Fixes a bug introduced by 3e4d0f6cf9.
The auxv metadata is unaligned, as the length of the prefix
"COREDUMP_PROC_AUXV=" is 19. Hence, parse_auxv{32,64}() may triger
an undefined behavior (or at least cause slow down), which can be
detected when running on an undefined behavior sanitizer.
This also introduces a macro to define `parse_auxv{32,64}()`.
Fixes#26912.
Uncompressed aarch64 and riscv64 kernels have a different startpoint than x86.
Example output from ukify:
aarch64: NotImplementedError: unknown file format (starts with b'MZ@\xfa')
riscv64: NotImplementedError: unknown file format (starts with b'MZo\x10')
Add check for (b'MZ') to catch both in one call.

Whenever we're going to close all file descriptors, we tend to close
the log and set it into open when needed mode. When this is done with
the logging target set to LOG_TARGET_AUTO, we run into issues because
for every logging call, we'll check if stderr is connected to the
journal to determine where to send the logging message. This check
obviously stops working when we close stderr, so we settle the log
target before we do that so that we keep using the same logging
target even after stderr is closed.
Suppress errors when creating/writing EFI variables during 'bootctl update' if
'--graceful' mode is active (as the documentation indicates).
Closes#26773.
Let's allow configuring tty term and size using kernel cmdline arguments
so that when running in a VM we can communicate the terminal TERM and size
from the host via SMBIOS extra kernel cmdline arguments.
Useful in combination with CHASE_PARENT to get a directory file
descriptor to the parent directory of the resolved path and the
filename of the resolved path in the parent directory (which might
not be the same as the filename of the input path because of symlinks).
The nvme by-id symlink changes to the latest namespace when a new namespace gets
added, for example by connecting multiple NVMe/TCP host controllers via nvme
connect-all.
That is incorrect for persistent device links.
The persistent symbolic device link should continue to point to the same NVMe
namespace throughout the lifetime of the current boot.
Therefore the namespace id needs to be added to the link name.
Now that we have reference counting, it's useful to be able to push
single key values onto the log context separately, so that we don't
have to allocate new storage to join the separate string together into
a single field which means we won't be able to reuse a context containing
the same field.
Let's try to optimize against pushing the same fields multiple times
onto the log context. To achieve this we make the log context reference
counted and return an existing context object if it's using the same
fields.
A consequence of this is that we have to make sure attaching/detaching
is coupled to the lifetime of the context object, so we make the attach
and detach functions private for now. If we need independent attach/detach
in the future, we can make that work with some extra complexity but since
we don't need it yet, let's not support it for now.
Fix check for conflicting and duplicate expressions of types that
support alternative patterns.
