2016-07-19packet: fix second argument of sock_tx_timestamp()Yoshihiro Shimoda
This patch fixes an issue that a syscall (e.g. sendto syscall) cannot work correctly. Since the sendto syscall doesn't have msg_control buffer, the sock_tx_timestamp() in packet_snd() cannot work correctly because the socks.tsflags is set to 0. So, this patch sets the socks.tsflags to sk->sk_tsflags as default.

2016-07-19Merge branch 'mlx4-fixes'David S. Miller
Tariq Toukan says: ==================== Safe flow for mlx4_en configuration change This patchset improves the mlx4_en driver resiliency, especially on systems with low memory. Upon a configuration change that requires the allocation of new resources, we first try to allocate, prior to destroying the current ones. Once it is successfully done, we release the old resources and attach the new ones. Otherwise, we stay with a functioning interface having the same old configuration. This improvement became of greater significance after removing the use of vmap. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2016-07-19net/mlx4_en: Add resilience in low memory systemsEugenia Emantayev
This patch fixes the lost of Ethernet port on low memory system, when driver frees its resources and fails to allocate new resources. Issue could happen while changing number of channels, rings size or changing the timestamp configuration. This fix is necessary because of removing vmap use in the code. When vmap was in use driver could allocate non-contiguous memory and make it contiguous with vmap. Now it could fail to allocate a large chunk of contiguous memory and lose the port. Current code tries to allocate new resources and then upon success frees the old resources.

2016-07-19nfit: make DIMM DSMs optionalDan Williams
Commit 4995734e973a "acpi, nfit: fix acpi_check_dsm() vs zero functions implemented" attempted to fix a QEMU regression by supporting its usage of a zero-mask as a valid response to a DSM-family probe request. However, this behavior breaks HP platforms that return a zero-mask by default causing the probe to misidentify the DSM-family. Instead, the QEMU regression can be fixed by simply not requiring the DSM family to be identified. This effectively reverts commit 4995734e973a, and removes the DSM requirement from the init path.

2016-07-18net/sched/sch_htb: clamp xstats tokens to fit into 32-bit intKonstantin Khlebnikov
In kernel HTB keeps tokens in signed 64-bit in nanoseconds. In netlink protocol these values are converted into pshed ticks (64ns for now) and truncated to 32-bit. In struct tc_htb_xstats fields "tokens" and "ctokens" are declared as unsigned 32-bit but they could be negative thus tool 'tc' prints them as signed. Big values loose higher bits and/or become negative. This patch clamps tokens in xstat into range from INT_MIN to INT_MAX. In this way it's easier to understand what's going on here.

2016-07-18perf probe: Warn unmatched function filter correctlyMasami Hiramatsu
Warn unmatched function filter correctly instead of warning "symbol-loading error", since that can be a filter issue. From the technical point of view, this adds a filter chech in map__load and if there is a filter, it returns -2 (filter-out), instead of -1 (error), and perf-probe checks it and change message. E.g. without this fix: # perf probe -F rt_sp* no symbols found in [kernel.kallsyms], maybe install a debug package? Failed to load symbols in kernel With this fix: # perf probe -F rt_sp* no symbols passed the given filter. Failed to find symbols matched to "rt_sp*" Error: Failed to show functions.

2016-07-18perf cpu_map: Add more helpersMark Rutland
In some cases it's necessry to figure out the map-local index of a given Linux logical CPU ID. Add a new helper, cpu_map__idx, to acquire this. As the logic is largely the same as the existing cpu_map__has, this is rewritten in terms of the new helper. At the same time, add the inverse operation, cpu_map__cpu, which yields the logical CPU id for a map-local index. While this can be performed manually, wrapping this in a helper can make code more legible.

2016-07-18perf stat: Balance opening and reading eventsMark Rutland
In create_perf_stat_counter, when a target CPU has not been provided, we call __perf_evsel__open with empty_cpu_map, and open a single FD per thread. However, in read_counter we assume that we opened events for the product of threads and CPUs described in the evsel's cpu_map. Thus, if an evsel has a cpu_map with more than one entry, we will attempt to access FDs that we didn't open. This could result in a number of problems (e.g. blocking while reading from STDIN if the fd memory happened to be initialised to zero). This is problematic for systems were a logical CPU PMU covers some arbitrary subset of CPUs. The cpu_map of any evsel for that PMU will be initialised based on the cpumask exposed through sysfs, even if the user requests per-thread events.

The i915 driver checks for color management properties changes as part of a plane update. Therefore a color management update must imply a plane update, otherwise we never update the transformation matrixes and degamma/gamma LUTs. v2: add comment about moving the commit of color management registers to an async worker v3: Commit color management register right after vblank v4: Move back color management commit condition together with planes commit v5: Trigger color management commit through the planes commit (Daniel) v6: Make plane change update more readable Fixes: 20a34e78f0d7 (drm/i915: Update color management during vblank evasion.)

2016-07-18drm/i915: Treat eDP as always connected, againVille Syrjälä
eDP should be treated as connected even if doesn't have an EDID. In that case we'll use the timings from the VBT. That used to be the case until commit f21a21983ef1 ("drm/i915: Splitting intel_dp_detect") broke things by considering even eDP disconnected if we fail to get an EDID for it. Fix things up again by treating eDP as always connected.

2016-07-18mmc: pxamci: fix potential oopsRobert Jarzmik
As reported by Dan in his report in [1], there is a potential NULL pointer derefence if these conditions are met : - there is no platform_data provided, ie. host->pdata = NULL Fix this by only using the platform data ro_invert when a gpio for read-only is provided by the platform data. This doesn't appear yet as every pxa board provides a platform_data, and calls pxa_set_mci_info() with a non NULL pointer. [1] [bug report] mmc: pxamci: fix card detect with slot-gpio API. The commit fd546ee6a7dc ("mmc: pxamci: fix card detect with slot-gpio API") from Sep 26, 2015, leads to the following static checker warning: drivers/mmc/host/pxamci.c:809 pxamci_probe() warn: variable dereferenced before check 'host->pdata' (see line 798) Fixes: fd546ee6a7dc ("mmc: pxamci: fix card detect with slot-gpio API") Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2016-07-18KEYS: Fix for erroneous trust of incorrectly signed X.509 certsMat Martineau
Arbitrary X.509 certificates without authority key identifiers (AKIs) can be added to "trusted" keyrings, including IMA or EVM certs loaded from the filesystem. Signature verification is currently bypassed for certs without AKIs. Trusted keys were recently refactored, and this bug is not present in 4.6. restrict_link_by_signature should return -ENOKEY (no matching parent certificate found) if the certificate being evaluated has no AKIs, instead of bypassing signature checks and returning 0 (new certificate accepted).

2016-07-16net: cavium: liquidio: Avoid dma_unmap_single on uninitialized ndataFlorian Fainelli
The label lio_xmit_failed is used 3 times through liquidio_xmit() but it always makes a call to dma_unmap_single() using potentially uninitialized variables from "ndata" variable. Out of the 3 gotos, 2 run after ndata has been initialized, and had a prior dma_map_single() call. Fix this by adding a new error label: lio_xmit_dma_failed which does this dma_unmap_single() and then processed with the lio_xmit_failed fallthrough.
