Locking ppp_mutex must be done before dereferencing file->private_data, otherwise it could be modified before ppp_unattached_ioctl() takes the lock. This could lead ppp_unattached_ioctl() to override ->private_data, thus leaking reference to the ppp_file previously pointed to. v2: lock all ppp_ioctl() instead of just checking private_data in ppp_unattached_ioctl(), to avoid ambiguous behaviour.

This patch adds the emac device node for rk3036 SoCs. We need to let mac clock under the DPLL which is able to provide the accurate 50MHz what mac_ref need, since that will cause some unstable things if the cpufreq is working. Signed-off-by:

The emac needs constant and very specific rate but the possible PLL-sources are very limited, so we expect the PLL source to be set manually on per board and don't want it to get changed in an automatic way later. So add the necessary clock-id and disable reparenting on set_rate calls. Signed-off-by:

This patch adds the following property for arc_emac. 1) phy-reset-gpios: The phy-reset-gpio is an optional property for arc emac device tree boot. Change the binding document to match the driver code. 2) phy-reset-duration: Different boards may require different phy reset duration. Add property phy-reset-duration for device tree probe, so that the boards that need a longer reset duration can specify it in their device tree. Anyway, we can add the above property for arc emac.

In order to deal with that, stop calling netif_start_queue() from there, so that it can be called only when the device is fully opened and sh_eth_dev_init() only deals with the hardware initialization, symmetrically to sh_eth_dev_exit()...

When driver has hit a parity event, HW can no longer write to host memory. As a result, Tx completions cannot be written to the host SB memory, and waiting for Tx completions eventually timeout. As driver is willing to delay as much as 1-2 seconds per Tx queue for its draining and this delay is sequential, the time to recover might greatly lengthen needlessly in case the recovery is done under multi-connection traffic.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS/OVS updates for net-next The following patchset contains Netfilter/IPVS fixes and OVS NAT support, more specifically this batch is composed of: 1) Fix a crash in ipset when performing a parallel flush/dump with set:list type, from Jozsef Kadlecsik. 2) Make sure NFACCT_FILTER_* netlink attributes are in place before accessing them, from Phil Turnbull. 3) Check return error code from ip_vs_fill_iph_skb_off() in IPVS SIP helper, from Arnd Bergmann. 4) Add workaround to IPVS to reschedule existing connections to new destination server by dropping the packet and wait for retransmission of TCP syn packet, from Julian Anastasov. 5) Allow connection rescheduling in IPVS when in CLOSE state, also from Julian. 6) Fix wrong offset of SIP Call-ID in IPVS helper, from Marco Angaroni. 7) Validate IPSET_ATTR_ETHER netlink attribute length, from Jozsef. 8) Check match/targetinfo netlink attribute size in nft_compat, patch from Florian Westphal. 9) Check for integer overflow on 32-bit systems in x_tables, from Florian Westphal. Several patches from Jarno Rajahalme to prepare the introduction of NAT support to OVS based on the Netfilter infrastructure: 10) Schedule IP_CT_NEW_REPLY definition for removal in nf_conntrack_common.h. 11) Simplify checksumming recalculation in nf_nat. 12) Add comments to the openvswitch conntrack code, from Jarno. 13) Update the CT state key only after successful nf_conntrack_in() invocation. 14) Find existing conntrack entry after upcall. 15) Handle NF_REPEAT case due to templates in nf_conntrack_in(). 16) Call the conntrack helper functions once the conntrack has been confirmed. 17) And finally, add the NAT interface to OVS. The batch closes with: 18) Cleanup to use spin_unlock_wait() instead of spin_lock()/spin_unlock(), from Nicholas Mc Guire. ==================== Signed-off-by: -

The smc91x driver defines a macro that compares its argument to itself, apparently to get a true result while using its argument to avoid a warning about unused local variables. Unfortunately, this triggers a warning with gcc-6, as the comparison is obviously useless: drivers/net/ethernet/smsc/smc91x.c: In function 'smc_hardware_send_pkt': drivers/net/ethernet/smsc/smc91x.c:563:14: error: self-comparison always evaluates to true [-Werror=tautological-compare] if (!smc_special_trylock(&lp->lock, flags)) { This replaces the macro with another one that behaves similarly, with a cast to (void) to ensure the argument is used, and using a literal 'true' as its value.

Extend OVS conntrack interface to cover NAT. New nested OVS_CT_ATTR_NAT attribute may be used to include NAT with a CT action. A bare OVS_CT_ATTR_NAT only mangles existing and expected connections. If OVS_NAT_ATTR_SRC or OVS_NAT_ATTR_DST is included within the nested attributes, new (non-committed/non-confirmed) connections are mangled according to the rest of the nested attributes. The corresponding OVS userspace patch series includes test cases (in tests/system-traffic.at) that also serve as example uses.

Add a new function ovs_ct_find_existing() to find an existing conntrack entry for which this packet was already applied to. This is only to be called when there is evidence that the packet was already tracked and committed, but we lost the ct reference due to an userspace upcall. ovs_ct_find_existing() is called from skb_nfct_cached(), which can now hide the fact that the ct reference may have been lost due to an upcall. This allows ovs_ct_commit() to be simplified. This patch is needed by later "openvswitch: Interface with NAT" patch, as we need to be able to pass the packet through NAT using the original ct reference also after the reference is lost after an upcall.

Gregory CLEMENT says: ==================== Few mvneta fixes In this second version I split the last patch in two parts as requested. For the record the initial cover letter was: "here is a patch set of few fixes. Without the first one, a kernel configured with debug features ended to hang when the driver is built as a module and is removed. This is quite is annoying for debugging! The second patch fix a forgotten flag at the initial submission of the driver. The third patch is only really a cosmetic one so I have no problem to not apply it for 4.5 and wait for 4.6. I really would like to see the first one applied for 4.5 and for the second I let you judge if it something needed for now or that should wait the next release." ==================== Signed-off-by: -

In the previous patch, the spinlock was not initialized. While it didn't cause any trouble yet it could be a problem to use it uninitialized. The most annoying part was the critical section protected by the spinlock in mvneta_stop(). Some of the functions could sleep as pointed when activated CONFIG_DEBUG_ATOMIC_SLEEP. Actually, in mvneta_stop() we only need to protect the is_stopped flagged, indeed the code of the notifier for CPU online is protected by the same spinlock, so when we get the lock, the notifer work is done.

Zefir Kurtisi reported kernel panic with an openwrt specific patch. However, it turns out that mainline has a similar bug waiting to happen. Once NF_HOOK() returns the skb is in undefined state and must not be used. Moreover, the okfn must consume the skb to support async processing (NF_QUEUE). Current okfn in this spot doesn't consume it and caller assumes that NF_HOOK return value tells us if skb was freed or not, but thats wrong. It "works" because no in-tree user registers a NFPROTO_BRIDGE hook at LOCAL_IN that returns STOLEN or NF_QUEUE verdicts. Once we add NF_QUEUE support for nftables bridge this will break -- NF_QUEUE holds the skb for async processing, caller will erronoulsy return RX_HANDLER_PASS and on reinject netfilter will access free'd skb. Fix this by pushing skb up the stack in the okfn instead. NB: It also seems dubious to use LOCAL_IN while bypassing PRE_ROUTING completely in this case but this is how its been forever so it seems preferable to not change this.
