This means that if the receiver can\u0027t\nkeep up with the rate of flow, then we will hit OOM. Of course\nit gets worse if the OOM killer then decides to kill the receiver.\n\nThis patch imposes a cap on the packet queue length, in the same\nway as the tuntap driver, using the device TX queue length.\n\nPlease note that macvtap currently has no way of giving congestion\nnotification, that means the software device TX queue cannot be\nused and packets will always be dropped once the macvtap driver\nqueue fills up.\n\nThis shouldn\u0027t be a great problem for the scenario where macvtap\nis used to feed a kvm receiver, as the traffic is most likely\nexternal in origin so congestion notification can\u0027t be applied\nanyway.\n\nOf course, if anybody decides to complain about guest-to-guest\nUDP packet loss down the track, then we may have to revisit this.\n\nIncidentally, this patch also fixes a real memory leak when\nmacvtap_get_queue fails.\n\nChris Wright noticed that for this patch to work, we need a\nnon-zero TX queue length.

"fs: introduce new truncate sequence\n\nIntroduce a new truncate calling sequence into fs/mm subsystems. Rather than\nsetattr \u003e vmtruncate \u003e truncate, have filesystems call their truncate sequence\nfrom -\u003esetattr if filesystem specific operations are required. vmtruncate is\ndeprecated, and truncate_pagecache and inode_newsize_ok helpers introduced\npreviously should be used.\n\nsimple_setattr is introduced for simple in-ram filesystems to implement\nthe new truncate sequence. Eventually all filesystems should be converted\nto implement a setattr, and the default code in notify_change should go\naway.\n\nsimple_setsize is also introduced to perform just the ATTR_SIZE portion\nof simple_setattr (ie. changing i_size and trimming pagecache).\n\nTo implement the new truncate sequence:\n- filesystem specific manipulations (eg freeing blocks) must be done in\n the setattr method rather than -\u003etruncate.\n- vmtruncate can not be used by core code to trim blocks past i_size in\n the event of write failure after allocation, so this must be performed\n in the fs code.\n- convert usage of helpers block_write_begin, nobh_write_begin,\n cont_write_begin, and *blockdev_direct_IO* to use _newtrunc postfixed\n variants. These avoid calling vmtruncate to trim blocks (see previous).\n- inode_setattr should not be used. generic_setattr is a new function\n to be used to copy simple attributes into the generic inode.\n- make use of the better opportunity to handle errors with the new sequence.\n\nBig problem with the previous calling sequence: the filesystem is not called\nuntil i_size has already changed. This means it is not allowed to fail the\ncall, and also it does not know what the previous i_size was. Also, generic\ncode calling vmtruncate to truncate allocated blocks in case of error had\nno good way to return a meaningful error (or, for example, atomically handle\nblock deallocation).\n\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nAcked-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "1b061d9247f71cd15edc4c4c4600191a903642c0", "tree": "30d92ca82d8286e7a45fba108230ecd23e61673b", "parents": [ "7ea8085910ef3dd4f3cad6845aaa2b580d39b115" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Wed May 26 17:53:41 2010 +0200" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Thu May 27 22:06:06 2010 -0400" }, "message": "rename the generic fsync implementations\n\nWe don\u0027t name our generic fsync implementations very well currently.\nThe no-op implementation for in-memory filesystems currently is called\nsimple_sync_file which doesn\u0027t make too much sense to start with,\nthe the generic one for simple filesystems is called simple_fsync\nwhich can lead to some confusion.\n\nThis patch renames the generic file fsync method to generic_file_fsync\nto match the other generic_file_* routines it is supposed to be used\nwith, and the no-op implementation to noop_fsync to make it obvious\nwhat to expect.

We had reports of several races, including\nsome reports of apps bypassing our recursion check so that a process that\nwas forked as part of a core_pattern setup could infinitely crash and\nrefork until the system crashed.\n\nWe fixed those by improving our recursion checks. The new check basically\nrefuses to fork a process if its core limit is zero, which works well.\n\nUnfortunately, I\u0027ve been getting grief from maintainer of user space\nprograms that are inserted as the forked process of core_pattern. They\ncontend that in order for their programs (such as abrt and apport) to\nwork, all the running processes in a system must have their core limits\nset to a non-zero value, to which I say \u0027yes\u0027. I did this by design, and\nthink thats the right way to do things.\n\nBut I\u0027ve been asked to ease this burden on user space enough times that I\nthought I would take a look at it. The first suggestion was to make the\nrecursion check fail on a non-zero \u0027special\u0027 number, like one. That way\nthe core collector process could set its core size ulimit to 1, and enable\nthe kernel\u0027s recursion detection. This isn\u0027t a bad idea on the surface,\nbut I don\u0027t like it since its opt-in, in that if a program like abrt or\napport has a bug and fails to set such a core limit, we\u0027re left with a\nrecursively crashing system again.\n\nSo I\u0027ve come up with this. What I\u0027ve done is modify the\ncall_usermodehelper api such that an extra parameter is added, a function\npointer which will be called by the user helper task, after it forks, but\nbefore it exec\u0027s the required process. This will give the caller the\nopportunity to get a call back in the processes context, allowing it to do\nwhatever it needs to to the process in the kernel prior to exec-ing the\nuser space code. In the case of do_coredump, this callback is ues to set\nthe core ulimit of the helper process to 1. This elimnates the opt-in\nproblem that I had above, as it allows the ulimit for core sizes to be set\nto the value of 1, which is what the recursion check looks for in\ndo_coredump.\n\nThis patch:\n\nCreate new function call_usermodehelper_fns() and allow it to assign both\nan init and cleanup function, as we\u0027ll as arbitrary data.\n\nThe init function is called from the context of the forked process and\nallows for customization of the helper process prior to calling exec. Its\nreturn code gates the continuation of the process, or causes its exit.\nAlso add an arbitrary data pointer to the subprocess_info struct allowing\nfor data to be passed from the caller to the new process, and the\nsubsequent cleanup process\n\nAlso, use this patch to cleanup the cleanup function. It currently takes\nan argp and envp pointer for freeing, which is ugly. Lets instead just\nmake the subprocess_info structure public, and pass that to the cleanup\nand init routines\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nReviewed-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0ac0c0d0f837c499afd02a802f9cf52d3027fa3b", "tree": "c20a7306d4b727722556af1aa5565855686aee07", "parents": [ "6adef3ebe570bcde67fd6c16101451ddde5712b5" ], "author": { "name": "Jack Steiner", "email": "steiner@sgi.com", "time": "Wed May 26 14:42:51 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 27 09:12:44 2010 -0700" }, "message": "cpusets: randomize node rotor used in cpuset_mem_spread_node()\n\nSome workloads that create a large number of small files tend to assign\ntoo many pages to node 0 (multi-node systems).
