Enrico Weigelt, metux IT consult	c933897bc9	dix: CreateConnectionBlock(): record number of roots ... When Xinerama is enabled, the number of user-visible roots (screens) isn't equal to number of actual server screens anymore. Instead of having #ifdef's in several places, let the connection block renderer record the number of roots actually processed.

Enrico Weigelt, metux IT consult	eb9a108624	render: fix glyph Picture/Pixmap leak on ProcRenderAddGlyphs bail path ... The bail: path freed a newly-realized (!found) glyph with a raw '--refcnt; free(glyph)' instead of FreeGlyph(), skipping FreeGlyphPicture()'s release of the glyph's per-screen Picture/Pixmap (created earlier in the same function via CreatePicture()/CreatePixmap(), attached via SetGlyphPicture()). Trigger: send X_RenderAddGlyphs with >= 2 glyphs where an earlier glyph is well-formed (gets fully realized) and a later one is malformed (e.g. declares more bitmap bytes than present, hitting the BadLength/goto bail above) -- the earlier glyph's Picture/Pixmap leaks every such request, repeatable unbounded-leak DoS. No OOM needed. Fix: call FreeGlyph() instead, for both found and !found glyphs -- it already does the right thing for each: a bare refcnt-- for a found glyph (matching the old behavior), and the full teardown (hash removal if present, FreeGlyphPicture(), free the struct) for a !found one. Safe to call on a glyph never added to the global hash yet (AddGlyph() only runs on the success path below): the hash lookup keys off this glyph's own sha1 and simply finds an empty slot to not remove. Found via a fleet-directed alloc-fail/UAF sweep of Xext/, not from a live crash report. Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net>	2026-08-24 13:42:01 +02:00
