| * | malloc does not *need* to return page-aligned objects for size >= | otto | 2017-02-12 | 1 | -5/+2 | |
| | | | | | | a page. This is not required by any standard and other malloc implementation do not document (or implement) this. ok deraadt@ | |||||

| * | 1. When shrinking a chunk allocation, compare the size of the current | otto | 2017-01-21 | 1 | -46/+87 | |
| | | | | | | | | | | | allocation to the size of the new allocation (instead of the requested size). 2. Previously realloc takes the easy way and always reallocates if C is active. This commit fixes by carefully updating the recorded requested size in all cases, and writing the canary bytes in the proper location after reallocating. 3. Introduce defines to test if MALLOC_MOVE should be done and to compute the new value. | |||||
| * | Remove unnecessary casts of 'a' to char * since 'a' is already char *. | millert | 2017-01-04 | 1 | -10/+10 | |
| | | | | | | This is a remnant from the original 4.4BSD code that had 'a' as void * in the function args. No binary change. OK bluhm@ | |||||
| * | Eliminate some gcc warnings about 'unused variables', mostly by | krw | 2016-12-16 | 1 | -2/+2 | |

| * | CVE-2016-6559: fix potential buffer overflow(s) in link_ntoa(3). | millert | 2016-12-06 | 1 | -19/+35 | |
| | | | | | | | | A specially crafted struct sockaddr_dl argument can trigger a stack overflow of a static buffer in libc. An attacker may be able to use this to write to arbitrary locations in the data segment. From FreeBSD (glebius); OK deraadt@ mestre@ | |||||

| * | remove some old option letters and also make P non-settable. It has | otto | 2016-10-31 | 1 | -24/+6 | |
| | | | | | | been the default for ages, and I see no valid reason to be able to disable it. ok natano@ | |||||
| * | Pages in the malloc cache are either reused quickly or unmapped | otto | 2016-10-28 | 1 | -14/+1 | |
| | | | | | | | quickly. In both cases it does not make sense to set hints on them. So remove that option, which is just a remainder of old times when malloc used to hold on to pages. ok stefan@ | |||||

| * | Roll back uintptr_t cast changes after discussions with tedu, otto and | dtucker | 2016-10-16 | 3 | -24/+7 | |
| | | | | | | | | | | | | | | others. C11 6.5.6.9 says: When two pointers are subtracted, both shall point to elements of the same array object, or one past the last element of the array object; the result is the difference of the subscripts of the two array elements. In these cases the objects are arrays of char so the result is defined, and we believe that the report is based on a compiler incorrectly trapping on defined behaviour. | |||||
