Abstract: A coupler including a tubular conduit having a length disposed between a first end and a second end and a thickness disposed between an external surface and internal surface defining an interior passage, and a tubular guide, coupled to the first end, widening between the first end and a tubular guide terminal end of the tubular guide.

Abstract: A method for redirecting indirect calls to direct calls on a per-process basis includes accessing a memory code region of an operating system kernel that has a different mapping for each of one or more user processes running on the operating system kernel. The memory code region stores a first trampoline that refers directly to a second trampoline, which is an inline or outline trampoline that is correlated with a particular user process. Executing the first trampoline invokes the second trampoline, as a result of which the indirect calls are redirected to direct calls.

Abstract: A method for redirecting an indirect call in an operating system kernel to a direct call is disclosed. The direct calls are contained in trampoline code called an inline jump switch (IJS) or an outline jump switch (OJS). The IJS and OJS can operate in either a use mode, redirecting an indirect call to a direct call, a learning and update mode or fallback mode. In the learning and update mode, target addresses in a trampoline code template are learned and updated by a jump switch worker thread that periodically runs as a kernel process. When building the kernel binary, a plug-in is integrated into the kernel. The plug-in replaces call sites with a trampoline code template containing a direct call so that the template can be later updated by the jump switch worker thread.

Abstract: A method of redirecting an indirect call in a callback list associated with a list of functions that are registered, includes the steps of: upon registering the list of functions, determining a list of function pointers, each of which corresponds to an address in an associated callback; for each function pointer in the list of function pointers, adding a direct call instruction to the registration trampoline corresponding to the associated callback of the function pointer; and upon invoking the associated callback of one of the function pointers in the list of function pointers, invoking the corresponding direct call instruction in the registration trampoline.

Abstract: A method redirecting an indirect call in a call table to direct call includes the steps of: recording frequencies of calls in a frequency table; updating a search trampoline to cache, as direct calls, calls of the call table that are most frequently made according to the recorded calls in the frequency table; receiving a request to perform one of the calls in the call table; performing a search of the search trampoline to determine whether or not the requested call is cached in the search trampoline; if the requested call is cached in the search trampoline, performing the requested call that is cached in the search trampoline; and if the requested call is not cached in the search trampoline, performing the requested call by accessing the call via the call table.

Abstract: Techniques for securely supporting a global view of system memory in a physical/virtual computer system comprising a plurality of physical/virtual CPUs are provided. In one set of embodiments, the physical/virtual computer system can receive an interrupt indicating that a first physical/virtual CPU should enter a privileged CPU operating mode. The physical/virtual computer system can further determine that none of the plurality of physical/virtual CPUs are currently in the privileged CPU operating mode. In response to this determination, the physical/virtual computer system can modify the global view of system memory to include a special memory region comprising program code to be executed while in the privileged CPU operating mode; communicate, to the other physical/virtual CPUs, a signal to enter a stop state in which execution is halted but interrupts are accepted for entering the privileged CPU operating mode; and cause the first physical/virtual CPU to enter the privileged CPU operating mode.
