2006-05-31remove some silly casts. put spl calls after all declarations.Ted Unangst
put one splx in a better spot. make a variable size MALLOC use malloc. remove null test after malloc(M_WAITOK). add PR_NOWAIT flag to pool_get instead of 0. change callbacks to correct type. ok brad deraadt markus mickey

2006-03-21Implementation of the Michael MIC as defined in IEEE 802.11i for TKIP.Reyk Floeter
The MIC generates a weak 64bit digest protected by an additional key. Obviously, this digest alg is required for future IEEE 802.11i/WPA support. test vectors passed on alpha amd64 mvme68k mvme88k sgi sparc sparc64 vax i386 ok djm@

2004-12-21Don't use crypto thread for callbacks.Marco Pfatschbacher
This primarily improves IPsec performance when using crypto accelerators. With help from markus@, tested by wvdputte@. ok deraadt@, markus@

2004-06-20In crypto_thread(), always save return value from splimp(). We were onlyAaron Campbell
storing it once on kernel startup. Scary. "holy crap" --deraadt. art@ ok Unclear if this was actually a problem in practice, but this doesn't hurt.
2004-05-07Replace RSA-derived md5 code with code derived from Colin Plumb's PD version.Todd C. Miller
This moves md5.c out of libkern and into sys/crypto where it belongs (as requested by markus@). Note that md5.c is still mandatory (dev/rnd.c uses it). Verified with IPsec + hmac-md5 and tcp md5sig. OK henning@ and hshoexer@
2004-05-03Rev 1.4 was bogus (committed from the wrong tree), this repairs it.Todd C. Miller
2004-05-03some minor KNFTodd C. Miller
2004-04-29The data pointer passed to the transform function may not be properlyTodd C. Miller
aligned so copy it in a way that a) is endian indepenent and b) does not rely on alignment. Problem found and solution tested by hshoexer@
2004-04-28Sync userland sha2.c with kernel. The SHAXXX_End and SHAXXX_Data functionsTodd C. Miller
have been removed; we provide these in userland but not in the kernel.
2004-04-28Some KNF, made bit count u_int64_t instead of u_int32_t (similar to libc).Hans-Joerg Hoexer
Added constants for buffer lengths. ok millert@

2003-12-26- use 1/2 space for rijndael context in ipsecMarkus Friedl
- rijndael_set_key_enc_only() sets up context for encryption only - rijndael_set_key() always sets up full context - rijndaelKeySetupDec() gets back original protoype - uvm: use _enc_only() interface with hshoexer@, ok deraadt@

2003-09-23Replace select backends with poll backends. selscan() and pollscan()Todd C. Miller
now call the poll backend. With this change we implement greater poll(2) functionality instead of emulating it via the select backend. Adapted from NetBSD and including some changes from FreeBSD. Tested by many, deraadt@ OK
2003-09-03zap context correctly, from Juergen Buchmueller <pullmoll at stop1984 dot com>Federico G. Schwindt

2003-06-03license cleanup regarding term 4Theo de Raadt
2003-06-03Fastpath for userland crypto requests. This change makes userlandBob Beck
crypto requests attempt to call the crypto driver directly to process crypto layer requests, as opposed to queueing them in the kernel crypto thread. If we can't use the crypto devices (i.e. they're busy) we fall back to queueing the request up in the crypto thread as before. This does allow for faster performance in some cases (smaller requests, how small seems to be dependent on the card/cpu combination) where context switching is a major issue in performance. ok deraadt@ jason@
