      After the locking was moved up to the caller of the get_unbound_pool(),
      out_unlock label doesn't need to do any unlock operation and the name
      became bad, so we just remove this label, and the only usage-site
      "goto out_unlock" is subsituted to "return pool".

      workqueue: remove the stale comment in pwq_unbound_release_workfn() · 29b1cb41
      Lai Jiangshan 提交于
      In 75ccf595 ("workqueue: prepare flush_workqueue() for dynamic
      creation and destrucion of unbound pool_workqueues"), a comment
      about the synchronization for the pwq in pwq_unbound_release_workfn()
      was added. The comment claimed the flush_mutex wasn't strictly
      necessary, it was correct in that time, due to the pwq was protected
      by workqueue_lock.
      
      But it is incorrect now since the wq->flush_mutex was renamed to
      wq->mutex and workqueue_lock was removed, the wq->mutex is strictly
      needed. But the comment was miss-updated when the synchronization
      was changed.
      
      This patch removes the incorrect comments and doesn't add any new
      comment to explain why wq->mutex is needed here, which is definitely
      obvious and wq->pwqs_node has "WQ" notation in its definition which is
      better comment.
      
      The old commit mentioned above also introduced a comment in link_pwq()
      about the synchronization. This comment is also removed in this patch
      since the whole link_pwq() is proteced by wq->mutex.

      workqueue: move rescuer pool detachment to the end · 13b1d625
      Lai Jiangshan 提交于
      In 51697d39 ("workqueue: use generic attach/detach routine for
      rescuers"), The rescuer detaches itself from the pool before put_pwq()
      so that the put_unbound_pool() will not destroy the rescuer-attached
      pool.
      
      It is unnecessary.  worker_detach_from_pool() can be used as the last
      statement to access to the pool just like the regular workers,
      put_unbound_pool() will wait for it to detach and then free the pool.
      
      So we move the worker_detach_from_pool() down, make it coincide with
      the regular workers.

      workqueue: unfold start_worker() into create_worker() · 051e1850
      Lai Jiangshan 提交于
      Simply unfold the code of start_worker() into create_worker() and
      remove the original start_worker() and create_and_start_worker().
      
      The only trade-off is the introduced overhead that the pool->lock
      is released and regrabbed after the newly worker is started.
      The overhead is acceptible since the manager is slow path.
      
      And because this new locking behavior, the newly created worker
      may grab the lock earlier than the manager and go to process
      work items. In this case, the recheck need_to_create_worker() may be
      true as expected and the manager goes to restart which is the
      correct behavior.

      worker_set_flags() has only two callers, each specifying %true and

      This reverts commit e1edf18b.
      
      This patch was a misguided attempt at fixing offb for LE ppc64
      kernels on BE qemu but is just wrong ... it breaks real LE/LE
      setups, LE with real HW, and existing mixed endian systems
      that did the fight thing with the appropriate device-tree
      property. Bad reviewing on my part, sorry.
      
      The right fix is to either make qemu change its endian when
      the guest changes endian (working on that) or to use the
      existing foreign endian support.

      net: sctp: fix permissions for rto_alpha and rto_beta knobs · b58537a1
      Daniel Borkmann 提交于
      Commit 3fd091e7 ("[SCTP]: Remove multiple levels of msecs
      to jiffies conversions.") has silently changed permissions for
      rto_alpha and rto_beta knobs from 0644 to 0444. The purpose of
      this was to discourage users from tweaking rto_alpha and
      rto_beta knobs in production environments since they are key
      to correctly compute rtt/srtt.
      
      RFC4960 under section 6.3.1. RTO Calculation says regarding
      rto_alpha and rto_beta under rule C3 and C4:
      
        [...]
        C3)  When a new RTT measurement R' is made, set
      
             RTTVAR <- (1 - RTO.Beta) * RTTVAR + RTO.Beta * |SRTT - R'|
      
             and
      
             SRTT <- (1 - RTO.Alpha) * SRTT + RTO.Alpha * R'
      
             Note: The value of SRTT used in the update to RTTVAR
             is its value before updating SRTT itself using the
             second assignment. After the computation, update
             RTO <- SRTT + 4 * RTTVAR.
      
        C4)  When data is in flight and when allowed by rule C5
             below, a new RTT measurement MUST be made each round
             trip. Furthermore, new RTT measurements SHOULD be
             made no more than once per round trip for a given
             destination transport address. There are two reasons
             for this recommendation: First, it appears that
             measuring more frequently often does not in practice
             yield any significant benefit [ALLMAN99]; second,
             if measurements are made more often, then the values
             of RTO.Alpha and RTO.Beta in rule C3 above should be
             adjusted so that SRTT and RTTVAR still adjust to
             changes at roughly the same rate (in terms of how many
             round trips it takes them to reflect new values) as
             they would if making only one measurement per
             round-trip and using RTO.Alpha and RTO.Beta as given
             in rule C3. However, the exact nature of these
             adjustments remains a research issue.
        [...]
      
      While it is discouraged to adjust rto_alpha and rto_beta
      and not further specified how to adjust them, the RFC also
      doesn't explicitly forbid it, but rather gives a RECOMMENDED
      default value (rto_alpha=3, rto_beta=2). We have a couple
      of users relying on the old permissions before they got
      changed. That said, if someone really has the urge to adjust
      them, we could allow it with a warning in the log.

      Tom Herbert 提交于
      Geert reported issues regarding checksum complete and UDP.
      The logic introduced in commit 7e3cead5
      ("net: Save software checksum complete") is not correct.
      
      This patch:
      1) Restores code in __skb_checksum_complete_header except for setting
         CHECKSUM_UNNECESSARY. This function may be calculating checksum on
         something less than skb->len.
      2) Adds saving checksum to __skb_checksum_complete. The full packet
         checksum 0..skb->len is calculated without adding in pseudo header.
         This value is saved in skb->csum and then the pseudo header is added
         to that to derive the checksum for validation.
      3) In both __skb_checksum_complete_header and __skb_checksum_complete,
         set skb->csum_valid to whether checksum of zero was computed. This
         allows skb_csum_unnecessary to return true without changing to
         CHECKSUM_UNNECESSARY which was done previously.
      4) Copy new csum related bits in __copy_skb_header.

      patch fixes that. Also, we add BUILD_BUG_ONs in net_gso_ok for several
      GSO constants that were missing to avoid the problem in the future.

      fix __swap_writepage() compile failure on old gcc versions · 05064084

       "Commit 62a8067a ("bio_vec-backed iov_iter") introduced an unnamed
        union inside a struct which gcc-4.4.7 cannot handle.  Name the unnamed
         union as u in order to fix build failure"
      
      Let's do this instead: there is only one place in the entire tree that
      steps into this breakage.  Anon structs and unions work in older gcc
      versions; as the matter of fact, we have those in the tree - see e.g.
      struct ieee80211_tx_info in include/net/mac80211.h
      
      What doesn't work is handling their initializers:
      
      struct {
      	int a;
      	union {
      		int b;
      		char c;
      	};
      } x[2] = {{.a = 1, .c = 'a'}, {.a = 0, .b = 1}};
      
      is the obvious syntax for initializer, perfectly fine for C11 and
      handled correctly by gcc-4.7 or later.
      
      Earlier versions, though, break on it - declaration is fine and so's
      access to fields (i.e.  x[0].c = 'a'; would produce the right code), but
      members of the anon structs and unions are not inserted into the right
      namespace.  Tellingly, those older versions will not barf on struct {int
      a; struct {int a;};}; - looks like they just have it hacked up somewhere
      around the handling of .  and -> instead of doing the right thing.
      
      The easiest way to deal with that crap is to turn initialization of
      those fields (in the only place where we have such initializer of
      iov_iter) into plain assignment.
