    Merge alpha architecture update from Michael Cree:
    "The Alpha Maintainer, Matt Turner, is currently unavailable, so I have
    collected up patches that have been posted to the linux-alpha mailing
    list over the last couple of months, and are forwarding them to you in
    the hope that you are prepared to accept them via me.

    The patches by Al Viro and myself I have been running against kernels
    for two months now so have had quite a bit of testing. All except one
    patch were intended for the 3.5 kernel but because of Matt's
    unavailability never got forwarded to you."

    The following build error occurred during an alpha build:

    net/core/sock.c:274:36: error: initializer element is not constant

    Dave Anglin says:
    > Here is the line in sock.i:
    >
    > struct static_key memalloc_socks = ((struct static_key) { .enabled =
    > ((atomic_t) { (0) }) });

    The above line contains two compound literals. It also uses a designated
    initializer to initialize the field enabled. A compound literal is not a
    constant expression.

    The location of the above statement isn't fully clear, but if a compound
    literal occurs outside the body of a function, the initializer list must
    consist of constant expressions.

    After commit ec2212088c42 ("Disintegrate asm/system.h for Alpha"), the
    fpu.h header which we install for userland started depending on
    special_insns.h which is not installed.

    However, fpu.h only uses that for __KERNEL__ code, so protect the
    inclusion the same way to avoid build breakage in glibc:

  • f2db633d3   alpha: Use new generic strncpy_from_user() and strnlen_user() ... Browse Code »

    Similar to x86/sparc/powerpc implementations except:
    1) we implement an extremely efficient has_zero()/find_zero()
    sequence with both prep_zero_mask() and create_zero_mask()
    no-operations.
    2) Our output from prep_zero_mask() differs in that only the
    lowest eight bits are used to represent the zero bytes
    nevertheless it can be safely ORed with other similar masks
    from prep_zero_mask() and forms input to create_zero_mask(),
    the two fundamental properties prep_zero_mask() must satisfy.

    Tests on EV67 and EV68 CPUs revealed that the generic code is
    essentially as fast (to within 0.5% of CPU cycles) of the old
    Alpha specific code for large quadword-aligned strings, despite
    the 30% extra CPU instructions executed. In contrast, the
    generic code for unaligned strings is substantially slower (by
    more than a factor of 3) than the old Alpha specific code.

    Currently we export SOCK_NONBLOCK to user space but that conflicts with
    the definition from glibc leading to compilation errors in user programs
    (e.g. see Debian bug #658460).

    The generic socket.h restricts the definition of SOCK_NONBLOCK to the
    kernel, as does the MIPS specific socket.h, so let's do the same on
    Alpha.

  • 515c7af85   x32: Use compat shims for {g,s}etsockopt ... Browse Code »

    Some of the arguments to {g,s}etsockopt are passed in userland pointers.
    If we try to use the 64bit entry point, we end up sometimes failing.

    For example, dhcpcd doesn't run in x32:
    # dhcpcd eth0
    dhcpcd[1979]: version 5.5.6 starting
    dhcpcd[1979]: eth0: broadcasting for a lease
    dhcpcd[1979]: eth0: open_socket: Invalid argument
    dhcpcd[1979]: eth0: send_raw_packet: Bad file descriptor

    The code in particular is getting back EINVAL when doing:
    struct sock_fprog pf;
    setsockopt(s, SOL_SOCKET, SO_ATTACH_FILTER, &pf, sizeof(pf));

    Diving into the kernel code, we can see:
    include/linux/filter.h:
    struct sock_fprog {
    unsigned short len;
    struct sock_filter __user *filter;
    };

    net/core/sock.c:
    case SO_ATTACH_FILTER:
    ret = -EINVAL;
    if (optlen == sizeof(struct sock_fprog)) {
    struct sock_fprog fprog;

    ret = -EFAULT;
    if (copy_from_user(&fprog, optval, sizeof(fprog)))
    break;

    ret = sk_attach_filter(&fprog, sk);
    }
    break;

    arch/x86/syscalls/syscall_64.tbl:
    54 common setsockopt sys_setsockopt
    55 common getsockopt sys_getsockopt

    So for x64, sizeof(sock_fprog) is 16 bytes. For x86/x32, it's 8 bytes.
    This comes down to the pointer being 32bit for x32, which means we need
    to do structure size translation. But since x32 comes in directly to
    sys_setsockopt, it doesn't get translated like x86.

    After changing the syscall table and rebuilding glibc with the new kernel
    headers, dhcp runs fine in an x32 userland.

    Oddly, it seems like Linus noted the same thing during the initial port,
    but I guess that was missed/lost along the way:

  • f1c630018   x86, apic: fix broken legacy interrupts in the logical apic mode ... Browse Code »

    Recent commit 332afa656e76458ee9cf0f0d123016a0658539e4 cleaned up
    a workaround that updates irq_cfg domain for legacy irq's that
    are handled by the IO-APIC. This was assuming that the recent
    changes in assign_irq_vector() were sufficient to remove the workaround.

    But this broke couple of AMD platforms. One of them seems to be
    sending interrupts to the offline cpu's, resulting in spurious
    "No irq handler for vector xx (irq -1)" messages when those cpu's come online.
    And the other platform seems to always send the interrupt to the last logical
    CPU (cpu-7). Recent changes had an unintended side effect of using only logical
    cpu-0 in the IO-APIC RTE (during boot for the legacy interrupts) and this
    broke the legacy interrupts not getting routed to the cpu-7 on the AMD
    platform, resulting in a boot hang.

    For now, reintroduce the removed workaround, (essentially not allowing the
    vector to change for legacy irq's when io-apic starts to handle the irq. Which
    also addressed the uninteded sife effect of just specifying cpu-0 in the
    IO-APIC RTE for those irq's during boot).

    Commit 5a783cbc4836 ("ARM: 7478/1: errata: extend workaround for erratum
    #720789") added workarounds for erratum #720789 to the range TLB
    invalidation functions with the observation that the erratum only
    affects SMP platforms. However, when running an SMP_ON_UP kernel on a
    uniprocessor platform we must take care to preserve the ASID as the
    workaround is not required.

    This patch ensures that we don't set the ASID to 0 when flushing the TLB
    on such a system, preserving the original behaviour with the workaround
    disabled.

  • f5f2025ef   ARM: 7488/1: mm: use 5 bits for swapfile type encoding ... Browse Code »

    Page migration encodes the pfn in the offset field of a swp_entry_t.
    For LPAE, we support physical addresses of up to 36 bits (due to
    sparsemem limitations with the size of page flags), requiring 24 bits
    to represent a pfn. A further 3 bits are used to encode a swp_entry into
    a pte, leaving 5 bits for the type field. Furthermore, the core code
    defines MAX_SWAPFILES_SHIFT as 5, so the additional type bit does not
    get used.

    This patch reduces the width of the type field to 5 bits, allowing us
    to create up to 31 swapfiles of 64GB each.
