Unit that requires its own mount namespace creates a temporary directory
to implement dynamic bind mounts (org.freedesktop.systemd1.Manager.BindMountUnit).
However, this directory is never removed and they will accumulate for
each unique unit (e.g. templated units of systemd-coredump@).
Attach the auxiliary runtime directory existence to lifetime of other
"runtime" only per-unit directories.

Currently, sd-dhcp-server accepts spurious client IDs, then the leases

When the target (Where=) of a mount does not exist, systemd tries to
create it. But previously, it'd always been created as a directory. That
doesn't work if one wants to bind-mount a file to a target that doesn't
exist.

In make_credential_host_secret, the credential.secret file is generated
first as a temporary anonymous file that is later instantiated with
linkat(2). This system call requires CAP_DAC_READ_SEARCH capability
when the flag AT_EMPTY_PATH is used.
This patch check if the capability is effective, and if not uses the
alternative codepath for creating named temporary files.
Non-root users can now create per-user credentials with:
export SYSTEMD_CREDENTIAL_SECRET=$HOME/.config/systemd/credential.secret

When built with ACL support, we might be processing a tmpfiles
entry where there's no cause for us to call parse_acls_from_arg,
then we get to the end of parse_line without having ever populated
i.{acl_access, acl_default}.
Then we pass a null pointer into acl_free().

Let's pass USEC_INFINITY from sd_event_source_set_time_relative() to
sd_event_source_set_time() instead of raising EOVERFLOW.
We should raise EOVERFLOW only if your addition fails, but not if the
input already is USEC_INFINITY, since it's an entirely valid operation
to have an infinite time-out, and we should support that.

systemd uses malloc_usable_size() everywhere to use memory blocks
obtained through malloc, but that is abuse since the
malloc_usable_size() interface isn't meant for this kind of use, it is
for diagnostics only. This is also why systemd behaviour is flaky when
built with _FORTIFY_SOURCE.
One way to make this more standard (and hence safer) is to, at every
malloc_usable_size() call, also 'reallocate' the block so that the
compiler can see the larger size. This is done through a dummy
reallocator whose only purpose is to tell the compiler about the larger
usable size, it doesn't do any actual reallocation.
Florian Weimer pointed out that this doesn't solve the problem of an
allocator potentially growing usable size at will, which will break the
implicit assumption in systemd use that the value returned remains
constant as long as the object is valid. The safest way to fix that is
for systemd to step away from using malloc_usable_size() like this.

In both cases, the json string is short, so we can print it, which is useful
for diagnosing invalid data in packages. But we need escape non-printable
characters.

I went over the rest of the codebase, and it seems that other calls to
json_parse() don't have this problem.

When the user starts a program which elevates its permissions via setuid,
setgid, or capabilities set on the file, it may access additional information
which would then be visible in the coredump. We shouldn't make the the coredump
visible to the user in such cases.
Reported-by: Matthias Gerstner <mgerstner@suse.de>
This reads the /proc/<pid>/auxv file and attaches it to the process metadata as
PROC_AUXV. Before the coredump is submitted, it is parsed and if either
at_secure was set (which the kernel will do for processes that are setuid,
setgid, or setcap), or if the effective uid/gid don't match uid/gid, the file
is not made accessible to the user. If we can't access this data, we assume the
file should not be made accessible either. In principle we could also access
the auxv data from a note in the core file, but that is much more complex and
it seems better to use the stand-alone file that is provided by the kernel.
Attaching auxv is both convient for this patch (because this way it's passed
between the stages along with other fields), but I think it makes sense to save
it in general.
We use the information early in the core file to figure out if the program was
32-bit or 64-bit and its endianness. This way we don't need heuristics to guess
whether the format of the auxv structure. This test might reject some cases on
fringe architecutes. But the impact would be limited: we just won't grant the
user permissions to view the coredump file. If people report that we're missing
some cases, we can always enhance this to support more architectures.
I tested auxv parsing on amd64, 32-bit program on amd64, arm64, arm32, and
ppc64el, but not the whole coredump handling.
