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").

2016-07-20Input: tsc200x - report proper input_dev nameMichael Welling4-6/+25
Passes input_id struct to the common probe function for the tsc200x drivers instead of just the bustype. This allows for the use of the product variable to set the input_dev->name variable according to the type of touchscreen used. Note that when we introduced support for TSC2004 we started calling everything TSC200X, so let's keep this quirk.

2016-07-20tty/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.

2016-07-19packet: fix second argument of sock_tx_timestamp()Yoshihiro Shimoda1-3/+3
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.

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 <[email protected]>
2016-07-19net/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.

2016-07-18net/sched/sch_htb: clamp xstats tokens to fit into 32-bit intKonstantin Khlebnikov1-2/+4
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.

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.

2016-07-16vlan: 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).

2016-07-15mlxsw: spectrum: Prevent invalid ingress buffer mappingIdo Schimmel3-3/+19
Packets entering the switch are mapped to a Switch Priority (SP) according to their PCP value (untagged frames are mapped to SP 0). The packets are classified to a priority group (PG) buffer in the port's headroom according to their SP. The switch maintains another mapping (SP to IEEE priority), which is used to generate PFC frames for lossless PGs. This mapping is initialized to IEEE = SP % 8. Therefore, when mapping SP 'x' to PG 'y' we create a situation in which an IEEE priority is mapped to two different PGs: IEEE 'x' ---> SP 'x' ---> PG 'y' IEEE 'x' ---> SP 'x + 8' ---> PG '0' (default) Which is invalid, as a flow can use only one PG buffer. Fix this by mapping both SP 'x' and 'x + 8' to the same PG buffer.

Without this check, the following XFS_I invocations would return bad pointers when used on non-XFS inodes (perhaps pointers into preceding allocator chunks). This could be used by an attacker to trick xfs_swap_extents into performing locking operations on attacker-chosen structures in kernel memory, potentially leading to code execution in the kernel. (I have not investigated how likely this is to be usable for an attack in practice.)

Kiran fixes a bug which was found when we abruptly remove a cable which caused a panic. Set the VSI broadcast promiscuous mode during VSI add sequence and prevents adding MAC filter if specified MAC address is broadcast. Paolo Abeni fixes a bug by returning the actual work done, capped to weight - 1, since the core doesn't allow to return the full budget when the driver modifies the NAPI status. Guilherme Piccoli fixes an issue where the q_vector initialization routine sets the affinity _mask of a q_vector based on v_idx value. This means a loop iterates on v_idx, which is an incremental value, and the cpumask is created based on this value. This is a problem in systems with multiple logical CPUs per core (like in SMT scenarios).

2016-07-15tcp: enable per-socket rate limiting of all 'challenge acks'Jason Baron1-17/+22
The per-socket rate limit for 'challenge acks' was introduced in the context of limiting ack loops: commit f2b2c582e824 ("tcp: mitigate ACK loops for connections as tcp_sock") And I think it can be extended to rate limit all 'challenge acks' on a per-socket basis. Since we have the global tcp_challenge_ack_limit, this patch allows for tcp_challenge_ack_limit to be set to a large value and effectively rely on the per-socket limit, or set tcp_challenge_ack_limit to a lower value and still prevents a single connections from consuming the entire challenge ack quota. It further moves in the direction of eliminating the global limit at some point, as Eric Dumazet has suggested.

2016-07-16media: fix airspy usb probe error pathJames Patrick-Evans1-2/+1
Fix a memory leak on probe error of the airspy usb device driver. The problem is triggered when more than 64 usb devices register with v4l2 of type VFL_TYPE_SDR or VFL_TYPE_SUBDEV. The memory leak is caused by the probe function of the airspy driver mishandeling errors and not freeing the corresponding control structures when an error occours registering the device to v4l2 core. A badusb device can emulate 64 of these devices, and then through continual emulated connect/disconnect of the 65th device, cause the kernel to run out of RAM and crash the kernel, thus causing a local DOS vulnerability.
