2011-12-22libdl: rudimentary locking for dlopen/dlsym/dlcloseTimo Teräs
This implements big-dlfcn lock to allow multithreaded usage of dlopen/dlsym/dlclose. We should really clean up the dl code so we can use more fine grained locking or even RCU where appropriate. But at least we won't crash now. Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2011-12-22sys/queue.h: update to eglibc versionNatanael Copa
Xen needs SIMPLEQ_* queue types which was not provided from the old uclibc queue.h. Use same implementation as eglibc.

2011-12-03x86_64: add PLT bypass for __sigsetjmpMike Frysinger
The current x86_64 setjmp helpers incur a reloc, so fix that up. $ readelf -r lib/libc.so.0 ... Relocation section '.rela.plt' at offset 0xb058 contains 10 entries: Offset Info Type Sym. Value Sym.

2011-12-03getutid: add a hidden defMike Frysinger
The pututline func calls getutid, so add a hidden def for it to avoid plt relocs: $ readelf -r lib/libc.so.0 ... Relocation section '.rela.plt' at offset 0xb058 contains 11 entries: Offset Info Type Sym. Value Sym. Name + Addend 000000236000 01cf00000007 R_X86_64_JUMP_SLO 00000000000190ab getutid + 0 ...

2011-11-27ldso: bfin: fix sram_flags initMike Frysinger
An earlier version had this, but was lost as code was shuffled around. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-11-27ldso: bfin: shrink sram mapping funcMike Frysinger
The L1 data and L2 code paths duplicate a lot, so unify them. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-11-27ldso: fdpic: clean up styleMike Frysinger
There should (hopefully) be no functional changes here. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-11-27ldso: fdpic: unify duplicate bfin/frv logicMike Frysinger
Much of the logic in the bfin/frv subdirs is FDPIC specific and not arch specific. So start a new fdpic/ subdir to keep common things. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-11-27make ARRAY_SIZE commonly available internallyMike Frysinger
Some places have opencoded the ARRAY_SIZE macro, so move it to a global internal location so other places can leverage it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-11-27ldso: use __func__ rather than __FUNCTION__Mike Frysinger
The former is part of a standard (C99) while the latter is not. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-11-26buildsys: drop manual TARGET_SUBARCH .config lookupMike Frysinger
We source the .config file, so there should be no need to manually extract it. If the sourcing doesn't work, then a lot of things break in this file. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-11-23libc: do not rely upon ulimit kernel syscall.Carmelo Amoroso
On several architectures __NR_ulimit syscall number is currently defined but it is remapped onto sys_ni_syscall, while on other architectures they are not longer defined. So use {get,set}rlimit only to implement ulimit interface. It fixes LTP ulimit01 test case.

2011-11-23libdl: fix size parameter when unmap library in dlcloseFilippo Arcidiacono
Fix size parameter when unmap a library by means of dlclose, by taking into account the p_vaddr of first PT_LOAD segment, so it works also for prelinked shared objects. Unmapping of dlopen shared libraries is broken since 94cc6edb78a12655c0602a246fa1cbdc8c6d0ad9 Signed-off-by: Filippo Arcidiacono <filippo.arcidiacono@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
