There are no remaining conversions in v4l2_compat_ioctl32(), so all the infrastructure for it can be removed, with the only remaining bit being the compat_ioctl32() callback into drivers that implement their own incompatible data structures. Signed-off-by:

There are eight remaining ioctl commands handled by copying incompatible data structures in v4l2_compat_ioctl32(), all of them fairly simple. Change them to instead go through the native ioctl infrastructure and only special-case the data copy. Signed-off-by:

Now that the 'clips' array is accessed by common code in the native ioctl handler, the same can be done for the compat version, greatly simplifying the compat code for these four ioctl commands. [hverkuil: fix: CHECK: Alignment should match open parenthesis] Signed-off-by:
-
Arnd Bergmann authored
The v4l2_format based ioctls can have an indirect pointer to an array of v4l2_clip structures for overlay mode, depending on the 'type' member. There are only five drivers that use the overlay mode and copy the data through the __user pointer. Change the five drivers to use memcpy() instead, and copy the data in common code using the check_array_args() helpers. This allows for a subsequent patch that use the same mechanism for compat ioctl handlers. Note that there is another pointer for a 'bitmap' that is only used in the 'vivid' driver and nowhere else. There is no easy way to use the same trick without adding complexity to the common code, so this remains a __user pointer.

The ioctl commands based on v4l2_buffer have two sets of compat calls, one for native time32 structures, and one for compat structures on 64-bit architectures. Change the compat version to use the same approach as the other simpler one, for both versions of the structure. In an earlier version of the patch, I unified the v4l2_buffer_time32 and v4l2_buffer32_time32 compatibility handling into a single implementation, but that relied on having it all in one file, rather than having the in_compat_syscall() version in v4l2-compat-ioctl32.c.

The v4l2_ext_controls ioctl handlers use an indirect pointer to an incompatible data structure, making the conversion particularly tricky. Moving the compat implementation to use the new v4l2_compat_get_user()/v4l2_compat_put_user() helpers makes it noticeably simpler. In v4l2_compat_get_array_args()/v4l2_compat_put_array_args(), the 'file' argument needs to get passed to determine the exact format, which is a bit unfortunate, as no other conversion needs these.

These seven commands are all compatible and do not need any conversion handlers. The existing ones just copy 32-bit integers around, and those are always compatible. Signed-off-by:
-
Arnd Bergmann authored
The v4l2-compat-ioctl32() currently takes an extra round trip through user space pointers when converting the data structure formats. In particular, this involves using the compat_alloc_user_space() and copy_in_user() helpers that often lead to worse compat handlers compared to using in_compat_syscall() checks when copying the data. The native implementation already gained a simpler method to deal with the conversion for the time32 conversion. Hook into the same places to provide a location for reading and writing user space data from inside of the generic video_usercopy() helper. Hans Verkuil rewrote the video_get_user() function here to simplify the zeroing of the extra input fields and fixed a couple of bugs in the original implementation.

Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.

Commit 453431a5 ("mm, treewide: rename kzfree() to kfree_sensitive()") renamed kzfree() to kfree_sensitive(), but it left a compatibility definition of kzfree() to avoid being too disruptive. Since then a few more instances of kzfree() have slipped in. Just get rid of them and remove the compatibility definition once and for all. Signed-off-by:
