Subject: [PATCH] Avoid relying on presence of ipx.h
After Linux has broken UAPI in commit v5.15-rc1~157^2~207, it is well
possible that neither kernel nor libc (such as musl, for example)
provides an IPX-related header. Avoid relying on its presence
in the strace's code and conditionalise the relevant checks in the tests.
* configure.ac (AC_CHECK_HEADERS): Add linux/ipx.h.
* src/net.c: Remove <netipx/ipx.h>/<linux/ipx.h> includes.
* src/sockaddr.c: Likewise.
(IPX_NODE_LEN): New macro constant.
(struct sockaddr_ipx): New type definition.
* src/xlat/sock_ipx_options.in (IPX_TYPE): Provide a fallback value.
* tests/net-sockaddr.c [!HAVE_LINUX_IPX_H]: Do not include
<linux/ipx.h>.
[!HAVE_LINUX_IPX_H && HAVE_NETIPX_IPX_H]: Include <netipx/ipx.h>.
[!(HAVE_LINUX_IPX_H || defined HAVE_NETIPX_IPX_H)] (check_ipx): Do not
define.
(main) [!(HAVE_LINUX_IPX_H || defined HAVE_NETIPX_IPX_H)]: Do not call
check_ipx.
