fd1232b Mikulas Patocka 09 April 2014, 01:52:05 UTC sym53c8xx_2: Set DID_REQUEUE return code when aborting squeue This patch fixes I/O errors with the sym53c8xx_2 driver when the disk returns QUEUE FULL status. When the controller encounters an error (including QUEUE FULL or BUSY status), it aborts all not yet submitted requests in the function sym_dequeue_from_squeue. This function aborts them with DID_SOFT_ERROR. If the disk has full tag queue, the request that caused the overflow is aborted with QUEUE FULL status (and the scsi midlayer properly retries it until it is accepted by the disk), but the sym53c8xx_2 driver aborts the following requests with DID_SOFT_ERROR --- for them, the midlayer does just a few retries and then signals the error up to sd. The result is that disk returning QUEUE FULL causes request failures. The error was reproduced on 53c895 with COMPAQ BD03685A24 disk (rebranded ST336607LC) with command queue 48 or 64 tags. The disk has 64 tags, but under some access patterns it return QUEUE FULL when there are less than 64 pending tags. The SCSI specification allows returning QUEUE FULL anytime and it is up to the host to retry.

18aa0da Paul Mackerras 11 April 2014, 06:43:35 UTC powerpc: Don't try to set LPCR unless we're in hypervisor mode Commit 8f619b5429d9 ("powerpc/ppc64: Do not turn AIL (reloc-on interrupts) too early") added code to set the AIL bit in the LPCR without checking whether the kernel is running in hypervisor mode. The result is that when the kernel is running as a guest (i.e., under PowerKVM or PowerVM), the processor takes a privileged instruction interrupt at that point, causing a panic. The visible result is that the kernel hangs after printing "returning from prom_init". This fixes it by checking for hypervisor mode being available before setting LPCR. If we are not in hypervisor mode, we enable relocation-on interrupts later in pSeries_setup_arch using the H_SET_MODE hcall.

One was a late fix and the other a consequence of overlooking the whole requeuing logic.

454fd35 Linus Torvalds 13 April 2014, 00:31:22 UTC Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net Pull yet more networking updates from David Miller: 1) Various fixes to the new Redpine Signals wireless driver, from Fariya Fatima. 2) L2TP PPP connect code takes PMTU from the wrong socket, fix from Dmitry Petukhov. 3) UFO and TSO packets differ in whether they include the protocol header in gso_size, account for that in skb_gso_transport_seglen(). From Florian Westphal. 4) If VLAN untagging fails, we double free the SKB in the bridging output path. From Toshiaki Makita. 5) Several call sites of sk->sk_data_ready() were referencing an SKB just added to the socket receive queue in order to calculate the second argument via skb->len. This is dangerous because the moment the skb is added to the receive queue it can be consumed in another context and freed up. It turns out also that none of the sk->sk_data_ready() implementations even care about this second argument. So just kill it off and thus fix all these use-after-free bugs as a side effect. 6) Fix inverted test in tcp_v6_send_response(), from Lorenzo Colitti. 7) pktgen needs to do locking properly for LLTX devices, from Daniel Borkmann. 8) xen-netfront driver initializes TX array entries in RX loop :-) From Vincenzo Maffione. 9) After refactoring, some tunnel drivers allow a tunnel to be configured on top itself.

Mark fixes an issue with ixgbe and ixgbevf by adding a bit to indicate when workqueues have been initialized. This permits the register read error handling from attempting to use them prior to that, which also generates warnings. Checking for a detected removal after initializing the work queues allows the probe function to return an error without getting the workqueue involved. Further, if the error_detected callback is entered before the workqueues are initialized, exit without recovery since the device initialization was so truncated. Francois Romieu provides several patches to all the drivers to remove the open coded skb_cow_head. Jakub Kicinski provides a fix for igb where last_rx_timestamp should be updated only when Rx time stamp is read.

0a7418f Linus Torvalds 12 April 2014, 20:06:10 UTC Merge tag 'trace-3.15-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull more tracing updates from Steven Rostedt: "This includes the final patch to clean up and fix the issue with the design of tracepoints and how a user could register a tracepoint and have that tracepoint not be activated but no error was shown. The design was for an out of tree module but broke in tree users. The clean up was to remove the saving of the hash table of tracepoint names such that they can be enabled before they exist (enabling a module tracepoint before that module is loaded). This added more complexity than needed. The clean up was to remove that code and just enable tracepoints that exist or fail if they do not. This removed a lot of code as well as the complexity that it brought. As a side effect, instead of registering a tracepoint by its name, the tracepoint needs to be registered with the tracepoint descriptor. This removes having to duplicate the tracepoint names that are enabled. The second patch was added that simplified the way modules were searched for. This cleanup required changes that were in the 3.15 queue as well as some changes that were added late in the 3.14-rc cycle. This final change waited till the two were merged in upstream and then the change was added and full tests were run.

This makes usage such as bridging impossible, which is a shame on virtualization capable HW such as the Allwinner A20. The fix is fairly simple: move the RX setup code to the ndo_set_rx_mode vector, and add the required HW configuration when IFF_PROMISC is passed by the core code. This has been tested on a generic A20 box running a few virtual machines hanging off a bridge with the EMAC chip as the link to the outside world.

Set this pointer in ft_tport_create, or the unlinking won't happen in ft_del_tpg and tport->tpg will reference a deleted object. This patch sets tpg->tport in ft_tport_create, because that's what ft_del_tpg checks, and is the only way to get back to the tport to clear tport->tpg. The bug was occuring when: - lport created, tport (our per-lport, per-provider context) is allocated. tport->tpg = NULL - tpg created - a PRLI is received. ft_tport_create is called, tpg is found and tport->tpg is set - tpg removed. ft_tpg is freed in ft_del_tpg. Since tpg->tport was not set, tport->tpg is not cleared and points at freed memory - Future calls to ft_tport_create return tport via first conditional, instead of searching for new tpg by calling ft_lport_find_tpg. tport->tpg is still invalid, and will access freed memory. see https://bugzilla.redhat.com/show_bug.cgi?id=1071340 Cc: stable@vger.kernel.org # 3.0+ Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org> 11 April 2014, 22:27:23 UTC

When the sess_cmd_list is searched, since the ABTS and the FCP_CMND being aborted (that just completed) both have the same OXID, TFO->get_task_tag(TMR) returns a value that matches tmr->ref_task_tag (from TFO->get_task_tag(FCP_CMND)), and the Abort Task tries to abort itself. When this occurs, transport_wait_for_tasks() hangs forever since the TMR is waiting for itself to finish.

Specifically: 1. If a SYN comes in from a global address, and sk_bound_dev_if is not set, the routing lookup has oif set to the interface the SYN came in on. Instead, it should have oif unset, because for global addresses, the incoming interface doesn't necessarily have any bearing on the interface the SYN+ACK is sent out on. 2. If a SYN comes in from a link-local address, and sk_bound_dev_if is set, the routing lookup has oif set to the interface the SYN came in on. Instead, it should have oif set to sk_bound_dev_if, because that's what the application requested.

676d236 David S. Miller 11 April 2014, 20:15:36 UTC net: Fix use after free by removing length arg from sk_data_ready callbacks. Several spots in the kernel perform a sequence like: skb_queue_tail(&sk->s_receive_queue, skb); sk->sk_data_ready(sk, skb->len); But at the moment we place the SKB onto the socket receive queue it can be consumed and freed up. So this skb->len access is potentially to freed up memory. Furthermore, the skb->len can be modified by the consumer so it is possible that the value isn't accurate. And finally, no actual implementation of this callback actually uses the length argument. And since nobody actually cared about it's value, lots of call sites pass arbitrary values in such as '0' and even '1'. So just remove the length argument from the callback, that way there is no confusion whatsoever and all of these use-after-free cases get fixed as a side effect.

b3b42ac H. Peter Anvin 16 March 2014, 22:31:54 UTC x86-64, modify_ldt: Ban 16-bit segments on 64-bit kernels The IRET instruction, when returning to a 16-bit segment, only restores the bottom 16 bits of the user space stack pointer. We have a software workaround for that ("espfix") for the 32-bit kernel, but it relies on a nonzero stack segment base which is not available in 32-bit mode. Since 16-bit support is somewhat crippled anyway on a 64-bit kernel (no V86 mode), and most (if not quite all) 64-bit processors support virtualization for the users who really need it, simply reject attempts at creating a 16-bit segment when running on top of a 64-bit kernel.

7dc8660 Jakub Kicinski 02 April 2014, 10:33:17 UTC e1000: remove debug messages with function names e1000_hw.c contains a lot of debug messages which print name of invoked function and contain no new line character at the end. Remove them as equivalent information can be nowadays obtained using function tracer.

ea69956 Mark Rustad 12 March 2014, 00:38:51 UTC ixgbevf: Add bit to mark work queue initialization An indication of work queue initialization is needed. This is because register accesses prior to that time can detect a removal and attempt to schedule the watchdog task. Adding the __IXGBEVF_WORK_INIT bit allows this to be checked and if not set prevent the watchdog task scheduling. By checking for a removal right after initialization, the probe can be failed at that point without getting the watchdog task involved.

34bf6ef Dave Hansen 08 April 2014, 20:44:27 UTC mm: slab/slub: use page->list consistently instead of page->lru 'struct page' has two list_head fields: 'lru' and 'list'. Conveniently, they are unioned together. This means that code can use them interchangably, which gets horribly confusing like with this nugget from slab.c: > list_del(&page->lru); > if (page->active == cachep->num) > list_add(&page->list, &n->slabs_full); This patch makes the slab and slub code use page->lru universally instead of mixing ->list and ->lru. So, the new rule is: page->lru is what the you use if you want to keep your page on a list. Don't like the fact that it's not called ->list? Too bad.

0534af0 WANG Chao 10 March 2014, 14:52:00 UTC x86, calgary: Use 8M TCE table size by default New kexec-tools wants to pass kdump kernel needed memmap via E820 directly, instead of memmap=exactmap. This makes saved_max_pfn not be passed down to 2nd kernel. To keep 1st kernel and 2nd kernel using the same TCE table size, Muli suggest to hard code the size to max (8M). We can't get rid of saved_max_pfn this time, for backward compatibility with old first kernel and new second kernel. However new first kernel and old second kernel can not work unfortunately. v2->v1: - retain saved_max_pfn so new 2nd kernel can work with old 1st kernel from Vivek Signed-off-by: WANG Chao <chaowang@redhat.com> Acked-by: Vivek Goyal <vgoyal@redhat.com> Acked-by: Muli Ben-Yehuda <mulix@mulix.org> Acked-by: Jon Mason <jdmason@kudzu.us> Link: http://lkml.kernel.org/r/1394463120-26999-1-git-send-email-chaowang@redhat.com Signed-off-by: H.
