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:
|
|
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.

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.

rm.patch:
* Define $(RM) as rm -f in Rules.mak and test/Rules.mak
(this is the same definition as gmake uses by default).
* Change all occurrences of rm and rm -f into $(RM).

It turns out that uClibc's syslog.c does not close sockets when
doing retries and when it exits due to errors. This patch fixes
it.

using SOCK_STREAM if SOCK_DGRAM fails.

we were opening the socket() as SOCK_STREAM instead of
using SOCK_DGRAM like we should have done.

support for __FORCE_NOGLIBC per Brian Stafford

tree is less messy now (which helps), all libraries are placed into
uClibc/lib when compiling, all libraries now use a consistant mechanism
for being built, all libraries use a consistant naming scheme where the
lib name includes the uClibc version number, which makes ldconfig
happy and willing to work with us.

This required we use _LIBC instead of __LIBC__ to be consistent with glibc.
This had some sideffects in sys/syscalls.h. While fixing things, I made
everything use __set_errno() for (eventual) thread support.
