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/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 642e7fd23353e22290e3d51719fcb658dc252342 # < make -s -j 8 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 allyesconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # yes \n \| make -s -j 8 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 8 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/um/os-Linux/skas/process.c: In function 'start_idle_thread': /kisskb/src/arch/um/os-Linux/skas/process.c:613:1: warning: control reaches end of non-void function [-Wreturn-type] } ^ /kisskb/src/security/apparmor/policy_unpack.c: In function 'unpack_trans_table': /kisskb/src/security/apparmor/policy_unpack.c:498:9: warning: 'pos' may be used uninitialized in this function [-Wmaybe-uninitialized] str[pos] = ':'; ^ /kisskb/src/kernel/cgroup/cgroup-v1.c: In function 'cgroup1_mount': /kisskb/src/kernel/cgroup/cgroup-v1.c:1268:3: warning: 'root' may be used uninitialized in this function [-Wmaybe-uninitialized] percpu_ref_reinit(&root->cgrp.self.refcnt); ^ /kisskb/src/lib/lz4/lz4hc_compress.c: In function 'LZ4HC_compress_generic': /kisskb/src/lib/lz4/lz4hc_compress.c:579:1: warning: the frame size of 2144 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ WARNING: EXPORT symbol "__memcpy" [vmlinux] version generation failed, symbol will not be versioned.
