2017-01-21	Nuke whitespace foolish enough to expose itself during the great	Kenneth R Westerback
	"warning:" rectification.
2017-01-21	1. When shrinking a chunk allocation, compare the size of the current	Otto Moerbeek
	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.
2017-01-11	Add support for AArch64.	Patrick Wildt

2017-01-04	Remove unnecessary casts of 'a' to char * since 'a' is already char *.	Todd C. Miller
	This is a remnant from the original 4.4BSD code that had 'a' as void * in the function args. No binary change. OK bluhm@
2016-12-25	gcc says "if you define labels and don't use them, I will whine."	Kenneth R Westerback
	ok tom@
2016-12-22	Clarify code by eliminating unused #define's MUSTSEE, MUSTNOTSEE and inlining	Kenneth R Westerback
	MUSTEAT. ok tom@
2016-12-21	Adopt relevant part of NetBSD's r1.7 commit to discard unused results of the	Kenneth R Westerback
	expressions generated by the REQUIRE() macro. Thus eliminating from build output 100 lines or so of gcc complaints about "computed but not used". cluebat & ok tom@
2016-12-20	Add 'default:' cases to switch statements that gcc whines about.	Kenneth R Westerback
	ok jung@
2016-12-18	Another whitespace nit that wandered into my sights.	Kenneth R Westerback

2016-12-18	Remove prototype for static function _asr_resolver. Eliminates gcc	Kenneth R Westerback
	whining about undefined static in all the .c files that include asr_private.h. _asr_resolver() is defined and used in asr.c only. ok kettenis@
2016-12-16	Eliminate some gcc warnings about 'unused variables', mostly by	Kenneth R Westerback
	adding appropriate #ifdef's around declarations. ok millert@ (with a tweak I will commit separately)
2016-12-15	Nuke some trailing tabs.	Kenneth R Westerback

2016-12-08	Fix regressions introduce in the fix for CVE-2016-6559.	Todd C. Miller
	From FreeBSD (glebius)
2016-12-07	Fix a typo, decrement rem, don't increment for single digit hex bytes.	Todd C. Miller
	From Henri Kemppainen
2016-12-06	CVE-2016-6559: fix potential buffer overflow(s) in link_ntoa(3).	Todd C. Miller
	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@
2016-11-12	the referred to EXAMPLES section is now in strncpy(3);	Jason McIntyre
	issue reported by scott cheloha ok otto
2016-11-09	Fix a use after free error introduced in rev 1.18 by only calling	Todd C. Miller
	closedir() outside the loop. OK deraadt@ guenther@ markus@
2016-11-04	MALLOC_STATS tweaks, by default not compiled in	Otto Moerbeek

2016-11-03	small tweak to also check canaries if F is in effect	Otto Moerbeek

2016-10-31	remove some old option letters and also make P non-settable. It has	Otto Moerbeek
	been the default for ages, and I see no valid reason to be able to disable it. ok natano@
2016-10-30	include float.h for the LDBL_MAX_EXP cpp test in floatio.h	Jonathan Gray

2016-10-28	Pages in the malloc cache are either reused quickly or unmapped	Otto Moerbeek
	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@
2016-10-27	For consistency, allow symlinkat(2) in the same way as symlink(2);	Ingo Schwarze
	no need to wait until the first program using it breaks... "could make sense" semarie@ (and thanks for the cluestick) OK deraadt@

2016-10-20	canary corruption message changed a bit	Otto Moerbeek

2016-10-20	Also place canaries in > page sized objects (if C is in effect); ok tb@	Otto Moerbeek

2016-10-19	Remove the save_errno dance inside strerror_r(3). It is from the	Alexander Bluhm
	time when we had national language support. OK millert@
2016-10-19	Use the reentrant strerror_r() instead of strerror() to expand %m.	Todd C. Miller
	Previously, syslog_r() would avoid calling strerror() since the latter is not reentrant. OK bluhm@
2016-10-19	note that SO_REUSEADDR is restricted to callers with the same uid or root;	Jason McIntyre
	while there, super-user -> superuser for internal consistency; diff from kirill miazine, tweaked by myself; ok deraadt millert guenther
2016-10-18	Avoid generate SIGTTOU when restoring the terminal mode. If we get	Todd C. Miller
	SIGTTOU it means the process is not in the foreground process group which, in most cases, means that the shell has taken control of the tty. Requiring the user the fg the process in this case doesn't make sense and can result in both SIGTSTP and SIGTTOU being sent which can lead to the process being suspended again immediately after being brought into the foreground.
2016-10-16	Roll back uintptr_t cast changes after discussions with tedu, otto and	Darren Tucker
	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.

2016-10-14	Cast pointers to uintptr_t to avoid potential signedness errors.	Darren Tucker

2016-10-07	introduce a sysctl to hijack dns sockets. when set to a port number,	Ted Unangst
	all dns socket connections will be redirected to localhost:port. this could be a sockopt on the listening socket, but sysctl is an easier interface to work with right now. ok deraadt

2016-10-07	Beter implementation of chunk canaries: store size in chunk meta data	Otto Moerbeek
	instead of chunk itself; does not change actual allocated size; ok tedu@
2016-10-04	Use the userspace-visible thread register directly in __cerror instead	Philip Guenther
	of indirecting through __errno(). Register naming tweaks and clang testing by patrick@ and jsg@ ok kettenis@
2016-09-30	Make read(2) return EISDIR on directories.	Jeremie Courreges-Anglas
	Years ago Theo made read(2) return 0 on directories, instead of dumping the directory content. Another behavior is allowed as an extension by POSIX, returning an EISDIR error, as used on a few other systems. This behavior is deemed more useful as it helps spotting errors. This implies that it might break some setups. Ports bulk builds by ajacoutot@ and naddy@, ok millert@ bluhm@ naddy@ deraadt@
