    tunables: Terminate if end of input is reached (CVE-2023-4911)
    
    The string parsing routine may end up writing beyond bounds of tunestr
    if the input tunable string is malformed, of the form name=name=val.
    This gets processed twice, first as name=name=val and next as name=val,
    resulting in tunestr being name=name=val:name=val, thus overflowing
    tunestr.
    
    Terminate the parsing loop at the first instance itself so that tunestr
    does not overflow.
    
    This also fixes up tst-env-setuid-tunables to actually handle failures
    correct and add new tests to validate the fix for this CVE.

    getaddrinfo: Fix use after free in getcanonname (CVE-2023-4806)
    
    When an NSS plugin only implements the _gethostbyname2_r and
    _getcanonname_r callbacks, getaddrinfo could use memory that was freed
    during tmpbuf resizing, through h_name in a previous query response.
    
    The backing store for res->at->name when doing a query with
    gethostbyname3_r or gethostbyname2_r is tmpbuf, which is reallocated in
    gethosts during the query.  For AF_INET6 lookup with AI_ALL |
    AI_V4MAPPED, gethosts gets called twice, once for a v6 lookup and second
    for a v4 lookup.  In this case, if the first call reallocates tmpbuf
    enough number of times, resulting in a malloc, th->h_name (that
    res->at->name refers to) ends up on a heap allocated storage in tmpbuf.
    Now if the second call to gethosts also causes the plugin callback to
    return NSS_STATUS_TRYAGAIN, tmpbuf will get freed, resulting in a UAF
    reference in res->at->name.  This then gets dereferenced in the
    getcanonname_r plugin call, resulting in the use after free.
    
    Fix this by copying h_name over and freeing it at the end.  This
    resolves BZ #30843, which is assigned CVE-2023-4806.

    Without passing alt_dns_packet_buffer, __res_context_search can only

    elf: Always call destructors in reverse constructor order (bug 30785)
    
    The current implementation of dlclose (and process exit) re-sorts the
    link maps before calling ELF destructors.  Destructor order is not the
    reverse of the constructor order as a result: The second sort takes
    relocation dependencies into account, and other differences can result
    from ambiguous inputs, such as cycles.  (The force_first handling in
    _dl_sort_maps is not effective for dlclose.)  After the changes in
    this commit, there is still a required difference due to
    dlopen/dlclose ordering by the application, but the previous
    discrepancies went beyond that.
    
    A new global (namespace-spanning) list of link maps,
    _dl_init_called_list, is updated right before ELF constructors are
    called from _dl_init.
    
    In dl_close_worker, the maps variable, an on-stack variable length
    array, is eliminated.  (VLAs are problematic, and dlclose should not
    call malloc because it cannot readily deal with malloc failure.)
    Marking still-used objects uses the namespace list directly, with
    next and next_idx replacing the done_index variable.
    
    After marking, _dl_init_called_list is used to call the destructors
    of now-unused maps in reverse destructor order.  These destructors
    can call dlopen.  Previously, new objects do not have l_map_used set.
    This had to change: There is no copy of the link map list anymore,
    so processing would cover newly opened (and unmarked) mappings,
    unloading them.  Now, _dl_init (indirectly) sets l_map_used, too.
    (dlclose is handled by the existing reentrancy guard.)
    
    After _dl_init_called_list traversal, two more loops follow.  The
    processing order changes to the original link map order in the
    namespace.  Previously, dependency order was used.  The difference
    should not matter because relocation dependencies could already
    reorder link maps in the old code.
    
    The changes to _dl_fini remove the sorting step and replace it with
    a traversal of _dl_init_called_list.  The l_direct_opencount
    decrement outside the loader lock is removed because it appears
    incorrect: the counter manipulation could race with other dynamic
    loader operations.
    
    tst-audit23 needs adjustments to the changes in LA_ACT_DELETE
    notifications.  The new approach for checking la_activity should
    make it clearer that la_activty calls come in pairs around namespace
    updates.
    
    The dependency sorting test cases need updates because the destructor
    order is always the opposite order of constructor order, even with
    relocation dependencies or cycles present.
    
    There is a future cleanup opportunity to remove the now-constant
    force_first and for_fini arguments from the _dl_sort_maps function.
    
    Fixes commit 1df71d32fe5f5905ffd5d100e5e9ca8ad62 ("elf: Implement
    force_first handling in _dl_sort_maps_dfs (bug 28937)").

    io: Fix record locking contants for powerpc64 with __USE_FILE_OFFSET64
    
    Commit 5f828ff824e3b7cd1 ("io: Fix F_GETLK, F_SETLK, and F_SETLKW for
    powerpc64") fixed an issue with the value of the lock constants on
    powerpc64 when not using __USE_FILE_OFFSET64, but it ended-up also
    changing the value when using __USE_FILE_OFFSET64 causing an API change.
    
    Fix that by also checking that define, restoring the pre
    4d0fe291aed3a476a commit values:
    
    Default values:
    - F_GETLK: 5
    - F_SETLK: 6
    - F_SETLKW: 7
    
    With -D_FILE_OFFSET_BITS=64:
    - F_GETLK: 12
    - F_SETLK: 13
    - F_SETLKW: 14
    
    At the same time, it has been noticed that there was no test for io lock
    with __USE_FILE_OFFSET64, so just add one.
    
    Tested on x86_64-linux-gnu, i686-linux-gnu and
    powerpc64le-unknown-linux-gnu.
    
    Resolves: BZ #30804.

    malloc: Remove bin scanning from memalign (bug 30723)
    
    On the test workload (mpv --cache=yes with VP9 video decoding), the
    bin scanning has a very poor success rate (less than 2%).  The tcache
    scanning has about 50% success rate, so keep that.
    
    Update comments in malloc/tst-memalign-2 to indicate the purpose
    of the tests.  Even with the scanning removed, the additional
    merging opportunities since commit 542b1105852568c3ebc712225ae78b
    ("malloc: Enable merging of remainders in memalign (bug 30723)")
    are sufficient to pass the existing large bins test.
    
    Remove leftover variables from _int_free from refactoring in the
    same commit.

    malloc: Enable merging of remainders in memalign (bug 30723)
    
    Previously, calling _int_free from _int_memalign could put remainders
    into the tcache or into fastbins, where they are invisible to the
    low-level allocator.  This results in missed merge opportunities
    because once these freed chunks become available to the low-level
    allocator, further memalign allocations (even of the same size are)
    likely obstructing merges.
    
    Furthermore, during forwards merging in _int_memalign, do not
    completely give up when the remainder is too small to serve as a
    chunk on its own.  We can still give it back if it can be merged
    with the following unused chunk.  This makes it more likely that
    memalign calls in a loop achieve a compact memory layout,
    independently of initial heap layout.
    
    Drop some useless (unsigned long) casts along the way, and tweak
    the style to more closely match GNU on changed lines.

    Since i686 provides the fortified wrappers for memcpy, mempcpy,

    nscd: Do not rebuild getaddrinfo (bug 30709)
    
    The nscd daemon caches hosts data from NSS modules verbatim, without
    filtering protocol families or sorting them (otherwise separate caches
    would be needed for certain ai_flags combinations).  The cache
    implementation is complete separate from the getaddrinfo code.  This
    means that rebuilding getaddrinfo is not needed.  The only function
    actually used is __bump_nl_timestamp from check_pf.c, and this change
    moves it into nscd/connections.c.
    
    Tested on x86_64-linux-gnu with -fexceptions, built with
    build-many-glibcs.py.  I also backported this patch into a distribution
    that still supports nscd and verified manually that caching still works.

    linux: Set internal DIR filepos as off64_t (BZ #23960, BZ #24050)
    
    It allows to obtain the expected entry offset on telldir and set
    it correctly on seekdir on platforms where long int is smaller
    than off64_t.
    
    On such cases opendir creates a map entry between the DIR d_off
    offset and the returned long int (the telldir return value).
    seekdir will then set the correct offset from the internal list
    using the telldir as the list key.
    
    It also removes the overflow check on readdir and the returned value
    will be truncated by the non-LFS off_t size.  As Joseph has noted
    in BZ #23960 comment #22, d_off is an opaque value and since
    telldir/seekdir works regardless of the returned dirent d_off value.
    
    Finally it removes the requirement to check for overflow values on
    telldir (BZ #24050).
    
    Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc-linux-gnu,
    and arm-linux-gnueabihf.

    Force -O0 in conform tests to survive $CC changes
    
    In bug #659030 Gentoo started passing user's CFLAGS via $CC variable.
    conform tests should but are not ready to handle -O1/-O2 yet.
    Tests fail to validate headers due to inlining of weak symbol aliases
    and other problems. Let's force it back to -O0 until it's fixed upstream.
    
    Original patch by Sergei, ported to the new python test framework by Andreas

    Disable ldconfig during install
    
    Do not bother running ldconfig on DESTDIR.  It's a waste of time as we
    won't use the result (portage will rebuild the cache after install).
    Also, the Gentoo sandbox does not currently catch chroot() behavior so
    we end up (incorrectly) flagging it as a violation as a write to /etc.
