probe. The current device order is unchanged. This commit just adds the
infrastructure and ABI changes so that it is easier to merge later changes
into 8.x.
- Driver attachments now have an associated pass level. Attachments are
not allowed to probe or attach to drivers until the system-wide pass level
is >= the attachment's pass level. By default driver attachments use the
"last" pass level (BUS_PASS_DEFAULT). Driver's that wish to probe during
an earlier pass use EARLY_DRIVER_MODULE() instead of DRIVER_MODULE() which
accepts the pass level as an additional parameter.
- A new method BUS_NEW_PASS has been added to the bus interface. This
method is invoked when the system-wide pass level is changed to kick off
a rescan of the device tree so that drivers that have just been made
"eligible" can probe and attach.
- The bus_generic_new_pass() function provides a default implementation of
BUS_NEW_PASS(). It first allows drivers that were just made eligible for
this pass to identify new child devices. Then it propogates the rescan to
child devices that already have an attached driver by invoking their
BUS_NEW_PASS() method. It also reprobes devices without a driver.
- BUS_PROBE_NOMATCH() is only invoked for devices that do not have
an attached driver after being scanned during the final pass.
- The bus_set_pass() function is used during boot to raise the pass level.
Currently it is only called once during root_bus_configure() to raise
the pass level to BUS_PASS_DEFAULT. This has the effect of probing all
devices in a single pass identical to previous behavior.

From the submitter:
DIN 5008 (German norm for text processing) defines the old date
format (%d.%m.%Y) to be obsolete and to be used only, if unambigous.
In international communications the new format (%Y-%m-%d) is now
required and FreeBSD should respect this.

version field sent via gif(4)+if_bridge(4). The EtherIP
implementation found on FreeBSD 6.1, 6.2, 6.3, 7.0, 7.1, and 7.2 had
an interoperability issue because it sent the incorrect EtherIP
packets and discarded the correct ones.
This change introduces the following two flags to gif(4):
accept_rev_ethip_ver: accepts both correct EtherIP packets and ones
with reversed version field, if enabled. If disabled, the gif
accepts the correct packets only. This flag is enabled by
default.
send_rev_ethip_ver: sends EtherIP packets with reversed version field
intentionally, if enabled. If disabled, the gif sends the correct
packets only. This flag is disabled by default.
These flags are stored in struct gif_softc and can be set by
ifconfig(8) on per-interface basis.
Note that this is an incompatible change of EtherIP with the older
FreeBSD releases. If you need to interoperate older FreeBSD boxes and
new versions after this commit, setting "send_rev_ethip_ver" is
needed.

the number of days between backups. All it says is frequency, with no
units given. It likely should say "the interval in days between backups"
instead, but not today.
In Portuguese, the names of the days of the week are not capitalized.
Also there is always a dash before "feira" in the names of the days.
For example: "segunda-feira" and not "segunda feira" (which has a
completely different meaning).
x_fmt is not correct either. The date separator should not be a dot
but a slash. Example: 31/12/2005 if far more used in Portugal than
31.12.2005.

Each list describes a logical memory object that is backed by one or more
physical address ranges. To minimize locking, the sglist objects
themselves are immutable once they are shared.
These objects may be used in the future to facilitate I/O requests using
physically-addressed buffers. For the immediate future I plan to use them
to implement a new type of VM object and pager.

We will look at renaming stuff for 9.0, but it's far from certain that we

ariff's next mega-patch goes in, and having everything sorted makes my
job easier.
While there remain some incomplete aspects of the implementation (such
as incomplete auditing of some system calls), the implementation has

- Add rm_init_flags() and accept extended options only for that variation.

the lock_init() flag space.
- Define flag RM_RECURSE to use instead of LO_RECURSABLE.
- Define flag RM_NOWITNESS to allow an rmlock to be exempt from WITNESS
checking; this wasn't possible previously as rm_init() always passed
LO_WITNESS when initializing an rmlock's struct lock.

Introduce for this operation the reverse NO_ADAPTIVE_SX option.
The flag SX_ADAPTIVESPIN to be passed to sx_init_flags(9) gets suppressed
and the new flag, offering the reversed logic, SX_NOADAPTIVE is added.
Additively implements adaptive spininning for sx held in shared mode.
The spinning limit can be handled through sysctls in order to be tuned
while the code doesn't reach the release, after which time they should
be dropped probabilly.
This change has made been necessary by recent benchmarks where it does
improve concurrency of workloads in presence of high contention
(ie. ZFS).
KPI breakage is documented by __FreeBSD_version bumping, manpage and

Last year I added SLIST_REMOVE_NEXT and STAILQ_REMOVE_NEXT, to remove
entries behind an element in the list, using O(1) time. I recently
discovered NetBSD also has a similar macro, called SLIST_REMOVE_AFTER.
In my opinion this approach is a lot better:
- It doesn't have the unused first argument of the list pointer. I added
this, mainly because OpenBSD also had it.
- The _AFTER suffix makes a lot more sense, because it is related to
SLIST_INSERT_AFTER. _NEXT is only used to iterate through the list.
The reason why I want to rename this now, is to make sure we don't
release a major version with the badly named macros.
ip6_input.c, in6.h:
* Add netinet6-specific mbuf flag M_RTALERT_MLD, shadowing M_PROTO6.
* Always set this flag if HBH Router Alert option is present for MLD,
even when not forwarding.
icmp6.c:
* In icmp6_input(), spell m->m_pkthdr.rcvif as ifp to be consistent.
* Use scope ID for verifying input. Do not apply SSM filters here, no inpcb.
* Check for M_RTALERT_MLD when validating MLD traffic, as we can't see
IPv6 hop options outside of ip6_input().
in6_mcast.c:
* Use KAME scope/zone ID in in6_multi.
* Update net.inet6.ip6.mcast.filters implementation to use scope IDs
for comparisons.
* Fix scope ID treatment in multicast socket option processing.
Scope IDs passed in from userland will be ignored as other less
ambiguous APIs exist for specifying the link.
* Tighten userland input checks in IPv6 SSM delta and full-state ops.
* Source filter embedded scope IDs need to be revisited, for now
just clear them and ignore them on input.
* Adapt KAME behaviour of looking up the scope ID in the default zone
for multicast leaves, when the interface is ambiguous.
mld6.c:
* Tighten origin checks on MLD traffic as per RFC3810 Section 6.2:
* ip6_src MAY be the unspecified address for MLDv1 reports.
* ip6_src MAY have link-local address scope for MLDv1 reports,
MLDv1 queries, and MLDv2 queries.
* Perform address field validation *before* accepting queries.
* Use KAME scope/zone ID in query/report processing.
* Break const correctness for mld_v1_input_report(), mld_v1_input_query()
as we temporarily modify the input mbuf chain.
* Clear the scope ID before handoff to userland MLD daemon.
* Fix MLDv1 old querier present timer processing.
With the protocol defaults, hosts should revert to MLDv2 after 260s.
* Add net.inet6.mld.v1enable sysctl, default to on.
ifmcstat.c:
* Use sysctl by default; -K requests kvm(3) if so compiled.
mld.4:
* Connect man page to build.

get a quick snapshot of the kernel's symbol table including the symbols
from any loaded modules (the symbols are all merged into one symbol
table). Unlike like other implementations, this ksyms driver maps
memory in the process memory space to store the snapshot at the time
/dev/ksyms is opened. It also checks to see if the process has already
a snapshot open and won't allow it to open /dev/ksyms it again until it
closes first. This prevents kernel and process memory from being
exhausted. Note that /dev/ksyms is used by the lockstat(1) command.
