  • 5899f0478   netlink: pad nla_memcpy dest buffer with zeroes ... Browse Code »

    This is especially important in cases where the kernel allocs a new
    structure and expects a field to be set from a netlink attribute. If such
    attribute is shorter than expected, the rest of the field is left containing
    previous data. When such field is read back by the user space, kernel memory
    content is leaked.

  • fb41f9d71   lib/nlattr.c: remove redundant include ... Browse Code »

    nlattr.c doesn't seem to rely on anything from netdevice.h. Removing it
    yields identical objdump -d output for each of {allyes,allno,def}config,
    and eliminates more than 200 lines from the generated dependency file.

  • bfc5184b6   netlink: rate-limit leftover bytes warning and print process name ... Browse Code »

    Any process is able to send netlink messages with leftover bytes.
    Make the warning rate-limited to prevent too much log spam.

    The warning is supposed to help find userspace bugs, so print the
    triggering command name to implicate the buggy program.

    [v2: Use pr_warn_ratelimited instead of printk_ratelimited.]

  • 8b7b93243   netlink: don't compare the nul-termination in nla_strcmp ... Browse Code »

    nla_strcmp compares the string length plus one, so it's implicitly
    including the nul-termination in the comparison.

    int nla_strcmp(const struct nlattr *nla, const char *str)
    {
    int len = strlen(str) + 1;
    ...
    d = memcmp(nla_data(nla), str, len);

    However, if NLA_STRING is used, userspace can send us a string without
    the nul-termination. This is a problem since the string
    comparison will not match as the last byte may be not the
    nul-termination.

    Fix this by skipping the comparison of the nul-termination if the
    attribute data is nul-terminated. Suggested by Thomas Graf.

  • c30bc9475   netlink: validate NLA_MSECS length ... Browse Code »
    1

    L2TP for example uses NLA_MSECS like this:
    policy:
    [L2TP_ATTR_RECV_TIMEOUT] = { .type = NLA_MSECS, },
    code:
    if (info->attrs[L2TP_ATTR_RECV_TIMEOUT])
    cfg.reorder_timeout = nla_get_msecs(info->attrs[L2TP_ATTR_RECV_TIMEOUT]);

    As nla_get_msecs() is essentially nla_get_u64() plus the
    conversion to a HZ-based value, this will not properly
    reject attributes from userspace that aren't long enough
    and might overrun the message.

    Add NLA_MSECS to the attribute minlen array to check the
    size properly.

  • 908002161   nlattr: Fix build error with NET off ... Browse Code »

    We moved the netlink attribute support from net to lib in order
    for it to be available for general consumption. However, parts
    of the code (the bits that we don't need :) really depends on
    NET because the target object is sk_buff.

    This patch fixes this by wrapping them in CONFIG_NET.

    Some EXPORTs have been moved to make this work.
