* configure: Don't allow user-only targets for unknown CPU architecturesPeter Maydell2016-06-261-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the user-only targets, we need to know something about the host CPU architecture even if we are using the TCI interpreter rather than TCG. (In particular user-exec.c has code for handling signals that needs to know about that host's context structures.) Specifically forbid building the user-only targets on unknown CPU architectures, rather than allowing them to configure but then fail when building user-exec.c. This change drops supports for two configurations which were theoretically possible before: * linux-user targets on M68K hosts using TCI * linux-user targets on HPPA hosts using TCI We don't think anybody is actually trying to use these in practice, though: * interpreted TCG on a slow host CPU would be unusably slow * the m68k user-exec.c support is missing is_write detection so guest code which writes to the same page it is executing from was broken (will include any guest program using signals) * HPPA TCG backend support was dropped two and a half years ago with no complaints Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Laurent Vivier <laurent@vivier.eu> Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
* configure: Don't override ARCH=unknown if enabling TCIPeter Maydell2016-06-261-1/+0Star
| | | | | | | | | | | | | | | | | | | | At the moment if configure finds an unknown CPU it will set ARCH to 'unknown', and then later either bail out or set it to 'tci' (depending on whether the user passed configure the --enable-tcg-interpreter switch). This is unnecessarily confusing, because we could be using TCI in two cases: * a known host architecture (in which case ARCH is set to the actual host architecture, like 'i386') * an unknown host architecture (in which case ARCH is set to 'tci') so nothing can rely on ARCH=tci to mean "using TCI". Remove the line setting ARCH, so we leave it as "unknown", which is what the actual situation is.

* block/gluster: prevent data loss after i/o errorJeff Cody2016-04-191-0/+8
| | | | | | | | | | | | | | | | | Upon receiving an I/O error after an fsync, by default gluster will dump its cache. However, QEMU will retry the fsync, which is especially useful when encountering errors such as ENOSPC when using the werror=stop option. When using caching with gluster, however, the last written data will be lost upon encountering ENOSPC. Using the write-behind-cache xlator option of 'resync-failed-syncs-after-fsync' should cause gluster to retain the cached data after a failed fsync, so that ENOSPC and other transient errors are recoverable. Unfortunately, we have no way of knowing if the 'resync-failed-syncs-after-fsync' xlator option is supported, so for now close the fd and set the BDS driver to NULL upon fsync error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Xen 4.2 become unsupported upstream in 09/2015 (see http://wiki.xen.org/wiki/Xen_Release_Features). However as far as the interfaces provided by the toolstack libraries go 4.2 and 4.3 are indistinguishable. Therefore drop support for Xen 4.1 and earlier which removes a whole pile of compatibility code which makes future work (to use stable library interfaces provided by upstream) more difficult. In particular all supported versions now use a pointer as a libxc handle (4.1 and earlier used an integer, resulting in various shim layers). Also Xen 4.2 was the first version of Xen to formally support upstream QEMU (as a preview) so that makes sense as a cut-off now. This change drops all the configure-y and resulting ifdefs in a mostly mechanical way. A follow up will refactor wrappers which are now unused.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Developers on 64-bit machines will often try to perform a 32-bit build of QEMU by running ./configure --extra-cflags="-m32" Unfortunately if PKG_CONFIG_LIBDIR is not set to point to the location of the 32-bit pkg-config files, then configure will silently pick up the 64-bit pkg-config files and still succeed. This causes a problem for glib because it means QEMU will be pulling in /usr/lib64/glib-2.0/include/glibconfig.h instead of /usr/lib/glib-2.0/include/glibconfig.h This causes problems because the 'gsize' type (defined as 'unsigned long') will no longer be fully compatible with the 'size_t' type (defined as 'unsigned int'). Although both are the same size, the compiler refuses to allow casts from 'unsigned long *' to 'unsigned int *' as they are different pointer types. This results in non-obvious compiler errors when building QEMU eg qga/commands-posix.c: In function ‘qmp_guest_set_user_password’: qga/commands-posix.c:1912:55: error: passing argument 2 of ‘g_base64_decode’ from incompatible pointer type [-Werror=incompatible-pointer-types] rawpasswddata = (char *)g_base64_decode(password, &rawpasswdlen); ^ In file included from /usr/include/glib-2.0/glib.h:35:0, from qga/commands-posix.c:14: /usr/include/glib-2.0/glib/gbase64.h:52:9: note: expected ‘gsize * {aka long unsigned int *}’ but argument is of type ‘size_t * {aka unsigned int *}’ guchar *g_base64_decode (const gchar *text, ^ cc1: all warnings being treated as errors To detect this problem, add a check to configure that verifies that GLIB_SIZEOF_SIZE_T matches sizeof(size_t). If this fails print a warning suggesting that the dev probably needs to set PKG_CONFIG_LIBDIR. On Fedora x86_64 it passes with any of: # ./configure # PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig ./configure --extra-cflags="-m32" # PKG_CONFIG_LIBDIR=/usr/lib64/pkgconfig ./configure --extra-cflags="-m64" And fails with a mis-match # PKG_CONFIG_LIBDIR=/usr/lib64/pkgconfig ./configure --extra-cflags="-m32" # PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig ./configure --extra-cflags="-m64" ERROR: sizeof(size_t) doesn't match GLIB_SIZEOF_SIZE_T. You probably need to set PKG_CONFIG_LIBDIR to point to the right pkg-config files for your build target Signed-off-by: Daniel P.

* xen: make it possible to build without the Xen PV domain builderIan Campbell2016-01-261-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | Until the previous patch this relied on xc_fd(), which was only implemented for Xen 4.0 and earlier. Given this wasn't working since Xen 4.0 I have marked this as disabled by default. Removing this support drops the use of a bunch of symbols from libxenctrl, specifically: - xc_domain_create - xc_domain_destroy - xc_domain_getinfo - xc_domain_max_vcpus - xc_domain_setmaxmem - xc_domain_unpause - xc_evtchn_alloc_unbound - xc_linux_build This is another step towards only using Xen libraries which provide a stable inteface.

* xen: Use stable library interfaces when they are available.Ian Campbell2016-01-261-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Xen 4.7 we are refactoring parts libxenctrl into a number of separate libraries which will provide backward and forward API and ABI compatiblity. Specifically libxenevtchn, libxengnttab and libxenforeignmemory. Previous patches have already laid the groundwork for using these by switching the existing compatibility shims to reflect the intefaces to these libraries. So all which remains is to update configure to detect the libraries and enable their use. Although they are notionally independent we take an all or nothing approach to the three libraries since they were added at the same time. The only non-obvious bit is that we now open a proper xenforeignmemory handle for xen_fmem instead of reusing the xen_xc handle. Build tested with 4.0 .. 4.6 (inclusive) and the patches targetting 4.7 which adds these libraries. This uses CONFIG_XEN_CTRL_INTERFACE_VERSION == 471 to cover the introduction of these new interfaces.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately the OpenBSD pdksh does not like brackets inside the right part of a ${variable+word} parameter expansion: $ echo "${a+($b)}" ksh: ${a+($b)}": bad substitution though both bash and dash accept them. In any case this line was causing odd output in the case where nettle is not present: nettle no () (because if nettle is not present then $nettle will be "no", not a null string or unset). Rewrite it to just use an if. This bug was originally introduced in becaeb726 and was present in the 2.4.0 release. Fixes: https://bugs.launchpad.net/qemu/+bug/1525682 Reported-by: Dmitrij D.

* io: add QIOChannelSocket classDaniel P. Berrange2015-12-181-0/+11
| | | | | | | | | | | | | Implement a QIOChannel subclass that supports sockets I/O. The implementation is able to manage a single socket file descriptor, whether a TCP/UNIX listener, TCP/UNIX connection, or a UDP datagram. It provides APIs which can listen and connect either asynchronously or synchronously. Since there is no asynchronous DNS lookup API available, it uses the QIOTask helper for spawning a background thread to ensure non-blocking operation. Signed-off-by: Daniel P.

* configure: use appropriate code fragment for -fstack-protector checksRodrigo Rebello2015-12-041-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | The check for stack-protector support consisted in compiling and linking the test program below (output by function write_c_skeleton()) with the compiler flag -fstack-protector-strong first and then with -fstack-protector-all if the first one failed to work: int main(void) { return 0; } This caused false positives when using certain toolchains in which the compiler accepted -fstack-protector-strong but no support was provided by the C library, since for this stack-protector variant the compiler emits canary code only for functions that meet specific conditions (local arrays, memory references to local variables, etc.) and the code fragment under test included none of them (hence no stack protection code generated, no link failure). This fix changes the test program used for -fstack-protector checks to include a function that meets conditions which cause the compiler to generate canary code in all variants.
