for the default output. For '-a' (per-object needed printout) the
[preloaded] banner is kept.
Instead, use special format2 for printing the preloaded objects (and
vdso), which does not include DT_NEEDED, since there is no object
needing the printed one.
In this way, the output is more compatible with glibc.
Example:
LD_PRELOAD=/lib/libthr.so.3 LD_TRACE_LOADED_OBJECTS=1 /libexec/ld-elf.so.1 /bin/ls
libutil.so.9 => /lib/libutil.so.9 (0x801099000)

[vdso] (0x7ffffffff000)
/lib/libthr.so.3 (0x80106c000)
Note the absense of the part before and including '=>' for preloaded
libthr.so.3, and for vdso.

The current cloning KPI does not provide a way of creating interfaces
with parameres from within kernel. The reason is that those parameters
are passed as an opaque pointer and it is not possible to specify whether
this pointer references kernel-space or user-space.
Instead of just adding a flag, generalise the KPI to simplify the
extension process. Unify current notion of `SIMPLE` and `ADVANCED` users
by leveraging newly-added IFC_C_AUTOUNIT flag to automatically pick
unit number, which is a primary feature of the "SIMPLE" KPI.
Use extendable structures everywhere instead of passing function
pointers or parameters.
Isolate all parts of the oldKPI under `CLONE_COMPAT_13` so it can be safely
merged back to 13. Old KPI will be removed after the merge.

- The soisconnected() call on transition from SYN_RCVD to ESTABLISHED
is also necessary for a half-synchronized connection. Fix that
just setting the flag, when we transfer SYN-SENT -> SYN-RECEIVED.
- Provide a comment that explains at what conditions the call to
soisconnected() is necessary.
- Hence mechanically rename the TF_INCQUEUE flag to TF_SONOTCONN.
- Extend the change to the BBR and RACK stacks.
Note: the interaction between the accept_filter(9) and the socket layer
is not fully consistent, yet. For most accept filters this call to
soisconnected() will not move the connection from the incomplete queue
to the complete. The move would happen only when the filter has received
the desired data, and soisconnected() would be called once again from
sorwakeup(). Ideally, we should mark socket as connected only there,
and leave the soisconnected() from SYN_RCVD->ESTABLISHED only for the
simultaneous open case. However, this doesn't yet work.

the softc after the module is unloaded and the M_OVPN malloc type no

Don't return from ovpn_clone_destroy() until the epoch callbacks have

RB-tree augmentation maintains data in each node of the tree that
represents the product of some associative operator applied to all the
nodes of the subtree rooted at that node. If a node in the tree
changes, augmentation data for the node is updated for that node and
all nodes on the path from that node to the tree root. However,
sometimes, augmenting a node changes no data in that node,
particularly if the associated operation is something involving 'max'
or 'min'. If augmentation changes nothing in a node, then the work of
walking to the tree root from that point is pointless, because
augmentation will change nothing in those nodes either. This change
makes it possible to avoid that wasted work.
Define RB_AUGMENT_CHECK as a macro much like RB_AUGMENT, but which
returns a value 'true' when augmentation changes the augmentation data
of a node, and false otherwise. Change code that unconditionally walks
and augments to the top of tree to code that stops once an
augmentation has no effect. In the case of rebalancing the tree after
insertion or deletion, where previously a node rotated into the path
was inevitably augmented on the march to the tree root, now check to
see if it needs augmentation because the march to the tree root
stopped before reaching it.
Change the augmentation function in iommu_gas.c so that it returns
true/false to indicate whether the augmentation had any effect.
