|
||||
Subject: [PATCH] ARM: 7668/1: fix memset-related crashes caused by recent GCC
|
||||
(4.7.2) optimizations
|
||||
|
||||
Recent GCC versions (e.g. GCC-4.7.2) perform optimizations based on
|
||||
assumptions about the implementation of memset and similar functions.
|
||||
The current ARM optimized memset code does not return the value of
|
||||
its first argument, as is usually expected from standard implementations.
|
||||
|
||||
For instance in the following function:
|
||||
|
||||
void debug_mutex_lock_common(struct mutex *lock, struct mutex_waiter *waiter)
|
||||
{
|
||||
memset(waiter, MUTEX_DEBUG_INIT, sizeof(*waiter));
|
||||
waiter->magic = waiter;
|
||||
INIT_LIST_HEAD(&waiter->list);
|
||||
}
|
||||
|
||||
compiled as:
|
||||
|
||||
800554d0 <debug_mutex_lock_common>:
|
||||
800554d0: e92d4008 push {r3, lr}
|
||||
800554d4: e1a00001 mov r0, r1
|
||||
800554d8: e3a02010 mov r2, #16 ; 0x10
|
||||
800554dc: e3a01011 mov r1, #17 ; 0x11
|
||||
800554e0: eb04426e bl 80165ea0 <memset>
|
||||
800554e4: e1a03000 mov r3, r0
|
||||
800554e8: e583000c str r0, [r3, #12]
|
||||
800554ec: e5830000 str r0, [r3]
|
||||
800554f0: e5830004 str r0, [r3, #4]
|
||||
800554f4: e8bd8008 pop {r3, pc}
|
||||
|
||||
GCC assumes memset returns the value of pointer 'waiter' in register r0; causing
|
||||
register/memory corruptions.
|
||||
|
||||
This patch fixes the return value of the assembly version of memset.
|
||||
It adds a 'mov' instruction and merges an additional load+store into
|
||||
existing load/store instructions.
|
||||
For ease of review, here is a breakdown of the patch into 4 simple steps:
|
||||
|
||||
Step 1
|
||||
======
|
||||
Perform the following substitutions:
|
||||
ip -> r8, then
|
||||
r0 -> ip,
|
||||
and insert 'mov ip, r0' as the first statement of the function.
|
||||
At this point, we have a memset() implementation returning the proper result,
|
||||
but corrupting r8 on some paths (the ones that were using ip).
|
||||
|
||||
Step 2
|
||||
======
|
||||
Make sure r8 is saved and restored when (! CALGN(1)+0) == 1:
|
||||
|
||||
save r8:
|
||||
- str lr, [sp, #-4]!
|
||||
+ stmfd sp!, {r8, lr}
|
||||
|
||||
and restore r8 on both exit paths:
|
||||
- ldmeqfd sp!, {pc} @ Now <64 bytes to go.
|
||||
+ ldmeqfd sp!, {r8, pc} @ Now <64 bytes to go.
|
||||
(...)
|
||||
tst r2, #16
|
||||
stmneia ip!, {r1, r3, r8, lr}
|
||||
- ldr lr, [sp], #4
|
||||
+ ldmfd sp!, {r8, lr}
|
||||
|
||||
Step 3
|
||||
======
|
||||
Make sure r8 is saved and restored when (! CALGN(1)+0) == 0:
|
||||
|
||||
save r8:
|
||||
- stmfd sp!, {r4-r7, lr}
|
||||
+ stmfd sp!, {r4-r8, lr}
|
||||
|
||||
and restore r8 on both exit paths:
|
||||
bgt 3b
|
||||
- ldmeqfd sp!, {r4-r7, pc}
|
||||
+ ldmeqfd sp!, {r4-r8, pc}
|
||||
(...)
|
||||
tst r2, #16
|
||||
stmneia ip!, {r4-r7}
|
||||
- ldmfd sp!, {r4-r7, lr}
|
||||
+ ldmfd sp!, {r4-r8, lr}
|
||||
|
||||
Step 4
|
||||
======
|
||||
Rewrite register list "r4-r7, r8" as "r4-r8".

Subject: [PATCH] ARM: 7670/1: fix the memset fix
|
||||
|
||||
Commit 455bd4c430b0 ("ARM: 7668/1: fix memset-related crashes caused by
|
||||
recent GCC (4.7.2) optimizations") attempted to fix a compliance issue
|
||||
with the memset return value. However the memset itself became broken
|
||||
by that patch for misaligned pointers.
|
||||
|
||||
This fixes the above by branching over the entry code from the
|
||||
misaligned fixup code to avoid reloading the original pointer.
|
||||
|
||||
Also, because the function entry alignment is wrong in the Thumb mode
|
||||
compilation, that fixup code is moved to the end.
|
||||
|
||||
While at it, the entry instructions are slightly reworked to help dual
|
||||
issue pipelines.
