It also has zero loops, a hang sounds odd.

But I add some printk's around the calls to sha_init and sha_transform. ... NET: Registered protocol family 2 extract_buf: call sha_init extract_buf: call sha_init done extract_buf: call sha_transform extract_buf: call sha_transform done extract_buf: call sha_transform extract_buf: call sha_transform done extract_buf: function exit These printk's come from drivers/char/random.c So it doesn't seem like it hangs in any of the sha_* funtions. But I never see any of the printk's I added to net/ipv4/syncookies.c or net/ipv4/tcp_output.c. btw, my compiler is: arm-angstrom-linux-gnueabi-gcc (GCC) 4.3.3 regards Joachim Eastwood > The biggest difference with the git sources is the slightly different > calling conventions (passing the workspace array as an argument is bad > for code generation, btw - since now gcc doesn't see that the > workspace accesses are dead) and the fact that the kernel version uses > kernel macros like "get_unaligned_be32()" rather than it's own > implementation. > > Linus > -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
