There are a number of separate bits. I\u0027ll go over the big bits\n and the odd important other bit, most of the smaller bits are just\n fixes and cleanups. If you want the small bits accounting for, I can\n do that too.\n\n (1) Keyring capacity expansion.\n\n KEYS: Consolidate the concept of an \u0027index key\u0027 for key access\n KEYS: Introduce a search context structure\n KEYS: Search for auth-key by name rather than target key ID\n Add a generic associative array implementation.\n KEYS: Expand the capacity of a keyring\n\n Several of the patches are providing an expansion of the capacity of a\n keyring. Currently, the maximum size of a keyring payload is one page.\n Subtract a small header and then divide up into pointers, that only gives\n you ~500 pointers on an x86_64 box. However, since the NFS idmapper uses\n a keyring to store ID mapping data, that has proven to be insufficient to\n the cause.\n\n Whatever data structure I use to handle the keyring payload, it can only\n store pointers to keys, not the keys themselves because several keyrings\n may point to a single key. This precludes inserting, say, and rb_node\n struct into the key struct for this purpose.\n\n I could make an rbtree of records such that each record has an rb_node\n and a key pointer, but that would use four words of space per key stored\n in the keyring. It would, however, be able to use much existing code.\n\n I selected instead a non-rebalancing radix-tree type approach as that\n could have a better space-used/key-pointer ratio. I could have used the\n radix tree implementation that we already have and insert keys into it by\n their serial numbers, but that means any sort of search must iterate over\n the whole radix tree. Further, its nodes are a bit on the capacious side\n for what I want - especially given that key serial numbers are randomly\n allocated, thus leaving a lot of empty space in the tree.\n\n So what I have is an associative array that internally is a radix-tree\n with 16 pointers per node where the index key is constructed from the key\n type pointer and the key description. This means that an exact lookup by\n type+description is very fast as this tells us how to navigate directly to\n the target key.\n\n I made the data structure general in lib/assoc_array.c as far as it is\n concerned, its index key is just a sequence of bits that leads to a\n pointer. It\u0027s possible that someone else will be able to make use of it\n also. FS-Cache might, for example.\n\n (2) Mark keys as \u0027trusted\u0027 and keyrings as \u0027trusted only\u0027.\n\n KEYS: verify a certificate is signed by a \u0027trusted\u0027 key\n KEYS: Make the system \u0027trusted\u0027 keyring viewable by userspace\n KEYS: Add a \u0027trusted\u0027 flag and a \u0027trusted only\u0027 flag\n KEYS: Separate the kernel signature checking keyring from module signing\n\n These patches allow keys carrying asymmetric public keys to be marked as\n being \u0027trusted\u0027 and allow keyrings to be marked as only permitting the\n addition or linkage of trusted keys.\n\n Keys loaded from hardware during kernel boot or compiled into the kernel\n during build are marked as being trusted automatically. New keys can be\n loaded at runtime with add_key(). They are checked against the system\n keyring contents and if their signatures can be validated with keys that\n are already marked trusted, then they are marked trusted also and can\n thus be added into the master keyring.\n\n Patches from Mimi Zohar make this usable with the IMA keyrings also.\n\n (3) Remove the date checks on the key used to validate a module signature.\n\n X.509: Remove certificate date checks\n\n It\u0027s not reasonable to reject a signature just because the key that it was\n generated with is no longer valid datewise - especially if the kernel\n hasn\u0027t yet managed to set the system clock when the first module is\n loaded - so just remove those checks.\n\n (4) Make it simpler to deal with additional X.509 being loaded into the kernel.\n\n KEYS: Load *.x509 files into kernel keyring\n KEYS: Have make canonicalise the paths of the X.509 certs better to deduplicate\n\n The builder of the kernel now just places files with the extension \".x509\"\n into the kernel source or build trees and they\u0027re concatenated by the\n kernel build and stuffed into the appropriate section.\n\n (5) Add support for userspace kerberos to use keyrings.\n\n KEYS: Add per-user_namespace registers for persistent per-UID kerberos caches\n KEYS: Implement a big key type that can save to tmpfs\n\n Fedora went to, by default, storing kerberos tickets and tokens in tmpfs.\n We looked at storing it in keyrings instead as that confers certain\n advantages such as tickets being automatically deleted after a certain\n amount of time and the ability for the kernel to get at these tokens more\n easily.\n\n To make this work, two things were needed:\n\n (a) A way for the tickets to persist beyond the lifetime of all a user\u0027s\n sessions so that cron-driven processes can still use them.\n\n The problem is that a user\u0027s session keyrings are deleted when the\n session that spawned them logs out and the user\u0027s user keyring is\n deleted when the UID is deleted (typically when the last log out\n happens), so neither of these places is suitable.\n\n I\u0027ve added a system keyring into which a \u0027persistent\u0027 keyring is\n created for each UID on request. Each time a user requests their\n persistent keyring, the expiry time on it is set anew. If the user\n doesn\u0027t ask for it for, say, three days, the keyring is automatically\n expired and garbage collected using the existing gc. All the kerberos\n tokens it held are then also gc\u0027d.\n\n (b) A key type that can hold really big tickets (up to 1MB in size).\n\n The problem is that Active Directory can return huge tickets with lots\n of auxiliary data attached.

Some genetlink protocols we passing in constant\n counts for their ops array rather than something like\n ARRAY_SIZE(ops) or similar. Also, some genetlink protocols were\n using fixed IDs for their multicast groups.\n\n We have to retain these fixed IDs to keep existing userland tools\n working, but reserve them so that other multicast groups used by\n other protocols can not possibly conflict.\n\n In dealing with these two problems, we actually now use less state\n management for genetlink operations and multicast groups.\n\n 2) When configuring interface hardware timestamping, fix several\n drivers that simply do not validate that the hwtstamp_config value\n is one the driver actually supports.

This issue was exposed by Roland\nDreier in a previous review[1].\n\nSo the following patch is an attempt to a revised extensible command\ninfrastructure.\n\nThis improved extensible command infrastructure distinguish between\ncore (eg. legacy)\u0027s command/response buffers from provider\n(eg. hardware)\u0027s command/response buffers: each extended command\nimplementing function is given a struct ib_udata to hold core\n(eg. uverbs) input and output buffers, and another struct ib_udata to\nhold the hw (eg. provider) input and output buffers.\n\nHaving those buffers identified separately make it easier to increase\none buffer to support extension without having to add some code to\nguess the exact size of each command/response parts: This should make\nthe extended functions more reliable.\n\nAdditionally, instead of relying on command identifier being greater\nthan IB_USER_VERBS_CMD_THRESHOLD, the proposed infrastructure rely on\nunused bits in command field: on the 32 bits provided by command\nfield, only 6 bits are really needed to encode the identifier of\ncommands currently supported by the kernel. (Even using only 6 bits\nleaves room for about 23 new commands).\n\nSo this patch makes use of some high order bits in command field to\nstore flags, leaving enough room for more command identifiers than one\nwill ever need (eg. 256).\n\nThe new flags are used to specify if the command should be processed\nas an extended one or a legacy one. While designing the new command\nformat, care was taken to make usage of flags itself extensible.\n\nUsing high order bits of the commands field ensure that newer\nlibibverbs on older kernel will properly fail when trying to call\nextended commands. On the other hand, older libibverbs on newer kernel\nwill never be able to issue calls to extended commands.\n\nThe extended command header includes the optional response pointer so\nthat output buffer length and output buffer pointer are located\ntogether in the command, allowing proper parameters checking. This\nshould make implementing functions easier and safer.\n\nAdditionally the extended header ensure 64bits alignment, while making\nall sizes multiple of 8 bytes, extending the maximum buffer size:\n\n legacy extended\n\n Maximum command buffer: 256KBytes 1024KBytes (512KBytes + 512KBytes)\n Maximum response buffer: 256KBytes 1024KBytes (512KBytes + 512KBytes)\n\nFor the purpose of doing proper buffer size accounting, the headers\nsize are no more taken in account in \"in_words\".\n\nOne of the odds of the current extensible infrastructure, reading\ntwice the \"legacy\" command header, is fixed by removing the \"legacy\"\ncommand header from the extended command header: they are processed as\ntwo different parts of the command: memory is read once and\ninformation are not duplicated: it\u0027s making clear that\u0027s an extended\ncommand scheme and not a different command scheme.\n\nThe proposed scheme will format input (command) and output (response)\nbuffers this way:\n\n- command:\n\n legacy header +\n extended header +\n command data (core + hw):\n\n +----------------------------------------+\n | flags | 00 00 | command |\n | in_words | out_words |\n +----------------------------------------+\n | response |\n | response |\n | provider_in_words | provider_out_words |\n | padding |\n +----------------------------------------+\n | |\n . \u003cuverbs input\u003e .\n . (in_words * 8) .\n | |\n +----------------------------------------+\n | |\n . \u003cprovider input\u003e .\n . (provider_in_words * 8) .\n | |\n +----------------------------------------+\n\n- response, if present:\n\n +----------------------------------------+\n | |\n . \u003cuverbs output space\u003e .\n . (out_words * 8) .\n | |\n +----------------------------------------+\n | |\n . \u003cprovider output space\u003e .\n . (provider_out_words * 8) .\n | |\n +----------------------------------------+\n\nThe overall design is to ensure that the extensible infrastructure is\nitself extensible while begin more reliable with more input and bound\nchecking.\n\nNote:\n\nThe unused field in the extended header would be perfect candidate to\nhold the command \"comp_mask\" (eg. bit field used to handle\ncompatibility). This was suggested by Roland Dreier in a previous\nreview[2]. But \"comp_mask\" field is likely to be present in the uverb\ninput and/or provider input, likewise for the response, as noted by\nMatan Barak[3], so it doesn\u0027t make sense to put \"comp_mask\" in the\nheader.\n\n[1]:\nhttp://marc.info/?i\u003dCAL1RGDWxmM17W2o_era24A-TTDeKyoL6u3NRu_\u003dt_dhV_ZA9MA@mail.gmail.com\n\n[2]:\nhttp://marc.info/?i\u003dCAL1RGDXJtrc849M6_XNZT5xO1+ybKtLWGq6yg6LhoSsKpsmkYA@mail.gmail.com\n\n[3]:\nhttp://marc.info/?i\u003d525C1149.6000701@mellanox.com\n\nSigned-off-by: Yann Droneaud \u003cydroneaud@opteya.com\u003e\nLink: http://marc.info/?i\u003dcover.1383773832.git.ydroneaud@opteya.com\n\n[ Convert \"ret ? ret : 0\" to the equivalent \"ret\". - Roland ]\n\nSigned-off-by: Roland Dreier \u003croland@purestorage.com\u003e\n" }, { "commit": "2490f20be496c2da14ae4632a8c60e0633e97fd0", "tree": "4c80e3d5dc5004eebd5fc3dcccf4b26f2b16d644", "parents": [ "58913efba9c3aa7992f2a4d630135ded833d988e" ], "author": { "name": "Yann Droneaud", "email": "ydroneaud@opteya.com", "time": "Wed Nov 06 23:21:48 2013 +0100" }, "committer": { "name": "Roland Dreier", "email": "roland@purestorage.com", "time": "Sun Nov 17 08:22:08 2013 -0800" }, "message": "IB/core: Remove ib_uverbs_flow_spec structure from userspace\n\nThe structure holding any types of flow_spec is of no use to\nuserspace.

It is now safe\nto put const data into a non const FIFO and the API will now generate a\ncompiler warning when reading from the fifo where the destination\naddress is pointing to a const variable.\n\nAs a side effect the kfifo_put() does now expect the value of an element\ninstead a pointer to the element. This was suggested Russell King. It\nmake the handling of the kfifo_put easier since there is no need to\ncreate a helper variable for getting the address of a pointer or to pass\nintegers of different sizes.\n\nIMHO the API break is okay, since there are currently only six users of\nkfifo_put().\n\nThe code is also cleaner by kicking out the \"if (0)\" expressions.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Stefani Seibold \u003cstefani@seibold.net\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Hauke Mehrtens \u003chauke@hauke-m.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b89241e8cdb8321c20546d47645a9b65b58113b5", "tree": "de330bd740b3f7e24f834df48b3db47dc1c75889", "parents": [ "ca5ecd64c2cdbcd316d789467147e732746f39fa" ], "author": { "name": "Christoph Hellwig", "email": "hch@infradead.org", "time": "Thu Nov 14 14:32:11 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Nov 15 09:32:22 2013 +0900" }, "message": "llists: move llist_reverse_order from raid5 to llist.c\n\nMake this useful helper available for other users.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nReviewed-by: Jan Kara \u003cjack@suse.cz\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nCc: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "7cf64f861b7a43b395f0855994003254b06a7e5a", "tree": "9761b86bd60360bd1daa88fafee54b1bb7d4f06a", "parents": [ "40c01e8bd5575e32633192513e09eac7155d6926" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Thu Nov 14 14:32:09 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Nov 15 09:32:22 2013 +0900" }, "message": "kernel-provide-a-__smp_call_function_single-stub-for-config_smp-fix\n\nx86_64 allnoconfig:\n\n kernel/up.c:25: error: redefinition of \u0027__smp_call_function_single\u0027\n include/linux/smp.h:154: note: previous definition of \u0027__smp_call_function_single\u0027 was here\n\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Jan Kara \u003cjack@suse.cz\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0a06ff068f1255bcd7965ab07bc0f4adc3eb639a", "tree": "419618fc4573c9d0ff17f383e84fc41071d50004", "parents": [ "fc21c0cff2f425891b28ff6fb6b03b325c977428" ], "author": { "name": "Christoph Hellwig", "email": "hch@infradead.org", "time": "Thu Nov 14 14:32:07 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Nov 15 09:32:22 2013 +0900" }, "message": "kernel: remove CONFIG_USE_GENERIC_SMP_HELPERS\n\nWe\u0027ve switched over every architecture that supports SMP to it, so\nremove the new useless config variable.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Jan Kara \u003cjack@suse.cz\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fc21c0cff2f425891b28ff6fb6b03b325c977428", "tree": "920565aba013c83db09bc677c15d17280eee0707", "parents": [ "c853b167e6ec1f25023cfc58ba2f43f9f6f5b49b" ], "author": { "name": "Christoph Hellwig", "email": "hch@infradead.org", "time": "Thu Nov 14 14:32:06 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Nov 15 09:32:22 2013 +0900" }, "message": "revert \"softirq: Add support for triggering softirq work on softirqs\"\n\nThis commit was incomplete in that code to remove items from the per-cpu\nlists was missing and never acquired a user in the 5 years it has been in\nthe tree.
