sparc32: nocheck uaccess coding style tweaks

2015-01-13T13:24:14+00:00

Sam Ravnborg suggested packing single-lines cases in switch statements
in nocheck uaccess macros makes for easier to read code.

sparc32: uaccess_32 macro whitespace fixes

2015-01-13T13:23:42+00:00

Macros within arch/sparc/include/asm/uaccess_32.h are made harder to
read because they violate a bunch of coding style rules.

Fix it up.

sparc32/uaccess: fix sparse errors

2015-01-13T13:23:23+00:00

virtio wants to read bitwise types from userspace using get_user.  At the
moment this triggers sparse errors, since the value is passed through an
integer.

Fix that up using __force.

sparc: drop use of extern for prototypes in arch/sparc/include/asm

2014-05-19T02:01:29+00:00

Drop extern for all prototypes and adjust alignment of parameters
as required after the removal.
In a few rare cases adjust linelength to conform to maximum 80 chars,
and likewise in a few rare cases adjust alignment of parameters
to static functions.

sparc: use the new generic strnlen_user() function

2012-05-26T18:33:54+00:00

This throws away the sparc-specific functions in favor of the generic
optimized version.

sparc: Add full proper error handling to strncpy_from_user().

2012-05-23T06:32:27+00:00

Linus removed the end-of-address-space hackery from
fs/namei.c:do_getname() so we really have to validate these edge
conditions and cannot cheat any more (as x86 used to as well).

Move to a common C implementation like x86 did.  And if both
src and dst are sufficiently aligned we'll do word at a time
copies and checks as well.

All sun4/sun4c stuff and unused.

sparc: Kill user copy check code.

2010-08-09T07:45:46+00:00

For whatever reason GCC isn't able to figure things out in
the control flow (in particular when min() and max() expressions
are involved) on sparc as well as it can on x86.

So lots of useless incorrect user copy warnings get spewed and the
full-on compile failure mode of the user copy checks were never usable
on sparc at all.

People can debug these kinds of problems on x86.

sparc: copy_from_user() should not return -EFAULT

2010-01-06T04:41:48+00:00

From: Heiko Carstens 

Callers of copy_from_user() expect it to return the number of bytes
it could not copy. In no case it is supposed to return -EFAULT.

In case of a detected buffer overflow just return the requested
length. In addition one could think of a memset that would clear
the size of the target object.

sparc: Use __builtin_object_size() to validate the buffer size for copy_from_user()

2009-12-11T07:05:23+00:00

This mirrors x86 commit 9f0cf4adb6aa0bfccf675c938124e68f7f06349d
(x86: Use __builtin_object_size() to validate the buffer size for copy_from_user())
