Hi,
In drivers/isdn/gigaset/capi.c::do_disconnect_req() we will leak the
memory allocated (with kmalloc) to 'b3cmsg' if the call to alloc_skb()
fails.
...
b3cmsg = kmalloc(sizeof(*b3cmsg), GFP_KERNEL);
allocation here ------^
if (!b3cmsg) {
dev_err(cs->dev, "%s: out of memory\n", __func__);
send_conf(iif, ap, skb, CAPI_MSGOSRESOURCEERR);
return;
}
capi_cmsg_header(b3cmsg, ap->id, CAPI_DISCONNECT_B3, CAPI_IND,
ap->nextMessageNumber++,
cmsg->adr.adrPLCI | (1 << 16));
b3cmsg->Reason_B3 = CapiProtocolErrorLayer1;
b3skb = alloc_skb(CAPI_DISCONNECT_B3_IND_BASELEN, GFP_KERNEL);
if (b3skb == NULL) {
dev_err(cs->dev, "%s: out of memory\n", __func__);
send_conf(iif, ap, skb, CAPI_MSGOSRESOURCEERR);
return;
leak here ------^
...
This leak is easily fixed by just kfree()'ing the memory allocated to
'b3cmsg' right before we return. The following patch does that.

Linux would not connect to other router running old version Cisco IOS (12.0).
This is most likely a bug in that version of IOS, since it is fixed
in later versions. As a workaround this patch allows a module parameter
to be set to disable compressing the protocol ID.
See: https://bugzilla.vyatta.com/show_bug.cgi?id=3979
RFC 1990 allows an implementation to formulate MP fragments as if protocol
compression had been negotiated. This allows us to always send compressed
protocol IDs. But some implementations don't accept MP fragments with
compressed protocol IDs. This parameter allows us to interoperate with
them. The default value of the configurable parameter is the same as the
current behavior: protocol compression is enabled. If protocol compression
is disabled we will not send compressed protocol IDs.
This is based on an earlier patch by Bob Gilligan (using a sysctl).
Module parameter is writable to allow for enabling even if ppp
is already loaded for other uses.

A race exists when initializing ueagle-atm devices where the generic atm
device may not yet be created before the driver attempts to initialize
it's PHY signal state, which checks whether the atm device has been
created or not. This often causes the sysfs 'carrier' attribute to be
'1' even though no signal has actually been found.

driver->bind (uea_bind)
uea_boot

atm_dev_register UPDATE_ATM_SIGNAL
UPDATE_ATM_SIGNAL checks whether the ATM device has been created and if
not, will not update the PHY signal state. Because of the race that
does not always happen in time, and the PHY signal state remains
ATM_PHY_SIG_FOUND even though no signal exists.
To fix the race, just create the kthread during initialization, and only
after initialization is complete, start the thread that reboots the
device and initializes PHY state.

Low level drivers may behave differently depending on the current
link->lpm_policy. During ata_eh_set_lpm(), DIPM enable commands are
issued after the successful completion of ap->ops->set_lpm(), which
means that the controller is already in the target state. This causes
DIPM enable commands to be processed with mismatching controller power
state and link->lpm_policy value.
In ahci, link->lpm_policy is used to ignore certain PHY events if LPM
is enabled; however, as DIPM commands are issued with stale
link->lpm_policy, they sometimes end up triggering these conditions
and get aborted leading to LPM configuration failure.
Fix it by updating link->lpm_policy before issuing DIPM enable
commands.

ata_qc_complete() contains special handling for certain commands. For
example, it schedules EH for device revalidation after certain
configurations are changed. These shouldn't be applied to EH
commands but they were.
In most cases, it doesn't cause an actual problem because EH doesn't
issue any command which would trigger special handling; however, ACPI
can issue such commands via _GTF which can cause weird interactions.
Restructure ata_qc_complete() such that EH commands are always passed
on to __ata_qc_complete().

While separating out BMDMA irq handler from SFF, commit c3b28894
(libata-sff: separate out BMDMA irq handler) incorrectly made
__ata_sff_port_intr() consider an IRQ to be an idle one if the host
state was transitioned to HSM_ST_ERR by ata_bmdma_port_intr().
This makes BMDMA drivers ignore IRQs reporting host bus error which
leads to timeouts instead of triggering EH immediately. Fix it by
making __ata_sff_port_intr() consider the IRQ to be an idle one iff
the state is HSM_ST_IDLE. This is equivalent to adding HSM_ST_ERR to
the "break"ing case but less error-prone.

If we are registering an i2c device that has a device tree node like
this real-world example:
rtc@68 {
compatible = "dallas,ds1337";
reg = <0x68>;
};
of_i2c_register_devices() will try to load a module called ds1337.ko.
There is no such module, so it will fail. If we look in modules.alias
we will find entries like these:
.
.
.
alias i2c:ds1339 rtc_ds1307
alias i2c:ds1338 rtc_ds1307
alias i2c:ds1337 rtc_ds1307
alias i2c:ds1307 rtc_ds1307
alias i2c:ds1374 rtc_ds1374
.
.
.
The module we want is really called rtc_ds1307.ko. If we request a
module called "i2c:ds1337", the userspace module loader will do the
right thing (unless it is busybox) and load rtc_ds1307.ko. So we add
the I2C_MODULE_PREFIX to the request_module() string.

The default for non-READ_BACK GPIO regs is to have the clear bits set;
this means that our original errata fix was too simplistic. This
changes it to the following behavior:
- when setting GPIOs, ignore the higher order bits (they're for
clearing, we don't need to care about them).
- when clearing GPIOs, keep all the bits, but unset (via XOR) the
lower order bit that negates the clear bit that we care about. That
is, if we're clearing GPIO 26 (val = 0x04000000), we first XOR what's
currently in the register with 0x0400 (GPIO 26's SET bit), and then
OR that with the GPIO 26's CLEAR bit.

The edge detect status GPIOs function differently from the other atomic
model CS5536 GPIO registers; writing 1 to the high bits clears the GPIO,
but writing 1 to the lower bits also clears the bit.
This means that read-modify-write doesn't actually work for it, so don't
apply the errata here. If a negative edge status gets lost after
resume.. well, we tried our best!

The original code returns 0 on success and 1 on failure. In fact, at
this point, "ret" is already either zero or a negative error code so
we can just return it directly.

If the user-provided len is less than the expected offset, the
IRLMP_ENUMDEVICES getsockopt will do a copy_to_user() with a very large
size value. While this isn't be a security issue on x86 because it will
get caught by the access_ok() check, it may leak large amounts of kernel
heap on other architectures. In any event, this patch fixes it.

Alexey Vlasov found /proc/net/tcp could sometime loop and display
millions of sockets in LISTEN state.
In 2.6.29, when we converted TCP hash tables to RCU, we left two
sk_next() calls in listening_get_next().
We must instead use sk_nulls_next() to properly detect an end of chain.

The taskstats structure is internally aligned on 8 byte boundaries but the
layout of the aggregrate reply, with two NLA headers and the pid (each 4
bytes), actually force the entire structure to be unaligned. This causes
the kernel to issue unaligned access warnings on some architectures like
ia64. Unfortunately, some software out there doesn't properly unroll the
NLA packet and assumes that the start of the taskstats structure will
always be 20 bytes from the start of the netlink payload. Aligning the
start of the taskstats structure breaks this software, which we don't
want. So, for now the alignment only happens on architectures that
require it and those users will have to update to fixed versions of those
packages. Space is reserved in the packet only when needed. This ifdef
should be removed in several years e.g. 2012 once we can be confident
that fixed versions are installed on most systems. We add the padding
before the aggregate since the aggregate is already a defined type.
Commit 85893120 ("delayacct: align to 8 byte boundary on 64-bit systems")
previously addressed the alignment issues by padding out the pid field.
This was supposed to be a compatible change but the circumstances
described above mean that it wasn't. This patch backs out that change,
since it was a hack, and introduces a new NULL attribute type to provide
the padding. Padding the response with 4 bytes avoids allocating an
aligned taskstats structure and copying it back. Since the structure
weighs in at 328 bytes, it's too big to do it on the stack.

The current packed struct implementation of unaligned access adds the
packed attribute only to the field within the unaligned struct rather than
to the struct as a whole. This is not sufficient to enforce proper
behaviour on architectures with a default struct alignment of more than
one byte.
For example, the current implementation of __get_unaligned_cpu16 when
compiled for arm with gcc -O1 -mstructure-size-boundary=32 assumes the
struct is on a 4 byte boundary so performs the load of the 16bit packed
field as if it were on a 4 byte boundary:
__get_unaligned_cpu16:
ldrh r0, [r0, #0]
bx lr
Moving the packed attribute to the struct rather than the field causes the
proper unaligned access code to be generated:
__get_unaligned_cpu16:
ldrb r3, [r0, #0] @ zero_extendqisi2
ldrb r0, [r0, #1] @ zero_extendqisi2
orr r0, r3, r0, asl #8
bx lr

When I added led_blink_set I had a typo: the return value of the hw
offload is a regular error code that is zero when succesful, and in that
case software emulation should not be used, rather than the other way
around.
