static_routes="foo bar:em0"
route_foo="-net 10.0.0.0/24 -gateway 192.168.2.1"
route_bar="-net 192.168.1.0/24 -gateway 192.168.0.2"
At boot time, all of the static routes are installed as before.
The differences are:
- "/etc/rc.d/netif start/stop <if>" now configures static routes
with :<if> if any.
- "/etc/rc.d/routing start/stop <af> <if>" works as well. <af> cannot be
omitted when <if> is specified, but a keyword "any" or "all" can be used
for <af> and <if>.

Problem caused by removal of $retval to capture exit status of call to
f_dialog_input_rclist().
While we're here, enhance f_dialog_input_rclist() to accept a default-item
to make selecting multiple values to-add more efficient.
The superblock in ext2fs defines all the fields as unsigned but for
some reason the in-memory superblock was carrying e2fs_bpg and
e2fs_isize as signed.
We should preserve the specified types for consistency.

Based on r134760:
Reset the seek pointer to 0 when a file is successfully opened,
since otherwise the initial seek offset will contain the directory
offset of the filesystem block that contained its directory entry.
This bug was mostly harmless because typically the directory is
less than one filesystem block in size so the offset would be zero.
It did however generally break loading a kernel from the (large)
kernel compile directory.
Also reset the seek pointer when a new inode is opened in read_inode(),
though this is not actually necessary now because all callers set
it afterwards.

After pushing in my fix for the 2 byte functions, I realized that the
functions for 1 and 2 byte operations had become identical. Reduce the
code size by merging the functions for 1 and 2 byte operations together.
While there, slightly improve variable naming and comments.
This small utility performs a sequence of atomic operations with random
parameters on an atomic variable. For every type, we also create 16
variables, to ensure that we test the correctness at different
alignments.

Typo was introduced by SVN r251361.
This is based on the AR933x (Hornet) SoC from Qualcomm Atheros.
It's a much nicer board to do development on - 64MB RAM, 16MB flash.
The development board breaks out the GPIO pins, ethernet, serial (via
a USB<->RS232 chip), USB host and of course a small wifi antenna.
Everything but the wifi works thus far.
"Login Management" module): Use default values for all account details?
If you select "Yes" (the default is "No"), you'll jump past all the prompts
and jump straight to the review screen with all-default values.
Makes adding a lot of users/groups faster/easier if you don't need to
customize more than one or two different values from their defaults.
fix the regression introduced by r251544; which was trying to make things
consistent w/respect to ESC versus YES versus NO in the password disable
prompt in "Login Management".
(need stronger coffee; very sorry for the churn)
With this revision, the "YES", "NO", and implied ESC options all work as-
expected. Choosing "YES" allows you to proceed and the password will be
disabled. Choosing "NO" will bring back around to enter a password for the
account. Pressing ESC will drop you out of either user or group input and
back to the usermgmt screen.
would like to disable password management for an account while adding either
a user or group. When being prompted to answer questions while adding a
group or user, two things are trow:
1. You can hit ENTER to blast through all the questions and in the end, the
group or user is created with sensible defaults for all values.
2. You can press ESC during any prompt to cancel the operation as a whole.
This fix is shoring up an inconsistency in the latter (#2).
which choosing to cancel the manual input of expiration time (in seconds
since the UNIX epoch) for either account expiration or password expiration
would see the original value lost.
Even though I tested the 1-byte operations on arbitrarily aligned bytes,
it seems I did not do this for the 2-byte operations.

To make <stdatomic.h> work on MIPS (and ARM) using GCC, we need to
provide implementations of the __sync_*() functions. I already added
these functions for 4 and 8 byte types to libcompiler-rt some time ago,
based on top of <machine/atomic.h>.
Unfortunately, <machine/atomic.h> only provides a subset of the features
needed to implement <stdatomic.h>. This means that in some cases we had
to do compare-and-exchange calls in loops, where a simple ll/sc would
suffice.
Also implement these functions for 1 and 2 byte types. MIPS only
provides ll/sc instructions for 4 and 8 byte types, but this is of
course no limitation. We can simply load 4 bytes and use some bitmask
tricks to modify only the bytes affected.

* Illumos ZFS issue #3805 arc shouldn't cache freed blocks
Quote from the Illumos issue:
ZFS should proactively evict freed blocks from the cache.
Even though these freed blocks will never be used again, and thus
will eventually be evicted, this causes us to use memory
inefficiently for 2 reasons:
1. A block that is freed has no chance of being accessed again, but
will be kept in memory preferentially to a block that was accessed
before it (and is thus older) but has not been freed and thus has
at least some chance of being accessed again.
2. We partition the ARC into several buckets:
user data that has been accessed only once (MRU)
metadata that has been accessed only once (MRU)
user data that has been accessed more than once (MFU)
metadata that has been accessed more than once (MFU)
The user data vs metadata split is somewhat arbitrary, and the
primary control on how much memory is used to cache data vs metadata
is to simply try to keep the proportion the same as it has been in the
past (each bucket "evicts against" itself). The secondary control is
to evict data before evicting metadata.
Because of this bucketing, we may end up with one bucket mostly
containing freed blocks that are very old, while another bucket has
more recently accessed, still-allocated blocks. Data in the useful
bucket (with still-allocated blocks) may be evicted in preference to
data in the useless bucket (with old, freed blocks).
On dcenter, we saw that the MFU metadata bucket was 230MB, while the
MFU data bucket was 27GB and the MRU metadata bucket was 256GB.
However, the vast majority of data in the MRU metadata bucket (256GB)
was freed blocks, and thus useless. Meanwhile, the MFU metadata bucket
(230MB) was constantly evicting useful blocks that will be soon needed.
The problem of cache segmentation is a larger problem that needs more
investigation. However, if we stop caching freed blocks, it should
reduce the impact of this more fundamental issue.

Store/restore the VFP registers in setjmp/longjmp on ARM EABI if VFP is
enabled in the kernel. It checks the hw.floatingpoint sysctl to see if
floating-point is available and uses this to determine if it should store
them. If it does it uses a different magic value so longjmp is able to know
if it should load them.
