A collection of utility functions for working with SSIDs, IP addresses, Wi-Fi access points and devices, among other things.
gboolean nm_utils_is_empty_ssid (const guint8 *ssid
,gsize len
);
Different manufacturers use different mechanisms for not broadcasting the AP's SSID. This function attempts to detect blank/empty SSIDs using a number of known SSID-cloaking methods.
const char * nm_utils_escape_ssid (const guint8 *ssid
,gsize len
);
nm_utils_escape_ssid
has been deprecated since version 1.46 and should not be used in newly-written code.
This function does a quick printable character conversion of the SSID, simply replacing embedded NULLs and non-printable characters with the hexadecimal representation of that character. Intended for debugging only, should not be used for display of SSIDs.
Warning: this function uses a static buffer. It is not thread-safe. Don't use this function.
gboolean nm_utils_same_ssid (const guint8 *ssid1
,gsize len1
,const guint8 *ssid2
,gsize len2
,gboolean ignore_trailing_null
);
Earlier versions of the Linux kernel added a NULL byte to the end of the SSID to enable easy printing of the SSID on the console or in a terminal, but this behavior was problematic (SSIDs are simply byte arrays, not strings) and thus was changed. This function compensates for that behavior at the cost of some compatibility with odd SSIDs that may legitimately have trailing NULLs, even though that is functionally pointless.
char * nm_utils_ssid_to_utf8 (const guint8 *ssid
,gsize len
);
Wi-Fi SSIDs are byte arrays, they are _not_ strings. Thus, an SSID may contain embedded NULLs and other unprintable characters. Often it is useful to print the SSID out for debugging purposes, but that should be the _only_ use of this function. Do not use this function for any persistent storage of the SSID, since the printable SSID returned from this function cannot be converted back into the real SSID of the access point.
This function does almost everything humanly possible to convert the input into a printable UTF-8 string, using roughly the following procedure:
1) if the input data is already UTF-8 safe, no conversion is performed 2) attempts to get the current system language from the LANG environment variable, and depending on the language, uses a table of alternative encodings to try. For example, if LANG=hu_HU, the table may first try the ISO-8859-2 encoding, and if that fails, try the Windows-1250 encoding. If all fallback encodings fail, replaces non-UTF-8 characters with '?'. 3) If the system language was unable to be determined, falls back to the ISO-8859-1 encoding, then to the Windows-1251 encoding. 4) If step 3 fails, replaces non-UTF-8 characters with '?'.
Again, this function should be used for debugging and display purposes _only_.
gboolean nm_utils_security_valid (NMUtilsSecurityType type
,NMDeviceWifiCapabilities wifi_caps
,gboolean have_ap
,gboolean adhoc
,NM80211ApFlags ap_flags
,NM80211ApSecurityFlags ap_wpa
,NM80211ApSecurityFlags ap_rsn
);
Given a set of device capabilities, and a desired security type to check against, determines whether the combination of device, desired security type, and AP capabilities intersect.
NOTE: this function cannot handle checking security for AP/Hotspot mode;
use nm_utils_ap_mode_security_valid()
instead.

for you, you must validate the JSON yourself.

nm_utils_wifi_strength_bars (guint8 strength
);
Converts strength

strength suitable for printing to stdout.
Previous versions used to take a guess at the terminal type and possibly return a wide UTF-8 encoded string. Now it always returns a 7-bit clean strings of one to 0 to 4 asterisks. Users that actually need the functionality are encouraged to make their implementations instead.
gsize
nm_utils_hwaddr_len (int type
);
Returns the length in octets of a hardware address of type type
.
Before 1.28, it was an error to call this function with any value other than
ARPHRD_ETHER
or ARPHRD_INFINIBAND
.
char * nm_utils_hwaddr_ntoa (gconstpointer addr

);
Converts addr

GByteArray * nm_utils_hwaddr_atoba (const char *asc

if you don't want a GByteArray.
guint8 * nm_utils_hwaddr_aton (const char *asc

gboolean nm_utils_hwaddr_matches (gconstpointer hwaddr1
,gssize hwaddr1_len
,gconstpointer hwaddr2
,gssize hwaddr2_len
);
Generalized hardware address comparison function. Tests if hwaddr1
and
hwaddr2
"equal" (or more precisely, "equivalent"), with several advantages
over a simple memcmp()
:
If hwaddr1_len
or hwaddr2_len
is -1, then the corresponding address is
assumed to be ASCII rather than binary, and will be converted to binary
before being compared.
If hwaddr1
or hwaddr2
is NULL
, it is treated instead as though it was
a zero-filled buffer hwaddr1_len
or hwaddr2_len
bytes long.
If hwaddr1
and hwaddr2
are InfiniBand hardware addresses (that is, if
they are INFINIBAND_ALEN
bytes long in binary form)
then only the last 8 bytes are compared, since those are the only bytes
that actually identify the hardware. (The other 12 bytes will change
depending on the configuration of the InfiniBand fabric that the device
is connected to.)
If a passed-in ASCII hardware address cannot be parsed, or would parse to an
address larger than NM_UTILS_HWADDR_LEN_MAX
, then it will silently fail to
match. (This means that externally-provided address strings do not need to be
sanity-checked before comparing them against known good addresses; they are
guaranteed to not match if they are invalid.)
char * nm_utils_bin2hexstr (gconstpointer src
,gsize len
,int final_len
);
Converts the byte array src
into a hexadecimal string. If final_len
is
greater than -1, the returned string is terminated at that index
(returned_string[final_len] == '\0'),
GBytes *
nm_utils_hexstr2bin (const char *hex
);
Converts a hexadecimal string hex
into an array of bytes. The optional
separator ':' may be used between single or pairs of hexadecimal characters,
eg "00:11" or "0:1". Any "0x" at the beginning of hex
is ignored. hex
may not start or end with ':'.

Checks if ip
contains a valid IP address of the given family.
gboolean nm_utils_check_virtual_device_compatibility (GType virtual_type
,GType other_type
);
Determines if a connection of type virtual_type
can (in the
general case) work with connections of type other_type
.
If virtual_type
is NM_TYPE_SETTING_VLAN
, then this checks if
other_type
is a valid type for the parent of a VLAN.
If virtual_type
is a "master" type (eg, NM_TYPE_SETTING_BRIDGE
),
then this checks if other_type
is a valid type for a slave of that
master.
Note that even if this returns TRUE
it is not guaranteed that
every connection of type other_type
is
compatible with virtual_type
; it may depend on the exact
configuration of the two connections, or on the capabilities of an
underlying device driver.
