| | | | | | | | | gcc 4.8 identifies several places where code of the form memset(x, 0, sizeof(x)); is used incorrectly, meaning that less memory is set to zero than required. Signed-off-by: Michael Young <m.a.young@durham.ac.uk> Committed-by: Keir Fraser <keir@xen.org>

| | | | | | | | | | | | | Those functions will be used to create a "list" of parameters that contain more than just strings. This list is converted by qmp_send to a string to be sent to QEMU. Those functions will be used in the next two patches, so right now there are not compiled.

* libxl: Enable -Wshadow.Ian Campbell2012-09-171-4/+4
| | | | | | | | | | | | | | | | | | | | | | It was convenient to invent $(CFLAGS_LIBXL) to do this. Various renamings to avoid shadowing standard functions: - index(3) - listen(2) - link(2) - abort(3) - abs(3) Reduced the scope of some variables to avoid conflicts. Change to libxc is due to the nested hypercall buf macros in set_xen_guest_handle (used in libxl) using the same local private vars. Build tested only.

* libxl: introduce libxl_fd_set_nonblock, rationalise _cloexecIan Jackson2012-01-271-1/+2
| | | | | | | | | | | | | | | | | | | | We want a function for setting fds to nonblocking, so introduce one. This is a very similar requirement to that for libxl_fd_set_cloexec, so make it common with that. While we're at it, fix a few deficiences that make this latter function less desirable than it could be: * Change the return from 0/-1 (like a syscall) to a libxl error code * Take a boolean parameter for turning the flag on and off * Log on error (and so, take a ctx for this purpose) Change callers of libxl_fd_set_cloexec to notice errors. (Although, such errors are highly unlikely.)

* libxl: move a lot more includes into libxl_internal.hIan Jackson2012-01-131-3/+1
| | | | | | | | | | | | | | | | | Move a lot of #include <stdfoo.h> from individual files into libxl_internal.h. This helps avoid portability mistakes where necessary system headers are omitted from individual files, and is also of course a convenience when developing. Also add #include "libxl_osdeps.h" /* must come before any other headers */ to the top of most libxl*.c files, so that anyone who adds any headers before libxl_internal.h will put the in the right place.

* libxl: make LIBXL_INIT_GC a statement, not an initialiserIan Jackson2012-01-131-1/+1
| | | | | | | | | | | | | | | | | | | | | 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>
* libxl: Use GC_INIT and GC_FREE everywhereIan Jackson2011-12-121-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | Replace libxl__gc gc = LIBXL_INIT_GC(ctx); ... libxl__free_all(&gc); with GC_INIT(ctx); ... GC_FREE; throughout with a couple of perl runes. We must then adjust uses of the resulting gc for pointerness, which is mostly just replacing all occurrences of "&gc" with "gc". Also a couple of unusual uses of LIBXL_INIT_GC needed to be fixed up by hand. Here are those runes: perl -i -pe 's/\Q libxl__gc gc = LIBXL_INIT_GC(ctx);/ GC_INIT(ctx);/' tools/libxl/*.c perl -i -pe 's/\Q libxl__free_all(&gc);/ GC_FREE;/' tools/libxl/*.c 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>

* libxl: libxl__qmp_migrateAnthony PERARD2011-12-011-0/+109
| | | | | | | | | | | | This command works in two steps. First, a fd is sent to QEMU through the QMP socket.

QMP stands for QEMU Monitor Protocol and it is used to query information from QEMU or to control QEMU. This implementation will ask QEMU the list of chardevice and store the path to serial ports in xenstored. So we will be able to use xl console with QEMU upstream. In order to connect to the QMP server, a socket file is created in /var/run/xen/qmp-libxl-$(domid).
