      userns: Pass a userns parameter into posix_acl_to_xattr and posix_acl_from_xattr · 5f3a4a28
      Eric W. Biederman 提交于
       - Pass the user namespace the uid and gid values in the xattr are stored
         in into posix_acl_from_xattr.
      
       - Pass the user namespace kuid and kgid values should be converted into
         when storing uid and gid values in an xattr in posix_acl_to_xattr.
      
      - Modify all callers of posix_acl_from_xattr and posix_acl_to_xattr to
        pass in &init_user_ns.
      
      In the short term this change is not strictly needed but it makes the
      code clearer.  In the longer term this change is necessary to be able to
      mount filesystems outside of the initial user namespace that natively
      store posix acls in the linux xattr format.

      security: new security_inode_init_security API adds function callback · 9d8f13ba
      Mimi Zohar 提交于
      This patch changes the security_inode_init_security API by adding a
      filesystem specific callback to write security extended attributes.
      This change is in preparation for supporting the initialization of
      multiple LSM xattrs and the EVM xattr.  Initially the callback function
      walks an array of xattrs, writing each xattr separately, but could be
      optimized to write multiple xattrs at once.
      
      For existing security_inode_init_security() calls, which have not yet
      been converted to use the new callback function, such as those in
      reiserfs and ocfs2, this patch defines security_old_inode_init_security().

      fs/vfs/security: pass last path component to LSM on inode creation · 2a7dba39
      Eric Paris 提交于
      SELinux would like to implement a new labeling behavior of newly created
      inodes.  We currently label new inodes based on the parent and the creating
      process.  This new behavior would also take into account the name of the
      new object when deciding the new label.  This is not the (supposed) full path,
      just the last component of the path.
      
      This is very useful because creating /etc/shadow is different than creating
      /etc/passwd but the kernel hooks are unable to differentiate these
      operations.  We currently require that userspace realize it is doing some
      difficult operation like that and than userspace jumps through SELinux hoops
      to get things set up correctly.  This patch does not implement new
      behavior, that is obviously contained in a seperate SELinux patch, but it
      does pass the needed name down to the correct LSM hook.  If no such name
      exists it is fine to pass NULL.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo 提交于
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      dquot: cleanup space allocation / freeing routines · 5dd4056d
      Christoph Hellwig 提交于
      Get rid of the alloc_space, free_space, reserve_space, claim_space and
      release_rsv dquot operations - they are always called from the filesystem
      and if a filesystem really needs their own (which none currently does)
      it can just call into it's own routine directly.
      
      Move shared logic into the common __dquot_alloc_space,
      dquot_claim_space_nodirty and __dquot_free_space low-level methods,
      and rationalize the wrappers around it to move as much as possible
      code into the common block for CONFIG_QUOTA vs not.  Also rename
      all these helpers to be named dquot_* instead of vfs_dq_*.

      Introduce is_owner_or_cap() to wrap CAP_FOWNER use with fsuid check · 3bd858ab
      Satyam Sharma 提交于
      Introduce is_owner_or_cap() macro in fs.h, and convert over relevant
      users to it. This is done because we want to avoid bugs in the future
      where we check for only effective fsuid of the current task against a
      file's owning uid, without simultaneously checking for CAP_FOWNER as
      well, thus violating its semantics.
      [ XFS uses special macros and structures, and in general looked ...
      untouchable, so we leave it alone -- but it has been looked over. ]
      
      The (current->fsuid != inode->i_uid) check in generic_permission() and
      exec_permission_lite() is left alone, because those operations are
      covered by CAP_DAC_OVERRIDE and CAP_DAC_READ_SEARCH. Similarly operations
      falling under the purview of CAP_CHOWN and CAP_LEASE are also left alone.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
