2024-02-22Introduce time64 support.Dmitry Chestnykh
This patch introduces *time64 syscalls support for uClibc-ng. Currently the redirection of syscalls to their *time64 analogs is fully supported for 32bit ARM (ARMv5, ARMv6, ARMv7). The main changes that take effect when time64 feature is enabled are: - sizeof(time_t) is 8. - There is a possibility os setting date beyond year 2038. - some syscalls are redirected: clock_adjtime -> clock_adjtime64 clock_getres -> clock_getres_time64 clock_gettime -> clock_gettime64 clock_nanosleep -> clock_nanosleep_time64 clock_settime -> clock_settime64 futex -> futex_time64 mq_timedreceive -> mq_timedreceive_time64 mq_timedsend -> mq_timedsend_time64 ppoll -> ppoll_time64 pselect6 -> pselect6_time64 recvmmsg -> recvmmsg_time64 rt_sigtimedwait -> rt_sigtimedwait_time64 sched_rr_get_interval -> sched_rr_get_interval_time64 semtimedop -> semtimedop_time64 timer_gettime -> timer_gettime64 timer_settime -> timer_settime64 timerfd_gettime -> timerfd_gettime64 timerfd_settime -> timerfd_settime64 utimensat -> utimensat_time64. - settimeofday uses clock_settime (like in glibc/musl). - gettimeofday uses clock_gettime (like in glibc/musl). - nanosleep uses clock_nanosleep (like in glibc/musl). - There are some fixes in data structures used by libc and kernel for correct data handling both with and without enabled time64 support.

While they are not a problem per-se they cause issues with some tooling (such as clang coverage) and are confusing to the reader.

2011-10-12libc: fix daylight saving time handlingGuillaume Bourcier
The algorithm computing daylight saving time incorrectly adds a day for each month after January for leap years. The clock shift from/to DST can be delayed if the last Sunday of a transition month is exactly seven days before the first of the following month. This change adds a day for the February month only.

2010-07-27Fix ctime() standard compliance bugDavid A Ramos
fixes issue2209: ctime() was updated in 0.9.31 to call localtime_r() instead of localtime() to avoid using a static buffer. Unfortunately, this change replaces the static buffer (which is zeroed out on initialization) with an uninitialized local buffer. In the common case, this has no effect. However, with a sufficiently large time_t value, the value returned differs from that returned by asctime(localtime(t)), and thus violates the ANSI/ISO standard. An example input is (on a 64-bit machine): time_t t = 0x7ffffffffff6c600; Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2008-06-04This fixes a problem with the move of libc_hidden_proto to string.h.Bernd Schmidt
The obsolete functions bcopy, index, etc. are not supposed to be used within uClibc itself. Hence, there is no libc_hidden_def for them, but the previous patch did not just move libc_hidden_protos, it also added new ones for the legacy functions. As a result, programs which use these functions can no longer link with uClibc. This fixes it by removing the unnecessary libc_hidden_protos. I've also removed all inclusions of <strings.h> from uClibc source files: since we define _GNU_SOURCE, it is sufficient to include <string.h>. We then do not need to duplicate the libc_hidden_proto block in <strings.h>.

2008-05-19Moving libc_hidden_proto's into #ifdef UCLIBC_INTERNAL blockDenis Vlasenko
in string.h and strings.h. This caught unguarded string ops in libc/inet/ethers.c __ether_line_w() function. I will wait for fallout reports for a week or so, then continue converting more libc_hidden_proto's.
2008-04-12Functions should be either exported in public .h filesDenis Vlasenko
and marked with libc_hidden_proto/def(), or not be exported in .h files and be hidden (or even static if possible). We have five functions which violate this. Fixing: netdb.h: export ruserpass() rpc/rpc.h: export xdr_accepted_reply() and xdr_rejected_reply() make inet_ntoa_r static function (it is not exported in any .h file) make _time_tzset hidden function (it is not exported in any .h file)
2006-12-07Major cleanup of internal mutex locking. Be more consistant in how we doEric Andersen
things, and avoid potential deadlocks caused when a thread holding a uClibc internal lock get canceled and terminates without releasing the lock. This change also provides a single place, bits/uClibc_mutex.h, for thread libraries to modify to change all instances of internal locking.

2006-11-02In bug 622, JohnAta writes:Eric Andersen
In 2005, Congress passed a law so that in 2007, the second week of March starts DST. Previously, it was the first week of April. The uclibc time library routines apparently have not been updated to reflect this new processing. Using the current version of uclibc, on March 11, 2007 the reported time will be incorrect.
