      "message": "[PATCH] keys: Permit running process to instantiate keys\n\nMake it possible for a running process (such as gssapid) to be able to\ninstantiate a key, as was requested by Trond Myklebust for NFS4.\n\nThe patch makes the following changes:\n\n (1) A new, optional key type method has been added. This permits a key type\n     to intercept requests at the point /sbin/request-key is about to be\n     spawned and do something else with them - passing them over the\n     rpc_pipefs files or netlink sockets for instance.\n\n     The uninstantiated key, the authorisation key and the intended operation\n     name are passed to the method.\n\n (2) The callout_info is no longer passed as an argument to /sbin/request-key\n     to prevent unauthorised viewing of this data using ps or by looking in\n     /proc/pid/cmdline.\n\n     This means that the old /sbin/request-key program will not work with the\n     patched kernel as it will expect to see an extra argument that is no\n     longer there.\n\n     A revised keyutils package will be made available tomorrow.\n\n (3) The callout_info is now attached to the authorisation key. Reading this\n     key will retrieve the information.\n\n (4) A new field has been added to the task_struct. This holds the\n     authorisation key currently active for a thread. Searches now look here\n     for the caller\u0027s set of keys rather than looking for an auth key in the\n     lowest level of the session keyring.\n\n     This permits a thread to be servicing multiple requests at once and to\n     switch between them. Note that this is per-thread, not per-process, and\n     so is usable in multithreaded programs.\n\n     The setting of this field is inherited across fork and exec.\n\n (5) A new keyctl function (KEYCTL_ASSUME_AUTHORITY) has been added that\n     permits a thread to assume the authority to deal with an uninstantiated\n     key. Assumption is only permitted if the authorisation key associated\n     with the uninstantiated key is somewhere in the thread\u0027s keyrings.\n\n     This function can also clear the assumption.\n\n (6) A new magic key specifier has been added to refer to the currently\n     assumed authorisation key (KEY_SPEC_REQKEY_AUTH_KEY).\n\n (7) Instantiation will only proceed if the appropriate authorisation key is\n     assumed first. The assumed authorisation key is discarded if\n     instantiation is successful.\n\n (8) key_validate() is moved from the file of request_key functions to the\n     file of permissions functions.\n\n (9) The documentation is updated.\n\nFrom: \u003cValdis.Kletnieks@vt.edu\u003e\n\n    Build fix.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: Alexander Zangerl \u003caz@bond.edu.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] keys: Discard duplicate keys from a keyring on link\n\nCause any links within a keyring to keys that match a key to be linked into\nthat keyring to be discarded as a link to the new key is added.  The match is\ncontingent on the type and description strings being the same.\n\nThis permits requests, adds and searches to displace negative, expired,\nrevoked and dead keys easily.  After some discussion it was concluded that\nduplicate valid keys should probably be discarded also as they would otherwise\nhide the new key.\n\nSince request_key() is intended to be the primary method by which keys are\nadded to a keyring, duplicate valid keys wouldn\u0027t be an issue there as that\nfunction would return an existing match in preference to creating a new key.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: Alexander Zangerl \u003caz@bond.edu.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

This makes\nSUID binaries easier to support without going as far as labelling keys and key\ntargets using the LSM facilities.\n\nThis patch adds a second \"pointer type\" to key structures (struct key_ref *)\nthat can have the bottom bit of the address set to indicate the possession of\na key. This is propagated through searches from the keyring to the discovered\nkey. It has been made a separate type so that the compiler can spot attempts\nto dereference a potentially incorrect pointer.\n\nThe \"possession\" attribute can\u0027t be attached to a key structure directly as\nit\u0027s not an intrinsic property of a key.\n\nPointers to keys have been replaced with struct key_ref *\u0027s wherever\npossession information needs to be passed through.\n\nThis does assume that the bottom bit of the pointer will always be zero on\nreturn from kmem_cache_alloc().\n\nThe key reference type has been made into a typedef so that at least it can be\nlocated in the sources, even though it\u0027s basically a pointer to an undefined\ntype.

      "message": "[PATCH] Keys: Make request-key create an authorisation key\n\nThe attached patch makes the following changes:\n\n (1) There\u0027s a new special key type called \".request_key_auth\".\n\n     This is an authorisation key for when one process requests a key and\n     another process is started to construct it. This type of key cannot be\n     created by the user; nor can it be requested by kernel services.\n\n     Authorisation keys hold two references:\n\n     (a) Each refers to a key being constructed. When the key being\n     \t constructed is instantiated the authorisation key is revoked,\n     \t rendering it of no further use.\n\n     (b) The \"authorising process\". This is either:\n\n     \t (i) the process that called request_key(), or:\n\n     \t (ii) if the process that called request_key() itself had an\n     \t      authorisation key in its session keyring, then the authorising\n     \t      process referred to by that authorisation key will also be\n     \t      referred to by the new authorisation key.\n\n\t This means that the process that initiated a chain of key requests\n\t will authorise the lot of them, and will, by default, wind up with\n\t the keys obtained from them in its keyrings.\n\n (2) request_key() creates an authorisation key which is then passed to\n     /sbin/request-key in as part of a new session keyring.\n\n (3) When request_key() is searching for a key to hand back to the caller, if\n     it comes across an authorisation key in the session keyring of the\n     calling process, it will also search the keyrings of the process\n     specified therein and it will use the specified process\u0027s credentials\n     (fsuid, fsgid, groups) to do that rather than the calling process\u0027s\n     credentials.\n\n     This allows a process started by /sbin/request-key to find keys belonging\n     to the authorising process.\n\n (4) A key can be read, even if the process executing KEYCTL_READ doesn\u0027t have\n     direct read or search permission if that key is contained within the\n     keyrings of a process specified by an authorisation key found within the\n     calling process\u0027s session keyring, and is searchable using the\n     credentials of the authorising process.\n\n     This allows a process started by /sbin/request-key to read keys belonging\n     to the authorising process.\n\n (5) The magic KEY_SPEC_*_KEYRING key IDs when passed to KEYCTL_INSTANTIATE or\n     KEYCTL_NEGATE will specify a keyring of the authorising process, rather\n     than the process doing the instantiation.\n\n (6) One of the process keyrings can be nominated as the default to which\n     request_key() should attach new keys if not otherwise specified.

      "message": "[PATCH] keys: Discard key spinlock and use RCU for key payload\n\nThe attached patch changes the key implementation in a number of ways:\n\n (1) It removes the spinlock from the key structure.\n\n (2) The key flags are now accessed using atomic bitops instead of\n     write-locking the key spinlock and using C bitwise operators.\n\n     The three instantiation flags are dealt with with the construction\n     semaphore held during the request_key/instantiate/negate sequence, thus\n     rendering the spinlock superfluous.\n\n     The key flags are also now bit numbers not bit masks.\n\n (3) The key payload is now accessed using RCU. This permits the recursive\n     keyring search algorithm to be simplified greatly since no locks need be\n     taken other than the usual RCU preemption disablement. Searching now does\n     not require any locks or semaphores to be held; merely that the starting\n     keyring be pinned.\n\n (4) The keyring payload now includes an RCU head so that it can be disposed\n     of by call_rcu(). This requires that the payload be copied on unlink to\n     prevent introducing races in copy-down vs search-up.\n\n (5) The user key payload is now a structure with the data following it. It\n     includes an RCU head like the keyring payload and for the same reason. It\n     also contains a data length because the data length in the key may be\n     changed on another CPU whilst an RCU protected read is in progress on the\n     payload. This would then see the supposed RCU payload and the on-key data\n     length getting out of sync.\n\n     I\u0027m tempted to drop the key\u0027s datalen entirely, except that it\u0027s used in\n     conjunction with quota management and so is a little tricky to get rid\n     of.\n\n (6) Update the keys documentation.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
