Overview:
This is the first stage of a RDMA stack upgrade introducing kernel
changes only based on Linux 5.7-rc1.
This patch is based on about four main areas of work:
- Update of the IB uobjects system:
- The memory holding so-called AH, CQ, PD, SRQ and UCONTEXT objects
is now managed by ibcore. This also require some changes in the
kernel verbs API. The updated verbs changes are typically about
initialize and deinitialize objects, and remove allocation and
free of memory.
- Update of the uverbs IOCTL framework:
- The parsing and handling of user-space commands has been
completely refactored to integrate with the updated IB uobjects
system.
- Various changes and updates to the generic uverbs interfaces in
device drivers including the new uAPI surface.
- The mlx5_ib_devx.c in mlx5ib and related mlx5 core changes.
Dependencies:
- The mlx4ib driver code has been updated with the minimum changes
needed.
- The mlx5ib driver code has been updated with the minimum changes
needed including DV support.
Compatibility:
- All user-space facing APIs are backwards compatible after this
change.
- All kernel-space facing RDMA APIs are backwards compatible after
this change, with exception of ib_create_ah() and ib_destroy_ah()
which takes a new flag.
- The "ib_device_ops" structure exist, but only contains the driver ID
and some structure sizes.
Differences from Linux:
- Infiniband drivers must use the INIT_IB_DEVICE_OPS() macro to set
the sizes needed for allocating various IB objects, when adding
IB device instances.
Security:
- PRIV_NET_RAW is needed to use raw ethernet transmit features.
- PRIV_DRIVER is needed to use other privileged operations.
Based on upstream Linux, Torvalds (5.7-rc1):

Import OpenBSD's syncookie support for pf. This feature help pf resist
TCP SYN floods by only creating states once the remote host completes
the TCP handshake rather than when the initial SYN packet is received.
This is accomplished by using the initial sequence numbers to encode a
cookie (hence the name) in the SYN+ACK response and verifying this on
receipt of the client ACK.

The vDSO (virtual dynamic shared object) is a small shared library that the
kernel maps R/O into the address space of all Linux processes on image
activation. The vDSO is a fully formed ELF image, shared by all processes
with the same ABI, has no process private data.
The primary purpose of the vDSO:
- non-executable stack, signal trampolines not copied to the stack;
- signal trampolines unwind, mandatory for the NPTL;
- to avoid contex-switch overhead frequently used system calls can be
implemented in the vDSO: for now gettimeofday, clock_gettime.
The first two have been implemented, so add the implementation of system
calls.
System calls implemenation based on a native timekeeping code with some
limitations:
- ifunc can't be used, as vDSO r/o mapped to the process VA and rtld
can't relocate symbols;
- reading HPET memory is not implemented for now (TODO).
In case on any error vDSO system calls fallback to the kernel system
calls. For unimplemented vDSO system calls added prototypes which call
corresponding kernel system call.

OpenZFS commit: 75b4cbf625
The vmbus ISR needs to live in a trampoline. Dynamically allocating a
trampoline at driver initialization time poses some difficulties due to
the fact that the KENTER macro assumes that the offset relative to
tramp_idleptd is fixed at static link time. Another problem is that
native_lapic_ipi_alloc() uses setidt(), which assumes a fixed trampoline
offset.
Rather than fight this, move the Hyper-V ISR to i386/exception.s. Add a
new HYPERV kernel option to make this optional, and configure it by
default on i386. This is sufficient to make use of vmbus(4) after the
4/4 split. Note that vmbus cannot be loaded dynamically and both the
HYPERV option and device must be configured together. I think this is
not too onerous a requirement, since vmbus(4) was previously
non-functional.

DXR maintains compressed lookup structures with a trivial search
procedure. A two-stage trie is indexed by the more significant bits of
the search key (IPv4 address), while the remaining bits are used for
finding the next hop in a sorted array. The tradeoff between memory
footprint and search speed depends on the split between the trie and
the remaining binary search. The default of 20 bits of the key being
used for trie indexing yields good performance (see below) with
footprints of around 2.5 Bytes per prefix with current BGP snapshots.
Rebuilding lookup structures takes some time, which is compensated for by
batching several RIB change requests into a single FIB update, i.e. FIB
synchronization with the RIB may be delayed for a fraction of a second.
RIB to FIB synchronization, next-hop table housekeeping, and lockless
lookup capability is provided by the FIB_ALGO infrastructure.
DXR works well on modern CPUs with several MBytes of caches, especially
in VMs, where is outperforms other currently available IPv4 FIB
algorithms by a large margin.
Synthetic single-thread LPM throughput test method:
kldload test_lookup; kldload dpdk_lpm4; kldload fib_dxr
sysctl net.route.test.run_lps_rnd=N
sysctl net.route.test.run_lps_seq=N
where N is the number of randomly generated keys (IPv4 addresses) which
should be chosen so that each test iteration runs for several seconds.
Each reported score represents the best of three runs, in million
lookups per second (MLPS), for two bechmarks (RND & SEQ) with two FIBs:
host: single interface address, local subnet route + default route
BGP: snapshot from linx.routeviews.org, 887957 prefixes, 496 next hops
