From 2681f560da427fe8bb2ccf5b49c81f356add46f1 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Fri, 15 Sep 2023 00:18:18 -0700 Subject: [PATCH] lscpu: Use 4K buffer size instead of BUFSIZ Some lines in /proc/cpuinfo can be large e.g. flags and can then truncate them in displaying them BUFSIZ can vary quite a bit e.g. glibc/linux systems its 8192 but on musl/linux and OSX its 1024, on mingW it is 256, some tests e.g. x86_64-64cpu-linux6.2.tar.gz has added really long line for cpu flags line which is greater than 1024 characters and hence this test fails on musl because lscpu -s reports truncated string Fixes x86_64-64cpu-linux6.2 tests Signed-off-by: Khem Raj s --- sys-utils/lscpu-cputype.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/sys-utils/lscpu-cputype.c b/sys-utils/lscpu-cputype.c index 3fd5f7a3c6..c8f72ab8a1 100644 --- a/sys-utils/lscpu-cputype.c +++ b/sys-utils/lscpu-cputype.c @@ -462,7 +462,9 @@ static int cpuinfo_parse_cache(struct lscpu_cxt *cxt, int keynum, char *data) int lscpu_read_cpuinfo(struct lscpu_cxt *cxt) { FILE *fp; - char buf[BUFSIZ]; + /* Used to be BUFSIZ which is small on some platforms e.g, musl, + * therefore hardcode to 4K */ + char buf[4096]; size_t i; struct lscpu_cputype *ct; struct cpuinfo_parser _pr = { .cxt = cxt }, *pr = &_pr; -- 2.47.2
