2008-07-21Add curproc to ioctl call.Marco Peereboom
Noticed by todd, proded by miod.
2008-07-20fill in variant and version components of the UUIDDamien Miller
pretty-print the UUID in RFC4122 form
2008-07-19Full rewrite of metadata handling. This fixes power failures and crashesMarco Peereboom
that caused illegal checksums. The new metadata code is more or less ready to deal with other vendor's metadata formats. While here clean up the name space. Fix thib's pool mess by adding removing bad flags in interrupt context. tested on macppc, amd64, i386, sparc64 & hppa sparc64 has issues with crypto however those do not seem to be softraid specific. help from okan@ ckuethe@ Will Backman and others
2008-06-25use pools for the uio and iovec allocations in sr_crypto_getcryptop()Thordur I. Bjornsson
instead of malloc; OK hshoexer@ and macro@
2008-06-14Provide a status field for operations on the bc_opaque data. Now we'reHans-Joerg Hoexer
able to distinguish cleanly an failing ioctl (ie. return value -1) from trying to retrieve a KDF hint from a not yet initialized volume. ok marco djm
2008-06-14Update bioctl(8) and softraid(4) to recent changes and enable softraidHans-Joerg Hoexer
crypto. It's still considered experimental! ok djm marco
2008-06-13When assembling an already initialized crytpo softraid, correctly copy inHans-Joerg Hoexer
mask key from userland. Thus, modify sr_crypto_get_kdf() do correclty handle copying kdf hint and/or mask key. While there, remove superflous sr_read_meta(). ok marco djm
2008-06-12make sure to check that a crypto volume is not yet assembled whenHans-Joerg Hoexer
retrieving the kdf blobb. Pointed out by marco. while there, use %lld instead of %d when printing b_blkno, which daddr64_t. ok marco
2008-06-12Clead discipline pointer after delete. Found by hshoexerMarco Peereboom
2008-06-12Get mask keying for on-disk keys from user space and keep a "hint" for keyHans-Joerg Hoexer
generation used by user space in the meta data. Actually use the masking key for encryption and decryption of on-disk key at run time. ok djm marco

disabled, of course, and still work in progress. help by djm@, ok marco@

2008-02-07Add optional metadata memebers.Marco Peereboom
Randomize Crypto password and add salt array. Add mock key encryption functions.
2008-02-05Shave off a few more bytes by moving IO collision detection into a genericMarco Peereboom
fucntion. Fix bug in the crypto code that could casuse data corruption as a bonus, bad cut & past tedu!
2008-02-05Add strip size to debug print.Marco Peereboom
2008-02-05Create a generic function to validate IO instead of copying and pastingMarco Peereboom
same code in all disciplines. This shaves of a few bytes. crypto 3185 -> 2690 raid 0 2843 -> 2378 raid 1 3474 -> 2689
2008-02-03There is no such thing as RAIDCRYPTO so rename to CRYPTOMarco Peereboom
2008-01-29Improve performance dramatically by preventing severeal context switches.Marco Peereboom
Decrypt only once on entry or exit instead of on in and out regardless of direction. There is still room for improvement but this is the first stab. Tested by many ok tedu
2008-01-24Create chunk and state transition functions for RAID 0.Marco Peereboom
Move RAID 1 chunk and state transition functions into proper file. Let Crypto use RAID 1 chunk and state transition functions for now but this needs fixing.
2008-01-24Bring softraid into the world of 16 byte commands; this allows for > 2TB disksMarco Peereboom
Fix bioctl size output which was off by *512; diagnosed by otto

kernel thread of its own. the api has changed (which will be fixed in the manpage shortly) so all the users of sensor tasks that i can find have been fixed too. noone tested, so its going in to force people to run with it. "put it in" deraadt@

2007-06-05Shuffle calculation of physical block so that bounds checking is not off byMarco Peereboom
48 blocks (metadata + metdata offset). Found by drahn. Fix panic message while in the same area. Help from otto who wrote a diff that worked around the issue. ok deraadt

2007-06-03virtual device drivers tend not to need machine/bus.h. also importantTheo de Raadt
because mvme68k (and perhaps others) do not have it. showed it to dlg who just shook his head
2007-06-03During autoassemble get the actual raid level instead of always 1.Marco Peereboom
Sprinkle debug throughout crypto discipline. Various knf, bad tedu!

only tedu understands.
2007-06-02Fix collision by not adding data length but blocks instead.Marco Peereboom
Some clean up.
