2005-02-08Close a race which could allow for privilege escalation by users with DRIEric Anholt
privileges on Radeon hardware. Essentially, a malicious program could submit a packet containing an offset (possibly in main memory) to be rendered from/to, while a separate thread switched that offset in userspace rapidly between a valid value and an invalid one. radeon_check_and_fixup_offset() would pull the offset in from user space, check it, and spit it back out to user space to be copied in later by the emit code. It would sometimes catch the bad value, but sometimes the malicious program could modify it after the check and get an invalid offset rendered from/to. Fix this by allocating a temporary buffer and copying the data in at once. While here, make the cliprects stuff not do the VERIFYAREA_READ and COPY_FROM_USER_UNCHECKED gymnastics, avoiding a lock order reversal on FreeBSD. Performance impact is negligible -- no difference on r200 to ~1% improvement on rv200 in quake3 tests (P4 1Ghz, demofour at 1024x768, n=4 or 5).
2005-02-07Invalid bound check of driver defined ioctls in drm_ioctlDave Airlie
Bug 2489 Reporter: Aapo Tahkola <aet@rasterburn.org>
2005-02-07change DRIVER_ to CORE_ makes things look nicer, also change it so theDave Airlie
driver name is marked on resource allocations
2005-02-07fix agp detection on linuxDave Airlie
2005-02-05- Implement drm_initmap, and extend it with the resource number to helpEric Anholt
FreeBSD. Add drm_get_resource_{start|len} so linux-specific stuff doesn't need to be in shared code. - Fix mach64 build by using __DECONST to work around passing a const pointer to useracc, which is unfortunately not marked const. - Get rid of a lot of maplist code by not having dev->maplist be a pointer, and by sticking the link entries directly in drm_local_map_t rather than having a separate structure for the linked list. - Factor out map uninit and removal into its own routine, rather than duplicating in both drm_takedown() and drm_rmmap(). - Hook up more driver functions, and correct FreeBSD-specific bits of radeon_cp.c, making radeon work. - Baby steps towards using bus_space as we should.

2005-01-16remove duplicate drm_sysfs.oDave Airlie
2005-01-16The patch makes drmAddBufs/drmMapBufs can handle buffers in video memoryDave Airlie
The attached patch adds a new buffer type DRM_FB_BUFFER. It works like AGP memory but uses video memory. From: austinyuan@viatech.com.cn (fd.o bug 1668) Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-01-15Setup MTRRs for frame buffer and aperture manually on Savage3D andFelix Kuehling
Savage4-based cards. Automatic setup in drm_initmap doesn't work due to the weird alignment and size of the aperture.
2005-01-12Use virt_to_page instead of vmalloc_to_page in drm_do_vm_shm_nopage forFelix Kuehling
consistent pages allocated with drm_pci_alloc.
2005-01-09Adjust 4 level page check for <= 2.6.10Jon Smirl
2005-01-07via updates: moved the verifier state struct to dev_priv. Implemented AGPThomas Hellstrom
alignment check.
2005-01-06Adjust drm-memory for 4 level page tables in 2.6.10 ifdef'd to use 3 levelsJon Smirl
in kernels older than 2.6.10
2005-01-01Completeley rewritten Savage DRM which can be considered secure (moduloFelix Kuehling
implementation errors). Direct hardware (MMIO, BCI) access is no longer needed in the Mesa driver. Bumped version to 2.0.0. Corresponding changes to the DDX and Mesa drivers are being committed.
2005-01-01Added a new DRM map type _DRM_CONSISTENT for consistent PCI memory. It usesFelix Kuehling
drm_pci_alloc/free for allocating/freeing the memory. Only implemented in the Linux DRM so far.

From: Stefan Dirsch <sndirsch@suse.de> Signed-off-by: Dave Airlie <airlied@linux.ie>
2004-12-07Patch from Jon Smirl from Nov. 2nd that makes older X servers behave wellThomas Hellstrom
with linux-core. Without this, they will fail on their second invocation since the drm already has a busID assigned. Submitted by: Jon Smirl
2004-12-03Added 3D functionality to the via command verifier. Modified the viaThomas Hellstrom
ring-buffer code somewhat to workaround hardware problems. Bumped via minor version number.
2004-11-11patch from bug 1803 - will try and push to kernel soonDave Airlie

2004-11-09make linux-core build againJon Smirl
2004-11-06Convert more drivers for bsd-core, moving the ioctl definitions to sharedEric Anholt
code. Remove the "drv" from sisdrv, as it's unnecessary. Use the drm_pci functions in i915 instead of per-os implementations of the same. Avoid whitespace within fields in drm_pciids.txt (one of the r300 definitions), since it breaks the bsd pciids script. Tested on sis, mga, r128. i915 needs more work.
2004-11-06Fix Linux build. Why won't this complile? extern int const foo; staticJon Smirl
struct drm_driver driver = { .var = foo }; error says foo is not constant
2004-11-06Commit WIP of BSD conversion to core model. Compiles for r128, radeon, butEric Anholt
doesn't run yet. Moves the ioctl definitions for these two drivers back to the shared code -- they aren't OS-specific.
2004-11-05Move ati_pcigart shared routines into drm-core moduleJon Smirl
2004-10-31Allow drivers to override reclaim_buffers in an OS-independent way byFelix Kuehling

2004-10-20Switch linux-core from using dev->pdev->driver->name toJon Smirl
