ACPICA commit 3f42ba76e2a0453976d3108296d5f656fdf2bd6e In this patch, FACS table mapping is also tuned a bit so that only the selected FACS table will be mapped by the OSPM (mapped on demand) and the FACS related global variables can be reduced.

2015-08-25ACPICA: Tables: Fix global table list issues by removing fixed table indexesLv Zheng
ACPICA commit c0b38b4c3982c2336ee92a2a14716107248bd941 The fixed table indexes leave holes in the global table list: 1. One hole can be seen when there is only 1 FACS provided by the BIOS. 2. Tow holes can be seen when it is a reduced hardware platform. The holes do not break OSPMs but have broken ACPI debugger "tables" command. Also the "fixed table indexes" mechanism may make the descriptors of the standard tables installed earlier than DSDT to be overwritten by the descriptors of the fixed tables. For example, FACP disappears from the global table list after DSDT is installed. This patch fixes all above issues by removing the "fixed table indexes" mechanism which is too complicated to be maintained in a regression safe manner. After removal, the table loader will determine the indexes of the fixed tables. Lv Zheng.

2015-08-25ppp: implement x-netns supportGuillaume Nault
Let packets move from one netns to the other at PPP encapsulation and decapsulation time. PPP units and channels remain in the netns in which they were originally created. Only the net_device may move to a different namespace. Cross netns handling is thus transparent to lower PPP layers (PPPoE, L2TP, etc.). PPP devices are automatically unregistered when their netns gets removed. So read() and poll() on the unit file descriptor will respectively receive EOF and POLLHUP. Channels aren't affected.

2015-08-25net/mlx5e: Avoid accessing NULL pointer at ndo_select_queueRana Shahout
To avoid multiply/division operations on the data path, we hold a {channel, tc}==>txq mapping table. We held this mapping table inside the channel object that is being destroyed upon some configuration operations (e.g MTU change). So in case ndo_select_queue occurs during such a configuration operation, it may access a NULL channel pointer, resulting in kernel panic. To fix this issue we moved the {channel, tc}==>txq mapping table outside the channel object so that it will be available also during such configuration operations.

2015-08-25mtip32x: fix regression introduced by blk-mq per-hctx flushJeff Moyer
Hi, After commit f70ced091707 (blk-mq: support per-distpatch_queue flush machinery), the mtip32xx driver may oops upon module load due to walking off the end of an array in mtip_init_cmd. On initialization of the flush_rq, init_request is called with request_index >= the maximum queue depth the driver supports. For mtip32xx, this value is used to index into an array. What this means is that the driver will walk off the end of the array, and either oops or cause random memory corruption. The problem is easily reproduced by doing modprobe/rmmod of the mtip32xx driver in a loop. I can typically reproduce the problem in about 30 seconds. Now, in the case of mtip32xx, it actually doesn't support flush/fua, so I think we can simply return without doing anything. In addition, no other mq-enabled driver does anything with the request_index passed into init_request(), so no other driver is affected. However, I'm not really sure what is expected of drivers. Ming, what did you envision drivers would do when initializing the flush requests? Signed-off-by: Jeff Moyer <jmoyer@redhat.com> Signed-off-by: Jens Axboe <axboe@fb.com>

Santosh Shilimkar says: ==================== RDS: Assorted bug fixes We would like to improve RDS upstream support and in that context, I started playing with it. But run into number of issues including as basic is RDS IB RDMA doesn't work. As part of the debug, I ended up creating the $subject series which has bunch of assorted fixes. At least with this series I can run RDS IB RDMA and other tests successfully. Some of these fixes have been done by Chris Meson, Andy Grover and Zach Brown while at Oracle. There are still more kinks with FMR and error handling and I plan to address them in a follow up series. Series generated against Linus's master(v4.2-rc-7) but also applies against next-next cleanly. Its tested on Oracle hardware with IB fabric for both bcopy as well as RDMA mode. I don't have access to iWARP hardware so any testing help on iWARP hardware appreciated. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2015-08-25RDS: return EMSGSIZE for oversize requests before processing/queueingMukesh Kacker
rds_send_queue_rm() allows for the "current datagram" being queued to exceed SO_SNDBUF thresholds by checking bytes queued without counting in length of current datagram. (Since sk_sndbuf is set to twice requested SO_SNDBUF value as a kernel heuristic this is usually fine!) If this "current datagram" squeezing past the threshold is itself many times the size of the sk_sndbuf threshold itself then even twice the SO_SNDBUF does not save us and it gets queued but cannot be transmitted. Threads block and deadlock and device becomes unusable. The check for this datagram not exceeding SNDBUF thresholds (EMSGSIZE) is not done on this datagram as that check is only done if queueing attempt fails. (Datagrams that follow this datagram fail queueing attempts, go through the check and eventually trip EMSGSIZE error but zero length datagrams silently fail!) This fix moves the check for datagrams exceeding SNDBUF limits before any processing or queueing is attempted and returns EMSGSIZE early in the rds_sndmsg() code. This change also ensures that all datagrams get checked for exceeding SNDBUF/sk_sndbuf size limits and the large datagrams that exceed those limits do not get to rds_send_queue_rm() code for processing.

2015-08-25RDS: make sure rds_send_drop_to properly takes the m_rs_locksantosh.shilimkar@oracle.com
rds_send_drop_to() is used during socket tear down to find all the messages on the socket and flush them . It can race with the acking code unless it takes the m_rs_lock on each and every message. This plugs a hole where we didn't take m_rs_lock on any message that didn't have the RDS_MSG_ON_CONN set. Taking m_rs_lock avoids double frees and other memory corruptions as the ack code trusts the message m_rs pointer on a socket that had actually been freed. We must take m_rs_lock to access m_rs. Because of lock nesting and rs access, we also need to acquire rs_lock.

Since RDS connction is persistent, we can end up sending the data even after large-send when the remote end is not active(for any reason).
