Message-Id: <1433329759-10082-1-git-send-email-fziglio@redhat.com> Date: Wed, 3 Jun 2015 12:09:08 +0100 From: Frediano Ziglio <fziglio@...hat.com> To: fziglio@...hat.com, spice-devel@...ts.freedesktop.org, airlied@...ux.ie, dri-devel@...ts.freedesktop.org, airlied@...hat.com Cc: linux-kernel@...r.kernel.org Subject: [PATCH 00/11 v2] Miscellaneous stability patches This set of patches mainly contains fix for some memory issues using quite aggressively surfaces and other minor problems like images going black after a while. There are no code change from v1, changes: - fix path prefix - rebased on drm-next branch; - add "drm/qxl" prefix on subject; - add reviewed by. About which patches should be applied surely (attempting to put a priority) - "Move main reference counter to GEM object instead of TTM ones" this can causes memory corruption even not wanting to; - "Avoid double free on error" this can be cause leaks in kernel if user space wants, mitigated by the fact that usually DRM inodes are owned by root; - "Handle all errors in qxl_surface_evict" could cause corruption too, not really probable but taking into account that Xorg implementation use a lot signals is not so impossible; - "Handle correctly failures in qxl_alloc_relase_reserved", "Do not leak memory if qxl_release_list_add fails" just cause leaks on situation where memory is already REALLY low, can be omitted; - "Fix print statement not using uninitialized variable", "Remove format string errors" should just print garbage and debugging is disabled by default, not necessary. Frediano Ziglio (11): drm/qxl: Do not cause spice-server to clean our objects drm/qxl: Do not leak memory if qxl_release_list_add fails drm/qxl: Fix print statement not using uninitialized variable drm/qxl: Avoid double free on error drm/qxl: Handle all errors in qxl_surface_evict drm/qxl: Fix return for qxl_release_alloc drm/qxl: Handle correctly failures in qxl_alloc_relase_reserved drm/qxl: Remove format string errors drm/qxl: Move main reference counter to GEM object instead of TTM ones drm/qxl: Simplify cleaning qxl processing command drm/qxl: Propagate correctly errors from qxlhw_handle_to_bo drivers/gpu/drm/qxl/qxl_cmd.c | 11 +++++----- drivers/gpu/drm/qxl/qxl_display.c | 2 +- drivers/gpu/drm/qxl/qxl_drv.h | 2 +- drivers/gpu/drm/qxl/qxl_gem.c | 10 +++++++-- drivers/gpu/drm/qxl/qxl_ioctl.c | 46 +++++++++++++++------------------------ drivers/gpu/drm/qxl/qxl_object.c | 11 ++++------ drivers/gpu/drm/qxl/qxl_release.c | 13 +++++++---- 7 files changed, 46 insertions(+), 49 deletions(-) -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
