2023-11-22tools headers: Update tools's copy of socket.h headerNamhyung Kim
tldr; Just FYI, I'm carrying this on the perf tools tree. Full explanation: There used to be no copies, with tools/ code using kernel headers directly. From time to time tools/perf/ broke due to legitimate kernel hacking. At some point Linus complained about such direct usage. Then we adopted the current model. The way these headers are used in perf are not restricted to just including them to compile something. There are sometimes used in scripts that convert defines into string tables, etc, so some change may break one of these scripts, or new MSRs may use some different #define pattern, etc. E.g.: $ ls -1 tools/perf/trace/beauty/*.sh | head -5 tools/perf/trace/beauty/arch_errno_names.sh tools/perf/trace/beauty/drm_ioctl.sh tools/perf/trace/beauty/fadvise.sh tools/perf/trace/beauty/fsconfig.sh tools/perf/trace/beauty/fsmount.sh $ $ tools/perf/trace/beauty/fadvise.sh static const char *fadvise_advices[] = { [0] = "NORMAL", [1] = "RANDOM", [2] = "SEQUENTIAL", [3] = "WILLNEED", [4] = "DONTNEED", [5] = "NOREUSE", }; $ The tools/perf/check-headers.sh script, part of the tools/ build process, points out changes in the original files. So its important not to touch the copies in tools/ when doing changes in the original kernel headers, that will be done later, when check-headers.sh inform about the change to the perf tools hackers.

Now that ->sendpage() has been removed, MSG_SENDPAGE_NOTLAST can be cleaned up. Things were converted to use MSG_MORE instead, but the protocol sendpage stubs still convert MSG_SENDPAGE_NOTLAST to MSG_MORE, which is now unnecessary.

To use with 'perf trace', to convert the protocol families to strings, e.g: $ tools/perf/trace/beauty/socket.sh static const char *socket_families[] = { [0] = "UNSPEC", [1] = "LOCAL", [2] = "INET", [3] = "AX25", [4] = "IPX", [5] = "APPLETALK", [6] = "NETROM", [7] = "BRIDGE", [8] = "ATMPVC", [9] = "X25", [10] = "INET6", [11] = "ROSE", [12] = "DECnet", [13] = "NETBEUI", [14] = "SECURITY", [15] = "KEY", [16] = "NETLINK", [17] = "PACKET", [18] = "ASH", [19] = "ECONET", [20] = "ATMSVC", [21] = "RDS", [22] = "SNA", [23] = "IRDA", [24] = "PPPOX", [25] = "WANPIPE", [26] = "LLC", [27] = "IB", [28] = "MPLS", [29] = "CAN", [30] = "TIPC", [31] = "BLUETOOTH", [32] = "IUCV", [33] = "RXRPC", [34] = "ISDN", [35] = "PHONET", [36] = "IEEE802154", [37] = "CAIF", [38] = "ALG", [39] = "NFC", [40] = "VSOCK", [41] = "KCM", [42] = "QIPCRTR", [43] = "SMC", [44] = "XDP", }; $ This uses a copy of include/linux/socket.h that is kept in a directory to be used just for these table generation scripts and for checking if the kernel has a new file that maybe gets something new for these tables. This allows us to: - Avoid accessing files outside tools/, in the kernel sources, that may be changed in unexpected ways and thus break these scripts. - Notice when those files change and thus check if the changes don't break those scripts, update them to automatically get the new definitions, a new socket family, for instance. - Not add then to the tools/include/ where it may end up used while building the tools and end up requiring dragging yet more stuff from the kernel or plain break the build in some of the myriad environments where perf may be built. This will replace the previous static array in tools/perf/ that was dated and was already missing the AF_KCM, AF_QIPCRTR, AF_SMC and AF_XDP families. The next cset will wire this up to the perf build process. At some point this must be made into a library to be used in places such as libtraceevent, bpftrace, etc. Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
