2016-11-10bplist: Prevent out-of-bounds read in plist_from_bin() when parsing offset_tableGravatar Filippo Bigarella1-1/+9
offset_table_index is read from the file, so we have full control over it. This means we can point offset_table essentially anywhere we want, which can lead to an out-of-bounds read when it will be used later on.

2016-09-19Change internal storage of PLIST_DATE values from struct timeval to doubleGravatar Nikias Bassen1-9/+2
This removes the timeval union member from the plist_data_t structure. Since struct timeval is 2x64bit on 64bit platforms this member unnecessarily grew the union size to 16 bytes while a size of 8 bytes is sufficient. Also, on 32bit platforms struct timeval is only 2x32bit of size, limiting the range of possible time values. In addition the binary property list format also stores PLIST_DATE nodes as double.
2016-05-12bplist: Speed up plist_to_bin conversion for large plistsGravatar Nikias Bassen1-4/+7
Using a better hashing algorithm and a larger hash table the conversion is A LOT faster when processing large plists. Thanks to Xiao Deng for reporting this issue and suggesting a fix.

2015-01-31bplist: Plug memory leaks caused by unused (and unfreed) bufferGravatar Nikias Bassen1-5/+0
When parsing binary plists with BPLIST_DICT or BPLIST_ARRAY nodes that are referenced multiple times in a particular file, a buffer was allocated that was not used, and also not freed, thus causing memory leaks.
2015-01-31bplist: Fix possible crash in plist_from_bin() caused by access to already ↵Gravatar Nikias Bassen1-3/+5
freed memory Given a specifically ordered binary plist the function plist_from_bin() would free BPLIST_DICT or BPLIST_ARRAY raw node data that is still required for parsing of following nodes. This commit addresses this issues by moving the memory free to the end of the parsing process.
2014-10-09bplist: Fix plist_from_bin() changing value nodes to key nodes in dictionariesGravatar Martin Szulecki1-11/+33
The parsing logic for binary dictionaries wrongly enforced the key type even on nodes that were already parsed as value nodes. This caused the resulting plist_t node tree to have key nodes instead of value nodes within dictionaries for some valid binary plists. This commit should also generally fixes parsing of binary plist files which use an efficient dictionary reference table.

2010-04-18Endianness, alignment and type-punning fixes for binary plist supportGravatar Julien BLACHE1-13/+63
- endianness issues: on big endian machines, writing out only part of an integer was broken (get_needed_bytes(x) < sizeof(x)) -> shift integer before memcpy() on big endian machines - alignment issues: unaligned reads when loading binary plist. Leads to slow runtime performance (kernel trapping and fixing things up), SIGBUS (kernel not helping us out) -> introduce get_unaligned() and have the compiler generate the code needed for the unaligned access (note that there remains unaligned accesses that I haven't been able to track down - I've seen 2 of them with test #2) - type-punning issues: breaking strict aliasing rules can lead to unexpected results as the compiler takes full advantage of the aliasing while optimizing -> introduce the plist_uint_ptr union instead of casting pointers Tested on amd64, alpha and hppa.
2010-03-24Fix armel floating point endianess (LP: #541879)Gravatar Alexander Sack1-6/+26
* on armel system floating poing data can have different endianess than rest of types; hence we fix arm endianess for defined(__VFP_FP__) to be big/native; this also applies for data parsing/writing * date parsing didnt flip the endianess back for little endian systems when reading the values causing test failures; we fix this by ensuring float endianess is applied when parsing
