* If MAP_NOSYNC is defined, pass it as a flag to mmap. Apparently onlloyd2008-07-171-1/+7
| | | | | | | | | | | | FreeBSD, by default the VM will sync dirty pages periodically, even if the pages do not need to be reclaimed. Since in this case the contents of the map will contain sensitive information, try to avoid that. The FreeBSD 7.0 man page for mmap also warns that severe file fragmentation can result from using MAP_NOSYNC with sparse files, which we are currently using. It recommends instead explicitly writing out zero bytes. Since typically the full range of pages in the file will be eventually accessed and modified, this doesn't seem like a problem.

| | | | | | | | | | | completely wrong, and it is rather disturbing I made that mistake. The poll() function will gather up to the number of bytes passed as its argument; it will do this by opening up files and reading up to 1024 bytes from each one. So we might open between 256 and 256*1024 files, depending on the sizes of them (ignoring empty files, which count for zero bytes). (Idea: also include the name of the file in the output? Is that useful?) Move the read_buf out of the loop to minimize allocator thrashing.

It is only used inside the entropy sources to provide some timing-dependent randomness. However, it is easier and basically 'as good' to treat the timers as entropy sources in their own right and feed their output directly into an entropy pool. This commit removes Library_State::system_clock and all calls to that function.

* | Provide a more flexible mechanism for specifying which modules are loaded.lloyd2007-03-1227-18/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | Now three classes are defined: 'request', 'auto', and 'asm_ok'. The 'auto' class is loaded automatically if the platform support matches up with what we are building for (this is the former default). The 'request' mode means it is only loaded if specifically requested by name. The 'asm_ok' module is marked for all modules that use any assembler (including inline assembler). This normally functions like 'auto', unless --debug is passed to configure, in which case it is treated as 'request'. Modules which do not specify a load behavior are given a default of 'request'.
