2016-09-01rps: flow_dissector: Fix uninitialized flow_keys used in __skb_get_hash possiblyGao Feng
The original codes depend on that the function parameters are evaluated from left to right. But the parameter's evaluation order is not defined in C standard actually. When flow_keys_have_l4(&keys) is invoked before ___skb_get_hash(skb, &keys, hashrnd) with some compilers or environment, the keys passed to flow_keys_have_l4 is not initialized.

2016-09-01kernel/fork: fix CLONE_CHILD_CLEARTID regression in nscdMichal Hocko
Commit fec1d0115240 ("[PATCH] Disable CLONE_CHILD_CLEARTID for abnormal exit") has caused a subtle regression in nscd which uses CLONE_CHILD_CLEARTID to clear the nscd_certainly_running flag in the shared databases, so that the clients are notified when nscd is restarted. Now, when nscd uses a non-persistent database, clients that have it mapped keep thinking the database is being updated by nscd, when in fact nscd has created a new (anonymous) one (for non-persistent databases it uses an unlinked file as backend). The original proposal for the CLONE_CHILD_CLEARTID change claimed (https://lkml.org/lkml/2006/10/25/233): : The NPTL library uses the CLONE_CHILD_CLEARTID flag on clone() syscalls : on behalf of pthread_create() library calls. This feature is used to : request that the kernel clear the thread-id in user space (at an address : provided in the syscall) when the thread disassociates itself from the : address space, which is done in mm_release(). : : Unfortunately, when a multi-threaded process incurs a core dump (such as : from a SIGSEGV), the core-dumping thread sends SIGKILL signals to all of : the other threads, which then proceed to clear their user-space tids : before synchronizing in exit_mm() with the start of core dumping. This : misrepresents the state of process's address space at the time of the : SIGSEGV and makes it more difficult for someone to debug NPTL and glibc : problems (misleading him/her to conclude that the threads had gone away : before the fault). : : The fix below is to simply avoid the CLONE_CHILD_CLEARTID action if a : core dump has been initiated. The resulting patch from Roland (https://lkml.org/lkml/2006/10/26/269) seems to have a larger scope than the original patch asked for. It seems that limitting the scope of the check to core dumping should work for SIGSEGV issue describe above.

2016-09-01printk/nmi: avoid direct printk()-s from __printk_nmi_flush()Sergey Senozhatsky
__printk_nmi_flush() can be called from nmi_panic(), therefore it has to test whether it's executed in NMI context and thus must route the messages through deferred printk() or via direct printk(). This is to avoid potential deadlocks, as described in commit cf9b1106c81c ("printk/nmi: flush NMI messages on the system panic"). However there remain two places where __printk_nmi_flush() does unconditional direct printk() calls: - pr_err("printk_nmi_flush: internal error ...") - pr_cont("\n") Factor out print_nmi_seq_line() parts into a new printk_nmi_flush_line() function, which takes care of in_nmi(), and use it in __printk_nmi_flush() for printing and error-reporting.

2016-09-01mm, vmscan: only allocate and reclaim from zones with pages managed by the ↵Mel Gorman
buddy allocator Firmware Assisted Dump (FA_DUMP) on ppc64 reserves substantial amounts of memory when booting a secondary kernel. Srikar Dronamraju reported that multiple nodes may have no memory managed by the buddy allocator but still return true for populated_zone(). Commit 1d82de618ddd ("mm, vmscan: make kswapd reclaim in terms of nodes") was reported to cause kswapd to spin at 100% CPU usage when fadump was enabled. The old code happened to deal with the situation of a populated node with zero free pages by co-incidence but the current code tries to reclaim populated zones without realising that is impossible. We cannot just convert populated_zone() as many existing users really need to check for present_pages. This patch introduces a managed_zone() helper and uses it in the few cases where it is critical that the check is made for managed pages -- zonelist construction and page reclaim.

2016-09-01kconfig: tinyconfig: provide whole choice blocks to avoid warningsArnd Bergmann
Using "make tinyconfig" produces a couple of annoying warnings that show up for build test machines all the time: .config:966:warning: override: NOHIGHMEM changes choice state .config:965:warning: override: SLOB changes choice state .config:963:warning: override: KERNEL_XZ changes choice state .config:962:warning: override: CC_OPTIMIZE_FOR_SIZE changes choice state .config:933:warning: override: SLOB changes choice state .config:930:warning: override: CC_OPTIMIZE_FOR_SIZE changes choice state .config:870:warning: override: SLOB changes choice state .config:868:warning: override: KERNEL_XZ changes choice state .config:867:warning: override: CC_OPTIMIZE_FOR_SIZE changes choice state I've made a previous attempt at fixing them and we discussed a number of alternatives. I tried changing the Makefile to use "merge_config.sh -n $(fragment-list)" but couldn't get that to work properly. This is yet another approach, based on the observation that we do want to see a warning for conflicting 'choice' options, and that we can simply make them non-conflicting by listing all other options as disabled. This is a trivial patch that we can apply independent of plans for other changes.

2016-09-01kexec: fix double-free when failing to relocate the purgatoryThiago Jung Bauermann
If kexec_apply_relocations fails, kexec_load_purgatory frees pi->sechdrs and pi->purgatory_buf.

2016-09-01mm, oom: prevent premature OOM killer invocation for high order requestMichal Hocko
There have been several reports about pre-mature OOM killer invocation in 4.7 kernel when order-2 allocation request (for the kernel stack) invoked OOM killer even during basic workloads (light IO or even kernel compile on some filesystems). In all reported cases the memory is fragmented and there are no order-2+ pages available. There is usually a large amount of slab memory (usually dentries/inodes) and further debugging has shown that there are way too many unmovable blocks which are skipped during the compaction. Multiple reporters have confirmed that the current linux-next which includes [1] and [2] helped and OOMs are not reproducible anymore. A simpler fix for the late rc and stable is to simply ignore the compaction feedback and retry as long as there is a reclaim progress and we are not getting OOM for order-0 pages. We already do that for CONFING_COMPACTION=n so let's reuse the same code when compaction is enabled as well.

2016-09-01tcp: fastopen: fix rcv_wup initialization for TFO server on SYN/dataNeal Cardwell
Yuchung noticed that on the first TFO server data packet sent after the (TFO) handshake, the server echoed the TCP timestamp value in the SYN/data instead of the timestamp value in the final ACK of the handshake. This problem did not happen on regular opens. The tcp_replace_ts_recent() logic that decides whether to remember an incoming TS value needs tp->rcv_wup to hold the latest receive sequence number that we have ACKed (latest tp->rcv_nxt we have ACKed). This commit fixes this issue by ensuring that a TFO server properly updates tp->rcv_wup to match tp->rcv_nxt at the time it sends a SYN/ACK for the SYN/data.

This patch handles the errata in a different way and eliminates issues with earlier approach, TSO packet is submitted to HW with post_cqe=0, so that no CQE is posted upon completion of transmission of TSO packet but a additional HDR + IMMEDIATE descriptors are added to SQ due to which a CQE is posted and will have required info to be used while cleanup in napi. This way only one CQE is posted for a TSO packet. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-09-01net: thunderx: Fix for HW issue while padding TSO packetSunil Goutham
There is a issue in HW where-in while sending GSO sized pkts as part of TSO, if pkt len falls below configured min packet size i.e 60, NIC will zero PAD packet and also updates IP total length. Hence set this value to lessthan min pkt size of MAC + IP + TCP headers, BGX will anyway do the padding to transmit 64 byte pkt including FCS.

2016-09-01i40e: Fix kernel panic on enable/disable LLDPDave Ertman
If DCB is configured on the link partner switch with an unsupported traffic class configuration (e.g. non-contiguous TCs), the driver is flagging DCB as disabled. But, for future DCB LLDPDUs, the driver was checking if the interface was DCB capable instead of enabled. This was causing a kernel panic when LLDP was enabled/disabled on the link partner switch. This patch corrects the situation by having the LLDP event handler check the correct flag in the pf structure. It also cleans up the setting and clearing of the enabled flag for other checks.

2016-09-01ASoC: dapm: Fix kcontrol creation for output driver widgetChen-Yu Tsai
Commit d88429a695a4 ("ASoC: dapm: Add output driver widget") added the snd_soc_dapm_out_drv ID for the output driver widget, which is the same as the PGA widget, with a later power sequence number. Commit 19a2557b76d6 ("ASoC: dapm: Add kcontrol support for PGAs") then added kcontrol support for PGA widgets, but failed to account for output driver widgets. Attempts to use kcontrols with output driver widgets result in silent failures, with the developer having little idea about what went on. Add snd_soc_dapm_out_drv to the switch/case block under snd_soc_dapm_pga in dapm_create_or_share_kcontrol, since they are essentially the same.

In sst_prepare_and_post_msg(), when a response is received in "block", the following code gets executed: *data = kzalloc(block->size, GFP_KERNEL); memcpy(data, (void *) block->data, block->size); The memcpy() call overwrites the content of the *data pointer instead of filling the newly-allocated memory (which pointer is hold by *data).
