perf beauty socket/prctl_option: Cope with extended regexp complaint by grep

2023-10-31T15:31:19Z

Noticed on fedora 38, the extended regexp that so far was ok for both grep and sed now gets complaints by grep, that says '/' doesn't need to be escaped with '\'. So stop using '/' in sed, use '%' instead and remove the \ before / in the common extended regexp.

perf tools: Use "grep -E" instead of "egrep"

2022-12-14T18:28:19Z

The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this up by moving the related file to use "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/perf` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by: Tiezhu Yang Acked-by: Ian Rogers Cc: Alexander Shishkin Cc: Jiri Olsa Cc: Mark Rutland Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lore.kernel.org/lkml/1668762999-9297-1-git-send-email-yangtiezhu@loongson.cn Signed-off-by: Arnaldo Carvalho de Melo

perf beauty socket: Add generator for socket level (SOL_*) string table

perf beauty socket: Prep to receive more input header files

Move from ternary like expression to an if block, this way we'll have just the extra lines for new files in the following patches. Signed-off-by: Arnaldo Carvalho de Melo

2021-11-12T13:40:34Z

Paving the way to pass more headers to be consumed, like tools/perf/trace/beauty/include/linux/socket.h in addition to the current tools/include/uapi/linux/in.h, to get the SOL_* defines. Signed-off-by: Arnaldo Carvalho de Melo

perf beauty: Rename socket_ipproto.sh to socket.sh to hold more socket table generators

2021-11-12T13:40:34Z

To avoid having to add new entries to tools/perf/Makefile.perf prep socket.sh so that it can generate other socket table generators, such as the upcoming SOL_ socket level one. Signed-off-by: Arnaldo Carvalho de Melo

perf beauty: Make all sockaddr files use a common naming scheme

2021-11-12T13:40:34Z

The script that generates the tables was named 'socket.sh', which is confusing, rename it to sockaddr.sh and make sure the related Makefile.perf targets also use the 'sockaddr' namespace. Signed-off-by: Arnaldo Carvalho de Melo

perf trace beauty: Add script to autogenerate socket families table

2020-08-12T11:38:36Z

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 Cc: Jiri Olsa Cc: Namhyung Kim Cc: Steven Rostedt Signed-off-by: Arnaldo Carvalho de Melo
