From 84ed94323e67c9f99606fb24e8c746a0d62ab95a Mon Sep 17 00:00:00 2001 From: David Daney <ddaney@caviumnetworks.com> Date: Fri, 18 Mar 2011 10:37:23 -0700 Subject: [PATCH] MIPS: Hook up name_to_handle_at, open_by_handle_at and clock_adjtime syscalls. These system calls we recently added. 32-bit ABIs need compat handling for sys_clock_adjtime(). o32 also needs compat handling for sys_open_by_handle_at(); Signed-off-by: David Daney <ddaney@caviumnetworks.com> To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/2165/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> --- arch/mips/include/asm/unistd.h | 21 +++++++++++++++------ arch/mips/kernel/scall32-o32.S | 3 +++ arch/mips/kernel/scall64-64.S | 3 +++ arch/mips/kernel/scall64-n32.S | 3 +++ arch/mips/kernel/scall64-o32.S | 3 +++ 5 files changed, 27 insertions(+), 6 deletions(-) diff --git a/arch/mips/include/asm/unistd.h b/arch/mips/include/asm/unistd.h index 550725b881d5..d1ea5ea7802a 100644 --- a/arch/mips/include/asm/unistd.h +++ b/arch/mips/include/asm/unistd.h @@ -359,16 +359,19 @@ #define __NR_fanotify_init (__NR_Linux + 336) #define __NR_fanotify_mark (__NR_Linux + 337) #define __NR_prlimit64 (__NR_Linux + 338) +#define __NR_name_to_handle_at (__NR_Linux + 339) +#define __NR_open_by_handle_at (__NR_Linux + 340) +#define __NR_clock_adjtime (__NR_Linux + 341) /* * Offset of the last Linux o32 flavoured syscall */ -#define __NR_Linux_syscalls 338 +#define __NR_Linux_syscalls 341 #endif /* _MIPS_SIM == _MIPS_SIM_ABI32 */ #define __NR_O32_Linux 4000 -#define __NR_O32_Linux_syscalls 338 +#define __NR_O32_Linux_syscalls 341 #if _MIPS_SIM == _MIPS_SIM_ABI64 @@ -674,16 +677,19 @@ #define __NR_fanotify_init (__NR_Linux + 295) #define __NR_fanotify_mark (__NR_Linux + 296) #define __NR_prlimit64 (__NR_Linux + 297) +#define __NR_name_to_handle_at (__NR_Linux + 298) +#define __NR_open_by_handle_at (__NR_Linux + 299) +#define __NR_clock_adjtime (__NR_Linux + 300) /* * Offset of the last Linux 64-bit flavoured syscall */ -#define __NR_Linux_syscalls 297 +#define __NR_Linux_syscalls 300 #endif /* _MIPS_SIM == _MIPS_SIM_ABI64 */ #define __NR_64_Linux 5000 -#define __NR_64_Linux_syscalls 297 +#define __NR_64_Linux_syscalls 300 #if _MIPS_SIM == _MIPS_SIM_NABI32 @@ -994,16 +1000,19 @@ #define __NR_fanotify_init (__NR_Linux + 300) #define __NR_fanotify_mark (__NR_Linux + 301) #define __NR_prlimit64 (__NR_Linux + 302) +#define __NR_name_to_handle_at (__NR_Linux + 303) +#define __NR_open_by_handle_at (__NR_Linux + 304) +#define __NR_clock_adjtime (__NR_Linux + 305) /* * Offset of the last N32 flavoured syscall */ -#define __NR_Linux_syscalls 302 +#define __NR_Linux_syscalls 305 #endif /* _MIPS_SIM == _MIPS_SIM_NABI32 */ #define __NR_N32_Linux 6000 -#define __NR_N32_Linux_syscalls 302 +#define __NR_N32_Linux_syscalls 305 #ifdef __KERNEL__ diff --git a/arch/mips/kernel/scall32-o32.S b/arch/mips/kernel/scall32-o32.S index fbaabad0e6e2..66b439db91b5 100644 --- a/arch/mips/kernel/scall32-o32.S +++ b/arch/mips/kernel/scall32-o32.S @@ -586,6 +586,9 @@ einval: li v0, -ENOSYS sys sys_fanotify_init 2 sys sys_fanotify_mark 6 sys sys_prlimit64 4 + sys sys_name_to_handle_at 5 + sys sys_open_by_handle_at 3 /* 4340 */ + sys sys_clock_adjtime 2 .endm /* We pre-compute the number of _instruction_ bytes needed to diff --git a/arch/mips/kernel/scall64-64.S b/arch/mips/kernel/scall64-64.S index 3f4179283207..0ccd6e363b79 100644 --- a/arch/mips/kernel/scall64-64.S +++ b/arch/mips/kernel/scall64-64.S @@ -425,4 +425,7 @@ sys_call_table: PTR sys_fanotify_init /* 5295 */ PTR sys_fanotify_mark PTR sys_prlimit64 + PTR sys_name_to_handle_at + PTR sys_open_by_handle_at + PTR sys_clock_adjtime /* 5300 */ .size sys_call_table,.-sys_call_table diff --git a/arch/mips/kernel/scall64-n32.S b/arch/mips/kernel/scall64-n32.S index f08ece6d8acc..179d1c8dcbb2 100644 --- a/arch/mips/kernel/scall64-n32.S +++ b/arch/mips/kernel/scall64-n32.S @@ -425,4 +425,7 @@ EXPORT(sysn32_call_table) PTR sys_fanotify_init /* 6300 */ PTR sys_fanotify_mark PTR sys_prlimit64 + PTR sys_name_to_handle_at + PTR sys_open_by_handle_at + PTR compat_sys_clock_adjtime /* 6305 */ .size sysn32_call_table,.-sysn32_call_table diff --git a/arch/mips/kernel/scall64-o32.S b/arch/mips/kernel/scall64-o32.S index 78d768a3e19d..5c4e0dc52f78 100644 --- a/arch/mips/kernel/scall64-o32.S +++ b/arch/mips/kernel/scall64-o32.S @@ -543,4 +543,7 @@ sys_call_table: PTR sys_fanotify_init PTR sys_32_fanotify_mark PTR sys_prlimit64 + PTR sys_name_to_handle_at + PTR compat_sys_open_by_handle_at /* 4340 */ + PTR compat_sys_clock_adjtime .size sys_call_table,.-sys_call_table -- GitLab
