2011-03-07ldso: use ADDR_ALIGN instead of hard-coded valueCarmelo Amoroso
Use ADDR_ALIGN to align the minvma when loading shared libraries instead of the hard coded 0xffffU value. This fixes teh stand/alone support on ARM as reported in bug #3133.

2011-01-20ldso: get rid of _dl_lookup_hashCarmelo Amoroso
Now _dl_find_hash and _dl_lookup_hash are exactly the same, we can get rid of the _dl_lookup_hash, reverting the _dl_find_hash from a wrapper of _dl_lookup_hash to its original role. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2011-01-20Add protected symbols support for all architecturesSalvatore Cro
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.

2011-01-11syslog: fix 'everyone logs with user facility'Roman I Khimov
It's been found that on uclibc-based system most of the programs log with 'user' facility despite the calls to openlog() with other facilities explicitly set. Most but not all. Investigating that I've found that the ones logging with proper facilities used LOG_NDELAY in openlog(). The problem is that LogFacility is overwritten in openlog_intern and LOG_USER is passed to it from vsyslog() no matter what the program set with openlog().

2011-01-06buildsys: headers target should not depend on sysnum.hCarmelo Amoroso
The generation of the sysnum.h has to be a prerequisite of 'pregen' target instead of headers, because it needs the compiler already available. The so called C bootstrap headers are required to build the compiler by invoking 'make headers', so the 'headers' target cannot relies itself on the compiler to be invoked.

2011-01-06buildsys: fix make release targetCarmelo Amoroso
According to git man page the syntax for git archive should have the <tree-ish> as last argument. Indeed using git 1.5.5.6 the tarball was not properly created. Newer version (i.e. 1.6.3.3) works fine even if HEAD comes before other option. For backward compatibility use a syntax that is fine with older git.

The respective source has to depend on a given set of headers. Depending all on headers is papering over an eventual missing other dependency, so reverting. This reverts commit 4d81f2a74578f819285b131c682e8d2f6c315c4e.
