Most architectures stores two copies of this buffer,\none for future reference and one for parameter parsing.\n\nCurrent kernel command-line size for most architecture is much too small for\nmodule parameters, video settings, initramfs paramters and much more. The\nproblem is that setting COMMAND_LINE_SIZE to a grater value, allocates static\nbuffers.\n\nIn order to allow a greater command-line size, these buffers should be\ndynamically allocated or marked as init disposable buffers, so unused memory\ncan be released.\n\nThis patch renames the static saved_command_line variable into\nboot_command_line adding __initdata attribute, so that it can be disposed\nafter initialization. This rename is required so applications that use\nsaved_command_line will not be affected by this change.\n\nIt reintroduces saved_command_line as dynamically allocated buffer to match\nthe data in boot_command_line.\n\nIt also mark secondary command-line buffer as __initdata, and copies it to\ndynamically allocated static_command_line buffer components may hold reference\nto it after initialization.\n\nThis patch is for linux-2.6.20-rc4-mm1 and is divided to target each\narchitecture. I could not check this in any architecture so please forgive me\nif I got it wrong.\n\nThe per-architecture modification is very simple, use boot_command_line in\nplace of saved_command_line.

This can take up a lot of extra disk space if the user\n creates a lot of small files. By storing the data in the extended\n attribute, each file will only occupy at least of 4KB of space.\n\n As the eCryptfs metadata set becomes larger with new features such as\n multi-key associations, most popular filesystems will not be able to store\n all of the information in the xattr region in some cases due to space\n constraints. However, the majority of users will only ever associate one\n key per file, so most users will be okay with storing their data in the\n xattr region.\n\n This option should be used with caution. I want to emphasize that the\n xattr must be maintained under all circumstances, or the file will be\n rendered permanently unrecoverable. The last thing I want is for a user to\n forget to set an xattr flag in a backup utility, only to later discover\n that their backups are worthless.\n\necryptfs_encrypted_view\n - When set, this option causes eCryptfs to present applications a\n view of encrypted files as if the cryptographic metadata were\n stored in the file header, whether the metadata is actually stored\n in the header or in the extended attributes.\n\n No matter what eCryptfs winds up doing in the lower filesystem, I want\n to preserve a baseline format compatibility for the encrypted files. As of\n right now, the metadata may be in the file header or in an xattr. There is\n no reason why the metadata could not be put in a separate file in future\n versions.\n\n Without the compatibility mode, backup utilities would have to know to\n back up the metadata file along with the files. The semantics of eCryptfs\n have always been that the lower files are self-contained units of encrypted\n data, and the only additional information required to decrypt any given\n eCryptfs file is the key. That is what has always been emphasized about\n eCryptfs lower files, and that is what users expect.

It\nmanages encryption/decryption request queues with a transport mechanism.\nCurrently, netlink is the only implemented transport.\n\nEach inode has a unique File Encryption Key (FEK). Under passphrase, a File\nEncryption Key Encryption Key (FEKEK) is generated from a salt/passphrase\ncombo on mount. This FEKEK encrypts each FEK and writes it into the header of\neach file using the packet format specified in RFC 2440. This is all\nsymmetric key encryption, so it can all be done via the kernel crypto API.\n\nThese new patches introduce public key encryption of the FEK. There is no\nasymmetric key encryption support in the kernel crypto API, so eCryptfs pushes\nthe FEK encryption and decryption out to a userspace daemon. After\nconsidering our requirements and determining the complexity of using various\ntransport mechanisms, we settled on netlink for this communication.\n\neCryptfs stores authentication tokens into the kernel keyring. These tokens\ncorrelate with individual keys. For passphrase mode of operation, the\nauthentication token contains the symmetric FEKEK. For public key, the\nauthentication token contains a PKI type and an opaque data blob managed by\nindividual PKI modules in userspace.\n\nEach user who opens a file under an eCryptfs partition mounted in public key\nmode must be running a daemon. That daemon has the user\u0027s credentials and has\naccess to all of the keys to which the user should have access. The daemon,\nwhen started, initializes the pluggable PKI modules available on the system\nand registers itself with the eCryptfs kernel module. Userspace utilities\nregister public key authentication tokens into the user session keyring.\nThese authentication tokens correlate key signatures with PKI modules and PKI\nblobs. The PKI blobs contain PKI-specific information necessary for the PKI\nmodule to carry out asymmetric key encryption and decryption.\n\nWhen the eCryptfs module parses the header of an existing file and finds a Tag\n1 (Public Key) packet (see RFC 2440), it reads in the public key identifier\n(signature). The asymmetrically encrypted FEK is in the Tag 1 packet;\neCryptfs puts together a decrypt request packet containing the signature and\nthe encrypted FEK, then it passes it to the daemon registered for the\ncurrent-\u003eeuid via a netlink unicast to the PID of the daemon, which was\nregistered at the time the daemon was started by the user.\n\nThe daemon actually just makes calls to libecryptfs, which implements request\npacket parsing and manages PKI modules. libecryptfs grabs the public key\nauthentication token for the given signature from the user session keyring.\nThis auth tok tells libecryptfs which PKI module should receive the request.\nlibecryptfs then makes a decrypt() call to the PKI module, and it passes along\nthe PKI block from the auth tok. The PKI uses the blob to figure out how it\nshould decrypt the data passed to it; it performs the decryption and passes\nthe decrypted data back to libecryptfs. libecryptfs then puts together a\nreply packet with the decrypted FEK and passes that back to the eCryptfs\nmodule.\n\nThe eCryptfs module manages these request callouts to userspace code via\nmessage context structs. The module maintains an array of message context\nstructs and places the elements of the array on two lists: a free and an\nallocated list. When eCryptfs wants to make a request, it moves a msg ctx\nfrom the free list to the allocated list, sets its state to pending, and fires\noff the message to the user\u0027s registered daemon.\n\nWhen eCryptfs receives a netlink message (via the callback), it correlates the\nmsg ctx struct in the alloc list with the data in the message itself. The\nmsg-\u003eindex contains the offset of the array of msg ctx structs. It verifies\nthat the registered daemon PID is the same as the PID of the process that sent\nthe message. It also validates a sequence number between the received packet\nand the msg ctx. Then, it copies the contents of the message (the reply\npacket) into the msg ctx struct, sets the state in the msg ctx to done, and\nwakes up the process that was sleeping while waiting for the reply.\n\nThe sleeping process was whatever was performing the sys_open(). This process\noriginally called ecryptfs_send_message(); it is now in\necryptfs_wait_for_response(). When it wakes up and sees that the msg ctx\nstate was set to done, it returns a pointer to the message contents (the reply\npacket) and returns. If all went well, this packet contains the decrypted\nFEK, which is then copied into the crypt_stat struct, and life continues as\nnormal.\n\nThe case for creation of a new file is very similar, only instead of a decrypt\nrequest, eCryptfs sends out an encrypt request.\n\n\u003e - We have a great clod of key mangement code in-kernel. Why is that\n\u003e not suitable (or growable) for public key management?\n\neCryptfs uses Howells\u0027 keyring to store persistent key data and PKI state\ninformation. It defers public key cryptographic transformations to userspace\ncode. The userspace data manipulation request really is orthogonal to key\nmanagement in and of itself. What eCryptfs basically needs is a secure way to\ncommunicate with a particular daemon for a particular task doing a syscall,\nbased on the UID. Nothing running under another UID should be able to access\nthat channel of communication.\n\n\u003e - Is it appropriate that new infrastructure for public key\n\u003e management be private to a particular fs?\n\nThe messaging.c file contains a lot of code that, perhaps, could be extracted\ninto a separate kernel service. In essence, this would be a sort of\nrequest/reply mechanism that would involve a userspace daemon. I am not aware\nof anything that does quite what eCryptfs does, so I was not aware of any\nexisting tools to do just what we wanted.\n\n\u003e What happens if one of these daemons exits without sending a quit\n\u003e message?\n\nThere is a stale uid\u003c-\u003epid association in the hash table for that user. When\nthe user registers a new daemon, eCryptfs cleans up the old association and\ngenerates a new one. See ecryptfs_process_helo().\n\n\u003e - _why_ does it use netlink?\n\nNetlink provides the transport mechanism that would minimize the complexity of\nthe implementation, given that we can have multiple daemons (one per user). I\nexplored the possibility of using relayfs, but that would involve having to\nintroduce control channels and a protocol for creating and tearing down\nchannels for the daemons. We do not have to worry about any of that with\nnetlink.\n\nSigned-off-by: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b5d5dfbd59577aed72263f22e28d3eaf98e1c6e5", "tree": "9ef320c6ff4f61bffb25c0452570d5f76ab7769c", "parents": [ "77f1f67a1a56defa210c3d8857f3e5eee3990a99" ], "author": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Mon Feb 12 00:53:40 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon Feb 12 09:48:36 2007 -0800" }, "message": "[PATCH] include/linux/nfsd/const.h: remove NFS_SUPER_MAGIC\n\nNFS_SUPER_MAGIC is already defined in include/linux/magic.h\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\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": "77f1f67a1a56defa210c3d8857f3e5eee3990a99", "tree": "9d34af393db31a566c01f915074ff070c644ecc1", "parents": [ "95756482c9bfa375418c5a32455494a3042f65cd" ], "author": { "name": "Chuck Lever", "email": "chuck.lever@oracle.com", "time": "Mon Feb 12 00:53:39 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon Feb 12 09:48:36 2007 -0800" }, "message": "[PATCH] knfsd: SUNRPC: fix up svc_create_socket() to take a sockaddr struct + length\n\nReplace existing svc_create_socket() API to allow callers to pass addresses\nlarger than a sockaddr_in.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nCc: Aurelien Charbon \u003caurelien.charbon@ext.bull.net\u003e\nSigned-off-by: 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": "95756482c9bfa375418c5a32455494a3042f65cd", "tree": "1c7583a43df17591cae77af601143509ab68c2b1", "parents": [ "cdd88b9f3ed5013de0f1085e0e2f9123c798609d" ], "author": { "name": "Chuck Lever", "email": "chuck.lever@oracle.com", "time": "Mon Feb 12 00:53:38 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon Feb 12 09:48:36 2007 -0800" }, "message": "[PATCH] knfsd: SUNRPC: support IPv6 addresses in RPC server\u0027s UDP receive path\n\nAdd support for IPv6 addresses in the RPC server\u0027s UDP receive path.\n\n[akpm@linux-foundation.org: cleanups]\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nCc: Aurelien Charbon \u003caurelien.charbon@ext.bull.net\u003e\nSigned-off-by: 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": "cdd88b9f3ed5013de0f1085e0e2f9123c798609d", "tree": "2e2fba732f54c487461ad0da81bc8f11daea2786", "parents": [ "bcdb81ae29091f6a66369aabfd8324e4a53d05dc" ], "author": { "name": "akpm@linux-foundation.org", "email": "akpm@linux-foundation.org", "time": "Mon Feb 12 00:53:38 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon Feb 12 09:48:36 2007 -0800" }, "message": "[PATCH] knfsd: SUNRPC: Support IPv6 addresses in svc_tcp_accept\n\nModify svc_tcp_accept to support connecting on IPv6 sockets.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nCc: Aurelien Charbon \u003caurelien.charbon@ext.bull.net\u003e\nSigned-off-by: 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": "bcdb81ae29091f6a66369aabfd8324e4a53d05dc", "tree": "ce70eed085bd56c0b1eaffa838ca27bec94e1345", "parents": [ "b92503b25c3f794cff5f96626ea3ecba8d10d254" ], "author": { "name": "Chuck Lever", "email": "chuck.lever@oracle.com", "time": "Mon Feb 12 00:53:37 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon Feb 12 09:48:36 2007 -0800" }, "message": "[PATCH] knfsd: SUNRPC: add a \"generic\" function to see if the peer uses a secure port\n\nThe only reason svcsock.c looks at a sockaddr\u0027s port is to check whether the\nremote peer is connecting from a privileged port.
