Thanks to Peter Mazinger for pointing this out.

sa_restorer when SA_ONSTACK is set, but it seems to break LTP's
sigaltstack testcase. Some users have reported problems with
sigaltstack as well; hopefully this will fix it.

initialization of the mutex field within DIR struct.
When linked dynamically instead, __pthread_mutex_init will
initialize the mutex itself. Without this fix, any call to
readdir will stuck forever trying to acquire the mutex.

These are mostly the changes necessary to deal with loading the libraries
into memory. A couple new target macros are defined for this purpose, and
the code in dl-elf.c is modified to deal with nommu systems.

|
|
A couple more target macros for ld.so to deal with FD-PIC support. We need
special code to compute the initial got and dpnt, and we need to pass extra
arguments to _dl_get_ready_to_run.
|
|
Add a hash table for function descriptors on FD-PIC targets.
|
|
Change _dl_find_hash to _dl_lookup_hash, as on the NPTL branch.
_dl_find_hash is now a wrapper function around it; unlike on the NPTL branch,
it retains the old interface so that not all callers need to be changed.
_dl_lookup_hash can optionally give its caller a pointer to the module where
the symbol was found.
Introduce ELF_RTYPE_CLASS_DLSYM for lookups from libdl.
Spelling fixes in the Blackfin port, since Alex Oliva's original version of
these patches used _dl_find_hash_mod as the name of the function rather than
_dl_lookup_hash.
|
|
Add the necessary changes in ld.so and libdl to deal with targets that
prepend an underscore to symbol names.
|
|
Add a new function _dl_free. In _dl_malloc, ensure we always get back a full
page from mmap.
Reset _dl_malloc_function and _dl_free_function when libdl is initialized.

system calls actually being inlined, so AVR32 needs to use
__always_inline instead of just inline. The attached patch changes this
for the system calls.

reduction is achieved by direct use of user-supplied PATH_MAX sized
buffer for result (without intermediate copy) and changes
in copy_buf[] usage - now it is used for both "source" pathname
and link name (it works because they have to be less than PATH_MAX combined,
otherwise we return NULL).

Fix minor errors:
- UCLIBC_SHARED_FLAT_ID instead of SHARED_FLAT_ID
- use -Wl,-shared-lib-id properly
Use libc_so.a as the source for the shared libc, in order to be able to
use -mleaf-id-shared-library on the Blackfin.

containing an object built without -fpic/-fPIC - then:
* If __FORCE_SHAREABLE_TEXT_SEGMENTS__, then it gives an error "Can't
modify %s's text section. Use GCC option -fPIC for shared objects,
please.\n" and exits.
* Otherwise, it makes the library's pages writable and relocates it.
If it encounters text relocations in a position-independent executable -
one containing an object built without -fpie/-fPIE/-fpic/-fPIC - then:
* If __FORCE_SHAREABLE_TEXT_SEGMENTS__, it does nothing about making the
pages writable, leading to a crash.
* Otherwise, the loop to make the pages writable uses the same variable
ppnt as used in an outer loop, messing up that outer loop and also causing
a crash.
This patch fixes both cases, by giving an error if
__FORCE_SHAREABLE_TEXT_SEGMENTS__ and saving and restoring ppnt otherwise.
Tested in both cases on ARM EABI.

On cygwin one has to pass
make menuconfig HOST_LOADLIBES="-lcurses -lintl"
otherwise just curses is linked in and some symbols that live in intl are
unresolved. Closes #1554 and possibly a couple of other reports.

The attached patch solve an issue I faced while using the libdbus-glib
waiting for a D-Bus message or the end of a glib timer at the same time.
This specific case of use generate a poll call with a zero timeout. On
platformes with the glibc a zero timeout poll return immetiately even if
there is no file descriptor event. But on platformes with uClibc a zero
timeout poll block until a file descriptor event occurs.

will set the type of common symbols to STT_COMMON
instead of STT_OBJECTS, so the dynamic linker needs
to handle this type os symbols too.
Same changes have been added to glibc (See: bugzilla #5104).
This patch ensures the uclibc will work with later bintuils.

- adjust setting flags accordingly to use (hardcoded, see below) -Wl,
Potential improvements:
*) --warn-unresolved-symbols should perhaps be used for all libs
*) eventually rename LDFLAGS to CC_LDFLAGS
*) probe for compiler driver's notion of flag to use for passing in
linker flags (i.e. don't hardcode "-Wl,")
