In commit c9e9042994d3 ("ipv4: fix possible seqlock deadlock") I left another places where IP_INC_STATS_BH() were improperly used. udp_sendmsg(), ping_v4_sendmsg() and tcp_v4_connect() are called from process context, not from softirq context.

2013-11-29net: clamp ->msg_namelen instead of returning an errorDan Carpenter
If kmsg->msg_namelen > sizeof(struct sockaddr_storage) then in the original code that would lead to memory corruption in the kernel if you had audit configured. If you didn't have audit configured it was harmless. There are some programs such as beta versions of Ruby which use too large of a buffer and returning an error code breaks them. We should clamp the ->msg_namelen value instead.

2013-11-28genetlink/pmcraid: use proper genetlink multicast APIJohannes Berg
The pmcraid driver is abusing the genetlink API and is using its family ID as the multicast group ID, which is invalid and may belong to somebody else (and likely will.) Make it use the correct API, but since this may already be used as-is by userspace, reserve a family ID for this code and also reserve that group ID to not break userspace assumptions. My previous patch broke event delivery in the driver as I missed that it wasn't using the right API and forgot to update it later in my series. While changing this, I noticed that the genetlink code could use the static group ID instead of a strcmp(), so also do that for the VFS_DQUOT family.

2013-11-25mac80211: minstrel_ht: do not sample unsupported ratesKarl Beldan
ATM minstrel_ht does not check whether a sampling rate is supported. Unsupported rates attempts can trigger when there are holes in bitfields of supported MCSes belonging to the same group (e.g many devices are MCS32 capable without MCS33->39 capable, also we systematically have a hole for CCK rates). Drop any attempts to sample unsupported rates, as suggested by Felix. This is not a problem in minstrel which fills a per STA sample table with only supported rates (though only at init).

2013-11-25mac80211: minstrels: spare numerous useless calls to get_random_bytesKarl Beldan
ATM, only the first array value returned by get_random_bytes is used. This change moves the call to get_random_bytes from the nested loop it is in to its parent. While at it, replace get_random_bytes with prandom_bytes since PRNs are way enough for the selection process. After this, minstrel_ht reclaims 80 PR-bytes instead of 640 R-bytes. minstrels use sample tables to probe different rates in a randomized manner. minstrel_ht inits one single sample table upon registration (during subsys_initcalls) and minstrel uses one per STA addition in minstrel.

2013-11-25mac80211: minstrel_ht: replace some occurences of MCS_GROUP_RATESKarl Beldan

This change replaces such occurences and by doing so allows for different values of MCS_GROUP_RATES (e.g to cope with VHT MCS8,9).

2013-11-25mac80211: add min required channel definition fieldEliad Peller
Add a new field to ieee80211_chanctx_conf to indicate the min required channel configuration. Tuning to a narrower channel might help reducing the noise level and saving some power. The min required channel definition is the max of all min required channel definitions of the interfaces bound to this channel context. In AP mode, use 20MHz when there are no connected station. When a new station is added/removed, calculate the new max bandwidth supported by any of the stations (e.g. 80MHz when 80MHz and 40MHz stations are connected). In other cases, simply use bss_conf.chandef as the min required chandef. Notify drivers about changes to this field by calling drv_change_chanctx with a new CHANGE_MIN_WIDTH notification.
