2018-12-20iwlwifi: mvm: clean up SSN incrementationSara Sharon
Sometimes, due to SCD bug, we need to start the queue with an higher SSN. The queue allocation function currently increments the SSN in the packet itself, but it is pointless, since this value is overridden later by iwl_mvm_tx_mpdu with the value from mvmsta->tid_data[tid].seq_number. Updating tid data is sufficient. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-12-20iwlwifi: pcie: lock txq a bit later in reclaim codeSara Sharon
In reclaim code, we don't need to take the queue lock for waking the queue. The code section is executed only when the tx path is stopped, and since the reclaim path is not executed in parallel to itself, no one can update the queue pointers, and accessing them is safe without a lock.

2018-12-20iwlwifi: make MVM and DVM depend on MAC80211Luca Coelho

2018-12-20iwlwifi: mvm: fix setting HE ppe FW configNaftali Goldstein
The FW expects to get the ppe value for each NSS-BW pair in the same format as in the he phy capabilities IE, which means that a value of 0 implies ppe should be used for BPSK (mcs 0). If there are no PPE thresholds in the IE, or if for some NSS-RU pair there's no threshold set for it (this could happen because it's a variable-sized field), it means no PPE should not be used for that pair, so the value sent to FW should be 7 which corresponds to "none".

2018-12-20iwlwifi: mvm: remove dead codeSara Sharon
In iwl_mvm_tx_skb_non_sta(), in case of managed interface, the AP station was supposed to be used for multicast frames instead of the auxiliary station to avoid frames possibly sent to an absent P2P GO. However, when moving to DQA mode, this was broken as no valid queue was assigned. This is fixed by a recent patch that directs all non-offchannel traffic to ap station earlier in the TX path. However, the broken, and now dead code, remained. Remove it.

2018-12-20cw1200: Fix concurrency use-after-free bugs in cw1200_hw_scan()Jia-Ju Bai
The function cw1200_bss_info_changed() and cw1200_hw_scan() can be concurrently executed. The two functions both access a possible shared variable "frame.skb". This shared variable is freed by dev_kfree_skb() in cw1200_upload_beacon(), which is called by cw1200_bss_info_changed(). The free operation is protected by a mutex lock "priv->conf_mutex" in cw1200_bss_info_changed(). In cw1200_hw_scan(), this shared variable is accessed without the protection of the mutex lock "priv->conf_mutex". Thus, concurrency use-after-free bugs may occur. To fix these bugs, the original calls to mutex_lock(&priv->conf_mutex) and mutex_unlock(&priv->conf_mutex) are moved to the places, which can protect the accesses to the shared variable.

When the update_connect_param callback is set, nl80211 expects the flag WIPHY_FLAG_SUPPORTS_FW_ROAM to be set as well. However, this flag is only set when modparam roamoff=0, while the callback is set unconditionally. Since commit 7f9a3e150ec7 this causes a warning in wiphy_register, which breaks brcmfmac.

2018-12-19gro_cell: add napi_disable in gro_cells_destroyLorenzo Bianconi
Add napi_disable routine in gro_cells_destroy since starting from commit c42858eaf492 ("gro_cells: remove spinlock protecting receive queues") gro_cell_poll and gro_cells_destroy can run concurrently on napi_skbs list producing a kernel Oops if the tunnel interface is removed while gro_cell_poll is running. The following Oops has been triggered removing a vxlan device while the interface is receiving traffic [ 5628.948853] BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 [ 5628.949981] PGD 0 P4D 0 [ 5628.950308] Oops: 0002 [#1] SMP PTI [ 5628.950748] CPU: 0 PID: 9 Comm: ksoftirqd/0 Not tainted 4.20.0-rc6+ #41 [ 5628.952940] RIP: 0010:gro_cell_poll+0x49/0x80 [ 5628.955615] RSP: 0018:ffffc9000004fdd8 EFLAGS: 00010202 [ 5628.956250] RAX: 0000000000000000 RBX: ffffe8ffffc08150 RCX: 0000000000000000 [ 5628.957102] RDX: 0000000000000000 RSI: ffff88802356bf00 RDI: ffffe8ffffc08150 [ 5628.957940] RBP: 0000000000000026 R08: 0000000000000000 R09: 0000000000000000 [ 5628.958803] R10: 0000000000000001 R11: 0000000000000000 R12: 0000000000000040 [ 5628.959661] R13: ffffe8ffffc08100 R14: 0000000000000000 R15: 0000000000000040 [ 5628.960682] FS: 0000000000000000(0000) GS:ffff88803ea00000(0000) knlGS:0000000000000000 [ 5628.961616] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 5628.962359] CR2: 0000000000000008 CR3: 000000000221c000 CR4: 00000000000006b0 [ 5628.963188] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 5628.964034] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 5628.964871] Call Trace: [ 5628.965179] net_rx_action+0xf0/0x380 [ 5628.965637] __do_softirq+0xc7/0x431 [ 5628.966510] run_ksoftirqd+0x24/0x30 [ 5628.966957] smpboot_thread_fn+0xc5/0x160 [ 5628.967436] kthread+0x113/0x130 [ 5628.968283] ret_from_fork+0x3a/0x50 [ 5628.968721] Modules linked in: [ 5628.969099] CR2: 0000000000000008 [ 5628.969510] ---[ end trace 9d9dedc7181661fe ]--- [ 5628.970073] RIP: 0010:gro_cell_poll+0x49/0x80 [ 5628.972965] RSP: 0018:ffffc9000004fdd8 EFLAGS: 00010202 [ 5628.973611] RAX: 0000000000000000 RBX: ffffe8ffffc08150 RCX: 0000000000000000 [ 5628.974504] RDX: 0000000000000000 RSI: ffff88802356bf00 RDI: ffffe8ffffc08150 [ 5628.975462] RBP: 0000000000000026 R08: 0000000000000000 R09: 0000000000000000 [ 5628.976413] R10: 0000000000000001 R11: 0000000000000000 R12: 0000000000000040 [ 5628.977375] R13: ffffe8ffffc08100 R14: 0000000000000000 R15: 0000000000000040 [ 5628.978296] FS: 0000000000000000(0000) GS:ffff88803ea00000(0000) knlGS:0000000000000000 [ 5628.979327] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 5628.980044] CR2: 0000000000000008 CR3: 000000000221c000 CR4: 00000000000006b0 [ 5628.980929] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 5628.981736] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 5628.982409] Kernel panic - not syncing: Fatal exception in interrupt [ 5628.983307] Kernel Offset: disabled Fixes: c42858eaf492 ("gro_cells: remove spinlock protecting receive queues") Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

The MAC Reset was noticed to erase important EEPROM settings. It is also unnecessary since a chip wide reset was done earlier in initialization, and that reset preserves EEPROM settings.

When the completion queue of the RQ is empty, do not immediately return. If left-over decompressed CQEs (from the previous cycle) were processed, need to go to the finalization part of the poll function. Bug exists only when CQE compression is turned ON.
