All conflicts were simple overlapping changes except perhaps for the Thunder driver. That driver has a change_mtu method explicitly for sending a message to the hardware. If that fails it returns an error. Normally a driver doesn't need an ndo_change_mtu method becuase those are usually just range changes, which are now handled generically. But since this extra operation is needed in the Thunder driver, it has to stay. However, if the message send fails we have to restore the original MTU before the change because the entire call chain expects that if an error is thrown by ndo_change_mtu then the MTU did not change. Therefore code is added to nicvf_change_mtu to remember the original MTU, and to restore it upon nicvf_update_hw_max_frs() failue. Signed-off-by: David S. Miller

cfg80211: add bitrate for 20MHz MCS 9

2016-11-15T13:34:00+00:00

Some drivers (ath10k) report MCS 9 @ 20MHz, which technically isn't defined. To get more meaningful value than 0 out of this however, just extrapolate a bitrate from ratio of MCS 7 and 9 in channels where it is allowed.

Mostly simple overlapping changes. For example, David Ahern's adjacency list revamp in 'net-next' conflicted with an adjacency list traversal bug fix in 'net'. Signed-off-by: David S. Miller

cfg80211: handle fragmented IEs in splitting

2016-10-27T14:03:27+00:00

The IEs "output" can sometimes combine IEs coming from userspace with IEs generated in the kernel - in particular mac80211 does this for association frames. Add support in this code for the 802.11 IE fragmentation. Signed-off-by: Johannes Berg

cfg80211: validate beacon int as part of iface combinations

2016-10-27T07:18:07+00:00

Remove the pointless checking against interface combinations in the initial basic beacon interval validation, that currently isn't taking into account radar detection or channels properly. Instead, just validate the basic range there, and then delay real checking to the interface combination validation that drivers must do. This means that drivers wanting to use the beacon_int_min_gcd will now have to pass the new_beacon_int when validating the AP/mesh start. Signed-off-by: Johannes Berg

cfg80211: fix beacon interval in interface combination iteration

2016-10-27T07:08:44+00:00

We shouldn't abort the iteration with an error when one of the potential combinations can't accomodate the beacon interval request, we should just skip that particular combination. Fix the code to do so. Signed-off-by: Johannes Berg

cfg80211: fix possible memory leak in cfg80211_iter_combinations()

2016-10-18T06:52:00+00:00

'limits' is malloced in cfg80211_iter_combinations() and should be freed before leaving from the error handling cases, otherwise it will cause memory leak.

cfg80211: support virtual interfaces with different beacon intervals

2016-10-13T12:28:29+00:00

This commit provides a mechanism for the host drivers to advertise the support for different beacon intervals among the respective interface combinations in a group, through NL80211_IFACE_COMB_BI_MIN_GCD (u32). This value will be compared against GCD of all beaconing interfaces of matching combinations. If the driver doesn't advertise this value, the old behaviour where all beacon intervals must be identical is retained. If it is specified, then any beacon interval for an interface in the interface combination as well as the GCD of all active beacon intervals in the combination must be greater or equal to this value.

cfg80211: pass struct to interface combination check/iter

2016-10-13T11:39:49+00:00

Move the growing parameter list to a structure for the interface combination check and iteration functions in cfg80211 and mac80211 to make the code easier to understand. Signed-off-by: Purushottam Kushwaha [edit commit message] Signed-off-by: Johannes Berg

cfg80211: add ability to check DA/SA in A-MSDU decapsulation

2016-10-12T07:19:10+00:00

We should not accept arbitrary DA/SA inside A-MSDUs, it could be used to circumvent protections, like allowing a station to send frames and make them seem to come from somewhere else. Add the necessary infrastructure in cfg80211 to allow such checks, in further patches we'll start using them. Signed-off-by: Johannes Berg
