2019-06-21drm/ioctl: Ditch DRM_UNLOCKED except for the legacy vblank ioctlDaniel Vetter1-7/+6
This completes Emil's series of removing DRM_UNLOCKED from modern drivers. It's entirely cargo-culted since we ignore it on non-DRIVER_LEGACY drivers since: commit ea487835e8876abf7ad909636e308c801a2bcda6 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Sep 28 21:42:40 2015 +0200 drm: Enforce unlocked ioctl operation for kms driver ioctls Now justifying why we can do this for legacy drives too (and hence close the source of all the bogus copypasting) is a bit more involved. DRM_UNLOCKED was introduced in: commit ed8b67040965e4fe695db333d5914e18ea5f146f Author: Arnd Bergmann <arnd@arndb.de> Date: Wed Dec 16 22:17:09 2009 +0000 drm: convert drm_ioctl to unlocked_ioctl As a immediate hack to keep i810 happy, which would have deadlocked without this trickery. The old BKL is automatically dropped in schedule(), and hence the i810 vs. mmap_sem deadlock didn't actually cause a real deadlock. But with a mutex it would. The solution was to annotate these as DRM_UNLOCKED and mark i810 unsafe on SMP machines. This conversion caused a regression, because unlike the BKL a mutex isn't dropped over schedule (that thing again), which caused a vblank wait in one thread to block the entire desktop and all its apps. Back then we did vblank scheduling by blocking in the client, awesome isn't it. This was fixed quickly in (ok not so quickly, took 2 years): commit 8f4ff2b06afcd6f151868474a432c603057eaf56 Author: Ilija Hadzic <ihadzic@research.bell-labs.com> Date: Mon Oct 31 17:46:18 2011 -0400 drm: do not sleep on vblank while holding a mutex All the other DRM_UNLOCKED annotations for all the core ioctls was work to reach finer-grained locking for modern drivers. This took years, and culminated in: commit fdd5b877e9ebc2029e1373b4a3cd057329a9ab7a Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sat Dec 10 22:52:54 2016 +0100 drm: Enforce BKL-less ioctls for modern drivers DRM_UNLOCKED was never required by any legacy drivers, except for the vblank_wait IOCTL. Therefore we will not regress these old drivers by going back to where we've been in 2011. For all modern drivers nothing will change. To make this perfectly clear, also add a comment to DRM_UNLOCKED. v2: Don't forget about drm_ioc32.c (Michel).

2017-04-04drm: document drm_ioctl.[hc]Daniel Vetter1-36/+40
Also unify/merge with the existing stuff. I was a bit torn where to put this, but in the end I decided to put all the ioctl/sysfs/debugfs stuff into drm-uapi.rst. That means we have a bit a split with the other uapi related stuff used internally, like drm_file.[hc], but I think overall this makes more sense. If it's too confusing we can always add more cross-links to make it more discoverable. But the auto-sprinkling of links kernel-doc already does seems sufficient. Also for prettier docs and more cross-links, switch the internal defines over to an enum, as usual. v2: Update kerneldoc fro drm_compat_ioctl too (caught by 0day), plus a bit more drive-by polish. v3: Fix typo, spotted by xerpi on irc (Sergi). v4: Add missing space in comment (Neil).

2016-09-19drm: drop obsolete drm_core.hDavid Herrmann1-1/+0
The drm_core.h header contains a set of constants meant to be used throughout DRM. However, as it turns out, they're each used just once and don't bring any benefit. They're also grossly mis-named and lack name-spacing. This patch inlines them, or moves them into drm_internal.h as appropriate: - CORE_AUTHOR and CORE_DESC are inlined into corresponding MODULE_*() macros. It's just confusing having to follow 2 pointers when trying to find the definition of these fields. Grep'ping for MODULE_AUTHOR() should reveal the full information, if there's no strong reason not to. - CORE_NAME, CORE_DATE, CORE_MAJOR, CORE_MINOR, and CORE_PATCHLEVEL are inlined into the sysfs 'version' attribute. They're stripped everywhere else (which is just some printk() statements). CORE_NAME just doesn't make *any* sense, as we hard-code it in many places, anyway. The other constants are outdated and just serve binary-compatibility purposes. Hence, inline them in 'version' sysfs attribute (we might even try dropping it..). - DRM_IF_MAJOR and DRM_IF_MINOR are moved into drm_internal.h as they're only used by the global ioctl handlers. Furthermore, versioning interfaces breaks backports and as such is deprecated, anyway. We just keep them for historic reasons. I doubt anyone will ever modify them again.

2016-09-15drm: Only use compat ioctl for addfb2 on X86/IA64Kristian H. Kristensen1-0/+4
Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an unaligned 64 bit field (modifier). This get packed differently between 32 bit and 64 bit modes on architectures that can handle unaligned 64 bit access (X86 and IA64). Other architectures pack the structs the same and don't need the compat wrapper. Use the same condition for drm_mode_fb_cmd2 as we use for drm_update_draw.

2015-07-03drm: remove redundant code form drm_ioc32.cJarkko Sakkinen1-29/+26
The compat ioctl handler ends up calling access_ok() twice: first indirectly inside compat_alloc_user_space() and then after returning from that function. This patch fixes issue. v2: there were three invalid removals of access_ok() that I've fixed. Also went through all the changes couple of times and verified that access_ok() is only removed when the buffer is allocated with compat_alloc_user_space(). My deepest apologies for this kind of sloppiness! Signed-off-by: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2012-02-03drivers/gpu/drm/drm_ioc32.c: initialize all fieldsJulia Lawall1-1/+2
The c32 structure is allocated on the stack and its idx field is not initialized before copying it to user level. This patch takes the value from the result of the ioctl, as done for the other fields. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Dave Airlie <airlied@redhat.com>
