| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify ECB to use parallel encryption/decryption where possible Add toggles in build.h specifying how many blocks to process in parallel. Defaults to 8 blocks for all modes, which is sufficient that any likely parallelism can be extracted (via SIMD or concurrent execution) but not so much as to seem likely to cause cache problems (8*128 bits = 128 bytes, or two x86 cache lines)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | decryption. Currently only used for counter mode. Doesn't offer much advantage as-is (though might help slightly, in terms of cache effects), but allows for SIMD implementations to process multiple blocks in parallel when possible. Particularly thinking here of Serpent; TEA/XTEA also seem promising in this sense, as is Threefish once that is implemented as a standalone block cipher.

This was something that for whatever reason that I have long since forogotten was a good idea on IRIX running MIPS circa a decade ago, but was reported to cause problems on the Debian builds. Add mipsel as an alias for the mips32 architecture for Debian. The mips32 submodel names were badly typoed and did not work correctly. Remove the leading mips32- and mips64- from MIPS submodel names.

* Two changes to proc_walk:lloyd2009-07-251-2/+2
| | | | | | | | | | | | | | Don't read any file that is not world-readable. This avoids trouble when running as root, since on Linux various special files can cause odd interactions and/or blocking behavior when read (for instance /proc/kmsg). ssumption is that no such files are world-readable. This also avoids any issue of reading data that is potentially sensitive. Instead of reading the first 1 KB of each file, only read the first 128 bytes. This prevents large files (like /proc/config.gz or /proc/kallsyms) from swamping the input buffer; these inputs are pretty static and shouldn't count for much. Reducing to 128 bytes causes a poll to read about 400 different files, rather than ~30.
