2017-05-16kill strlen_user()Al Viro1-2/+0
no callers, no consistent semantics, no sane way to use it... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2017-03-29frv: switch to RAW_COPY_USERAl Viro1-34/+23
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2017-03-29frv: switch to use of fixup_exception()Al Viro1-22/+1
Massage frv search_exception_table() to a) taking pt_regs pointer as explicit argument b) updating ->pc on success Simplifies callers a bit and allows to convert to generic extable.h, while we are at it. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2017-03-06uaccess: drop duplicate includes from asm/uaccess.hAl Viro1-1/+0

2017-03-06uaccess: move VERIFY_{READ,WRITE} definitions to linux/uaccess.hAl Viro1-3/+0

2016-09-28frv: move HAVE_ARCH_UNMAPPED_AREA to pgtable.hAl Viro1-2/+0
it has no business in uaccess.h, everything else has it in pgtable.h and the only user (mm/mmap.c) unconditionally pulls asm/pgtable.h via linux/mm.h. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2016-09-14frv: fix clear_user()Al Viro1-3/+9
It should check access_ok(). Otherwise a bunch of places turn into trivially exploitable rootholes. Cc: stable@vger.kernel.org Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2013-05-28frv: uaccess s/might_sleep/might_fault/Michael S. Tsirkin1-2/+2
The only reason uaccess routines might sleep is if they fault. Make this explicit. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Peter Zijlstra <peterz@infradead.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1369577426-26721-3-git-send-email-mst@redhat.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
2010-04-07frv: fix kernel/user segment handling in NOMMU modeDavid Howells1-2/+0
In NOMMU mode, the FRV segment handling is broken because KERNEL_DS == USER_DS. This causes tests of the following sort: /* don't pin down non-user-based iovecs */ if (segment_eq(get_fs(), KERNEL_DS)) return NULL; to malfunction. To fix this, make USER_DS the top of RAM instead of the top of the non-IO address space, and make KERNEL_DS one more than the top of the non-IO address space. Also get rid of FRV's __addr_ok() as nothing uses it.
