ax25_ntoa: Don't emit SSID suffix if the SSID is zero.
From: Matti Aarnio OH2MQK <matti.aarnio@zmailer.org>
In http://www.linux-ax25.org/cvsweb/libax25/axutils.c.diff?r1=1.4;r2=1.5
funtion char *ax25_ntoa(const ax25_address *a):
- *s++ = '-';
+ /* Convention is: -0 suffixes are NOT printed */
+ if (a->ax25_call[6] & 0x1E) {
+ *s++ = '-';
- if ((n = ((a->ax25_call[6] >> 1) & 0x0F)) > 9) {
- *s++ = '1';
- n -= 10;
+ if ((n = ((a->ax25_call[6] >> 1) & 0x0F)) > 9) {
+ *s++ = '1';
+ n -= 10;
+ }
+ *s++ = n + '0';
}
-
- *s++ = n + '0';
+
*s++ = '\0';
This is diametral to the previous situation, where ax25_ntoa always returned
a call with SSID.
Unfortunately, that patch broke a fixe introduced in April 2009; that patch
fixed the same issue introduced by a patch in April 2008:
http://www.linux-ax25.org/cvsweb/libax25/axconfig.c
This is a fix for a bug introduced 2008-04-02, which caused interfaces
containing CALL without SSID not being found anymore (user had to
address CALL-0 instead of just CALL).
http://www.linux-ax25.org/cvsweb/libax25/axconfig.c.diff?r1=1.7;r2=1.8
[..]
+ /* user may have configured "DL9SAU". But we compare to *ifcalls,
+ * which comes from ifr_hwaddr.sa_data and it always contains a SSID;
+ * in this case, "DL9SAU-0". This fixes a bug introduced 2008-04-02,
+ * which caused interfaces without SSID not being found anymore. :(
+ */
[..]
It has been overseen that libax25 internaly uses ax25_ntoa, not just for
user-presentation.
The fix today resolves the problem, and cleans up helper routines like
strip_zero_ssid() that are no longer needed.
Affected files: axconfig.c, nrconfig.c and procutils.c.

name of the corresponding axports line to axif, i compared axif->Name
with the device name. This matched only interfaces which are
configured as "ax0 ....." in axports, and was, indeed, not intended.

no IP-Address assigned:
Because ifc.ifc_req does not show interfaces without
IP-Address assigned, we use the device list via /proc.
This concept was inspired by net-tools / ifconfig
This feature will be enabled soon. We just need to trace down a kernel
error.
