2020-06-02	reformat clock_adjtime with always-true condition removed	Rich Felker	1	-48/+46

2020-06-02	always use time64 syscall first for clock_adjtime	Rich Felker	1	-2/+1
	clock_adjtime always returns the current clock setting in struct timex, so it's always possible that the time64 version is needed.
2020-06-02	fix broken time64 clock_adjtime	Rich Felker	1	-1/+1
	the 64-bit time code path used the wrong (time32) syscall. fortunately this code path is not yet taken unless attempting to set a post-Y2038 time.
2019-10-20	clock_adjtime: generalize time64 not to assume old struct layout match	Rich Felker	1	-11/+46
	commit 2b4fd6f75b4fa66d28cddcf165ad48e8fda486d1 added time64 for this function, but did so with a hidden assumption that the new time64 version of struct timex will be layout-compatible with the old one. however, there is little benefit to doing it that way, and the cost is permanent special-casing of 32-bit archs with 64-bit time_t in the public interface definitions. instead, do a full translation of the structure going in and out. this commit is actually a revision to an earlier uncommited version of the code.
2019-08-02	clock_adjtime: add time64 support, decouple 32-bit time_t, fix x32	Rich Felker	1	-0/+110
	the 64-bit/time64 version of the syscall is not API-compatible with the userspace timex structure definition; fields specified as long have type long long. so when using the time64 syscall, we have to convert the entire structure. this was always the case for x32 as well, but went unnoticed, meaning that clock_adjtime just passed junk to the kernel on x32. it should be fixed now. for the fallback case, we avoid encoding any assumptions about the new location of the time member or naming of the legacy slots by accessing them through a union of the kernel type and the new userspace type. the only assumption is that the non-time members live at the same offsets as in the (non-time64, long-based) kernel timex struct. this property saves us from having to convert the whole thing, and avoids a lot of additional work in compat shims. the new code is statically unreachable for now except on x32, where it fixes major brokenness. it is permanently unreachable on 64-bit.
2019-07-20	refactor adjtimex in terms of clock_adjtime	Rich Felker	1	-0/+2
	this sets the stage for having the conversion logic for 64-bit time_t all in one file, and as a bonus makes clock_adjtime for CLOCK_REALTIME work even on kernels too old to have the clock_adjtime syscall.
2013-12-12	include cleanups: remove unused headers and add feature test macros	Szabolcs Nagy	1	-2/+0

2012-09-16	add clock_adjtime, remap_file_pages, and syncfs syscall wrappers	Rich Felker	1	-0/+9
	patch by Justin Cormack, with slight modification
