2005-05-21Pass main function ptr from crt1 to __uClibc_start_main.Joakim Tjernlund
Kill old crt0/__uClibc_main. This breaks ABI. All apps and toolchain needs to be recompiled. All archs except x86 are now broken and need to be fixed as x86. PPC will be fixed shortly by me, the rest is left to the arch maintainers.
2005-05-10Change strptime so that it only modifies struct tm fields specified.Manuel Novoa III
2005-04-28Added support for clock_getres() and clock_settime() in addition toPeter Kjellerstedt
the already existing clock_gettime(). In addition they will now use the corresponding system calls if they exists, which resulted in a move to libc/sysdeps/linux/common for clock_gettime.c (it was previously located in libc/misc/time).

syscalls. This won't work on 2.2 kernels(I think).
2005-04-16In Bug 116, dicksnippe writes:Mike Frysinger
uClibc's mkstemp/mktemp tries to read /dev/urandom (or /dev/random) to generate random contents for the .XXXXXX part of its argument. In a chrooted environment /dev/[u]random might not be available. Thus the mkstemp call fails. Add back in the braindamaged gettimeofday/getpid code, but only as a fallback for when reading /dev/[u]random fail for whatever reasons.
2005-04-16cbachman writes Bug 195:Mike Frysinger
Add back in the code which sets the default facility if none specified. This may cause issues with klogd when it tries to use the libc's syslog(), but klogd comes with its own syslog() implementation so that's a none issue. For more info, please see the following: http://sources.redhat.com/ml/libc-alpha/2000-03/msg00059.html

Hello, under some circumstances the following small example prints lots of garbage onto the console and into the syslog: #include <syslog.h> int main () { openlog("foo", LOG_CONS|LOG_NDELAY|LOG_PID|LOG_PERROR, LOG_DAEMON); syslog (LOG_WARNING, "mlock: %m"); return 1; } The reason is, that sprintf returns with -1 and vsyslog dumps the complete buffer onto stderr and the syslogd socket. The following patch would fix the problem:

rename UCLIBC_PROPOLICE to UCLIBC_HAS_SSP

adding cruft to include/sys/time.h. But also, there's no sense in making changes like this until we decide how we're going to approach the hidden symbol transition.

Hello! Would the attached patch be acceptable (maybe instead of __libc_gettimeofday using __gettimeofday) We have some issues, see http://bugs.gentoo.org/show_bug.cgi?id=65892

Hi. I found a mismatch between uClibc and kernel in semctl definition. In uClibc/libc/misc/sysvipc/sem.c: static inline _syscall4(int, __semctl, int, semid, int, semnum, int, cmd, union semun *, arg); ... int semctl(int semid, int semnum, int cmd, ...) ... arg = va_arg (ap, union semun); ... return __semctl(semid, semnum, cmd, &arg); But kernel's semctl is: asmlinkage long sys_semctl (int semid, int semnum, int cmd, union semun arg) The last argument is an union semun itself, not a pointer to the union. Here is a patch.

Hi Erik It seems to me that __pthread_once and __pthread_initialize_minimal could be made WEAKs with no stub. The code in rpc_thread.c and __uClibc_main.c appears to expect this. Also, __pthread_return_0 __pthread_return_1 and __pthread_return_void can be static, not to pollute the name space. Jocke

2004-05-08Obligatory forgotten file...Manuel Novoa III
2004-05-08Change clock() to allow wrapping.Manuel Novoa III
Add timegm() function. Make lookup_tzname() static (as it should have been). Have strftime() get timezone information from the passed struct for the %z and %Z conversions when using struct tm extensions.
2004-05-07"Fix" this so that at least things will link when threading is disabled.Manuel Novoa III
Also fix the sizeof() issue since the change to a dynamicly allocated buf. Note! This is still broken wrt threading, but so is the glibc version. I'm just commiting this for new until I can test my rewrite.
2004-04-06Fix a bug noticed by Oleg I. Vdovikin, oleg at cs dot msu dot su.Eric Andersen
This code in uClibc would attempt to set the default facility if none was specified. Except none being specified is 0, which is also LOG_KERN, therefore klogd could never get kernel messages logged as LOG_KERN.
2004-03-18Reduce memory used by static buffers and allocate that memory dynamiclyEric Andersen
instead. Based on an initial patch from Tobias Anderberg, but reworked. I asked Tobias to look into doing something more like what is done in busybox, but that proved to be a pain. One possible concern is that these buffers will probably show up as memory leaks i.e. with valgrind. Perhaps we should add in an atexit call to free this memory right after we allocate it?
2004-03-11Rewrite the err/warn functions as they were broken (__noreturn__ funcsManuel Novoa III
were returning). Anyway, also make them threadsafe and smaller. The error.c file still needs work.
2004-02-11New stdio core. Should be more maintainable. Fixes a couple of bugs.Manuel Novoa III
Codepaths streamlined. Improved performance for nonthreaded apps when linked with a thread-enabled libc. Minor iconv bug and some locale/thread related startup issues fixed. These showed up in getting a gcj-compiled java helloworld app running. Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.

2004-01-14Add a dummy (always fails) wcsftime. This is needed for the libstdc++ localeManuel Novoa III
implementation to build. Later this month I'll add a functional wcsftime.
2004-01-04My mistake. We do need some weak pthread_* funcs. But we were previouslyManuel Novoa III
missing one in the glibc abi, and including a number of extras (which I left in commented). Unfortunately, this brings back the perl pthread bug. Fixing the incorrect weaks in libpthread wasn't sufficient to escape the shared loader bug. :-(

Hello Erik! I have made some cosmetical changes to the files, removed the added SCRT=-fPIC option from building the crt0.S file (but it is a requirement to build them with -fPIC), and changed some comments. I have left the ldso.c patch with PIE_SUPPORT ifdefs, but consider applying it w/o them (see some earlier comment from PaX Team on this issue, as it is considered a bug). To have it work correctly, you'll also need removing COMPLETELY_PIC. One thing is missing: PIE_SUPPORT should be usable only for i386 (for now). Also added the support for propolice protection (that works for me and catches memcpy/strcpy attacks (but needs a special gcc version). Thanks, Peter
2003-12-27Handle the app_fini stuff in exit without requiring atexit().Manuel Novoa III
This avoids pulling in all the malloc/free code for a simple true/false app.
2003-12-27Fix a long-standing bug with pthreads. A couple of linuxthreads filesManuel Novoa III
were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. While fixing this, I also prepended double-underscore to all necessary weak thread funcs in uClibc, and removed all unused weaks. I did a test build, but haven't tested this since these changes are a backport from my working tree. I did test the changes there and no longer need to explicitly add -lpthread in the perl build for perl to pass its thread self tests.
2003-12-14Fix some dst issues in _time_mktime().Manuel Novoa III
Normalize the tm_isdst value to -1, 0, or 1. If no dst for this timezone, then reset tm_isdst to 0.
