mac80211 do not check the return code now, what if mac80211 does start using the return code? IEEE80211_AMPDU_TX_OPERATIONAL is a valid action, just iwlwifi driver do not need to take any action for it; so instead of return "-EINVAL", it is a good program practice to return "-EOPNOTSUPP" to make sure mac80211 will not get wrong impression.

sparse pointed out that I made a mistake converting the return value of ieee80211_assoc_success to bool, this place should return false instead of one of the enum values (which would be true). Signed-off-by:

Like how TX reclaim is done in a tasklet, move receive processing to tasklet context as well. This can have nice benefits for CPU utilisation and throughput, especially at 3-stream rates. (Use the same CLEAR_SEL trick as the TX reclaim tasklet does, to avoid having to touch the interrupt mask registers.) Signed-off-by:

By making use of the CLEAR_SEL feature of the mwl8k host interface interrupt controller, we can keep the TX_DONE interrupt source masked while the transmit reclaim tasklet is running (NAPI style) without having to touch the interrupt controller's interrupt mask register when entering or exiting polling mode, and without having to do any more register reads/writes than we do now. When CLEAR_SEL is enabled on the TX_DONE interrupt source, reading the interrupt status register will clear the TX_DONE status bit if it was set, allowing it to be set again if a new TX_DONE event arrives while we are running the TX reclaim tasklet, but such a new event will then not trigger another PCI interrupt until a zero is written to the TX_DONE interrupt status register bit. I.e., if we write a zero to the TX_DONE interrupt source bit in the interrupt status register when the TX reclaim tasklet thinks it's done, a PCI interrupt will be triggered if a new TX_DONE event arrived from the hardware between us deciding that there is no more work to do and re-enabling the TX_DONE interrupt source, thereby avoiding the classic NAPI poll mode exit race that would otherwise occur.

STA firmware uses UPDATE_STADB to manipulate the hardware station database, whereas AP firmware uses SET_NEW_STN -- this implements the latter, and hooks it into mwl8k_sta_notify(), to be used if we're running on AP firmware. Signed-off-by:

As with the STA version, unicast will use auto rate adaptation, but the AP version allows setting the rates to be used for management and multicast transmissions, which can be set based on the BSS basic rate set. Signed-off-by:
-
Lennert Buytenhek authored
As we always use the auto rate adaptation feature and never pass in a rate table, USE_FIXED_RATE can be simplified somewhat. While we're at it, rename it to *_sta, as this is the STA version of the command. Signed-off-by:

While it is reasonable to expect that at least one transmit ring entry will be processed per second while we are waiting for the transmit rings to drain, the firmware can end up doing batching of transmit ring status writeback, which means that the transmit rings can appear stuck for more than a second at a time. Bump the TX drain wait timeout up from 1 to 5 seconds to account for this. Signed-off-by:

The comment and code in mwl8k_cmd_set_edca_params() suggest that the mapping between SET_EDCA_PARAMS queue numbers and transmit rings isn't actually 1:1, while tests show that the mapping is in fact 1:1. So, get rid of the transmit queue 0/1 swapping. Signed-off-by:

If frames are transmitted on 4-addr ap vlan interfaces with no station, they end up being transmitted unencrypted, even if the ap interface uses WPA. This patch add some sanity checking to make sure that this does not happen. Signed-off-by:

Since the per-vif station changes, sta_info_get on the ap sdata no longer returns entries for stations on ap vlans. This causes issues with hostapd, which currently always passes the ap interface name to nl80211 calls. This patch provides bug compatibility with the earlier versions until hostapd is fixed. Signed-off-by:
-
Felix Fietkau authored
To detect incoming 4-addr stations, hostapd needs to receive a 4-addr data frame from the remote station, so that it can create the AP VLAN for it. With this patch, the mlme code emits a 4-addr nullfunc frame immediately after assoc. On the AP side it also drops 4-addr nullfunc frames to the cooked monitor mode interface, if the interface hasn't been fully set up to receive 4-addr data frames yet. Signed-off-by:

This enhances the way we parse country IEs to minimize the number of regulatory rules that we create. It also fixes our current implementation which treated country IE triplets with only one channel as one independed regulatory rule even though adjecent rules were also being provided. Without this patch APs which send country IE information with a channel triplet for each individual channel will force cfg80211 to deny HT40 operation as a regulatory rule would have been created independently for each channel and as such configured only for 20 MHz operation. Although 802.11n APs which send country IEs triplets in this fassion are likely rare Benoit reports this against the Ubiquity NanoStation M5, with Country "FR" and HT40 enabled. Since we now have a helper which parses the triplets in intermediate steps we now take care extra care to process padding. Reported-by:

The max power from each country IE triplet was being ignored. This fix isn't critical as CRDA was always being used for the lower limit, but we should process it in case the AP still wants to decrease power output even more for whatever reason. Reported-by:

Kalle and Lennert reported problems with the new work code, and at least Kalle's problem I was able to trace to a missing jiffies initialisation. I also ran into a problem where occasionally I couldn't connect, which seems fixed with kicking the work items after scanning. Finally, also add some sanity checking code to verify that we're not adding work items while an interface is down -- that case could lead to something similar to what Lennert was seeing. There still seems to be a race condition that we're trying to figure out separately. Signed-off-by:

Store information elements from Beacon and Probe Response frames in separate buffers to allow both sets to be made available through nl80211. This allows user space applications to get access to IEs from Beacon frames even if we have received Probe Response frames from the BSS. Previously, the IEs from Probe Response frames would have overridden the IEs from Beacon frames. This feature is of somewhat limited use since most protocols include the same (or extended) information in Probe Response frames. However, there are couple of exceptions where the IEs from Beacon frames could be of some use: TIM IE is only included in Beacon frames (and it would be needed to figure out the DTIM period used in the BSS) and at least some implementations of Wireless Provisioning Services seem to include the full IE only in Beacon frames). The new BSS attribute for scan results is added to allow both the IE sets to be delivered. This is done in a way that maintains the previously used behavior for applications that are not aware of the new NL80211_BSS_BEACON_IES attribute. Signed-off-by:

In various cases wl1251_op_bss_info_changed() did not call elp_sleep() after an error was noticed. Fix it by using correct goto label. The bug was a theoretical one, in practise it doesn't matter because if commands start returning errors there will be lots of other problems. Signed-off-by:

The current scanning code wasn't following the preferred style. Move code related to scan and trigger scan to commans to wl1251_cmd.c. Because there's now less code in wl1251_hw_scan(), the function can be now merged with wl1251_op_hw_scan(). Signed-off-by:
