| * | 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@ | |||||

| * | Long ago, malloc internally had two kinds of failures, warnings and errors. | tedu | 2016-01-06 | 1 | -8/+4 | |
| | | | | | | | | | The 'A' option elevated warnings to errors, and has been the default for some time. Then warnings were effectively eliminated in favor of everything being an error, but then the 'a' flag turned real errors into warnings! Remove the 'a' option entirely. You shouldn't have used it anyway. ok tb tdeval | |||||

| * | Integrate two patches originally from Daniel Micay. | tedu | 2015-12-09 | 1 | -8/+76 | |
| | | | | | | | | | | | | | 1. Optionally add random "canaries" to the end of an allocation. This requires increasing the internal size of the allocation slightly, which probably results in a large effective increase with current power of two sizing. Therefore, this option is only enabled via 'C'. 2. When writing junk (0xdf) to freed chunks (current default behavior), check that the junk is still intact when finally freeing the delayed chunk to catch some potential use after free. This should be pretty cheap so there's no option to control it separately. ok deraadt tb | |||||

| * | improve realloc. when expanding a region, actually use the free page cache | tedu | 2015-04-06 | 1 | -7/+16 | |
| | | | | | | instead of simply zapping it. this can save many syscalls in a program that repeatedly grows and shrinks a buffer, as observed in the wild. | |||||

| | | | | | | | | to hold the malloc lock across mmap syscalls in all cases. dropping it allows another thread to access the existing chunk cache if necessary. could be improved to be a bit more aggressive, but i've been testing this simple diff for some time now with good results. | |||||
