This doc I wrote up to help openstack developers contains useful background info on why it is important: http://wiki.openstack.org/GitCommitMessages#Structural_split_of_changes I'm also not a fan of seeing entire source files copy+paste duplicated for BSD, when it appears that >= 95% of their contents are the same as the original file. A custom BSD file is only justified if the new code shares little-to- nothing with the existing code. Otherwise just #ifdef it. Given that I'm not reviewing any part of the patch related to the new bsd_XXXX files. > diff --git a/configure.ac b/configure.ac > index a695e52..0467a2a 100644 > --- a/configure.ac > +++ b/configure.ac > @@ -360,10 +360,11 @@ dnl are also linux specific.

We should have an enum for valid arches, and then APIs to convert to/from the OS specific values as needed. As it is today, there are too many places checks specific arch strings in the code and it is easy for us to miss one that is relevant when porting to BSD. I won't make you do that work.

NB, it is preferrable to run 'make syntax-check' before submitting any patches to identify problems like this. I know this probably isn't possible on a BSD host, but you can at least run it on a Linux host - make syntax-check doesn't required that the BSD code is compiled - it is static analysis directly on the source. > + > + return ret; > +} > #else > int virNetDevSetMAC(const char *ifname, > const virMacAddrPtr macaddr ATTRIBUTE_UNUSED) > @@ -350,6 +430,34 @@ cleanup: > VIR_FORCE_CLOSE(fd); > return ret; > } > +#elif defined(__FreeBSD__) > +int virNetDevGetMTU(const char *ifname) > +{ > + int s; > + int ret; > + struct ifreq ifr; > + > + if ((s = socket(AF_INET, SOCK_DGRAM, 0)) < 0) { > + return -1; Missing virReportSystemError() > + } > + > + ifr.ifr_addr.sa_family = AF_INET; > + strcpy(ifr.ifr_name, ifname); > + if (ioctl(s, SIOCGIFMTU, (caddr_t)&ifr) < 0) { > + virReportSystemError(errno, > + _("Cannot get interface MTU on '%s'"), > + ifname); > + goto cleanup; > + } > + > + ret = ifr.ifr_mtu; > + > + ret = 0; > + > +cleanup: > + close(s); > + return ret; > +} > #else > int virNetDevGetMTU(const char *ifname) > { > @@ -396,6 +504,34 @@ cleanup: > VIR_FORCE_CLOSE(fd); > return ret; > } > +#elif defined(__FreeBSD__) > +int virNetDevSetMTU(const char *ifname, int mtu) > +{ > + int s; > + int ret; > + struct ifreq ifr; > + > + if ((s = socket(AF_INET, SOCK_DGRAM, 0)) < 0) { > + return -1; Missing virReportSystemError > + } > + > + ifr.ifr_addr.sa_family = AF_INET; > + strcpy(ifr.ifr_name, ifname); > + ifr.ifr_mtu = mtu; > + > + if (ioctl(s, SIOCGIFMTU, (caddr_t)&ifr) < 0) { > + virReportSystemError(errno, > + _("Cannot get interface MTU on '%s'"), > + ifname); > + goto cleanup; > + } > + > + ret = 0; > + > +cleanup: > + close(s); > + return ret; > +} > #else > int virNetDevSetMTU(const char *ifname, int mtu ATTRIBUTE_UNUSED) > { > @@ -558,6 +694,50 @@ cleanup: > VIR_FORCE_CLOSE(fd); > return ret; > } > +#elif defined(__FreeBSD__) > +int virNetDevSetOnline(const char *ifname, > + bool online) > +{ > + int s; > + int ret = -1; > + int ifflags; > + > + VIR_WARN("%s, ifname = %s", __func__, ifname); > + > + struct ifreq ifr; > + memset(&ifr, 0, sizeof(ifr)); > + strlcpy(ifr.ifr_name, ifname, sizeof(ifr.ifr_name)); Use virStrncpy instead > + > + s = socket(AF_LOCAL, SOCK_DGRAM, 0); Missing check for failure > + > + if (ioctl(s, SIOCGIFFLAGS, &ifr) < 0) { > + virReportSystemError(errno, > + _("Cannot get interface flags on '%s'"), > + ifname); > + goto cleanup; > + } > + > + if (online) > + ifflags = ifr.ifr_flags | IFF_UP; > + else > + ifflags = ifr.ifr_flags & ~IFF_UP; > + > + if (ifr.ifr_flags != ifflags) { > + ifr.ifr_flags = ifflags; > + if (ioctl(s, SIOCSIFFLAGS, &ifr) < 0) { > + virReportSystemError(errno, > + _("Cannot set interface flags on '%s'"), > + ifname); > + goto cleanup; > + } > + } > + > + ret = 0; > + > +cleanup: > + close(s); > + return ret; > +} > #else > int virNetDevSetOnline(const char *ifname, > bool online ATTRIBUTE_UNUSED) > @@ -604,6 +784,36 @@ cleanup: > VIR_FORCE_CLOSE(fd); > return ret; > } > +#elif defined(__FreeBSD__) > +int virNetDevIsOnline(const char *ifname, > + bool *online) > +{ > + int s; > + int ret = -1; > + > + struct ifreq ifr; > + memset(&ifr, 0, sizeof(ifr)); > + strlcpy(ifr.ifr_name, ifname, sizeof(ifr.ifr_name)); See earlier > + > + VIR_WARN("%s, ifname = %s", __func__, ifname); > + > + s = socket(AF_LOCAL, SOCK_DGRAM, 0); See earlier > + > + if (ioctl(s, SIOCGIFFLAGS, &ifr) < 0) { > + virReportSystemError(errno, > + _("Cannot get interface flags on '%s'"), > + ifname); > + goto cleanup; > + } > + > + *online = (ifr.ifr_flags & IFF_UP) ?
