From 96e975a2412a20e5f80bd3ab144057d275eb8597 Mon Sep 17 00:00:00 2001 From: Chen Qi Date: Mon, 25 Feb 2019 15:12:41 +0800 Subject: [PATCH 06/22] Use uintmax_t for handling rlim_t PRIu{32,64} is not right format to represent rlim_t type therefore use %ju and typecast the rlim_t variables to uintmax_t. Fixes portablility errors like execute.c:3446:36: error: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'rlim_t {aka long long unsigned int}' [-Werror=format=] | fprintf(f, "%s%s: " RLIM_FMT "\n", | ^~~~~~~~ | prefix, rlimit_to_string(i), c->rlimit[i]->rlim_max); | ~~~~~~~~~~~~~~~~~~~~~~ Upstream-Status: Denied [https://github.com/systemd/systemd/pull/7199] Signed-off-by: Khem Raj [Rebased for v241] Signed-off-by: Chen Qi --- src/basic/format-util.h | 8 +------- src/basic/rlimit-util.c | 12 ++++++------ src/core/execute.c | 4 ++-- 3 files changed, 9 insertions(+), 15 deletions(-) diff --git a/src/basic/format-util.h b/src/basic/format-util.h index 8719df3e29..9becc96066 100644 --- a/src/basic/format-util.h +++ b/src/basic/format-util.h @@ -34,13 +34,7 @@ assert_cc(sizeof(gid_t) == sizeof(uint32_t)); # error Unknown timex member size #endif -#if SIZEOF_RLIM_T == 8 -# define RLIM_FMT "%" PRIu64 -#elif SIZEOF_RLIM_T == 4 -# define RLIM_FMT "%" PRIu32 -#else -# error Unknown rlim_t size -#endif +#define RLIM_FMT "%ju" #if SIZEOF_DEV_T == 8 # define DEV_FMT "%" PRIu64 diff --git a/src/basic/rlimit-util.c b/src/basic/rlimit-util.c index c1f0b2b974..61c5412582 100644 --- a/src/basic/rlimit-util.c +++ b/src/basic/rlimit-util.c @@ -44,7 +44,7 @@ int setrlimit_closest(int resource, const struct rlimit *rlim) { fixed.rlim_max == highest.rlim_max) return 0; - log_debug("Failed at setting rlimit " RLIM_FMT " for resource RLIMIT_%s.
