      Merge tag 'clone3-tls-v5.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux · 606e9ad2
      Linus Torvalds 提交于
      Pull thread fixes from Christian Brauner:
       "This contains a series of patches to fix CLONE_SETTLS when used with
        clone3().
      
        The clone3() syscall passes the tls argument through struct clone_args
        instead of a register. This means, all architectures that do not
        implement copy_thread_tls() but still support CLONE_SETTLS via
        copy_thread() expecting the tls to be located in a register argument
        based on clone() are currently unfortunately broken. Their tls value
        will be garbage.
      
        The patch series fixes this on all architectures that currently define
        __ARCH_WANT_SYS_CLONE3. It also adds a compile-time check to ensure
        that any architecture that enables clone3() in the future is forced to
        also implement copy_thread_tls().
      
        My ultimate goal is to get rid of the copy_thread()/copy_thread_tls()
        split and just have copy_thread_tls() at some point in the not too
        distant future (Maybe even renaming copy_thread_tls() back to simply
        copy_thread() once the old function is ripped from all arches). This
        is dependent now on all arches supporting clone3().
      
        While all relevant arches do that now there are still four missing:
        ia64, m68k, sh and sparc. They have the system call reserved, but not
        implemented. Once they all implement clone3() we can get rid of
        ARCH_WANT_SYS_CLONE3 and HAVE_COPY_THREAD_TLS.
      
        This series also includes a minor fix for the arm64 uapi headers which
        caused __NR_clone3 to be missing from the exported user headers.
      
        Unfortunately the series came in a little late especially given that
        it touches a range of architectures. Due to the holidays not all arch
        maintainers responded in time probably due to their backlog. Will and
        Arnd have thankfully acked the arm specific changes.
      
        Given that the changes are straightforward and rather minimal combined
        with the fact the that clone3() with CLONE_SETTLS is broken I decided
        to send them post rc3 nonetheless"

      fs: move guard_bio_eod() after bio_set_op_attrs · 83c9c547
      Ming Lei 提交于
      Commit 85a8ce62 ("block: add bio_truncate to fix guard_bio_eod")
      adds bio_truncate() for handling bio EOD. However, bio_truncate()
      doesn't use the passed 'op' parameter from guard_bio_eod's callers.
      
      So bio_trunacate() may retrieve wrong 'op', and zering pages may
      not be done for READ bio.
      
      Fixes this issue by moving guard_bio_eod() after bio_set_op_attrs()
      in submit_bh_wbc() so that bio_truncate() can always retrieve correct
      op info.
      
      Meantime remove the 'op' parameter from guard_bio_eod() because it isn't
      used any more.

      pstore/ram: Regularize prz label allocation lifetime · e163fdb3
      Kees Cook 提交于
      In my attempt to fix a memory leak, I introduced a double-free in the
      pstore error path. Instead of trying to manage the allocation lifetime
      between persistent_ram_new() and its callers, adjust the logic so
      persistent_ram_new() always takes a kstrdup() copy, and leaves the
      caller's allocation lifetime up to the caller. Therefore callers are
      _always_ responsible for freeing their label. Before, it only needed
      freeing when the prz itself failed to allocate, and not in any of the
      other prz failure cases, which callers would have no visibility into,
      which is the root design problem that lead to both the leak and now
      double-free bugs.

      tipc: fix wrong connect() return code · 9546a0b7
      Tuong Lien 提交于
      The current 'tipc_wait_for_connect()' function does a wait-loop for the
      condition 'sk->sk_state != TIPC_CONNECTING' to conclude if the socket
      connecting has done. However, when the condition is met, it returns '0'
      even in the case the connecting is actually failed, the socket state is
      set to 'TIPC_DISCONNECTING' (e.g. when the server socket has closed..).
      This results in a wrong return code for the 'connect()' call from user,
      making it believe that the connection is established and go ahead with
      building, sending a message, etc. but finally failed e.g. '-EPIPE'.
      
      This commit fixes the issue by changing the wait condition to the
      'tipc_sk_connected(sk)', so the function will return '0' only when the
      connection is really established. Otherwise, either the socket 'sk_err'
      if any or '-ETIMEDOUT'/'-EINTR' will be returned correspondingly.

      tipc: fix link overflow issue at socket shutdown · 49afb806
      Tuong Lien 提交于
      When a socket is suddenly shutdown or released, it will reject all the
      unreceived messages in its receive queue. This applies to a connected
      socket too, whereas there is only one 'FIN' message required to be sent
      back to its peer in this case.
      
      In case there are many messages in the queue and/or some connections
      with such messages are shutdown at the same time, the link layer will
      easily get overflowed at the 'TIPC_SYSTEM_IMPORTANCE' backlog level
      because of the message rejections. As a result, the link will be taken
      down. Moreover, immediately when the link is re-established, the socket
      layer can continue to reject the messages and the same issue happens...
      
      The commit refactors the '__tipc_shutdown()' function to only send one
      'FIN' in the situation mentioned above. For the connectionless case, it
      is unavoidable but usually there is no rejections for such socket
      messages because they are 'dest-droppable' by default.
      
      In addition, the new code makes the other socket states clear
      (e.g.'TIPC_LISTEN') and treats as a separate case to avoid misbehaving.
