The GLVND layer will destroy all of the vendor handles at the end of each server generation, but the GLX module then tries to re-use the same (now-freed) handle in xorgGlxServerInit at the start of the next generation.
In xorgGlxCloseExtension, explicitly destroy the vendor handle and set it to NULL so that the next call to xorgGlxServerInit will recreate it. --- glx/glxext.c | 13 +++++++------ 1 file changed, 7 insertions(+), 6 deletions(-) diff --git a/glx/glxext.c b/glx/glxext.c index f1355ce..46ff192 100644 --- a/glx/glxext.c +++ b/glx/glxext.c @@ -56,6 +56,7 @@ RESTYPE __glXContextRes; RESTYPE __glXDrawableRes; static DevPrivateKeyRec glxClientPrivateKeyRec; +static GlxServerVendor *glvnd_vendor = NULL; #define glxClientPrivateKey (&glxClientPrivateKeyRec) @@ -317,6 +318,10 @@ GetGLXDrawableBytes(void *value, XID id, ResourceSizePtr size) static void xorgGlxCloseExtension(const ExtensionEntry *extEntry) { + if (glvnd_vendor != NULL) { + glxServer.destroyVendor(glvnd_vendor); + glvnd_vendor = NULL; + } lastGLContext = NULL; } @@ -497,11 +502,9 @@ xorgGlxServerPreInit(const ExtensionEntry *extEntry) return glxGeneration == serverGeneration; } -static GlxServerVendor * +static void xorgGlxInitGLVNDVendor(void) { - static GlxServerVendor *glvnd_vendor = NULL; - if (glvnd_vendor == NULL) { GlxServerImports *imports = NULL; imports = glxServer.allocateServerImports(); @@ -515,13 +518,11 @@ xorgGlxInitGLVNDVendor(void) glxServer.freeServerImports(imports); } } - return glvnd_vendor; } static void xorgGlxServerInit(CallbackListPtr *pcbl, void *param, void *ext) { - GlxServerVendor *glvnd_vendor; const ExtensionEntry *extEntry = ext; int i; @@ -529,7 +530,7 @@ xorgGlxServerInit(CallbackListPtr *pcbl, void *param, void *ext) return; } - glvnd_vendor = xorgGlxInitGLVNDVendor(); + xorgGlxInitGLVNDVendor(); if (!glvnd_vendor) { return; } -- 2.7.4 _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: https://lists.x.org/mailman/listinfo/xorg-devel
