2016-07-22ovl: verify upper dentry in ovl_remove_and_whiteout()Maxim Patlasov1-30/+24
The upper dentry may become stale before we call ovl_lock_rename_workdir. For example, someone could (mistakenly or maliciously) manually unlink(2) it directly from upperdir. To ensure it is not stale, let's lookup it after ovl_lock_rename_workdir and and check if it matches the upper dentry. Essentially, it is the same problem and similar solution as in commit 11f3710417d0 ("ovl: verify upper dentry before unlink and rename").

2016-07-21ASoC: samsung: Specify DMA channels through struct snd_dmaengine_pcm_configSylwester Nawrocki8-21/+39
The DMA channel names are specified through struct snd_dmaengine_pcm_config rather than using SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag when booting with devicetree in order to properly support deferred probing. Without this change the sound machine driver initialization can complete successfully with unavailable DMA resources.

The TDM mode using PCM format now has two-bit right shift due to the format configuration in the driver. According to Figure 4-13 in the CS53L30 datasheet, using ASP_SCLK_INV = 0 and SHIFT_LEFT = 1 should be the correct combination to create one-bit right shift for the DSP type A format.

2016-07-21tty/vt/keyboard: fix OOB access in do_compute_shiftstate()Dmitry Torokhov1-21/+9
The size of individual keymap in drivers/tty/vt/keyboard.c is NR_KEYS, which is currently 256, whereas number of keys/buttons in input device (and therefor in key_down) is much larger - KEY_CNT - 768, and that can cause out-of-bound access when we do sym = U(key_maps[0][k]); with large 'k'. To fix it we should not attempt iterating beyond smaller of NR_KEYS and KEY_CNT. Also while at it let's switch to for_each_set_bit() instead of open-coding it.

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>
2016-07-20net/mlx4_en: Add resilience in low memory systemsEugenia Emantayev3-37/+132
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 Williams2-8/+9
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.

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.

2016-07-17net: cavium: liquidio: Avoid dma_unmap_single on uninitialized ndataFlorian Fainelli1-4/+5
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.

2016-07-17vlan: use a valid default mtu value for vlan over macsecPaolo Abeni3-6/+18
macsec can't cope with mtu frames which need vlan tag insertion, and vlan device set the default mtu equal to the underlying dev's one. By default vlan over macsec devices use invalid mtu, dropping all the large packets. This patch adds a netif helper to check if an upper vlan device needs mtu reduction. The helper is used during vlan devices initialization to set a valid default and during mtu updating to forbid invalid, too bit, mtu values. The helper currently only check if the lower dev is a macsec device, if we get more users, we need to update only the helper (possibly reserving an additional IFF bit).
