Pull SCSI target fixes from Nicholas Bellinger: "This target series for v4.10 contains fixes which address a few long-standing bugs that DATERA's QA + automation teams have uncovered while putting v4.1.y target code into production usage. We've been running the top three in our nightly automated regression runs for the last two months, and the COMPARE_AND_WRITE fix Mr. Gary Guo has been manually verifying against a four node ESX cluster this past week. Note all of them have CC' stable tags. Summary: - Fix a bug with ESX EXTENDED_COPY + SAM_STAT_RESERVATION_CONFLICT status, where target_core_xcopy.c logic was incorrectly returning SAM_STAT_CHECK_CONDITION for all non SAM_STAT_GOOD cases (Nixon Vincent) - Fix a TMR LUN_RESET hung task bug while other in-flight TMRs are being aborted, before the new one had been dispatched into tmr_wq (Rob Millner) - Fix a long standing double free OOPs, where a dynamically generated 'demo-mode' NodeACL has multiple sessions associated with it, and the /sys/kernel/config/target/$FABRIC/$WWN/ subsequently disables demo-mode, but never converts the dynamic ACL into a explicit ACL (Rob Millner) - Fix a long standing reference leak with ESX VAAI COMPARE_AND_WRITE when the second phase WRITE COMMIT command fails, resulting in CHECK_CONDITION response never being sent and se_cmd->cmd_kref never reaching zero (Gary Guo) Beyond these items on v4.1.y we've reproduced, fixed, and run through our regression test suite using iscsi-target exports, there are two additional outstanding list items: - Remove a >= v4.2 RCU conversion BUG_ON that would trigger when dynamic node NodeACLs where being converted to explicit NodeACLs. The patch drops the BUG_ON to follow how pre RCU conversion worked for this special case (Benjamin Estrabaud) - Add ibmvscsis target_core_fabric_ops->max_data_sg_nent assignment to match what IBM's Virtual SCSI hypervisor is already enforcing at transport layer.

cpumask: use nr_cpumask_bits for parsing functions

2017-02-08T23:41:43Z

Commit 513e3d2d11c9 ("cpumask: always use nr_cpu_ids in formatting and parsing functions") converted both cpumask printing and parsing functions to use nr_cpu_ids instead of nr_cpumask_bits. While this was okay for the printing functions as it just picked one of the two output formats that we were alternating between depending on a kernel config, doing the same for parsing wasn't okay. nr_cpumask_bits can be either nr_cpu_ids or NR_CPUS. We can always use nr_cpu_ids but that is a variable while NR_CPUS is a constant, so it can be more efficient to use NR_CPUS when we can get away with it. Converting the printing functions to nr_cpu_ids makes sense because it affects how the masks get presented to userspace and doesn't break anything; however, using nr_cpu_ids for parsing functions can incorrectly leave the higher bits uninitialized while reading in these masks from userland. As all testing and comparison functions use nr_cpumask_bits which can be larger than nr_cpu_ids, the parsed cpumasks can erroneously yield false negative results. This made the taskstats interface incorrectly return -EINVAL even when the inputs were correct. Fix it by restoring the parse functions to use nr_cpumask_bits instead of nr_cpu_ids.

mm: avoid returning VM_FAULT_RETRY from ->page_mkwrite handlers

2017-02-08T23:41:43Z

Some ->page_mkwrite handlers may return VM_FAULT_RETRY as its return code (GFS2 or Lustre can definitely do this). However VM_FAULT_RETRY from ->page_mkwrite is completely unhandled by the mm code and results in locking and writeably mapping the page which definitely is not what the caller wanted. Fix Lustre and block_page_mkwrite_ret() used by other filesystems (notably GFS2) to return VM_FAULT_NOPAGE instead which results in bailing out from the fault code, the CPU then retries the access, and we fault again effectively doing what the handler wanted.

net: introduce device min_header_len

2017-02-08T18:56:37Z

The stack must not pass packets to device drivers that are shorter than the minimum link layer header length. Previously, packet sockets would drop packets smaller than or equal to dev->hard_header_len, but this has false positives. Zero length payload is used over Ethernet. Other link layer protocols support variable length headers. Support for validation of these protocols removed the min length check for all protocols. Introduce an explicit dev->min_header_len parameter and drop all packets below this value. Initially, set it to non-zero only for Ethernet and loopback. Other protocols can follow in a patch to net-next.

lwtunnel: valid encap attr check should return 0 when lwtunnel is disabled

target: Fix multi-session dynamic se_node_acl double free OOPs

2017-02-08T16:25:23Z

This patch addresses a long-standing bug with multi-session (eg: iscsi-target + iser-target) se_node_acl dynamic free withini transport_deregister_session(). This bug is caused when a storage endpoint is configured with demo-mode (generate_node_acls = 1 + cache_dynamic_acls = 1) initiators, and initiator login creates a new dynamic node acl and attaches two sessions to it. After that, demo-mode for the storage instance is disabled via configfs (generate_node_acls = 0 + cache_dynamic_acls = 0) and the existing dynamic acl is never converted to an explicit ACL. The end result is dynamic acl resources are released twice when the sessions are shutdown in transport_deregister_session(). If the storage instance is not changed to disable demo-mode, or the dynamic acl is converted to an explict ACL, or there is only a single session associated with the dynamic ACL, the bug is not triggered. To address this big, move the release of dynamic se_node_acl memory into target_complete_nacl() so it's only freed once when se_node_acl->acl_kref reaches zero.
