2010-09-17ldso: Add implementation of ld.so standalone executionFilippo Arcidiacono
The dynamic linker can be run either indirectly through running some dynamically linked program or library (in which case no command line options to the dynamic linker can be passed and, in the ELF case, the dynamic linker which is stored in the .interp section of the program is executed) or directly by running: /lib/ld-uClibc.so.* [OPTIONS] [PROGRAM [ARGUMENTS]] Stand-alone execution is a prerequisite for adding prelink capabilities to uClibc dynamic linker, as well useful for testing an updated version of the dynamic linker without breaking the whole system. Currently supported option: --library-path PATH use given PATH instead of content of the environment variable LD_LIBRARY_PATH (Mandatory for prelinking) Not supported options: --list list all dependencies and how they are resolved --verify verify that given object really is a dynamically linked object we can handle --inhibit-rpath LIST ignore RUNPATH and RPATH information in object names in LIST This feature can be enabled by setting LDSO_STANDALONE_SUPPORT=y Signed-off-by: Filippo Arcidiacono <filippo.arcidiacono@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2010-08-06config parser: fix memory corruptionTimo Teräs
fgets will happily write over allocated area limits. Adjusted the buffer size according to how much is already read. Also increase the maximum default line length, as 80 is slightly small. It might be better if bb_get_chunk_with_continuation would reallocate the line buffer if it was not user given.

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>

2010-04-22nptl: fix libc internal, dynamically enabled lockingTimo Teräs
Final iteration to fix libc internal locking if libpthread is pulled in by dlopen call (directly or indirectly). We cannot really use the weak symbol trick for shared build, since the symbols won't get refreshed if libpthread is pulled in dynamically. In glibc, they have #ifdef SHARED magic to either use pthread_functions table, or weaks. But as we shared object files with both builds, this does not sounds good either. The reintroduces the libc weaks.c, but uses them now only with static build. For dynamic build, we still use the symbols with same name, but provide weaks in forward.c so they end up dereferencing the pthread_functions table indirectly if we are not linked to libpthread. Mutex initialization is hard coded as inline, as it needs to happen even if libpthread is not initially loaded.

2010-04-16libc: remove libc weak __pthreads_* wrappersTimo Teras
It is not possible to override for libpthread to override the weak libc definitions. This has never worked in uclibc, and does no longer work in glibc either (unless you use LD_DYNAMIC_WEAK). The proper thing to do is have weak prototypes in libc, and definitions in libpthread only. This way libc runs even if those functions are not defined, but just needs to protect against the NULL values (done by implementing __uclibc_maybe_call). This fix the problems if libc is linked before libpthread or if libpthread is pulled by a dependency library.

2009-12-13syslog: fix openlog(xx, LOG_KERN) and optimize a bitDenys Vlasenko
The fix: logfac == 0 in openlog(xx, logfac) is allowed now. Corresponding internal openlog() call in vsyslog() uses explicit LOG_USER in order to set it as a default facility. Optimizations: mylock is not recursive now, since a single intenal call of openlog is converted to a call to openlog_internal which assumes that lock is already taken. No recursive locking is possible now. LogFacility is reduced to byte. cache static LogFile in auto variable fd (smaller code). vsyslog with bogus pri parameter wouldn't lock/unlock and mess with signals - it will just return at once. pass NULL as ident string in internal openlog call - same effect as passing LogTag but smaller code. comment out "if (LogTag)" checks - it is never NULL. use the same struct sigaction for setting new sigaction and for saving old one - saves ~32 bytes of stack.
