      fs: call security_d_instantiate in d_obtain_alias V2 · 24ff6663
      Josef Bacik authored
      While trying to track down some NFS problems with BTRFS, I kept noticing I was
      getting -EACCESS for no apparent reason.  Eric Paris and printk() helped me
      figure out that it was SELinux that was giving me grief, with the following
      denial
      
      type=AVC msg=audit(1290013638.413:95): avc:  denied  { 0x800000 } for  pid=1772
      comm="nfsd" name="" dev=sda1 ino=256 scontext=system_u:system_r:kernel_t:s0
      tcontext=system_u:object_r:unlabeled_t:s0 tclass=file
      
      Turns out this is because in d_obtain_alias if we can't find an alias we create
      one and do all the normal instantiation stuff, but we don't do the
      security_d_instantiate.
      
      Usually we are protected from getting a hashed dentry that hasn't yet run
      security_d_instantiate() by the parent's i_mutex, but obviously this isn't an
      option there, so in order to deal with the case that a second thread comes in
      and finds our new dentry before we get to run security_d_instantiate(), we go
      ahead and call it if we find a dentry already.  Eric assures me that this is ok
      as the code checks to see if the dentry has been initialized already so calling
      security_d_instantiate() against the same dentry multiple times is ok.  With
      this patch I'm no longer getting errant -EACCESS values.

      change the locking order for namespace_sem · b12cea91
      Al Viro authored
      Have it nested inside ->i_mutex.  Instead of using follow_down()
      under namespace_sem, followed by grabbing i_mutex and checking that
      mountpoint to be is not dead, do the following:
      	grab i_mutex
      	check that it's not dead
      	grab namespace_sem
      	see if anything is mounted there
      	if not, we've won
      	otherwise
      		drop locks
      		put_path on what we had
      		replace with what's mounted
      		retry everything with new mountpoint to be
      
      New helper (lock_mount()) does that.  do_add_mount(), do_move_mount(),
      do_loopback() and pivot_root() switched to it; in case of the last
      two that eliminates a race we used to have - original code didn't
      do follow_down().

      Don't hold vfsmount_lock over the loop traversing ->mnt_parent;
      do check_mnt(new.mnt) under namespace_sem instead; combined with

      x86: Flush TLB if PGD entry is changed in i386 PAE mode · 4981d01e
      Shaohua Li authored
      According to intel CPU manual, every time PGD entry is changed in i386 PAE
      mode, we need do a full TLB flush. Current code follows this and there is
      comment for this too in the code.
      
      But current code misses the multi-threaded case. A changed page table
      might be used by several CPUs, every such CPU should flush TLB. Usually
      this isn't a problem, because we prepopulate all PGD entries at process
      fork. But when the process does munmap and follows new mmap, this issue
      will be triggered.
      
      When it happens, some CPUs keep doing page faults:

      x86, dumpstack: Correct stack dump info when frame pointer is available · e8e999cf
      Namhyung Kim authored
      Current stack dump code scans entire stack and check each entry
      contains a pointer to kernel code. If CONFIG_FRAME_POINTER=y it
      could mark whether the pointer is valid or not based on value of
      the frame pointer. Invalid entries could be preceded by '?' sign.
      
      However this was not going to happen because scan start point
      was always higher than the frame pointer so that they could not
      meet.
      
      Commit 9c0729dc ("x86: Eliminate bp argument from the stack
      tracing routines") delayed bp acquisition point, so the bp was
      read in lower frame, thus all of the entries were marked
      invalid.
      
      This patch fixes this by reverting above commit while retaining
      stack_frame() helper as suggested by Frederic Weisbecker.
      
      End result looks like below:

      The user-supplied index into the adapters array needs to be checked, or

      new function: mount_fs().  Does all work done by vfs_kern_mount()
      except the allocation and filling of vfsmount; returns root dentry
      or ERR_PTR().
      
      vfs_kern_mount() switched to using it and taken to fs/namespace.c,
      along with its wrappers.
      
      alloc_vfsmnt()/free_vfsmnt() made static.
