https://bugzilla.kernel.org/show_bug.cgi?id=205957 --- Comment #16 from aladjev.andrew@xxxxxxxxx (aladjev.andrew@xxxxxxxxx) --- We don't need to create a patch for kernel about this compat syscall, because it already supports "__X32_SYSCALL_BIT". We need just to enable it using "CONFIG_X86_X32=y" kernel config. Recompiled kernel will expose all x86 related syscalls in x32 mode. I've tested that "__X32_SYSCALL_BIT + 217" works completely the same as my "SYS_getdents64_x32". Function "in_x32_syscall" works perfect. We can patch glibc to redirect getdents64 syscall to x32 compatible one. My previous assumption was wrong. Patching qemu will be very bad solution, because it means that large file support will be broken in all applications, not only glibc. For now only glibc wants to convert dirent64 to dirent just by copying fields. Regular application don't want to emulate getdents using getdents64 and it will not touch dirent64. So we shouldn't interfere in qemu syscalls. -- You are receiving this mail because: You are watching the assignee of the bug.
