      "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files.  percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed.  Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability.  As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n  http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n  only the necessary includes are there.  ie. if only gfp is used,\n  gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n  blocks and try to put the new include such that its order conforms\n  to its surrounding.  It\u0027s put in the include block which contains\n  core kernel includes, in the same order that the rest are ordered -\n  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n  doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n  because the file doesn\u0027t have fitting include block), it prints out\n  an error message indicating which .h file needs to be added to the\n  file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n   over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n   and ~3000 slab.h inclusions.  The script emitted errors for ~400\n   files.\n\n2. Each error was manually checked.  Some didn\u0027t need the inclusion,\n   some needed manual addition while adding it to implementation .h or\n   embedding .c file was more appropriate for others.  This step added\n   inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n   from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n   e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n   APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n   editing them as sprinkling gfp.h and slab.h inclusions around .h\n   files could easily lead to inclusion dependency hell.  Most gfp.h\n   inclusion directives were ignored as stuff from gfp.h was usually\n   wildly available and often used in preprocessor macros.  Each\n   slab.h inclusion directive was examined and added manually as\n   necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my\n   distributed build env didn\u0027t work with gcov compiles) and a few\n   more options had to be turned off depending on archs to make things\n   build (like ipr on powerpc/64 which failed due to missing writeq).\n\n   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n   * powerpc and powerpc64 SMP allmodconfig\n   * sparc and sparc64 SMP allmodconfig\n   * ia64 SMP allmodconfig\n   * s390 SMP allmodconfig\n   * alpha SMP allmodconfig\n   * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n   a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n"

The user struct pins its user namespace.\n        3. The user namespace pins the struct user which created it.\n\nUser namespaces are cloned during copy_creds().

I don\u0027t imagine\n\u003e     the new root user being used for anything other than filling in a cred\n\u003e     struct.\n\u003e\n\u003e     This also permits me to get rid of a get_uid() and a free_uid(), as the\n\u003e     reference the creds were holding on the old user_struct can just be\n\u003e     transferred to the new namespace\u0027s creator pointer.\n\u003e\n\u003e (6) Makes create_user_ns() reset the UIDs and GIDs of the creds under\n\u003e     preparation rather than doing it in copy_creds().\n\u003e\n\u003eDavid\n\n\u003eSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n\nChangelog:\n\tOct 20: integrate dhowells comments\n\t\t1. leave thread_keyring alone\n\t\t2. use current_user_ns() in set_user()\n\nSigned-off-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\n"

      "message": "eCryptfs: introduce device handle for userspace daemon communications\n\nA regular device file was my real preference from the get-go, but I went with\nnetlink at the time because I thought it would be less complex for managing\nsend queues (i.e., just do a unicast and move on).  It turns out that we do\nnot really get that much complexity reduction with netlink, and netlink is\nmore heavyweight than a device handle.\n\nIn addition, the netlink interface to eCryptfs has been broken since 2.6.24.\nI am assuming this is a bug in how eCryptfs uses netlink, since the other\nin-kernel users of netlink do not seem to be having any problems.  I have had\none report of a user successfully using eCryptfs with netlink on 2.6.24, but\nfor my own systems, when starting the userspace daemon, the initial helo\nmessage sent to the eCryptfs kernel module results in an oops right off the\nbat.  I spent some time looking at it, but I have not yet found the cause.\nThe netlink interface breaking gave me the motivation to just finish my patch\nto migrate to a regular device handle.  If I cannot find out soon why the\nnetlink interface in eCryptfs broke, I am likely to just send a patch to\ndisable it in 2.6.24 and 2.6.25.  I would like the device handle to be the\npreferred means of communicating with the userspace daemon from 2.6.26 on\nforward.\n\nThis patch:\n\nFunctions to facilitate reading and writing to the eCryptfs miscellaneous\ndevice handle.  This will replace the netlink interface as the preferred\nmechanism for communicating with the userspace eCryptfs daemon.\n\nEach user has his own daemon, which registers itself by opening the eCryptfs\ndevice handle.  Only one daemon per euid may be registered at any given time.\nThe eCryptfs module sends a message to a daemon by adding its message to the\ndaemon\u0027s outgoing message queue.  The daemon reads the device handle to get\nthe oldest message off the queue.\n\nIncoming messages from the userspace daemon are immediately handled.  If the\nmessage is a response, then the corresponding process that is blocked waiting\nfor the response is awakened.\n\nSigned-off-by: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
