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.

[Mon 2013-08-19 12:28:35 PM PDT] <headless> it's a known stack corruptor on non-coherent arches
|

|
||||
[Mon 2013-08-19 12:34:11 PM PDT] <DonkeyHotei> headless: explain
|
||||
[Mon 2013-08-19 12:35:38 PM PDT] <headless> usb_control_msg() (or other such func) should not use buffer on stack. DMA from/to stack is prohibited
|
||||
[Mon 2013-08-19 12:35:58 PM PDT] <headless> and EHCI uses DMA on control xfers (as well as all the others)

Subject: [PATCH] lib: devres: Introduce devm_ioremap_resource()
|
||||
|
||||
The devm_request_and_ioremap() function is very useful and helps avoid a
|
||||
whole lot of boilerplate. However, one issue that keeps popping up is
|
||||
its lack of a specific error code to determine which of the steps that
|
||||
it performs failed. Furthermore, while the function gives an example and
|
||||
suggests what error code to return on failure, a wide variety of error
|
||||
codes are used throughout the tree.
|
||||
|
||||
In an attempt to fix these problems, this patch adds a new function that
|
||||
drivers can transition to. The devm_ioremap_resource() returns a pointer
|
||||
to the remapped I/O memory on success or an ERR_PTR() encoded error code
|
||||
on failure. Callers can check for failure using IS_ERR() and determine
|
||||
its cause by extracting the error code using PTR_ERR().
|
||||
|
||||
devm_request_and_ioremap() is implemented as a wrapper around the new
|
||||
API and return NULL on failure as before. This ensures that backwards
|
||||
compatibility is maintained until all users have been converted to the
|
||||
new API, at which point the old devm_request_and_ioremap() function
|
||||
should be removed.
|
||||
|
||||
A semantic patch is included which can be used to convert from the old
|
||||
devm_request_and_ioremap() API to the new devm_ioremap_resource() API.
|
||||
Some non-trivial cases may require manual intervention, though.

Subject: [PATCH 1/2] PCI: Remove __weak annotation from
|
||||
pcibios_get_phb_of_node decl
|
||||
|
||||
The __weak annotation on the pcibios_get_phb_of_node() declaration
|
||||
causes *every* definition to be marked "weak." The linker then
|
||||
selects one based on link order, which may be the wrong one.
|
||||
|
||||
Gabor found that on MIPS, the linker selected the generic implementation
|
||||
from drivers/pci even though arch/mips supplied a definition without the
|
||||
__weak annotation:
|
||||
|
||||
$ mipsel-openwrt-linux-readelf -s arch/mips/pci/built-in.o \
|
||||
drivers/pci/built-in.o vmlinux.o | grep pcibios_get_phb_of_node
|
||||

||||

|
||||
31898: 0017e4ec 104 FUNC WEAK DEFAULT 2 pcibios_get_phb_of_node
|
||||
|
||||
This removes the __weak annotation from the pcibios_get_phb_of_node()
|
||||
declaration so arch-specific non-weak implementations work reliably.

Subject: [PATCH 2/2] MIPS/PCI: Implement pcibios_get_phb_of_node
|
||||
|
||||
The of_node field of the device assigned to a
|
||||
PCI bus is used during scanning of the PCI bus.
|
||||
However on MIPS, the of_node field is assigned
|
||||
only after the bus has been scanned.
|
||||
|
||||
Implement the architecture specific version of
|
||||
'pcibios_get_phb_of_node'. Which ensures that the
|
||||
PCI driver core will initialize the of_node field
|
||||
before starting the scan.
|
||||
|
||||
Also remove the local assignment of bus->dev.of_node,
|
||||
it is not needed after the patch.

Subject: [PATCH] spi/of: Use DT aliases for assigning bus number
|
||||
|
||||
Linux assigns a number to each spi_master in the system, but when the
|
||||
platform used the device tree, the numbers are dynamically assigned and
|
||||
are not predictable. In general this shouldn't matter since the kernel
|
||||
doesn't use the bus number for anything other than matching a bus to
|
||||
spi_boardinfo (not used for DT). However, sometimes userspace needs to
|
||||
figure out which bus is which, so it makes sense to use the global
|
||||
/aliases namespace to choose a specific bus number.
|
||||
|
||||
It is safe to derive the bus number from an alias because aliases will
|
||||
never cause two buses to try and use the same bus number. (At one time
|
||||
the cell-index property was used for this purpose, but cell-index has
|
||||
the risk of an id collision).

Subject: [PATCH] MIPS: decompressor: fix build failure on memcpy() in
|
||||
decompress.c
|
||||
|
||||
The decompress.c file includes linux/kernel.h which causes the following
|
||||
inclusion chain to be pulled:
|
||||
linux/kernel.h ->
|
||||
linux/dynamic_debug.h ->
|
||||
linux/string.h ->
|
||||
asm/string.h
|
||||
|
||||
We end up having a the GCC builtin + architecture specific memcpy() expanding
|
||||
into this:
|
||||
|
||||
void *({ size_t __len = (size_t n); void *__ret; if
|
||||
(__builtin_constant_p(size_t n) && __len >= 64) __ret = memcpy((void *dest),
|
||||
(const void *src), __len); else __ret = __builtin_memcpy((void *dest), (const
|
||||
void *src), __len); __ret; })
|
||||
{
|
||||
[memcpy implementation in decompress.c starts here]
|
||||
int i;
|
||||
const char *s = src;
|
||||
char *d = dest;
|
||||
|
||||
for (i = 0; i < n; i++)
|
||||
d[i] = s[i];
|
||||
return dest;
|
||||
}
|
||||
|
||||
raising the following compilation error:
|
||||
arch/mips/boot/compressed/decompress.c:46:8: error: expected identifier or '('
|
||||
before '{' token
|
||||
|
||||
There are at least three possibilities to fix this issue:
|
||||
|
||||
1) define _LINUX_STRING_H_ at the beginning of decompress.c to prevent
|
||||
further linux/string.h definitions and declarations from being used, and add
|
||||
an explicit strstr() declaration for linux/dynamic_debug.h
|
||||
|
||||
2) remove the inclusion of linux/kernel.h because we actually use no definition
|
||||
or declaration from this header file
|
||||
|
||||
3) undefine memcpy or re-define memcpy to memcpy thus resulting in picking up
|
||||
the local memcpy() implementation to this compilation unit
|
||||
|
||||
This patch uses the second option which is the less intrusive one.

|

|

This patch adds an ignore_oc flag which can be set by EHCI controller
|
||||
not supporting or wanting to disable overcurrent checking. The EHCI
|
||||
platform data in include/linux/usb/ehci_pdriver.h is also augmented to
|

take advantage of this new flag.

MIPS: allow disabling the kernel FPU emulator
|
||||
|
||||
This patch allows turning off the in-kernel Algorithmics
|
||||
FPU emulator support, which allows one to save a couple of
|
||||
precious blocks on an embedded system.

This patch allows the user to specify desired packet types (outgoing,
|

broadcast, unicast, etc.) on packet sockets via setsockopt.
|

This can reduce the load in situations where only a limited number
|

of packet types are necessary
