3 | _FP_gets still 70% of scan time. decode time: 24% _FP_gets, uulib_crc32 23%, UUValidData 11% |
|

|
|
5 | - include ecb.h to deal with compiler builtins and endianness. |
|
|
6 | - replace crc32 function by slice-by-16 version by Stephan Brumme, |
|
|
7 | which should speed up yEnc en-/decoding. |
|
|
8 | - some further µ-optimisations in hot code, especially for yEnc. |
|
|
9 | - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as |
|
|
10 | some draft mentions both and it is actually in active use. |
|
|
11 | - yEnc: ignore crc32= on multiparts, except on the last part. |
|
|
12 | - be more precise in documenting code licenses in COPYING. |

|
|
15 | - major performance improvement by simplifying code in _FP_gets |
|
|
16 | to not use fscanf. This might slow things down on platforms |
|
|
17 | with very slow fgetc. |

|
20 | - lint uulib: fix some format string type mismatches |
|
|
21 | and some other minor issues. |

|
|
24 | - fix heap overflow (testcase by Noel Duffy, reported |
|
|
25 | by Robert Scheck). The defense-in-depth mechanism based |
|
|
26 | on mmap should make this unexploitable for other than denial |
|
|
27 | of service, on systems supporting mmap/mprotect. |

|
|
30 | - fix a heap overflow (testcase by Krzysztof Wojtaś). |
|
|
31 | - on systems that support it (posix + mmap + map_anonymous), |
|
|
32 | allocate all dynamic areas via mmap and put four guard |
|
|
33 | pages around them, to catch similar heap overflows |
|
|
34 | safely in the future. |
|
|
35 | - find a safer way to pass in CC/CFLAGS to uulib. |
|
|
36 | - added stability canary support. |
