* Correct oggpack_writecopy bug reported by Ian Nartowicz: IntegerMonty2014-04-241-15/+246
| | | | | | | | | | | | | | | | overflow checking in oggpack_writecopy_helper got the reallocation size test condition backwards and so would error out when it needed to expand the destination's internal buffer. At the same time, do preexpansion of both aligned and unaligned copies to avoid possible heap thrashing in the unaligned case. Add black and glass box unit tests for oggpack_writecopy and oggpackB_writecopy. git-svn-id: http://svn.xiph.org/trunk/ogg@19119 0101bb08-14d6-0310-b084-bc0e0c8e3800

* Two cleanups of buffer LONG_MAX overflow hardening:Monty2010-06-041-3/+3
| | | | | | | | | | | | GCC optimizes out the overflow check due to the overflow check reyling on overflow; reimplement using type-based TYPE_MAX macro Correct an accidental assignment-during-check that wasn't a bug, but was semantically incorrect and rightly triggered a compilation warning. git-svn-id: http://svn.xiph.org/trunk/ogg@17270 0101bb08-14d6-0310-b084-bc0e0c8e3800
* Complete code review on the pattern:Monty2010-06-041-56/+90
| | | | | | | | | | | | | | if(b->endbyte*8+bits>b->storage*8)goto overflow; Eliminate the possibility of b->endbyte overflow on buffer storage near or exactly at long storage limit; corrections made to both read and write. Also, harden both read and write against requesting <0 or >32 read/write. In both case, the packer is put into 'error' state. git-svn-id: http://svn.xiph.org/trunk/ogg@17268 0101bb08-14d6-0310-b084-bc0e0c8e3800
* Cast away a char pointer signedness warning.Ralph Giles2010-03-261-4/+4
| | | | | | | | | | | The oggpack_* calls expect an unsigned char *, but the self-test code for convenience uses string literals for some of the test vectors. This generates a warning on gcc and clang, at least. We silence the warning by casting the literals to (unsigned char *). git-svn-id: http://svn.xiph.org/trunk/ogg@17063 0101bb08-14d6-0310-b084-bc0e0c8e3800
* Modify default page flushing behavior;Monty2010-03-211-2/+2
| | | | | | | | | | | 1) Don't unneccessarily span pages. 2) Unless necessary, don't flush pages if there are less than four packets on them; this expands page size to reduce unneccessary overhead if incoming packets are large. git-svn-id: http://svn.xiph.org/trunk/ogg@16993 0101bb08-14d6-0310-b084-bc0e0c8e3800

| | | | | | | | | | | | | | | | | | | | so much, autofoo) Update ogg to check the return of all allocs for those on embedded platforms with guarantees non-ovecommit. Be aware that these checks are useless on any modern desktop OS, but that embedded folks with no MMU and a hard heap boundary will benefit. Add one new call to bitpacker that will query a write-mode oggpack_buffer to see if it ran out of memory at some point; there was no other way to add the error reporting in an ABI-compatible manner (and it also allows the writepacker to avoid extra checks; it will just keep going after running out of memory without faulting and state can be queried later). git-svn-id: http://svn.xiph.org/trunk/ogg@16016 0101bb08-14d6-0310-b084-bc0e0c8e3800
