8 years agoAdd protected symbols support for all architectures
Salvatore Cro [Wed, 12 Jan 2011 09:27:16 +0000 (10:27 +0100)]
Add protected symbols support for all architectures

Protected symbols are global symbols for which interposition is not allowed.
We manage them in generic _dl_lookup_hash function. To handle protected symbols
we need to get a reference to the module that defines the symbol itself.
So we pass a new parameter 'struct symbol_ref' to the __dl_lookup_hash
that is defined as below:

struct symbol_ref {
  const ElfW(Sym) *sym;
  struct elf_resolve *tpnt;
};

The tpnt field is used as an ouput parameter and refers to the module which defines
the protected symbol.
Further it can be used as output parameter for TLS relocations and FDPIC case.
The sym field is instead used as an input parameter to detect the visibility of the
symbol we are looking-up.
In this way we get rid of different signatures for _dl_lookup_hash, allowing to remove
the _dl_find_hash wrapper.
This new structure is also suitable for prelink integration.

that arch specific version of libc-tls.c (MIPS and ALPHA) includes it.
The arch libc-tls.s is aimed to provide the implementation of __tls_get_addr

If I'm building with "-fPIC -pg" it instruments all C functions with

-fno-omit-frame-pointer is sometimes useful for profiling too

Also the upcoming -fsplit-stack will be broken by this too (that might
need additional uclibc support though).

And I'm pretty sure there's also other similar compiler features.
There's no predefined #defines in gcc for any of these.

What I'm trying to say that there are *numerous* situations when the
compiler can create stack frame for you without you ever knowing it. And
if you want to do a tail jump, you really should be doing it from .S

Fix msync() redefinition for noMMU build

An architecture that _may_ have a MMU (and thus implements
the msync syscall), but for which the kernel and uClibc are built as
noMMU, we have a stub for msync.

Thanks to Steven J. Magnani for noticing.

8 years agomips: fix errno setting after syscall

mips: fix errno setting after syscall

If there was an error during syscall then after it's completion a3
register holds a non-zero value and v0 holds an actual error code which
should be saved in errno. This can be achieved by calling
__syscall_error with the value from v0 as a parameter. So this value
should be stored in a0, but the appropriate assembly instructions are
missing. Fixed this now by adding "move a0, v0".

I think it was once fixed by 58c5f8ba4cdf62342d05a546d15404cbbb3c4e07
but then something went wrong. Again...
