From 8440506ee8945ad57f5e20e9962084d67808eb22 Mon Sep 17 00:00:00 2001 From: Chris Johns Date: Mon, 15 Jun 2015 17:42:23 +1000 Subject: Add tcpdump and libpcap. - Update the file builder generator to handle generator specific cflags and includes. The tcpdump and libpcap have localised headers and need specific headers paths to see them. There are also module specific flags and these need to be passed to the lex and yacc generators. - Add the tcpdump support. --- Makefile | 497 +- builder.py | 7 + freebsd-to-rtems.py | 38 +-

FreeBSD + * and OpenBSD let you get a description, but it's not generated by the OS, + * it's set with another ioctl that ifconfig supports; we use that to get + * a description in FreeBSD and OpenBSD, but if there is no such + * description available, it still might be nice to get some description + * string based on the device type or something such as that. + * + * In OS X, the System Configuration framework can apparently return + * names in 10.4 and later. + * + * It also appears that freedesktop.org's HAL offers an "info.product" + * string, but the HAL specification says it "should not be used in any + * UI" and "subsystem/capability specific properties" should be used + * instead and, in any case, I think HAL is being deprecated in + * favor of other stuff such as DeviceKit. DeviceKit doesn't appear + * to have any obvious product information for devices, but maybe + * I haven't looked hard enough. + * + * Using the System Configuration framework, or HAL, or DeviceKit, or + * whatever, would require that libpcap applications be linked with + * the frameworks/libraries in question. That shouldn't be a problem + * for programs linking with the shared version of libpcap (unless + * you're running on AIX - which I think is the only UN*X that doesn't + * support linking a shared library with other libraries on which it + * depends, and having an executable linked only with the first shared + * library automatically pick up the other libraries when started - + * and using HAL or whatever). Programs linked with the static + * version of libpcap would have to use pcap-config with the --static + * flag in order to get the right linker flags in order to pick up + * the additional libraries/frameworks; those programs need that anyway + * for libpcap 1.1 and beyond on Linux, as, by default, it requires + * -lnl. + * + * Do any other UN*Xes, or desktop environments support getting a + * description? + */ +int +add_addr_to_iflist(pcap_if_t **alldevs, const char *name, u_int flags, + struct sockaddr *addr, size_t addr_size, + struct sockaddr *netmask, size_t netmask_size, + struct sockaddr *broadaddr, size_t broadaddr_size, + struct sockaddr *dstaddr, size_t dstaddr_size, + char *errbuf) +{ + pcap_if_t *curdev;
