In particular when the compat vDSO on such architecture is built with gcc it generates the warning below: In file included from ./arch/arm64/include/asm/thread_info.h:17:0, from ./include/linux/thread_info.h:38, from ./arch/arm64/include/asm/preempt.h:5, from ./include/linux/preempt.h:78, from ./include/linux/spinlock.h:51, from ./include/linux/seqlock.h:36, from ./include/linux/time.h:6, from ./lib/vdso/gettimeofday.c:7, from <command-line>:0: ./arch/arm64/include/asm/memory.h: In function ‘__tag_set’: ./arch/arm64/include/asm/memory.h:233:15: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] u64 __addr = (u64)addr & ~__tag_shifted(0xff); ^ In file included from ./arch/arm64/include/asm/pgtable-hwdef.h:8:0, from ./arch/arm64/include/asm/processor.h:34, from ./arch/arm64/include/asm/elf.h:118, from ./include/linux/elf.h:5, from ./include/linux/elfnote.h:62, from arch/arm64/kernel/vdso32/note.c:11: ./arch/arm64/include/asm/memory.h: In function ‘__tag_set’: ./arch/arm64/include/asm/memory.h:233:15: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] u64 __addr = (u64)addr & ~__tag_shifted(0xff); The same porting does not build at all when the selected compiler is clang. I started an investigation to try to understand better the problem and after various discussions at Plumbers and Recipes last year the conclusion was that the vDSO library as it stands it is including more headers that it needs. In particular, being a user-space library, it should require only the UAPI and a minimal vDSO kernel interface instead of all the kernel-related inline functions which are not directly used and in some cases can have side effects. To solve the problem, I decided to use the approach below: * Extract from include/linux/ the vDSO required kernel interface and place it in include/vdso/ * Make sure that where meaningful the kernel includes "vdso" headers. * Limit the vDSO library to include headers coming only from UAPI and "vdso" (with 2 exceptions compiler.h for barriers and param.h for HZ). * Adapt all the architectures that support the unified vDSO library to use "vdso" headers. According to me this approach allows up to exercise a better control on what the vDSO library can include and to prevent potential issues in future. This patch series contains the implementation of the described approach. The "vdso" headers have been verified on all the architectures that support unified vDSO using the vdsotest [3] testsuite for what concerns the vDSO part and randconfig to verify that they are included in the correct places. To simplify the testing, a copy of the patchset on top of a recent linux tree can be found at [4].
