1) The maximum device nodes is a global value and shared by the whole device. Add element AQ command would fail if there is no space to add new nodes so the check for max nodes isn't required. So remove ice_sched_get_num_nodes_per_layer and ice_sched_val_max_nodes. 2) In ice_sched_add_elems, set default node's CIR/EIR bandwidth weight. 3) Fix default scheduler topology buffer size as the firmware expects a 4KB buffer at all times, and will error out if one of any other size is provided. 4) In the latest spec, max children per node per layer is replaced by max sibling group size. Now it provides the max children of the below layer node, not the current layer node. 5) Fix some newline/whitespace issues for consistency. Signed-off-by:

Via u32_change(), TCA_U32_SEL has an unspecified type in the netlink policy, so max length isn't enforced, only minimum. This means nkeys (from userspace) was being trusted without checking the actual size of nla_len(), which could lead to a memory over-read, and ultimately an exposure via a call to u32_dump(). Reachability is CAP_NET_ADMIN within a namespace. Reported-by:

Merge tag 'libnvdimm-for-4.19_dax-memory-failure' of gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm memory-failure update from Dave Jiang: "As it stands, memory_failure() gets thoroughly confused by dev_pagemap backed mappings. The recovery code has specific enabling for several possible page states and needs new enabling to handle poison in dax mappings. In order to support reliable reverse mapping of user space addresses: 1/ Add new locking in the memory_failure() rmap path to prevent races that would typically be handled by the page lock. 2/ Since dev_pagemap pages are hidden from the page allocator and the "compound page" accounting machinery, add a mechanism to determine the size of the mapping that encompasses a given poisoned pfn. 3/ Given pmem errors can be repaired, change the speculatively accessed poison protection, mce_unmap_kpfn(), to be reversible and otherwise allow ongoing access from the kernel. A side effect of this enabling is that MADV_HWPOISON becomes usable for dax mappings, however the primary motivation is to allow the system to survive userspace consumption of hardware-poison via dax.

macb_reset_hw() is called from macb_close() and indirectly from macb_open(). macb_reset_hw() zeroes the NCR register, including the MPE (Management Port Enable) bit. This will prevent accessing any other PHYs for other Ethernet MACs on the MDIO bus, which remains registered at macb_reset_hw() time, until macb_init_hw() is called from macb_open() which sets the MPE bit again. I.e. currently the MDIO bus has a short disruption at open time and is disabled at close time until the interface is opened again. Fix that by only touching the RE and TE bits when enabling and disabling RX/TX. v2: Make macb_init_hw() NCR write a single statement. Fixes: 6c36a707 ("macb: Use generic PHY layer") Signed-off-by:

When a bridge device is removed, the VLANs are flushed from each configured port. This causes the ports to decrement the reference count on the associated FIDs (filtering identifier). If the reference count of a FID is 1 and it has a RIF (router interface), then this RIF is destroyed. However, if no port is member in the VLAN for which a RIF exists, then the RIF will continue to exist after the removal of the bridge. To reproduce: # ip link add name br0 type bridge vlan_filtering 1 # ip link set dev swp1 master br0 # ip link add link br0 name br0.10 type vlan id 10 # ip address add 192.0.2.0/24 dev br0.10 # ip link del dev br0 The RIF associated with br0.10 continues to exist. Fix this by iterating over all the bridge device uppers when it is destroyed and take care of destroying their RIFs.

This is not normally noticeable, but repeated forks are unnecessarily expensive because they repeatedly dirty the parent page tables during the page table copy operation. It's trivial to just avoid write protecting the page table entry if it was already not writable. This patch was inspired by https://bugzilla.kernel.org/show_bug.cgi?id=200447 which points to an ancient "waste time re-doing fork" issue in the presence of lots of signals. That bug was fixed by Eric Biederman's signal handling series culminating in commit c3ad2c3b ("signal: Don't restart fork when signals come in"), but the unnecessary work for repeated forks is still work just fixing, particularly since the fix is trivial.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2018-08-24 This series contains fixes to e1000, igb, ixgb, ixgbe and i40e. YueHaibing from Huawei provides a change to use dma_zalloc_coherent() instead of calls to allocator followed by a memset for ixgb. Bo Chen provides a couple of fixes for e1000, first by adding a check to prevent a NULL pointer dereference. The second change is to clean up a possible resource leak on old transmit and receive rings when the device is not up. Jesus fixes an issue in the usage of an advanced transmit context descriptor for retrieving the timestamp of a packet for AF_PACKET if the IGB_TX_FLAGS_VLAN is not set in igb. Jia-Ju Bai provides several patches which replace GFP_ATOMIC with GFP_KERNEL, when using kzalloc() and kcalloc() which is not necessary. Also found an instance of mdelay() call which could be replaced with msleep(). Tony fixes ixgbe to allow MTU changes with XDP, by adding checks to ensure only supported values and return -EINVAL for when it is not supported. Sebastian fixed an issue that was not clearing VF mailbox memory and ensure queues are re-enabled correctly. Martyna fixes a transmit timeout when DCB is configured when bringing up an interface. Jake fixes a previous commit which accidentally reversed the check of the data pointer, so we can accurately count the size of the stats. ==================== Signed-off-by:

Pull powerpc fixes from Michael Ellerman: - An implementation for the newly added hv_ops->flush() for the OPAL hvc console driver backends, I forgot to apply this after merging the hvc driver changes before the merge window. - Enable all PCI bridges at boot on powernv, to avoid races when multiple children of a bridge try to enable it simultaneously. This is a workaround until the PCI core can be enhanced to fix the races. - A fix to query PowerVM for the correct system topology at boot before initialising sched domains, seen in some configurations to cause broken scheduling etc. - A fix for pte_access_permitted() on "nohash" platforms. - Two commits to fix SIGBUS when using remap_pfn_range() seen on Power9 due to a workaround when using the nest MMU (GPUs, accelerators). - Another fix to the VFIO code used by KVM, the previous fix had some bugs which caused guests to not start in some configurations. - A handful of other minor fixes. Thanks to: Aneesh Kumar K.V, Benjamin Herrenschmidt, Christophe Leroy, Hari Bathini, Luke Dashjr, Mahesh Salgaonkar, Nicholas Piggin, Paul Mackerras, Srikar Dronamraju. * tag 'powerpc-4.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/mce: Fix SLB rebolting during MCE recovery path.
