2011-03-05Add support for DSBT ELF to ld.soMark Salter
This adds support for DSBT ELF to ld.so. This uses loadmaps like FD-PIC. Some code is added in ld.so to initialize the DSBT tables, and there's also a new target macro FINISH_BOOTSTRAP_RELOC.

2011-03-05Add Makefile support for DSBT ELF.Bernd Schmidt bernds_cb1@t-online.de
This adds support for a new binary format, DSBT ELF, to the Makefiles. Every shared library is assigned a DSBT index, and the link.so macro is adjusted to ensure the correct linker argument is passed. Configuration and ldso support will follow in separate commits.

2011-02-25nptl:arm: add a wrapper for .cfi_sections pseudo-opsCarmelo Amoroso
ARM disables by default the support for ASM CFI directives. Anyway using an old version of binutils that does not support some new pseudo-op, the build fails as below: AS libpthread/nptl/sysdeps/unix/sysv/linux/close.oS libpthread/nptl/sysdeps/unix/sysv/linux/close.S: Assembler messages: libpthread/nptl/sysdeps/unix/sysv/linux/close.S:9: Error: unknown pseudo-op: `.cfi_sections' The problem is that the .cfi_sections pseudo should be wrapped by a macro that expands to nothing when the CFI is off.

2011-02-22bfin: fix fp reference in _JMPBUF_UNWINDSMike Frysinger
We want to access the frame pointer, so do so directly rather than "overflowing" the pregs array and ending up at the fp member. This fixes the Blackfin build warnings: libpthread/linuxthreads.old/ptlongjmp.c: In function 'pthread_cleanup_upto': libpthread/linuxthreads.old/ptlongjmp.c:35: warning: array subscript is above array bounds libpthread/linuxthreads.old/ptlongjmp.c:56: warning: array subscript is above array bounds Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-02-21bfin: add support for new cacheflush syscallSteve Kilbane
Newer gcc's will generate a call to cacheflush when updating jump tables, and that has to be done in kernel space (to avoid hardware anomalies). So make sure uClibc provides that symbol. Signed-off-by: Steve Kilbane <steve@whitecrow.demon.co.uk> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-02-09*printf: Violation of precision with null stringJones Desougi
When a string format is processed and the argument is NULL, this yields "(null)" regardless of precision. This does not make sense, precision should not be exceeded. A simple test shows that glibc outputs nothing if precision is smaller than six and the attached patch implements this same behaviour. Consider the not uncommon case of strings implemented like this: struct string { int len; char *ptr; }; There is often no nultermination and they may be printed like this: printf("%.*s", string.len, string.ptr); If len is 0 then ptr may be anything, but NULL is a common value. Obviously the empty string would be expected, not "(null)". Signed-off-by: Jones Desougi <jones.desougi@27m.se> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2011-01-11syslog: fix 'everyone logs with user facility'Roman I Khimov
It's been found that on uclibc-based system most of the programs log with 'user' facility despite the calls to openlog() with other facilities explicitly set. Most but not all. Investigating that I've found that the ones logging with proper facilities used LOG_NDELAY in openlog(). The problem is that LogFacility is overwritten in openlog_intern and LOG_USER is passed to it from vsyslog() no matter what the program set with openlog().
