Dan reported the patch 0baa080c75c: "ethoc: use system memory
as buffer" introduced a potential null dereference.
1060 free:
1061 if (priv->dma_alloc)
^^^^^^^^^^^^^^^
priv can be null here.
He also suggested that the error handling is not complete.
This patch fixes the null priv issue and improves resources
releasing in ethoc_probe() and ethoc_remove().

Commit c02db8c6290bb992442fec1407643c94cc414375:
Author: Chris Wright <chrisw@sous-sol.org>
Date: Sun May 16 01:05:45 2010 -0700
Subject: rtnetlink: make SR-IOV VF interface symmetric
adds broken error handling to do_setlink() in net/core/rtnetlink.c. The
problem is the following chunk of code:
if (tb[IFLA_VFINFO_LIST]) {
struct nlattr *attr;
int rem;
nla_for_each_nested(attr, tb[IFLA_VFINFO_LIST], rem) {
if (nla_type(attr) != IFLA_VF_INFO)
----> goto errout;
err = do_setvfinfo(dev, attr);
if (err < 0)
goto errout;
modified = 1;
}
}
which can get to errout without setting err, resulting in the following error:
net/core/rtnetlink.c: In function 'do_setlink':
net/core/rtnetlink.c:904: warning: 'err' may be used uninitialized in this function
Change the code to return -EINVAL in this case. Note that this might not be
the appropriate error though.

reproduce it.

tc_fill_qdisc() should not be called for builtin qdisc, or it
dereference a NULL pointer to get device ifindex.
Fix is to always use tc_qdisc_dump_ignore() before calling
tc_fill_qdisc().

The TASK_SIZE define is used in some places as a limit on the size of
the virtual address space of a process. On non-MMU systems those addresses
used in comparison will be physical addresses, and they could be anywhere
in the 32bit physical address space. So for !CONFIG_MMU systems set the
TASK_SIZE to the maximum physical address.

Commit 8b505ca8e2600eb9e7dd2d6b2682a81717671374 ("serial: 68328serial.c:

resulting 68328serial.c does not compile:

drivers/serial/68328serial.c:1439: error: ‘BAUD_TABLE_SIZE’ undeclared (first use in this function)

Between problems with Kconfig and merging commits from several
different sources, it seems the s5pc100 build's move from plat-s5pc11
has had a few problems.
Since I do not have the trees to rebuild this quickly, the easiest
thing is to simply fix the errors found once the s5pc100_defconfig
actually builds.

Add a little strncpy optimization which can easily cut boot time by 20%.
When the kernel is booting with initramfs, it builds up the filesystem
from a cpio archive by calling strncpy_from_user() via fs/namei.c's
do_getname() on every file in the archive (which can be lots) with a
length of PATH_MAX (1024). This causes the dest of the strncpy to be
padded with many NUL bytes.
This optimization mostly causes these NUL bytes to be padded with a call
to memset() which is already optimized for filling memory quickly, but
the hardware loop helps a little bit as well.
Boot time measured with 'loglevel=0' so UART speed doesn't get in the way.

The IADDR2DTEST() macro had some duplicated logic with bit 11 and some
incorrect comments, so scrub all of that.
In order to verify these aren't a problem (and won't be in the future),
extend the self tests to operate on as much L1 SRAM as possible.

Since 'extern inline' doesn't work correctly in the context of the Linux
kernel (too many overriding defines), move the string functions to normal
lib/ assembly files (like the existing mem funcs). This avoids the forced
inline all over the kernel and allows us to place them constantly in L1.
This also avoids some module failures when gcc inserts calls to string
functions but the kernel build system doesn't fully consult the library
archives.

While the CC pseudo register can be deduced from the ASTAT register, make
sure we set its value correctly instead of always stubbing it out as 0.
GDB itself looks at this pseudo register instead of ASTAT, so we have to
supply the right value.
