As a result, the normal C type rules means that the # first argument to 'min()' ends up being 'unsigned long'. # # In contrast, 'maxsize' is of type 'size_t'. # # Now, 'size_t' and 'unsigned long' are always the same physical type in # the kernel, so you'd think this doesn't matter, and from an actual # arithmetic standpoint it doesn't. # # But on 32-bit architectures 'size_t' is commonly 'unsigned int', even if # it could also be 'unsigned long'. In that situation, both are unsigned # 32-bit types, but they are not the same type. # # And as a result 'min()' will complain about the distinct types (ignore # the "pointer types" part of the error message: that's an artifact of the # way we have made 'min()' check types for being the same): # # lib/iov_iter.c: In function 'iter_xarray_get_pages': # include/linux/minmax.h:20:35: error: comparison of distinct pointer types lacks a cast [-Werror] # 20 \| (!!(sizeof((typeof(x) )1 == (typeof(y) )1))) # \| ^~ # lib/iov_iter.c:1464:16: note: in expansion of macro 'min' # 1464 \| return min(nr * PAGE_SIZE - offset, maxsize); # \| ^~~ # # This was not visible on 64-bit architectures (where we always define # 'size_t' to be 'unsigned long'). # # Force these cases to use 'min_t(size_t, x, y)' to make the type explicit # and avoid the issue. # # [ Nit-picky note: technically 'size_t' doesn't have to match 'unsigned # long' arithmetically. We've certainly historically seen environments # with 16-bit address spaces and 32-bit 'unsigned long'. # # Similarly, even in 64-bit modern environments, 'size_t' could be its # own type distinct from 'unsigned long', even if it were arithmetically # identical. # # So the above type commentary is only really descriptive of the kernel # environment, not some kind of universal truth for the kinds of wild # and crazy situations that are allowed by the C standard ] # # Reported-by: Sudip Mukherjee <sudipm.mukherjee@gmail.com> # Link: https://lore.kernel.org/all/YqRyL2sIqQNDfky2@debian/ # Cc: Jeff Layton <jlayton@kernel.org> # Cc: David Howells <dhowells@redhat.com> # Cc: Al Viro <viro@zeniv.linux.org.uk> # 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 1c27f1fc1549f0e470429f5497a76ad28a37f21a # < make -s -j 32 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 # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig CONFIG_BPF_PRELOAD=n # < make -s -j 32 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 help # make -s -j 32 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 olddefconfig .config:12576:warning: override: reassigning to symbol GCC_PLUGIN_SANCOV .config:12581:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:12583:warning: override: reassigning to symbol UML_NET_SLIP .config:12586:warning: override: reassigning to symbol UML_NET_MCAST .config:12588:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 32 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/drivers/nvdimm/pmem.c:48:20: error: conflicting types for 'to_phys' static phys_addr_t to_phys(struct pmem_device pmem, phys_addr_t offset) ^ In file included from /kisskb/src/arch/um/include/asm/page.h:98:0, from /kisskb/src/arch/um/include/asm/thread_info.h:15, from /kisskb/src/include/linux/thread_info.h:60, from /kisskb/src/include/asm-generic/preempt.h:5, from ./arch/um/include/generated/asm/preempt.h:1, from /kisskb/src/include/linux/preempt.h:78, from /kisskb/src/include/linux/spinlock.h:55, from /kisskb/src/include/linux/wait.h:9, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/include/linux/highmem.h:5, from /kisskb/src/include/linux/bvec.h:10, from /kisskb/src/include/linux/blk_types.h:10, from /kisskb/src/include/linux/blkdev.h:9, from /kisskb/src/drivers/nvdimm/pmem.c:10: /kisskb/src/arch/um/include/shared/mem.h:12:29: note: previous definition of 'to_phys' was here static inline unsigned long to_phys(void virt) ^ In file included from /kisskb/src/arch/um/include/asm/page.h:114:0, from /kisskb/src/arch/um/include/asm/thread_info.h:15, from /kisskb/src/include/linux/thread_info.h:60, from /kisskb/src/include/asm-generic/preempt.h:5, from ./arch/um/include/generated/asm/preempt.h:1, from /kisskb/src/include/linux/preempt.h:78, from /kisskb/src/include/linux/spinlock.h:55, from /kisskb/src/include/linux/wait.h:9, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/include/linux/highmem.h:5, from /kisskb/src/include/linux/bvec.h:10, from /kisskb/src/include/linux/blk_types.h:10, from /kisskb/src/include/linux/blkdev.h:9, from /kisskb/src/drivers/nvdimm/pmem.c:10: /kisskb/src/drivers/nvdimm/pmem.c: In function 'pmem_dax_zero_page_range': /kisskb/src/arch/um/include/asm/page.h:105:20: error: too few arguments to function 'to_phys' #define __pa(virt) to_phys((void ) (unsigned long) (virt)) ^ /kisskb/src/include/asm-generic/memory_model.h:18:41: note: in definition of macro '__pfn_to_page' #define __pfn_to_page(pfn) (mem_map + ((pfn) -
