2013-02-05libc: atexit: reuse free slots at the end of exit functions tableRonald Wahl
Continuosly dlopen and dlclose of shared object will cause a memory leak in atexit function. This fix reuse free slots at the end of the list.

2013-01-26buildsys: gen_bits_syscall_h: do not leave undefined SYS_xxx aroundMike Frysinger
If we end up doing '#undef __NR_xxx', we don't want to leave the corresponding SYS_xxx symbol defined. So undef it too. For example, with the ARM EABI layer, we have a bunch of legacy syscalls that we define early on and then later undefine (such as __NR_utime). But we left SYS_utime defined so code that tests for that define before using it would be broken (since it'd be defined to a non-existent symbol).

2013-01-09dl: fix dlsym lookups with RTLD_NEXTTimo Teräs
The current code for dlsym() when invoked with RTLD_NEXT lookup searches for the module where it's being called from, and executes the _dl_find_hash only for the next module in the chain. However, if the looked symbol is not there, the rest of the modules are not checked. Generally this is not a problem as symbols are merged for the parent modules; so this affects only RTLD_NEXT. This patch adds a loop iterating through all the following modules.

If the syscall returns with an error the stack pointer and r4 register are not restored because the instruction 'ldmnefd sp!, {r4}' is executed after branching to '__error' label.

Setjmp was only saving the lower order of registers (a0-a3) correctly, but not the higher ones (a4-a8/a12). The change also includes additional information, and renames many of the registers, so that setjmp and longjmp look more like the inverse of each other. Signed-off-by: Chris Zankel <chris@zankel.net>

Update libc/sysdeps/linux/common/sys/ptrace.h to latest from glibc's sysdeps/unix/sysv/linux/sys/ptrace.h. This adds definitions for operations: - PTRACE_GETREGSET - PTRACE_SETREGSET - PTRACE_SEIZE - PTRACE_INTERRUPT - PTRACE_LISTEN And adds flags: - PTRACE_SEIZE_DEVEL And adds event codes: - PTRACE_EVENT_SECCOMP This is to allow access to the generic interface for accessing architecture specific regsets using the corresponding NT_* types, required for new Linux kernel architecture ports.
