When enabled, likely candidates among incoming and\noutgoing network packets are offered to the PHY driver for possible\ntime stamping. When accepted by the PHY driver, incoming packets are\ndeferred for later delivery by the driver.\n\nThe patch also adds phylib driver methods for the SIOCSHWTSTAMP ioctl\nand callbacks for transmit and receive time stamping. Drivers may\noptionally implement these functions.\n\nSigned-off-by: Richard Cochran \u003crichard.cochran@omicron.at\u003e\nSigned-off-by: David S.

This runs into trouble when a packet\nprocessing is delayed in which case it may execute out of another\nthread\u0027s context.\n\nFurthermore, even when a packet is not delayed we may fail to\nclassify it if soft IRQs have been disabled, because this scenario\nis indistinguishable from one where a packet unrelated to the\ncurrent thread is processed by a real soft IRQ.\n\nIn fact, the current semantics is inherently broken, as a single\nskb may be constructed out of the writes of two different tasks.\nA different manifestation of this problem is when the TCP stack\ntransmits in response of an incoming ACK. This is currently\nunclassified.\n\nAs we already have a concept of packet ownership for accounting\npurposes in the skb-\u003esk pointer, this is a natural place to store\nthe classid in a persistent manner.\n\nThis patch adds the cls_cgroup classid in struct sock, filling up\nan existing hole on 64-bit :)\n\nThe value is set at socket creation time. So all sockets created\nvia socket(2) automatically gains the ID of the thread creating it.\nWhenever another process touches the socket by either reading or\nwriting to it, we will change the socket classid to that of the\nprocess if it has a valid (non-zero) classid.\n\nFor sockets created on inbound connections through accept(2), we\ninherit the classid of the original listening socket through\nsk_clone, possibly preceding the actual accept(2) call.\n\nIn order to minimise risks, I have not made this the authoritative\nclassid. For now it is only used as a backup when we execute\nwith soft IRQs disabled. Once we\u0027re completely happy with its\nsemantics we can use it as the sole classid.\n\nFootnote: I have rearranged the error path on cls_group module\ncreation. If we didn\u0027t do this, then there is a window where\nsomeone could create a tc rule using cls_group before the cgroup\nsubsystem has been registered.\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nSigned-off-by: David S.

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": "71c5c1595c04852d6fbf3c4882b47b30b61a4d32", "tree": "d95c64c5b752d37e7d1235e52f0c1fceb816c2ec", "parents": [ "f49c57e141c7f53353e4265a31dc2324e6215037" ], "author": { "name": "Brandon L Black", "email": "blblack@gmail.com", "time": "Fri Mar 26 16:18:03 2010 +0000" }, "committer": { "name": "David S.

This value was\nexported via a SOL_PACKET level cmsg. AFter I completed that work it was\nrequested that this feature be generalized so that any datagram oriented socket\ncould make use of this option. As such I\u0027ve created this patch, It creates a\nnew SOL_SOCKET level option called SO_RXQ_OVFL, which when enabled exports a\nSOL_SOCKET level cmsg that reports the nubmer of times the sk_receive_queue\noverflowed between any two given frames. It also augments the AF_PACKET\nprotocol to take advantage of this new feature (as it previously did not touch\nsk-\u003esk_drops, which this patch uses to record the overflow count). Tested\nsuccessfully by me.\n\nNotes:\n\n1) Unlike my previous patch, this patch simply records the sk_drops value, which\nis not a number of drops between packets, but rather a total number of drops.\nDeltas must be computed in user space.\n\n2) While this patch currently works with datagram oriented protocols, it will\nalso be accepted by non-datagram oriented protocols. I\u0027m not sure if thats\nagreeable to everyone, but my argument in favor of doing so is that, for those\nprotocols which aren\u0027t applicable to this option, sk_drops will always be zero,\nand reporting no drops on a receive queue that isn\u0027t used for those\nnon-participating protocols seems reasonable to me. This also saves us having\nto code in a per-protocol opt in mechanism.\n\n3) This applies cleanly to net-next assuming that commit\n977750076d98c7ff6cbda51858bb5a5894a9d9ab (my af packet cmsg patch) is reverted\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: David S.

Andi Kleen suggested moving the handling\nof that bit into fasync(); this patch does exactly that. As a result, we\nhave a couple of internal API changes: fasync() must now manage the FASYNC\nbit, and it will be called without the BKL held.\n\nAs it happens, every fasync() implementation in the kernel with one\nexception calls fasync_helper(). So, if we make fasync_helper() set the\nFASYNC bit, we can avoid making any changes to the other fasync()\nfunctions - as long as those functions, themselves, have proper locking.\nMost fasync() implementations do nothing but call fasync_helper() - which\nhas its own lock - so they are easily verified as correct. The BKL had\nalready been pushed down into the rest.\n\nThe networking code has its own version of fasync_helper(), so that code\nhas been augmented with explicit FASYNC bit handling.\n\nCc: Al Viro \u003cviro@ZenIV.linux.org.uk\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Jonathan Corbet \u003ccorbet@lwn.net\u003e\n" }, { "commit": "20d4947353be60e909e6b1a79d241457edd6833f", "tree": "939ced518fc52e57df9ee9efb0cd14b6e26a3bc4", "parents": [ "ac45f602ee3d1b6f326f68bc0c2591ceebf05ba4" ], "author": { "name": "Patrick Ohly", "email": "patrick.ohly@intel.com", "time": "Thu Feb 12 05:03:38 2009 +0000" }, "committer": { "name": "David S.

The addition of this system call\nmatches analogous changes in 2.6.27 (dup3(), evenfd2(), signalfd4(),\ninotify_init1(), epoll_create1(), pipe2()) which added new system calls\nthat differed from analogous traditional system calls in adding a flags\nargument that can be used to access additional functionality.\n\nThe accept4() system call is exactly the same as accept(), except that\nit adds a flags bit-mask argument. Two flags are initially implemented.\n(Most of the new system calls in 2.6.27 also had both of these flags.)\n\nSOCK_CLOEXEC causes the close-on-exec (FD_CLOEXEC) flag to be enabled\nfor the new file descriptor returned by accept4().

There is AFAICS no demonstrated\n use case that the sigset argument of this syscall serves that couldn\u0027t\n equally be served by the use of pselect/ppoll/epoll_pwait + traditional\n accept(). Roland seems to concur with this opinion\n (http://thread.gmane.org/gmane.linux.kernel/723953/focus\u003d732255). I\n have (more than once) asked Ulrich to explain otherwise\n (http://thread.gmane.org/gmane.linux.kernel/723952/focus\u003d731018), but he\n does not respond, so one is left to assume that he doesn\u0027t know of such\n a case.\n\n* The use of a sigset argument is not consistent with other I/O APIs\n that can block on a single file descriptor (e.g., read(), recv(),\n connect()).\n\n* The behavior of paccept() when interrupted by a signal is IMO strange:\n the kernel restarts the system call if SA_RESTART was set for the\n handler. I think that it should not do this -- that it should behave\n consistently with paccept()/ppoll()/epoll_pwait(), which never restart,\n regardless of SA_RESTART. The reasoning here is that the very purpose\n of paccept() is to wait for a connection or a signal, and that\n restarting in the latter case is probably never useful. (Note: Roland\n disagrees on this point, believing that rather paccept() should be\n consistent with accept() in its behavior wrt EINTR\n (http://thread.gmane.org/gmane.linux.kernel/723953/focus\u003d732255).)\n\nI believe that instead, a simpler API, consistent with Ulrich\u0027s other\nrecent additions, is preferable:\n\naccept4(int fd, struct sockaddr *sa, socklen_t *salen, ind flags);\n\n(This simpler API was originally proposed by Ulrich:\nhttp://thread.gmane.org/gmane.linux.network/92072)\n\nIf this simpler API is added, then if we later decide that the sigset\nargument really is required, then a suitable bit in \u0027flags\u0027 could be added\nto indicate the presence of the sigset argument.\n\nAt this point, I am hoping we either will get a counter-argument from\nUlrich about why we really do need paccept()\u0027s sigset argument, or that he\nwill resubmit the original accept4() patch.\n\nSigned-off-by: Michael Kerrisk \u003cmtk.manpages@gmail.com\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nCc: Alan Cox \u003calan@redhat.com\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Jakub Jelinek \u003cjakub@redhat.com\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "51cc50685a4275c6a02653670af9f108a64e01cf", "tree": "819d47bd2b0c8a9d1835d863853804b0a0242b97", "parents": [ "d91958815d214ea365b98cbff6215383897edcb6" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Fri Jul 25 19:45:34 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jul 26 12:00:07 2008 -0700" }, "message": "SL*B: drop kmem cache argument from constructor\n\nKmem cache passed to constructor is only needed for constructors that are\nthemselves multiplexeres.

In the\nprocess of doing that, it also provides infrastructure for keeping track of\nthe number of writers to any given mount.\n\nThis has a number of uses. It allows chroots to have parts of filesystems\nwritable. It will be useful for containers in the future because users may\nhave root inside a container, but should not be allowed to write to\nsomefilesystems. This also replaces patches that vserver has had out of the\ntree for several years.\n\nIt allows security enhancement by making sure that parts of your filesystem\nread-only (such as when you don\u0027t trust your FTP server), when you don\u0027t want\nto have entire new filesystems mounted, or when you want atime selectively\nupdated. I\u0027ve been using the following script to test that the feature is\nworking as desired. It takes a directory and makes a regular bind and a r/o\nbind mount of it.

I think SLUB_DEBUG_INITIAL is too problematic to make real\nuse of, difficult to understand and there are easier ways to accomplish the\nsame effect (i.e. add debug code before kfree).\n\nThere is a related flag SLAB_CTOR_VERIFY that is frequently checked to be\nclear in fs inode caches. Remove the pointless checks (they would even be\npointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors.\n\nThis is the last slab flag that SLUB did not support. Remove the check for\nunimplemented flags from SLUB.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "7c81fd8bfbaa9732eca142350de5154da6919411", "tree": "4187e8a4921be94acfb8ef9542f4badaee58de67", "parents": [ "92f37fd2ee805aa77925c1e64fd56088b46094fc" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Sat Mar 10 00:39:35 2007 -0300" }, "committer": { "name": "David S.
