Currently the debugfs entry for starting aggregation session starts it with timeout of 5 seconds. Allow opening a session with a custom timeout (according to spec 0 is no timeout). while at it, refactor the function and remove the magic numbers. Signed-off-by:

There were a few issues that were slowing down the process of finding the optimal rate, especially on devices with multi-rate retry limitations: When max_tp_rate[0] was slower than max_tp_rate[1], the code did not sample max_tp_rate[1], which would often allow it to switch places with max_tp_rate[0] (e.g. if only the first sampling attempts were bad, but the rate is otherwise good). Also, sample attempts of rates between max_tp_rate[0] and [1] were being ignored in this case, because the code only checked if the rate was slower than [1]. Fix this by checking against the fastest / second fastest max_tp_rate instead of assuming a specific order between the two. In my tests this patch significantly reduces the time until minstrel_ht finds the optimal rate right after assoc Signed-off-by:

The MCS bandwidth part of the radiotap header is 2 bits wide. The full 2 bit have to compared against IEEE80211_RADIOTAP_MCS_BW_40 and not only if the first bit is set. Otherwise IEEE80211_RADIOTAP_MCS_BW_40 can be confused with IEEE80211_RADIOTAP_MCS_BW_20U. Fixes: dfdfc2be ("mac80211: Parse legacy and HT rate in injected frames") Signed-off-by:

Introducing a new feature that the driver can use to indicate the driver/firmware supports configuration of BSS selection criteria upon CONNECT command. This can be useful when multiple BSS-es are found belonging to the same ESS, ie. Infra-BSS with same SSID. The criteria can then be used to offload selection of a preferred BSS. Reviewed-by:

Some devices, like iwlwifi, have RSS queues. This may cause a situation where a disassociation is handled in control path and results in station removal while there are prior RX frames that were still not processed in other queues. When they will be processed the station will be gone, and the frames will be dropped. Add a synchronization interface to avoid that. When driver returns from the synchronization mac80211 may remove the station. Signed-off-by:

In the time since the mesh path table was implemented as an RCU-traversable, dynamically growing hash table, a generic RCU hashtable implementation was added to the kernel. Switch the mesh path table over to rhashtable to remove some code and also gain some features like automatic shrinking. Cc: Thomas Graf <tgraf@suug.ch> Cc: netdev@vger.kernel.org Signed-off-by:

In certain cases, the 802.11 mesh pathtable code wants to iterate over all of the entries in the forwarding table from the receive path, which is inside an RCU read-side critical section. Enable walks inside atomic sections by allowing GFP_ATOMIC allocations for the walker state. Change all existing callsites to pass in GFP_KERNEL. Acked-by:

The mesh path table uses a struct mesh_node in its hlists in order to support a resizable hash table: the mesh_node provides an indirection to the actual mesh path so that two different bucket lists can point to the same path entry. However, for the known gates list, we don't need this indirection because there is ever only one list. So we can just embed the hlist_node in the mesh path itself, which simplifies things a bit and saves a linear search whenever we need to find an item in the list. Signed-off-by:

Bob Copeland authored
The mesh path and mesh gate hashtables are global, containing all of the mpaths for every mesh interface, but the paths are all tied logically to a single interface. The common case is just a single mesh interface, so optimize for that by moving the global hashtable into the per-interface struct. Doing so allows us to drop sdata pointer comparisons inside the lookups and also saves a few bytes of BSS and data. Signed-off-by:

This allows scans for a specific BSSID to be optimized by the user space application by requesting the driver to set the Probe Request frame BSSID field (Address 3) to the specified BSSID instead of the wildcard BSSID. This prevents other APs from replying which reduces airtime need and latency in getting the response from the target AP through. This is an optimization and as such, it is acceptable for some of the drivers not to support the mechanism. If not supported, the wildcard BSSID will be used and more responses may be received.

When HW crypto is used, there's no need for the CCMP/GCMP MIC to be available to mac80211, and the hardware might have removed it already after checking. The MIC is also useless to have when the frame is already decrypted, so allow indicating that it's not present. Since we are running out of bits in mac80211_rx_flags, make the flags field a u64.

Newer Fedora and OpenSUSE didn't boot with my standard configuration. It took me some time to figure out why, in fact I had to write a script to try different config options systematically. The problem is that something (systemd) in dracut depends on CONFIG_FHANDLE, which adds open by file handle syscalls. While it is set in defconfigs it is very easy to miss when updating older configs because it is not default y. Make it default y and also depend on EXPERT, as dracut use is likely widespread.

Commit bb29902a ("oom, oom_reaper: protect oom_reaper_list using simpler way") has simplified the check for tasks already enqueued for the oom reaper by checking tsk->oom_reaper_list != NULL. This check is not sufficient because the tsk might be the head of the queue without any other tasks queued and then we would simply lockup looping on the same task. Fix the condition by checking for the head as well. Fixes: bb29902a ("oom, oom_reaper: protect oom_reaper_list using simpler way") Signed-off-by:
