This\nallows the compiler to choose automatically how to optimize these for\nsize or speed.\n\nSHARE-related functionality doesn\u0027t seem to be used, as those\nfunctions are hiding behind a #define that isn\u0027t set anywhere that I\ncan find. And, they\u0027ve been in there forever (at least as far back as\nthe kernel\u0027s git history goes), yet remain unused. Let\u0027s take the\nopportunity to bin them. It should be easy enough for someone to\nintroduce proper XDR functions if at some point SHARE-related NLM\nfunctionality is desired.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nTested-by: J.

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" }, { "commit": "7e469af97eed947ba9204712601281a69ae8eb6c", "tree": "f4488e393995ae523ed6dea5370ddad7aa1505b5", "parents": [ "cdd30fa1664e0245fa64330c7cc2ddab7e47c223" ], "author": { "name": "Jeff Layton", "email": "jlayton@redhat.com", "time": "Fri Feb 05 15:09:22 2010 -0500" }, "committer": { "name": "J.

replies\n\nWhen rpc.statd starts up in user space at boot time, it attempts to\nwrite the latest NSM local state number into\n/proc/sys/fs/nfs/nsm_local_state.\n\nIf lockd.ko isn\u0027t loaded yet (as is the case in most configurations),\nthat file doesn\u0027t exist, thus the kernel\u0027s NSM state remains set to\nits initial value of zero during lockd operation.\n\nThis is a problem because rpc.statd and lockd use the NSM state number\nto prevent repeated lock recovery on rebooted hosts. If lockd sends\na zero NSM state, but then a delayed SM_NOTIFY with a real NSM state\nnumber is received, there is no way for lockd or rpc.statd to\ndistinguish that stale SM_NOTIFY from an actual reboot. Thus lock\nrecovery could be performed after the rebooted host has already\nstarted reclaiming locks, and those locks will be lost.\n\nWe could change /etc/init.d/nfslock so it always modprobes lockd.ko\nbefore starting rpc.statd. However, if lockd.ko is ever unloaded\nand reloaded, we are back at square one, since the NSM state is not\npreserved across an unload/reload cycle. This may happen frequently\non clients that use automounter. A period of NFS inactivity causes\nlockd.ko to be unloaded, and the kernel loses its NSM state setting.\n\nInstead, let\u0027s use the fact that rpc.statd plants the local system\u0027s\nNSM state in every SM_MON (and SM_UNMON) reply. lockd performs a\nsynchronous SM_MON upcall to the local rpc.statd _before_ sending its\nfirst NLM request to a new remote. This would permit rpc.statd to\nprovide the current NSM state to lockd, even after lockd.ko had been\nunloaded and reloaded.\n\nNote that NLMPROC_LOCK arguments are constructed before the\nnsm_monitor() call, so we have to rearrange argument construction very\nslightly to make this all work out.\n\nAnd, the kernel appears to treat NSM state as a u32 (see struct\nnlm_args and nsm_res). Make nsm_local_state a u32 as well, to ensure\nwe don\u0027t get bogus comparison results.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "5cd973c44a92f4abf8f7084c804089b3eaa7b4bf", "tree": "7bea559ab6c0a2ab4885a6064147b0cae20b8293", "parents": [ "3f09df70e3a33590ae5a97b8a15486d3711c7065" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Jun 17 13:23:01 2009 -0700" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Jun 17 13:23:01 2009 -0700" }, "message": "NFSv4/NLM: Push file locking BKL dependencies down into the NLM layer\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "7eef4091a653c243a87e5375c54504cc03bec4d8", "tree": "f65b77f830b2c8f7d014512badfef5df0d591ee9", "parents": [ "0a93a47f042c459f0f46942c3a920e3c81878031", "07a2039b8eb0af4ff464efd3dfd95de5c02648c6" ], "author": { "name": "J.

Part of this service\nincludes a second protocol, known as NSM, which is a reboot\nnotification service. NLM uses this service to determine when to\nreclaim locks or enter a grace period after a client or server reboots.\n\nThe NLM service (implemented by lockd in the Linux kernel) contacts\nthe local NSM service (implemented by rpc.statd in Linux user space)\nvia NSM protocol upcalls to register a callback when a particular\nremote peer reboots.\n\nTo match the callback to the correct remote peer, the NLM service\nconstructs a cookie that it passes in the request. The NSM service\npasses that cookie back to the NLM service when it is notified that\nthe given remote peer has indeed rebooted.\n\nCurrently on Linux, the cookie is the raw 32-bit IPv4 address of the\nremote peer. To support IPv6 addresses, which are larger, we could\nuse all 16 bytes of the cookie to represent a full IPv6 address,\nalthough we still can\u0027t represent an IPv6 address with a scope ID in\njust 16 bytes.\n\nInstead, to avoid the need for future changes to support additional\naddress types, we\u0027ll use a manufactured value for the cookie, and use\nthat to find the corresponding nsm_handle struct in the kernel during\nthe NLMPROC_SM_NOTIFY callback.\n\nThis should provide complete support in the kernel\u0027s NSM\nimplementation for IPv6 hosts, while remaining backwards compatible\nwith older rpc.statd implementations.\n\nNote we also deal with another case where nsm_use_hostnames can change\nwhile there are outstanding notifications, possibly resulting in the\nloss of reboot notifications. After this patch, the priv cookie is\nalways used to lookup rebooted hosts in the kernel.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nSigned-off-by: J.
