For devices that can register page list that is bigger than USHRT_MAX, we actually take the wrong value for sg_tablesize. E.g: for CX4 max_fast_reg_page_list_len is 65536 (bigger than USHRT_MAX) so we set sg_tablesize to 0 by mistake. Therefore, each IO that is bigger than 4k splitted to "< 4k" chunks that cause performance degredation. Remove wrong sg_tablesize assignment, and use the value that was set during address resolution handler with the needed casting. Cc: <stable@vger.kernel.org> # v4.5+ Signed-off-by:

Function rx_data(), which handles ingress CPL_RX_DATA messages, was always sending an RX_DATA_ACK with the goal of updating the credits. However, if the RDMA connection is moved out of FPDU mode abruptly, then it is possible for iw_cxgb4 to process queued RX_DATA CPLs after HW has aborted the connection. These CPLs should not trigger RX_DATA_ACKS. If they do, HW can see a READ after DELETE of the DB_LE hash entry for the tid and post a LE_DB HashTblMemCrcError. Signed-off-by:

Commit ad61a4c7 ("iw_cxgb4: don't block in destroy_qp awaiting the last deref") introduced a bug where the RDMA QP EQ queue memory (and QIDs) are possibly freed before the underlying connection has been fully shutdown. The result being a possible DMA read issued by HW after the queue memory has been unmapped and freed. This results in possible WR corruption in the worst case, system bus errors if an IOMMU is in use, and SGE "bad WR" errors reported in the very least. The fix is to defer unmap/free of queue memory and QID resources until the QP struct has been fully dereferenced. To do this, the c4iw_ucontext must also be kept around until the last QP that references it is fully freed. In addition, since the last QP deref can happen in an IRQ disabled context, we need a new workqueue thread to do the final unmap/free of the EQ queue memory.

With the addition of the IB/Core drain API, iw_cxgb4 supported drain by watching the CQs when the QP was out of RTS and signalling "drain complete" when the last CQE is polled. This, however, doesn't fully support the drain semantics. Namely, the drain logic is supposed to signal "drain complete" only when the application has _processed_ the last CQE, not just removed them from the CQ. Thus a small timing hole exists that can cause touch after free type bugs in applications using the drain API (nvmf, iSER, for example). So iw_cxgb4 needs a better solution. The iWARP Verbs spec mandates that "_at some point_ after the QP is moved to ERROR", the iWARP driver MUST synchronously fail post_send and post_recv calls. iw_cxgb4 was currently not allowing any posts once the QP is in ERROR. This was in part due to the fact that the HW queues for the QP in ERROR state are disabled at this point, so there wasn't much else to do but fail the post operation synchronously. This restriction is what drove the first drain implementation in iw_cxgb4 that has the above mentioned flaw. This patch changes iw_cxgb4 to allow post_send and post_recv WRs after the QP is moved to ERROR state for kernel mode users, thus still adhering to the Verbs spec for user mode users, but allowing flush WRs for kernel users. Since the HW queues are disabled, we just synthesize a CQE for this post, queue it to the SW CQ, and then call the CQ event handler. This enables proper drain operations for the various storage applications. Signed-off-by:

Several people report seeing warnings about inconsistent radix tree nodes followed by crashes in the workingset code, which all looked like use-after-free access from the shadow node shrinker. Dave Jones managed to reproduce the issue with a debug patch applied, which confirmed that the radix tree shrinking indeed frees shadow nodes while they are still linked to the shadow LRU: WARNING: CPU: 2 PID: 53 at lib/radix-tree.c:643 delete_node+0x1e4/0x200 CPU: 2 PID: 53 Comm: kswapd0 Not tainted 4.10.0-rc2-think+ #3 Call Trace: delete_node+0x1e4/0x200 __radix_tree_delete_node+0xd/0x10 shadow_lru_isolate+0xe6/0x220 __list_lru_walk_one.isra.4+0x9b/0x190 list_lru_walk_one+0x23/0x30 scan_shadow_nodes+0x2e/0x40 shrink_slab.part.44+0x23d/0x5d0 shrink_node+0x22c/0x330 kswapd+0x392/0x8f0 This is the WARN_ON_ONCE(!list_empty(&node->private_list)) placed in the inlined radix_tree_shrink(). The problem is with 14b46879 ("mm: workingset: move shadow entry tracking to radix tree exceptional tracking"), which passes an update callback into the radix tree to link and unlink shadow leaf nodes when tree entries change, but forgot to pass the callback when reclaiming a shadow node. While the reclaimed shadow node itself is unlinked by the shrinker, its deletion from the tree can cause the left-most leaf node in the tree to be shrunk. If that happens to be a shadow node as well, we don't unlink it from the LRU as we should. Consider this tree, where the s are shadow entries: root->rnode | [0 n] | | [s ] [sssss] Now the shadow node shrinker reclaims the rightmost leaf node through the shadow node LRU: root->rnode | [0 ] | [s ] Because the parent of the deleted node is the first level below the root and has only one child in the left-most slot, the intermediate level is shrunk and the node containing the single shadow is put in its place: root->rnode | [s ] The shrinker again sees a single left-most slot in a first level node and thus decides to store the shadow in root->rnode directly and free the node - which is a leaf node on the shadow node LRU. root->rnode | s Without the update callback, the freed node remains on the shadow LRU, where it causes later shrinker runs to crash. Pass the node updater callback into __radix_tree_delete_node() in case the deletion causes the left-most branch in the tree to collapse too. Also add warnings when linked nodes are freed right away, rather than wait for the use-after-free when the list is scanned much later.

4.10-rc loadtest (even on x86, and even without THPCache) fails with "fork: Cannot allocate memory" or some such; and /proc/meminfo shows PageTables growing. Commit 953c66c2 ("mm: THP page cache support for ppc64") that got merged in rc1 removed the freeing of an unused preallocated pagetable after do_fault_around() has called map_pages(). This is usually a good optimization, so that the followup doesn't have to reallocate one; but it's not sufficient to shift the freeing into alloc_set_pte(), since there are failure cases (most commonly VM_FAULT_RETRY) which never reach finish_fault(). Check and free it at the outer level in do_fault(), then we don't need to worry in alloc_set_pte(), and can restore that to how it was (I cannot find any reason to pte_free() under lock as it was doing). And fix a separate pagetable leak, or crash, introduced by the same change, that could only show up on some ppc64: why does do_set_pmd()'s failure case attempt to withdraw a pagetable when it never deposited one, at the same time overwriting (so leaking) the vmf->prealloc_pte?
