2008-12-03- Use runtime pagesize (Jeremy Kerr)Bernhard Reutner-Fischer
Some powerpc machines can support 64k pages, enabled by the CONFIG_64K_PAGES option in linux. However, the uClibc dynamic loader won't currently work on these machines, as it uses hard-coded values (PAGE_ALIGN, ADDR_ALIGN and OFFS_ALIGN) in the ldso architecture-specific headers. When running on a kernel with 64k pages, ld.so tries to mmap with 4k-aligned addresses, rather than 64k, so mmap fails with -EINVAL. When booting a 64k machine with a uClibc dynamic linker, init fails with: /init:500: can't map '/lib/libc.so.0' /init:500: can't map '/lib/libc.so.0' /init:500: can't map '/lib/libc.so.0' /init: can't load library 'libc.so.0' Kernel panic - not syncing: Attempted to kill init! This change allows ld.so determine these alignment masks at runtime, rather than compile-time. Since we have the _dl_pagesize variable available, we can use that to generate the appropriate masks. Since almost all of the architectures can use the common definitions for the _ALIGN macros, we can consolidate them all in ldso.h, and override in the sysdep headers where necessary (ie, mips). This allows me to start a uClibc-based root fs on a 64k machine. Signed-off-by: Jeremy Kerr <jk at ozlabs org>
2008-11-18Move _dl_iterate_phdr into libc.so.0 and libc.a (as glibc does).Carmelo Amoroso

2008-11-03Prefix variables defined in INIT_GOT define for AVR32 archHans-Christian Egtvedt
This patch will prefix the i and nr_got variable with an underscore to seperate them from any variables already present in the functions where the macro is used. Needed to silence compiler warnings. Signed-off-by: Hans-Christian Egtvedt <hans-christian.egtvedt@atmel.com>

Closes #3824
2008-10-29- fix use after free (Kevin Day)Bernhard Reutner-Fischer
dl_cleanup will call do_dlclose with the handle. Inside of do_dlclose, the handle will ultimately get free'd.
2008-10-24- tidy up inline:Bernhard Reutner-Fischer
ldso and syscalls are __always_inline (the latter would need more cleanup)

2008-09-25- ARMV5 can use STRD and LDRD access instructions but these accesses need to beBernhard Reutner-Fischer
8 byte aligned. The dynamic linker's malloc needs to match this so structures become 8 byte aligned to void unaligned accesses. (71_all_uClibc-arm_fix_alignment.patch from gentoo)

2008-09-13xtensa: Stack unwinding on Xtensa requires that the return address register ↵Chris Zankel
always be valid. This patch fixes a part of ldso that had been using an Xtensa CALL0 instruction to get the current PC value, which temporarily clobbered the return address register. The revised code just loads the address of a label in the code. See my change to GCC from 2007-12-20 for more info (http://gcc.gnu.org/ml/gcc-patches/2007-12/msg01023.html).

2008-08-08Fix SH ldso sequence startup.Carmelo Amoroso
Pass via r4 the rtld finalizer _dl_fini to the user application. This will be the 6^ arg of __uClibc_main and will be registered with 'atexit'. In this way the dynamic linker will be able to call destructors defined within the loaded DSOs.
