Support filtering by ip protocol (L4) in SocketBind{Allow|Deny}=
properties.
The signature of dbus methods must be finalized before new release is
cut, hence reserve a parameter for ip protocol.
Implementation will follow.
Closes https://github.com/systemd/systemd/issues/19891
The logic is that if the options are updated after boot, we *don't* use
the new value. But we still want to print out the changed contents in
bootctl as to not confuse people.
Fixes#19597.
Also https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=988450.
$ build/bootctl systemd-efi-options
quiet
Note: SystemdOptions EFI variable has been modified since boot. New value: debug
The hint is printed to stderr, so scripts should not be confused.
Creating those string dynamically at runtime is slow and unnecessary.
Let's use static strings with a bit of macro magic and the let the compiler
coalesce as much as possible.
$ size build/src/shared/libsystemd-shared-248.so{.old,}
text data bss dec hex filename

A nice side-effect is that the same form is used everywhere, so it's easier to
figure out all variables that are used, and where each specific variable is
used.
C.f. 2b0445262a.
Note: 'const char *foo = alloca(…);' seems OK. Our coding style document and
alloca(3) only warn against using alloca() in function invocations. Declaring
both stack variable and alloca at the same time should be fine: no matter in
which order they happen, i.e. if the pointer variable is above the contents,
or the contents are above the pointer, or even if the pointer is elided by the
compiler, everything should be fine.
In the light of https://lwn.net/Articles/859679/ let's drop
quotactl_path() again from the filter set list, as it got backed out
again in 5.13-rc3.
It's likely going to be replaced by quotactl_fd() eventually, but that
hasn't made its way into the tree yet, hence let's not replace the entry
for now.
This partially reverts 34254e599a.
So in theory UUID Variant 2 (i.e. microsoft GUIDs) are supposed to be
displayed in native endian. That is of course a bad idea, and Linux
userspace generally didn't implement that, i.e. uuidd and similar.
Hence, let's not bother either, but let's document that we treat
everything the same as Variant 1, even if it declares something else.
Previously, when `link_request_queue()` is called in link_request_set_link(),
`SetLinkOperation` is casted with INT_TO_PTR(), and the value is assigned to
`void *object`. However the value was read directly through the member
`SetLinkOperation set_link_operation` of the union which `object`
beloging to. Thus, read value was always 0 on big-endian systems.
Fixes configuring link issue on s390x systems.
Debugging udev issues especially during the early boot is fairly
difficult. Currently, you need to enable (at least) debug logging and
start monitoring uevents, try to reproduce the issue and then analyze
and correlate two (usually) huge log files. This is not ideal.
This patch aims to provide much more focused debugging tool,
tracepoints. More often then not we tend to have at least the basic idea
about the issue we are trying to debug further, e.g. we know it is
storage related. Hence all of the debug data generated for network
devices is useless, adds clutter to the log files and generally
slows things down.
Using this set of tracepoints you can start asking very specific
questions related to event processing for given device or subsystem.
Tracepoints can be used with various tracing tools but I will provide
examples using bpftrace.
Another important aspect to consider is that using tracepoints you can
debug production systems. There is no need to install test packages with
added logging, no debuginfo packages, etc...
Example usage (you might be asking such questions during the debug session),
Q: How can I list all tracepoints?
A: bpftrace -l 'usdt:/usr/lib/systemd/systemd-udevd:udev:*'
Q: What are the arguments for each tracepoint?
A: Look at the code and search for use of DEVICE_TRACE_POINT macro.
Q: How many times we have executed external binary?
A: bpftrace -e 'usdt:/usr/lib/systemd/systemd-udevd:udev:spawn_exec { @cnt = count(); }'
Q: What binaries where executed while handling events for "dm-0" device?
A bpftrace -e 'usdt:/usr/lib/systemd/systemd-udevd:udev:spawn_exec / str(arg1) == "dm-0"/ { @cmds[str(arg4)] = count(); }'
Thanks to Thomas Weißschuh <thomas@t-8ch.de> for reviewing this patch
and contributions that allowed us to drop the dependency on dtrace tool
and made the resulting code much more concise.
This reverts commit 592d419ce6.
The commit makes journald unstable, and is just an optimization
for the size of journal. Hence, it is safe to revert the commit.
Fixes#19895.
The previous string was "unknown", but that's wrong, because we *do*
know what we are going to do with those partitions: we leave them
unmodified, hence say "unchanged" in the output, to be clearer.
The currently hardcoded value works with the default configuration, but
breaks when QEMU_MEM != 512M (in sanitizer runs, for example).
```
# QEMU_MEM=1G make -C test/TEST-36-NUMAPOLICY/ run
make: Entering directory '/home/fsumsal/repos/@systemd/systemd/test/TEST-36-NUMAPOLICY'

qemu-kvm: total memory for NUMA nodes (0x20000000) should equal RAM size (0x40000000)
E: QEMU failed with exit code 1
