Current IPv6 implementation uses inetpeer to store metrics for routes. The problem of inetpeer is that it doesn't take subnet prefix length in to consideration. If two routes have the same address but different prefix length, they share same inetpeer. So changing metrics of one route also affects the other. The fix is to allocate separate metrics storage for each route. Signed-off-by: Zheng Yan <zheng.z.yan@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This patch fixes a bug in the iscsit_fe_sendpage_sg() transmit codepath that was originally introduced with the v3.1 iscsi-target merge that incorrectly uses hardcoded cmd->iov_data_count values to determine cmd->iov_data[] offsets for extra outgoing padding and DataDigest payload vectors. This code is obviously incorrect for the DataDigest enabled case with sendpage offload, and this fix ensures correct operation for padding + DataDigest, padding only, and DataDigest only cases. The bug was introduced during a pre-merge change in iscsit_fe_sendpage_sg() to natively use struct scatterlist instead of the legacy v3.0 struct se_mem logic.

Attempt to reduce the number of IP packets emitted in response to single SCTP packet (2e3216cd) introduced a complication - if a packet contains two COOKIE_ECHO chunks and nothing else then SCTP state machine corks the socket while processing first COOKIE_ECHO and then loses the association and forgets to uncork the socket. To deal with the issue add new SCTP command which can be used to set association explictly. Use this new command when processing second COOKIE_ECHO chunk to restore the context for SCTP state machine. Signed-off-by: Max Matveev <makc@redhat.com> Signed-off-by: David S.

This patch makes iscsi-target explictly disable OFMarker=Yes and IFMarker=yes parameter key usage during iscsi login by setting IFMarkInt_Reject and OFMarkInt_Reject values in iscsi_enforce_integrity_rules() to effectively disable iscsi marker usage. With this patch, an initiator proposer asking to enable either marker parameter keys will be issued a 'No' response, and the target sets OFMarkInt + IFMarkInt parameter key response to 'Irrelevant'. With markers disabled during iscsi login, this patch removes the problematic on-stack local-scope array for marker intervals in iscsit_do_rx_data() + iscsit_do_tx_data(), and other related marker code in iscsi_target_util.c. This fixes a potentional stack smashing scenario with small range markers enabled and a large MRDSL as reported by DanC here: [bug report] target: stack can be smashed http://www.spinics.net/lists/target-devel/msg00453.htmlReported-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

This patch adds target_parse_naa_6h_vendor_specific() to address a bug where the conversion of PRODUCT SERIAL NUMBER to use hex2bin() in target_emulate_evpd_83() was not doing proper isxdigit() checking. This conversion of the vpd_unit_serial configifs attribute is done while generating a VPD=0x83 NAA IEEE Registered Extended DESIGNATOR format's 100 bits of unique VENDOR SPECIFIC IDENTIFIER + VENDOR SPECIFIC IDENTIFIER EXTENSION area. This patch allows vpd_unit_serial (VPD=0x80) and the T10 Vendor ID DESIGNATOR format (VPD=0x83) to continue to use free-form variable length ASCII values, and now skips any non hex characters for fixed length NAA IEEE Registered Extended DESIGNATOR format (VPD=0x83) requring the binary conversion. This was originally reported by Martin after the v3.1-rc1 change to use hex2bin() in commit 11650b85 where the use of non hex characters in vpd_unit_serial generated different values than the original v3.0 internal hex -> binary code. This v3.1 change caused a problem with filesystems who write a NAA DESIGNATOR onto it's ondisk metadata, and this patch will (again) change existing values to ensure that non hex characters are not included in the fixed length NAA DESIGNATOR. Note this patch still expects vpd_unit_serial to be set via existing userspace methods of uuid generation, and does not do strict formatting via configfs input. The original bug report and thread can be found here: NAA breakage http://www.spinics.net/lists/target-devel/msg00477.html The v3.1-rc1 formatting of VPD=0x83 w/o this patch: VPD INQUIRY: Device Identification page Designation descriptor number 1, descriptor length: 20 designator_type: NAA, code_set: Binary associated with the addressed logical unit NAA 6, IEEE Company_id: 0x1405 Vendor Specific Identifier: 0xffde35ebf Vendor Specific Identifier Extension: 0x3092f498ffa820f9 [0x6001405ffde35ebf3092f498ffa820f9] Designation descriptor number 2, descriptor length: 56 designator_type: T10 vendor identification, code_set: ASCII associated with the addressed logical unit vendor id: LIO-ORG vendor specific: IBLOCK:ffde35ec-3092-4980-a820-917636ca54f1 The v3.1-final formatting of VPD=0x83 w/ this patch: VPD INQUIRY: Device Identification page Designation descriptor number 1, descriptor length: 20 designator_type: NAA, code_set: Binary associated with the addressed logical unit NAA 6, IEEE Company_id: 0x1405 Vendor Specific Identifier: 0xffde35ec3 Vendor Specific Identifier Extension: 0x924980a82091763 [0x6001405ffde35ec30924980a82091763] Designation descriptor number 2, descriptor length: 56 designator_type: T10 vendor identification, code_set: ASCII associated with the addressed logical unit vendor id: LIO-ORG vendor specific: IBLOCK:ffde35ec-3092-4980-a820-917636ca54f1 (v2: Fix parsing code to dereference + check for string terminator instead of null pointer to ensure a zeroed payload for vpd_unit_serial less than 100 bits of NAA DESIGNATOR VENDOR SPECIFIC area.

Problem: Changed from wake_up_interruptible -> wake_up_process and wait_event_interruptible-> schedule_timeout_interruptible broke the FCoE target. Earlier approach of wake_up_interruptible was also looking at 'queue_cnt' which is not necessary, because it increment of 'queue_cnt' with wake_up_inetrriptible / waker_up_process introduces race condition. Fix: Instead of fixing the code which used wake_up_process and remove 'queue_cnt', using work_queue based approach is cleaner and acheives same result. As well, work queue based approach has less programming overhead and OS manages threads which processes work queues. This patch is developed by Christoph Hellwig and reviwed+validated by Kiran Patil.

Problem: HW DDP context wasn;t invalidated in case of ABORTS, etc... This leads to the problem where memory pages which are used for DDP as user descriptor could get reused for some other purpose (such as to satisfy new memory allocation request either by kernel or user mode threads) and since HW DDP context was not invalidated, HW continue to write to those pages, hence causing memory corruption. Fix: Either on incoming ABORTS or due to exchange time out, allowed the target to cleanup HW DDP context if it was setup for respective ft_cmd. Added new function to perform this cleanup, furthur it can be enhanced for other cleanup activity. Additinal Notes: To avoid calling ddp_done from multiple places, composed the functionality in helper function "ft_invl_hw_context" and it is being called from multiple places. Cleaned up code in function "ft_recv_write_data" w.r.t DDP. Signed-off-by: Kiran Patil <kiran.patil@intel.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

When work is scheduled with schedule_work(), the work can end up running on multiple CPUs at the same time -- this happens if the work is already running on one CPU and schedule_work() is called on another CPU. This leads to list corruption with target_qf_do_work(), which is roughly doing: spin_lock(...); list_for_each_entry_safe(...) { list_del(...); spin_unlock(...); // do stuff spin_lock(...); } With multiple CPUs running this code, one CPU can end up deleting the list entry that the other CPU is about to work on. Fix this by splicing the list entries onto a local list and then operating on that in the work function. This way, each invocation of target_qf_do_work() operates on its own local list and so multiple invocations don't corrupt each other's list. This also avoids dropping and reacquiring the lock for each list entry. Signed-off-by: Roland Dreier <roland@purestorage.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

On x86-64, they were just wasteful: with the explicitly added (now unnecessary) padding, the size of the alternatives structure was 16 bytes, and an alignment of 8 bytes didn't hurt much. However, it was still silly, since the natural size and alignment for the structure is actually just 12 bytes, 4-byte aligned since commit 59e97e4d ("x86: Make alternative instruction pointers relative"). So removing the padding, and removing the extra alignment is just a good idea. On x86-32, the alignment of 4 bytes was correct, but was incorrectly hardcoded as 8 bytes in <asm/alternative-asm.h>. That header file had used to be an x86-64 only header file, but various unification efforts have made it be used for x86-32 too (ie the unification of rwlock and rwsem). That in turn caused x86-32 boot failures, because the extra alignment would result in random zero-filled words in the altinstructions section, causing oopses early at boot when doing alternative instruction replacement. So just remove all the alignment noise entirely. It's wrong, and it's unnecessary. The section itself is already properly aligned by the linker scripts, and all additions to the section had better be of the proper 12-byte format, keeping it aligned. So if the align directive were to ever make a difference, that would be an indication of a serious bug to begin with.
