From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> [ Upstream commit da5d669e00d2c437b3f508d60add417fc74f4bb6 ] The functions tty_audit_add_data() and tty_audit_tiocsti() are local to the tty core code, and do not need to be in a "kernel-wide" header file so move them to drivers/tty/tty.h Cc: Jiri Slaby <jirislaby@xxxxxxxxxx> Link: https://lore.kernel.org/r/20210408125134.3016837-9-gregkh@xxxxxxxxxxxxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Stable-dep-of: 094fb49a2d0d ("tty: Prevent writing chars during tcsetattr TCSADRAIN/FLUSH") Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- drivers/tty/tty.h | 14 ++++++++++++++ drivers/tty/tty_audit.c | 1 + include/linux/tty.h | 10 ---------- 3 files changed, 15 insertions(+), 10 deletions(-) diff --git a/drivers/tty/tty.h b/drivers/tty/tty.h index f4cd20261e914..f131d538b62b9 100644 --- a/drivers/tty/tty.h +++ b/drivers/tty/tty.h @@ -18,4 +18,18 @@ #define tty_info_ratelimited(tty, f, ...) \ tty_msg(pr_info_ratelimited, tty, f, ##__VA_ARGS__) +/* tty_audit.c */ +#ifdef CONFIG_AUDIT +void tty_audit_add_data(struct tty_struct *tty, const void *data, size_t size); +void tty_audit_tiocsti(struct tty_struct *tty, char ch); +#else +static inline void tty_audit_add_data(struct tty_struct *tty, const void *data, + size_t size) +{ +} +static inline void tty_audit_tiocsti(struct tty_struct *tty, char ch) +{ +} +#endif + #endif diff --git a/drivers/tty/tty_audit.c b/drivers/tty/tty_audit.c index 9f906a5b8e810..9b30edee71fe9 100644 --- a/drivers/tty/tty_audit.c +++ b/drivers/tty/tty_audit.c @@ -10,6 +10,7 @@ #include <linux/audit.h> #include <linux/slab.h> #include <linux/tty.h> +#include "tty.h" struct tty_audit_buf { struct mutex mutex; /* Protects all data below */ diff --git a/include/linux/tty.h b/include/linux/tty.h index 9e3725589214e..a1a9c4b8210ea 100644 --- a/include/linux/tty.h +++ b/include/linux/tty.h @@ -731,20 +731,10 @@ static inline void n_tty_init(void) { } /* tty_audit.c */ #ifdef CONFIG_AUDIT -extern void tty_audit_add_data(struct tty_struct *tty, const void *data, - size_t size); extern void tty_audit_exit(void); extern void tty_audit_fork(struct signal_struct *sig); -extern void tty_audit_tiocsti(struct tty_struct *tty, char ch); extern int tty_audit_push(void); #else -static inline void tty_audit_add_data(struct tty_struct *tty, const void *data, - size_t size) -{ -} -static inline void tty_audit_tiocsti(struct tty_struct *tty, char ch) -{ -} static inline void tty_audit_exit(void) { } -- 2.39.2
