This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here.

There are already a number of filter flags in\n/proc/\u003cpid\u003e/coredump_filter, however, these allow one to specify \u0027types\u0027\nof kernel memory, not specific address ranges (which is needed in this\ncase).\n\nSince there are no more vma flags available, the first patch eliminates\nthe need for the \u0027VM_ALWAYSDUMP\u0027 flag. The flag is used internally by\nthe kernel to mark vdso and vsyscall pages. However, it is simple\nenough to check if a vma covers a vdso or vsyscall page without the need\nfor this flag.\n\nThe second patch then replaces the \u0027VM_ALWAYSDUMP\u0027 flag with a new\n\u0027VM_NODUMP\u0027 flag, which can be set by userspace using new madvise flags:\n\u0027MADV_DONTDUMP\u0027, and unset via \u0027MADV_DODUMP\u0027. The core dump filters\ncontinue to work the same as before unless \u0027MADV_DONTDUMP\u0027 is set on the\nregion.\n\nThe qemu code which implements this features is at:\n\n http://people.redhat.com/~jbaron/qemu-dump/qemu-dump.patch\n\nIn my testing the qemu core dump shrunk from 383MB -\u003e 13MB with this\npatch.\n\nI also believe that the \u0027MADV_DONTDUMP\u0027 flag might be useful for\nsecurity sensitive apps, which might want to select which areas are\ndumped.\n\nThis patch:\n\nThe VM_ALWAYSDUMP flag is currently used by the coredump code to\nindicate that a vma is part of a vsyscall or vdso section. However, we\ncan determine if a vma is in one these sections by checking it against\nthe gate_vma and checking for a non-NULL return value from\narch_vma_name().

This helper was wrong and could indicate that a valid\npointer returned to userspace was a failed syscall. The fix is to fix the\nlayering foolishness. We now pass audit_syscall_exit a struct pt_reg and it\nin turns calls back into arch code to collect the return value and to\ndetermine if the syscall was a success or failure. We also define a generic\nis_syscall_success() macro which determines success/failure based on if the\nvalue is \u003c -MAX_ERRNO. This works for arches like x86 which do not use a\nseparate mechanism to indicate syscall failure.\n\nWe make both the is_syscall_success() and regs_return_value() static inlines\ninstead of macros. The reason is because the audit function must take a void*\nfor the regs. (uml calls theirs struct uml_pt_regs instead of just struct\npt_regs so audit_syscall_exit can\u0027t take a struct pt_regs). Since the audit\nfunction takes a void* we need to use static inlines to cast it back to the\narch correct structure to dereference it.\n\nThe other major change is that on some arches, like ia64, MIPS and ppc, we\nchange regs_return_value() to give us the negative value on syscall failure.\nTHE only other user of this macro, kretprobe_example.c, won\u0027t notice and it\nmakes the value signed consistently for the audit functions across all archs.\n\nIn arch/sh/kernel/ptrace_64.c I see that we were using regs[9] in the old\naudit code as the return value. But the ptrace_64.h code defined the macro\nregs_return_value() as regs[3]. I have no idea which one is correct, but this\npatch now uses the regs_return_value() function, so it now uses regs[3].\n\nFor powerpc we previously used regs-\u003eresult but now use the\nregs_return_value() function which uses regs-\u003egprs[3]. regs-\u003egprs[3] is\nalways positive so the regs_return_value(), much like ia64 makes it negative\nbefore calling the audit code when appropriate.\n\nSigned-off-by: Eric Paris \u003ceparis@redhat.com\u003e\nAcked-by: H.
