This reverts commits 89e73ce86f and
543d2a4d45.
The commit assign "custom" to fixed DUID type 5. When making DUID fully
configurable, the type number should be also configurable. Also, the
fully custom DUID should be acceptable for DHCPv4.
We went back-and-forth a bit on this. Very old meson would print a message
about detecting the program if a quoted argument was used, leading to a lot of
noise. So we started to convert various places to use the variable, but then it
turned out that meson < 0.56.2 doesn't handle this correctly and we reverted to
using strings everywhere in 7c22f07cbd. Then at
some point we stopped supporting old meson and over time we started using the
variable in various places again, somewhat inconsistently. Then most calls to
'sh' were removed in 9289e093ae when
install_emptydir() builtin started being used.
Now meson allows either the string or variable to be used, and doesn't print a
message if the string is used. Let's use the variable everywhere. For 'sh', we
could do either, but for other variables, we _do_ want the detection to happen,
for example for git, find, awk, which might not be installed and we want to
detect that early, before we start the build. It would be ugly to use quotes
for some programs, but not for others. Also, a string is still refused for
test(), so we couldn't use the string version even if we didn't care about
detection.
Parametrize table and set names for fw_nftables_add_masquerade_internal, rename
to nft_set_element_op_iprange to reflect more general usage. Export and use
nfproto_is_valid().
Remove also unused and obsolete NFPROTO_DECNET.
Now that we use meson feature options for our dependencies, we can just
rely on '--auto-features=disabled' to do the same. One benefit of this
is that specific features can still be force-enabled by overriding it
with the appropriate '-Dfeature=enabled' flag.
The two remaining uses for skip-deps can simply rely on their default
logic that sets the value to 'no' when the dependency is disabled.
Also, there is no need to conditionalize the get_variable() calls
because not-found dependencies will just return the passed default value
if provided.
This uses a two-step approach to make sure we can fall back to
find_library(), while also skipping the detection if the features are
explicitly disabled.
By making this a disabler dependency, we can slightly simplify the code
and it als fixes the build for -Dfdisk=disabled as we failed to create a
fallback empty libshared_fdisk variable.
By using meson features we can replace the handcrafted dependency
auto-detection by just passing the value from get_option directly to the
required arg for dependency, find_library etc.
'auto' features make the dependency optional, 'enabled' requires it
while 'disabled' features will skip detection entirely.
Any skipped or not found dependency will just be a no-op when passed to
build steps and therefore we can also skip the creation of empty vars.
The use of skip_deps for these is dropped here as meson provides a way
to disable all optional features in one go by passing
'-Dauto_features=disabled'.
Include T1 and T2 DHCPv6 options to expose in dbus API.
Introduced new field DHCPv6lease where these options are
added. This will be added to the JSON output when we query
org.freedesktop.network1.Manager object.
A Lifetime of 0 indicates that the router is not a default router anymore
and associated default route should be discarded from host's routing table.
https://datatracker.ietf.org/doc/html/rfc4861
```
Router Lifetime
16-bit unsigned integer. The lifetime associated
with the default router in units of seconds. The
field can contain values up to 65535 and receivers
should handle any value, while the sending rules in
Section 6 limit the lifetime to 9000 seconds. A
Lifetime of 0 indicates that the router is not a
default router and SHOULD NOT appear on the default
router list. The Router Lifetime applies only to
the router's usefulness as a default router; it
does not apply to information contained in other
message fields or options. Options that need time
limits for their information include their own
lifetime fields.

Previously, mount_private_sysfs() was implemented by using open_tree()
and move_mount() to keep submounts. But these syscalls are slightly new
and supported since kernel version 5.2.
We already do the same thing for /proc/, but without the new syscalls.
Let's use the same logic to mount private procfs. Then, we can mount
new instance of sysfs with older kernels.
- add reference to the service unit in the man page,
- fix several indentation and typos,
- replace '(uint64_t) -1' with 'UINT64_MAX',
- drop unnecessary 'continue'.
- rename TCPRetransmissionTimeOutSec= -> TCPRetransmissionTimeoutSec,
- refuse infinity,
- fix the input value verifier (USEC_PER_SEC -> USEC_PER_MSEC),
- use DIV_ROUND_UP() when assigning the value.
Follow-ups for 1412d4a4fe.
Closes#28898.
The kernel default for tmpfs mounts is rwxrwxrwt, i.e. world-writable with the
sticky bit set. This makes sense for /tmp and /var/tmp, but less so for other
directories. Users will not use systemd-mount to mount /tmp and /var/tmp, so
the existing behaviour is surprising. The defaults are overriden to the
same defaults we use for "internal tmpfs mounts", i.e. no sticky bit, nosuid,
nodev, and limits of size=10%, nr_inodes=400k.
--tmpfs is new, so we can modify the behaviour without breaking compatibility.
