26c57ef Johannes Thumshirn 18 June 2013, 15:19:45 UTC watchdog: New watchdog driver for MEN A21 watchdogs This patch adds the driver for the watchdog devices found on MEN Mikro Elektronik A21 VMEbus CPU Carrier Boards. It has DT-support and uses the watchdog framework.

6910ceb Russell King 18 June 2013, 16:20:32 UTC Watchdog: fix clearing of the watchdog interrupt The bits in BRIDGE_CAUSE are documented as RW0C - read, write 0 to clear. If we read the register, mask off the watchdog bit, and write it back, we're actually clearing every interrupt which wasn't pending at the time we read the register - and that is racy. Fix this to only write ~WATCHDOG_BIT to the register, which means we write as zero only the watchdog bit.

fa142ff Russell King 18 June 2013, 16:19:32 UTC Watchdog: allow orion_wdt to be built for Dove The watchdog infrastructure in Dove is no different from that in Orion5x or Kirkwood, so let's enable it for Dove. The only things missing are a few register settings in Dove's bridge-regs.h. Rather than duplicating the same register bit masks for the RSTOUTn_MASK and BRIDGE_CAUSE registers, move the definitions into the watchdog driver itself.

6e63a3a Viresh Kumar 19 June 2013, 15:08:58 UTC watchdog: delete mpcore_wdt driver Interrupt request doesn't use the right API: The TWD watchdog uses a per-cpu interrupt (usually interrupt #30), and the GIC configuration should flag it as such. With this setup, request_irq() should fail, and the right API is request_percpu_irq(), together with enable_percpu_irq()/disable_percpu_irq(). Nothing ensures the userspace ioctl() will end-up kicking the watchdog on the right CPU. There are no users of this driver since a long time and it makes more sense to get rid of it as nobody is looking to fix it. In case somebody wakes up after this has been removed and needs it, please revert this driver and pick these updates (These were never pushed to mainline): http://comments.gmane.org/gmane.linux.ports.arm.kernel/245998 Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> 11 July 2013, 19:47:58 UTC

fcf9567 Hector Palacios 08 April 2013, 15:06:32 UTC watchdog: core: don't try to stop device if not running A watchdog device may be stopped from userspace using WDIOC_SETOPTIONS ioctl and flag WDIOS_DISABLECARD. If the device is closed after this operation, watchdog_release() is called and status bits checked for stopping it. Besides, if the device has not been unregistered a critical message "watchdog did not stop!" is printed, although the ioctl may have successfully stopped it already. Without the patch a user application sample code like this will successfully stop the watchdog, but the kernel will output the message "watchdog did not stop!": wd_fd = open("/dev/watchdog", O_RDWR); flags = WDIOS_DISABLECARD; ioctl(wd_fd, WDIOC_SETOPTIONS, &flags); close(wd_fd); Signed-off-by: Hector Palacios <hector.palacios@digi.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> 11 July 2013, 19:14:39 UTC

It is completely and utterly broken. Module install should not build any files, and adding broken dependencies to "help" it build files is complete and utter sh*t. The kernel should not be built by root, and "make install" and "make module_install" (that for obvious reasons need to be run as root) absolutely must not build any files. They should only ever copy the already-built files over. So having dependencies for the install targets is wrong, wrong, wrong. If you try to install a kernel without building it first, you *should* get errors. The build system shouldn't try to help root build the files.

2b28111 Seth Jennings 10 July 2013, 23:05:03 UTC zswap: add to mm/ zswap is a thin backend for frontswap that takes pages that are in the process of being swapped out and attempts to compress them and store them in a RAM-based memory pool. This can result in a significant I/O reduction on the swap device and, in the case where decompressing from RAM is faster than reading from the swap device, can also improve workload performance. It also has support for evicting swap pages that are currently compressed in zswap to the swap device on an LRU(ish) basis. This functionality makes zswap a true cache in that, once the cache is full, the oldest pages can be moved out of zswap to the swap device so newer pages can be compressed and stored in zswap.

4e2e277 Seth Jennings 10 July 2013, 23:04:55 UTC zbud: add to mm/ zbud is an special purpose allocator for storing compressed pages. It is designed to store up to two compressed pages per physical page. While this design limits storage density, it has simple and deterministic reclaim properties that make it preferable to a higher density approach when reclaim will be used. zbud works by storing compressed pages, or "zpages", together in pairs in a single memory page called a "zbud page". The first buddy is "left justifed" at the beginning of the zbud page, and the last buddy is "right justified" at the end of the zbud page. The benefit is that if either buddy is freed, the freed buddy space, coalesced with whatever slack space that existed between the buddies, results in the largest possible free region within the zbud page. zbud also provides an attractive lower bound on density. The ratio of zpages to zbud pages can not be less than 1. This ensures that zbud can never "do harm" by using more pages to store zpages than the uncompressed zpages would have used on their own. This implementation is a rewrite of the zbud allocator internally used by zcache in the driver/staging tree. The rewrite was necessary to remove some of the zcache specific elements that were ingrained throughout and provide a generic allocation interface that can later be used by zsmalloc and others. This patch adds zbud to mm/ for later use by zswap.

The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ... 10 July 2013, 01:24:39 UTC

Since this seems to be a generic problem with gcc-4.7.x (and below), it's better to simplify the fault handlers in pa_memcpy to avoid this problem. Here is a simple reproducer for the problem: int main(int argc, char **argv) { int fd, nbytes; struct iovec wr_iovec[] = { { "TEST STRING ",32}, { (char*)0x40005000,32} }; // random memory. fd = open(DATA_FILE, O_RDWR | O_CREAT, 0666); nbytes = writev(fd, wr_iovec, 2); printf("return value = %d, errno %d (%s)\n", nbytes, errno, strerror(errno)); return 0; } In addition, John David Anglin wrote: There is no gcc PR as pa_memcpy is not legitimate C code. There is an implicit assumption that certain variables will contain correct values when an exception occurs and the code randomly jumps to one of the exception blocks. There is no guarantee of this. If a PR was filed, it would likely be marked as invalid.

e8d8fc2 John David Anglin 29 June 2013, 20:42:12 UTC parisc: Ensure volatile space register %sr1 is not clobbered I still see the occasional random segv on rp3440. Looking at one of these (a code 15), it appeared the problem must be with the cache handling of anonymous pages. Reviewing this, I noticed that the space register %sr1 might be being clobbered when we flush an anonymous page. Register %sr1 is used for TLB purges in a couple of places. These purges are needed on PA8800 and PA8900 processors to ensure cache consistency of flushed cache lines. The solution here is simply to move the %sr1 load into the TLB lock region needed to ensure that one purge executes at a time on SMP systems. This was already the case for one use. After a few days of operation, I haven't had a random segv on my rp3440.

785bf6f Jonas Gorski 07 July 2013, 22:44:55 UTC net: mv643xx_eth: do not use port number as platform device id The port number is only local to the ethernet block, not global, so there can be two ethernet blocks both using the same port, like kirkwood with both using port 0. Fix this by using the array index offset for the allocated platform devices as the id. Signed-off-by: Jonas Gorski <jogo@openwrt.org> Signed-off-by: David S.

8c2f414 Daniel Borkmann 09 July 2013, 14:17:04 UTC net: sctp: confirm route during forward progress This fix has been proposed originally by Vlad Yasevich. He says: When SCTP makes forward progress (receives a SACK that acks new chunks, renegs, or answeres 0-window probes) or when HB-ACK arrives, mark the route as confirmed so we don't unnecessarily send NUD probes. Having a simple SCTP client/server that exchange data chunks every 1sec, without this patch ARP requests are sent periodically every 40-60sec. With this fix applied, an ARP request is only done once right at the "session" beginning. Also, when clearing the related ARP cache entry manually during the session, a new request is correctly done. I have only "backported" this to net-next and tested that it works, so full credit goes to Vlad.

e1d6fbc David S. Miller 09 July 2013, 19:45:43 UTC virtio_net: fix race in RX VQ processing Michael S. Tsirkin says: ==================== Jason Wang reported a race in RX VQ processing: virtqueue_enable_cb is called outside napi lock, violating virtio serialization rules. The race has been there from day 1, but it got especially nasty in 3.0 when commit a5c262c5fd83ece01bd649fb08416c501d4c59d7 "virtio_ring: support event idx feature" added more dependency on vq state. Please review, and consider for 3.11 and stable. Changes from v1: - Added Jason's Tested-by tag - minor coding style fix ==================== Signed-off-by: David S.

cbdadbb Michael S. Tsirkin 09 July 2013, 05:13:04 UTC virtio_net: fix race in RX VQ processing virtio net called virtqueue_enable_cq on RX path after napi_complete, so with NAPI_STATE_SCHED clear - outside the implicit napi lock. This violates the requirement to synchronize virtqueue_enable_cq wrt virtqueue_add_buf. In particular, used event can move backwards, causing us to lose interrupts. In a debug build, this can trigger panic within START_USE. Jason Wang reports that he can trigger the races artificially, by adding udelay() in virtqueue_enable_cb() after virtio_mb(). However, we must call napi_complete to clear NAPI_STATE_SCHED before polling the virtqueue for used buffers, otherwise napi_schedule_prep in a callback will fail, causing us to lose RX events. To fix, call virtqueue_enable_cb_prepare with NAPI_STATE_SCHED set (under napi lock), later call virtqueue_poll with NAPI_STATE_SCHED clear (outside the lock).

cc22988 Michael S. Tsirkin 09 July 2013, 10:19:18 UTC virtio: support unlocked queue poll This adds a way to check ring empty state after enable_cb outside any locks. Will be used by virtio_net. Note: there's room for more optimization: caller is likely to have a memory barrier already, which means we might be able to get rid of a barrier here. Deferring this optimization until we do some benchmarking. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net> 09 July 2013, 19:45:37 UTC
