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": "b138338056fc423c61a583d45f8aa64cfad87131", "tree": "89079c1f80c62a7fce240942605e869944c81a1e", "parents": [ "18062ca94714a66e75da8a22e010d0e8e61ab4cd" ], "author": { "name": "Frans Pop", "email": "elendil@planet.nl", "time": "Wed Mar 24 07:57:28 2010 +0000" }, "committer": { "name": "David S.

The bug halt occured because the page\nthat I passed to kfree failed the PageCompound and PageSlab test in the slub\nimplementation of kfree. I tracked the problem down to the following set of\nevents:\n\n1) dccp, unlike all other uses of kmem_cache_create, allocates a string\ndynamically when registering a slab cache. This allocated string is freed when\nthe cache is destroyed.\n\n2) Normally, (1) is not an issue, but when Slub is in use, it is possible that\ncaches are \u0027merged\u0027. This process causes multiple caches of simmilar\nconfiguration to use the same cache data structure. When this happens, the new\nname of the cache is effectively dropped.\n\n3) (2) results in kmem_cache_name returning an ambigous value (i.e.\nccid_kmem_cache_destroy, which uses this fuction to retrieve the name pointer\nfor freeing), is no longer guaranteed that the string it assigned is what is\nreturned.\n\n4) If such merge event occurs, ccid_kmem_cache_destroy frees the wrong pointer,\nwhich trips over the BUG in the slub implementation of kfree (since its likely\nnot a slab allocation, but rather a pointer into the static string table\nsection.\n\nSo, what to do about this. At first blush this is pretty clearly a leak in the\ninformation that slub owns, and as such a slub bug. Unfortunately, theres no\nreally good way to fix it, without exposing slub specific implementation details\nto the generic slab interface. Also, even if we could fix this in slub cleanly,\nI think the RCU free option would force us to do lots of string duplication, not\nonly in slub, but in every slab allocator. As such, I\u0027d like to propose this\nsolution. Basically, I just move the storage for the kmem cache name to the\nccid_operations structure. In so doing, we don\u0027t have to do the kstrdup or\nkfree when we allocate/free the various caches for dccp, and so we avoid the\nproblem, by storing names with static memory, rather than heap, the way all\nother calls to kmem_cache_create do.\n\nI\u0027ve tested this out myself here, and it solves the problem quite well.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nAcked-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nSigned-off-by: David S.

The new API has the following benefits:\n\n - Generic usage: For kernel internal use and/or device driver.\n - Provide an API for the most use case.\n - Slim API: The whole API provides 25 functions.\n - Linux style habit.\n - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros\n - Direct copy_to_user from the fifo and copy_from_user into the fifo.\n - The kfifo itself is an in place member of the using data structure, this save an\n indirection access and does not waste the kernel allocator.\n - Lockless access: if only one reader and one writer is active on the fifo,\n which is the common use case, no additional locking is necessary.\n - Remove spinlock - give the user the freedom of choice what kind of locking to use if\n one is required.\n - Ability to handle records. Three type of records are supported:\n - Variable length records between 0-255 bytes, with a record size\n field of 1 bytes.\n - Variable length records between 0-65535 bytes, with a record size\n field of 2 bytes.\n - Fixed size records, which no record size field.\n - Preserve memory resource.\n - Performance!\n - Easy to use!\n\nThis patch:\n\nSince most users want to have the kfifo as part of another object,\nreorganize the code to allow including struct kfifo in another data\nstructure.

If both Acks get\n lost, it is probably better to restart the connection anyway and devising yet\n another special-case does not seem worth the extra complexity.\n\nThe result is a higher utilisation of the available packet space for the data\ntransmission phase (established state) of a connection.\n\nThe patch (over-)estimates the initial overhead to be 32*4 bytes -- commonly\nseen values were around 90 bytes for initial feature-negotiation options.\n\nIt uses sizeof(u32) to mean \"aligned units of 4 bytes\".\nFor consistency, another use of 4-byte alignment is adapted.\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\nSigned-off-by: David S.

For the type-checking the value constraints from RFC 4340\nare used:\n\n * Sequence Window uses the specified Wmin\u003d32, the maximum is ulong (4 bytes),\n tested and confirmed that it works up to 4294967295 - for Gbps speed;\n * Ack Ratio is between 0 .. 0xffff (2-byte unsigned integer);\n * CCIDs are between 0 .. 255;\n * request_retries, retries1, retries2 also between 0..255 for good measure;\n * tx_qlen is checked to be non-negative;\n * sync_ratelimit remains as before.\n\nNotes:\n------\n 1. Die s@sysctl_dccp_feat@sysctl_dccp@g since the sysctls are now in feat.c.\n 2. As pointed out by Arnaldo, the pattern of type-checking repeats itself in\n other places, sometimes with exactly the same kind of definitions (e.g.\n \"static int zero;\").
