags into ieee80211_channel.h, step #2.
1.8	16-Jul-2004	dyoung	Chain ieee80211coms together so that the 802.11 sysctls can walk them all to retrieve their node tables.
1.7	06-May-2004	dyoung	Add a sysctl, net.ieee80211.debug, for turning debug messages on and off. Add a sysctl, net.ieee80211.maxinact, for adjusting the node time-out interval. After net.ieee80211.maxinact seconds of inactivity, an AP will purge a peer/client-record. Now the client has to reassociate.
1.6	30-Apr-2004	dyoung	From FreeBSD. Add protection mode bits. Get rid of the RCVMGT capability.
1.5	14-Dec-2003	dyoung	Synchronize with FreeBSD sources from 12 Dec 2003.
1.4	13-Oct-2003	dyoung	* Add support for frequency-hopping PHY mode. * Do not enable debugging by default w/ IEEE80211_DEBUG. * Add Kevin Lahey's power-saving support from the old 802.11 layer
1.3	14-Sep-2003	dyoung	Insert RCSIDs.
1.2	07-Sep-2003	dyoung	First stab at producing a unified NetBSD/FreeBSD 802.11 layer, striving to keep the diffs short and simple. * Replace FreeBSDisms (e.g. struct arpcom) with conditionally-compiled NetBSDism (struct ethercom). * Add compatibility shims in ieee80211_compat.: provide NetBSD with if_printf, for example. Convert FreeBSD node mutex uses to generic node critical-section protection (ieee80211_node_critsect_begin, _end), replace FreeBSD atomic arithmetic with generic alternative, and implement generics in NetBSD * Provide NetBSD-style 802.11 ioctls * Style nits
