usb-storage: Accept 8020i-protocol commands longer than 12 bytes
commit
2f640bf4c94324aeaa1b6385c10aab8c5ad1e1cf upstream.
The 8020i protocol (also 8070i and QIC-157) uses 12-byte commands;
shorter commands must be padded. Simon Detheridge reports that his
3-TB USB disk drive claims to use the 8020i protocol (which is
normally meant for ATAPI devices like CD drives), and because of its
large size, the disk drive requires the use of 16-byte commands.
However the usb_stor_pad12_command() routine in usb-storage always
sets the command length to 12, making the drive impossible to use.
Since the SFF-8020i specification allows for 16-byte commands in
future extensions, we may as well accept them. This patch (as1490)
changes usb_stor_pad12_command() to leave commands larger than 12
bytes alone rather than truncating them.

Fix for ftdi_set_termios() glitching output
ftdi_set_termios() is constantly setting the baud rate, data bits and parity
unnecessarily on every call, . When called while characters are being
transmitted can cause the FTDI chip to corrupt the serial port bit stream
output by stalling the output half a bit during the output of a character.
Simple fix by skipping this setting if the baud rate/data bits/parity are
unchanged.

mm: avoid null pointer access in vm_struct via /proc/vmallocinfo
commit
f5252e009d5b87071a919221e4f6624184005368 upstream
The /proc/vmallocinfo shows information about vmalloc allocations in vmlist
that is a linklist of vm_struct. It, however, may access pages field of
vm_struct where a page was not allocated. This results in a null pointer
access and leads to a kernel panic.
Why this happen:
In __vmalloc_node() called from vmalloc(), newly allocated vm_struct
is added to vmlist at __get_vm_area_node() and then, some fields of
vm_struct such as nr_pages and pages are set at __vmalloc_area_node(). In
other words, it is added to vmlist before it is fully initialized. At the
same time, when the /proc/vmallocinfo is read, it accesses the pages field
of vm_struct according to the nr_pages field at show_numa_info(). Thus, a
null pointer access happens.
Patch:
This patch adds newly allocated vm_struct to the vmlist *after* it is fully
initialized. So, it can avoid accessing the pages field with unallocated
page when show_numa_info() is called.

NFS/sunrpc: don't use a credential with extra groups.
commit
dc6f55e9f8dac4b6479be67c5c9128ad37bb491f upstream.
The sunrpc layer keeps a cache of recently used credentials and
'unx_match' is used to find the credential which matches the current
process.
However unx_match allows a match when the cached credential has extra
groups at the end of uc_gids list which are not in the process group list.
So if a process with a list of (say) 4 group accesses a file and gains
access because of the last group in the list, then another process
with the same uid and gid, and a gid list being the first tree of the
gids of the original process tries to access the file, it will be
granted access even though it shouldn't as the wrong rpc credential
will be used.

nl80211: fix overflow in ssid_len

When one of the SSID's length passed in a scan or sched_scan request

Under Xen we need to resume IRQs associated with IPIs early enough

This issue was introduced by

Back ported to 2.6.32 (which lacks syscore support) by calling the relavant

KVM: x86: Reset tsc_timestamp on TSC writes
There is no upstream commit ID for this patch since it is not a straight

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

cfq: Don't allow queue merges for queues that have no process references
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:

cfq: change the meaning of the cfqq_coop flag
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.

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

ubd_file_size() cannot use ubd_dev->cow.file because at this time

plat-mxc: iomux-v3.h: implicitly enable pull-up/down when that's desired
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.

epoll: fix spurious lockdep warnings

epoll can acquire recursively acquire ep->mtx on multiple "struct
eventpoll"s at once in the case where one epoll fd is monitoring another
epoll fd. This is perfectly OK, since we're careful about the lock
ordering, but it causes spurious lockdep warnings. Annotate the recursion
using mutex_lock_nested, and add a comment explaining the nesting rules
for good measure.
Recent versions of systemd are triggering this, and it can also be
demonstrated with the following trivial test program:

int main(void) {
int e1, e2;
struct epoll_event evt = {
.events = EPOLLIN

x86: Fix compilation bug in kprobes' twobyte_is_boostable
commit
315eb8a2a1b7f335d40ceeeb11b9e067475eb881 upstream.
When compiling an i386_defconfig kernel with gcc-4.6.1-9.fc15.i686, I
noticed a warning about the asm operand for test_bit in kprobes'
can_boost. I discovered that this caused only the first long of
twobyte_is_boostable[] to be output.
Jakub filed and fixed gcc PR50571 to correct the warning and this output
issue. But to solve it for less current gcc, we can make kprobes'
twobyte_is_boostable[] non-const, and it won't be optimized out.

Only a single long of twobyte_is_boostable[] is in the object file.

ipr: Always initiate hard reset in kdump kernel
commit
5d7c20b7fa5c6ca19e871b4050e321c99d32bd43 upstream.
During kdump testing I noticed timeouts when initialising each IPR
adapter. While the driver has logic to detect an adapter in an
indeterminate state, it wasn't triggering and each adapter went
through a 5 minute timeout before finally going operational.
Some analysis showed the needs_hard_reset flag wasn't getting set.
We can check the reset_devices kernel parameter which is set by
kdump and force a full reset. This fixes the problem.

xhci-mem.c: Check for ring->first_seg != NULL
commit
0e6c7f746ea99089fb3263709075c20485a479ae upstream.
There are 2 situations wherein the xhci_ring* might not get freed:
- When xhci_ring_alloc() -> xhci_segment_alloc() returns NULL and
we goto the fail: label in xhci_ring_alloc. In this case, the ring
will not get kfreed.
- When the num_segs argument to xhci_ring_alloc is passed as 0 and
we try to free the rung after that.
( This doesn't really happen as of now in the code but we seem to
be entertaining num_segs=0 in xhci_ring_alloc )
This should be backported to kernels as old as 2.6.31.

staging: quatech_usb2: Potential lost wakeup scenario in TIOCMIWAIT
commit
e8df1674d383d2ecc6efa8d7dba74c03aafdfdd7 upstream.
If the usermode app does an ioctl over this serial device by
using TIOCMIWAIT, then the code will wait by setting the current
task state to TASK_INTERRUPTIBLE and then calling schedule().
This will be woken up by the qt2_process_modem_status on URB
completion when the port_extra->shadowMSR is set to the new
modem status.
However, this could result in a lost wakeup scenario due to a race
in the logic in the qt2_ioctl(TIOCMIWAIT) loop and the URB completion
for new modem status in qt2_process_modem_status.
Due to this, the usermode app's task will continue to sleep despite a
change in the modem status.

commit
bf164c58e58328c40ebc597a8ac00cc6840f9703 upstream.
The w83627ehf driver is improperly reporting thermal diode sensors as
type 2, instead of 3. This caused "sensors" and possibly other
monitoring tools to report these sensors as "transistor" instead of
"thermal diode".
Furthermore, diode subtype selection (CPU vs. external) is only
supported by the original W83627EHF/EHG. All later models only support
CPU diode type, and some (NCT6776F) don't even have the register in
question so we should avoid reading from it.

This can result in a buffer write overflow for stack variables with
