      xhci: add traces for debug messages in xhci_address_device() · 84a99f6f
      Xenia Ragiadakou 提交于
      This patch declares an event class for trace events that
      trace messages with variadic arguments, called xhci_log_msg,
      and defines a trace event for tracing the debug messages in
      xhci_address_device() function, called xhci_dbg_address.
      
      In order to implement this type of trace events, a wrapper function,
      called xhci_dbg_trace(), was created that records the format string
      and variadic arguments into a va_format structure which is passed as
      argument to the tracepoints of the class xhci_log_msg.
      
      All the xhci_dbg() calls in xhci_address_device() are replaced
      with calls to xhci_dbg_trace(). The functionality of xhci_dbg()
      log messages was not removed though, but it is placed inside
      xhci_dbg_trace().
      
      This trace event aims to give the ability to the user or the
      developper to isolate and trace the debug messages generated
      when an Address Device Command is issued to xHC.

      xhci: remove CONFIG_USB_XHCI_HCD_DEBUGGING and unused code · b2497509
      Xenia Ragiadakou 提交于
      CONFIG_USB_XHCI_HCD_DEBUGGING option is used to enable
      verbose debugging output for the xHCI host controller
      driver.
      
      In the current version of the xhci-hcd driver, this
      option must be turned on, in order for the debugging
      log messages to be displayed, and users may need to
      recompile the linux kernel to obtain debugging
      information that will help them track down problems.
      
      This patch removes the above debug option to enable
      debugging log messages at all times.
      The aim of this is to rely on the debugfs and the
      dynamic debugging feature for fine-grained management
      of debugging messages and to not force users to set
      the debug config option and compile the linux kernel
      in order to have access in that information.
      
      This patch, also, removes the XHCI_DEBUG symbol and the
      functions dma_to_stream_ring(), xhci_test_radix_tree()
      and xhci_event_ring_work() that are not useful anymore.

      xhci: replace printk(KERN_DEBUG ...) · 5c1127d3
      Xenia Ragiadakou 提交于
      This patch replaces the calls to printk(KERN_DEBUG ...)
      with either calls to xhci_dbg() or calls to pr_debug(),
      depending on whether the xhci_hcd structure is available
      at callsite, so that the correspoding debugging messages
      are not enabled by default when CONFIG_DYNAMIC_DEBUG option
      is set but rather can be enabled dynamically taking advantage
      of the dynamic debugging feature.
      
      Also, it adds a newline at the end of debugging messages in
      case there is not, so that messages don't appear broken
      when printed.

      xhci: replace xhci_info() with xhci_dbg() · 38a532a6
      Xenia Ragiadakou 提交于
      This patch replaces the calls to xhci_info() with calls to
      xhci_dbg() and removes the unused xhci_info() definition
      from xhci-hcd.
      
      By replacing the xhci_info() with xhci_dbg(), the calls to
      dev_info() are replaced with calls to dev_dbg() so that
      their output can be dynamically controlled via the dynamic
      debugging mechanism.

      The reason for this is that install_special_mapping() expects the

      netlabel: use domain based selectors when address based selectors are not available · 6a8b7f0c
      Paul Moore 提交于
      NetLabel has the ability to selectively assign network security labels
      to outbound traffic based on either the LSM's "domain" (different for
      each LSM), the network destination, or a combination of both.  Depending
      on the type of traffic, local or forwarded, and the type of traffic
      selector, domain or address based, different hooks are used to label the
      traffic; the goal being minimal overhead.
      
      Unfortunately, there is a bug such that a system using NetLabel domain
      based traffic selectors does not correctly label outbound local traffic
      that is not assigned to a socket.  The issue is that in these cases
      the associated NetLabel hook only looks at the address based selectors
      and not the domain based selectors.  This patch corrects this by
      checking both the domain and address based selectors so that the correct
      labeling is applied, regardless of the configuration type.
      
      In order to acomplish this fix, this patch also simplifies some of the
      NetLabel domainhash structures to use a more common outbound traffic
      mapping type: struct netlbl_dommap_def.  This simplifies some of the code
      in this patch and paves the way for further simplifications in the
      future.

      net: check net.core.somaxconn sysctl values · 5f671d6b
      Roman Gushchin 提交于
      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

      htb: fix sign extension bug · cbd37556
      stephen hemminger 提交于
      When userspace passes a large priority value
      the assignment of the unsigned value hopt->prio
      to  signed int cl->prio causes cl->prio to become negative and the
      comparison is with TC_HTB_NUMPRIO is always false.
      
      The result is that HTB crashes by referencing outside
      the array when processing packets. With this patch the large value
      wraps around like other values outside the normal range.

      Pull powerpc fixes from Ben Herrenschmidt:
       "Here is not quite a handful of powerpc fixes for rc3.
      
        The windfarm fix is a regression fix (though not a new one), the PMU
        interrupt rename is not a fix per-se but has been submitted a long
        time ago and I kept forgetting to put it in (it puts us back in sync
        with x86), the other perf bit is just about putting an API/ABI bit
        definition in the right place for userspace to consume, and finally,
        we have a fix for the VPHN (Virtual Partition Home Node) feature
        (notification that the hypervisor is moving nodes around) which could
        cause lockups so we may as well fix it now"
