net: wan: Delete the DLCI / SDLA drivers
The DLCI driver (dlci.c) implements the Frame Relay protocol. However,
we already have another newer and better implementation of Frame Relay
provided by the HDLC_FR driver (hdlc_fr.c).
The DLCI driver's implementation of Frame Relay is used by only one
hardware driver in the kernel - the SDLA driver (sdla.c).
The SDLA driver provides Frame Relay support for the Sangoma S50x devices.
However, the vendor provides their own driver (along with their own
multi-WAN-protocol implementations including Frame Relay), called WANPIPE.
I believe most users of the hardware would use the vendor-provided WANPIPE
driver instead.
(The WANPIPE driver was even once in the kernel, but was deleted in

Daniel Borkmann says: ==================== pull-request: bpf-next 2020-11-14 1) Add BTF generation for kernel modules and extend BTF infra in kernel e.g. support for split BTF loading and validation, from Andrii Nakryiko. 2) Support for pointers beyond pkt_end to recognize LLVM generated patterns on inlined branch conditions, from Alexei Starovoitov. 3) Implements bpf_local_storage for task_struct for BPF LSM, from KP Singh. 4) Enable FENTRY/FEXIT/RAW_TP tracing program to use the bpf_sk_storage infra, from Martin KaFai Lau. 5) Add XDP bulk APIs that introduce a defer/flush mechanism to optimize the XDP_REDIRECT path, from Lorenzo Bianconi. 6) Fix a potential (although rather theoretical) deadlock of hashtab in NMI context, from Song Liu. 7) Fixes for cross and out-of-tree build of bpftool and runqslower allowing build for different target archs on same source tree, from Jean-Philippe Brucker. 8) Fix error path in htab_map_alloc() triggered from syzbot, from Eric Dumazet. 9) Move functionality from test_tcpbpf_user into the test_progs framework so it can run in BPF CI, from Alexander Duyck. 10) Lift hashtab key_size limit to be larger than MAX_BPF_STACK, from Florian Lehner. Note that for the fix from Song we have seen a sparse report on context imbalance which requires changes in sparse itself for proper annotation detection where this is currently being discussed on linux-sparse among developers [0]. Once we have more clarification/guidance after their fix, Song will follow-up.

bpf: Assign ID to vmlinux BTF and return extra info for BTF in GET_OBJ_INFO
Allocate ID for vmlinux BTF. This makes it visible when iterating over all BTF
objects in the system. To allow distinguishing vmlinux BTF (and later kernel
module BTF) from user-provided BTFs, expose extra kernel_btf flag, as well as
BTF name ("vmlinux" for vmlinux BTF, will equal to module's name for module
BTF). We might want to later allow specifying BTF name for user-provided BTFs
as well, if that makes sense. But currently this is reserved only for
in-kernel BTFs.
Having in-kernel BTFs exposed IDs will allow to extend BPF APIs that require
in-kernel BTF type with ability to specify BTF types from kernel modules, not
just vmlinux BTF. This will be implemented in a follow up patch set for
fentry/fexit/fmod_ret/lsm/etc.

net/packet: make packet_fanout.arr size configurable up to 64K
One use case of PACKET_FANOUT is lockless reception with one socket per CPU. 256 is a practical limit on increasingly many machines. Increase PACKET_FANOUT_MAX to 64K. Expand setsockopt PACKET_FANOUT to take an extra argument max_num_members. Also explicitly define a fanout_args struct, instead of implicitly casting to an integer. This documents the API and simplifies the control flow. If max_num_members is not specified or is set to 0, then 256 is used, same as before.

net: udp: introduce UDP_MIB_MEMERRORS for udp_mem
When udp_memory_allocated is at the limit, __udp_enqueue_schedule_skb
will return a -ENOBUFS, and skb will be dropped in __udp_queue_rcv_skb
without any counters being done. It's hard to find out what happened
once this happen.
So we introduce a UDP_MIB_MEMERRORS to do this job. Well, this change

rtnetlink: Add RTNH_F_TRAP flag
The flag indicates to user space that the nexthop is not programmed to forward packets in hardware, but rather to trap them to the CPU. This is needed, for example, when the MAC of the nexthop neighbour is not resolved and packets should reach the CPU to trigger neighbour resolution. The flag will be used in subsequent patches by netdevsim to test nexthop objects programming to device drivers and in the future by mlxsw as well.

The currently available bpf_get_current_task returns an unsigned integer which can be used along with BPF_CORE_READ to read data from the task_struct but still cannot be used as an input argument to a helper that accepts an ARG_PTR_TO_BTF_ID of type task_struct. In order to implement this helper a new return type, RET_PTR_TO_BTF_ID, is added. This is similar to RET_PTR_TO_BTF_ID_OR_NULL but does not require checking the nullness of returned pointer.

bpf: Implement task local storage
Similar to bpf_local_storage for sockets and inodes add local storage for task_struct. The life-cycle of storage is managed with the life-cycle of the task_struct. i.e. the storage is destroyed along with the owning task with a callback to the bpf_task_storage_free from the task_free LSM hook. The BPF LSM allocates an __rcu pointer to the bpf_local_storage in the security blob which are now stackable and can co-exist with other LSMs. The userspace map operations can be done by using a pid fd as a key passed to the lookup, update and delete operations.

cfg80211: Add support to configure SAE PWE value to drivers
Add support to configure SAE PWE preference from userspace to drivers in both AP and STA modes. This is needed for cases where the driver takes care of Authentication frame processing (SME in the driver) so that correct enforcement of the acceptable PWE derivation mechanism can be performed. The userspace applications can pass the sae_pwe value using the NL80211_ATTR_SAE_PWE attribute in the NL80211_CMD_CONNECT and NL80211_CMD_START_AP commands to the driver. This allows selection between the hunting-and-pecking loop and hash-to-element options for PWE derivation. For backwards compatibility, this new attribute is optional and if not included, the driver is notified of the value being unspecified.

Char/Misc fixes/removals for 5.10-rc2
Here's some small fixes for 5.10-rc2 and a big driver removal. The fixes are for some reported issues in the interconnect and coresight drivers, nothing major. The "big" driver removal is the MIC drivers have been asked to be removed as the hardware never shipped and Intel no longer wants to maintain something that no one can use. This is welcomed by many as the DMA usage of these drivers was "interesting" and the security people were starting to question some issues that were starting to be found in the codebase. Note, one of the subsystems for this driver, the "VOP" code, will probably come back in future kernel versions as it was looking to potentially solve some PCIe virtualization issues that a number of other vendors were wanting to solve. But as-is, this codebase didn't work for anyone else so no actual functionality is being removed. All of these have been in linux-next with no reported issues.

net: bridge: mcast: add support for raw L2 multicast groups
Extend the bridge multicast control and data path to configure routes for L2 (non-IP) multicast groups. The uapi struct br_mdb_entry union u is extended with another variant, mac_addr, which does not change the structure size, and which is valid when the proto field is zero. To be compatible with the forwarding code that is already in place, which acts as an IGMP/MLD snooping bridge with querier capabilities, we need to declare that for L2 MDB entries (for which there exists no such thing as IGMP/MLD snooping/querying), that there is always a querier. Otherwise, these entries would be flooded to all bridge ports and not just to those that are members of the L2 multicast group. Needless to say, only permanent L2 multicast groups can be installed on a bridge port.

sctp: add SCTP_REMOTE_UDP_ENCAPS_PORT sockopt
This patch is to implement:
rfc6951#section-6.1: Get or Set the Remote UDP Encapsulation Port Number
with the param of the struct:
struct sctp_udpencaps {
sctp_assoc_t sue_assoc_id;
struct sockaddr_storage sue_address;
uint16_t sue_port;
};
the encap_port of sock, assoc or transport can be changed by users,
which also means it allows the different transports of the same asoc
to have different encap_port value.
v1->v2:
- no change.
v2->v3:
- fix the endian warning when setting values between encap_port and
sue_port.

bridge: cfm: Kernel space implementation of CFM. MEP create/delete.
This is the first commit of the implementation of the CFM protocol
according to 802.1Q section 12.14.
It contains MEP instance create, delete and configuration.
Connectivity Fault Management (CFM) comprises capabilities for
detecting, verifying, and isolating connectivity failures in
Virtual Bridged Networks. These capabilities can be used in
networks operated by multiple independent organizations, each
with restricted management access to each others equipment.
CFM functions are partitioned as follows:
- Path discovery
- Fault detection
- Fault verification and isolation
- Fault notification
- Fault recovery
Interface consists of these functions:
br_cfm_mep_create()
br_cfm_mep_delete()
br_cfm_mep_config_set()
br_cfm_cc_config_set()
br_cfm_cc_peer_mep_add()
br_cfm_cc_peer_mep_remove()
A MEP instance is created by br_cfm_mep_create()
-It is the Maintenance association End Point
described in 802.1Q section 19.2.
-It is created on a specific level (1-7) and is assuring
that no CFM frames are passing through this MEP on lower levels.
-It initiates and validates CFM frames on its level.
-It can only exist on a port that is related to a bridge.
-Attributes given cannot be changed until the instance is
deleted.
A MEP instance can be deleted by br_cfm_mep_delete().
A created MEP instance has attributes that can be

wimax: move out to staging
There are no known users of this driver as of October 2020, and it will be removed unless someone turns out to still need it in future releases. According to https://en.wikipedia.org/wiki/List_of_WiMAX_networks, there have been many public wimax networks, but it appears that many of these have migrated to LTE or discontinued their service altogether. As most PCs and phones lack WiMAX hardware support, the remaining networks tend to use standalone routers. These almost certainly run Linux, but not a modern kernel or the mainline wimax driver stack. NetworkManager appears to have dropped userspace support in 2015 https://bugzilla.gnome.org/show_bug.cgi?id=747846, the www.linuxwimax.org site had already shut down earlier. WiMax is apparently still being deployed on airport campus networks ("AeroMACS"), but in a frequency band that was not supported by the old Intel 2400m (used in Sandy Bridge laptops and earlier), which is the only driver using the kernel's wimax stack. Move all files into drivers/staging/wimax, including the uapi header files and documentation, to make it easier to remove it when it gets to that. Only minimal changes are made to the source files, in order to make it possible to port patches across the move. Also remove the MAINTAINERS entry that refers to a broken mailing list and website.

Fixes for 5.10-rc1 from the networking tree:
Cross-tree/merge window issues:
- rtl8150: don't incorrectly assign random MAC addresses; fix late
in the 5.9 cycle started depending on a return code from
a function which changed with the 5.10 PR from the usb subsystem
Current release - regressions:
- Revert "virtio-net: ethtool configurable RXCSUM", it was causing
crashes at probe when control vq was not negotiated/available
Previous releases - regressions:
- ixgbe: fix probing of multi-port 10 Gigabit Intel NICs with an MDIO
bus, only first device would be probed correctly
- nexthop: Fix performance regression in nexthop deletion by
effectively switching from recently added synchronize_rcu()
to synchronize_rcu_expedited()
- netsec: ignore 'phy-mode' device property on ACPI systems;
the property is not populated correctly by the firmware,
but firmware configures the PHY so just keep boot settings
Previous releases - always broken:
- tcp: fix to update snd_wl1 in bulk receiver fast path, addressing
bulk transfers getting "stuck"
- icmp: randomize the global rate limiter to prevent attackers from
getting useful signal
- r8169: fix operation under forced interrupt threading, make the
driver always use hard irqs, even on RT, given the handler is
light and only wants to schedule napi (and do so through
a _irqoff() variant, preferably)
- bpf: Enforce pointer id generation for all may-be-null register
type to avoid pointers erroneously getting marked as null-checked
- tipc: re-configure queue limit for broadcast link
- net/sched: act_tunnel_key: fix OOB write in case of IPv6 ERSPAN
tunnels
- fix various issues in chelsio inline tls driver
Misc:
- bpf: improve just-added bpf_redirect_neigh() helper api to support
supplying nexthop by the caller - in case BPF program has already
done a lookup we can avoid doing another one
- remove unnecessary break statements
- make MCTCP not select IPV6, but rather depend on it

vhost: vdpa: report iova range
This patch introduces a new ioctl for vhost-vdpa device that can report the iova range by the device. For device that implements get_iova_range() method, we fetch it from the vDPA device. If device doesn't implement get_iova_range() but depends on platform IOMMU, we will query via DOMAIN_ATTR_GEOMETRY, otherwise [0, ULLONG_MAX] is assumed. For safety, this patch also rules out the map request which is not in the valid range.

bpf: Fix bpf_redirect_neigh helper api to support supplying nexthop
Based on the discussion in [0], update the bpf_redirect_neigh() helper to accept an optional parameter specifying the nexthop information. This makes it possible to combine bpf_fib_lookup() and bpf_redirect_neigh() without incurring a duplicate FIB lookup - since the FIB lookup helper will return the nexthop information even if no neighbour is present, this can simply be passed on to bpf_redirect_neigh() if bpf_fib_lookup() returns BPF_FIB_LKUP_RET_NO_NEIGH. Thus fix & extend it before helper API is frozen.

kvm: x86: only provide PV features if enabled in guest's CPUID
KVM unconditionally provides PV features to the guest, regardless of the configured CPUID. An unwitting guest that doesn't check KVM_CPUID_FEATURES before use could access paravirt features that userspace did not intend to provide. Fix this by checking the guest's CPUID before performing any paravirtual operations. Introduce a capability, KVM_CAP_ENFORCE_PV_FEATURE_CPUID, to gate the aforementioned enforcement. Migrating a VM from a host w/o this patch to a host with this patch could silently change the ABI exposed to the guest, warranting that we default to the old behavior and opt-in for the new one.

This can improve I/O performance for various workloads, as well as reducing the memory requirement by eliminating double caching. Thanks to Vivek Goyal for doing most of the work on this. - Allow automatic submounting inside virtiofs. This allows unique st_dev/ st_ino values to be assigned inside the guest to files residing on different filesystems on the host. Thanks to Max Reitz for the patches. - Fix an old use after free bug found by Pradeep P V K. * tag 'fuse-update-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse: (25 commits) virtiofs: calculate number of scatter-gather elements accurately fuse: connection remove fix fuse: implement crossmounts fuse: Allow fuse_fill_super_common() for submounts fuse: split fuse_mount off of fuse_conn fuse: drop fuse_conn parameter where possible fuse: store fuse_conn in fuse_req fuse: add submount support to <uapi/linux/fuse.h> fuse: fix page dereference after free virtiofs: add logic to free up a memory range virtiofs: maintain a list of busy elements virtiofs: serialize truncate/punch_hole and dax fault path virtiofs: define dax address space operations virtiofs: add DAX mmap support virtiofs: implement dax read/write operations virtiofs: introduce setupmapping/removemapping commands virtiofs: implement FUSE_INIT map_alignment field virtiofs: keep a list of free dax memory ranges virtiofs: add a mount option to enable dax virtiofs: set up virtio_fs dax_device ... |

perf: correct SNOOPX field offset
perf_event.h has macros that define the field offsets in the
data_src bitmask in perf records. The SNOOPX and REMOTE offsets
were both 37. These are distinct fields, and the bitfield layout
in perf_mem_data_src confirms that SNOOPX should be at offset 38.
