to _dl_setup_stack_chk_guard, as in glibc. SSP requires now binutils-2.16.1 and newer. Add NOT_IN_libc/IS_IN_libc. Began using -DSHARED in uClibc_main.c, there are more candidates in there. Move back dl_protect_relro to it's earlier place.

archs lack proper crt1. The Makefiles in extra/scripts are intended to be linked into each dir, where it is necessary to build locally.

objects at once; use :=//$</$^; use CRT_SRC/CRT_OBJ/SCRT_OBJ/CSRC/COBJ/SSRC/SOBJ/MSRC/MOBJ where no more is needed, if only CSRC is present use OBJS directly instead of COBJ; CTOR_TARGETS are created directly in lib; remove unused/unneeded parts. Hope I haven't broken too much.

some auxillary TLS set up has to happen beforehand. This has been tested for almost two months now and I am tired of chasing it around in my merges. Look in the NPTL trunk if you want more information.

Moved guard_setup to __uClibc_main.c, the only place where it is called.
Removed SIGKILL option, not usable with sigaction.

If _DL_FINI_CRT_COMPAT is defined, _dl_fini is setup to run at exit via
atexit(), but this makes it run _before_ the fini (__app_fini()) of the
app, causing stuff like sandbox that frees structs, etc via its fini to
segfault.

libc/misc/time/time.c does not compile if __UCLIBC_HAS_TZ_FILE__ is disabled
but __UCLIBC_HAS_TZ_CACHING__ is enabled. The following patch fixes this
issue.

consistency.

1) Need to negate tm_gmtoff field value when used. (bug 336).
2) Deal with NULL ptr case for tm_zone field, which was causing
segfaults in both the NIST/PCTS tests and the Python 2.4.1
self-test suite.
NOTE: We set uninitialized timezone names to "???", and this
differs (intentionally) from glibc's behavior.

be able to run apps built with 0.9.27. This also renames
__uClibc_start_main to __uClibc_main.
This compat option should be removed some time after 0.9.28 is released.
Let me know if you don't like this change.

position of envp in C code based on argv and argp. No need to
caclulate that in asm for N arches. This way, we better match
what glibc does. All arches will need to be fixed to match up
with this change.

__libc_csu_init and
_fini vs. __libc_csu_fini remains to do.

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.

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).

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.
|
|
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:

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.
|
|
binaries where the standard file descriptors are not opened.

Hello!
Would the attached patch be acceptable (maybe instead of
__libc_gettimeofday using __gettimeofday)
We have some issues, see

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.
