If the user enables filename encryption, the mount helper will\nthen prompt for the FNEK signature that the user wishes to use, suggesting\nby default the signature for the mount passphrase that the user has\nalready entered for encrypting the file contents.\n\nWhen not using the mount helper, the user can specify the signature for\nthe passphrase key with the ecryptfs_fnek_sig\u003d mount option. This key\nmust be available in the user\u0027s keyring. The mount helper usually takes\ncare of this step. If, however, the user is not mounting with the mount\nhelper, then he will need to enter the passphrase key into his keyring\nwith some other utility prior to mounting, such as ecryptfs-manager.\n\nSigned-off-by: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nCc: Dustin Kirkland \u003cdustin.kirkland@gmail.com\u003e\nCc: Eric Sandeen \u003csandeen@redhat.com\u003e\nCc: Tyler Hicks \u003ctchicks@us.ibm.com\u003e\nCc: David Kleikamp \u003cshaggy@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "addd65ad8d19a7d7982130b16f957d5d01d3f8df", "tree": "2263b4a4b7a6269410bd161a3995d2b4af3f7bcf", "parents": [ "51ca58dcc9f0d6b1e78954d08bd4954fb6a1421c" ], "author": { "name": "Michael Halcrow", "email": "mhalcrow@us.ibm.com", "time": "Tue Jan 06 14:42:00 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 06 15:59:22 2009 -0800" }, "message": "eCryptfs: Filename Encryption: filldir, lookup, and readlink\n\nMake the requisite modifications to ecryptfs_filldir(), ecryptfs_lookup(),\nand ecryptfs_readlink() to call out to filename encryption functions.\nPropagate filename encryption policy flags from mount-wide crypt_stat to\ninode crypt_stat.\n\nSigned-off-by: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nCc: Dustin Kirkland \u003cdustin.kirkland@gmail.com\u003e\nCc: Eric Sandeen \u003csandeen@redhat.com\u003e\nCc: Tyler Hicks \u003ctchicks@us.ibm.com\u003e\nCc: David Kleikamp \u003cshaggy@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "51ca58dcc9f0d6b1e78954d08bd4954fb6a1421c", "tree": "0bd80a0a9322150527b2d2160d7b37d0e067f389", "parents": [ "a34f60f748c6fe5d791e9b54cffe442201428254" ], "author": { "name": "Michael Halcrow", "email": "mhalcrow@us.ibm.com", "time": "Tue Jan 06 14:41:59 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 06 15:59:21 2009 -0800" }, "message": "eCryptfs: Filename Encryption: Encoding and encryption functions\n\nThese functions support encrypting and encoding the filename contents.\nThe encrypted filename contents may consist of any ASCII characters.

When eCryptfs encounters this prefix, it\ndecodes the filename into a tag 70 packet and then decrypts the packet\ncontents using the FNEK, setting the filename to the decrypted filename.\nBoth unencrypted and encrypted filenames can reside in the same lower\nfilesystem.\n\nBecause filename encryption expands the length of the filename during the\nencoding stage, eCryptfs will not properly handle filenames that are\nalready near the maximum filename length.\n\nIn the present implementation, eCryptfs must be able to produce a match\nagainst the lower encrypted and encoded filename representation when given\na plaintext filename. Therefore, two files having the same plaintext name\nwill encrypt and encode into the same lower filename if they are both\nencrypted using the same FNEK. This can be changed by finding a way to\nreplace the prepended bytes in the blocked-aligned filename with random\ncharacters; they are hashes of the FNEK right now, so that it is possible\nto deterministically map from a plaintext filename to an encrypted and\nencoded filename in the lower filesystem. An implementation using random\ncharacters will have to decode and decrypt every single directory entry in\nany given directory any time an event occurs wherein the VFS needs to\ndetermine whether a particular file exists in the lower directory and the\ndecrypted and decoded filenames have not yet been extracted for that\ndirectory.\n\nThanks to Tyler Hicks and David Kleikamp for assistance in the development\nof this patchset.\n\nThis patch:\n\nA tag 70 packet contains a filename encrypted with a Filename Encryption\nKey (FNEK).

If this operation is repeated many times, it can be very\nexpensive. It would be much nicer if the operation could be performed\nonce before a buffer goes to disk.\n\nThis adds triggers to jbd2 buffer heads. Just before writing a metadata\nbuffer to the journal, jbd2 will optionally call a commit trigger associated\nwith the buffer. If the journal is aborted, an abort trigger will be\ncalled on any dirty buffers as they are dropped from pending\ntransactions.\n\nocfs2 will use this feature.\n\nInitially I tried to come up with a more generic trigger that could be\nused for non-buffer-related events like transaction completion. It\ndoesn\u0027t tie nicely, because the information a buffer trigger needs\n(specific to a journal_head) isn\u0027t the same as what a transaction\ntrigger needs (specific to a tranaction_t or perhaps journal_t). So I\nimplemented a buffer set, with the understanding that\njournal/transaction wide triggers should be implemented separately.\n\nThere is only one trigger set allowed per buffer. I can\u0027t think of any\nreason to attach more than one set. Contrast this with a journal or\ntransaction in which multiple places may want to watch the entire\ntransaction separately.\n\nThe trigger sets are considered static allocation from the jbd2\nperspective. ocfs2 will just have one trigger set per block type,\nsetting the same set on every bh of the same type.\n\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\nCc: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n" }, { "commit": "754938c142ae0c28360426c43f965ddc5164b21e", "tree": "e2c764f7868c91ab8e39f56d29951480dbf468e7", "parents": [ "91f2033fa997aa92607470ed1ef90685b9d77a8c" ], "author": { "name": "Tao Ma", "email": "tao.ma@oracle.com", "time": "Mon Dec 15 06:03:41 2008 +0800" }, "committer": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Mon Jan 05 08:40:30 2009 -0800" }, "message": "ocfs2/quota: Add QUOTA in mlog_attribute.\n\nA new mlog mask has to be added into mlog_attribute before it can\nbe really used in mlog.
