Commit dae1713419 did not add two required lines for edonr specific
functionality to this file, causing kernel build failures if ZFS is
compiled in.
This commit should be included in an eventual MFC of dae1713419.
NOTE: HEADS UP read the note below if your kernel config is not including GENERIC!!
This patch does a bit of cleanup on TCP congestion control modules. There were some rather
interesting surprises that one could get i.e. where you use a socket option to change
from one CC (say cc_cubic) to another CC (say cc_vegas) and you could in theory get
a memory failure and end up on cc_newreno. This is not what one would expect. The
new code fixes this by requiring a cc_data_sz() function so we can malloc with M_WAITOK
and pass in to the init function preallocated memory. The CC init is expected in this
case *not* to fail but if it does and a module does break the
"no fail with memory given" contract we do fall back to the CC that was in place at the time.
This also fixes up a set of common newreno utilities that can be shared amongst other
CC modules instead of the other CC modules reaching into newreno and executing
what they think is a "common and understood" function. Lets put these functions in
cc.c and that way we have a common place that is easily findable by future developers or
bug fixers. This also allows newreno to evolve and grow support for its features i.e. ABE
and HYSTART++ without having to dance through hoops for other CC modules, instead
both newreno and the other modules just call into the common functions if they desire
that behavior or roll there own if that makes more sense.
Note: This commit changes the kernel configuration!! If you are not using GENERIC in
some form you must add a CC module option (one of CC_NEWRENO, CC_VEGAS, CC_CUBIC,
CC_CDG, CC_CHD, CC_DCTCP, CC_HTCP, CC_HD). You can have more than one defined
as well if you desire. Note that if you create a kernel configuration that does not
define a congestion control module and includes INET or INET6 the kernel compile will
break. Also you need to define a default, generic adds 'options CC_DEFAULT=\"newreno\"
but you can specify any string that represents the name of the CC module (same names
that show up in the CC module list under net.inet.tcp.cc). If you fail to add the
options CC_DEFAULT in your kernel configuration the kernel build will also break.

The last two drivers that required sppp are cp(4) and ce(4).
These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.
Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially. Later they have dropped
support for Linux drivers to. As of mid-2020 they don't even
have a developer to maintain their Windows driver. However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.
These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP. Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.
Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part. Further maintenance of these
drivers in the tree shouldn't be a big deal.
While doing that, remove some cruft and enable cp(4) compilation
on amd64. The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.

- kern_kcov.c needs to be compiled with -fsanitize=kernel-memory when
KMSAN is configured since it calls into various other subsystems.
- Disable address and memory sanitizers in kcov(4)'s coverage sanitizer
callbacks, as they do not provide useful checking. Moreover, with
KMSAN we may otherwise get false positives since the caller (coverage

- Disable KASAN and KMSAN interceptors in subr_coverage.c, as they do
not provide any benefit but do introduce overhead when fuzzing.

KMSAN enables the use of LLVM's MemorySanitizer in the kernel. This
enables precise detection of uses of uninitialized memory. As with
KASAN, this feature has substantial runtime overhead and is intended to
be used as part of some automated testing regime.
The runtime maintains a pair of shadow maps. One is used to track the
state of memory in the kernel map at bit-granularity: a bit in the
kernel map is initialized when the corresponding shadow bit is clear,
and is uninitialized otherwise. The second shadow map stores
information about the origin of uninitialized regions of the kernel map,
simplifying debugging.
KMSAN relies on being able to intercept certain functions which cannot
be instrumented by the compiler. KMSAN thus implements interceptors
which manually update shadow state and in some cases explicitly check
for uninitialized bytes. For instance, all calls to copyout() are
subject to such checks.
The runtime exports several functions which can be used to verify the
shadow map for a given buffer. Helpers provide the same functionality
for a few structures commonly used for I/O, such as CAM CCBs, BIOs and
mbufs. These are handy when debugging a KMSAN report whose
proximate and root causes are far away from each other.

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):

KASAN enables the use of LLVM's AddressSanitizer in the kernel. This
feature makes use of compiler instrumentation to validate memory
accesses in the kernel and detect several types of bugs, including
use-after-frees and out-of-bounds accesses. It is particularly
effective when combined with test suites or syzkaller. KASAN has high
CPU and memory usage overhead and so is not suited for production
environments.
The runtime and pmap maintain a shadow of the kernel map to store
information about the validity of memory mapped at a given kernel
address.
The runtime implements a number of functions defined by the compiler
ABI. These are prefixed by __asan. The compiler emits calls to
__asan_load*() and __asan_store*() around memory accesses, and the
runtime consults the shadow map to determine whether a given access is
valid.
kasan_mark() is called by various kernel allocators to update state in
the shadow map. Updates to those allocators will come in subsequent
commits.
The runtime also defines various interceptors. Some low-level routines
are implemented in assembly and are thus not amenable to compiler
instrumentation. To handle this, the runtime implements these routines
on behalf of the rest of the kernel. The sanitizer implementation
validates memory accesses manually before handing off to the real
implementation.
The sanitizer in a KASAN-configured kernel can be disabled by setting
the loader tunable debug.kasan.disable=1.

On top of that the routine can is a starting point for copyinstr

case.
Addmittingly lkpi_devm_kmalloc_release() could be avoided but for
the overall understanding of the code and possible memory tracing
it may still be helpful.
Further devsres consumer are implemented for iwlwifi but will follow

Update the MMIO driver to reflect the VirtIO bus method changes, but
the modern compliance can be improved on later.
Note that the modern PCI driver requires bus_map_resource() to be
implemented, which is not the case on all archs.
The hw.virtio.pci.transitional tunable default value is zero so
transitional devices will continue to be driven via the legacy
driver.

This driver provides raw access to HID devices through uhid(4)-compatible
interface and is based on pre-8.x uhid(4) code. Unlike uhid(4) it does
not take devices in to monopoly ownership and allows parallel access
from other drivers.
hidraw supports Linux's hidraw-compatible interface as well.

This change implements hid_if.m methods for HID-over-USB protocol [1].
Also, this change adds USBHID_ENABLED kernel option which changes

over ums, ukbd, wmt and other USB HID device drivers and vice-versa.
The module is based on uhid(4) driver. It is disabled by default for

This driver provides support for multiple HID driver attachments
to single HID transport backend. This ability existed in Net/OpenBSD
(uhidev and ihidev drivers) but has never been ported to FreeBSD.
Unlike Net/OpenBSD we do not use report number alone to distinct report
source but we follow MS way and use a top level collection (TLC) usage
index that report belongs to as a location key.
The driver performs child device autodiscovery based on HID report
descriptor data, proxying of HID requests from child devices to parent
transport backends and broadcasting of interrupts in backward direction.

eventfd is a Linux system call that produces special file descriptors
for event notification. When porting Linux software, it is currently
usually emulated by epoll-shim on top of kqueues. Unfortunately, kqueues
are not passable between processes. And, as noted by the author of
epoll-shim, even if they were, the library state would also have to be
passed somehow. This came up when debugging strange HW video decode
failures in Firefox. A native implementation would avoid these problems
and help with porting Linux software.
Since we now already have an eventfd implementation in the kernel (for
the Linuxulator), it's pretty easy to expose it natively, which is what
this patch does.

These drivers should have been removed along with tl(4) as part of
7c897ca91f and r347918 respectively
as these fromer made sure to only ever attach to the latter, e. g.:

return (ENXIO);

This change introduces framework that allows to dynamically
attach or detach longest prefix match (lpm) lookup algorithms
to speed up datapath route tables lookups.
Framework takes care of handling initial synchronisation,
route subscription, nhop/nhop groups reference and indexing,
dataplane attachments and fib instance algorithm setup/teardown.
Framework features automatic algorithm selection, allowing for
picking the best matching algorithm on-the-fly based on the
amount of routes in the routing table.
Currently framework code is guarded under FIB_ALGO config option.
An idea is to enable it by default in the next couple of weeks.
The following algorithms are provided by default:
IPv4:
* bsearch4 (lockless binary search in a special IP array), tailored for
small-fib (<16 routes)
* radix4_lockless (lockless immutable radix, re-created on every rtable change),
tailored for small-fib (<1000 routes)
* radix4 (base system radix backend)
* dpdk_lpm4 (DPDK DIR24-8-based lookups), lockless datastrucure, optimized
for large-fib (D27412)
IPv6:
* radix6_lockless (lockless immutable radix, re-created on every rtable change),
tailed for small-fib (<1000 routes)
* radix6 (base system radix backend)
* dpdk_lpm6 (DPDK DIR24-8-based lookups), lockless datastrucure, optimized
for large-fib (D27412)
Performance changes:
Micro benchmarks (I7-7660U, single-core lookups, 2048k dst, code in D27604):
IPv4:
8 routes:
radix4: ~20mpps
radix4_lockless: ~24.8mpps
bsearch4: ~69mpps
dpdk_lpm4: ~67 mpps
700k routes:
radix4_lockless: 3.3mpps
dpdk_lpm4: 46mpps
IPv6:
8 routes:
radix6_lockless: ~20mpps
dpdk_lpm6: ~70mpps
100k routes:
radix6_lockless: 13.9mpps
dpdk_lpm6: 57mpps
Forwarding benchmarks:
+ 10-15% IPv4 forwarding performance (small-fib, bsearch4)
+ 25% IPv4 forwarding performance (full-view, dpdk_lpm4)
+ 20% IPv6 forwarding performance (full-view, dpdk_lpm6)
Control:
Framwork adds the following runtime sysctls:
List algos
* net.route.algo.inet.algo_list: bsearch4, radix4_lockless, radix4
* net.route.algo.inet6.algo_list: radix6_lockless, radix6, dpdk_lpm6
Debug level (7=LOG_DEBUG, per-route)
net.route.algo.debug_level: 5
Algo selection (currently only for fib 0):
net.route.algo.inet.algo: bsearch4
net.route.algo.inet6.algo: radix6_lockless
Support for manually changing algos in non-default fib will be added
soon. Some sysctl names will be changed in the near future.
