- most of the kernel code will not care about the actual encoding of
scope zone IDs and won't touch "s6_addr16[1]" directly.
- similarly, most of the kernel code will not care about link-local
scoped addresses as a special case.
- scope boundary check will be stricter. For example, the current
*BSD code allows a packet with src=::1 and dst=(some global IPv6
address) to be sent outside of the node, if the application do:
s = socket(AF_INET6);
bind(s, "::1");
sendto(s, some_global_IPv6_addr);
This is clearly wrong, since ::1 is only meaningful within a single
node, but the current implementation of the *BSD kernel cannot
reject this attempt.

It creates very huge provider (41PB) /dev/gzero.
On BIO_READ request it zero-fills bio_data and on BIO_WRITE it does nothing.
You can also set kern.geom.zero.clear sysctl to 0 to do nothing even for
BIO_READ.
I'm using it for performance testing where it is very helpful.

be used to pass statistics regarding dropped, matched and received
packet counts from the kernel to user-space. While we are here
introduce a new counter for filtered or matched packets. We currently
keep track of packets received or dropped by the bpf device, but not
how many packets actually matched the bpf filter.
-Introduce net.bpf.stats sysctl OID
-Move sysctl variables after the function prototypes so we can
reference bpf_stats_sysctl(9) without build errors.
-Introduce bpf descriptor counter which is used mainly for sizing
of the xbpf_d array.
-Introduce a xbpf_d structure which will act as an external
representation of the bpf_d structure.
-Add a the following members to the bpfd structure:
bd_fcount - Number of packets which matched bpf filter
bd_pid - PID which opened the bpf device
bd_pcomm - Process name which opened the device.
It should be noted that it's possible that the process which opened
the device could be long gone at the time of stats collection. An
example might be a process that opens the bpf device forks then exits
leaving the child process with the bpf fd.

conversion routine, now change my mind and add one, memstat_strerror(3),
which returns a const char * pointer to a string describing the error,
to be used on the results of memstat_mtl_geterror().

Pointers on improving ease of internationalization would be

- Define a set of libmemstat(3) error constants, which are used by all
libmemstat(3) methods except for memstat_mtl_alloc(), which allocates
a memory type list and may return ENOMEM via errno.
- Define a per-memory_type_list current error value, which is set when a
call associated with a memory list fails. This requires wrapping a
structure around the queue(9) list head data structure, but this change
is not visible to libmemstat(3) consumers due to using access methods.
- Add a new accessor method, memstat_mtl_geterror() to retrieve the error
number.
- Consistently set the error number in a number of failure modes where
previously some combination of setting errno and printf'ing error
descriptions was used. libmemstat(3) will now no longer print to stdio
under any circumstances. Returns of NULL/-1 for errors remain the
same.
This avoids use of stdio, misuse of error numbers, and should make it
easier to program a libmemstat(3) consumer able to print useful error
messages. Currently, no error-to-string function is provided, as I'm
unsure how to address internationalization concerns.

(i.e., smart battery) and fix various bugs found during the cleanup.
API changes:
* kernel access:
Access to individual batteries is now via devclass_find("battery").
Introduce new methods ACPI_BATT_GET_STATUS (for _BST-formatted data) and
ACPI_BATT_GET_INFO (for _BIF-formatted data). The helper function
acpi_battery_get_battinfo() now takes a device_t instead of a unit #
argument. If dev is NULL, this signifies all batteries.
* ioctl access:
The ACPIIO_BATT_GET_TYPE and ACPIIO_BATT_GET_BATTDESC ioctls have been
removed. Since there is now no need for a mapping between "virtual" unit
and physical unit, usermode programs can just specify the unit directly and
skip the old translation steps. In fact, acpiconf(8) was actually already
doing this and virtual unit was the same as physical unit in all cases
since there was previously only one battery type (acpi_cmbat). Additionally,
we now map the ACPIIO_BATT_GET_BIF and ACPIIO_BATT_GET_BST ioctls for all
batteries, if they provide the associated methods.
* apm compatibility device/ioctls: no change
* sysctl: no change
Since most third-party applications use the apm(4) compat interface, there
should be very few affected applications (if any).

So, back out the back out and return srandomdev().
People who have problems with repeated quotes should use -D fortune

I will be glad to help, but I can't reproduce repeated quote situation

In either case found, (1) or (2) should be fixed instead of removing
srandomdev().
We must not increase a capability of buffer size here,
because codes which call these functions expect that dst and src
are the same size.

- works in interactive (default) and batch mode
- respects DISTDIR
- documented in UPDATING and build(7)
The head of the file ObsoleteFiles.inc contains instructions how to add
obsolete files/dirs/libs to the list. Obviously one should add obsolete
files to this list, when he removes a file/dir/lib from the basesystem.
Additionally add check-old target:
- allows re@ to check if a file on the obsolete list resurfaces
Design goals:
- allows full control by the user (default interactive mode)
- possibility of scripted removal of obsolete files (batch mode)
- opt-in removal of files (explicit list of files)
- seperate removal of libs (2 delete targets)
Important design decissions:
- structured list of files to remove instead of a plain text file:
* allows to remove additional files if a NO_foo knob is specified
without the need to change the targets (no NO_foo knob is respected
yet)
- not using mtree like NetBSD does:
* mtree doesn't has an interactive mode
