Instead of having 3 implementations for setting an int (int, uint, int64), combine
them. Also, make them more configurable by allowing to specify min/max/base, outside
of GParamSpec.
Returning TRUE for zero makes no sense. Obviously, zero is not a power
of two.
Also, the function is used to check whether a number has only one bit
(flag) set, so, an alternative name would be "has-one-bit-set", which
also should return FALSE for zero. All callers didn't really care for
the previous meaning "has-at-most-one-bit-set".
This also avoids the issue of checking (x >= 0), which causes
-Wtype-limits warnings for unsigned types. Which was avoided
by doing (x == 0 || x > 0), which caused -Wlogical-op warning,
which then was avoided (x == 0 || (x > 0 && 1)). Just don't.
We recently added -Wlogical-op in our build process
(commit #41e7fca59762dc928c9d67b555b1409c3477b2b0).
Seems that old versions of gcc (4.8.x) will hit that warning with our
implementation of our "nm_utils_is_power_of_two" and
"test_nm_utils_is_power_of_two_do" macros.
Fool it just adding an always TRUE check.
Use nm_device_get_ip_ifindex() to obtain the right ifindex for the

g_variant_new_parsed() returns a floating reference. Later, we pass
the floating reference to nm_settings_connection_new_secrets(),
but don't transfer ownership.
That might not be a bug (I didn't check), but it requires that
nm_settings_connection_new_secrets() does not take a reference
to the secrets variant.
Convert the floating reference to a real reference to avoid
this dangerous pattern.

We pack the PSK byte array in a GVariant of type string,
hence all characters must be valid UTF-8.
Maybe we should do something more sophisticated but let's
just ignore such pass phrases.

libnm-core.a should only be linked once in libnm.so. Previously,
it was linked twice, once as part of libnm-utils.a and once
directly in libnm.so.
Fixes: 8df944c7e4
Previously, internal parts of libnm were not testable.
Instead, add "libnm/nm-libnm-utils.c" and "libnm/libnm-utils.la"
to contain code that can be statically linked with a new
test "libnm/tests/test-general".

Remove useless check and var.

Use nm_utils_str_utf8safe_escape() to sanitize non UTF-8 sequences
before exposing them on D-Bus. The operation can be reverted client
side via nm_utils_str_utf8safe_unescape() or simply g_strcompress().
Note that this preserves all valid UTF-8 sequences as-is, with exception
of the backslash escape character and ASCII control characters. Thus, this
is a change in behavior for strings that contain such characters.
Note that nmcli is not changed to somehow unescape the string before
printing. As the string is not valid UTF-8 (or contains ASCII characters
that need escaping), they are not printable as-is, so unescaping before
printing makes little sense.
Use C-style backslash escaping to sanitize non-UTF-8 strings.
The functions are compatible with glib's g_strcompress() and
g_strescape().
The difference is only that g_strescape() escapes all non-printable,
non ASCII character as well, while nm_utils_str_utf8safe_escape()
-- depending on the flags -- preserves valid UTF-8 sequence except
backslash.
The flags allow to optionally escape ASCII control characters and
all non-ASCII (valid UTF-8) characters. But the option to preserve
valid UTF-8 (non-ASCII) characters verbatim, is what distinguishes
from g_strescape().
UDev never creates such invalid escape sequences. Anyway,
we cannot accept a NUL character at this point. Just take
the ill escape verbatim -- it should never happen anyway.
We already get a library dependency on
libnl-3.so.200()(64bit)
libnl-3.so.200(libnl_3)(64bit)
Drop the explicit package dependency, leaving only the
BuildRequires.
Also, all recent versions of libnl3 implement library versioning.
