This # means that only those parameters which are actually needed for a # specific syscall are passed on during syscall entry, instead of # filling in six CPU registers with random user space content all the # time (which may cause serious trouble down the call chain). Those # x86-specific patches will be pushed through the x86 tree in the near # future. # # Moreover, rules on how data may be accessed may differ between kernel # data and user data. This is another reason why calling sys_xyzzy() is # generally a bad idea, and -- at most -- acceptable in arch-specific # code. # # This patchset removes all in-kernel calls to syscall functions in the # kernel with the exception of arch/. On top of this, it cleans up the # three places where many syscalls are referenced or prototyped, namely # kernel/sys_ni.c, include/linux/syscalls.h and include/linux/compat.h" # # * 'syscalls-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux: (109 commits) # bpf: whitelist all syscalls for error injection # kernel/sys_ni: remove {sys_,sys_compat} from cond_syscall definitions # kernel/sys_ni: sort cond_syscall() entries # syscalls/x86: auto-create compat_sys_() prototypes # syscalls: sort syscall prototypes in include/linux/compat.h # net: remove compat_sys_() prototypes from net/compat.h # syscalls: sort syscall prototypes in include/linux/syscalls.h # kexec: move sys_kexec_load() prototype to syscalls.h # x86/sigreturn: use SYSCALL_DEFINE0 # x86: fix sys_sigreturn() return type to be long, not unsigned long # x86/ioport: add ksys_ioperm() helper; remove in-kernel calls to sys_ioperm() # mm: add ksys_readahead() helper; remove in-kernel calls to sys_readahead() # mm: add ksys_mmap_pgoff() helper; remove in-kernel calls to sys_mmap_pgoff() # mm: add ksys_fadvise64_64() helper; remove in-kernel call to sys_fadvise64_64() # fs: add ksys_fallocate() wrapper; remove in-kernel calls to sys_fallocate() # fs: add ksys_p{read,write}64() helpers; remove in-kernel calls to syscalls # fs: add ksys_truncate() wrapper; remove in-kernel calls to sys_truncate() # fs: add ksys_sync_file_range helper(); remove in-kernel calls to syscall # kernel: add ksys_setsid() helper; remove in-kernel call to sys_setsid() # kernel: add ksys_unshare() helper; remove in-kernel calls to sys_unshare() # ... # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < git log --format=%s --max-count=1 642e7fd23353e22290e3d51719fcb658dc252342 # < make -s -j 10 ARCH=sh O=/kisskb/build/linus_sh7710voipgw_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- sh7710voipgw_defconfig # make -s -j 10 ARCH=sh O=/kisskb/build/linus_sh7710voipgw_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1317:2: warning: #warning syscall pkey_mprotect not implemented [-Wcpp] <stdin>:1320:2: warning: #warning syscall pkey_alloc not implemented [-Wcpp] <stdin>:1323:2: warning: #warning syscall pkey_free not implemented [-Wcpp] <stdin>:1326:2: warning: #warning syscall statx not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh3/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh3/../../entry-common.S:389: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh3/../../entry-common.S:392: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/clock-cpg.c: In function 'cpg_clk_init': /kisskb/src/arch/sh/kernel/cpu/clock-cpg.c:53:3: warning: 'arch_init_clk_ops' is deprecated (declared at /kisskb/src/arch/sh/include/asm/clock.h:8) [-Wdeprecated-declarations] /kisskb/src/arch/sh/kernel/cpu/clock-cpg.c: In function 'arch_clk_init': /kisskb/src/arch/sh/kernel/cpu/clock-cpg.c:77:2: warning: 'cpg_clk_init' is deprecated (declared at /kisskb/src/arch/sh/kernel/cpu/clock-cpg.c:47) [-Wdeprecated-declarations] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/sh/clk/cpg.c: In function 'r8': /kisskb/src/drivers/sh/clk/cpg.c:41:2: warning: passing argument 1 of 'ioread8' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:29:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r16': /kisskb/src/drivers/sh/clk/cpg.c:46:2: warning: passing argument 1 of 'ioread16' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:30:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r32': /kisskb/src/drivers/sh/clk/cpg.c:51:2: warning: passing argument 1 of 'ioread32' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:32:21: note: expected 'void ' but argument is of type 'const void ' Kernel: arch/sh/boot/zImage is ready Completed OK # rm -rf /kisskb/build/linus_sh7710voipgw_defconfig_sh4 # Build took: 0:00:31.970637
