Also track the number of connections in "connecting" and "shared" state (in addition to the "exclusive" state). Apply a configurable limit to these connections. The logic to apply the limit to connections in "shared" state is pretty simple: When the limit is reached no new connections are allowed. The logic to apply the limit to connections in "connecting" state (this is the state you are in *before* successful authentication) is slightly different: A new connect kicks out the oldest client which is still in "connecting" state. This avoids a easy DoS by unauthenticated users by simply opening connections until the limit is reached.

Not all targets define a full set of suffix strings for the NB_MMU_MODES that they have. In this situation, don't define any helper functions for that mode, rather than defining helper functions with no suffix at all. The MMU mode is still functional; it is merely not directly accessible via cpu_ld*_MODE from target helper functions. Also add an "NB_MMU_MODES >= 2" check to the definition of the mode 1 helpers -- some targets only define one MMU mode.

Use inline functions rather than macros for cpu_ld/st accessors for the *-user configurations, as we already do for softmmu. This has a two advantages: * we can actually typecheck our arguments * we don't need to leak the _raw macros everywhere Since the _kernel functions were only used by target-i386/seg_helper.c, put the definitions for them in that file too. (It already has the similar template include code to define them for the softmmu case, so it makes sense to have it deal with defining them for user-only.)

The monitor code for doing a memory_dump() was using ld*_raw() to do target-CPU accesses out of a local buf[] array. The correct functions for this purpose are ld*_p(), which take a host pointer, rather than ld*_raw(), which take an integer representing a guest address and are somewhat meaningless in softmmu configurations. Nobody noticed because for softmmu the _raw functions are the same as ldl_p but with some extra casts thrown in. Switch to using the correct functions instead.

The TARGET_HAS_ICE #define is intended to indicate whether a target-* guest CPU implementation supports the breakpoint handling. However, all our guest CPUs have that support (the only two which do not define TARGET_HAS_ICE are unicore32 and openrisc, and in both those cases the bp support is present and the lack of the #define is just a bug). So remove the #define entirely: all new guest CPU support should include breakpoint handling as part of the basic implementation.

Make sure that all generated C structs have at least one field; this avoids potential issues with attempting to malloc space for zero-length structs in C (g_malloc(sizeof struct) would return NULL). It also avoids an incompatibility with C++ (where an empty struct is size 1); that isn't important to us now but might be in future. Generated empty structures look like this: struct Abort { char qapi_dummy_field_for_empty_struct; }; This silences clang warnings like: ./qapi-types.h:3752:1: warning: empty struct has size 0 in C, size 1 in C++ [-Wextern-c-compat] struct Abort ^ Signed-off-by: NPeter Maydell <peter.maydell@linaro.org> Reviewed-by: NEric Blake <eblake@redhat.com> Message-id: 1419359069-16611-1-git-send-email-peter.maydell@linaro.org

The ioreq-server API added to Xen 4.5 offers better security than the existing Xen/QEMU interface because the shared pages that are used to pass emulation request/results back and forth are removed from the guest's memory space before any requests are serviced. This prevents the guest from mapping these pages (they are in a well known location) and attempting to attack QEMU by synthesizing its own request structures. Hence, this patch modifies configure to detect whether the API is available, and adds the necessary code to use the API if it is.
