  • 2cd23553b   x86/asm/entry: Rename compat syscall entry points ... Browse Code »

    Rename the following system call entry points:

    ia32_cstar_target -> entry_SYSCALL_compat
    ia32_syscall -> entry_INT80_compat

    The generic naming scheme for x86 system call entry points is:

    entry_MNEMONIC_qualifier

    where 'qualifier' is one of _32, _64 or _compat.

  • 48e08d0fb   x86, entry: Switch stacks on a paranoid entry from userspace ... Browse Code »

    This causes all non-NMI, non-double-fault kernel entries from
    userspace to run on the normal kernel stack. Double-fault is
    exempt to minimize confusion if we double-fault directly from
    userspace due to a bad kernel stack.

    This is, suprisingly, simpler and shorter than the current code. It
    removes the IMO rather frightening paranoid_userspace path, and it
    make sync_regs much simpler.

    There is no risk of stack overflow due to this change -- the kernel
    stack that we switch to is empty.

    This will also enable us to create non-atomic sections within
    machine checks from userspace, which will simplify memory failure
    handling. It will also allow the upcoming fsgsbase code to be
    simplified, because it doesn't need to worry about usergs when
    scheduling in paranoid_exit, as that code no longer exists.

    Commit 3ae36655b97a03fa1decf72f04078ef945647c1a (x86-64: Rework vsyscall
    emulation and add vsyscall= parameter) removed the special use of the
    0xcc IDT vector.

    Remove it from Documentation/x86/entry_64.txt also.
