Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 build-amd64-prev              5 xen-build                 fail REGR. vs. 66458
 build-i386-prev               5 xen-build                 fail REGR. vs. 66458
 test-amd64-amd64-xl-qemuu-ovmf-amd64 9 debian-hvm-install fail REGR. vs. 66458

    The proper behavior is to return upon allocation failure.
    About what to return, 0 seems the best option, looking
    at both the function and the call sites.

    libxl: Fix building libxlu_cfg_y.y with bison 3.0
    
    - Use %lex-param instead of obsolete YYLEX_PARAM to override lex scanner
      parameter
    - Change deprecated %name-prefix= to %name-prefix
    
    Tested against bison 2.4.1 and 3.0.2.
    
    This is expected to sometimes (depending on timestamps and whether the
    bison input files are edited) break building on systems with ancient
    versions of bison.  Bison 2.4.1 is known to work and was released in
    December 2008.
    
    Also, consquentially, regenerate bison output files with bison
    1:2.5.dfsg-2.1 from Debian wheezy.

    libxl: Rerun bison and flex
    
    We are going to want to cherry pick a change to the bison input, which
    will involve rerunning bison.
    
    So firstly, update the bison and flex output to that from current
    Debian wheezy (i386; 1:2.5.dfsg-2.1 and 2.5.35-10.1 respectively).
    
    There should be no functional change since there is no change to the
    source file, but we will inherit bugfixes and behavioural changes from
    the new version of bison.  So this is more a matter of hope than
    knowledge.

    x86/HVM: avoid reading ioreq state more than once
    
    Otherwise, especially when the compiler chooses to translate the
    switch() to a jump table, unpredictable behavior (and in the jump table
    case arbitrary code execution) can result.
    
    This is XSA-166.

    x86: don't leak ST(n)/XMMn values to domains first using them
    
    FNINIT doesn't alter these registers, and hence using it is
    insufficient to initialize a guest's initial state.
    
    This is CVE-2015-8555 / XSA-165.

    MSI-X: avoid array overrun upon MSI-X table writes
    
    pt_msix_init() allocates msix->msix_entry[] to just cover
    msix->total_entries entries. While pci_msix_readl() resorts to reading
    physical memory for out of bounds reads, pci_msix_writel() so far
    simply accessed/corrupted unrelated memory.
    
    pt_iomem_map()'s call to cpu_register_physical_memory() registers a
    page granular region, which is necessary as the Pending Bit Array may
    share space with the MSI-X table (but nothing else is allowed to). This
    also explains why pci_msix_readl() actually honors out of bounds reads,
    but pci_msi_writel() doesn't need to.
    
    This is XSA-164.

    blkif: Avoid double access to src->nr_segments
    
    src is stored in shared memory and src->nr_segments is dereferenced
    twice at the end of the function.  If a compiler decides to compile this
    into two separate memory accesses then the size limitation could be
    bypassed.
    
    Fix it by removing the double access to src->nr_segments.
    
    This is part of XSA-155.

    xenfb: avoid reading twice the same fields from the shared page
    
    Reading twice the same field could give the guest an attack of
    opportunity. In the case of event->type, gcc could compile the switch
    statement into a jump table, effectively ending up reading the type
    field multiple times.
    
    This is part of XSA-155.
