574b1bb8a5 Quick fix for wrong mmap data size calculation. 
This patch addresses #16 but needs more work and a regression test
before the issue can be closed.

418fae2ab6 Do not use rand() within fseek(), it might break reproducibility. 2016-05-03 08:05:14 +02:00

e413984095 Work around an issue with fseek() diversion. Closes #7. 
When diverting functions that handle FILE objects, we try to detect whether
the internal buffer contents have changed and therefore need to be fuzzed.
In recent glibc versions, it may happen that an fseek() call is made that
should not invalidate the internal buffer, yet a read() call is still performed.

This is arguably a bug. Considering the following code:

    f = fopen("/dev/null", "r");
    fread(ptr, 1, 1, f);
    fseek(f, 1, SEEK_SET);

The following system calls are made, where the second read() call is
completely unnecessary and is the cause for the buffer refill:

    read(..., 4096);
    lseek(0, SEEK_SET);
    read(..., 4096);

In order to work around this problem, we fill the internal buffer with random
data before calling fseek(), we check whether any bytes have changed, then we
restore it if it was left untouched. This is not 100% robust but honestly it
will do for now.

6ccb82a9ff stream: fix a nasty bug that completely messed up with the streambuf 
structure tracking. Now when the new streambuf position is exactly at
the end of the previous streambuf, we only fuzz the streambuf if new
data is available (i.e. when streambuf_count != 0); otherwise, it just
means that we’re at the end of the file, waiting for new read orders.
