If the mount had a parent then verify that the # caller and the mount namespace the mount is attached to match and if # not make sure that it's an anonymous mount. # # But the real rootfs falls into neither category. It is neither an # anoymous mount because it is obviously attached to the initial mount # namespace but it also obviously doesn't have a parent mount. So that # means legacy mount(2) allows changing mount properties on the real # rootfs but mount_setattr(2) blocks this. This causes regressions (See # the commit for details). # # Fix this by relaxing the check. If the mount has a parent or if it # isn't a detached mount, verify that the mount namespaces of the # caller and the mount are the same. Technically, we could probably # write this even simpler and check that the mount namespaces match if # it isn't a detached mount. But the slightly longer check makes it # clearer what conditions one needs to think about. # # * tag 'vfs-6.8-rc5.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: # fs: relax mount_setattr() permission checks # remap_range: merge do_clone_file_range() into vfs_clone_file_range() # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 716f4aaa7b48a55c73d632d0657b35342b1fefd7 # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig # < make -s -j 40 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- olddefconfig .config:14882:warning: override: reassigning to symbol MIPS_CPS_NS16550_SHIFT # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- In file included from /kisskb/src/include/linux/string.h:292, from /kisskb/src/include/linux/bitmap.h:12, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/include/linux/smp.h:13, from /kisskb/src/arch/mips/include/asm/cpu-type.h:12, from /kisskb/src/arch/mips/include/asm/timex.h:19, from /kisskb/src/include/linux/timex.h:67, from /kisskb/src/include/linux/time32.h:13, from /kisskb/src/include/linux/time.h:60, from /kisskb/src/include/linux/jiffies.h:10, from /kisskb/src/include/linux/ktime.h:25, from /kisskb/src/include/linux/iopoll.h:11, from /kisskb/src/drivers/crypto/intel/qat/qat_common/adf_gen4_hw_data.c:3: In function 'fortify_memcpy_chk', inlined from 'adf_gen4_init_thd2arb_map' at /kisskb/src/drivers/crypto/intel/qat/qat_common/adf_gen4_hw_data.c:401:3: /kisskb/src/include/linux/fortify-string.h:528:4: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()?
