      compat: fs: Generic compat_sys_sendfile implementation · 8f9c0119
      Catalin Marinas 提交于
      This function is used by sparc, powerpc and arm64 for compat support.
      The patch adds a generic implementation which calls do_sendfile()
      directly and avoids set_fs().
      
      The sparc architecture has wrappers for the sign extensions while
      powerpc relies on the compiler to do the this. The patch adds wrappers
      for powerpc to handle the u32->int type conversion.
      
      compat_sys_sendfile64() can be replaced by a sys_sendfile() call since
      compat_loff_t has the same size as off_t on a 64-bit system.
      
      On powerpc, the patch also changes the 64-bit sendfile call from
      sys_sendile64 to sys_sendfile.

      Cross Memory Attach · fcf63409
      Christopher Yeoh 提交于
      The basic idea behind cross memory attach is to allow MPI programs doing
      intra-node communication to do a single copy of the message rather than a
      double copy of the message via shared memory.
      
      The following patch attempts to achieve this by allowing a destination
      process, given an address and size from a source process, to copy memory
      directly from the source process into its own address space via a system
      call.  There is also a symmetrical ability to copy from the current
      process's address space into a destination process's address space.
      
      - Use of /proc/pid/mem has been considered, but there are issues with
        using it:
        - Does not allow for specifying iovecs for both src and dest, assuming
          preadv or pwritev was implemented either the area read from or
        written to would need to be contiguous.
        - Currently mem_read allows only processes who are currently
        ptrace'ing the target and are still able to ptrace the target to read
        from the target. This check could possibly be moved to the open call,
        but its not clear exactly what race this restriction is stopping
        (reason  appears to have been lost)
        - Having to send the fd of /proc/self/mem via SCM_RIGHTS on unix
        domain socket is a bit ugly from a userspace point of view,
        especially when you may have hundreds if not (eventually) thousands
        of processes  that all need to do this with each other
        - Doesn't allow for some future use of the interface we would like to
        consider adding in the future (see below)
        - Interestingly reading from /proc/pid/mem currently actually
        involves two copies! (But this could be fixed pretty easily)
      
      As mentioned previously use of vmsplice instead was considered, but has
      problems.  Since you need the reader and writer working co-operatively if
      the pipe is not drained then you block.  Which requires some wrapping to
      do non blocking on the send side or polling on the receive.  In all to all
      communication it requires ordering otherwise you can deadlock.  And in the
      example of many MPI tasks writing to one MPI task vmsplice serialises the
      copying.
      
      There are some cases of MPI collectives where even a single copy interface
      does not get us the performance gain we could.  For example in an
      MPI_Reduce rather than copy the data from the source we would like to
      instead use it directly in a mathops (say the reduce is doing a sum) as
      this would save us doing a copy.  We don't need to keep a copy of the data
      from the source.  I haven't implemented this, but I think this interface
      could in the future do all this through the use of the flags - eg could
      specify the math operation and type and the kernel rather than just
      copying the data would apply the specified operation between the source
      and destination and store it in the destination.
      
      Although we don't have a "second user" of the interface (though I've had
      some nibbles from people who may be interested in using it for intra
      process messaging which is not MPI).  This interface is something which
      hardware vendors are already doing for their custom drivers to implement
      fast local communication.  And so in addition to this being useful for
      OpenMPI it would mean the driver maintainers don't have to fix things up
      when the mm changes.
      
      There was some discussion about how much faster a true zero copy would
      go. Here's a link back to the email with some testing I did on that:
      
      http://marc.info/?l=linux-mm&m=130105930902915&w=2
      
      There is a basic man page for the proposed interface here:
      
      http://ozlabs.org/~cyeoh/cma/process_vm_readv.txt
      
      This has been implemented for x86 and powerpc, other architecture should
      mainly (I think) just need to add syscall numbers for the process_vm_readv
      and process_vm_writev. There are 32 bit compatibility versions for
      64-bit kernels.
      
      For arch maintainers there are some simple tests to be able to quickly
      verify that the syscalls are working correctly here:

      ns: Wire up the setns system call · 7b21fddd
      Eric W. Biederman 提交于
      32bit and 64bit on x86 are tested and working.  The rest I have looked
      at closely and I can't find any problems.
      
      setns is an easy system call to wire up.  It just takes two ints so I
      don't expect any weird architecture porting problems.
      
      While doing this I have noticed that we have some architectures that are
      very slow to get new system calls.  cris seems to be the slowest where
      the last system calls wired up were preadv and pwritev.  avr32 is weird
      in that recvmmsg was wired up but never declared in unistd.h.  frv is
      behind with perf_event_open being the last syscall wired up.  On h8300
      the last system call wired up was epoll_wait.  On m32r the last system
      call wired up was fallocate.  mn10300 has recvmmsg as the last system
      call wired up.  The rest seem to at least have syncfs wired up which was
      new in the 2.6.39.
      
      v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com>
      v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com>
      v4: Moved wiring up of the system call to another patch
      v5: ported to v2.6.39-rc6
      v6: rebased onto parisc-next and net-next to avoid syscall  conflicts.
      v7: ported to Linus's latest post 2.6.39 tree.

      net: Add sendmmsg socket system call · 228e548e

      This patch adds a multiple message send syscall and is the send
      version of the existing recvmmsg syscall. This is heavily
      based on the patch by Arnaldo that added recvmmsg.

      this new syscall:

      perf: Do the big rename: Performance Counters -> Performance Events · cdd6c482
      Ingo Molnar 提交于
      Bye-bye Performance Counters, welcome Performance Events!
      
      In the past few months the perfcounters subsystem has grown out its
      initial role of counting hardware events, and has become (and is
      becoming) a much broader generic event enumeration, reporting, logging,
      monitoring, analysis facility.
      
      Naming its core object 'perf_counter' and naming the subsystem
      'perfcounters' has become more and more of a misnomer. With pending
      code like hw-breakpoints support the 'counter' name is less and
      less appropriate.
      
      All in one, we've decided to rename the subsystem to 'performance
      events' and to propagate this rename through all fields, variables
      and API names. (in an ABI compatible fashion)
      
      The word 'event' is also a bit shorter than 'counter' - which makes
      it slightly more convenient to write/handle as well.
      
      Thanks goes to Stephane Eranian who first observed this misnomer and
      suggested a rename.
      
      User-space tooling and ABI compatibility is not affected - this patch
      should be function-invariant. (Also, defconfigs were not touched to
      keep the size down.)
      
      This patch has been generated via the following script:
      
        FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')
      
        sed -i \
          -e 's/PERF_EVENT_/PERF_RECORD_/g' \
          -e 's/PERF_COUNTER/PERF_EVENT/g' \
          -e 's/perf_counter/perf_event/g' \
          -e 's/nb_counters/nb_events/g' \
          -e 's/swcounter/swevent/g' \
          -e 's/tpcounter_event/tp_event/g' \
          $FILES
      
        for N in $(find . -name perf_counter.[ch]); do
          M=$(echo $N | sed 's/perf_counter/perf_event/g')
          mv $N $M
        done
      
        FILES=$(find . -name perf_event.*)
      
        sed -i \
          -e 's/COUNTER_MASK/REG_MASK/g' \
          -e 's/COUNTER/EVENT/g' \
          -e 's/\<event\>/event_id/g' \
          -e 's/counter/event/g' \
          -e 's/Counter/Event/g' \
          $FILES
      
      ... to keep it as correct as possible. This script can also be
      used by anyone who has pending perfcounters patches - it converts
      a Linux kernel tree over to the new naming. We tried to time this
      change to the point in time where the amount of pending patches
      is the smallest: the end of the merge window.
      
      Namespace clashes were fixed up in a preparatory patch - and some
      stylistic fallout will be fixed up in a subsequent patch.
      
      ( NOTE: 'counters' are still the proper terminology when we deal
        with hardware registers - and these sed scripts are a bit
        over-eager in renaming them. I've undone some of that, but
        in case there's something left where 'counter' would be
        better than 'event' we can undo that on an individual basis
        instead of touching an otherwise nicely automated patch. )

      generic compat_sys_ustat · 2b1c6bd7
      Christoph Hellwig 提交于
      Due to a different size of ino_t ustat needs a compat handler, but
      currently only x86 and mips provide one.  Add a generic compat_sys_ustat
      and switch all architectures over to it.  Instead of doing various
      user copy hacks compat_sys_ustat just reimplements sys_ustat as
      it's trivial.  This was suggested by Arnd Bergmann.
      
      Found by Eric Sandeen when running xfstests/017 on ppc64, which causes

      perfcounters: fix a few minor cleanliness issues · f3dfd265
      Paul Mackerras 提交于
      This fixes three issues noticed by Arnd Bergmann:
      
      - Add #ifdef __KERNEL__ and move some things around in perf_counter.h
        to make sure only the bits that userspace needs are exported to
        userspace.
      
      - Use __u64, __s64, __u32 types in the structs exported to userspace
        rather than u64, s64, u32.
      
      - Make the sys_perf_counter_open syscall available to the SPUs on
        Cell platforms.
      
      And one issue that I noticed in looking at the code again:
      
      - Wrap the perf_counter_open syscall with SYSCALL_DEFINE4 so we get
        the proper handling of int arguments on ppc64 (and some other 64-bit
        architectures).

      timerfd: new timerfd API · 4d672e7a
      Davide Libenzi 提交于
      This is the new timerfd API as it is implemented by the following patch:
      
      int timerfd_create(int clockid, int flags);
      int timerfd_settime(int ufd, int flags,
      		    const struct itimerspec *utmr,
      		    struct itimerspec *otmr);
      int timerfd_gettime(int ufd, struct itimerspec *otmr);
      
      The timerfd_create() API creates an un-programmed timerfd fd.  The "clockid"
      parameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME.
      
      The timerfd_settime() API give new settings by the timerfd fd, by optionally
      retrieving the previous expiration time (in case the "otmr" parameter is not
      NULL).
      
      The time value specified in "utmr" is absolute, if the TFD_TIMER_ABSTIME bit
      is set in the "flags" parameter.  Otherwise it's a relative time.
      
      The timerfd_gettime() API returns the next expiration time of the timer, or
      {0, 0} if the timerfd has not been set yet.
      
      Like the previous timerfd API implementation, read(2) and poll(2) are
      supported (with the same interface).  Here's a simple test program I used to
      exercise the new timerfd APIs:

      [POWERPC] Provide a way to protect 4k subpages when using 64k pages · fa28237c
      Paul Mackerras 提交于
      Using 64k pages on 64-bit PowerPC systems makes life difficult for
      emulators that are trying to emulate an ISA, such as x86, which use a
      smaller page size, since the emulator can no longer use the MMU and
      the normal system calls for controlling page protections.  Of course,
      the emulator can emulate the MMU by checking and possibly remapping
      the address for each memory access in software, but that is pretty
      slow.
      
      This provides a facility for such programs to control the access
      permissions on individual 4k sub-pages of 64k pages.  The idea is
      that the emulator supplies an array of protection masks to apply to a
      specified range of virtual addresses.  These masks are applied at the
      level where hardware PTEs are inserted into the hardware page table
      based on the Linux PTEs, so the Linux PTEs are not affected.  Note
      that this new mechanism does not allow any access that would otherwise
      be prohibited; it can only prohibit accesses that would otherwise be
      allowed.  This new facility is only available on 64-bit PowerPC and
      only when the kernel is configured for 64k pages.
      
      The masks are supplied using a new subpage_prot system call, which
      takes a starting virtual address and length, and a pointer to an array
      of protection masks in memory.  The array has a 32-bit word per 64k
      page to be protected; each 32-bit word consists of 16 2-bit fields,
      for which 0 allows any access (that is otherwise allowed), 1 prevents
      write accesses, and 2 or 3 prevent any access.
      
      Implicit in this is that the regions of the address space that are
      protected are switched to use 4k hardware pages rather than 64k
      hardware pages (on machines with hardware 64k page support).  In fact
      the whole process is switched to use 4k hardware pages when the
      subpage_prot system call is used, but this could be improved in future
      to switch only the affected segments.
      
      The subpage protection bits are stored in a 3 level tree akin to the
      page table tree.  The top level of this tree is stored in a structure
      that is appended to the top level of the page table tree, i.e., the
      pgd array.  Since it will often only be 32-bit addresses (below 4GB)
      that are protected, the pointers to the first four bottom level pages
      are also stored in this structure (each bottom level page contains the
      protection bits for 1GB of address space), so the protection bits for
      addresses below 4GB can be accessed with one fewer loads than those
      for higher addresses.

      sys_fallocate() implementation on i386, x86_64 and powerpc · 97ac7350
      Amit Arora 提交于
      fallocate() is a new system call being proposed here which will allow
      applications to preallocate space to any file(s) in a file system.
      Each file system implementation that wants to use this feature will need
      to support an inode operation called ->fallocate().
      Applications can use this feature to avoid fragmentation to certain
      level and thus get faster access speed. With preallocation, applications
      also get a guarantee of space for particular file(s) - even if later the
      the system becomes full.
      
      Currently, glibc provides an interface called posix_fallocate() which
      can be used for similar cause. Though this has the advantage of working
      on all file systems, but it is quite slow (since it writes zeroes to
      each block that has to be preallocated). Without a doubt, file systems
      can do this more efficiently within the kernel, by implementing
      the proposed fallocate() system call. It is expected that
      posix_fallocate() will be modified to call this new system call first
      and incase the kernel/filesystem does not implement it, it should fall
      back to the current implementation of writing zeroes to the new blocks.
      ToDos:
      1. Implementation on other architectures (other than i386, x86_64,
         and ppc). Patches for s390(x) and ia64 are already available from
         previous posts, but it was decided that they should be added later
         once fallocate is in the mainline. Hence not including those patches
         in this take.
      2. Changes to glibc,
         a) to support fallocate() system call
         b) to make posix_fallocate() and posix_fallocate64() call fallocate()

      Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARM · edd5cd4a
      David Woodhouse 提交于
      Not all the world is an i386.  Many architectures need 64-bit arguments to be
      aligned in suitable pairs of registers, and the original
      sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an
      argument register for padding after the first integer.  Since we don't
      normally have more than 6 arguments for system calls, that left no room for
      the final argument on some architectures.
      
      Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which
      all fits nicely.  In fact, ARM already had that, but called it
      sys_arm_sync_file_range.  Move it to fs/sync.c and rename it, then implement
      the needed compatibility routine.  And stop the missing syscall check from
      bitching about the absence of sys_sync_file_range() if we've implemented
      sys_sync_file_range2() instead.
      
      Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.
