The SoC R40 AHCI controller need a PHY regulator to work. But since the PHY is embedded in the controller, we cannot do a DT node for it, since phy-supply works only in node with a PHY compatible. So this patch adds a way to add an optional phy-supply regulator on AHCI controller node.

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.

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. Specifically the current behavior is: mce: Uncorrected hardware memory error in user-access at af34214200 {1}[Hardware Error]: It has been corrected by h/w and requires no further action mce: [Hardware Error]: Machine check events logged {1}[Hardware Error]: event severity: corrected Memory failure: 0xaf34214: reserved kernel page still referenced by 1 users [..] Memory failure: 0xaf34214: recovery action for reserved kernel page: Failed mce: Memory error not recovered <reboot> ...and with these changes: Injecting memory failure for pfn 0x20cb00 at process virtual address 0x7f763dd00000 Memory failure: 0x20cb00: Killing dax-pmd:5421 due to hardware memory corruption Memory failure: 0x20cb00: recovery action for dax page: Recovered Given all the cross dependencies I propose taking this through nvdimm.git with acks from Naoya, x86/core, x86/RAS, and of course dax folks" * tag 'libnvdimm-for-4.19_dax-memory-failure' of gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm: libnvdimm, pmem: Restore page attributes when clearing errors x86/memory_failure: Introduce {set, clear}_mce_nospec() x86/mm/pat: Prepare {reserve, free}_memtype() for "decoy" addresses mm, memory_failure: Teach memory_failure() about dev_pagemap pages filesystem-dax: Introduce dax_lock_mapping_entry() mm, memory_failure: Collect mapping size in collect_procs() mm, madvise_inject_error: Let memory_failure() optionally take a page reference mm, dev_pagemap: Do not clear ->mapping on final put mm, madvise_inject_error: Disable MADV_SOFT_OFFLINE for ZONE_DEVICE pages filesystem-dax: Set page->index device-dax: Set page->index device-dax: Enable page_mapping() device-dax: Convert to vmf_insert_mixed and vm_fault_t

qlge_fix_features() is not supposed to modify hardware or driver state, rather it is supposed to only fix requested fetures bits. Currently qlge_fix_features() also goes for interface down and up unnecessarily if there is not even any change in features set. This patch changes/fixes following - 1) Move reload of interface or device re-config from qlge_fix_features() to qlge_set_features(). 2) Reload of interface in qlge_set_features() only if relevant feature bit (NETIF_F_HW_VLAN_CTAG_RX) is changed. 3) Get rid of qlge_fix_features() since driver is not really required to fix any features bit.

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.

commit 739de9a1 ("net: macb: Reorganize macb_mii bringup") broke initializing macb on the EVB-KSZ9477 eval board. There, of_mdiobus_register was called even for the fixed-link representing the RGMII-link to the switch with the result that the driver attempts to enumerate PHYs on a non-existent MDIO bus: libphy: MACB_mii_bus: probed mdio_bus f0028000.ethernet-ffffffff: fixed-link has invalid PHY address mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 0 [snip] mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 31 The "MDIO" bus registration succeeds regardless, having claimed the reset GPIO, and calling of_phy_register_fixed_link later on fails because it tries to claim the same GPIO: macb f0028000.ethernet: broken fixed-link specification Fix this by registering the fixed-link before calling mdiobus_register.

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.

At the point where r is being checked for different values, r is always going to be equal to 2 as the previous if statements jump to end or end1 if r is not 2. Hence the assignment to err can be simplified to just err an assignment without any checks on the value or r.

Thanks for your work in this area. I still remember the first linux storage summit we did in Vancouver 2001, Tejun was invited to talk about his libata error handling work. Before that, it was basically a crap shoot if we recovered properly or not... A lot of water has flown under the bridge since then! Here's an "official" patch. Linus, can you apply it?

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: David S.
