Alternative NTP implementations should add a:
Conflicts=systemd-timesyncd.service
to take over the built-in NTP functionality of systemd.

The new lzma2 compression options at the top of compress_blob_xz are
equivalent to using preset "0", exept for using a 1 MiB dictionary
(the same as preset "1"). This makes the memory usage at most 7.5 MiB
in the compressor, and 1 MiB in the decompressor, instead of the
previous 92 MiB in the compressor and 8 MiB in the decompressor.
According to test-compress-benchmark this commit makes XZ compression
20 times faster, with no increase in compressed data size.
Using more realistic test data (an ELF binary rather than repeating
ASCII letters 'a' through 'z' in order) it only provides a factor 10
speedup, and at a cost if a 10% increase in compressed data size.
But that is still a worthwhile trade-off.
According to test-compress-benchmark XZ compression is still 25 times
slower than LZ4, but the compressed data is one eighth the size.
Using more realistic test data XZ compression is only 18 times slower
than LZ4, and the compressed data is only one quarter the size.
$ ./test-compress-benchmark
XZ: compressed & decompressed 2535300963 bytes in 42.30s (57.15MiB/s), mean compresion 99.95%, skipped 3570 bytes
LZ4: compressed & decompressed 2535303543 bytes in 1.60s (1510.60MiB/s), mean compresion 99.60%, skipped 990 bytes

Instead of waiting for new data from the sensor, which might be
a long time coming, depending on the sensor device, ask the kernel
for the last state for that particular input device.

If compositors use the new SwitchTo() logic to map F1-F12, we should allow
them to switch to unregistered VTs, too. Otherwise, the auto-spawn logic
of gettys won't trigger.

sd-event makes handling SIGTERM/SIGINT a lot easier than it used to,
let's make use of this
|
|
|
|
|
|
|
|
Add various options for making it easy unescape, or mangle, or format as
template instance or append a suffix.

xxx,x-systemd.default-timeout=y,zzz was filtered to xxxzzz,
but should be xxx,zzz, of course.

This patch adds supports networkd to configure bond mode
during creation via persistent conf. Mode can be configured
with conf param 'Mode'. A new section Bond is added to the
conf to support bond mode.
These modes can be configured now.
balance-rr
active-backup
balance-xor
broadcast
802.3ad
balance-tlb
balance-alb
Example conf file: test-bond.conf
[NetDev]
Name=bond1
Kind=bond
[Bond]
Mode=balance-xor
Test case:
1. start networkd service:
12: bond1: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc
noqueue state UNKNOWN mode DEFAULT group default
link/ether 22:89:6c:47:23:d2 brd ff:ff:ff:ff:ff:ff
2. find bond mode:
cat /proc/net/bonding/bond1
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)
Bonding Mode: load balancing (xor)
Transmit Hash Policy: layer2 (0)
MII Status: up
MII Polling Interval (ms): 0
Up Delay (ms): 0
Down Delay (ms): 0
Changes:
1. Added file networkd-bond.c
2. Bond mode enum BondMode
3. conf section [Bond]

It's more appropriate to make it's assert than -ENOTSUP

ConditionFirstBoot= instead
As Zbigniew pointed out a new ConditionFirstBoot= appears like the nicer
way to hook in systemd-firstboot.service on first boots (those with /etc
unpopulated), so let's do this, and get rid of the generator again.

NULSTR_FOREACH() looks for a terminating zero and the element also needs
one.
|
|
We shouldn't show status texts from previous service starts
|
|
|
|
|
|
|
|
StatusErrno dbus property along StatusText to allow notification of numeric status condition while degraded service operation or any other special situation.
|
|
It appears to be customary to remove all access bits from /etc/shadow
including those for the root owner), hence let's do the same.

Reading BPF assembly written as C macros is inherently difficult. Don't
make it harder than necessary and provide clearer explanation in the
comment.

We already ignore IP fragments, because we expect that Fragment
offset (FO) field is not set. However first fragment in a fragmented IP
flow will have all zeroes in FO field. We should ignore such packet as
well, thus we need to look at MF flag in the IP header. Checking MF flag
will filter out all except last packet in fragmented flows. Last one
will be ruled out by next check for value of FO.

or when creating OS images offline
A new tool "systemd-firstboot" can be used either interactively on boot,
where it will query basic locale, timezone, hostname, root password
information and set it. Or it can be used non-interactively from the
command line when prepareing disk images for booting. When used
non-inertactively the tool can either copy settings from the host, or
take settings on the command line.
$ systemd-firstboot --root=/path/to/my/new/root --copy-locale --copy-root-password --hostname=waldi
The tool will be automatically invoked (interactively) now on first boot
if /etc is found unpopulated.
This also creates the infrastructure for generators to be notified via
an environment variable whether they are running on the first boot, or
not.

Instead, take a list of exceptions to our usual CC check
|
|
This way we can reuse it other code thatn just localectl/localed +
timedatectl/timedated.

Let's better be safe than sorry.

Otherwis, we get misleading error messages on links with MACs.

Without this, the underlying device would get freed (and hence
fail).

This patch adds peer address support for
networkd . In the [Address] a new configurable
param is Peer.
[Match]
Name=ipip-tun
[Address]
Address=10.0.0.1/32
Peer=10.0.0.2/32
|
|
Check that received DHCP packets actually include our MAC address in
chaddr field. BPF interpreter has 32 bit wide registers but MAC address
is 48 bits long so we have to do check in two steps.

This is useful to test the behaviour of the compressor for various buffer
sizes.
Time is limited to a minute per compression, since otherwise, when LZ4
takes more than a second which is necessary to reduce the noise, XZ
takes more than 10 minutes.
% build/test-compress-benchmark (without time limit)
XZ: compressed & decompressed 2535300963 bytes in 794.57s (3.04MiB/s), mean compresion 99.95%, skipped 3570 bytes
LZ4: compressed & decompressed 2535303543 bytes in 1.56s (1550.07MiB/s), mean compresion 99.60%, skipped 990 bytes
% build/test-compress-benchmark (with time limit)
XZ: compressed & decompressed 174321481 bytes in 60.02s (2.77MiB/s), mean compresion 99.76%, skipped 3570 bytes
LZ4: compressed & decompressed 2535303543 bytes in 1.63s (1480.83MiB/s), mean compresion 99.60%, skipped 990 bytes
It appears that there's a bug in lzma_end where it leaks 32 bytes.

Add liblz4 as an optional dependency when requested with --enable-lz4,
and use it in preference to liblzma for journal blob and coredump
compression. To retain backwards compatibility, XZ is used to
decompress old blobs.
Things will function correctly only with lz4-119.
Based on the benchmarks found on the web, lz4 seems to be the best
choice for "quick" compressors atm.
For pkg-config status, see http://code.google.com/p/lz4/issues/detail?id=135.

uncompress_startswith would always decode the whole stream, even
if it did not start with the given prefix.
Reallocation policy was also strange.
