* | net/mlx5e: Avoid accessing NULL pointer at ndo_select_queueRana Shahout2015-08-253-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>

| * | RDS: return EMSGSIZE for oversize requests before processing/queueingMukesh Kacker2015-08-251-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | RDS: make sure rds_send_drop_to properly takes the m_rs_locksantosh.shilimkar@oracle.com2015-08-251-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When TCP pacing was added back in linux-3.12, we chose to apply a fixed ratio of 200 % against current rate, to allow probing for optimal throughput even during slow start phase, where cwnd can be doubled every other gRTT. At Google, we found it was better applying a different ratio while in Congestion Avoidance phase. This ratio was set to 120 %. We've used the normal tcp_in_slow_start() helper for a while, then tuned the condition to select the conservative ratio as soon as cwnd >= ssthresh/2 : - After cwnd reduction, it is safer to ramp up more slowly, as we approach optimal cwnd. - Initial ramp up (ssthresh == INFINITY) still allows doubling cwnd every other RTT.

* | tcp: fix slow start after idle vs TSO/GSOEric Dumazet2015-08-254-8/+22
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | slow start after idle might reduce cwnd, but we perform this after first packet was cooked and sent. With TSO/GSO, it means that we might send a full TSO packet even if cwnd should have been reduced to IW10. Moving the SSAI check in skb_entail() makes sense, because we slightly reduce number of times this check is done, especially for large send() and TCP Small queue callbacks from softirq context. As Neal pointed out, we also need to perform the check if/when receive window opens.
