For example: + + 35: 0000000000000838 96 FUNC LOCAL DEFAULT [: 8] 1 btf_is_struct + +The extra "[: 8]" prevents the GLOBAL_SYM_COUNT variable to +be computed correctly and causes the check_abi target to fail. + +Fix that by looking for the symbol name in the last field instead of the +8th one. This way it should also cope with future extra fields. + +Signed-off-by: Aurelien Jarno +Signed-off-by: Daniel Borkmann +Tested-by: Michael Ellerman +Link: https://lore.kernel.org/bpf/20191201195728.4161537-1-aurelien@aurel32.net +--- + tools/lib/bpf/Makefile | 4 ++-- + 1 file changed, 2 insertions(+), 2 deletions(-) + +diff --git a/tools/lib/bpf/Makefile b/tools/lib/bpf/Makefile +index 37d7967aa166..3d3d024f7b94 100644 +--- a/tools/lib/bpf/Makefile ++++ b/tools/lib/bpf/Makefile +@@ -147,7 +147,7 @@ TAGS_PROG := $(if $(shell which etags 2>/dev/null),etags,ctags) + + GLOBAL_SYM_COUNT = $(shell readelf -s --wide $(BPF_IN_SHARED) | \ + cut -d "@" -f1 | sed 's/_v[0-9]_[0-9]_[0-9].*//' | \ +- awk '/GLOBAL/ && /DEFAULT/ && !/UND/ {print $$8}' | \ ++ awk '/GLOBAL/ && /DEFAULT/ && !/UND/ {print $$NF}' | \ + sort -u | wc -l) + VERSIONED_SYM_COUNT = $(shell readelf -s --wide $(OUTPUT)libbpf.so | \ + grep -Eo '[^ ]+@LIBBPF_' | cut -d@ -f1 | sort -u | wc -l) +@@ -216,7 +216,7 @@ check_abi: $(OUTPUT)libbpf.so + "versioned in $(VERSION_SCRIPT)." >&2; \ + readelf -s --wide $(BPF_IN_SHARED) | \ + cut -d "@" -f1 | sed 's/_v[0-9]_[0-9]_[0-9].*//' | \ +- awk '/GLOBAL/ && /DEFAULT/ && !/UND/ {print $$8}'| \ ++ awk '/GLOBAL/ && /DEFAULT/ && !/UND/ {print $$NF}'| \ + sort -u > $(OUTPUT)libbpf_global_syms.tmp; \ + readelf -s --wide $(OUTPUT)libbpf.so | \ + grep -Eo '[^ ]+@LIBBPF_' | cut -d@ -f1 | \ +-- +2.23.0 + diff --git a/kernel-tools.spec b/kernel-tools.spec index 85ab5ca..c46c3c0 100644 --- a/kernel-tools.spec +++ b/kernel-tools.spec @@ -109,6 +109,10 @@ Patch0: 0001-iio-Use-event-header-from-kernel-tree.patch # rpmlint cleanup Patch6: 0002-perf-Don-t-make-sourced-script-executable.patch + +# Should be fixed upstream soon +Patch7: 0001-libbpf-Fix-readelf-output-parsing-on-powerpc-with-re.patch + Name: kernel-tools Summary: Assortment of tools for the Linux kernel License: GPLv2 @@ -215,6 +219,7 @@ cd linux-%{kversion} %patch0 -p1 %patch6 -p1 +%patch7 -p1 -R # END OF PATCH APPLICATIONS
