| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes for the amalgamation generator for internal headers. Remove BOTAN_DLL exporting macros from all internal-only headers; the classes/functions there don't need to be exported, and avoiding the PIC/GOT indirection can be a big win. Add missing BOTAN_DLLs where necessary, mostly gfpmath and cvc For GCC, use -fvisibility=hidden and set BOTAN_DLL to the visibility __attribute__ to export those classes/functions.

| | | | | | | | | | | | | | QueryPerformanceCounter, into an entropy source hres_timer. Its results, if any, do not count as contributing entropy to the poll. Convert the other (monotonic/fixed epoch) timers to a single function get_nanoseconds_clock(), living in time.h, which statically chooses the 'best' timer type (clock_gettime, gettimeofday, std::clock, in that order depending on what is available). Add feature test macros for clock_gettime and gettimeofday. Remove the Timer class and timer.h. Remove the Timer& argument to the algorithm benchmark function.

* 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.

| | | | | | | | set to 1000 ms (scaling based on amount of data requested). At 1000 ms exactly, we would form a timeval of 0 seconds and 1000000 usecs (ie, 1 second). Linux was fine with this, but FreeBSD 7.0's select was returning EINVAL. Fix things to properly create the timeval so that everyone is happy.

| | | | | | | | | | | | | | | up during the Fedora submission review, that each source file include some text about the license. One handy Perl script later and each file now has the line Distributed under the terms of the Botan license after the copyright notices. While I was in there modifying every file anyway, I also stripped out the remainder of the block comments (lots of astericks before and after the text); this is stylistic thing I picked up when I was first learning C++ but in retrospect it is not a good style as the structure makes it harder to modify comments (with the result that comments become fewer, shorter and are less likely to be updated, which are not good things).

| * In es_unix, two changeslloyd2009-01-311-6/+3
| | | | | | | | | | | | | | | | | | | | | | Make the fast poll significantly more pessimistic/realistic about how many bits of randomness we're getting from getrusage and stat. Don't cut out from execing programs if the desired poll bits is under 128. Simply poll until either the accumulator says we're done or we run out of sources. Assumption is that the poll won't be run at all unless it is ncessary (es_unix comes late in the list of sources to use since it is pretty slow).

| * Change the max amount read from /dev/*random to 128 bits.lloyd2009-01-311-9/+4
| | | | | | | | | | | | Also, change the wait time to bits/16 milliseconds. For instance if 64 bits of entropy are requested, the reader will wait at most 4 ms in the select loop.
