Climbing evening.


This was quite simple training, I completed several old traverses, then couple of boulderings and starts, eventually after 2.5 hours Grange arrived, so at the end I tried one or two interesting traces, but my shoes are not supposed to anyhow help in climbing, so it was complex and I failed. For reference: my shoes.



And bigger photos: one and two.

I definitely need new pair...

Preliminary HIFN 795x (7955/7956) crypto accelerator chip driver for mainstream 2.6 tree.


I've just released a preliminary HIFN 795x driver for mainstream crypto api stack. Driver is based on my work for acrypto asynchronous crypto stack, where it worked correctly, but this one was only compile teted, since I do not have hardware right now. Will do all tests when it arrives.
I've sent to linux-crypto@ for comments mostly about cryptoapi bindings, since there are several issues (I was not agree with when Herbert designed them), which I might implement wrong in the driver.

Due to problems with interrupt storms and possible adapter freeze (sorry, but HIFN spec I have really sucks, so likely it is programming error, but who knows) I added special watchdog, which fires if after predefined timeout sessions which are supposed to be completed are not. In that case callback is invoked with -EBUSY error. Neither implementation I checked (OpenBSD, Linux OCF) does not support it, but it helped me greatly in acrypto days.

Patch is quite big (61k) and contains a lot of debug stuff, but it is only preliminary work.

So far, patch against 2.6.21 can be downloaded from archive.
