We have this ids, hence let's use them universally.

After all, it is pretty generic, has no external deps besides libc, and is very
similar to virt.[ch] which is also in basic/

missing.h: Explicitly check for IFLA_BRPORT_PROXYARP
|
|
reset usec when bumping hours/minutes
|
|
RHEL explicitly disables IFLA_BRPORT_PROXYARP by renaming the enum value.
In order to support unpatched builds, we have two options:
a) redefine the enum value through missing.h and ignore the fact that it
is really unsupported, or
b) omit that enum value on rtnl_prot_info_bridge_port_types[]
As we are not actually using this netlink type anywhere, and because it
is only hooked up for the sake of completeness, this patch opts for the
former.

A fix for #2678

Make sure we propagate errors properly.

normalization success
After all, we verify that every calendar part is not out of bounds later on,
and it's fully OK if the normalization has no effect.

Let's add some minimalistic LLDP sender support. The idea is that this is
either on or off, and all fields determined automatically rather than
configured explicitly.

Let's not get confused should we be connected to some bridge that mirrors back
our packets.

Usually, we place the #pragma once before the copyright blurb in header files,
but in a few cases we didn't. Move those around, so that we do the same thing
everywhere.
|
|
After all, most ETHERTYPE variables are defined in the system headers, hence
define these where we defined all other fill-ins for system headers.

gcc thinks that multiplier might be unitialized. Split out the inner

alloc-util: extract overflow check into inline function
|
|
This patch contains a set of little cleanups for alloc-util.h:
1. The malloc_multiply(), realloc_multiply() and memdup_multiply()
functions check allocation related parameters on overflow. Let's
move them to the separate size_multiply_overflow() function for
simplicity, code duplication prevention and possible reuse in future.
2. use SIZE_MAX from stdlib instead of ((size_t) - 1) to be more
clear.
3. The 'a'/'b' variables are renamed to 'size' and 'need' to be
more clear.'

resolve: dumping of binary packets
|
|
When the buffer is allocated on the stack we do not have to check for
failure everywhere. This is especially useful in debug statements, because
we can put dns_resource_key_to_string() call in the debug statement, and
we do not need a seperate if (log_level >= LOG_DEBUG) for the conversion.
dns_resource_key_to_string() is changed not to provide any whitespace
padding. Most callers were stripping the whitespace with strstrip(),
and it did not look to well anyway. systemd-resolve output is not column
aligned anymore.
The result of the conversion is not stored in DnsTransaction object
anymore. It is used only for debugging, so it seems fine to generate it
when needed.
Various debug statements are extended to provide more information.

Networkd, resolved, build-sys fixes

networkd: FIONREAD is not reliable on some sockets
|

Before this patch existence of char16_t, char32_t, key_serial_t was checked
with AC_CHECK_DECLS() which doesn't actually work for types. Correct this to
use AC_CHECK_TYPES() instead.
Also, while we are at it, change the check for memfd_create() to use
AC_CHECK_DECLS() instead of AC_CHECK_FUNCS(). This is a better choice, since a
couple of syscalls are defined by glibc but not exported in the header files
(pivot_root() for example), and we hence should probably be more picky with
memfd_create() too, which glibc might decide to expose one day, but not
necessarily in the headers too.

The deserialize_timestamp_value() is renamed timestamp_deserialize() to be more
consistent with dual_timestamp_deserialize()
And add the NULL check back on realtime and monotonic

time-util: introduce deserialize_timestamp_value()
|
|
The time-util.c provides dual_timestamp_deserialize() function to
convert value to usec_t and set it as value of ts->monotonic and
ts->realtime.
There are some places in code which do the same but only for one
clockid_t (realtime or monotonic), when dual_timestamp_deserialize()
sets value of both.
This patch introduces the deserialize_timestamp_value() which converts
a given value to usec_t and write it to a given timestamp.

Move activate to bin, extend --fdnames functionality

We already define IFLA_PROMISCUITY and some other of these masks in
order to allow building with older headers. Define IFLA_EXT_MASK too,
which was added in the same kernel version as IFLA_PROMISCUITY (v3.10).

Empty strings were ignored in strv_join, but only if they were at the beginning
of the string. Empty strings after at least one non-empty item were treated
normally.
Previously:
{"x"} → "x"
{"x", ""} → "x"
{"x", "", ""} → "x::"
{""} → ""
{"", ""} → ""
{"", "", ""} → ""
{"", "x"} → "x"
{"", "x", ""} → "x:"
Now:
{"x"} → "x"
{"x", ""} → "x"
{"x", "", ""} → "x::"
{""} → ""
{"", ""} → ":"
{"", "", ""} → "::"
{"", "x"} → ":x"
{"", "x", ""} → ":x:"

Some spring cleaning

let's export as little as we can

The dir is not used otherwise, hence let's drop the Makefile, so that the dir
stops to exist, too.

This was used by the dkr logic, which is gone now, hence remove this too.
Should we need it one day again the git history never forgets...
Note that this only covers the JSON parser. The JSON generator used by
"journalctl -o json" remains, as its much much simpler and requires no
infrastructure except printf() and the most basic escaping.

Better support of OPENPGPKEY, CAA, TLSA packets and tests

This feature will not be used anytime soon, so remove a bit of cruft.
The BusPolicy= config directive will stay around as compat noop.

ISO/IEC 9899:1999 §7.21.1/2 says:
Where an argument declared as size_t n specifies the length of the array
for a function, n can have the value zero on a call to that
function. Unless explicitly stated otherwise in the description of a
particular function in this subclause, pointer arguments on such a call
shall still have valid values, as described in 7.1.4.
In base64_append_width memcpy was called as memcpy(x, NULL, 0). GCC 4.9
started making use of this and assumes This worked fine under -O0, but
does something strange under -O3.
This patch fixes a bug in base64_append_width(), fixes a possible bug in
journal_file_append_entry_internal(), and makes use of the new function
to simplify the code in other places.

cgroup: remove support for NetClass= directive
|
|
Support for net_cls.class_id through the NetClass= configuration directive
has been added in v227 in preparation for a per-unit packet filter mechanism.
However, it turns out the kernel people have decided to deprecate the net_cls
and net_prio controllers in v2. Tejun provides a comprehensive justification
for this in his commit, which has landed during the merge window for kernel
v4.5:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=bd1060a1d671
As we're aiming for full support for the v2 cgroup hierarchy, we can no
longer support this feature. Userspace tool such as nftables are moving over
to setting rules that are specific to the full cgroup path of a task, which
obsoletes these controllers anyway.
This commit removes support for tweaking details in the net_cls controller,
but keeps the NetClass= directive around for legacy compatibility reasons.

This reworks the coredumping logic so that the coredump handler invoked from the kernel only collects runtime data
about the crashed process, and then submits it for processing to a socket-activate coredump service, which extracts a
stacktrace and writes the coredump to disk.
This has a number of benefits: the disk IO and stack trace generation may take a substantial amount of resources, and
hence should better be managed by PID 1, so that resource management applies. This patch uses RuntimeMaxSec=, Nice=, OOMScoreAdjust=
and various sandboxing settings to ensure that the coredump handler doesn't take away unbounded resources from normally
priorized processes.
This logic is also nice since this makes sure the coredump processing and storage is delayed correctly until
/var/systemd/coredump is mounted and writable.
Fixes: #2286
