| Message-ID | <qkMmu-i6-19@gated-at.bofh.it> |
| In reply to | #1249548 |
4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joe Thornber <ejt@redhat.com>
commit 2bffa1503c5c06192eb1459180fac4416575a966 upstream.
The cleaner policy doesn't make use of the per cache block hint space in
the metadata (unlike the other policies). When switching from the
cleaner policy to mq or smq a NULL pointer crash (in dm_tm_new_block)
was observed. The crash was caused by bugs in dm-cache-metadata.c
when trying to skip creation of the hint btree.
The minimal fix is to change hint size for the cleaner policy to 4 bytes
(only hint size supported).

4.1-stable review patch. If anyone has any objections, please let me know.

From: Junichi Nomura <j-nomura@ce.jp.nec.com>
commit 2a708cff93f1845b9239bc7d6310aef54e716c6a upstream.
__dm_destroy() takes io_barrier SRCU lock (dm_get_live_table) and
suspend_lock in reverse order. Doing so can cause AB-BA deadlock:
__dm_destroy dm_swap_table
---------------------------------------------------
mutex_lock(suspend_lock)
dm_get_live_table()
srcu_read_lock(io_barrier)
dm_sync_table()
synchronize_srcu(io_barrier)
.. waiting for dm_put_live_table()
mutex_lock(suspend_lock)
.. waiting for suspend_lock
Fix this by taking the locks in proper order.

as we've done the copy up for which we needed the freeze-write lock by that

| Message-ID | <qkMPx-19j-25@gated-at.bofh.it> |
| In reply to | #1249548 |
4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Segall <bsegall@google.com>
commit 54d27365cae88fbcc853b391dcd561e71acb81fa upstream.
The optimized task selection logic optimistically selects a new task
to run without first doing a full put_prev_task(). This is so that we
can avoid a put/set on the common ancestors of the old and new task.
Similarly, we should only call check_cfs_rq_runtime() to throttle
eligible groups if they're part of the common ancestry, otherwise it
is possible to end up with no eligible task in the simple task
selection.
Imagine:
/root
/prev /next
/A /B
If our optimistic selection ends up throttling /next, we goto simple
and our put_prev_task() ends up throttling /prev, after which we're
going to bug out in set_next_entity() because there aren't any tasks
left.
Avoid this scenario by only throttling common ancestors.

From: Arnaldo Carvalho de Melo <acme@redhat.com>
commit e8e6d37e73e6b950c891c780745460b87f4755b6 upstream.
When we introduce a new sort key, we need to update the
hists__calc_col_len() function accordingly, otherwise the width
will be limited to strlen(header).
We can't update it when obtaining a line value for a column (for
instance, in sort__srcline_cmp()), because we reset it all when doing a
resort (see hists__output_recalc_col_len()), so we need to, from what is
in the hist_entry fields, set each of the column widths.

| Message-ID | <qkMPy-19j-61@gated-at.bofh.it> |
| In reply to | #1249548 |
4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Torvalds <torvalds@linux-foundation.org>
commit b9a532277938798b53178d5a66af6e2915cb27cf upstream.
As reported by Dmitry Vyukov, we really shouldn't do ipc_addid() before
having initialized the IPC object state. Yes, we initialize the IPC
object in a locked state, but with all the lockless RCU lookup work,
that IPC object lock no longer means that the state cannot be seen.
We already did this for the IPC semaphore code (see commit e8577d1f0329:
"ipc/sem.c: fully initialize sem_array before making it visible") but we
clearly forgot about msg and shm.

| In reply to | #1249548 |
4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kan Liang <kan.liang@intel.com>
commit 601083cffb7cabdcc55b8195d732f0f7028570fa upstream.
print_aggr() fails to print per-core/per-socket statistics after commit
582ec0829b3d ("perf stat: Fix per-socket output bug for uncore events")
if events have differnt cpus. Because in print_aggr(), aggr_get_id needs
index (not cpu id) to find core/pkg id. Also, evsel cpu maps should be
used to get aggregated id.
Here is an example:
Counting events cycles,uncore_imc_0/cas_count_read/. (Uncore event has
cpumask 0,18)
$ perf stat -e cycles,uncore_imc_0/cas_count_read/ -C0,18 --per-core sleep 2
Without this patch, it failes to get CPU 18 result.
Performance counter stats for 'CPU(s) 0,18':
S0-C0 1 7526851 cycles
S0-C0 1 1.05 MiB uncore_imc_0/cas_count_read/
S1-C0 0 <not counted> cycles
S1-C0 0 <not counted> MiB uncore_imc_0/cas_count_read/
With this patch, it can get both CPU0 and CPU18 result.
Performance counter stats for 'CPU(s) 0,18':
S0-C0 1 6327768 cycles
S0-C0 1 0.47 MiB uncore_imc_0/cas_count_read/
S1-C0 1 330228 cycles

| In reply to | #1249548 |
4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adrian Hunter <adrian.hunter@intel.com>
commit b5cabbcbd157a4bf5a92dfc85134999a3b55342d upstream.
A copy of /proc/kcore containing the kernel text can be made to the
buildid cache. e.g.
perf buildid-cache -v -k /proc/kcore
To workaround objdump limitations, a copy is also made when annotating
against /proc/kcore.
The copying process stops working from libelf about v1.62 onwards (the
problem was found with v1.63).
The cause is that a call to gelf_getphdr() in kcore__add_phdr() fails
because additional validation has been added to gelf_getphdr().
The use of gelf_getphdr() is a misguided attempt to get default
initialization of the Gelf_Phdr structure. That should not be
necessary because every member of the Gelf_Phdr structure is
subsequently assigned. So just remove the call to gelf_getphdr().
Similarly, a call to gelf_getehdr() in gelf_kcore__init() can be
removed also.
Committer notes:
Note to stable@kernel.org, from Adrian in the cover letter for this
patchkit:
The "Fix copying of /proc/kcore" problem goes back to v3.13 if you think
it is important enough for stable.

| In reply to | #1249548 |
4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joonsoo Kim <js1304@gmail.com>
commit 03a2d2a3eafe4015412cf4e9675ca0e2d9204074 upstream.
Commit description is copied from the original post of this bug:
http://comments.gmane.org/gmane.linux.kernel.mm/135349
Kernels after v3.9 use kmalloc_size(INDEX_NODE + 1) to get the next
larger cache size than the size index INDEX_NODE mapping. In kernels
3.9 and earlier we used malloc_sizes[INDEX_L3 + 1].cs_size.
However, sometimes we can't get the right output we expected via
kmalloc_size(INDEX_NODE + 1), causing a BUG().
The mapping table in the latest kernel is like:
index = {0, 1, 2 , 3, 4, 5, 6, n}
size = {0, 96, 192, 8, 16, 32, 64, 2^n}
The mapping table before 3.10 is like this:
index = {0 , 1 , 2, 3, 4 , 5 , 6, n}
size = {32, 64, 96, 128, 192, 256, 512, 2^(n+3)}
The problem on my mips64 machine is as follows:
(1) When configured DEBUG_SLAB && DEBUG_PAGEALLOC && DEBUG_LOCK_ALLOC
&& DEBUG_SPINLOCK, the sizeof(struct kmem_cache_node) will be "150",
and the macro INDEX_NODE turns out to be "2": #define INDEX_NODE
kmalloc_index(sizeof(struct kmem_cache_node))
(2) Then the result of kmalloc_size(INDEX_NODE + 1) is 8.
(3) Then "if(size >= kmalloc_size(INDEX_NODE + 1)" will lead to "size
= PAGE_SIZE".
(4) Then "if ((size >= (PAGE_SIZE >> 3))" test will be satisfied and
"flags |= CFLGS_OFF_SLAB" will be covered.
(5) if (flags & CFLGS_OFF_SLAB)" test will be satisfied and will go to
"cachep->slabp_cache = kmalloc_slab(slab_size, 0u)", and the result
here may be NULL while kernel bootup.
(6) Finally,"BUG_ON(ZERO_OR_NULL_PTR(cachep->slabp_cache));" causes the
BUG info as the following shows (may be only mips64 has this problem):
This patch fixes the problem of kmalloc_size(INDEX_NODE + 1) and removes
the BUG by adding 'size >= 256' check to guarantee that all necessary
small sized slabs are initialized regardless sequence of slab size in
mapping table.

4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Chen <peter.chen@freescale.com>
commit 56ffa1d154c7e12af16273f0cdc42690dd05caf5 upstream.
According to spec, there are functional and protocol stalls.
For functional stall, it is for bulk and interrupt endpoints,
below are cases for it:
- Host sends SET_FEATURE request for Set-Halt, the udc driver
needs to set stall, and return true unconditionally.
- The gadget driver may call usb_ep_set_halt to stall certain
endpoints, if there is a transfer in pending, the udc driver
should not set stall, and return -EAGAIN accordingly.
These two kinds of stall need to be cleared by host using CLEAR_FEATURE
request (Clear-Halt).
For protocol stall, it is for control endpoint, this stall will
be set if the control request has failed. This stall will be
cleared by next setup request (hardware will do it).
It fixed usbtest (drivers/usb/misc/usbtest.c) Test 13 "set/clear halt"
test failure, meanwhile, this change has been verified by
USB2 CV Compliance Test and MSC Tests.

| Message-ID | <qkN8S-1wZ-31@gated-at.bofh.it> |
| In reply to | #1249548 |
4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matt Fleming <matt.fleming@intel.com>
commit a5caa209ba9c29c6421292e7879d2387a2ef39c9 upstream.
Beginning with UEFI v2.5 EFI_PROPERTIES_TABLE was introduced
that signals that the firmware PE/COFF loader supports splitting
code and data sections of PE/COFF images into separate EFI
memory map entries. This allows the kernel to map those regions
with strict memory protections, e.g. EFI_MEMORY_RO for code,
EFI_MEMORY_XP for data, etc.
Unfortunately, an unwritten requirement of this new feature is
that the regions need to be mapped with the same offsets
relative to each other as observed in the EFI memory map. If
this is not done crashes like this may occur,
BUG: unable to handle kernel paging request at fffffffefe6086dd
IP: [<fffffffefe6086dd>] 0xfffffffefe6086dd
Call Trace:
[<ffffffff8104c90e>] efi_call+0x7e/0x100
[<ffffffff81602091>] ? virt_efi_set_variable+0x61/0x90
[<ffffffff8104c583>] efi_delete_dummy_variable+0x63/0x70

[<ffffffff81f37495>] x86_64_start_reservations+0x2a/0x2c
[<ffffffff81f37582>] x86_64_start_kernel+0xeb/0xef
Here 0xfffffffefe6086dd refers to an address the firmware
expects to be mapped but which the OS never claimed was mapped.
The issue is that included in these regions are relative
addresses to other regions which were emitted by the firmware
toolchain before the "splitting" of sections occurred at
runtime.
Needless to say, we don't satisfy this unwritten requirement on
x86_64 and instead map the EFI memory map entries in reverse
order. The above crash is almost certainly triggerable with any
kernel newer than v3.13 because that's when we rewrote the EFI
runtime region mapping code, in commit d2f7cbe7b26a ("x86/efi:
Runtime services virtual mapping"). For kernel versions before
v3.13 things may work by pure luck depending on the
fragmentation of the kernel virtual address space at the time we
map the EFI regions.
Instead of mapping the EFI memory map entries in reverse order,
where entry N has a higher virtual address than entry N+1, map
them in the same order as they appear in the EFI memory map to
preserve this relative offset between regions.
This patch has been kept as small as possible with the intention
that it should be applied aggressively to stable and
distribution kernels. It is very much a bugfix rather than
support for a new feature, since when EFI_PROPERTIES_TABLE is
enabled we must map things as outlined above to even boot - we
have no way of asking the firmware not to split the code/data
regions.
In fact, this patch doesn't even make use of the more strict
memory protections available in UEFI v2.5. That will come later.

| Message-ID | <qkN8S-1wZ-25@gated-at.bofh.it> |
| In reply to | #1249548 |
4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Howells <dhowells@redhat.com>
commit 4bacc9c9234c7c8eec44f5ed4e960d9f96fa0f01 upstream.
Make file->f_path always point to the overlay dentry so that the path in
/proc/pid/fd is correct and to ensure that label-based LSMs have access to the
overlay as well as the underlay (path-based LSMs probably don't need it).
Using my union testsuite to set things up, before the patch I see:
[root@andromeda union-testsuite]# bash 5</mnt/a/foo107
[root@andromeda union-testsuite]# ls -l /proc/$$/fd/
...
lr-x------. 1 root root 64 Jun 5 14:38 5 -> /a/foo107
[root@andromeda union-testsuite]# stat /mnt/a/foo107
...
Device: 23h/35d Inode: 13381 Links: 1
...
[root@andromeda union-testsuite]# stat -L /proc/$$/fd/5
...
Device: 23h/35d Inode: 13381 Links: 1
...
After the patch:
[root@andromeda union-testsuite]# bash 5</mnt/a/foo107
[root@andromeda union-testsuite]# ls -l /proc/$$/fd/
...
lr-x------. 1 root root 64 Jun 5 14:22 5 -> /mnt/a/foo107
[root@andromeda union-testsuite]# stat /mnt/a/foo107
...
Device: 23h/35d Inode: 40346 Links: 1
...
[root@andromeda union-testsuite]# stat -L /proc/$$/fd/5
...
Device: 23h/35d Inode: 40346 Links: 1
...
Note the change in where /proc/$$/fd/5 points to in the ls command. It was
pointing to /a/foo107 (which doesn't exist) and now points to /mnt/a/foo107
(which is correct).
The inode accessed, however, is the lower layer. The union layer is on device
25h/37d and the upper layer on 24h/36d.

commit fc2ca674470bbfe11d72a20a3f19fd3dc43bfca0 upstream.
Commit 3adeb2566b9b ("MIPS: Loongson: Improve LEFI firmware interface")
made the number of UARTs dynamic if LEFI_FIRMWARE_INTERFACE is configured.
Unfortunately, it did not initialize the number of UARTs if
LEFI_FIRMWARE_INTERFACE is not configured. As a result, the Fulong2e
system has no console.

------------------
From: Stefan Assmann <sassmann@kpanic.de>
commit 6423fc34160939142d72ffeaa2db6408317f54df upstream.
During driver probing the following code path is triggered.
igb_probe
->igb_sw_init
->igb_probe_vfs
->igb_pci_enable_sriov
->igb_sriov_reinit
Doing the SR-IOV re-init is not necessary during probing since we're
starting from scratch. Here we can call igb_enable_sriov() right away.
Running igb_sriov_reinit() during igb_probe() also seems to cause
occasional packet loss on some onboard 82576 NICs. Reproduced on
Dell and HP servers with onboard 82576 NICs.
Example:
Intel Corporation 82576 Gigabit Network Connection [8086:10c9] (rev 01)

4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Lee, Chun-Yi" <joeyli.kernel@gmail.com>
commit e3c41e37b0f4b18cbd4dac76cbeece5a7558b909 upstream.
The original bug is a page fault crash that sometimes happens
on big machines when preparing ELF headers:
BUG: unable to handle kernel paging request at ffffc90613fc9000
IP: [<ffffffff8103d645>] prepare_elf64_ram_headers_callback+0x165/0x260
The bug is caused by us under-counting the number of memory ranges
and subsequently not allocating enough ELF header space for them.
The bug is typically masked on smaller systems, because the ELF header
allocation is rounded up to the next page.
This patch modifies the code in fill_up_crash_elf_data() by using
walk_system_ram_res() instead of walk_system_ram_range() to correctly
count the max number of crash memory ranges. That's because the
walk_system_ram_range() filters out small memory regions that
reside in the same page, but walk_system_ram_res() does not.
Here's how I found the bug:
After tracing prepare_elf64_headers() and prepare_elf64_ram_headers_callback(),
the code uses walk_system_ram_res() to fill-in crash memory regions information
to the program header, so it counts those small memory regions that
reside in a page area.
But, when the kernel was using walk_system_ram_range() in
fill_up_crash_elf_data() to count the number of crash memory regions,
it filters out small regions.
I printed those small memory regions, for example:
kexec: Get nr_ram ranges. vaddr=0xffff880077592258 paddr=0x77592258, sz=0xdc0
Based on the code in walk_system_ram_range(), this memory region
will be filtered out:
pfn = (0x77592258 + 0x1000 - 1) >> 12 = 0x77593
end_pfn = (0x77592258 + 0xfc0 -1 + 1) >> 12 = 0x77593
end_pfn - pfn = 0x77593 - 0x77593 = 0 <=== if (end_pfn > pfn) is FALSE
So, the max_nr_ranges that's counted by the kernel doesn't include
small memory regions - causing us to under-allocate the required space.
That causes the page fault crash that happens in a later code path
when preparing ELF headers.
This bug is not easy to reproduce on small machines that have few
CPUs, because the allocated page aligned ELF buffer has more free
space to cover those small memory regions' PT_LOAD headers.

4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: "Tan, Jui Nee" <jui.nee.tan@intel.com> commit 02bc933ebb59208f42c2e6305b2c17fd306f695d upstream. On Intel Baytrail, there is case when interrupt handler get called, no SPI message is captured. The RX FIFO is indeed empty when RX timeout pending interrupt (SSSR_TINT) happens. Use the BIOS version where both HSUART and SPI are on the same IRQ. Both drivers are using IRQF_SHARED when calling the request_irq function. When running two separate and independent SPI and HSUART application that generate data traffic on both components, user will see messages like below on the console: pxa2xx-spi pxa2xx-spi.0: bad message state in interrupt handler This commit will fix this by first checking Receiver Time-out Interrupt, if it is disabled, ignore the request and return without servicing.

Here is a patch to make speakup-r work again. It broke in 3.6 due to commit 4369c64c79a22b98d3b7eff9d089196cd878a10a "Input: Send events one packet at a time) The problem was that the fakekey.c routine to fake a down arrow no longer functioned properly and putting the input_sync fixed it.
