       "Four patches to fix various problems with the audit subsystem, all are
        fairly small and straightforward.
      
        One patch fixes a problem where we weren't using the correct gfp
        allocation flags (GFP_KERNEL regardless of context, oops), one patch
        fixes a problem with old userspace tools (this was broken for a
        while), one patch fixes a problem where we weren't recording pathnames
        correctly, and one fixes a problem with PID based filters.
      
        In general I don't think there is anything controversial with this
        patchset, and it fixes some rather unfortunate bugs; the allocation
        flag one can be particularly scary looking for users"

      audit: restore AUDIT_LOGINUID unset ABI · 041d7b98
      Richard Guy Briggs 提交于
      A regression was caused by commit 780a7654:
      	 audit: Make testing for a valid loginuid explicit.
      (which in turn attempted to fix a regression caused by e1760bd5)
      
      When audit_krule_to_data() fills in the rules to get a listing, there was a
      missing clause to convert back from AUDIT_LOGINUID_SET to AUDIT_LOGINUID.
      
      This broke userspace by not returning the same information that was sent and
      expected.
      
      The rule:
      	auditctl -a exit,never -F auid=-1
      gives:
      	auditctl -l
      		LIST_RULES: exit,never f24=0 syscall=all
      when it should give:
      		LIST_RULES: exit,never auid=-1 (0xffffffff) syscall=all
      
      Tag it so that it is reported the same way it was set.  Create a new
      private flags audit_krule field (pflags) to store it that won't interact with
      the public one from the API.

      arm64: kernel: fix __cpu_suspend mm switch on warm-boot · f43c2718
      Lorenzo Pieralisi 提交于
      On arm64 the TTBR0_EL1 register is set to either the reserved TTBR0
      page tables on boot or to the active_mm mappings belonging to user space
      processes, it must never be set to swapper_pg_dir page tables mappings.
      
      When a CPU is booted its active_mm is set to init_mm even though its
      TTBR0_EL1 points at the reserved TTBR0 page mappings. This implies
      that when __cpu_suspend is triggered the active_mm can point at
      init_mm even if the current TTBR0_EL1 register contains the reserved
      TTBR0_EL1 mappings.
      
      Therefore, the mm save and restore executed in __cpu_suspend might
      turn out to be erroneous in that, if the current->active_mm corresponds
      to init_mm, on resume from low power it ends up restoring in the
      TTBR0_EL1 the init_mm mappings that are global and can cause speculation
      of TLB entries which end up being propagated to user space.
      
      This patch fixes the issue by checking the active_mm pointer before
      restoring the TTBR0 mappings. If the current active_mm == &init_mm,
      the code sets the TTBR0_EL1 to the reserved TTBR0 mapping instead of
      switching back to the active_mm, which is the expected behaviour
      corresponding to the TTBR0_EL1 settings when __cpu_suspend was entered.

      audit: correctly record file names with different path name types · 4a928436
      Paul Moore 提交于
      There is a problem with the audit system when multiple audit records
      are created for the same path, each with a different path name type.
      The root cause of the problem is in __audit_inode() when an exact
      match (both the path name and path name type) is not found for a
      path name record; the existing code creates a new path name record,
      but it never sets the path name in this record, leaving it NULL.
      This patch corrects this problem by assigning the path name to these
      newly created records.
      
      There are many ways to reproduce this problem, but one of the
      easiest is the following (assuming auditd is running):
      
        # mkdir /root/tmp/test
        # touch /root/tmp/test/567
        # auditctl -a always,exit -F dir=/root/tmp/test
        # touch /root/tmp/test/567
      
      Afterwards, or while the commands above are running, check the audit
      log and pay special attention to the PATH records.  A faulty kernel
      will display something like the following for the file creation:
      
        type=SYSCALL msg=audit(1416957442.025:93): arch=c000003e syscall=2
          success=yes exit=3 ... comm="touch" exe="/usr/bin/touch"
        type=CWD msg=audit(1416957442.025:93):  cwd="/root/tmp"
        type=PATH msg=audit(1416957442.025:93): item=0 name="test/"
          inode=401409 ... nametype=PARENT
        type=PATH msg=audit(1416957442.025:93): item=1 name=(null)
          inode=393804 ... nametype=NORMAL
        type=PATH msg=audit(1416957442.025:93): item=2 name=(null)
          inode=393804 ... nametype=NORMAL
      
      While a patched kernel will show the following:
      
        type=SYSCALL msg=audit(1416955786.566:89): arch=c000003e syscall=2
          success=yes exit=3 ... comm="touch" exe="/usr/bin/touch"
        type=CWD msg=audit(1416955786.566:89):  cwd="/root/tmp"
        type=PATH msg=audit(1416955786.566:89): item=0 name="test/"
          inode=401409 ... nametype=PARENT
        type=PATH msg=audit(1416955786.566:89): item=1 name="test/567"
          inode=393804 ... nametype=NORMAL
      
      This issue was brought up by a number of people, but special credit
      should go to hujianyang@huawei.com for reporting the problem along
      with an explanation of the problem and a patch.  While the original
      patch did have some problems (see the archive link below), it did
      demonstrate the problem and helped kickstart the fix presented here.

        As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com
        ACCESS_ONCE might fail with specific compilers for non-scalar
        accesses.
      
        Here is a set of patches to tackle that problem.
      
        The first patch introduce READ_ONCE and ASSIGN_ONCE.  If the data
        structure is larger than the machine word size memcpy is used and a
        warning is emitted.  The next patches fix up several in-tree users of
        ACCESS_ONCE on non-scalar types.
      
        This does not yet contain a patch that forces ACCESS_ONCE to work only
        on scalar types.  This is targetted for the next merge window as Linux

      audit: don't attempt to lookup PIDs when changing PID filtering audit rules · 3640dcfa
      Paul Moore 提交于
      Commit f1dc4867 ("audit: anchor all pid references in the initial pid
      namespace") introduced a find_vpid() call when adding/removing audit
      rules with PID/PPID filters; unfortunately this is problematic as
      find_vpid() only works if there is a task with the associated PID
      alive on the system.  The following commands demonstrate a simple
      reproducer.
      
      	# auditctl -D
      	# auditctl -l
      	# autrace /bin/true
      	# auditctl -l
      
      This patch resolves the problem by simply using the PID provided by
      the user without any additional validation, e.g. no calls to check to
      see if the task/PID exists.

      CRIS: Export missing function symbols · dbd3c7e1
      Jesper Nilsson 提交于
      strcmp was lost when all other string functions were removed,
      but we still have an optimized version for this on CRISv32,
      so any driver built as a module would not have access to this symbol.
      
      In a similar manner, we had optimized versions of
      csum_partial_copy_from_user and __do_clear_user
      but no exported symbols for them, breaking bunch of other drivers
      when built as a module.
      
      At the same time, move EXPORT_SYMBOL(__copy_user) and
      EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's
      located together with the function definition.
