* libxl: fix parse_backend_path and device_backend_path to be mutualRoger Pau Monne2012-01-261-4/+3
| | | | | | | | | | | Currently if libxl__parse_backend_path is used and then you try to get the original path again with libxl__device_backend_path the result is wrong. This patch fixes the issue, so transformation from path to libxl__device and back is reciprocal.

* Update memshr API and toolsAndres Lagar-Cavilla2012-01-268-38/+139
| | | | | | | | | | | | | | | | | | | | | | | This patch is the folded version of API updates, along with the associated tool changes to ensure that the build is always consistent. API updates: - The source domain in the sharing calls is no longer assumed to be dom0. - Previously, the mem sharing code would return an opaque handle to index shared pages (and nominees) in its global hash table. By removing the hash table, the handle becomes a version, to avoid sharing a stale version of a page. Thus, libxc wrappers and tools need to be updated to recall the share functions with the information needed to fetch the page (which they readily have). Tool updates: The only (in-tree, that we know of) consumer of the mem sharing API is the memshr tool. This is updated to use the new API.

* tools/libxc: fix error handling in xc_mem_paging_loadOlaf Hering2012-01-261-5/+10
| | | | | | | | | | | | | | xc_mem_paging_load() does not pass errors in errno and the actual errno from xc_mem_event_control() is overwritten by munlock(). xenpaging_populate_page() needs to check errno, but with the switch to xc_mem_paging_load() it could not receive ENOMEM anymore. Update xc_mem_paging_load() to return -1 and preserve errno during munlock().

* libxl: make LIBXL_INIT_GC a statement, not an initialiserIan Jackson2012-01-132-3/+8
| | | | | | | | | | | | | | | | | | | | | Previously LIBXL_INIT_GC was an initialiser, which you were expected to use like this: libxl__gc gc = LIBXL_INIT_GC(ctx); But we are going to want to put things in the gc which are to be initialised using other macros. That means that LIBXL_INIT_GC has to become a statement too. So instead, we make it so that it's used like this: libxl_gc gc; LIBXL_INIT_GC(gc,ctx); In fact there are only a couple of callers now, including GC_INIT which uses this trick: libxl_gc gc[1]; LIBXL_INIT_GC(gc[0],ctx); Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com> Acked-by: Ian Campbell <ian.campbell@citrix.com> Committed-by: Ian Jackson <Ian.Jackson@eu.citrix.com>
