[ Upstream commit 33c6b1f6 ] netlink dump operations take module as parameter to hold reference for entire netlink dump duration. Currently it holds ref only on genl module which is not correct when we use ops registered to genl from another module. Following patch adds module pointer to genl_ops so that netlink can hold ref count on it. Signed-off-by:

[ Upstream commit 9b96309c ] In case of genl-family with parallel ops off, dumpif() callback is expected to run under genl_lock, But commit def31174 (genl: Allow concurrent genl callbacks.) changed this behaviour where only first dumpit() op was called under genl-lock. For subsequent dump, only nlk->cb_lock was taken. Following patch fixes it by defining locked dumpit() and done() callback which takes care of genl-locking. Signed-off-by:

[ Upstream commit 77a482bd ] Fix ipgre_header() (header_ops->create) to return the correct amount of bytes pushed. Most callers of dev_hard_header() seem to care only if it was success, but af_packet.c uses it as offset to the skb to copy from userspace only once.

[ Upstream commit 3e3be275 ] In case a subtree did not match we currently stop backtracking and return NULL (root table from fib_lookup). This could yield in invalid routing table lookups when using subtrees. Instead continue to backtrack until a valid subtree or node is found and return this match. Also remove unneeded NULL check.

[ Upstream commit cd6b423a ] While investigating about strange increase of retransmit rates on hosts ~24 days after boot, Van found hystart was disabled if ca->epoch_start was 0, as following condition is true when tcp_time_stamp high order bit is set. (s32)(tcp_time_stamp - ca->epoch_start) < HZ Quoting Van : At initialization & after every loss ca->epoch_start is set to zero so I believe that the above line will turn off hystart as soon as the 2^31 bit is set in tcp_time_stamp & hystart will stay off for 24 days. I think we've observed that cubic's restart is too aggressive without hystart so this might account for the higher drop rate we observe. Diagnosed-by:

[ Upstream commit 2ed0edf9 ] commit 17a6e9f1 ("tcp_cubic: fix clock dependency") added an overflow error in bictcp_update() in following code : /* change the unit from HZ to bictcp_HZ */ t = ((tcp_time_stamp + msecs_to_jiffies(ca->delay_min>>3) - ca->epoch_start) << BICTCP_HZ) / HZ; Because msecs_to_jiffies() being unsigned long, compiler does implicit type promotion. We really want to constrain (tcp_time_stamp - ca->epoch_start) to a signed 32bit value, or else 't' has unexpected high values. This bugs triggers an increase of retransmit rates ~24 days after boot [1], as the high order bit of tcp_time_stamp flips. [1] for hosts with HZ=1000 Big thanks to Van Jacobson for spotting this problem. Diagnosed-by:

[ Upstream commit 5f671d6b ] It's possible to assign an invalid value to the net.core.somaxconn sysctl variable, because there is no checks at all. The sk_max_ack_backlog field of the sock structure is defined as unsigned short. Therefore, the backlog argument in inet_listen() shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall is truncated to the somaxconn value. So, the somaxconn value shouldn't exceed 65535 (USHRT_MAX). Also, negative values of somaxconn are meaningless. before: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 net.core.somaxconn = 65536 $ sysctl -w net.core.somaxconn=-100 net.core.somaxconn = -100 after: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 error: "Invalid argument" setting key "net.core.somaxconn" $ sysctl -w net.core.somaxconn=-100 error: "Invalid argument" setting key "net.core.somaxconn" Based on a prior patch from Changli Gao.

commit 4e67fb5f upstream. Avoid overlapping register regions by making the initial blklen of a new node 1. If a register write occurs to a yet uncached register, that is lower than but near an existing node's base_reg, a new node is created and it's blklen is set to an arbitrary value (sizeof(*rbnode)). That may cause this node to overlap with another node. Those nodes should be merged, but this merge doesn't happen yet, so this patch at least makes the initial blklen small enough to avoid hitting the wrong node, which may otherwise lead to severe breakage.

commit 28aaa950 upstream. This patch addresses a potential NULL pointer dereference regression in iscsit_setup_nop_out() code, specifically for two cases when a solicited NOPOUT triggers a ISCSI_REASON_PROTOCOL_ERROR reject to be generated. This is because iscsi_cmd is expected to be NULL for solicited NOPOUT case before iscsit_process_nop_out() locates the descriptor via TTT using iscsit_find_cmd_from_ttt().

commit c9a03c12 upstream. This patch fixes a bug in __iscsi_target_login_thread() where an explicit network portal thread reset ends up leaking the iscsit_transport module reference, along with the associated iscsi_conn allocation. This manifests itself with iser-target where a NP reset causes the extra iscsit_transport reference to be taken in iscsit_conn_set_transport() during the reset, which prevents the ib_isert module from being unloaded after the NP thread shutdown has finished.

commit 9d86a2be upstream. This patch addresses a regression bug within ImmediateData=Yes failure handling that ends up triggering an OOPs within >= v3.10 iscsi-target code. The problem occurs when iscsit_process_scsi_cmd() does the call to target_put_sess_cmd(), and once again in iscsit_get_immediate_data() that is triggered during two different cases: - When iscsit_sequence_cmd() returns CMDSN_LOWER_THAN_EXP, for which the descriptor state will already have been set to ISTATE_REMOVE by iscsit_sequence_cmd(), and - When iscsi_cmd->sense_reason is set, for which iscsit_execute_cmd() will have already called transport_send_check_condition_and_sense() to queue the exception response. It changes iscsit_process_scsi_cmd() to drop the early call, and makes iscsit_get_immediate_data() call target_put_sess_cmd() from a single location after dumping the immediate data for the failed command. The regression was initially introduced in commit: commit 561bf158 Author: Nicholas Bellinger <nab@linux-iscsi.org> Date: Wed Jul 3 03:58:58 2013 -0700 iscsi-target: Fix iscsit_sequence_cmd reject handling for iser Signed-off-by:

commit d2e9fc14 upstream. ath9k_htc adds padding between the 802.11 header and the payload during TX by moving the header. When handing the frame back to mac80211 for TX status handling the header is not moved back into its original position. This can result in a too small skb headroom when entering ath9k_htc again (due to a soft retransmission for example) causing an skb_under_panic oops. Fix this by moving the 802.11 header back into its original position before returning the frame to mac80211 as other drivers like rt2x00 or ath5k do. Reported-by:

commit 347e2233 upstream. Some architectures, such as ARM-32 do not return the same base address when you call kmap_atomic() twice on the same page. This causes problems for the memmove() call in the XDR helper routine "_shift_data_right_pages()", since it defeats the detection of overlapping memory ranges, and has been seen to corrupt memory. The fix is to distinguish between the case where we're doing an inter-page copy or not. In the former case of we know that the memory ranges cannot possibly overlap, so we can additionally micro-optimise by replacing memmove() with memcpy(). Reported-by:

commit b22ce278 upstream. If !PREEMPT, a kworker running work items back to back can hog CPU. This becomes dangerous when a self-requeueing work item which is waiting for something to happen races against stop_machine. Such self-requeueing work item would requeue itself indefinitely hogging the kworker and CPU it's running on while stop_machine would wait for that CPU to enter stop_machine while preventing anything else from happening on all other CPUs. The two would deadlock. Jamie Liu reports that this deadlock scenario exists around scsi_requeue_run_queue() and libata port multiplier support, where one port may exclude command processing from other ports. With the right timing, scsi_requeue_run_queue() can end up requeueing itself trying to execute an IO which is asked to be retried while another device has an exclusive access, which in turn can't make forward progress due to stop_machine. Fix it by invoking cond_resched() after executing each work item. Signed-off-by:

commit 6f6b8951 upstream. If the system had a few memory groups and all of them were destroyed, memcg_limited_groups_array_size has non-zero value, but all new caches are created without memcg_params, because memcg_kmem_enabled() returns false. We try to enumirate child caches in a few places and all of them are potentially dangerous. For example my kernel is compiled with CONFIG_SLAB and it crashed when I tryed to mount a NFS share after a few experiments with kmemcg.
