This patch resolves false errors from MSGDMA in TX mSGDMA MM to ST mode, and is a continuation of the patch recently submitted by Andrea Oetken. The MSGDMA had a logic bug that masked detection of this issue prior to Quartus 14.1/Build 164. When the MSGDMA logic bug was addressed in Quartus 14.1/Build 164, the driver problem was exposed. The problem is corrected by making sure MSGDMA_DESC_CTL_TR_ERR_IRQ is not set for any of the transmit DMA descriptors, and only used for receive descriptors. Fixes: 71cd26e7 altera tse: Error-Bit on tx-avalon-stream always set. Signed-off-by:

The recent commit to only register the EHEA memory hotplug hooks on adapter probe has a few problems. Firstly the reference counting is wrong for multiple adapters, in that the hooks are registered multiple times. Secondly the check in the tear down path is backward. Finally the error path doesn't decrement the count. The multiple registration of the hooks is the biggest problem, as it leads to oopses when the system is rebooted, and/or errors during memory hotplug, eg: $ ./mem-on-off-test.sh -r 2 ... ehea: memory is going offline ehea: LPAR memory changed - re-initializing driver ehea: re-initializing driver complete ehea: memory is going offline ehea: LPAR memory changed - re-initializing driver ehea: opcode=26c ret=fffffffffffffffc arg1=8000000003000003 arg2=0 arg3=700000060000d600 arg4=3fded0000 arg5=200 arg6=0 arg7=0 ehea: register_rpage_mr failed ehea: registering mr failed ehea: register MR failed - driver inoperable! ehea: memory is going offline Fixes: aa183323 ("ehea: Register memory hotplug, reboot and crash hooks on adapter probe") Signed-off-by:

When having permanent EEH error, the PCI device will be removed from the system. For this case, we shouldn't set pcierr_recovery to true wrongly, which blocks the driver to release the allocated interrupts and their handlers. Eventually, we can't disable MSI or MSIx successfully because of the MSI or MSIx interrupts still have associated interrupt actions, which is turned into following stack dump.

[ 3897.923145] BUG: unable to handle kernel NULL pointer dereference at 0000000000000080 [ 3897.931025] IP: [<ffffffffa9f27686>] reqsk_timer_handler+0x1a6/0x243 There is a race when reqsk_timer_handler() and tcp_check_req() call inet_csk_reqsk_queue_unlink() on the same req at the same time. Before commit fa76ce73 ("inet: get rid of central tcp/dccp listener timer"), listener spinlock was held and race could not happen. To solve this bug, we change reqsk_queue_unlink() to not assume req must be found, and we return a status, to conditionally release a refcount on the request sock. This also means tcp_check_req() in non fastopen case might or not consume req refcount, so tcp_v6_hnd_req() & tcp_v4_hnd_req() have to properly handle this. (Same remark for dccp_check_req() and its callers) inet_csk_reqsk_queue_drop() is now too big to be inlined, as it is called 4 times in tcp and 3 times in dccp.

The conversion of mac80211's station table to rhashtable had a bug that I found by accident in code review, that hadn't been found as rhashtable apparently managed to have a maximum hash chain length of one (!) in all our testing. In order to test the bug and verify the fix I set my rhashtable's max_size very low (4) in order to force getting hash collisions. At that point, rhashtable WARNed in rhashtable_insert_rehash() but didn't actually reject the hash table insertion. This caused it to lose insertions - my master list of stations would have 9 entries, but the rhashtable only had 5. This may warrant a deeper look, but that WARN_ON() just shouldn't happen. Fix this by not returning true from rht_grow_above_100() when the rhashtable's max_size has been reached - in this case the user is explicitly configuring it to be at most that big, so even if it's now above 100% it shouldn't attempt to resize. This fixes the "lost insertion" issue and consequently allows my code to display its error (and verify my fix for it.) Signed-off-by:

Presence of an unbound loop in tcp_send_fin() had always been hard to explain when analyzing crash dumps involving gigantic dying processes with millions of sockets. Lets try a different strategy : In case of memory pressure, try to add the FIN flag to last packet in write queue, even if packet was already sent. TCP stack will be able to deliver this FIN after a timeout event. Note that this FIN being delivered by a retransmit, it also carries a Push flag given our current implementation. By checking sk_under_memory_pressure(), we anticipate that cooking many FIN packets might deplete tcp memory. In the case we could not allocate a packet, even with __GFP_WAIT allocation, then not sending a FIN seems quite reasonable if it allows to get rid of this socket, free memory, and not block the process from eventually doing other useful work.

When link statistics is dumped over netlink, we iterate over the list of peer nodes and append each links statistics to the netlink msg. In the case where the dump is resumed after filling up a nlmsg, the node refcnt is decremented without having been incremented previously which may cause the node reference to be freed. When this happens, the following info/stacktrace will be generated, followed by a crash or undefined behavior. We fix this by removing the erroneous call to tipc_node_put inside the loop that iterates over nodes. [ 384.312303] INFO: trying to register non-static key.

In the function tipc_sk_rcv(), the stack variable 'err' is only initialized to TIPC_ERR_NO_PORT for the first iteration over the link input queue. If a chain of messages are received from a link, failure to lookup the socket for any but the first message will cause the message to bounce back out on a random link. We fix this by properly initializing err. Signed-off-by:

When a new topology server is launched in a new namespace, its listening socket is inserted into the "init ns" namespace's socket hash table rather than the one owned by the new namespace. Although the socket's namespace is forcedly changed to the new namespace later, the socket is still stored in the socket hash table of "init ns" namespace. When a client created in the new namespace connects its own topology server, the connection is failed as its server's socket could not be found from its own namespace's socket table. If __sock_create() instead of original sock_create_kern() is used to create the server's socket through specifying an expected namesapce, the socket will be inserted into the specified namespace's socket table, thereby avoiding to the topology server broken issue.

AFAIK the PAPR document which defines the virtual device interface used by the ibmveth driver doesn't specify a specific maximum MTU. So, in the ibmveth driver, the maximum allowed MTU is determined by the maximum allocated buffer size of 64k (corresponding to one page in the common case) minus the per-buffer overhead IBMVETH_BUFF_OH (which has value 22 for 14 bytes of ethernet header, plus 8 bytes for an opaque handle). This suggests a maximum allowable MTU of 65514 bytes, but in fact the driver only permits a maximum MTU of 65513. This is because there is a < instead of an <= in ibmveth_change_mtu(), which only permits an MTU which is strictly smaller than the buffer size, rather than allowing the buffer to be completely filled. This patch fixes the buglet. Signed-off-by:

build_skb() should look at the page pfmemalloc status. If set, this means page allocator allocated this page in the expectation it would help to free other pages. Networking stack can do that only if skb->pfmemalloc is also set. Also, we must refrain using high order pages from the pfmemalloc reserve, so __page_frag_refill() must also use __GFP_NOMEMALLOC for them. Under memory pressure, using order-0 pages is probably the best strategy. Signed-off-by:

An MPLS network is a single trust domain where the edges must be in control of what labels make their way into the core. The simplest way of ensuring this is for the edge device to always impose the labels, and not allow forward labeled traffic from untrusted neighbours. This is achieved by allowing a per-device configuration of whether MPLS traffic input from that interface should be processed or not. To be secure by default, the default state is changed to MPLS being disabled on all interfaces unless explicitly enabled and no global option is provided to change the default. Whilst this differs from other protocols (e.g. IPv6), network operators are used to explicitly enabling MPLS forwarding on interfaces, and with the number of links to the MPLS core typically fairly low this doesn't present too much of a burden on operators.

When rhashtable_insert_rehash() fails with ENOMEM, this indicates that we can't allocate the necessary memory in the current context but the limits as set by the user would still allow to grow. Thus attempt an async resize in the background where we can allocate using GFP_KERNEL which is more likely to succeed. The insertion itself will still fail to indicate pressure.

The contents here is: - a large branch of cleanups of the CM/PRM blocks on OMAP. - a couple of patches plumbing up CM/PRM on OMAP5 and DRA7. - a branch with DT updates for Freescale i.MX. including some shuffling from .dts to .dtsi (include) files that causes a little churn" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (78 commits) ARM: OMAP2+: Fix booting with configs that don't have MFD_SYSCON ARM: OMAP4+: control: add support for initializing control module via DT ARM: dts: dra7: add minimal l4 bus layout with control module support ARM: dts: omap5: add minimal l4 bus layout with control module support ARM: OMAP4+: control: remove support for legacy pad read/write ARM: OMAP4: display: convert display to use syscon for dsi muxing ARM: dts: omap4: add minimal l4 bus layout with control module support ARM: dts: am4372: add minimal l4 bus layout with control module support ARM: dts: am43xx-epos-evm: fix pinmux node layout ARM: dts: am33xx: add minimal l4 bus layout with control module support ARM: dts: omap3: add minimal l4 bus layout with control module support ARM: dts: omap24xx: add minimal l4 bus layout with control module support ARM: OMAP2+: control: add syscon support for register accesses ARM: OMAP2+: id: cache omap_type value ARM: OMAP2+: control: remove API for getting control module base address ARM: OMAP2+: clock: add low-level support for regmap ARM: OMAP4+: PRM: get rid of cpu_is_omap44xx calls from interrupt init ARM: OMAP4+: PRM: setup prm_features from the PRM init time flags ARM: OMAP2+: CM: move SoC specific init calls within a generic API ARM: OMAP4+: PRM: determine prm_device_inst based on DT compatibility ... -

Pull ARM SoC defconfig updates from Olof Johansson: "We keep collecting defconfig updates in a separate branch mostly to encourage people to handle them separately and avoid conflicts between different topics. Most of these are enablement of new drivers that have come in, or minor config refreshes due to reorderings in Kconfig files, etc. I.e. mostly minor churn of various kinds. We might start folding this branch into something else for upstream merge since it's so small, but keep it independent in our own tree for the above reasons" * tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (38 commits) ARM: multi_v7_defconfig: enable alpine platform ARM: multi_v7_defconfig: Add gpio-restart driver ARM: multi_v7_defconfig: Build the Marvell WiFi-Ex driver as a module ARM: multi_v7_defconfig: Enable support for ELAN i2c trackpads ARM: multi_v7_defconfig: Enable Tegra ACTMON support ARM: configs: remove all CONFIG_RCAR_AUDMAC_PP from ARM defconfigs ARM: configs: enable Marvell Armada 39x in multi_v7_defconfig ARM: exynos_defconfig: Enable HDMI support ARM: exynos_defconfig: Enable options to mount a rootfs via NFS ARM: qcom: Increase MMC_BLOCK_MINORS in defconfig ARM: mvebu: Enable perf support in mvebu_v7_defconfig ARM: exynos_defconfig: Enable ChromeOS EC chardev driver ARM: exynos_defconfig: Enable CPU idle ARM: exynos_defconfig: Enable Marvell WiFi-Ex support arm: qcom: Update defconfig arm: qcom: Enable lpass clock driver in defconfig ARM: omap2plus_defconfig: Enable n900 modem as loadable modules ARM: omap2plus_defconfig: Update bluetooth options ARM: omap2plus_defconfig: Enable leds-pwm ARM: omap1_defconfig: drop obsolete Kconfig symbols ...

Pull ARM SoC multiplatform code changes from Olof Johansson: "The changes here belong to two main platforms: - Atmel At91 is flipping the bit and going multiplatform. This includes some cleanups and removal of code, and the final flip of config dependencies - Shmobile has several platforms that are going multiplatform, but this branch also contains a bunch of cleanups that they weren't able to keep separate in a good way.

Pull ARM SoC driver updates from Olof Johansson: "Driver updates for v4.1. Some of these are for drivers/soc, where we find more and more SoC-specific drivers these days. Some are for other driver subsystems where we have received acks from the appropriate maintainers. The larger parts of this branch are: - MediaTek support for their PMIC wrapper interface, a high-level interface for talking to the system PMIC over a dedicated I2C interface. - Qualcomm SCM driver has been moved to drivers/firmware.

Pull ARM DT updates from Olof Johansson: "As always, this tends to be one of our bigger branches. There are lots of updates this release, but not that many jumps out as something that needs more detailed coverage. Some of the highlights are: - DTs for the new Annapurna Labs Alpine platform - more graphics DT pieces falling into place on Exynos, bridges, clocks. - plenty of DT updates for Qualcomm platforms for various IP blocks - some churn on Tegra due to switch-over to tool-generated pinctrl data - misc fixes and updates for Atmel at91 platforms - various DT updates to add IP block support on Broadcom's Cygnus platforms - more updates for Renesas platforms as DT support is added for various IP blocks (IPMMU, display, audio, etc)" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (231 commits) ARM: dts: alpine: add internal pci Revert "ARM: dts: mt8135: Add pinctrl/GPIO/EINT node for mt8135."
