Subject: [PATCH 1/2] ip6_output: fragment outgoing reassembled skb properly
If reassembled packet would fit into outdev MTU, it is not fragmented
according the original frag size and it is send as single big packet.
The second case is if skb is gso. In that case fragmentation does not happen
according to the original frag size.
This patch fixes these.

From 5c0df04613dd39fba5d2a43eaf90a2dc1dcd8899 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/2] netfilter: push reasm skb through instead of original
frag skbs
Pushing original fragments through causes several problems. For example
for matching, frags may not be matched correctly. Take following
example:
<example>
On HOSTA do:
ip6tables -I INPUT -p icmpv6 -j DROP
ip6tables -I INPUT -p icmpv6 -m icmp6 --icmpv6-type 128 -j ACCEPT
and on HOSTB you do:
ping6 HOSTA -s2000 (MTU is 1500)
Incoming echo requests will be filtered out on HOSTA. This issue does
not occur with smaller packets than MTU (where fragmentation does not happen)
</example>
As was discussed previously, the only correct solution seems to be to use
reassembled skb instead of separete frags. Doing this has positive side
effects in reducing sk_buff by one pointer (nfct_reasm) and also the reams
dances in ipvs and conntrack can be removed.
Future plan is to remove net/ipv6/netfilter/nf_conntrack_reasm.c
entirely and use code in net/ipv6/reassembly.c instead.

From 92eb77d0ffbaa71b501a0a8dabf09a351bf4267f Mon Sep 17 00:00:00 2001

Subject: Input: evdev - fall back to vmalloc for client event buffer
evdev always tries to allocate the event buffer for clients using
kzalloc rather than vmalloc, presumably to avoid mapping overhead where
possible. However, drivers like bcm5974, which claims support for
reporting 16 fingers simultaneously, can have an extraordinarily large
buffer. The resultant contiguous order-4 allocation attempt fails due
to fragmentation, and the device is thus unusable until reboot.
Try kzalloc if we can to avoid the mapping overhead, but if that fails,
fall back to vzalloc.

Bugzilla: 967652
Upstream-status: 3.13 (should hit stable)
From daf727225b8abfdfe424716abac3d15a3ac5626a Mon Sep 17 00:00:00 2001

Date: Thu, 31 Oct 2013 23:05:24 +0100
Subject: [PATCH] KVM: x86: fix emulation of "movzbl %bpl, %eax"
When I was looking at RHEL5.9's failure to start with
unrestricted_guest=0/emulate_invalid_guest_state=1, I got it working with a
slightly older tree than kvm.git. I now debugged the remaining failure,
which was introduced by commit 660696d1 (KVM: X86 emulator: fix
source operand decoding for 8bit mov[zs]x instructions, 2013-04-24)
introduced a similar mis-emulation to the one in commit 8acb4207 (KVM:
fix sil/dil/bpl/spl in the mod/rm fields, 2013-05-30). The incorrect
decoding occurs in 8-bit movzx/movsx instructions whose 8-bit operand
is sil/dil/bpl/spl.
Needless to say, "movzbl %bpl, %eax" does occur in RHEL5.9's decompression
prolog, just a handful of instructions before finally giving control to
the decompressed vmlinux and getting out of the invalid guest state.
Because OpMem8 bypasses decode_modrm, the same handling of the REX prefix
must be applied to OpMem8.

+GPIO reset controller
+=====================
+
+A GPIO reset controller controls a single GPIO that is connected to the reset
+pin of a peripheral IC. Please also refer to reset.txt in this directory for
+common reset controller binding usage.
+
+Required properties:
+- compatible: Should be "gpio-reset"
+- reset-gpios: A gpio used as reset line. The gpio specifier for this property
+ depends on the gpio controller that provides the gpio.
+- #reset-cells: 0, see below
+
+Optional properties:
+- reset-delay-us: delay in microseconds. The gpio reset line will be asserted for
+ this duration to reset.
+- initially-in-reset: boolean. If not set, the initial state should be a
+ deasserted reset line. If this property exists, the
+ reset line should be kept in reset.
+
+example:
+
+sii902x_reset: gpio-reset {
+ compatible = "gpio-reset";
+ reset-gpios = <&gpio5 0 GPIO_ACTIVE_LOW>;
+ reset-delay-us = <10000>;
+ initially-in-reset;
+ #reset-cells = <0>;
+};
+
+/* Device with nRESET pin connected to GPIO5_0 */
+sii902x@39 {
+ /* ... */
+ resets = <&sii902x_reset>; /* active-low GPIO5_0, 10 ms delay */
+};

Subject: [PATCH 2/2] sound: soc: soc-dmaengine-pcm: Add support for new
DMAEngine request API
Formerly these resources were coming HWMOD on OMAP-like SoCs. With the
impending removal of HWMOD data, drivers are being converted to use the
"of-dma" method of requesting DMA channels which from DT and can be obtained
using the dma_request_slave_channel API. Add support to the soc-dmaengine-pcm
helpers so that we can fetch and open channels using this method.

Subject: [PATCH] pinctrl: pinctrl-single must be initialized early.
When using pinctrl-single to handle i2c initialization, it has
to be done early. Whether this is the best way to do so, is an
exercise left to the reader.

commit 7eacd03810960823393521063734fc8188446bca
Author: Neil Horman <nhorman@tuxdriver.com>
Date: Fri Sep 13 11:05:33 2013 -0400
bonding: Make alb learning packet interval configurable
running bonding in ALB mode requires that learning packets be sent periodically,
so that the switch knows where to send responding traffic. However, depending
on switch configuration, there may not be any need to send traffic at the
default rate of 3 packets per second, which represents little more than wasted
data. Allow the ALB learning packet interval to be made configurable via sysfs

Subject: [PATCH 1/2] drm/radeon/audio: correct ACR table
The values were taken from the HDMI spec, but they assumed
exact x/1.001 clocks. Since we round the clocks, we also need
to calculate different N and CTS values.
Note that the N for 25.2/1.001 MHz at 44.1 kHz audio is out of
spec. Hopefully this mode is rarely used and/or HDMI sinks
tolerate overly large values of N.

Subject: [PATCH 2/2] drm/radeon/audio: improve ACR calculation
In order to have any realistic chance of calculating proper
ACR values, we need to be able to calculate both N and CTS,
not just CTS. We still aim for the ideal N as specified in
the HDMI spec though.

This is caused by a race between md device initialization by multipathd and
shell script to switch the scheduler using sysfs.
- multipathd:
SyS_ioctl -> do_vfs_ioctl -> dm_ctl_ioctl -> ctl_ioctl -> table_load
-> dm_setup_md_queue -> blk_init_allocated_queue -> elevator_init
q->elevator = elevator_alloc(q, e); // not yet initialized
- sh -c 'echo deadline > /sys/$DEVPATH/queue/scheduler':
elevator_switch (in the call trace above)
struct elevator_queue *old = q->elevator;
q->elevator = elevator_alloc(q, new_e);
elevator_exit(old); // lockup! (*)
- multipathd: (cont.)
err = e->ops.elevator_init_fn(q); // init fails; q->elevator is modified
(*) When del_timer_sync() is called, lock_timer_base() will loop infinitely
while timer->base == NULL. In this case, as timer will never initialized,
it results in lockup.
This patch introduces acquisition of q->sysfs_lock around elevator_init()
into blk_init_allocated_queue(), to provide mutual exclusion between
initialization of the q->scheduler and switching of the scheduler.
This should fix this bugzilla:

Add locking of q->sysfs_lock into elevator_change() (an exported function)
to ensure it is held to protect q->elevator from elevator_init(), even if
elevator_change() is called from non-sysfs paths.
sysfs path (elv_iosched_store) uses __elevator_change(), non-locking
version, as the lock is already taken by elv_iosched_store().

fix-child-thread-introspection.patch
View File

@ -1,76 +0,0 @@
Allow threads other than the main thread to do introspection of files in
proc without relying on read permissions. proc_pid_follow_link() calls
proc_fd_access_allowed() which ultimately calls __ptrace_may_access().
Though this allows additional access to some proc files, we do not
believe that this has any unintended security implications. However it
probably needs to be looked at carefully.
The original problem was a thread of a process whose permissions were
111 couldn't open its own /proc/self/exe This was interfering with a
special purpose debugging tool. A simple reproducer is below.:
#include <pthread.h>
#include <unistd.h>
#include <stdio.h>
#include <errno.h>
#include <stdlib.h>
#include <sys/types.h>
#define BUFSIZE 2048
void *thread_main(void *arg){
char *str=(char*)arg;
char buf[BUFSIZE];
ssize_t len=readlink("/proc/self/exe", buf, BUFSIZE);
if(len==-1)
printf("/proc/self/exe in %s: %s\n", str,sys_errlist[errno]);
else
printf("/proc/self/exe in %s: OK\n", str);
return 0;

exit(1);

pthread_join(thread, NULL);

addr_len if the msg_name is written to. The recv_error and rxpmtu
functions relied on the recvmsg functions to set up addr_len before.
As this does not happen any more we have to pass addr_len to those
functions as well and set it to the size of the corresponding sockaddr
length.
This broke traceroute and such.

Bugzilla: 1035887

From bceaa90240b6019ed73b49965eac7d167610be69 Mon Sep 17 00:00:00 2001
From: Hannes Frederic Sowa <hannes@stressinduktion.org>

Subject: [PATCH] inet: prevent leakage of uninitialized memory to user in recv
syscalls
Only update *addr_len when we actually fill in sockaddr, otherwise we
can return uninitialized memory from the stack to the caller in the
recvfrom, recvmmsg and recvmsg syscalls. Drop the the (addr_len == NULL)
checks because we only get called with a valid addr_len pointer either
from sock_common_recvmsg or inet_recvmsg.
If a blocking read waits on a socket which is concurrently shut down we
now return zero and set msg_msgnamelen to 0.

Subject: iommu: Remove stack trace from broken irq remapping warning
The warning for the irq remapping broken check in intel_irq_remapping.c is
pretty pointless. We need the warning, but we know where its comming from, the
stack trace will always be the same, and it needlessly triggers things like
Abrt. This changes the warning to just print a text warning about BIOS being
broken, without the stack trace, then sets the appropriate taint bit. Since we
automatically disable irq remapping, theres no need to contiue making Abrt jump
at this problem

Bugzilla: 1030015 1030017
Upstream-status: 3.13
From aeb45260747b0a1bf4d374d5e65298cc254cb4f5 Mon Sep 17 00:00:00 2001
From: Hannes Frederic Sowa <hannes@stressinduktion.org>

Subject: [PATCH] ipv6: fix headroom calculation in udp6_ufo_fragment
Commit 1e2bd517c108816220f262d7954b697af03b5f9c ("udp6: Fix udp
fragmentation for tunnel traffic.") changed the calculation if
there is enough space to include a fragment header in the skb from a
skb->mac_header dervived one to skb_headroom. Because we already peeled
off the skb to transport_header this is wrong. Change this back to check
if we have enough room before the mac_header.
This fixes a panic Saran Neti reported. He used the tbf scheduler which
skb_gso_segments the skb. The offsets get negative and we panic in memcpy
because the skb was erroneously not expanded at the head.

From: Eric Dumazet <edumazet@google.com>
Steinar reported reallocations of skb->head with IPv6, leading to
a warning in skb_try_coalesce()
It turns out iwl3945 has several problems :
1) skb->truesize is underestimated.
We really consume PAGE_SIZE bytes for a fragment,
not the frame length.
2) 128 bytes of initial headroom is a bit low and forces reallocations.
3) We can avoid consuming a full page for small enough frames.

Subject: iwlwifi: dvm: don't override mac80211's queue setting
Since we set IEEE80211_HW_QUEUE_CONTROL, we can let
mac80211 do the queue assignement and don't need to
override its decisions.
While reassiging the same values is harmless of course,
it triggered a WARNING when iwlwifi and mac80211 came
to different conclusions. This happened when mac80211 set
IEEE80211_TX_CTL_SEND_AFTER_DTIM, but didn't route the
packet to the cab_queue because no stations were asleep.
iwlwifi should not override mac80211's decicions for
offchannel packets and packets to be sent after DTIM,
but it should override mac80211's decision for AMPDUs
since we have a special queue for them. So for AMPDU,
we still override info->hw_queue by the AMPDU queue.
This avoids:

Bugzilla: 1024002
Upstream-status: Should hit 3.13 and CC'd to 3.12 stable
From f78dea064c5f7de07de4912a6e5136dbc443d614 Mon Sep 17 00:00:00 2001

Subject: libata: implement ATA_HORKAGE_NO_NCQ_TRIM and apply it to Micro M500 SSDs
Certain drives cannot handle queued TRIM commands properly, even
though support is indicated in the IDENTIFY DEVICE buffer. This patch
allows for disabling the commands for the affected drives and apply it
to the Micron/Crucial M500 SSDs which exhibit incorrect protocol
behavior when issued queued TRIM commands, which could lead to silent
data corruption.
tj: Merged two unnecessarily split patches and made minor edits
including shortening horkage name.

Subject: [PATCH 3/5] KEYS: Add a system blacklist keyring
This adds an additional keyring that is used to store certificates that
are blacklisted. This keyring is searched first when loading signed modules
and if the module's certificate is found, it will refuse to load. This is
useful in cases where third party certificates are used for module signing.

Subject: [PATCH 4/5] MODSIGN: Import certificates from UEFI Secure Boot
Secure Boot stores a list of allowed certificates in the 'db' variable.
This imports those certificates into the system trusted keyring. This
allows for a third party signing certificate to be used in conjunction
with signed modules. By importing the public certificate into the 'db'
variable, a user can allow a module signed with that certificate to
load. The shim UEFI bootloader has a similar certificate list stored
in the 'MokListRT' variable. We import those as well.
In the opposite case, Secure Boot maintains a list of disallowed
certificates in the 'dbx' variable. We load those certificates into
the newly introduced system blacklist keyring and forbid any module
signed with those from loading.

Subject: [PATCH 5/5] MODSIGN: Support not importing certs from db
If a user tells shim to not use the certs/hashes in the UEFI db variable
for verification purposes, shim will set a UEFI variable called MokIgnoreDB.
Have the uefi import code look for this and not import things from the db
variable.

Upstream-status: 3.13 and 3.12.4
From 9cb9fb275f8794546dc31a79f2f02127fed5baf2 Mon Sep 17 00:00:00 2001

Subject: [PATCH] net: rework recvmsg handler msg_name and msg_namelen logic
[ Upstream commit f3d3342602f8bcbf37d7c46641cb9bca7618eb1c ]
This patch now always passes msg->msg_namelen as 0. recvmsg handlers must
set msg_namelen to the proper size <= sizeof(struct sockaddr_storage)
to return msg_name to the user.
This prevents numerous uninitialized memory leaks we had in the
recvmsg handlers and makes it harder for new code to accidentally leak
uninitialized memory.
Optimize for the case recvfrom is called with NULL as address. We don't
need to copy the address at all, so set it to NULL before invoking the
recvmsg handler. We can do so, because all the recvmsg handlers must
cope with the case a plain read() is called on them. read() also sets
msg_name to NULL.
Also document these changes in include/linux/net.h as suggested by David
Miller.
Changes since RFC:
Set msg->msg_name = NULL if user specified a NULL in msg_name but had a
non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't
affect sendto as it would bail out earlier while trying to copy-in the
address. It also more naturally reflects the logic by the callers of
verify_iovec.
With this change in place I could remove "
if (!uaddr || msg_sys->msg_namelen == 0)
msg->msg_name = NULL
".
This change does not alter the user visible error logic as we ignore
msg_namelen as long as msg_name is NULL.
Also remove two unnecessary curly brackets in ___sys_recvmsg and change
comments to netdev style.

Subject: [PATCH] netfilter: nf_conntrack: use RCU safe kfree for conntrack
extensions
Commit 68b80f11 (netfilter: nf_nat: fix RCU races) introduced
RCU protection for freeing extension data when reallocation
moves them to a new location. We need the same protection when
freeing them in nf_ct_ext_free() in order to prevent a
use-after-free by other threads referencing a NAT extension data
via bysource list.

Subject: [PATCH] ntp: Make periodic RTC update more reliable
The current code requires that the scheduled update of the RTC happens
in the closest tick to the half of the second. This seems to be
difficult to achieve reliably. The scheduled work may be missing the
target time by a tick or two and be constantly rescheduled every second.
Relax the limit to 10 ticks. As a typical RTC drifts in the 11-minute
update interval by several milliseconds, this shouldn't affect the
overall accuracy of the RTC much.

rt2800usb-slow-down-TX-status-polling.patch
View File

@ -1,53 +0,0 @@
Polling TX statuses too frequently has two negative effects. First is
randomly peek CPU usage, causing overall system functioning delays.
Second bad effect is that device is not able to fill TX statuses in
H/W register on some workloads and we get lot of timeouts like below:
ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2
ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2
ieee80211 phy4: rt2800usb_txdone: Warning - Got TX status for an empty queue 2, dropping
This not only cause flood of messages in dmesg, but also bad throughput,
since rate scaling algorithm can not work optimally.
In the future, we should probably make polling interval be adjusted
automatically, but for now just increase values, this make mentioned
problems gone.

Subject: [PATCH 02/14] PCI: Lock down BAR access when module security is

Any hardware that can potentially generate DMA has to be locked down from
userspace in order to avoid it being possible for an attacker to modify
kernel code, allowing them to circumvent disabled module loading or module
signing. Default to paranoid - in future we can potentially relax this for
sufficiently IOMMU-isolated devices.

IO port access would permit users to gain access to PCI configuration

it down by default.

Subject: [PATCH 04/14] ACPI: Limit access to custom_method
custom_method effectively allows arbitrary access to system memory, making
it possible for an attacker to circumvent restrictions on module loading.
Disable it if any such restrictions have been enabled.

Subject: [PATCH 05/14] asus-wmi: Restrict debugfs interface when module
loading is restricted
We have no way of validating what all of the Asus WMI methods do on a
given machine, and there's a risk that some will allow hardware state to
be manipulated in such a way that arbitrary code can be executed in the
kernel, circumventing module loading restrictions. Prevent that if any of
these features are enabled.

Subject: [PATCH 12/14] efi: Disable secure boot if shim is in insecure mode
A user can manually tell the shim boot loader to disable validation of
images it loads. When a user does this, it creates a UEFI variable called
MokSBState that does not have the runtime attribute set. Given that the
user explicitly disabled validation, we can honor that and not enable
secure boot mode if that variable is set.

Socket fuzzers like sfuzz will trigger this printk a lot, even though it's
ratelimited. It isn't particularly useful, so just remove it.

Bugzilla: 1031086
Upstream-status: 3.12
From cd8fa0170867ce6e6e2d7edba1dc1a0b87485854 Mon Sep 17 00:00:00 2001
From: Christoph Lameter <cl@linux.com>

Subject: [PATCH] slab_common: Do not check for duplicate slab names
SLUB can alias multiple slab kmem_create_requests to one slab cache to save
memory and increase the cache hotness. As a result the name of the slab can be
stale. Only check the name for duplicates if we are in debug mode where we do
not merge multiple caches.
This fixes the following problem reported by Jonathan Brassow:
The problem with kmem_cache* is this:
*) Assume CONFIG_SLUB is set
1) kmem_cache_create(name="foo-a")
- creates new kmem_cache structure
2) kmem_cache_create(name="foo-b")
- If identical cache characteristics, it will be merged with the previously
created cache associated with "foo-a". The cache's refcount will be
incremented and an alias will be created via sysfs_slab_alias().
3) kmem_cache_destroy(<ptr>)
- Attempting to destroy cache associated with "foo-a", but instead the
refcount is simply decremented. I don't even think the sysfs aliases are
ever removed...
4) kmem_cache_create(name="foo-a")
- This FAILS because kmem_cache_sanity_check colides with the existing
name ("foo-a") associated with the non-removed cache.
This is a problem for RAID (specifically dm-raid) because the name used
for the kmem_cache_create is ("raid%d-%p", level, mddev). If the cache
persists for long enough, the memory address of an old mddev will be
reused for a new mddev - causing an identical formulation of the cache
name. Even though kmem_cache_destory had long ago been used to delete
the old cache, the merging of caches has cause the name and cache of that
old instance to be preserved and causes a colision (and thus failure) in
kmem_cache_create(). I see this regularly in my testing.

Subject: [PATCH] usbnet: fix status interrupt urb handling
Since commit 7b0c5f21f348a66de495868b8df0284e8dfd6bbf
"sierra_net: keep status interrupt URB active", sierra_net triggers
status interrupt polling before the net_device is opened (in order to
properly receive the sync message response).
To be able to receive further interrupts, the interrupt urb needs to be
re-submitted, so this patch removes the bogus check for netif_running().

From: Julian Stecklina <jsteckli@os.info.tu-dresden.de>
Subject: [PATCH] vfio, iommu: Fixed interaction of VFIO_IOMMU_MAP_DMA with IOMMU address limits
The BUG_ON in drivers/iommu/intel-iommu.c:785 can be triggered from userspace via
VFIO by calling the VFIO_IOMMU_MAP_DMA ioctl on a vfio device with any address
beyond the addressing capabilities of the IOMMU. The problem is that the ioctl code
calls iommu_iova_to_phys before it calls iommu_map. iommu_map handles the case that
it gets addresses beyond the addressing capabilities of its IOMMU.
intel_iommu_iova_to_phys does not.
This patch fixes iommu_iova_to_phys to return NULL for addresses beyond what the
IOMMU can handle. This in turn causes the ioctl call to fail in iommu_map and
(correctly) return EFAULT to the user with a helpful warning message in the kernel
log.

Subject: [PATCH net 1/1] via-velocity: fix netif_receive_skb use in irq
disabled section.

2fdac010bdcf10a30711b6924612dfc40daf19b8 ("via-velocity.c: update napi
implementation") overlooked an irq disabling spinlock when the Rx part
of the NAPI poll handler was converted from netif_rx to netif_receive_skb.
NAPI Rx processing can be taken out of the locked section with a pair of
napi_{disable / enable} since it only races with the MTU change function.
An heavier rework of the NAPI locking would be able to perform NAPI Tx
before Rx where I simply removed one of velocity_tx_srv calls.
