From 54d38a5ca0f7d1c70af5c0ccfba3b1eb3f8926b1 Mon Sep 17 00:00:00 2001 From: Hangbin Liu Date: Fri, 15 Mar 2024 10:34:43 +0800 Subject: [PATCH] scripts/bpf_doc: Use silent mode when exec make cmd [ Upstream commit 5384cc0d1a88c27448a6a4e65b8abe6486de8012 ] When getting kernel version via make, the result may be polluted by other output, like directory change info. e.g. $ export MAKEFLAGS="-w" $ make kernelversion make: Entering directory '/home/net' 6.8.0 make: Leaving directory '/home/net' This will distort the reStructuredText output and make latter rst2man failed like: [...] bpf-helpers.rst:20: (WARNING/2) Field list ends without a blank line; unexpected unindent. [...] Using silent mode would help. e.g. $ make -s --no-print-directory kernelversion 6.8.0 Fixes: fd0a38f9c37d ("scripts/bpf: Set version attribute for bpf-helpers(7) man page") Signed-off-by: Michael Hofmann Signed-off-by: Hangbin Liu Signed-off-by: Daniel Borkmann Reviewed-by: Quentin Monnet Acked-by: Alejandro Colomar Link: https://lore.kernel.org/bpf/20240315023443.2364442-1-liuhangbin@gmail.com Signed-off-by: Sasha Levin --- scripts/bpf_doc.py | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/scripts/bpf_doc.py b/scripts/bpf_doc.py index 0669bac5e900..3f899cc7e99a 100755 --- a/scripts/bpf_doc.py +++ b/scripts/bpf_doc.py @@ -414,8 +414,8 @@ class PrinterRST(Printer): version = version.stdout.decode().rstrip() except: try: - version = subprocess.run(['make', 'kernelversion'], cwd=linuxRoot, - capture_output=True, check=True) + version = subprocess.run(['make', '-s', '--no-print-directory', 'kernelversion'], + cwd=linuxRoot, capture_output=True, check=True) version = version.stdout.decode().rstrip() except: return 'Linux'
