commit 1cd9f0976aa4606db8d6e3dc3edd0aca8019372a upstream.
This doesn't make much sense, and it exposes a bug in the kernel where
attempts to create a new file in an append-only directory using
O_CREAT will fail (but still leave a zero-length file). This was
discovered when xfstests #79 was generalized so it could run on all
file systems.

Does not corrispond with a direct commit in Linus's tree as it was fixed
differently in the 3.0 release.
We will meet with a BUG_ON() if following script is run.
mkfs.ext4 -b 4096 /dev/sdb1 1000000
mount -t ext4 /dev/sdb1 /mnt/sdb1
fallocate -l 100M /mnt/sdb1/test

for((i=0;i<170;i++))
do
dd if=/dev/zero of=/mnt/sdb1/test conv=notrunc bs=256k count=1

The reason is that it forgot to mark dirty when splitting two extents in
ext4_ext_convert_to_initialized(). Althrough ex has been updated in
memory, it is not dirtied both in ext4_ext_convert_to_initialized() and
ext4_ext_insert_extent(). The disk layout is corrupted. Then it will
meet with a BUG_ON() when writting at the start of that extent again.

commit 53b0f08042f04813cd1a7473dacd3edfacb28eb3 upstream.
Ben Pfaff reported a kernel oops and provided a test program to
reproduce it.
https://kerneltrap.org/mailarchive/linux-netdev/2010/5/21/6277805
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().

commit 57a27e1d6a3bb9ad4efeebd3a8c71156d6207536 upstream.
When one of the SSID's length passed in a scan or sched_scan request
is larger than 255, there will be an overflow in the u8 that is used
to store the length before checking. This causes the check to fail
and we overrun the buffer when copying the SSID.
Fix this by checking the nl80211 attribute length before copying it to
the struct.
This is a follow up for the previous commit
208c72f4fe44fe09577e7975ba0e7fa0278f3d03, which didn't fix the problem
entirely.

commit 7ac28817536797fd40e9646452183606f9e17f71 upstream.
A remote user can provide a small value for the command size field in
the command header of an l2cap configuration request, resulting in an
integer underflow when subtracting the size of the configuration request
header. This results in copying a very large amount of data via
memcpy() and destroying the kernel heap. Check for underflow.

if the rpcbind request fails, or the server keeps returning garbage, we

commit 9bab0b7fbaceec47d32db51cd9e59c82fb071f5a upstream
This adds a mechanism to resume selected IRQs during syscore_resume
instead of dpm_resume_noirq.
Under Xen we need to resume IRQs associated with IPIs early enough
that the resched IPI is unmasked and we can therefore schedule
ourselves out of the stop_machine where the suspend/resume takes
place.
This issue was introduced by 676dc3cf5bc3 "xen: Use IRQF_FORCE_RESUME".
Back ported to 2.6.32 (which lacks syscore support) by calling the relavant
resume function directly from sysdev_resume).

There is no upstream commit ID for this patch since it is not a straight
backport from upstream. It is a fix only relevant to 2.6.32.y.
Since 1d5f066e0b63271b67eac6d3752f8aa96adcbddb from 2.6.37 was
back-ported to 2.6.32.40 as ad2088cabe0fd7f633f38ba106025d33ed9a2105,
the following patch is needed to add the needed reset logic to 2.6.32 as
well.
Bug #23257: Reset tsc_timestamp on TSC writes
vcpu->last_guest_tsc is updated in vcpu_enter_guest() and kvm_arch_vcpu_put()
by getting the last value of the TSC from the guest.
On reset, the SeaBIOS resets the TSC to 0, which triggers a bug on the next
call to kvm_write_guest_time(): Since vcpu->hw_clock.tsc_timestamp still
contains the old value before the reset, "max_kernel_ns = vcpu->last_guest_tsc
- vcpu->hw_clock.tsc_timestamp" gets negative. Since the variable is u64, it
gets translated to a large positive value.
[9333.197080]
vcpu->last_guest_tsc =209_328_760_015 ←
vcpu->hv_clock.tsc_timestamp=209_328_708_109
vcpu->last_kernel_ns =9_333_179_830_643
kernel_ns =9_333_197_073_429
max_kernel_ns =9_333_179_847_943 ←
[9336.910995]
vcpu->last_guest_tsc =9_438_510_584 ←
vcpu->hv_clock.tsc_timestamp=211_080_593_143
vcpu->last_kernel_ns =9_333_763_732_907
kernel_ns =9_336_910_990_771
max_kernel_ns =6_148_296_831_006_663_830 ←
For completeness, here are the values for my 3 GHz CPU:
vcpu->hv_clock.tsc_shift =-1
vcpu->hv_clock.tsc_to_system_mul =2_863_019_502
This makes the guest kernel crawl very slowly when clocksource=kvmclock is
used: sleeps take way longer than expected and don't match wall clock any more.
The times printed with printk() don't match real time and the reboot often
stalls for long times.
In linux-git this isn't a problem, since on every MSR_IA32_TSC write
vcpu->arch.hv_clock.tsc_timestamp is reset to 0, which disables above logic.
The code there is only in arch/x86/kvm/x86.c, since much of the kvm-clock
related code has been refactured for 2.6.37:
99e3e30a arch/x86/kvm/x86.c
(Zachary Amsden 2010-08-19 22:07:17 -1000 1084)
vcpu->arch.hv_clock.tsc_timestamp = 0;

commit c10b61f0910466b4b99c266a7d76ac4390743fb5 upstream.
Hi,
A user reported a kernel bug when running a particular program that did
the following:
created 32 threads
- each thread took a mutex, grabbed a global offset, added a buffer size
to that offset, released the lock
- read from the given offset in the file
- created a new thread to do the same
- exited
The result is that cfq's close cooperator logic would trigger, as the
threads were issuing I/O within the mean seek distance of one another.
This workload managed to routinely trigger a use after free bug when
walking the list of merge candidates for a particular cfqq
(cfqq->new_cfqq). The logic used for merging queues looks like this:
static void cfq_setup_merge(struct cfq_queue *cfqq, struct cfq_queue *new_cfqq)
{
int process_refs, new_process_refs;
struct cfq_queue *__cfqq;
/* Avoid a circular list and skip interim queue merges */
while ((__cfqq = new_cfqq->new_cfqq)) {
if (__cfqq == cfqq)
return;
new_cfqq = __cfqq;
}
process_refs = cfqq_process_refs(cfqq);
/*
* If the process for the cfqq has gone away, there is no
* sense in merging the queues.
*/
if (process_refs == 0)
return;
/*
* Merge in the direction of the lesser amount of work.
*/
new_process_refs = cfqq_process_refs(new_cfqq);
if (new_process_refs >= process_refs) {
cfqq->new_cfqq = new_cfqq;
atomic_add(process_refs, &new_cfqq->ref);
} else {
new_cfqq->new_cfqq = cfqq;
atomic_add(new_process_refs, &cfqq->ref);
}
}
When a merge candidate is found, we add the process references for the
queue with less references to the queue with more. The actual merging
of queues happens when a new request is issued for a given cfqq. In the
case of the test program, it only does a single pread call to read in
1MB, so the actual merge never happens.
Normally, this is fine, as when the queue exits, we simply drop the
references we took on the other cfqqs in the merge chain:
/*
* If this queue was scheduled to merge with another queue, be
* sure to drop the reference taken on that queue (and others in
* the merge chain). See cfq_setup_merge and cfq_merge_cfqqs.
*/
__cfqq = cfqq->new_cfqq;
while (__cfqq) {
if (__cfqq == cfqq) {
WARN(1, "cfqq->new_cfqq loop detected\n");
break;
}
next = __cfqq->new_cfqq;
cfq_put_queue(__cfqq);
__cfqq = next;
}
However, there is a hole in this logic. Consider the following (and
keep in mind that each I/O keeps a reference to the cfqq):
q1->new_cfqq = q2 // q2 now has 2 process references
q3->new_cfqq = q2 // q2 now has 3 process references
// the process associated with q2 exits
// q2 now has 2 process references
// queue 1 exits, drops its reference on q2
// q2 now has 1 process reference
// q3 exits, so has 0 process references, and hence drops its references
// to q2, which leaves q2 also with 0 process references
q4 comes along and wants to merge with q3
q3->new_cfqq still points at q2! We follow that link and end up at an
already freed cfqq.
So, the fix is to not follow a merge chain if the top-most queue does
not have a process reference, otherwise any queue in the chain could be
already freed. I also changed the logic to disallow merging with a
queue that does not have any process references. Previously, we did
this check for one of the merge candidates, but not the other. That
doesn't really make sense.
Without the attached patch, my system would BUG within a couple of
seconds of running the reproducer program. With the patch applied, my
system ran the program for over an hour without issues.
This addresses the following bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=16217
Thanks a ton to Phil Carns for providing the bug report and an excellent
reproducer.

commit b3b6d0408c953524f979468562e7e210d8634150 upstream
The flag used to indicate that a cfqq was allowed to jump ahead in the
scheduling order due to submitting a request close to the queue that
just executed. Since closely cooperating queues are now merged, the flag
holds little meaning. Change it to indicate that multiple queues were
merged. This will later be used to allow the breaking up of merged queues
when they are no longer cooperating.

commit df5fe3e8e13883f58dc97489076bbcc150789a21 upstream.
When cooperating cfq_queues are detected currently, they are allowed to
skip ahead in the scheduling order. It is much more efficient to
automatically share the cfq_queue data structure between cooperating processes.
Performance of the read-test2 benchmark (which is written to emulate the
dump(8) utility) went from 12MB/s to 90MB/s on my SATA disk. NFS servers
with multiple nfsd threads also saw performance increases.

ubd_file_size() cannot use ubd_dev->cow.file because at this time
ubd_dev->cow.file is not initialized.
Therefore, ubd_file_size() will always report a wrong disk size when

Reading from /dev/ubd* would crash the kernel.
We have to read the correct disk size from the COW file's backing
file.

commit 6571534b600b8ca1936ff5630b9e0947f21faf16 upstream.
To configure pads during the initialisation a set of special constants
is used, e.g.
#define MX25_PAD_FEC_MDIO__FEC_MDIO IOMUX_PAD(0x3c4, 0x1cc, 0x10, 0, 0, PAD_CTL_HYS | PAD_CTL_PUS_22K_UP)
The problem is that no pull-up/down is getting activated unless both
PAD_CTL_PUE (pull-up enable) and PAD_CTL_PKE (pull/keeper module
enable) set. This is clearly stated in the i.MX25 datasheet and is
confirmed by the measurements on hardware. This leads to some rather
hard to understand bugs such as misdetecting an absent ethernet PHY (a
real bug i had), unstable data transfer etc. This might affect mx25,
mx35, mx50, mx51 and mx53 SoCs.
It's reasonable to expect that if the pullup value is specified, the
intention was to have it actually active, so we implicitly add the
needed bits.

commit 9bed77ee2fb46b74782d0d9d14b92e9d07f3df6e upstream.
This device is not using the proper demod IF. Instead of using the
IF macro, it is specifying a IF frequency. This doesn't work, as xc3028
needs to load an specific SCODE for the tuner. In this case, there's
no IF table for 5 MHz.

commit d59a7b1dbce8b972ec2dc9fcaaae0bfa23687423 upstream.
If the bus has been reset on resume, set the alternate setting to 0.
This should be the default value, but some devices crash or otherwise
misbehave if they don't receive a SET_INTERFACE request before any other
video control request.
Microdia's 0c45:6437 camera has been found to require this change or it
will stop sending video data after resume.

commit c84c14224bbca6ec60d5851fcc87be0e34df2f44 upstream.
The third parameter of module_param is supposed to be an octal value.
The missing leading "0" causes the following:
$ ls -l /sys/module/carminefb/parameters/
total 0
-rw-rwxr-- 1 root root 4096 Jul 8 08:55 fb_displays
-rw-rwxr-- 1 root root 4096 Jul 8 08:55 fb_mode
-rw-rwxr-- 1 root root 4096 Jul 8 08:55 fb_mode_str
After fixing the perm parameter, we get the expected:
$ ls -l /sys/module/carminefb/parameters/
total 0
-r--r--r-- 1 root root 4096 Jul 8 08:56 fb_displays
-r--r--r-- 1 root root 4096 Jul 8 08:56 fb_mode

Fan Yong <yong.fan@whamcloud.com> noticed setting
FMODE_32bithash wouldn't work with nfsd v4, as
nfsd4_readdir() checks for 32 bit cookies. However, according to RFC 3530
cookies have a 64 bit type and cookies are also defined as u64 in
'struct nfsd4_readdir'. So remove the test for >32-bit values.

commit cbbc719fccdb8cbd87350a05c0d33167c9b79365 upstream.
The parameter's origin type is long. On an i386 architecture, it can
easily be larger than 0x80000000, causing this function to convert it
to a sign-extended u64 type.
Change the type to unsigned long so we get the correct result.

Due to post-increment in condition of kmod_loop_msg in __request_module(),
the system log can be spammed by much more than 5 instances of the 'runaway
loop' message if the number of events triggering it makes the kmod_loop_msg
to overflow.
Fix that by making sure we never increment it past the threshold.

commit 3687f641307eeff6f7fe31a88dc39db88e89238b upstream.
Some Stellaris evaluation kits have the JTAG/SWD FTDI chip onboard,
and some, like EK-LM3S9B90, come with a separate In-Circuit Debugger
Interface Board. The ICDI board can also be used stand-alone, for
other boards and chips than the kit it came with. The ICDI has both
old style 20-pin JTAG connector and new style JTAG/SWD 10-pin 1.27mm
pitch connector.
Tested with EK-LM3S9B90, where the BD-ICDI board is included.
