+
+Fixes several warnings when compiling under musl, e.g.
+
+ui/irqbalance-ui.c: In function 'create_credentials_msg':
+ui/irqbalance-ui.c:32:2: warning: implicit declaration of function 'memset' [-Wimplicit-function-declaration]
+  memset(msg, 0, sizeof(struct msghdr));
+  ^~~~~~
+ui/irqbalance-ui.c:32:2: warning: incompatible implicit declaration of built-in function 'memset'
+ui/irqbalance-ui.c:32:2: note: include '<string.h>' or provide a declaration of 'memset'
+ui/irqbalance-ui.c: In function 'init_connection':
+ui/irqbalance-ui.c:49:2: warning: incompatible implicit declaration of built-in function 'memset'

+Subject: [PATCH 2/3] Fix struct msghdr initialization
+
+musl defines struct msghdr with padding fields to be strictly
+POSIX compliant. The current code gives following warnings:
+
+irqbalance.c: In function 'sock_handle':
+irqbalance.c:333:42: warning: initialization makes integer from pointer without a cast [-Wint-conversion]
+  struct msghdr msg = { NULL, 0, &iov, 1, NULL, 0, 0 };
+                                          ^~~~
+irqbalance.c:333:42: note: (near initialization for 'msg.__pad1')
+irqbalance.c:333:9: warning: missing initializer for field '__pad2' of 'struct msghdr' [-Wmissing-field-initializers]
+  struct msghdr msg = { NULL, 0, &iov, 1, NULL, 0, 0 };
+         ^~~~~~
+In file included from /usr/include/sys/socket.h:20:0,
+                 from /usr/include/fortify/sys/socket.h:20,
+                 from irqbalance.c:34:
+/usr/include/bits/socket.h:7:28: note: '__pad2' declared here
+  socklen_t msg_controllen, __pad2;
+                            ^~~~~~
+
+Fix this by not relying on field ordering. Alternatively
+designated initializers could be used, but as they are not
+used elsewhere in the code, I used explicit assignments.
