2021-06-22sctp: add probe_interval in sysctl and sock/asoc/transportXin Long1-0/+8
PLPMTUD can be enabled by doing 'sysctl -w net.sctp.probe_interval=n'. 'n' is the interval for PLPMTUD probe timer in milliseconds, and it can't be less than 5000 if it's not 0. All asoc/transport's PLPMTUD in a new socket will be enabled by default.

2021-06-16mm/slub: clarify verification reportingKees Cook1-5/+5
Patch series "Actually fix freelist pointer vs redzoning", v4. This fixes redzoning vs the freelist pointer (both for middle-position and very small caches). Both are "theoretical" fixes, in that I see no evidence of such small-sized caches actually be used in the kernel, but that's no reason to let the bugs continue to exist, especially since people doing local development keep tripping over it. :) This patch (of 3): Instead of repeating "Redzone" and "Poison", clarify which sides of those zones got tripped.

2021-06-11net: dsa: generalize overhead for taggers that use both headers and trailersVladimir Oltean1-10/+11
Some really really weird switches just couldn't decide whether to use a normal or a tail tagger, so they just did both. This creates problems for DSA, because we only have the concept of an 'overhead' which can be applied to the headroom or to the tailroom of the skb (like for example during the central TX reallocation procedure), depending on the value of bool tail_tag, but not to both. We need to generalize DSA to cater for these odd switches by transforming the 'overhead / tail_tag' pair into 'needed_headroom / needed_tailroom'. The DSA master's MTU is increased to account for both. The flow dissector code is modified such that it only calls the DSA adjustment callback if the tagger has a non-zero header length. Taggers are trivially modified to declare either needed_headroom or needed_tailroom, based on the tail_tag value that they currently declare.

2021-06-10net/mlx5: Bridge, support pvid and untagged vlan configurationsVlad Buslov1-0/+8
Implement support for pushing vlan header into untagged packet on ingress of port that has pvid configured and support for popping vlan on egress of port that has the matching vlan configured as untagged. To support such configurations packet reformat contexts of {INSERT|REMOVE}_HEADER types are created per such vlan and saved to struct mlx5_esw_bridge_vlan which allows all FDB entries on particular vlan to share single packet reformat instance. When initializing FDB entries with pvid or untagged vlan type set its mlx5_flow_act->pkt_reformat action accordingly. Flush all flows when removing vlan from port. This is necessary because even though software bridge removes all FDB entries before removing their vlan, mlx5 bridge implementation deletes their corresponding flow entries from hardware in asynchronous workqueue task, which will cause firmware error if vlan packet reformat context is deleted before all flows that point to it.

2021-06-10net/mlx5: Bridge, handle FDB eventsVlad Buslov1-0/+15
Hardware supported by mlx5 driver doesn't provide learning and requires the driver to emulate all switch-like behavior in software. As such, all packets by default go through miss path, appear on representor and get to software bridge, if it is the upper device of the representor. This causes bridge to process packet in software, learn the MAC address to FDB and send SWITCHDEV_FDB_ADD_TO_DEVICE event to all subscribers. In order to offload FDB entries in mlx5, register switchdev notifier callback and implement support for both 'added_by_user' and dynamic FDB entry SWITCHDEV_FDB_ADD_TO_DEVICE events asynchronously using new mlx5_esw_bridge_offloads->wq ordered workqueue. In workqueue callback offload the ingress rule (matching FDB entry MAC as packet source MAC) and egress table rule (matching FDB entry MAC as destination MAC). For ingress table rule also match source vport to ensure that only traffic coming from expected bridge port is matched by offloaded rule. Save all the relevant FDB entry data in struct mlx5_esw_bridge_fdb_entry instance and insert the instance in new mlx5_esw_bridge->fdb_list list (for traversing all entries by software ageing implementation in following patch) and in new mlx5_esw_bridge->fdb_ht hash table for fast retrieval. Notify the bridge that FDB entry has been offloaded by sending SWITCHDEV_FDB_OFFLOADED notification. Delete FDB entry on reception of SWITCHDEV_FDB_DEL_TO_DEVICE event.

There are 4 variations of the SJA1110 switch which have a different set of MII protocols supported per port. Document the compatible strings. Also, the SJA1110 optionally supports 2 internal MDIO buses for 2 different types of Ethernet PHYs. Document a container node called "mdios" which has 2 subnodes "mdio@0" and "mdio@1", identifiable via compatible string, under which the driver finds the internal PHYs.

2021-06-08KVM: X86: MMU: Use the correct inherited permissions to get shadow pageLai Jiangshan1-2/+2
When computing the access permissions of a shadow page, use the effective permissions of the walk up to that point, i.e. the logic AND of its parents' permissions. Two guest PxE entries that point at the same table gfn need to be shadowed with different shadow pages if their parents' permissions are different. KVM currently uses the effective permissions of the last non-leaf entry for all non-leaf entries. Because all non-leaf SPTEs have full ("uwx") permissions, and the effective permissions are recorded only in role.access and merged into the leaves, this can lead to incorrect reuse of a shadow page and eventually to a missing guest protection page fault. For example, here is a shared pagetable: pgd[] pud[] pmd[] virtual address pointers /->pmd1(u--)->pte1(uw-)->page1 <- ptr1 (u--) /->pud1(uw-)--->pmd2(uw-)->pte2(uw-)->page2 <- ptr2 (uw-) pgd-| (shared pmd[] as above) \->pud2(u--)--->pmd1(u--)->pte1(uw-)->page1 <- ptr3 (u--) \->pmd2(uw-)->pte2(uw-)->page2 <- ptr4 (u--) pud1 and pud2 point to the same pmd table, so: - ptr1 and ptr3 points to the same page. - ptr2 and ptr4 points to the same page. (pud1 and pud2 here are pud entries, while pmd1 and pmd2 here are pmd entries) - First, the guest reads from ptr1 first and KVM prepares a shadow page table with role.access=u--, from ptr1's pud1 and ptr1's pmd1. "u--" comes from the effective permissions of pgd, pud1 and pmd1, which are stored in pt->access. "u--" is used also to get the pagetable for pud1, instead of "uw-". - Then the guest writes to ptr2 and KVM reuses pud1 which is present. The hypervisor set up a shadow page for ptr2 with pt->access is "uw-" even though the pud1 pmd (because of the incorrect argument to kvm_mmu_get_page in the previous step) has role.access="u--". - Then the guest reads from ptr3. The hypervisor reuses pud1's shadow pmd for pud2, because both use "u--" for their permissions. Thus, the shadow pmd already includes entries for both pmd1 and pmd2. - At last, the guest writes to ptr4. This causes no vmexit or pagefault, because pud1's shadow page structures included an "uw-" page even though its role.access was "u--". Any kind of shared pagetable might have the similar problem when in virtual machine without TDP enabled if the permissions are different from different ancestors. In order to fix the problem, we change pt->access to be an array, and any access in it will not include permissions ANDed from child ptes. The test code is: https://lore.kernel.org/kvm/20210603050537.19605-1-jiangshanlai@gmail.com/ Remember to test it with TDP disabled. The problem had existed long before the commit 41074d07c78b ("KVM: MMU: Fix inherited permissions for emulated guest pte updates"), and it is hard to find which is the culprit. So there is no fixes tag here.

2021-06-07net: dsa: sja1105: determine PHY/MAC role from PHY interface typeVladimir Oltean1-36/+1
Now that both RevMII as well as RevRMII exist, we can deprecate the sja1105,role-mac and sja1105,role-phy properties and simply let the user select that a port operates in MII PHY role by using phy-mode = "rev-mii"; or in RMII PHY role by using phy-mode = "rev-rmii"; There are no fixed-link MII or RMII properties in mainline device trees, and the setup itself is fairly uncommon, so there shouldn't be risks of breaking compatibility.

2021-06-07net: phy: introduce PHY_INTERFACE_MODE_REVRMIIVladimir Oltean1-0/+1
The "reverse RMII" protocol name is a personal invention, derived from "reverse MII". Just like MII, RMII is an asymmetric protocol in that a PHY behaves differently than a MAC. In the case of RMII, for example: - the 50 MHz clock signals are either driven by the MAC or by an external oscillator (but never by the PHY). - the PHY can transmit extra in-band control symbols via RXD[1:0] which the MAC is supposed to understand, but a PHY isn't. The "reverse MII" protocol is not standardized either, except for this web document: https://www.eetimes.com/reverse-media-independent-interface-revmii-block-architecture/# In short, it means that the Ethernet controller speaks the 4-bit data parallel protocol from the perspective of a PHY (it acts like a PHY). This might mean that it implements clause 22 compatible registers, although that is optional - the important bit is that its pins can be connected to an MII MAC and it will 'just work'. In this discussion thread: https://lore.kernel.org/netdev/20210201214515.cx6ivvme2tlquge2@skbuf/ we agreed that it would be an abuse of terms to use the "RevMII" name for anything than the 4-bit parallel MII protocol. But since all the same concepts can be applied to the 2-bit Reduced MII protocol as well, here we are introducing a "Reverse RMII" protocol. This means: "behave like an RMII PHY".
