      Revert "selftests: net: Add tls config dependency for tls selftests" · 20695e9a
      Jakub Kicinski authored
      This reverts commit d9142e1c.
      
      The test is supposed to run cleanly with TLS is disabled,
      to test compatibility with TCP behavior. I can't repro
      the failure [1], the problem should be debugged rather
      than papered over.

      net/smc: Send out the remaining data in sndbuf before close · 906b3d64
      Wen Gu authored
      The current autocork algorithms will delay the data transmission
      in BH context to smc_release_cb() when sock_lock is hold by user.
      
      So there is a possibility that when connection is being actively
      closed (sock_lock is hold by user now), some corked data still
      remains in sndbuf, waiting to be sent by smc_release_cb(). This
      will cause:
      
      - smc_close_stream_wait(), which is called under the sock_lock,
        has a high probability of timeout because data transmission is
        delayed until sock_lock is released.
      
      - Unexpected data sends may happen after connction closed and use
        the rtoken which has been deleted by remote peer through
        LLC_DELETE_RKEY messages.
      
      So this patch will try to send out the remaining corked data in
      sndbuf before active close process, to ensure data integrity and
      avoid unexpected data transmission after close.

      There's no reason for this to be in netdevice.h, it's all
      just used in dev.c. Also make it no longer inline and let
      the compiler decide to do that by itself.

      net: dsa: bcm_sf2_cfp: fix an incorrect NULL check on list iterator · 6da69b1d
      Xiaomeng Tong authored
      The bug is here:
      	return rule;
      
      The list iterator value 'rule' will *always* be set and non-NULL
      by list_for_each_entry(), so it is incorrect to assume that the
      iterator value will be NULL if the list is empty or no element
      is found.
      
      To fix the bug, return 'rule' when found, otherwise return NULL.

      cc1: all warnings being treated as errors
      
      This is due to the function ptp_find_pin() returning a pin ID of -1 when
      a valid pin is not found and this error never being checked.
      Change the TSIO_PIN_VALID() function to also check that a pin ID is not
      negative and use this macro in bnxt_ptp_enable() to check the result of
      the calls to ptp_find_pin() to return an error early for invalid pins.
      This fixes the compilation error.

      Reinstate some of "swiotlb: rework "fix info leak with DMA_FROM_DEVICE"" · 901c7280
      Linus Torvalds authored
      Halil Pasic points out [1] that the full revert of that commit (revert
      in bddac7c1), and that a partial revert that only reverts the
      problematic case, but still keeps some of the cleanups is probably
      better.  
      
      And that partial revert [2] had already been verified by Oleksandr
      Natalenko to also fix the issue, I had just missed that in the long
      discussion.
      
      So let's reinstate the cleanups from commit aa6f8dcb ("swiotlb:
      rework "fix info leak with DMA_FROM_DEVICE""), and effectively only
      revert the part that caused problems.

      memcg: enable accounting for nft objects · 33758c89
      Vasily Averin authored
      nftables replaces iptables, but it lacks memcg accounting.
      
      This patch account most of the memory allocation associated with nft
      and should protect the host from misusing nft inside a memcg restricted
      container.

      mm: kfence: fix missing objcg housekeeping for SLAB · ae085d7f
      Muchun Song authored
      The objcg is not cleared and put for kfence object when it is freed,
      which could lead to memory leak for struct obj_cgroup and wrong
      statistics of NR_SLAB_RECLAIMABLE_B or NR_SLAB_UNRECLAIMABLE_B.
      
      Since the last freed object's objcg is not cleared,
      mem_cgroup_from_obj() could return the wrong memcg when this kfence
      object, which is not charged to any objcgs, is reallocated to other
      users.
      
      A real word issue [1] is caused by this bug.
