Making them\navailable on other architectures is straightforward.\n\nSince no \"user\" for these new parameters is introduced in this patch,\nthe implementation of the new system calls is just identical to their\nalready existing counterpart. Future patches that implement scheduling\npolicies able to exploit the new data structure must also take care of\nmodifying the sched_*attr() calls accordingly with their own purposes.\n\nSigned-off-by: Dario Faggioli \u003craistlin@linux.it\u003e\n[ Rewrote to use sched_attr. ]\nSigned-off-by: Juri Lelli \u003cjuri.lelli@gmail.com\u003e\n[ Removed sched_setscheduler2() for now. ]\nSigned-off-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/1383831828-15501-3-git-send-email-juri.lelli@gmail.com\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n" }, { "commit": "b29c8306a368cf65782669eba079f81dc861c54d", "tree": "35d75aa0e671070d4024f11338d3ae89b078b1ed", "parents": [ "0bde7294e2ada03d0f1cc61cec51274081d9a9cf", "3a81a5210b7d33bb6d836b4c4952a54166a336f3" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Nov 16 12:23:18 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Nov 16 12:23:18 2013 -0800" }, "message": "Merge tag \u0027trace-3.13\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace\n\nPull tracing update from Steven Rostedt:\n \"This batch of changes is mostly clean ups and small bug fixes.

Since the init_module syscall hands the kernel a module\nas a memory blob, no reasoning about the origin of the blob can be made.\n\nEarlier proposals for appending signatures to kernel modules would not be\nuseful in Chrome OS, since it would involve adding an additional set of\nkeys to our kernel and builds for no good reason: we already trust the\ncontents of our root filesystem. We don\u0027t need to verify those kernel\nmodules a second time. Having to do signature checking on module loading\nwould slow us down and be redundant. All we need to know is where a\nmodule is coming from so we can say yes/no to loading it.\n\nIf a file descriptor is used as the source of a kernel module, many more\nthings can be reasoned about. In Chrome OS\u0027s case, we could enforce that\nthe module lives on the filesystem we expect it to live on. In the case\nof IMA (or other LSMs), it would be possible, for example, to examine\nextended attributes that may contain signatures over the contents of\nthe module.\n\nThis introduces a new syscall (on x86), similar to init_module, that has\nonly two arguments.

doing\nintra-node communication to do a single copy of the message rather than a\ndouble copy of the message via shared memory.\n\nThe following patch attempts to achieve this by allowing a destination\nprocess, given an address and size from a source process, to copy memory\ndirectly from the source process into its own address space via a system\ncall. There is also a symmetrical ability to copy from the current\nprocess\u0027s address space into a destination process\u0027s address space.\n\n- Use of /proc/pid/mem has been considered, but there are issues with\n using it:\n - Does not allow for specifying iovecs for both src and dest, assuming\n preadv or pwritev was implemented either the area read from or\n written to would need to be contiguous.\n - Currently mem_read allows only processes who are currently\n ptrace\u0027ing the target and are still able to ptrace the target to read\n from the target. This check could possibly be moved to the open call,\n but its not clear exactly what race this restriction is stopping\n (reason appears to have been lost)\n - Having to send the fd of /proc/self/mem via SCM_RIGHTS on unix\n domain socket is a bit ugly from a userspace point of view,\n especially when you may have hundreds if not (eventually) thousands\n of processes that all need to do this with each other\n - Doesn\u0027t allow for some future use of the interface we would like to\n consider adding in the future (see below)\n - Interestingly reading from /proc/pid/mem currently actually\n involves two copies! (But this could be fixed pretty easily)\n\nAs mentioned previously use of vmsplice instead was considered, but has\nproblems. Since you need the reader and writer working co-operatively if\nthe pipe is not drained then you block. Which requires some wrapping to\ndo non blocking on the send side or polling on the receive. In all to all\ncommunication it requires ordering otherwise you can deadlock. And in the\nexample of many MPI tasks writing to one MPI task vmsplice serialises the\ncopying.\n\nThere are some cases of MPI collectives where even a single copy interface\ndoes not get us the performance gain we could. For example in an\nMPI_Reduce rather than copy the data from the source we would like to\ninstead use it directly in a mathops (say the reduce is doing a sum) as\nthis would save us doing a copy. We don\u0027t need to keep a copy of the data\nfrom the source. I haven\u0027t implemented this, but I think this interface\ncould in the future do all this through the use of the flags - eg could\nspecify the math operation and type and the kernel rather than just\ncopying the data would apply the specified operation between the source\nand destination and store it in the destination.\n\nAlthough we don\u0027t have a \"second user\" of the interface (though I\u0027ve had\nsome nibbles from people who may be interested in using it for intra\nprocess messaging which is not MPI). This interface is something which\nhardware vendors are already doing for their custom drivers to implement\nfast local communication. And so in addition to this being useful for\nOpenMPI it would mean the driver maintainers don\u0027t have to fix things up\nwhen the mm changes.\n\nThere was some discussion about how much faster a true zero copy would\ngo. Here\u0027s a link back to the email with some testing I did on that:\n\nhttp://marc.info/?l\u003dlinux-mm\u0026m\u003d130105930902915\u0026w\u003d2\n\nThere is a basic man page for the proposed interface here:\n\nhttp://ozlabs.org/~cyeoh/cma/process_vm_readv.txt\n\nThis has been implemented for x86 and powerpc, other architecture should\nmainly (I think) just need to add syscall numbers for the process_vm_readv\nand process_vm_writev. There are 32 bit compatibility versions for\n64-bit kernels.\n\nFor arch maintainers there are some simple tests to be able to quickly\nverify that the syscalls are working correctly here:\n\nhttp://ozlabs.org/~cyeoh/cma/cma-test-20110718.tgz\n\nSigned-off-by: Chris Yeoh \u003cyeohc@au1.ibm.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \"H.

Calling fsync(2) on each\n file introduces unnecessary ordering constraints that result in a large\n amount of sub-optimal writeback/flush/commit behavior by the file\n system.\n\nThere are currently two ways (that I know of) to sync a single super_block:\n\n - BLKFLSBUF ioctl on the block device: That also invalidates the bdev\n mapping, which isn\u0027t usually desirable, and doesn\u0027t work for non-block\n file systems.\n - \u0027mount -o remount,rw\u0027 will call sync_filesystem as an artifact of the\n current implemention.

Except for\ns390 and sparc64 all implementations of the sys_ipc are nearly identical.\n\nThere are slight differences in the types of the parameters, where mips\nand powerpc as the only 64-bit architectures with sys_ipc use unsigned\nlong for the \"third\" argument as it gets casted to a pointer later, while\nit traditionally is an \"int\" like most other paramters. frv goes even\nfurther and uses unsigned long for all parameters execept for \"ptr\" which\nis a pointer type everywhere. The change from int to unsigned long for\n\"third\" and back to \"int\" for the others on frv should be fine due to the\nin-register calling conventions for syscalls (we already had a similar\nissue with the generic sys_ptrace), but I\u0027d prefer to have the arch\nmaintainers looks over this in details.\n\nExcept for that h8300, m68k and m68knommu lack an impplementation of the\nsemtimedop sub call which this patch adds, and various architectures have\ngets used - at least on i386 it seems superflous as the compat code on\nx86-64 and ia64 doesn\u0027t even bother to implement it.\n\n[akpm@linux-foundation.org: add sys_ipc to sys_ni.c]\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nReviewed-by: H.
