At this point, just move the fields in their respective address-family
specific structure. We don't use it generically yet, but instead always
explicitly select IPv4 or IPv6. But this would allow to access those
fields by address-family in the future.
Often, the code paths for IPv4 and IPv6 are very similar. We should try
to unify those code paths. The main advantage of doing that, is that
we don't unintentionally end up doing different things. And of course,
it removes duplicate code.
In a first step, unify handling of the grace timeout for DHCPv4 and
DHCPv6.
We will add a property NM_NDISC_RA_TIMEOUT for which this name is better
suited. The problem is really that our convention for object properties
and signals defines have no prefix to indicate whether it's a property
or a signal.
Rename.
It is undefined behavior and can lead to crashes or memory corruption.
In practice, this only had an issue on Big Endian systems.
Fixes: fdbf4ae5e6 ('ifcfg-rh: add IPV4_DHCP_TIMEOUT key for ipv4.dhcp-timeout property')
If a function is only called once, it may not help to simplify the code
but make it more complicated. It would only simplify the code, if it
had a clear, distinct purpose. That isn't the case here. Also, the
IPv4 writer doesn't have such a function either. Drop and inline it.
This is C, we have almost no IDE support. And ctags/cscope is much more
helpful if we use unique names.
Don't use the get_dhcp_timeout() name, because that is already used in
"src/devices/nm-device.c" already. Rename.
It is redundant. Drop it.
Also, we don't need to cancel and reschedule the idle source in
nm_manager_start(). First of all, it really shouldn't be pending.
Second, contrary to a timer, when an idle source is already pending,
then the pending one will run at the right time.
The _GET_PRIVATE() macros are all implemented based on
_NM_GET_PRIVATE(). That macro tries to be more type safe and uses
_Generic() to do the right thing. Explicitly casting is not only
unnecessary, it defeats these (static) type checks.
Don't do that.
Several macros are used to define function. They had a "_STATIC" variant,
to define the function as static.
I think those macros should not try to abstract entirely what they do.
They should not accept the function scope as argument (or have two
variants per scope). This also because it might make sense to add
additional __attribute__(()) to the function. That only works, if
the macro does not pretend to *not* define a plain function.
Instead, embrace what the function does and let the users place the
function scope as they see fit.
This also follows what is already done with
static NM_CACHED_QUARK_FCN ("autoconnect-root", autoconnect_root_quark)
In all the cases, we don't want to perform locale dependent comparison.
$ sed -i 's/\<strcasecmp\>/g_ascii_\0/g' $(git grep -w -l strcasecmp -- ':(exclude)shared/systemd/' )
We frequently have code that converts a string to number/enum.
Use a preferred implementation via the NM_UTILS_STRING_TABLE_LOOKUP_DEFINE()
macro.
Also, this does binary search, so in most cases it's (slightly) faster.
Defines in our header files should all have an NM specific prefix.
Rename.
Also rename the related defines in the source file. Usually declarations
in a source file should not have an NM prefix. But here they have for
consistency.
We keep adding capabilities. Tracking them individually via boolean (or
ternary) properties is cumbersome.
Instead, use an enum NMSupplCapType and a corresponding bitmask
NMSupplCapMask. The latter can track whether a capability is detected,
detected to be absent or not detected (unknown).
We should handle features/capabilities more generically.
Add an enum type for that. It will be used next.
Also, wpa_supplicant calls this "Capabilities", not features.
Use that name.
