Attention is currently required from: flichtenheld, plaisthos. Hello plaisthos, flichtenheld, I'd like you to do a code review. Please visit http://gerrit.openvpn.net/c/openvpn/+/788?usp=email to review the following change. Change subject: sitnl: replace NLMSG_TAIL macro with nlmsg_tail() function ...................................................................... sitnl: replace NLMSG_TAIL macro with nlmsg_tail() function The NLMSG_TAIL macro never had any reason to exist, because libnl already provides a function doing exactly the same: nlmsg_tail(). Moreover, this macro was found to confuse gcc when compiling with -O3, which would result in subsequent warnings like: networking_sitnl.c:143:9: warning: writing 4 bytes into a region of size 0 [-Wstringop-overflow=] 143 | memcpy(RTA_DATA(rta), data, alen); | ^ networking_sitnl.c:101:21: note: at offset [72, 88] into destination object ‘n’ of size 16 101 | struct nlmsghdr n; | ^ (Above warnings are critical on Fedora 40 as they are turned into errors) Delete the macro, replace it with nlmsg_tail() and get rid of the warnings.
