* mips/ldso: Check for TLS relocation in elf_machine_type_class.Khem Raj2010-01-252-16/+35
| | | | | | | * Store the symbol adress received from _dl_find_hash and do not recompute it. Signed-off-by: Khem Raj <raj.khem@gmail.com>
* ldso: tweak shadow warning with preload file supportBernhard Reutner-Fischer2010-01-211-5/+4
| | | | | | The stat buffer is already declared at the top of the function. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
* mips/nptl: Pass correct parameters to dl_find_hash when resolving TLS ↵Khem Raj2010-01-141-6/+14
| | | | | | | | | relocations. Make use of macros from sys/asm.h in crt1.S These two changes are needed for mips nptl to boot once again. Signed-off-by: Khem Raj <raj.khem@gmail.com>

* check if USE_TLS is defined before useHans-Christian Egtvedt2009-12-176-28/+28
| | | | | | | | | | | This patch will convert all the #ifdef USE_TLS and #if USE_TLS to #if defined(USE_TLS) && USE_TLS. By checking if the USE_TLS is defined before checking its value will result in correct behavior for architectures not defining this config symbol.

* 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>
* ldso: let people disable the implicit path searchMike Frysinger2009-11-221-0/+2

* ldso: drop duplicated/unused definesMike Frysinger2009-10-151-23/+0
| | | | | | | We already include bits/fcntl.h for some of these defines, and most of the bits/stat.h defines are unused. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* ldso: unify and cleanup _dl_mmap codeMike Frysinger2009-10-151-40/+22

* ldso: define MAP_FAILED for everyoneMike Frysinger2009-10-151-1/+1
| | | | | | This fixes build errors where common code has started using MAP_FAILED. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* ldso: clean up breakage in tls mergeMike Frysinger2009-10-1514-159/+137
| | | | | | | | | | 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>
* ldso: fixup all the rest of the calls to _dl_find_hashAustin Foxley2009-10-147-13/+13
| | | | | | | | With TLS _dl_find_hash grew an extra param. These archs don't have TLS reloc support yet, but they do need to compile without it. Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

* ldso: use MAP_FAILED with ld.so.cacheMike Frysinger2009-10-071-5/+5
| | | | | | | Rather than use our own custom casted -1 value, just use the MAP_FAILED that common code already sets up for us for mmap(). 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>
* Blackfin: fix incorrect attribute orderMike Frysinger2009-07-231-1/+2
| | | | | | | | | | | | | | | | | 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. In file included from ldso/ldso/ldso.c:43: ldso/ldso/bfin/elfinterp.c: At top level: ldso/ldso/bfin/elfinterp.c:42: warning: '__visibility__' attribute ignored on non-class types In file included from ldso/ldso/bfin/elfinterp.c:341, from ldso/ldso/ldso.c:43: libc/sysdeps/linux/bfin/crtreloc.c: At top level: libc/sysdeps/linux/bfin/crtreloc.c:91: warning: 'visibility' attribute ignored on non-class types Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* 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>
* ldso: fix building for FDPIC systemsMike Frysinger2009-07-231-1/+1
| | | | | | | | | | The force shareable code missed a spot of using the DL_RELOC_ADDR() indirection thus leading to invalid operands: ldso/ldso/ldso.c: In function '_dl_get_ready_to_run': ldso/ldso/ldso.c:409: error: invalid operands to binary + (have 'Elf32_Addr' and 'struct elf32_fdpic_loadaddr') 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.
