The pid/killonerror test uses an invalid probe specifier to verify that
the child process is killed. It occasionally fails because the "date"
command is allowed to run long enough to print the date. This is harmless
in this case, but is clearly not ideal.
When the dt_proc_control thread is about to exit, and the dtrace command
forked the child, do not make the child runnable.

method didn't create a "class" nvpair in the event, which led to

This drops function `getexecname()` redirection.
Historically `getexecname()` is a compatibility definition. Since
openzfs has its own implementation of function `getexecname()` in libspl
and has been merged into base, the compat header file stdlib.h is
no longer needed and should not be used.
Also without this fix libspl will end up an incompatible version of
`getprogname()` with libc. In particular, if zfs is enabled, programs
such as pgrep in /rescue can be wrongly statically linked with libspl
and will not function properly.

When dtrace starts, it tries to detect if the dtrace klds are loaded,
and if not, it loads them by loading the dtraceall kld. This module
depends on most dtrace modules, including systrace for the native
freebsd and freebsd32 ABIs. However, it does not depend on the
systrace_linux klds, as they in turn depend on the linux ABI klds, and
we don't want to load an ABI module that the user has not explicitly
requested. This can leave a naive user in a state where they think all
syscall providers have been loaded, yet linux ABI syscalls are
"invisible" to dtrace.
To fix this, check to see if the linux ABI modules are loaded. If they
are, then load their systrace klds.

For the TCP protocol inpcb storage specify allocation size that would
provide space to most of the data a TCP connection needs, embedding
into struct tcpcb several structures, that previously were allocated
separately.
The most import one is the inpcb itself. With embedding we can provide
strong guarantee that with a valid TCP inpcb the tcpcb is always valid
and vice versa. Also we reduce number of allocs/frees per connection.
The embedded inpcb is placed in the beginning of the struct tcpcb,
since in_pcballoc() requires that. However, later we may want to move
it around for cache line efficiency, and this can be done with a little
effort. The new intotcpcb() macro is ready for such move.
The congestion algorithm data, the TCP timers and osd(9) data are
also embedded into tcpcb, and temprorary struct tcpcb_mem goes away.
There was no extra allocation here, but we went through extra pointer
every time we accessed this data.
One interesting side effect is that now TCP data is allocated from
SMR-protected zone. Potentially this allows the TCP stacks or other
TCP related modules to utilize that for their own synchronization.
Large part of the change was done with sed script:
s/tp->ccv->/tp->t_ccv./g
s/tp->ccv/\&tp->t_ccv/g
s/tp->cc_algo/tp->t_cc/g
s/tp->t_timers->tt_/tp->tt_/g
s/CCV\(ccv, osd\)/\&CCV(ccv, t_osd)/g
Dependency side effect is that code that needs to know struct tcpcb
should also know struct inpcb, that added several <netinet/in_pcb.h>.

This allows invop-based providers (i.e., fbt and kinst) to expose the
register file of the CPU at the point where the probe fired. It does
not work for SDT providers because their probes are implemented as plain
function calls and so don't save registers. It's not clear what
semantics "regs" should have for them anyway.
This is akin to "uregs", which nominally provides access to the
userspace registers. In fact, DIF already had a DIF_VAR_REGS variable
defined, it was simply unimplemented.
Usage example: print the contents of %rdi upon each call to
amd64_syscall():
fbt::amd64_syscall:entry {printf("%x", regs[R_RDI]);}
Note that the R_* constants are defined in /usr/lib/dtrace/regs_x86.d.
Currently there are no similar definitions for non-x86 platforms.

CTF integers have an explicit width and so can be used to represent
bitfields. Bitfield types emitted by ctfconvert(1) share the name of
the base integer type, so a struct field with type "unsigned int : 15"
will have a type named "unsigned int".
To avoid ambiguity when looking up types by name, add a suffix to names
of bitfield types to distinguish them from the base type. Then, if
ctfmerge happens to order bitfield types before the corresponding base
type in a CTF file, a name lookup will return the base type, which is
always going to be the desired behaviour.

These are based on definitions added to binutils' libctf. Specifically:
- Type IDs are now encoded in 32 bits rather than 16, changing the
layout of ctf_type_t, ctf_array_t, ctf_member_t and ctf_lmember_t.
- Type info is encoded in 32 bits rather than 16. The type "kind" is
extended from 5 bits to 6, and the type "vlen" is extended from 10
bits to 25.
The main upside is that we remove the current limit, imposed by CTFv2,
of 2^{15} distinct types in the main kernel executable. Other limits,
such as that on the number of elements in an enum, imposed by the vlen
limit, are also raised.
This change adds v2 and v3 flavours of macros and type definitions which
differ between the two versions. Compatibility is preserved for now by
having generic names refer to the v2 definitions, so, e.g., ctf_type_t
is still a v2 type.

OpenZFS commit: ec64fdb93d
When copying a struct or union from one CTF container to another,
ctf_add_type() checks whether it matches an existing type in the
destination container. It does so by looking for a type with the same
name and kind as the new type, and if one exists, it iterates over all
members of the source type and checks whether a member with matching
name and offset exists in the matched destination type. This can
produce false positives, for example because member types are not
compared, but this is not expected to arise in practice. If the match
fails, ctf_add_type() returns an error.
The procedure used for member comparison breaks down in the face of
anonymous struct and union members. ctf_member_iter() visits each
member in the source definition and looks up the corresponding member in
the desination definition by name using ctf_member_info(), but this
function will descend into anonymous members and thus fail to match.
Fix the problem by introducing a custom comparison routine which does
not assume member names are unique. This should also be faster for
types with many members; in the previous scheme, membcmp() would perform
a linear scan of the desination type's members to perform a lookup by
name. The new routine steps through the members of both types in a
single loop.

Because lld 13.0.0 is more strict about undefined references when
linking to shared libraries, it produces the following errors for zfsd:
ld: error: /home/dim/obj/home/dim/src/llvm-13-update/amd64.amd64/tmp/usr/lib/libzfs_core.so: undefined reference to libspl_assertf [--no-allow-shlib-undefined]
ld: error: /home/dim/obj/home/dim/src/llvm-13-update/amd64.amd64/tmp/usr/lib/libnvpair.so: undefined reference to libspl_assertf [--no-allow-shlib-undefined]
ld: error: /home/dim/obj/home/dim/src/llvm-13-update/amd64.amd64/tmp/usr/lib/libavl.so: undefined reference to libspl_assertf [--no-allow-shlib-undefined]
*** [zfsd.full] Error code 1
Fix this by adding libspl (where libspl_assertf lives) to zfsd's LIBADD.

From the zpool_influxdb.8 manual page:
zpool_influxdb produces InfluxDB-line-protocol-compatible metrics from
zpools. Like the zpool command, zpool_influxdb reads the current pool
status and statistics. Unlike the zpool command which is intended for
humans, zpool_influxdb formats the output in the InfluxDB line protocol.
The expected use is as a plugin to a metrics collector or aggregator,
such as Telegraf.
zpool_influxdb is installed into /usr/libexec/zfs/
