Commit 5a2a6de6a5 ('mesh: Make inactivity
timer configurable') has a problem on 32 bit systems. Setting
NL80211_MESHCONF_PLINK_TIMEOUT to 0xffffffff causes expiration of STA in
a minute by NL80211_CMD_DEL_STATION event. this is the kernel rule for
STA expiration:
(current jiffies) > (frame Rx jiffies + NL80211_MESHCONF_PLINK_TIMEOUT * 250)
On a 32 bit system, the right side could overflow and be unexpected
small value if NL80211_MESHCONF_PLINK_TIMEOUT is sufficiently large. STA
expiration occurs by this reason.
This patch solves the problem by disabling the STA expiration
functionality in mac80211. However, old kernel does not support
disabling it. If so, this patch sets mac80211 inactivity timer 60
seconds into future from the wpa_supplicant inactivity timer.
And I mis-understood that mesh_max_inactivity=0 disables inactivity
timer in wpa_supplicant. This commit fixes it also.

The correct nl80211 flag for group key management cipher was set only
for BIP (AES-CMAC-128). The same flag needs to be used with the newer
ciphers BIP-CMAC-256, BIP-GMAC-128, and BIP-GMAC-256.

libnl uses a pretty small buffer (32 kB that gets converted to 64 kB) by
default. It is possible to hit that limit in some cases where operations
are blocked, e.g., with a burst of Deauthentication frames to hostapd
and STA entry deletion. Try to increase the buffer to make this less
likely to occur.

Current mesh code uses ap_max_inactivity as inactivity timer. This patch
makes it configurable.
There is another mesh inactivity timer in mac80211. The timer works even
if user_mpm=1. So this patch sets the max value to the timer for
workaround.

Unfortunately, libnl 3.0 has changed the API in a way that is not
backwards compatible by renaming nlmsg_len() to nlmsg_datalen() without
leaving the older nlmsg_len() defined. As such, there does not seem to
be any clean way of using this function without breaking the build with
some libnl versions. For now, replace this call with direct calculation
of the data length since it can be done with a simple one-liner that
compiles with all libnl versions.

While there is no explicit driver capability advertisement for this in
nl80211, the EOPNOTSUPP response can be interpreted as a clear
indication of NL80211_CMD_SET_REKEY_OFFLOAD not being supported. Check
for that and don't try to offload keys again if the driver has not use
for them.

If registering WMM-AC ADDTS response action frame or WMM-AC DELTS
action frame fails, the management frame handler is not being
registered. This results with a segmentation fault when trying to
unsubscribe the handler when the interface is removed.
Fix it by always registering the handler and just returning a negative
value to note that the action frame could not be registered.

dfa8787833 ('nl80211: Implement

It would be at least theoretically possible for the bridge netdev to
have disappeared at the time hostapd processes the RTM newlink/dellink
message. As such, it is better to verify that if_indextoname() actually
returned success before printing the bridge ifname in debug. In
addition, there is not much point trying to add the bridge ifindex into
the list of own ifindexes in case the interface has already been
removed, so skip that part as well.

The local ifindex list needs to be updated only if the current bridge
interface is the correct one. If hostapd is going to move the interface
to another bridge, the old bridge ifindex must not be added. In

be set down to allow bridge removal.

Commit 9f12614b8c ('nl80211: Do not

NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT to disable encryption of EAPOL
frames for WEP IEEE 802.1X. However, it used incorrect key management
suite (IEEE 802.1X with WPA/WPA2 while the non-WPA version is needed
here). Consequently, the no-encrypt flag was never set to the driver
(WPA/WPA2 cases do not meet the WEP as pairwise criteria).

The mesh gate is used to bridge (or route) between mesh network and

It is possible for unmasking of 11b rates to fail if a P2P group is
terminated while the netdev is down (e.g., due to rfkill block). This
could result in the 11b TX rates being left masked for non-P2P
operations. This would be particularly unfortunate for channel 14 use
since OFDM rates are not allowed on channel 14 and only OFDM rates were
configured P2P. This issue showed up, e.g., when running hwsim test case
rfkill_autogo followed by ap_wps_conf_chan14.
It may be possible to allow the failed operation in cfg80211/mac80211,
but it looks better to work around this on wpa_supplicant side as well.
Try to unmask the 11b rates again on the next connection request if the
rate unmasking operation had failed.
