openbsd/src/lib/libc/stdlib, branch libressl-v2.5.1 A mirror of https://github.com/libressl/openbsd.git https://git.lua4.win/openbsd/atom?h=libressl-v2.5.1 2017-02-01T06:17:42+00:00 Let realloc handle and produce moved pointers for allocations between 2017-02-01T06:17:42+00:00 otto 2017-02-01T06:17:42+00:00 urn:sha1:3d904ce2ae6efe16909d9ba5fdc63559cd26653d half a page and a page. ok jmatthew@ tb@ 1. When shrinking a chunk allocation, compare the size of the current 2017-01-21T07:47:42+00:00 otto 2017-01-21T07:47:42+00:00 urn:sha1:9d0ad2ad94663962dbaafbd967e30ac985f4dc22 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 *. 2017-01-04T15:20:30+00:00 millert 2017-01-04T15:20:30+00:00 urn:sha1:da00babddfa64469738880736e1d616936cc2b95 This is a remnant from the original 4.4BSD code that had 'a' as void * in the function args. No binary change. OK bluhm@ MALLOC_STATS tweaks, by default not compiled in 2016-11-04T09:11:20+00:00 otto 2016-11-04T09:11:20+00:00 urn:sha1:bd4c083afb5f60bfa609d0dd4eee7ee3c830a0d2 small tweak to also check canaries if F is in effect 2016-11-03T18:51:49+00:00 otto 2016-11-03T18:51:49+00:00 urn:sha1:634ebace8103bf766f556cfe3aefdcdc5974a402 remove some old option letters and also make P non-settable. It has 2016-10-31T10:06:56+00:00 otto 2016-10-31T10:06:56+00:00 urn:sha1:1ac490ba8d947f0b9d1a81ea0a99a26b1ac19bba 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 2016-10-28T17:03:22+00:00 otto 2016-10-28T17:03:22+00:00 urn:sha1:ae9172c537046f015622e1416847e5a9240776c2 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@ $OpenBSD$ 2016-10-22T19:19:34+00:00 tb 2016-10-22T19:19:34+00:00 urn:sha1:ed59924354242d097021720d30f43572b5be54f7 - fix MALLOC_STATS compile 2016-10-22T14:27:19+00:00 otto 2016-10-22T14:27:19+00:00 urn:sha1:97d6ce5e637e147d155376f399497d44bdcbcf29 - redundant cast is redundant fix some void * arithmetic by casting 2016-10-21T15:39:31+00:00 otto 2016-10-21T15:39:31+00:00 urn:sha1:d5c49fe716c6907a14552832041ae3539e75d83a
