2017-06-14net: don't global ICMP rate limit packets originating from loopbackJesper Dangaard Brouer
Florian Weimer seems to have a glibc test-case which requires that loopback interfaces does not get ICMP ratelimited. This was broken by commit c0303efeab73 ("net: reduce cycles spend on ICMP replies that gets rate limited"). An ICMP response will usually be routed back-out the same incoming interface. Thus, take advantage of this and skip global ICMP ratelimit when the incoming device is loopback. In the unlikely event that the outgoing it not loopback, due to strange routing policy rules, ICMP rate limiting still works via peer ratelimiting via icmpv4_xrlim_allow(). Thus, we should still comply with RFC1812 (section 4.3.2.8 "Rate Limiting"). This seems to fix the reproducer given by Florian. While still avoiding to perform expensive and unneeded outgoing route lookup for rate limited packets (in the non-loopback case).

2017-06-14net_sched: move tcf_lock down after gen_replace_estimator()WANG Cong
Laura reported a sleep-in-atomic kernel warning inside tcf_act_police_init() which calls gen_replace_estimator() with spinlock protection. It is not necessary in this case, we already have RTNL lock here so it is enough to protect concurrent writers. For the reader, i.e. tcf_act_police(), it needs to make decision based on this rate estimator, in the worst case we drop more/less packets than necessary while changing the rate in parallel, it is still acceptable.

Since the syscall doesn't enforce a minimum size of the corresponding memory region, very short sockaddrs (zero or one byte long) result in operating on uninitialized memory while referencing sa_family.

2017-06-13HID: let generic driver yield control iff specific driver has been enabledJiri Kosina
There are many situations where generic HID driver provides some basic level of support for certain device, but later this support (usually by implementing vendor-specific extensions of HID protocol) is extended and the support moved over to a separate (usually per-vendor) specific driver. This might bring a rather unpleasant suprise for users, as all of a sudden there is a new config option they have to enable in order to get any support for their device whatsoever, although previous kernel versions provided basic support through the generic driver. Which is rightfully seen as a regression. Fix this by including the entry for a particular device in hid_have_special_driver[] iff the specific config option has been specified, and let generic driver handle the device otherwise. Also make the behavior of hid_scan_report() (where the same decision is being taken on a per-report level) consistent. While at it, reshuffle the hid_have_special_driver[] a bit to restore the alphabetical ordering (first order by config option, and within those sections order by VID). This is considered a short-term solution, before generic way of giving precedence to special drivers and falling back to generic driver is figured out. While at it, fixup a missing entry for GFRM driver; thanks to Hans de Geode for spotting this (and for discovering a few issues in the conversion). Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2017-06-13mac80211: don't send SMPS action frame in AP mode when not neededEmmanuel Grumbach
mac80211 allows to modify the SMPS state of an AP both, when it is started, and after it has been started. Such a change will trigger an action frame to all the peers that are currently connected, and will be remembered so that new peers will get notified as soon as they connect (since the SMPS setting in the beacon may not be the right one). This means that we need to remember the SMPS state currently requested as well as the SMPS state that was configured initially (and advertised in the beacon). The former is bss->req_smps and the latter is sdata->smps_mode. Initially, the AP interface could only be started with SMPS_OFF, which means that sdata->smps_mode was SMPS_OFF always. Later, a nl80211 API was added to be able to start an AP with a different AP mode. That code forgot to update bss->req_smps and because of that, if the AP interface was started with SMPS_DYNAMIC, we had: sdata->smps_mode = SMPS_DYNAMIC bss->req_smps = SMPS_OFF That configuration made mac80211 think it needs to fire off an action frame to any new station connecting to the AP in order to let it know that the actual SMPS configuration is SMPS_OFF. Fix that by properly setting bss->req_smps in ieee80211_start_ap.

2017-06-13mac80211: set bss_info data before configuring the channelJohannes Berg
When mac80211 changes the channel, it also calls into the driver's bss_info_changed() callback, e.g. with BSS_CHANGED_IDLE. The driver may, like iwlwifi does, access more data from bss_info in that case and iwlwifi accesses the basic_rates bitmap, but if changing from a band with more (basic) rates to one with fewer, an out-of-bounds access of the rate array may result. While we can't avoid having invalid data at some point in time, we can avoid having it while we call the driver - so set up all the data before configuring the channel, and then apply it afterwards.

2017-06-12i40e: fix handling of HW ATR evictionJacob Keller
A recent commit to refactor the driver and remove the hw_disabled_flags field accidentally introduced two regressions. First, we overwrote pf->flags which removed various key flags including the MSI-X settings. Additionally, it was intended that we have now two flags, HW_ATR_EVICT_CAPABLE and HW_ATR_EVICT_ENABLED, but this was not done, and we accidentally were mis-using HW_ATR_EVICT_CAPABLE everywhere. This patch adds the missing piece, HW_ATR_EVICT_ENABLED, and safely updates pf->flags instead of overwriting it. Without this patch we will have many problems including disabling MSI-X support, and we'll attempt to use HW ATR eviction on devices which do not support it.

When HSR interface is setup using ip link command, an annoying warning appears with the trace as below:- [ 203.019828] hsr_get_node: Non-HSR frame [ 203.019833] Modules linked in: [ 203.019848] CPU: 0 PID: 158 Comm: sd-resolve Tainted: G W 4.12.0-rc3-00052-g9fa6bf70 #2 [ 203.019853] Hardware name: Generic DRA74X (Flattened Device Tree) [ 203.019869] [<c0110280>] (unwind_backtrace) from [<c010c2f4>] (show_stack+0x10/0x14) [ 203.019880] [<c010c2f4>] (show_stack) from [<c04b9f64>] (dump_stack+0xac/0xe0) [ 203.019894] [<c04b9f64>] (dump_stack) from [<c01374e8>] (__warn+0xd8/0x104) [ 203.019907] [<c01374e8>] (__warn) from [<c0137548>] (warn_slowpath_fmt+0x34/0x44) root@am57xx-evm:~# [ 203.019921] [<c0137548>] (warn_slowpath_fmt) from [<c081126c>] (hsr_get_node+0x148/0x170) [ 203.019932] [<c081126c>] (hsr_get_node) from [<c0814240>] (hsr_forward_skb+0x110/0x7c0) [ 203.019942] [<c0814240>] (hsr_forward_skb) from [<c0811d64>] (hsr_dev_xmit+0x2c/0x34) [ 203.019954] [<c0811d64>] (hsr_dev_xmit) from [<c06c0828>] (dev_hard_start_xmit+0xc4/0x3bc) [ 203.019963] [<c06c0828>] (dev_hard_start_xmit) from [<c06c13d8>] (__dev_queue_xmit+0x7c4/0x98c) [ 203.019974] [<c06c13d8>] (__dev_queue_xmit) from [<c0782f54>] (ip6_finish_output2+0x330/0xc1c) [ 203.019983] [<c0782f54>] (ip6_finish_output2) from [<c0788f0c>] (ip6_output+0x58/0x454) [ 203.019994] [<c0788f0c>] (ip6_output) from [<c07b16cc>] (mld_sendpack+0x420/0x744) As this is an expected path to hsr_get_node() with frame coming from the master interface, add a check to ensure packet is not from the master port and then warn.

2017-06-12cpufreq: conservative: Allow down_threshold to take values from 1 to 10Tomasz Wilczyński
Commit 27ed3cd2ebf4 (cpufreq: conservative: Fix the logic in frequency decrease checking) removed the 10 point substraction when comparing the load against down_threshold but did not remove the related limit for the down_threshold value. As a result, down_threshold lower than 11 is not allowed even though values from 1 to 10 do work correctly too. The comment ("cannot be lower than 11 otherwise freq will not fall") also does not apply after removing the substraction. For this reason, allow down_threshold to take any value from 1 to 99 and fix the related comment.

2017-06-12ACPICA: Tables: Mechanism to handle late stage acpi_get_table() imbalanceLv Zheng
Considering this case: 1. A program opens a sysfs table file 65535 times, it can increase validation_count and first increment cause the table to be mapped: validation_count = 65535 2. AML execution causes "Load" to be executed on the same table, this time it cannot increase validation_count, so validation_count remains: validation_count = 65535 3. The program closes sysfs table file 65535 times, it can decrease validation_count and the last decrement cause the table to be unmapped: validation_count = 0 4. AML code still accessing the loaded table, kernel crash can be observed. To prevent that from happening, add a validation_count threashold. When it is reached, the validation_count can no longer be incremented/decremented to invalidate the table descriptor (means preventing table unmappings) Note that code added in acpi_tb_put_table() is actually a no-op but changes the warning message into a "warn once" one.

2017-06-11compiler, clang: properly override 'inline' for clangLinus Torvalds
Commit abb2ea7dfd82 ("compiler, clang: suppress warning for unused static inline functions") just caused more warnings due to re-defining the 'inline' macro. So undef it before re-defining it, and also add the 'notrace' attribute like the gcc version that this is overriding does. Maybe this makes clang happier.

2017-06-11net: ipmr: Fix some mroute forwarding issues in vrf'sDonald Sharp
This patch fixes two issues: 1) When forwarding on *,G mroutes that are in a vrf, the kernel was dropping information about the actual incoming interface when calling ip_mr_forward from ip_mr_input. This caused ip_mr_forward to send the multicast packet back out the incoming interface. Fix this by modifying ip_mr_forward to be handed the correctly resolved dev. 2) When a unresolved cache entry is created we store the incoming skb on the unresolved cache entry and upon mroute resolution from the user space daemon, we attempt to forward the packet. Again we were not resolving to the correct incoming device for a vrf scenario, before calling ip_mr_forward. Fix this by resolving to the correct interface and calling ip_mr_forward with the result.
