virtio: balloon: leak / fill balloon across S4
|
|
commit e562966dbaf49e7804097cd991e5d3a8934fc148 added support for S4 to
the balloon driver. The freeze function did nothing to free the pages,
since reclaiming the pages from the host to immediately give them back
(if S4 was successful) seemed wasteful. Also, if S4 wasn't successful,
the guest would have to re-fill the balloon. On restore, the pages were
supposed to be marked freed and the free page counters were incremented
to reflect the balloon was totally deflated.
However, this wasn't done right. The pages that were earlier taken away
from the guest during a balloon inflation operation were just shown as
used pages after a successful restore from S4. Just a fancy way of
leaking lots of memory.
Instead of trying that, just leak the balloon on freeze and fill it on
restore/thaw paths. This works properly now. The optimisation to not
leak can be added later on after a bit of refactoring of the code.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
IOMMU fixes for Linux 3.3-rc5
All the fixes are for the OMAP IOMMU driver. The first patch is the
biggest one. It fixes the calls of the function omap_find_iovm_area() in
the omap-iommu-debug module which expects a 'struct device' parameter
since commit fabdbca instead of an omap_iommu handle. The
omap-iommu-debug code still passed the handle to the function which
caused a crash.
The second patch fixes a NULL pointer dereference in the OMAP code and
the third patch makes sure that the omap-iommu is initialized before the
omap-isp driver, which relies on the iommu. The last patch is only a
workaround until defered probing is implemented.

This is a revert of 6aa56062eaba67adfb247cded244fd877329588d.
This was originally introduced to workaround reads of the ringbuffer
registers returning 0 on SandyBridge causing hangs due to ringbuffer
overflow. The root cause here was reads through the GT powerwell require
the forcewake dance, something we only learnt of later. Now it appears
that reading the reported head position from the HWS is returning
garbage, leading once again to hangs.
For example, on q35 the autoreported head reports:
[ 217.975608] head now 00010000, actual 00010000
[ 436.725613] head now 00200000, actual 00200000
[ 462.956033] head now 00210000, actual 00210010
[ 485.501409] head now 00400000, actual 00400020
[ 508.064280] head now 00410000, actual 00410000
[ 530.576078] head now 00600000, actual 00600020
[ 553.273489] head now 00610000, actual 00610018
which appears reasonably sane. In contrast, if we look at snb:
[ 141.970680] head now 00e10000, actual 00008238
[ 141.974062] head now 02734000, actual 000083c8
[ 141.974425] head now 00e10000, actual 00008488
[ 141.980374] head now 032b5000, actual 000088b8
[ 141.980885] head now 03271000, actual 00008950
[ 142.040628] head now 02101000, actual 00008b40
[ 142.180173] head now 02734000, actual 00009050
[ 142.181090] head now 00000000, actual 00000ae0
[ 142.183737] head now 02734000, actual 00009050
In addition, the automatic reporting of the head position is scheduled
to be defeatured in the future. It has no more utility, remove it.

omap3isp depends on omap's iommu and will fail to probe if
initialized before it (which always happen if they are builtin).
Make omap's iommu subsys_initcall as an interim solution until
the probe deferral mechanism is merged.

future for this driver as well.
6) The inline directive fix in Bluetooth which was breaking the build

7) Fix crashes in the ATP CLIP code due to ARP cleanups this merge

8) JME driver doesn't flush RX FIFO correctly, from Guo-Fu Tseng.
9) Some ip6_route_output() callers test the return value for NULL, but
this never happens as the convention is to return a dst entry with
dst->error set. Fixes from RonQing Li.
10) Logitech Harmony 900 should be handled by zaurus driver not
cdc_ether, update white lists and black lists accordingly. From
Scott Talbert.
11) Receiving from certain kinds of devices there won't be a MAC header,
so there is no MAC header to fixup in the IPSEC code, and if we try
to do it we'll crash. Fix from Eric Dumazet.
12) Port type array indexing off-by-one in mlx4 driver, fix from Yevgeny
Petrilin.
13) Fix regression in link-down handling in davinci_emac which causes
all RX descriptors to be freed up and therefore RX to wedge
completely, from Christian Riesch.
14) It took two attempts, but ctnetlink soft lockups seem to be
cured now, from Pablo Neira Ayuso.
15) Endianness bug fix in ENIC driver, from Santosh Nayak.
16) The long ago conversion of the PPP fragmentation code over to
abstracted SKB list handling wasn't perfect, once we get an
out of sequence SKB we don't flush the rest of them like we
should. From Ben McKeegan.
17) Fix regression of ->ip_summed initialization in sfc driver.
From Ben Hutchings.
18) Bluetooth timeout mistakenly using msecs instead of jiffies,
from Andrzej Kaczmarek.
19) Using _sync variant of work cancellation results in deadlocks,
use the non _sync variants instead. From Andre Guedes.
20) Bluetooth rfcomm code had reference counting problems leading
to crashes, fix from Octavian Purdila.
21) The conversion of netem over to classful qdisc handling added
two bugs to netem_dequeue(), fixes from Eric Dumazet.
22) Missing pci_iounmap() in ATM Solos driver. Fix from Julia Lawall.
23) b44_pci_exit() should not have __exit tag since it's invoked from
non-__exit code. From Nikola Pajkovsky.
24) The conversion of the neighbour hash tables over to RCU added a
race, fixed here by adding the necessary reread of tbl->nht, fix
from Michel Machado.
25) When we added VF (virtual function) attributes for network device
dumps, this potentially bloats up the size of the dump of one
network device such that the dump size is too large for the buffer
allocated by properly written netlink applications.
In particular, if you add 255 VFs to a network device, parts of
GLIBC stop working.
To fix this, we add an attribute that is used to turn on these
extended portions of the network device dump. Sophisticaed
applications like 'ip' that want to see this stuff will be changed
to set the attribute, whereas things like GLIBC that don't care
about VFs simply will not, and therefore won't be busted by the
mere presence of VFs on a network device.
Thanks to the tireless work of Greg Rose on this fix.

When pre-allocating skbs for received packets, we set ip_summed =
CHECKSUM_UNNCESSARY. We used to change it back to CHECKSUM_NONE when
the received packet had an incorrect checksum or unhandled protocol.
Commit bc8acf2c8c3e43fcc192762a9f964b3e9a17748b ('drivers/net: avoid
some skb->ip_summed initializations') mistakenly replaced the latter
assignment with a DEBUG-only assertion that ip_summed ==
CHECKSUM_NONE. This assertion is always false, but it seems no-one
has exercised this code path in a DEBUG build.
Fix this by moving our assignment of CHECKSUM_UNNECESSARY into
efx_rx_packet_gro().

This patch fixes a (mostly cosmetic) bug introduced by the patch
'ppp: Use SKB queue abstraction interfaces in fragment processing'
found here: http://www.spinics.net/lists/netdev/msg153312.html
The above patch rewrote and moved the code responsible for cleaning
up discarded fragments but the new code does not catch every case
where this is necessary. This results in some discarded fragments
remaining in the queue, and triggering a 'bad seq' error on the
subsequent call to ppp_mp_reconstruct. Fragments are discarded
whenever other fragments of the same frame have been lost.
This can generate a lot of unwanted and misleading log messages.
This patch also adds additional detail to the debug logging to
make it clearer which fragments were lost and which other fragments
were discarded as a result of losses. (Run pppd with 'kdebug 1'
option to enable debug logging.)

Adapt omap-iommu-debug to the latest omap-iommu API changes, which
were introduced by commit fabdbca "iommu/omap: eliminate the public
omap_find_iommu_device() method".
In a nutshell, iommu users are not expected to provide the omap_iommu
handle anymore - instead, iommus are attached using their user's device
handle.
omap-iommu-debug is a hybrid beast though: it invokes both public and
private omap iommu API, so fix it as necessary (otherwise a crash
is imminent).
Note: omap-iommu-debug is a bit disturbing, as it fiddles with internal
omap iommu data and requires exposing API which is otherwise not needed.
It should better be more tightly coupled with omap-iommu, to prevent
further bit rot and avoid exposing redundant API. Naturally that's out
of scope for the -rc cycle, so for now just fix the obvious.

This patch fixes a regression that was introduced by
commit 0a5f38467765ee15478db90d81e40c269c8dda20
davinci_emac: Add Carrier Link OK check in Davinci RX Handler
Said commit adds a check whether the carrier link is ok. If the link is
not ok, the skb is freed and no new dma descriptor added to the rx dma
channel. This causes trouble during initialization when the carrier
status has not yet been updated. If a lot of packets are received while
netif_carrier_ok returns false, all dma descriptors are freed and the
rx dma transfer is stopped.
The bug occurs when the board is connected to a network with lots of
traffic and the ifconfig down/up is done, e.g., when reconfiguring
the interface with DHCP.
The bug can be reproduced by flood pinging the davinci board while doing
ifconfig eth0 down
ifconfig eth0 up
on the board.
After that, the rx path stops working and the overrun value reported
by ifconfig is counting up.
This patch reverts commit 0a5f38467765ee15478db90d81e40c269c8dda20
and instead issues warnings only if cpdma_chan_submit returns -ENOMEM.

This patch adds the PHY_HAS_INTERRUPT flag for IC+101 device series.
Also the patch does a simple dity-up to signal that
the driver actually is for IP101A LF and IP101G devices.
In fact, these are two similar PHYs that have the same IDs
and mainly differ for the EEE capability supported in the
G series.

The code for ip1001_config_init() was totally broken if you were not
using RGMII. Instead of returning an error code or zero it actually
returned the value in the IP1001_SPEC_CTRL_STATUS_2 register. It was
also trying to set the IP1001_APS_ON bit , but never actually wrote
back the register.
The error checking was also incorrect in both this function and the
reset function, so this patch fixes that up in a consistent fashion.

By hwmon sysfs interface convention, setting pwm_enable to zero sets a fan
to full speed. In the f75375s driver, this need be done by enabling
manual fan control, plus duty mode for the F875387 chip, and then setting
the maximum duty cycle. Fix a bug where the two necessary register writes
were swapped, effectively discarding the setting to full-speed.

In the current kernel implementation, the Logitech Harmony 900 remote
control is matched to the cdc_ether driver through the generic
USB_CDC_SUBCLASS_MDLM entry. However, this device appears to be of the
pseudo-MDLM (Belcarra) type, rather than the standard one. This patch
blacklists the Harmony 900 from the cdc_ether driver and whitelists it for
the pseudo-MDLM driver in zaurus.

Intel, radeon, exynos fixes.
Intel: fixes a few Ivybridge hangs, along with fixing RC6 on SNB (still
not on, but at least allows for distros to patch it on easily).
radeon: oops reading some files in debugfs that weren't meant to appear,
a fix that touches a lot of files, so looks worse than it is, it fixes
an oops if a GPU reset fails and userspace keeps submitting more data,
along with a minor BIOS fix for newer boards.
exynos: a group of fixes for exynos, they've sent me a few more but
these were all I got through, and its no hw vanilla kernel users see a
lot off yet.

This patch fixes an unbalanced refcount issue.
Elevating the lock for both kref_put and also for controller node deletion.
Previously, controller deletion was protected but the not the kref_put. This
was causing the other thread to pick up the controller structure which was
already kref'd zero.
This was causing the following WARN_ON and also sometimes panic.
