One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This issue was detected with the help of Coccinelle.

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:

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.

It's not the iwlwifi module that depends on mac80211, but iwlmvm and iwldvm. To reflect this better, make MVM and DVM Kconfig options depend on MAC80211 instead. Signed-off-by:

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".

Assigning mvmsta to be NULL when we are about to exit the function is pointless. Remove it. Move the variable declaration to the scope it is used. Signed-off-by:

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. Signed-off-by:

When building AMSDU for gen2, code uses iwl_tx_cmd. The only updated field is len, which is in the same location, so it is not a bug. However, it is a bit confusing and error prone, so change it. Signed-off-by:

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 7f9a3e15 this causes a warning in wiphy_register, which breaks brcmfmac. Disable the update_connect_param callback when roamoff=0 to fix this.

We used to have many versions of statistics notification coming from the firmware. In one of the cleanup patches, we forgot to clean the code that checks if data->general is set. Since it is always set, remove the check. Signed-off-by:

We may have the L-SIG length depending on the phy_data info type; add it to radiotap when we do. Move getting the phy_data out one layer up and the info type into it so we can use this data more generically. We need to call the iwl_mvm_rx_he() function for other reasons as well, so can't just combine all of that into something like iwl_mvm_parse_phy_data(). Signed-off-by:

The firmware changed the PHY data API, so follow suit. Some data is now available even for HT/VHT frames, so the info type in the metadata was changed. This change isn't backwards compatible, but 1) the firmware with the old API was never released; 2) the only overlap in the info type field is from the old type of TB to the new of HT, so this basically just means that with older FW and newer driver the data will be considered missing. While at it, remove the extra code to set the LTF syms corresponding to the streams and use the data from the device instead - we don't really need this in any case other than when we have it from the device. As the new API gives use the spatial reuse 1-4 fields for trigger-based PPDUs, also expose that to radiotap. Signed-off-by: -

When removing the driver, the following flow can happen: 1. host command is in progress, for example at index 68. 2. RX interrupt is received with the response. 3. Before it is processed, the remove flow kicks in, and calls iwl_pcie_txq_unmap. The function cleans all DMA, and promotes the read pointer to 69. 4. RX thread proceeds with the processing, and is calling iwl_pcie_cmdq_reclaim, which will print this error: iwl_pcie_cmdq_reclaim: Read index for DMA queue txq id (0), index 4 is out of range [0-256] 69 69. Detect this situation, and avoid the print. Change it to warning while at it, to make such issues more noticeable in the future. Signed-off-by:

When traffic load is not low or low latency is active, TCM schedules re-evaluation work so in case traffic stops TCM will detect that traffic load has become low or that low latency is no longer active. However, if TCM is paused when the re-evaluation work runs, it does not re-evaluate and the re-evaluation work is no longer scheduled. As a result, TCM will not indicate that low latency is no longer active or that traffic load is low when traffic stops. Fix this by forcing TCM re-evaluation when TCM is resumed in case low latency is active or traffic load is not low. Signed-off-by:

Now that nvm_calib_ver is not checked in opmodes other than dvm, we can remove it from all irrelevant configurations. Signed-off-by: -
Luca Coelho authored
This function is only half-used by mvm (i.e. only the nvm_version part matters, since the calibration version is irrelevant), so it's pointless to export it from iwlwifi. If mvm uses this function, it has the additional complexity of setting the calib version to a bogus value on all cfg structs. To avoid this, move the function to dvm and make a simple comparison of the nvm_version in mvm instead. Signed-off-by: -
