* net/mlx5e: Introduce RX Page-ReuseTariq Toukan2017-06-224-37/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a Page-Reuse mechanism in non-Striding RQ RX datapath. A WQE (RX descriptor) buffer is a page, that in most cases was fully wasted on a packet that is much smaller, requiring a new page for the next round. In this patch, we implement a page-reuse mechanism, that resembles a `SW Striding RQ`. We allow the WQE to reuse its allocated page as much as it could, until the page is fully consumed. In each round, the WQE is capable of receiving packet of maximal size (MTU). Yet, upon the reception of a packet, the WQE knows the actual packet size, and consumes the exact amount of memory needed to build a linear SKB. Then, it updates the buffer pointer within the page accordingly, for the next round. Feature is mutually exclusive with XDP (packet-per-page) and LRO (session size is a power of two, needs unused page). Performance tests: iperf tcp tests show huge gain: -------------------------------------------- num streams | BW before | BW after | ratio | 1 | 22.2 | 30.9 | 1.39x | 8 | 64.2 | 93.6 | 1.46x | 64 | 56.7 | 91.4 | 1.61x | -------------------------------------------- Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
* net/mlx5e: Enhance RX SKB headroom logicTariq Toukan2017-06-222-8/+7Star
| | | | | | | | | | | | | | In the RX memory scheme of non Striding RQ, we use linear SKBs. Keeping NET_IP_ALIGN in headroom can improve performance on some archs. In addition, take this headroom into account when calculating the LRO WQE size. These are not needed in Striding RQ as they're done implicitly within the non-linear SKB allocation.

* net/mlx5e: Build SKB with exact frag_sizeTariq Toukan2017-06-223-6/+6
| | | | | | | | | | | | Build the SKB over the receive packet instead of the whole page. Getting the SKB's linear data and shared_info closer improves locality. In addition, this opens up the possibility to make use of other parts of the page in the downstream page-reuse patch.

For this some data structure needs to be reserved which is tied to the interface, which is done by brcmf_fws_add_interface(). However, it checks the mode. Replace that by checking result from brcmf_fws_queue_skbs(). Otherwise the driver will crash in a null pointer dereference when data is transmitted on the interface.

In such circumstancies if you do a suspend/resume cycle the kernel hangs on resume due a NULL pointer dereference in resume function. So in brcmf_sdio_firmware_callback() we need to unbind the driver from both sdio_func devices when firmware load failure is indicated.

LLD skips notifying uP as the rdma queues were not created by then (will leave it to ULD to notify the uP). As the ULD comes up, it also skips notifying the uP as the flag FULL_INIT_DONE is not set yet (ULD assumes that the interface is not up yet). Consequently, this race between uld and lld leaves uP unnotified about where to send the ctrl queue completions to, leading to iwarp RI_RES WR failure. Here is the race: CPU 0 CPU1 - allocates nic rx queus - t4_sge_alloc_ctrl_txq() (if rdma rsp queues exists, tell uP to route ctrl queue compl to rdma rspq) - acquires the mutex_lock - allocates rdma response queues - if FULL_INIT_DONE set, tell uP to route ctrl queue compl to rdma rspq - relinquishes mutex_lock - acquires the mutex_lock - enable_rx() - set FULL_INIT_DONE - relinquishes mutex_lock This patch fixes the above issue.

Robert reported that then applications may (randomly) fault if the struct iwreq they pass happens to land within 8 bytes of the end of a mapping (the struct is only 32 bytes, vs. struct ifreq's 40 bytes). To fix this, pull out the code handling wireless extension ioctls and copy only the smaller structure in this case. This bug goes back a long time, I tracked that it was introduced into mainline in 2.1.15, over 20 years ago!

This makes the whole routing code very buggy. In dn_dst_check_expire(), dnrt_free() is called when rt expires. This makes the routes inserted by dn_route_output_slow() not able to be freed as the refcnt is not released. In dn_dst_gc(), dnrt_drop() is called to release rt which could potentially cause the dst->__refcnt to be dropped to -1. In dn_run_flush(), dst_free() is called to release all the dst. Again, it makes the dst inserted by dn_route_output_slow() not able to be released and also, it does not wait on the rcu and could potentially cause crash in the path where other users still refer to this dst. This patch makes sure both input and output path do not take dst->__refcnt before calling dn_insert_route() and also makes sure dnrt_free()/dst_free() is called when removing dst from the hash table. The only difference between those 2 calls is that dnrt_free() waits on the rcu while dst_free() does not.

This could lead to the size-remaining variable wrapping and the data pointer going over the end of the buffer. Fix this by making the various variable-length data checks use the padded length.

The problem is there's one gap in [1], during which if the pending dad work is removed elsewhere. It will miss to hold ifa, but the dad word is still idea and queue. if (!delayed_work_pending(&ifp->dad_work)) in6_ifa_hold(ifp); <--------------[1] mod_delayed_work(addrconf_wq, &ifp->dad_work, delay); An use-after-free issue can be caused by this. Chen Wei found this issue when WARN_ON(!hlist_unhashed(&ifp->addr_lst)) in net6_ifa_finish_destroy was hit because of it. As Hannes' suggestion, this patch is to fix it by holding ifa first in addrconf_mod_dad_work, then calling mod_delayed_work and putting ifa if the dad_work is already in queue. Note that this patch did not choose to fix it with: if (!mod_delayed_work(delay)) in6_ifa_hold(ifp); As with it, when delay == 0, dad_work would be scheduled immediately, all addrconf_mod_dad_work(0) callings had to be moved under ifp->lock.

Kevin Vandeventer reported, that his new AMD Ryzen locks up hard on boot when the AMD pinctrl driver is initialized. The reason is an interrupt storm. It's not clear whether that's caused by hardware or firmware or both. Using chained interrupts on X86 is a dangerous endavour. If a system is misconfigured or the hardware buggy there is no safety net to catch an interrupt storm. Convert the driver to use a regular interrupt for the demultiplex handler. This allows the interrupt storm detector to catch the malfunction and lets the system boot up. This should be backported to stable because it's likely that more users run into this problem as the AMD Ryzen machines are spreading.
