  • 50935339c   netfilter: Replace HTTP links with HTTPS ones ... Browse Code »

    Rationale:
    Reduces attack surface on kernel devs opening the links for MITM
    as HTTPS traffic is much harder to manipulate.

    Deterministic algorithm:
    For each file:
    If not .svg:
    For each line:
    If doesn't contain `\bxmlns\b`:
    For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
    If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
    If both the HTTP and HTTPS versions
    return 200 OK and serve the same content:
    Replace HTTP with HTTPS.

  • a7f7f6248   treewide: replace '---help---' in Kconfig files with 'help' ... Browse Code »

    Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
    '---help---'"), the number of '---help---' has been gradually
    decreasing, but there are still more than 2400 instances.

    This commit finishes the conversion. While I touched the lines,
    I also fixed the indentation.

    There are a variety of indentation styles found.

    a) 4 spaces + '---help---'
    b) 7 spaces + '---help---'
    c) 8 spaces + '---help---'
    d) 1 space + 1 tab + '---help---'
    e) 1 tab + '---help---' (correct indentation)
    f) 1 tab + 1 space + '---help---'
    g) 1 tab + 2 spaces + '---help---'

    In order to convert all of them to 1 tab + 'help', I ran the
    following commend:

    $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

    Instead of having all the sysctl handlers deal with user pointers, which
    is rather hairy in terms of the BPF interaction, copy the input to and
    from userspace in common code. This also means that the strings are
    always NUL-terminated by the common code, making the API a little bit
    safer.

    As most handler just pass through the data to one of the common handlers
    a lot of the changes are mechnical.

  • bd085ef67   net: add bool confirm_neigh parameter for dst_ops.update_pmtu ... Browse Code »

    The MTU update code is supposed to be invoked in response to real
    networking events that update the PMTU. In IPv6 PMTU update function
    __ip6_rt_update_pmtu() we called dst_confirm_neigh() to update neighbor
    confirmed time.

    But for tunnel code, it will call pmtu before xmit, like:
    - tnl_update_pmtu()
    - skb_dst_update_pmtu()
    - ip6_rt_update_pmtu()
    - __ip6_rt_update_pmtu()
    - dst_confirm_neigh()

    If the tunnel remote dst mac address changed and we still do the neigh
    confirm, we will not be able to update neigh cache and ping6 remote
    will failed.

    So for this ip_tunnel_xmit() case, _EVEN_ if the MTU is changed, we
    should not be invoking dst_confirm_neigh() as we have no evidence
    of successful two-way communication at this point.

    On the other hand it is also important to keep the neigh reachability fresh
    for TCP flows, so we cannot remove this dst_confirm_neigh() call.

    To fix the issue, we have to add a new bool parameter for dst_ops.update_pmtu
    to choose whether we should do neigh update or not. I will add the parameter
    in this patch and set all the callers to true to comply with the previous
    way, and fix the tunnel code one by one on later patches.

    v5: No change.
    v4: No change.
    v3: Do not remove dst_confirm_neigh, but add a new bool parameter in
    dst_ops.update_pmtu to control whether we should do neighbor confirm.
    Also split the big patch to small ones for each area.
    v2: Remove dst_confirm_neigh in __ip6_rt_update_pmtu.

  • 8cb081746   netlink: make validation more configurable for future strictness ... Browse Code »

    We currently have two levels of strict validation:

    1) liberal (default)
    - undefined (type >= max) & NLA_UNSPEC attributes accepted
    - attribute length >= expected accepted
    - garbage at end of message accepted
    2) strict (opt-in)
    - NLA_UNSPEC attributes accepted
    - attribute length >= expected accepted

    Split out parsing strictness into four different options:
    * TRAILING - check that there's no trailing data after parsing
    attributes (in message or nested)
    * MAXTYPE - reject attrs > max known type
    * UNSPEC - reject attributes with NLA_UNSPEC policy entries
    * STRICT_ATTRS - strictly validate attribute size

    The default for future things should be *everything*.
    The current *_strict() is a combination of TRAILING and MAXTYPE,
    and is renamed to _deprecated_strict().
    The current regular parsing has none of this, and is renamed to
    *_parse_deprecated().

    Additionally it allows us to selectively set one of the new flags
    even on old policies. Notably, the UNSPEC flag could be useful in
    this case, since it can be arranged (by filling in the policy) to
    not be an incompatible userspace ABI change, but would then going
    forward prevent forgetting attribute entries. Similar can apply
    to the POLICY flag.

    We end up with the following renames:
    * nla_parse -> nla_parse_deprecated
    * nla_parse_strict -> nla_parse_deprecated_strict
    * nlmsg_parse -> nlmsg_parse_deprecated
    * nlmsg_parse_strict -> nlmsg_parse_deprecated_strict
    * nla_parse_nested -> nla_parse_nested_deprecated
    * nla_validate_nested -> nla_validate_nested_deprecated

    Using spatch, of course:

    For this patch, don't actually add the strict, non-renamed versions
    yet so that it breaks compile if I get it wrong.

    Also, while at it, make nla_validate and nla_parse go down to a
    common __nla_validate_parse() function to avoid code duplication.

    Ultimately, this allows us to have very strict validation for every
    new caller of nla_parse()/nlmsg_parse() etc as re-introduced in the
    next patch, while existing things will continue to work as is.

    In effect then, this adds fully strict validation for any new command.

  • ae0be8de9   netlink: make nla_nest_start() add NLA_F_NESTED flag ... Browse Code »

    Even if the NLA_F_NESTED flag was introduced more than 11 years ago, most
    netlink based interfaces (including recently added ones) are still not
    setting it in kernel generated messages. Without the flag, message parsers
    not aware of attribute semantics (e.g. wireshark dissector or libmnl's
    mnl_nlmsg_fprintf()) cannot recognize nested attributes and won't display
    the structure of their contents.

    Unfortunately we cannot just add the flag everywhere as there may be
    userspace applications which check nlattr::nla_type directly rather than
    through a helper masking out the flags. Therefore the patch renames
    nla_nest_start() to nla_nest_start_noflag() and introduces nla_nest_start()
    as a wrapper adding NLA_F_NESTED. The calls which add NLA_F_NESTED manually
    are rewritten to use nla_nest_start().

    Except for changes in include/net/netlink.h, the patch was generated using
    this semantic patch:

    @@ expression E1, E2; @@
    -nla_nest_start(E1, E2)

  • 50c293663   decnet: fix DN_IFREQ_SIZE ... Browse Code »

    Digging through the ioctls with Al because of the previous
    patches, we found that on 64-bit decnet's dn_dev_ioctl()
    is wrong, because struct ifreq::ifr_ifru is actually 24
    bytes (not 16 as expected from struct sockaddr) due to the
    ifru_map and ifru_settings members.

    Clearly, decnet expects the ioctl to be called with a struct
    like
    struct ifreq_dn {
    char ifr_name[IFNAMSIZ];
    struct sockaddr_dn ifr_addr;
    };

    since it does
    struct ifreq *ifr = ...;
    struct sockaddr_dn *sdn = (struct sockaddr_dn *)&ifr->ifr_addr;

    This means that DN_IFREQ_SIZE is too big for what it wants on
    64-bit, as it is
    sizeof(struct ifreq) - sizeof(struct sockaddr) +
    sizeof(struct sockaddr_dn)

    This assumes that sizeof(struct sockaddr) is the size of ifr_ifru
    but that isn't true.

    Fix this to use offsetof(struct ifreq, ifr_ifru).

    This indeed doesn't really matter much - the result is that we
    copy in/out 8 bytes more than we should on 64-bit platforms. In
    case the "struct ifreq_dn" lands just on the end of a page though
    it might lead to faults.

    As far as I can tell, it has been like this forever, so it seems
    very likely that nobody cares.

  • bb3e16ad8   net, decnet: use struct_size() in kzalloc() ... Browse Code »

    One of the more common cases of allocation size calculations is finding the
    size of a structure that has a zero-sized array at the end, along with memory
    for some number of elements for that array. For example:

    struct foo {
    int stuff;
    struct boo entry[];
    };

    instance = kzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);

    Instead of leaving these open-coded and prone to type mistakes, we can now
    use the new struct_size() helper:

    instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

    This code was detected with the help of Coccinelle.

  • a11e1d432   Revert changes to convert to ->poll_mask() and aio IOCB_CMD_POLL ... Browse Code »

    The poll() changes were not well thought out, and completely
    unexplained. They also caused a huge performance regression, because
    "->poll()" was no longer a trivial file operation that just called down
    to the underlying file operations, but instead did at least two indirect
    calls.

    Indirect calls are sadly slow now with the Spectre mitigation, but the
    performance problem could at least be largely mitigated by changing the
    "->get_poll_head()" operation to just have a per-file-descriptor pointer
    to the poll head instead. That gets rid of one of the new indirections.

    But that doesn't fix the new complexity that is completely unwarranted
    for the regular case. The (undocumented) reason for the poll() changes
    was some alleged AIO poll race fixing, but we don't make the common case
    slower and more complex for some uncommon special case, so this all
    really needs way more explanations and most likely a fundamental
    redesign.

    [ This revert is a revert of about 30 different commits, not reverted
    individually because that would just be unnecessarily messy - Linus ]

    components. fib6_info for the routing table, and fib6_nh for sets of
    nexthops, which thus can be shared. From David Ahern.

    7) Add bpf_xdp_adjust_tail helper, which can be used to generate ICMP
    messages from XDP programs. From Nikita V. Shirokov.

    18) Add AF_XDP sockets, with zerocopy support infrastructure as well.
    From Björn Töpel.

    19) Remove indirect load support from all of the BPF JITs and handle
    these operations in the verifier by translating them into native BPF
    instead. From Daniel Borkmann.

    20) Add GRO support to ipv6 gre tunnels, from Eran Ben Elisha.

    21) Allow XDP programs to do lookups in the main kernel routing tables
    for forwarding. From David Ahern.
