That way we can use it in nspawn.
Also, while we are at it, let's rename the call config_parse_rlimit(),
i.e. insert the "r", to clarify what kind of limit this is about.
|
|
|
|
|
| |
let's make the call more generic, so that we can also easily use it for
parsing "RLIMIT_xyz" style constants.

Configuration through environment variable is inconvenient with meson, because
they cannot be convieniently changed and/or are not preserved during
reconfiguration (https://github.com/mesonbuild/meson/issues/1503).
This adds -Dvalgrind=true/false, which has the advantage that it can be set
at any time with meson configure -Dvalgrind=... and ninja will rebuild targets
as necessary. Additional minor advantages are better consistency with the
options for hashmap debugging, and typo avoidance with '#if' instead of '#ifdef'.

If the main config file or one of the drop-ins did not have the final newline,
there would be no seperating empty line (or if this was the last file
displayed, our own output would end without the final newline, possibly running
into the subsequent prompt or such). copy_bytes() does not know anything about
lines, so let's just use a normal loop with read_line() and puts().

This implements similar logic as conf_files_cat(), but with slightly different
file gathering logic. I also want to add support for replacement files later on,
so it seems better to keep those two file-gathering functions separate.

This is used as 'systemd-analyze show-config systemd/logind.conf', which
will dump
/etc/systemd/system/user@.service
/etc/systemd/system/user@.service.d/*.conf
/run/systemd/system/user@.service.d/*.conf
/usr/local/lib/systemd/system/user@.service.d/*.conf
/usr/lib/systemd/system/user@.service.d/*.conf
The idea is to make it easy to dump the configuration using the same locations
and order that systemd programs use themselves (including masking, in the right
order, etc.). This is the generic variant that works with any configuration
scheme that follows the same general rules:
$ systemd-analyze cat-config systemd/system.conf
$ systemd-analyze cat-config systemd/user.conf
$ systemd-analyze cat-config systemd/logind.conf
$ systemd-analyze cat-config systemd/sleep.conf
$ systemd-analyze cat-config systemd/journald.conf
$ systemd-analyze cat-config systemd/journal-remote.conf
$ systemd-analyze cat-config systemd/journal-upload.conf
$ systemd-analyze cat-config systemd/coredump.conf
$ systemd-analyze cat-config systemd/resolved.conf
$ systemd-analyze cat-config systemd/timesyncd.conf
$ systemd-analyze cat-config udev/udev.conf

This fixes a buglet where the second and later drop-in would not be seperated
properly by a newline.

k was set to join_controllers at this point and only incremented, so
it cannot be null at this point.

We can jump to chase_one from two places. In the first 'todo' is set to
'buffer', which comes from path_make_absolute_cwd() and is nonnull In the
second 'todo' is set to 'joined' which is checked to be nonull a few lines
above the jump. So let's kill the code that deals with null todo there.

This makes it behave the same whether there is a blank line or not at
the end of the file. This is also consistent with the behavior of the
shell on a shell script that ends on a trailing backslash at the last
line.
Added tests to test_config_parse(), which only pass if the corresponding
change to config_parse() is included.

install_libsystemd_static
This means that when those targets are built, all the sources are built again,
instead of reusing the work done to create libbasic.a and other convenience static
libraries. It would be nice to not do this, but there seems to be no support in
our toolchain for joining multiple static libraries into one. When linking
a static library, any -l arguments are simply ignored by ar/gcc-ar, and .a
libraries given as positional arguments are copied verbatim into the archive
so they objects in them cannot be accessed.
https://stackoverflow.com/questions/2157629/linking-static-libraries-to-other-static-libraries
suggests either unzipping all the archives and putting them back togather,
or using a linker script. Unzipping and zipping back together seems ugly.
The other option is not very nice. The linker script language does not
allow "+" to appear in the filenames, and filenames that meson generates
use that, so files would have to be renamed before a linker script was used.
And we would have to generate the linker script on the fly. Either way, this
doesn't seem attractive. Since those static libraries are a niche use case,
it seems reasonable to just go with the easiest and safest solution and
recompile all the source files. Thanks to ccache, this is probably almost as
cheap as actually reusing the convenience .a libraries.
test-libsystemd-sym.c and test-libudev-sym.c compile fine with the generated
static libs, so it seems that they indeed provide all the symbols they should.

Also this makes the new `signal_from_string()` function reject
e.g, `SIG3` or `SIG+5`.
|
|
|
|
|
|
|
|
|
|

Before this, `signal_from_string()` accepts simple signal name
or RTMIN+n. This makes the function also accept RTMIN, RTMAX,
and RTMAX-n.
Note that RTMIN+0 is equivalent to RTMIN, and RTMAX-0 is to RTMAX.
This also fixes the integer overflow reported by oss-fuzz #8064.

Let's simplify the code a bit. Let's reduce the number of redundant if
checks a bit, (i.e. if we want to check for equality with
VIRTUALIZATION_VM_OTHER there's no need to check for non-equality with
VIRTUALIZATION_NONE first). As a very welcome side-effect this means we
lose some lines of code and our level of indentation is reduced.
No changes in behaviour.

Apparently Xen sometimes lies about its identity when queried via CPUID.
Let's hence prefer DMI tests for CPUID
