      rtc: s5m: consolidate two device type switch statements · a0347f20
      Krzysztof Kozlowski authored
      In probe the configuration of driver for different chipsets was done in
      two switch (pdata->device_type) statements.  Consolidate them into one
      switch statement to increase code readability.
      
      Additionally check the return value of regmap_irq_get_virq and exit
      probe on error.

      rtc: s5m: add support for S2MPS14 RTC · 0c5deb1e
      Krzysztof Kozlowski authored
      Add support for S2MPS14 to the rtc-s5m driver.  Differences in S2MPS14
      (in comparison to S5M8767):
      
       - Layout of registers
       - Lack of century support for time and alarms (7 registers used for
         storing time/alarm)
       - Two buffer control registers: WUDR and RUDR
       - No register for enabling writing time
       - RTC interrupts are reported in main PMIC I2C device

      rtc: s5m: remove undocumented time init on first boot · fe787a5b
      Krzysztof Kozlowski authored
      Remove the code for initializing time if this is first boot.
      
      The code for detecting first boot uses undocumented field RTC_TCON in
      RTC_UDR_CON register.  According to S5M8767's datasheet this field is
      reserved.  On S2MPS14 it is not documented at all.
      
      On device first boot the registers will be initialized with reset value
      (2000-01-01 00:00:00).
      
      The code might work on S5M8763 but still this does not look like a task
      for RTC driver.

      gcov: add support for GCC 4.9 · a992bf83
      Yuan Pengfei authored
      This patch handles the gcov-related changes in GCC 4.9:
      
        A new counter (time profile) is added. The total number is 9 now.
      
        A new profile merge function __gcov_merge_time_profile is added.
      
      See gcc/gcov-io.h and libgcc/libgcov-merge.c
      
      For the first change, the layout of struct gcov_info is affected.
      
      For the second one, a dummy function is added to kernel/gcov/base.c
      similarly.

      decode_stacktrace: make stack dump output useful again · dbd1abb2
      Sasha Levin authored
      Right now when people try to report issues in the kernel they send stack
      dumps to eachother, which looks something like this:
      
        [    6.906437]  [<ffffffff811f0e90>] ? backtrace_test_irq_callback+0x20/0x20
        [    6.907121]  [<ffffffff84388ce8>] dump_stack+0x52/0x7f
        [    6.907640]  [<ffffffff811f0ec8>] backtrace_regression_test+0x38/0x110
        [    6.908281]  [<ffffffff813596a0>] ? proc_create_data+0xa0/0xd0
        [    6.908870]  [<ffffffff870a8040>] ? proc_modules_init+0x22/0x22
        [    6.909480]  [<ffffffff810020c2>] do_one_initcall+0xc2/0x1e0
        [...]
      
      However, most of the text you get is pure garbage.
      
      The only useful thing above is the function name.  Due to the amount of
      different kernel code versions and various configurations being used,
      the kernel address and the offset into the function are not really
      helpful in determining where the problem actually occured.
      
      Too often the result of someone looking at a stack dump is asking the
      person who sent it for a translation for one or more 'addr2line'
      translations.  Which slows down the entire process of debugging the
      issue (and really annoying).
      
      The decode_stacktrace script is an attempt to make the output more
      useful and easy to work with by translating all kernel addresses in the
      stack dump into line numbers.  Which means that the stack dump would
      look like this:
      
        [  635.148361]  dump_stack (lib/dump_stack.c:52)
        [  635.149127]  warn_slowpath_common (kernel/panic.c:418)
        [  635.150214]  warn_slowpath_null (kernel/panic.c:453)
        [  635.151031]  _oalloc_pages_slowpath+0x6a/0x7d0
        [  635.152171]  ? zone_watermark_ok (mm/page_alloc.c:1728)
        [  635.152988]  ? get_page_from_freelist (mm/page_alloc.c:1939)
        [  635.154766]  __alloc_pages_nodemask (mm/page_alloc.c:2766)
      
      It's pretty obvious why this is better than the previous stack dump
      before.
      
      Usage is pretty simple:
      
              ./decode_stacktrace.sh [vmlinux] [base path]
      
      Where vmlinux is the vmlinux to extract line numbers from and base path
      is the path that points to the root of the build tree, for example:
      
              ./decode_stacktrace.sh vmlinux /home/sasha/linux/ < input.log > output.log
      
      The stack trace should be piped through it (I, for example, just pipe
      the output of the serial console of my KVM test box through it).

      fs,userns: Change inode_capable to capable_wrt_inode_uidgid · 23adbe12
      Andy Lutomirski authored
      The kernel has no concept of capabilities with respect to inodes; inodes
      exist independently of namespaces.  For example, inode_capable(inode,
      CAP_LINUX_IMMUTABLE) would be nonsense.
      
      This patch changes inode_capable to check for uid and gid mappings and
      renames it to capable_wrt_inode_uidgid, which should make it more
      obvious what it does.
      
      Fixes CVE-2014-4014.

       "The largest piece is a long-overdue rewrite of the xdr code to remove
        some annoying limitations: for example, there was no way to return

        chunks, limiting performance on large directories.
      
        Also:
              - part of Neil Brown's work to make NFS work reliably over the
                loopback interface (so client and server can run on the same
                machine without deadlocks).  The rest of it is coming through
                other trees.
              - cleanup and bugfixes for some of the server RDMA code, from
                Steve Wise.
              - Various cleanup of NFSv4 state code in preparation for an

      RDMA/core: Add support for iWARP Port Mapper user space service · 30dc5e63
      Tatyana Nikolova authored
      This patch adds iWARP Port Mapper (IWPM) Version 2 support.  The iWARP
      Port Mapper implementation is based on the port mapper specification
      section in the Sockets Direct Protocol paper -
      http://www.rdmaconsortium.org/home/draft-pinkerton-iwarp-sdp-v1.0.pdf
      
      Existing iWARP RDMA providers use the same IP address as the native
      TCP/IP stack when creating RDMA connections.  They need a mechanism to
      claim the TCP ports used for RDMA connections to prevent TCP port
      collisions when other host applications use TCP ports.  The iWARP Port
      Mapper provides a standard mechanism to accomplish this.  Without this
      service it is possible for RDMA application to bind/listen on the same
      port which is already being used by native TCP host application.  If
      that happens the incoming TCP connection data can be passed to the
      RDMA stack with error.
      
      The iWARP Port Mapper solution doesn't contain any changes to the
      existing network stack in the kernel space.  All the changes are
      contained with the infiniband tree and also in user space.
      
      The iWARP Port Mapper service is implemented as a user space daemon
      process.  Source for the IWPM service is located at
      http://git.openfabrics.org/git?p=~tnikolova/libiwpm-1.0.0/.git;a=summary
      
      The iWARP driver (port mapper client) sends to the IWPM service the
      local IP address and TCP port it has received from the RDMA
      application, when starting a connection.  The IWPM service performs a
      socket bind from user space to get an available TCP port, called a
      mapped port, and communicates it back to the client.  In that sense,
      the IWPM service is used to map the TCP port, which the RDMA
      application uses to any port available from the host TCP port
      space. The mapped ports are used in iWARP RDMA connections to avoid
      collisions with native TCP stack which is aware that these ports are
      taken. When an RDMA connection using a mapped port is terminated, the
      client notifies the IWPM service, which then releases the TCP port.
      
      The message exchange between the IWPM service and the iWARP drivers
      (between user space and kernel space) is implemented using netlink
      sockets.
      
      1) Netlink interface functions are added: ibnl_unicast() and
         ibnl_mulitcast() for sending netlink messages to user space
      
      2) The signature of the existing ibnl_put_msg() is changed to be more
         generic
      
      3) Two netlink clients are added: RDMA_NL_NES, RDMA_NL_C4IW
         corresponding to the two iWarp drivers - nes and cxgb4 which use
         the IWPM service
      
      4) Enums are added to enumerate the attributes in the netlink
         messages, which are exchanged between the user space IWPM service
         and the iWARP drivers

      in 40f2287b ("IB/mlx4: Implement IB_QP_CREATE_USE_GFP_NOIO").  Fix
      this by passing gfp value down properly.
