Avoid an overflow in the ELF SYSV ABI hash function. The hash function is supposed to return a value less than or equal to 0x0fffffff. Due to a bug in the sample code supplied with the ELF SYSV ABI documentation, the hash function can overflow on 64-bit systems. Apply the same fix used by GNU libc, MUSL libc and FreeBSD.

Treat symlinks better in $ORIGIN determination in ld.so Now symlinking an executable away from the rest of its installation tree no longer prevents it from finding the libraries. This matches the behavior of other OS linkers. Prompted by a behavior change in lang/ghc test suite. Swapped the order of dirname/realpath in _dl_origin_path.

Use a better algorithm for calculating the grpsym library order. The existing code did a full recursive walk for O(horrible). Instead, keep a single list of nodes plus the index of the first node whose children haven't been scanned; lookup until that index catches the end, appending the unscanned children of the node at the index. This also makes the grpsym list order match that calculated by FreeBSD and glibc in dependency trees with inconsistent ordering of dependent libs. To make this easier and more cache friendly, convert grpsym_list to a vector: the size is bounded by the number of objects currently loaded. Other, related fixes: * increment the grpsym generation number _after_ pushing the loading object onto its grpsym list, to avoid double counting it * increment the grpsym generation number when building the grpsym list for an already loaded object that's being dlopen()ed, to avoid incomplete grpsym lists * use a more accurate test of whether an object already has a grpsym list Prompted by a diff from Nathanael Rensen (nathanael (at) list.polymorpheus.com) that pointed to _dl_cache_grpsym_list() as a performance bottleneck.

Simplify _dl_find_symbol(). Currently, it returns three values: - the symbol it found, returned via the second argument - the base offset of the the object it was found in, via the return value - optionally: the object it was found in, returned via the last argument Instead, return a struct with the symbol and object pointers and let the caller get the base offset from the object's obj_base member. On at least aarch64, amd64, mips64, powerpc, and sparc64, a two word struct like this is passed in registers. ok mpi@, kettenis@

On alpha, the buckets of DT_HASH are 8 bytes instead of 4 bytes. This was previously 'implemented' by having the Elf_Word typedef in <sys/exec_elf.h> vary, but that doesn't match the spec and breaks libelf so it's gone away. Implement the variation here by defining our own type locally for this. ok deraadt@

Implement support for DT_GNU_HASH, taking all the interesting bits from Matt Dillon's implementation in DragonFlyBSD commit 7629c631. One difference is that as long as DT_HASH is still present, ld.so will use that to get the total number of symbols rather than walking the GNU hash chains. Note that the GPLv2 binutils we have doesn't support DT_GNU_HASH, so this only helps archs were lld is used. ok kettenis@ mpi@

Finish ld.so's transition to GNU_RELRO: eliminate support for using
__got_{start,end} to find a region to mark read-only. It was only used
for binaries that didn't have a GNU_RELRO segment, but all archs have
been using that for over a year. Since support for insecure-PLT layouts
on powerpc and alpha have been removed, all archs handle GNU_RELRO the
same way and the support can be moved from the MD code to the MI code.

Borrow an idea from DragonFly BSD: factor out the "does this symbol match what we're looking up?" logic from _dl_find_symbol_obj() into matched_symbol(), so that the former is just the "iterate across the hash" logic. matched_symbol() returns zero on "not found", one on "found strong symbol", and negative one on "found weak symbol". The last of those lets the caller give up on this object after finding a weak symbol, as there's no point in continuing to search for a strong symbol in the same object. ok mpi@

Introduce ltrace(1). This tool works with ld.so to inject utrace record for each plt call, allowing to trace a binary linked against shared library at the public function call level. To do so, ltrace(1) sets up some environment variables to enable plt tracing in ld.so, and invokes ktrace(2) for utrace events. ld.so will force lazy binding and will send an utrace record in the plt resolver, without updating the plt. Minimal filtering capabilities are provided, inspired by Solaris' truss -u, to limit tracing to libraries and/or symbol names. Non-traced libraries and symbols will have the regular resolver processing, with the expected plt update. "Get it in" deraadt

Improve support for shared libs linked at non-zero addreses:
- rename private values in struct elf_object to better
describe their meaning:
s/load_offs/obj_base/ "object's address '0' base"
s/load_addr/load_base/ "The base address of the loadable
segments"
- gdb needs the obj_base value so swap positions with load_base in
struct elf_object
- fix a few occurrences of where load_base was used instead of
obj_base.
With help and okay drahn@

Add a new argument sym_size to warn about symbols which have the incorrect size. This replaces 'ifdef notyet' code which was in several of the md files with a single version. sym_size == 0 means do not check, and symbols of type FUNC are not checked.
