The stub image may not have enough sections to cause enough PE header
space to be free for later expansion. Given that the stub is guaranteed
to be expanded we should always reserve enough sections for it.
This also bumps the reservation to 15. It doesn't add more space
compared to current builds but it more closely reflects the amount of
sections that a UKI could have in total if all optional sections are
used.
Fixes: #28593
The PE header size calculation failed to take the PE magic and coff
header size into account, which will lead to header truncation if we are
writing only 5 sections.
The kernel manages neighbors by the destination address, and the
LinkLayerAddress is mutable. Let's manage neighbors in the same way, and
dedup settings.
Then, we can start IPv4ACD without adding corresponding Address object
to Link.
Hopefully, no functional change, just refactoring and preparation for
later commits.
RFC4861 Neighbor Discovery – Sections 4.2 and 6.3.4
From section 4.2. Router Advertisement Message Format:
Cur Hop Limit 8-bit unsigned integer. The default value that
should be placed in the Hop Count field of the IP
header for outgoing IP packets. A value of zero
means unspecified (by this router).
If we don't have TPM support then `alg` is NULL and passing this to
table_new() means we'd get a table with only two columns instead of
three, leading up to a very confusing output:
$ build/systemd-analyze pcrs
System lacks full TPM2 support, not showing PCR state.
NR NAME
0 platform-code
- 1
platform-config -
2 external-code
- 3
external-config -
4 boot-loader-code
- 5
boot-loader-config -
6 -
- 7
...
Let's name the header in this case with a simple dash, as it's going
to be hidden anyway, to make the table nice again:
$ build/systemd-analyze pcrs
System lacks full TPM2 support, not showing PCR state.
NR NAME
0 platform-code
1 platform-config
2 external-code
3 external-config
4 boot-loader-code
5 boot-loader-config
6 -
7 secure-boot-policy
...
New meson says:
WARNING: Running the setup command as `meson [options]` instead of `meson setup [options]` is ambiguous and deprecated.
Inspired by https://github.com/systemd/systemd/issues/28482.
In many case we serialize into objects that have been zero-initialized.
To save some time and resources when there are a lot of booleans, add a
helper that serializes only when the boolean is true.
Since Linux 4.18 CONFIG_AUTOFS4_FS just enables CONFIG_AUTOFS_FS, its
description in fs/autofs/Kconfig reads:
This name exists for people to just automatically pick up the
new name of the autofs Kconfig option. All it does is select
the new option name.
It will go away in a release or two as people have
transitioned to just plain AUTOFS_FS.
