It's possible to define .configs in which there are no references in vmlinux to lib/parser.o. So you cannot load any filesystem modules. Arrange for parser.o to be statically linked. Signed-off-by:

Move half-MD4 hash to /lib where we can share it with htree. Signed-off-by:

Drop the cryptolib SHA implementation and use the faster and much smaller SHA implementation from lib/. Saves about 5K. This also saves time by doing one memset per update call rather than one per SHA block. Signed-off-by:

A replacement SHA routine that's slightly larger, but over twice as fast. It's also faster and much smaller than the cryptolib version. size speed buffer size original: 350B 2.3us 320B cryptolib: 5776B 1.2us 80B this code: 466B 1.0us 320B alternate: 2112B 1.0us 80B Signed-off-by: -

Kill the unrolled SHA variants, they're unused and duplicate code in cryptoapi. Signed-off-by:

Move users of private rotl/rotr functions to rol32/ror32. Crypto bits verified with tcrypt. Signed-off-by:

Rather than batching up entropy samples, resulting in longer lock hold times when we actually process the samples, mix in samples immediately. The trickle code should eliminate almost all the additional interrupt-time overhead this would otherwise incur, with or without locking. Signed-off-by:

Clean up buffer usage for SHA and reseed. This makes the code more readable and reduces worst-case stack usage. Signed-off-by:

Break apart extract_entropy into kernel and user versions, remove last extract flag and some unnecessary variables. This makes the code more readable and amenable to sparse. Signed-off-by:
-
Matt Mackall authored
Put pointer to reseed pool in pool struct and automatically pull entropy from it if it is set. This lets us remove the EXTRACT_SECONDARY flag. Signed-off-by:
-
Matt Mackall authored
Move the limit flag to the pool struct, begin process of eliminating extract flags. Signed-off-by:
-
Matt Mackall authored
Additional parameter to allow keeping an entropy reserve in the input pool. Groundwork for proper /dev/urandom vs /dev/random starvation prevention. Signed-off-by:
-
Matt Mackall authored
When reseeding, we must always do a "catastrophic reseed" where we pull enough new bits to make the new state unguessable from outputs even if we knew the old state. So we must do the checks against the minimum reseed amount under the pool lock in extract_entropy. Signed-off-by:

Static initialization for sysctl support Signed-off-by:
-
Matt Mackall authored
As we no longer allow resizing of pools, it makes sense to allocate and initialize them statically. Remove create_entropy_store and simplify rand_initialize. Signed-off-by:

Matt Mackall authored
Give pools more meaningful names. Signed-off-by:

Remove incorrectly named ln (it's log2!) and x86 asm function and replace with fls bitop. Signed-off-by:

Matt Mackall authored
This thinko.. makes things a bit more arbitrary than we'd like. I've re-audited the other rotate conversions. Signed-off-by:
-
Matt Mackall authored
We've got three definitions of rotate_left. Remove x86 and duplicate rotate definitions. Remaining definition is fixed up such that recent gcc will generate rol instructions on x86 at least. A later patch will move this to bitops and clean up the other tree users. Signed-off-by:

Matt Mackall authored
Remove Linux 2.2 compatibility cruft. Signed-off-by:
-
Matt Mackall authored
Remove unused extract_timer_state struct. It was formerly used to feedback zero-entropy timing samples while extracting entropy, but that had a tendency to overwhelm the batch processing queue and prevent storing real samples. Signed-off-by:

ZAPENTCNT is now effectively identical to RNDCLEARPOOL, fall through Signed-off-by:
-
Matt Mackall authored
Remove pool clearing. We've only ever cleared one of three pools and there's no good reason to do it. Instead just reset the entropy count. Signed-off-by:
-
Matt Mackall authored
Original code checked in output pool for missed wakeup avoidance, while waker (batch_entropy_process) checked input pool which could result in a missed wakeup. - Move to wait_event_interruptible style - Delete superfluous waitqueue Signed-off-by:

x86_64 wasn't doing anything special in its sort_extable. Use the generic lib/extable sort. Signed-off-by:
