Instead of having a lot of places that free ignored requests and then return REG_REQ_OK, make reg_process_hint() process REG_REQ_IGNORE by freeing the request, and let functions it calls return that instead of freeing. This also fixes a leak when a second (different) country IE hint was ignored. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

If there's a built-in regulatory database, there may be little point in also calling out to CRDA and failing if the system is configured that way. Allow removing CRDA support to save ~1K kernel size. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

When the functions reg_set_rd_driver() and reg_set_rd_country_ie() return with an error, the calling function already restores data by calling restore_regulatory_settings(), so there's no need to also schedule a timeout (which would lead to other side effects such as indicating CRDA failed, which clearly isn't true.) Remove the scheduling. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Instead of searching the built-in database only in the worker, search it directly and return an error if the entry cannot be found (or memory cannot be allocated.) This means that builtin database queries no longer rely on the timeout. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

As this API has never really seen any use and most drivers don't ever use the value derived from it, remove it. Change the only driver using it (rt2x00) to simply use the DTIM period instead of the "max sleep" time. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

If multiple scan plans were set for scheduled scan, do not restart scheduled scan on reconfig because it is possible that some scan plans were already completed and there is no need to run them all over again. Instead, notify userspace that scheduled scan stopped so it can configure new scan plans for scheduled scan.

Avraham Stern authored
Add the option to configure multiple 'scan plans' for scheduled scan. Each 'scan plan' defines the number of scan cycles and the interval between scans. The scan plans are executed in the order they were configured. The last scan plan will always run infinitely and thus defines only the interval between scans. The maximum number of scan plans supported by the device and the maximum number of iterations in a single scan plan are advertised to userspace so it can configure the scan plans appropriately. When scheduled scan results are received there is no way to know which scan plan is being currently executed, so there is no way to know when the next scan iteration will start. This is not a problem, however. The scan start timestamp is only used for flushing old scan results, and there is no difference between flushing all results received until the end of the previous iteration or the start of the current one, since no results will be received in between.

For location and connectivity services, userspace would often like to know the time when the BSS was last seen. The current "last seen" value is calculated in a way that makes it less useful, especially if the system suspended in the meantime. Add the ability for the driver to report a real CLOCK_BOOTTIME stamp that can then be reported to userspace (if present). Drivers wishing to use this must be converted to the new API to call cfg80211_inform_bss_data() or cfg80211_inform_bss_frame_data(). They need to ensure the reported value is accurate enough even when the frame might have been buffered in the device (e.g. firmware.)

Currently it's possible for someone to send a vlan range to the kernel with the pvid flag set which will result in the pvid bouncing from a vlan to vlan and isn't correct, it also introduces problems for hardware where it doesn't make sense having more than 1 pvid. iproute2 already enforces this, so let's enforce it on kernel-side as well.

Eric W. Biederman says: ==================== net: Pass net into defragmentation This is the next installment of my work to pass struct net through the output path so the code does not need to guess how to figure out which network namespace it is in, and ultimately routes can have output devices in another network namespace. In netfilter and af_packet we defragment packets in the output path, and there is the usual amount of confusion about how to compute which net we are processing the packets in. This patchset clears that confusion up by explicitly passing in struct net in ip_defrag, ip_check_defrag, and nf_ct_frag6_gather. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Eric W. Biederman authored
The function nf_ct_frag6_gather is called on both the input and the output paths of the networking stack. In particular ipv6_defrag which calls nf_ct_frag6_gather is called from both the the PRE_ROUTING chain on input and the LOCAL_OUT chain on output. The addition of a net parameter makes it explicit which network namespace the packets are being reassembled in, and removes the need for nf_ct_frag6_gather to guess. Signed-off-by: "Eric W.

The function ip_defrag is called on both the input and the output paths of the networking stack. In particular conntrack when it is tracking outbound packets from the local machine calls ip_defrag. So add a struct net parameter and stop making ip_defrag guess which network namespace it needs to defragment packets in. Signed-off-by: "Eric W.

ip_call_ra_chain is called early in the forwarding chain from ip_forward and ip_mr_input, which makes skb->dev the correct expression to get the input network device and dev_net(skb->dev) a correct expression for the network namespace the packet is being processed in.

Recent TCP listener patches exposed a prior af_packet bug : match_fanout_group() blindly assumes it is always safe to cast sk to a packet socket to compare fanout with af_packet_priv But SYNACK packets can be sent while attached to request_sock, which are smaller than a "struct sock".

This patch allows configuring how the source address of ICMP redirect messages is selected; by default the old behaviour is retained, while setting icmp_redirects_use_orig_daddr force the usage of the destination address of the packet that caused the redirect. The new behaviour fits closely the RFC 5798 section 8.1.1, and fix the following scenario: Two machines are set up with VRRP to act as routers out of a subnet, they have IPs x.x.x.1/24 and x.x.x.2/24, with VRRP holding on to x.x.x.254/24. If a host in said subnet needs to get an ICMP redirect from the VRRP router, i.e. to reach a destination behind a different gateway, the source IP in the ICMP redirect is chosen as the primary IP on the interface that the packet arrived at, i.e. x.x.x.1 or x.x.x.2. The host will then ignore said redirect, due to RFC 1122 section 3.2.2.2, and will continue to use the wrong next-op. Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.

Eric Dumazet says: ==================== tcp: better smp listener behavior As promised in last patch series, we implement a better SO_REUSEPORT strategy, based on cpu hints if given by the application. We also moved sk_refcnt out of the cache line containing the lookup keys, as it was considerably slowing down smp operations because of false sharing. This was simpler than converting listen sockets to conventional RCU (to avoid sk_refcnt dirtying) Could process 6.0 Mpps SYN instead of 4.2 Mpps on my test server. ==================== Signed-off-by: David S.
