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.

This patch introduces TUN/TAP device creation support
to networkd.
Example conf to create a tap device:
file: tap.netdev
------------------
[NetDev]
Name=tap-test
Kind=tap
[Tap]
OneQueue=true
MultiQueue=true
PacketInfo=true
User=sus
Group=sus
------------------
Test:
1. output of ip link
tap-test: tap pi one_queue UNKNOWN_FLAGS:900 user 1000 group 1000
id:
uid=1000(sus) gid=10(wheel) groups=10(wheel),1000(sus)
context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
Modifications:
Added:
1. file networkd-tuntap.c
3. netdev kind NETDEV_KIND_TUN and NETDEV_KIND_TAP
2. Tun and Tap Sections and config params to parse
conf and gperf conf parameters
[tomegun: tweak the 'kind' checking for received ifindex]

This new tool is based on "sd-path", a new (so far unexported) API for
libsystemd, that can hopefully grow into a workable API covering /opt
and more one day.

Instead of adjusting job timeouts in the core, let fstab-generator
write out a dropin snippet with the appropriate JobTimeout.
x-systemd-device.timeout option is removed from Options= line
in the generated unit.
The functions to write dropins are moved from core/unit.c to
shared/dropin.c, to make them available outside of core.
generator.c is moved to libsystemd-label, because it now uses
functions defined in dropin.c, which are in libsystemd-label.
|

|
|
This ways, distributions have an easier way to replace the OS specific
generic groups/users while keeping systemd's own.
|
|
When disk space taken up by coredumps grows beyond a configured limit
start removing the oldest coredump of the user with the most coredumps,
until we get below the limit again.
|
|
So that building from an archive works even if intltool is not present.
The README file already mentioned that intltool should only be required
when building from git.
Tested: Built it from the distribution archive on a host without intltool.
$ ./configure --enable-polkit
$ make

This treats it similarly to networkd, resolved and others and it matches
what 90-systemd.preset does.

This allows us to bootup a rootfs with a /usr directory only.
|
|
|

|
|
Should make the transition easier for exisiting users.

src/shared/async.c uses pthread so it will fail at link time if we link
only to libsystemd-shared and use async

Running "make dist" requires --enable-compat-libs since DIST_SOURCES will list
generated files such as libsystemd-daemon.c.
Tested:
$ ./configure && make && make dist
*** compat-libs must be enabled in order to make dist
make: *** [dist-check-compat-libs] Error 1
|
|
Running "make dist" requires Python support since some of the man page sources
(such as man/systemd.index.xml and man/systemd.directives.xml) are generated by
Python scripts, so break "make dist" and give an useful error message when
Python or the Python lxml module is not available.
Tested:
$ ./configure --without-python && make && make dist
*** python and python-lxml module must be installed and enabled in order to make dist
make: *** [dist-check-python] Error 1
|
|
Python support is pretty much essential to create man pages, so we should make
sure that distcheck will request it during configure.
Tested: Successfully ran "make distcheck" and confirmed --with-python was
present in the ./configure run inside the unpacked distribution directory.
|
|
File src/python-systemd/id128-constants.h is auto generated and its generation
does not require special tools, only sed. There is no point in bundling it in
the distribution archive, so let's mark it as nodist_ to have it excluded.
Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=80006
Tested: Successfully ran "make dist" after ./configure --without-python.
|
|
The sysusers.d/systemd.conf configuration file was originally introduced in
commit 1b99214789101, but it was not marked for cleanup. This caused distcheck
to complain about the file not being removed by distcleam.
Tested: Successfully ran "make distcheck" with this patchset.
|
|
|
|
If the file is not listed, then "make dist" will not include it.
Tested: "make distcheck" works after this fix is applied.
Fixes: 139b011ab81ccea1d51f09e0261a1c390115c6ff

It was incorrectly looking for a file in src/libsystemd-network/ when the file was actually deployed to src/systemd/ instead. This broke "make dist".
Tested: "make dist" works again after this patchset is applied.
Fixes: f20a35cc0d537dd4cfc1054cf7936b04a1700f3a

Makefile.am had a reference to it but it none of the sources included it.
Tested: "make dist" works again after this patchset is applied.

debug-generator can mask specific units if they are specified on the
kernel command line with systemd.mask=.
debug-generator can pull in debug-shell.service is systemd.debug-shell
is passed on the kernel command line.

Create a structure describing a DHCPv6 lease. Add internal functions
for creating a new lease and accessing the server ID, preference and
IAID. Provide functions for clearing addresses and associated timers.
External users are initially given only the capabilities of
referencing and unreferencing the lease structure.
|
|
Verify the Solicit message created by the DHCPv6 client code.
Provide local variants for detect_vm(), detect_container() and
detect_virtualization() defined in virt.h. This makes the DHCPv6
library believe it is run in a container and does not try to request
interface information from udev for the non-existing interface index
used by the test case code.
|
|
Add option appending and parsing. DHCPv6 options are not aligned, thus
the option handling code must be able to handle options starting at
any byte boundary.
Add a test case for the basic option handling.
|
|
Add test cases for basic DHCPv6 client handling, e.g. setting
interface index, mac address and attaching event loop.
|
|
Feed a Router Advertisement to the code and expect proper events
each time. The sending part is ignored, as all of it is static code
in the real dhcp_network_icmp6_send_rs() function.
|
|
Provide functions to bind the ICMPv6 socket to the approriate interface
and set multicast sending and receiving according to RFC 3493, section
5.2. and RFC 3542, sections 3. and 3.3. Filter out all ICMPv6 messages
except Router Advertisements for the socket in question according to
RFC 3542, section 3.2.
Send Router Solicitations to the all routers multicast group as
described in RFC 4861, section 6. and act on the received Router
Advertisments according to section 6.3.7.
Implement a similar API for ICMPv6 handling as is done for DHCPv4 and
DHCPv6.

Drop the "systemd-" prefix, renaming it from "systemd-coredumpctl" to
"coredumpctl".
|
|
elfutils' libdw is maintained, can read DWARF debug data and appears to
be the library of choice for generating backtraces today.
|
|
Introduce a new configuration file /etc/systemd/coredump.conf to
configure when to place coredumps in the journal and when on disk.
Since the coredumps are quite large, default to storing them only on
disk.

When an address is configured to be all zeroes, networkd will now
automatically find a locally unused network of the right size from a
list of pre-configured pools. Currently those pools are 10.0.0.0/8,
172.16.0.0/12, 192.168.0.0/16 and fc00::/7, i.e. the network ranges for
private networks. They are compiled in, but should be configurable
eventually.
This allows applying the same configuration to a large number of
interfaces with each time a different IP range block, and management of
these IP ranges is fully automatic.
When allocating an address range from the pool it is made sure the range
is not used otherwise.

make sure they are started before and stopped after any LUKS setup

this way, the "make install" will be detected as offline update on next
boot.
|
|
This is useful so that distros have something to base their own policy
of. It also useful to make sure that minimal installs always get useful
configuration in place.
