      "message": "[PATCH] Keys: Add possessor permissions to keys [try #3]\n\nThe attached patch adds extra permission grants to keys for the possessor of a\nkey in addition to the owner, group and other permissions bits. 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. I\u0027ve also renamed the accessor functions to be more useful, and all\nreference variables should now end in \"_ref\".\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "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. This is\n     done with KEYCTL_SET_REQKEY_KEYRING and one of the KEY_REQKEY_DEFL_*\n     constants. The current setting can also be read using this call.\n\n (7) request_key() is partially interruptible. If it is waiting for another\n     process to finish constructing a key, it can be interrupted. This permits\n     a request-key cycle to be broken without recourse to rebooting.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-Off-By: Benoit Boissinot \u003cbenoit.boissinot@ens-lyon.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
