But we haven't supported that in a long time, and these # days the 'type' argument is a purely historical artifact. # # A discussion about extending 'user_access_begin()' to do the range # checking resulted this patch, because there is no way we're going to # move the old VERIFY_xyz interface to that model. And it's best done at # the end of the merge window when I've done most of my merges, so let's # just get this done once and for all. # # This patch was mostly done with a sed-script, with manual fix-ups for # the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form. # # There were a couple of notable cases: # # - csky still had the old "verify_area()" name as an alias. # # - the iter_iov code had magical hardcoded knowledge of the actual # values of VERIFY_{READ,WRITE} (not that they mattered, since nothing # really used it) # # - microblaze used the type argument for a debug printout # # but other than those oddities this should be a total no-op patch. # # I tried to fix up all architectures, did fairly extensive grepping for # access_ok() uses, and the changes are trivial, but I may have missed # something. Any missed conversion should be trivially fixable, though. # # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 96d4f267e40f9509e8a66e2b39e8b95655617693 # < 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 # 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/kernel/skas/uaccess.c: In function 'do_op_one_page': /kisskb/src/arch/um/kernel/skas/uaccess.c:62:10: warning: unused variable 'buf' [-Wunused-variable] jmp_buf buf; ^ /kisskb/src/arch/um/os-Linux/umid.c: In function 'is_umdir_used': /kisskb/src/arch/um/os-Linux/umid.c:138:2: warning: ISO C90 forbids variable length array 'file' [-Wvla] char file[strlen(uml_dir) + UMID_LEN + sizeof("/pid\0")]; ^ /kisskb/src/arch/um/os-Linux/umid.c: In function 'create_pid_file': /kisskb/src/arch/um/os-Linux/umid.c:213:2: warning: ISO C90 forbids variable length array 'file' [-Wvla] char file[strlen(uml_dir) + UMID_LEN + sizeof("/pid\0")]; ^ /kisskb/src/arch/um/os-Linux/umid.c: In function 'remove_umid_dir': /kisskb/src/arch/um/os-Linux/umid.c:388:2: warning: ISO C90 forbids variable length array 'dir' [-Wvla] char dir[strlen(uml_dir) + UMID_LEN + 1], err; ^ /kisskb/src/kernel/bpf/verifier.c: In function 'check_btf_info': /kisskb/src/kernel/bpf/verifier.c:5030:4: warning: 'prev_offset' may be used uninitialized in this function [-Wmaybe-uninitialized] verbose(env, ^ /kisskb/src/kernel/bpf/verifier.c:4965:38: note: 'prev_offset' was declared here u32 i, nfuncs, urec_size, min_size, prev_offset; ^ /kisskb/src/kernel/cgroup/cgroup-v1.c: In function 'cgroup1_mount': /kisskb/src/kernel/cgroup/cgroup-v1.c:1263:3: warning: 'root' may be used uninitialized in this function [-Wmaybe-uninitialized] percpu_ref_reinit(&root->cgrp.self.refcnt); ^ /kisskb/src/security/apparmor/policy_unpack.c: In function 'unpack_trans_table': /kisskb/src/security/apparmor/policy_unpack.c:496:9: warning: 'pos' may be used uninitialized in this function [-Wmaybe-uninitialized] str[pos] = ':'; ^ /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=] } ^ /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized] if (ret == -EOPNOTSUPP) ^ drivers/dma-buf/udmabuf.o: In function `map_udmabuf': /kisskb/src/include/linux/dma-mapping.h:343: undefined reference to `dma_direct_map_sg' drivers/fpga/dfl-afu-dma-region.o: In function `afu_dma_map_region': /kisskb/src/include/linux/dma-mapping.h:377: undefined reference to `dma_direct_map_page' collect2: error: ld returned 1 exit status make[1]: * [/kisskb/src/Makefile:1026: vmlinux] Error 1 make: * [Makefile:152: sub-make] Error 2 Command '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 ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_um-allyesconfig_um-x86_64 # Build took: 0:07:16.944770
