  • Attached is a new patch that solves the issue of getting valid credentials
    into the LOGIN message. The current code was assuming that the audit context
    had already been copied. This is not always the case for LOGIN messages.

    To solve the problem, the patch passes the task struct to the function that
    emits the message where it can get valid credentials.

  • Most audit control messages are sent over netlink.In order to properly
    log the identity of the sender of audit control messages, we would like
    to add the loginuid to the netlink_creds structure, as per the attached
    patch.

  • Attached is a patch that corrects a signed/unsigned warning. I also noticed
    that we needlessly init serial to 0. That only needs to occur if the kernel
    was compiled without the audit system.

  • We were calling ptrace_notify() after auditing the syscall and arguments,
    but the debugger could have _changed_ them before the syscall was actually
    invoked. Reorder the calls to fix that.

    While we're touching ever call to audit_syscall_entry(), we also make it
    take an extra argument: the architecture of the syscall which was made,
    because some architectures allow more than one type of syscall.

    Also add an explicit success/failure flag to audit_syscall_exit(), for
    the benefit of architectures which return that in a condition register
    rather than only returning a single register.

    Change type of syscall return value to 'long' not 'int'.

  • We log strings from userspace, such as arguments to open(). These could
    be formatted to contain \n followed by fake audit log entries. Provide
    a function for logging such strings, which gives a hex dump when the
    string contains anything but basic printable ASCII characters. Use it
    for logging filenames.

  • This fixes a deadlock on the dcache lock detected during testing at IBM
    by moving the logging of the current executable information from the
    SELinux avc_audit function to audit_log_exit (via an audit_log_task_info
    helper) for processing upon syscall exit.

    For consistency, the patch also removes the logging of other
    task-related information from avc_audit, deferring handling to
    audit_log_exit instead.

    This allows simplification of the avc_audit code, allows the exe
    information to be obtained more reliably, always includes the comm
    information (useful for scripts), and avoids including bogus task
    information for checks performed from irq or softirq.

  • Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
