2019-04-08drivers: Remove explicit invocations of mmiowb()Will Deacon1-2/+0
mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

2015-04-24mac80211: remove support for IFF_PROMISCJohannes Berg1-13/+2
This support is essentially useless as typically networks are encrypted, frames will be filtered by hardware, and rate scaling will be done with the intended recipient in mind. For real monitoring of the network, the monitor mode support should be used instead. Removing it removes a lot of corner cases. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2012-11-09mac80211: clarify interface iteration and make it configurableJohannes Berg1-2/+3
During hardware restart, all interfaces are iterated even though they haven't been re-added to the driver, document this behaviour. The same also happens during resume, which is even more confusing since all of the interfaces were previously removed from the driver. Make this optional so drivers relying on the current behaviour can still use it, but to let drivers that don't want this behaviour disable it. Also convert all API users, keeping the old semantics except in hwsim, where the new normal ones are desired. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Mark keys that might be used to receive management frames so drivers can fall back on software crypto for them if they don't support hardware offload. As the new flag is only set correctly for RX keys and the existing IEEE80211_KEY_FLAG_SW_MGMT flag can only affect TX, also rename the latter to IEEE80211_KEY_FLAG_SW_MGMT_TX.

2012-08-13ath5k: fix spin_lock_irqsave/spin_lock_bh nesting in meshBob Copeland1-3/+2
Lockdep found an inconsistent lock state when joining a mesh with ath5k. The problem is that ath5k takes the lock for its beacon state, ah->block, with spin_lock_irqsave(), while mesh internally takes the sync_offset_lock with spin_lock_bh() in mesh_sync_offset_adjust_tbtt(), which in turn is called under ah->block. This could deadlock if the beacon tasklet was run on the processor that held the beacon lock during the do_softirq() in spin_unlock_bh(). We probably shouldn't hold the lock around the callbacks, but the easiest fix is to switch to spin_lock_bh for ah->block: it doesn't need interrupts disabled anyway as the data in question is only accessed in softirq or process context. Fixes the following lockdep warning: [ 446.892304] WARNING: at kernel/softirq.c:159 _local_bh_enable_ip+0x38/0xa6() [ 446.892306] Hardware name: MacBook1,1 [ 446.892309] Modules linked in: tcp_lp fuse sunrpc cpufreq_ondemand acpi_cpufreq mperf ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 nf_conntrack_ipv4 ip6table_filter nf_defrag_ipv4 xt_state nf_conntrack ip6_tables ext2 arc4 btusb bluetooth snd_hda_codec_idt snd_hda_intel carl9170 snd_hda_codec coretemp joydev ath5k snd_hwdep snd_seq isight_firmware ath snd_seq_device snd_pcm applesmc appletouch mac80211 input_polldev snd_timer microcode cfg80211 snd lpc_ich pcspkr i2c_i801 mfd_core soundcore rfkill snd_page_alloc sky2 tpm_infineon virtio_net kvm_intel kvm i915 drm_kms_helper drm i2c_algo_bit i2c_core video [ 446.892385] Pid: 1892, comm: iw Not tainted 3.6.0-rc1-wl+ #296 [ 446.892387] Call Trace: [ 446.892394] [<c0432958>] warn_slowpath_common+0x7c/0x91 [ 446.892398] [<c04399d7>] ? _local_bh_enable_ip+0x38/0xa6 [ 446.892403] [<c04399d7>] ? _local_bh_enable_ip+0x38/0xa6 [ 446.892459] [<f7f9ae3b>] ? mesh_sync_offset_adjust_tbtt+0x95/0x99 [mac80211] [ 446.892464] [<c043298f>] warn_slowpath_null+0x22/0x24 [ 446.892468] [<c04399d7>] _local_bh_enable_ip+0x38/0xa6 [ 446.892473] [<c0439a52>] local_bh_enable_ip+0xd/0xf [ 446.892479] [<c088004f>] _raw_spin_unlock_bh+0x34/0x37 [ 446.892527] [<f7f9ae3b>] mesh_sync_offset_adjust_tbtt+0x95/0x99 [mac80211] [ 446.892569] [<f7f7650f>] ieee80211_beacon_get_tim+0x28f/0x4e0 [mac80211] [ 446.892575] [<c047ceeb>] ? trace_hardirqs_on_caller+0x10e/0x13f [ 446.892591] [<f7fdc541>] ath5k_beacon_update+0x40/0x26b [ath5k] [ 446.892597] [<c047ad67>] ? lock_acquired+0x1f5/0x21e [ 446.892612] [<f7fdf9fb>] ? ath5k_bss_info_changed+0x167/0x1b2 [ath5k] [ 446.892617] [<c087f9ea>] ? _raw_spin_lock_irqsave+0x78/0x82 [ 446.892632] [<f7fdf9fb>] ? ath5k_bss_info_changed+0x167/0x1b2 [ath5k] [ 446.892647] [<f7fdfa09>] ath5k_bss_info_changed+0x175/0x1b2 [ath5k] [ 446.892651] [<c0479dd4>] ? lock_is_held+0x73/0x7b [ 446.892662] [<c0458fd5>] ? __might_sleep+0xa7/0x17a [ 446.892698] [<f7f5d8f7>] ieee80211_bss_info_change_notify+0x1ed/0x21a [mac80211] [ 446.892703] [<c0449875>] ? queue_work+0x24/0x32 [ 446.892718] [<f7fdf894>] ? ath5k_configure_filter+0x163/0x163 [ath5k] [ 446.892766] [<f7f95fa4>] ieee80211_start_mesh+0xb9/0xbd [mac80211] [ 446.892806] [<f7f6e610>] ieee80211_join_mesh+0x10c/0x116 [mac80211] [ 446.892834] [<f7a96b90>] __cfg80211_join_mesh+0x176/0x1b3 [cfg80211] [ 446.892855] [<f7a96c1c>] cfg80211_join_mesh+0x4f/0x6a [cfg80211] [ 446.892875] [<f7a89891>] nl80211_join_mesh+0x1de/0x1ed [cfg80211] [ 446.892908] [<f7a8db99>] ? nl80211_set_wiphy+0x4cf/0x4cf [cfg80211] [ 446.892919] [<c07cfa36>] genl_rcv_msg+0x1d5/0x1f3 [ 446.892940] [<c07cf861>] ? genl_rcv+0x25/0x25 [ 446.892946] [<c07cf009>] netlink_rcv_skb+0x37/0x78 [ 446.892950] [<c07cf85a>] genl_rcv+0x1e/0x25 [ 446.892955] [<c07cebf3>] netlink_unicast+0xc3/0x12d [ 446.892959] [<c07cee46>] netlink_sendmsg+0x1e9/0x213 [ 446.892966] [<c079f282>] sock_sendmsg+0x79/0x96 [ 446.892972] [<c04eb90d>] ? might_fault+0x9d/0xa3 [ 446.892978] [<c07a81d8>] ? copy_from_user+0x8/0xa [ 446.892983] [<c07a852c>] ? verify_iovec+0x43/0x77 [ 446.892987] [<c079f4d8>] __sys_sendmsg+0x180/0x215 [ 446.892993] [<c045f107>] ? sched_clock_cpu+0x134/0x144 [ 446.892997] [<c047992f>] ? trace_hardirqs_off+0xb/0xd [ 446.893002] [<c047bf88>] ? __lock_acquire+0x46b/0xb6e [ 446.893006] [<c047992f>] ? trace_hardirqs_off+0xb/0xd [ 446.893010] [<c045f149>] ? local_clock+0x32/0x49 [ 446.893015] [<c0479ec1>] ? lock_release_holdtime.part.9+0x4b/0x51 [ 446.893020] [<c0479dd4>] ? lock_is_held+0x73/0x7b [ 446.893025] [<c050d127>] ? fcheck_files+0x97/0xcd [ 446.893029] [<c050d4df>] ? fget_light+0x2d/0x81 [ 446.893034] [<c07a01f3>] sys_sendmsg+0x3b/0x52 [ 446.893038] [<c07a07b4>] sys_socketcall+0x238/0x2a2 [ 446.893044] [<c0885edf>] sysenter_do_call+0x12/0x38 [ 446.893047] ---[ end trace a9af5998f929270f ]--- [ 447.627222] [ 447.627232] ================================= [ 447.627237] [ INFO: inconsistent lock state ] [ 447.627244] 3.6.0-rc1-wl+ #296 Tainted: G W [ 447.627248] --------------------------------- [ 447.627253] inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} usage.

TSF can be kept per vif. Add ieee80211_vif param to set/get/reset_tsf, and move the debugfs entries to the per-vif directory. Update all the drivers that implement these callbacks. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-08-08ath5k: clean up base.h and its usePavel Roskin1-0/+2
Remove unnecessary includes from base.h. Add includes to other files as necessary. Don't include base.h unless needed. Move declarations for functions in base.c from ath5k.h to base.h. Use a better named define to protect base.h against double inclusion. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-08-08ath5k: remove unused and write-only structures and fieldsPavel Roskin1-3/+0
struct ath5k_avg_val is unused. In struct ath5k_hw, lladdr, ah_radar and ah_mac_revision are write-only, rxbufsize is unused, ah_phy is write-only and referenced by unused macros. In struct ath5k_vif, lladdr is write-only. Remove AR5K_TUNE_RADAR_ALERT, which has no effect.

2011-07-20ath5k: merge ath5k_hw and ath5k_softcPavel Roskin1-124/+119
Both ath5k_hw and ath5k_softc represent one instance of the hardware. This duplication is historical and is not needed anymore. Keep the name "ath5k_hw" for the merged structure and "ah" for the variable pointing to it. "ath5k_hw" is shorter than "ath5k_softc", more descriptive and more widely used. Put the combined structure to ath5k.h where the old ath5k_softc used to be. Move some code from base.h to ath5k.h as needed. Remove memory allocation for struct ath5k_hw and the corresponding error handling. Merge iobase and ah_iobase fields.

2011-06-17ath5k: minor cleanupPavel Roskin1-4/+2
Move an extern variable declaration to a header file. Prefix all functions with "ath5k_". Make ath5k_intr() static. Remove unneeded forward declarations. Remove pointless "extern" in a function declaration. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-04-12ath5k: fix slot time handlingFelix Fietkau1-0/+9
Set the slot time based on the mac80211 short slot vs long slot setting instead of just forcing long slot for all CCK-enabled channels. This slightly improves 802.11g mode performance in in my tests.

2011-03-07ath5k: Put hardware in PROMISC mode if there is more than 1 stations.Ben Greear1-2/+17
It seems ath5k has issues receiving broadcast packets (ARPs) when using multiple STA interfaces associated with multiple APs. This patch ensures the NIC is always in PROMISC mode if there are more than 1 stations associated. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W.

2011-02-25mac80211: make tx() operation return voidJohannes Berg1-3/+3
The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.

2011-01-28ath5k: Fix short and long retry configurationBruno Randolf1-0/+9
The register definition for retry configuration on AR5212 was wrong, and simply copied over from AR5210. Update the register definitions from the documentation. Let the short and long retries be configured from mac80211 and use the standard values of 7 and 4 by default. Also we need to make sure we don't export more retries than we are configured for to mac80211 (and the rate module) in hw->max_rate_tries. Also clean up the code by removing unused defines and variables and drop the different values for "station retries" - if these need to be different it can be handled tru ah_retry_long/short.
