      [SCSI] csiostor: off by one error · 4f8d1bd2

      We need to store PROTO_ERR_IMPL_LOGO (26) things here, but the
      first element isn't used so the array should have 27 elements.
      This matches fwevt_to_rnevt[] which has 27 elements.
      
      The patch solves a Smatch static checker warning on my system:

      incorrectly assumes that abort failed and performes recovery by issuing

      [SCSI] fnic: FIP VLAN Discovery Feature Support · d3c995f1
      Hiral Patel 提交于
      FIP VLAN discovery discovers the FCoE VLAN that will be used by all other FIP
      protocols as well as by the FCoE encapsulation for Fibre Channel payloads on
      the established virtual link. One of the goals of FC-BB-5 was to be as
      nonintrusive as possible on initiators and targets, and therefore FIP VLAN
      discovery occurs in the native VLAN used by the initiator or target to
      exchange Ethernet traffic. The FIP VLAN discovery protocol is the only FIP
      protocol running on the native VLAN; all other FIP protocols run on the
      discovered FCoE VLANs.
      
      If an administrator has manually configured FCoE VLANs on ENodes and FCFs,
      there is no need to use this protocol. FIP and FCoE will run over the
      configured VLANs.
      
      An ENode without FCoE VLANs configuration would use this automated discovery
      protocol to discover over which VLANs FCoE is running.
      
      The ENode sends a FIP VLAN discovery request to a multicast MAC address called
      All-FCF-MACs, which is a multicast MAC address to which all FCFs listen.
      
      All FCFs that can be reached in the native VLAN of the ENode are expected to
      respond on the same VLAN with a response that lists one or more FCoE VLANs
      that are available for the ENode's VN_Port login. This protocol has the sole
      purpose of allowing the ENode to discover all the available FCoE VLANs.
      
      Now the ENode may enable a subset of these VLANs for FCoE Running the FIP
      protocol in these VLANs on a per VLAN basis. And FCoE data transactions also
      would occur on this VLAN. Hence, Except for FIP VLAN discovery, all other FIP
      and FCoE traffic runs on the selected FCoE VLAN.  Its only the FIP VLAN
      Discovery protocol that is permitted to run on the Default native VLAN of the
      system.
      
      [**** NOTE ****]
      We are working on moving this feature definitions and functionality to libfcoe
      module. We need this patch to be approved, as Suse is looking forward to merge
      this feature in SLES 11 SP3 release.  Once this patch is approved, we will
      submit patch which should move vlan discovery feature to libfoce.

      af_unix: fix a fatal race with bit fields · 60bc851a
      Eric Dumazet 提交于
      Using bit fields is dangerous on ppc64/sparc64, as the compiler [1]
      uses 64bit instructions to manipulate them.
      If the 64bit word includes any atomic_t or spinlock_t, we can lose
      critical concurrent changes.
      
      This is happening in af_unix, where unix_sk(sk)->gc_candidate/
      gc_maybe_cycle/lock share the same 64bit word.
      
      This leads to fatal deadlock, as one/several cpus spin forever
      on a spinlock that will never be available again.
      
      A safer way would be to use a long to store flags.
      This way we are sure compiler/arch wont do bad things.
      
      As we own unix_gc_lock spinlock when clearing or setting bits,
      we can use the non atomic __set_bit()/__clear_bit().
      
      recursion_level can share the same 64bit location with the spinlock,
      as it is set only with this spinlock held.

      This resulted from my commit ca99ca14 which introduced a mutex_trylock
      operation in a path that could execute in interrupt context.  When mutex
      debugging is enabled, the above warns the user when we are in fact
      exectuting in interrupt context
      interrupt context.
      
      After some discussion, It seems that a semaphore is the proper mechanism to use
      here.  While mutexes are defined to be unusable in interrupt context, no such
      condition exists for semaphores (save for the fact that the non blocking api
      calls, like up and down_trylock must be used when in irq context).

      init: Do not warn on non-zero initcall return · bf5d770b
      Steven Rostedt 提交于
      Commit f91eb62f ("init: scream bloody murder if interrupts are
      enabled too early") added three new warnings.  The first two seemed
      reasonable, but the third included a warning when an initcall returned
      non-zero.  Although, the third WARN() does include an imbalanced preempt
      disabled, or irqs disable, it shouldn't warn if it only had an initcall
      that just returns non-zero.
      
      In fact, according to Linus, it shouldn't print at all.  As it only
      prints with initcall_debug set, and that already shows enough
      information to fix things.
