| * avoid warning about unused variableBernhard Reutner-Fischer2009-11-251-11/+10
| | | | | | | | | | | | If LDSO_SEARCH_INTERP_PATH is off then ptmp wasn't used. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
| * nommu: use MAP_UNINITIALIZE for mallocsMike Frysinger2009-11-232-2/+2
| | | | | | | | | | | | | | | | | | Now that the kernel supports MAP_UNINITIALIZE, have the malloc places use it to get real uninitialized memory on no-mmu systems. This avoids a lot of normally useless overhead involved in zeroing out all of the memory (sometimes multiple times). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | The TLS merge 534661b91c9849 introduced multiple style problems as well as random breakage: - missing _dl_free - incomplete parametrization of _dl_lookup_hash - restore FDPIC handling in _dl_lookup_hash Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: rename __dl_boot to __startMike Frysinger2009-07-232-11/+8
| | | | | | | | | | | | | The entry symbol is __start rather than __dl_boot. While in the past this was silently ignored, now with common code checking the _start symbol in C code, we end up with link errors: ldso/ldso/ld-uClibc_so.a(ldso.oS): In function `__dl_get_ready_to_run': ldso/ldso/ldso.c:(.text+0x2b30): undefined reference to `__start' collect2: ld returned 1 exit status make[1]: *** [lib/ld-uClibc.so] Error 1 Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | | The order of attributes in a function definition matters and in a few places in the Blackfin code, it was being applied to the return type instead of the function itself.

* Blackfin: add elf_machine_load_address() stubMike Frysinger2009-07-231-0/+8
| | | | | | | | | | | The Blackfin port never defined elf_machine_load_address() because the one place this code is called never matters to us. But without it, common code likes to hit a build failure, so stub it out. ldso/ldso/dl-startup.c: In function '_dl_start': ldso/ldso/dl-startup.c:170: warning: implicit declaration of function 'elf_machine_load_address' Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | M5485 processor 1. Disable mmap2() if we're compiling for coldfire and fall back to mmap(). It seems to map a different file area on a 2.6.25 linux kernel. 2. Uses pc-relative addresing[1], computes ADDR_ALIGN, PAGE_ALIGN and OFFSET_ALIGN relatively to _dl_pagesize[3]. On coldfire/M5485 _dl_pagesize is 0x2000.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
