* MFC r312288: rtld: do not rely on a populated GOT on amd64Ed Maste2017-01-262-2/+14
| | | | | | | | | | | | | | | | | | | | | On rela architectures GNU BFD ld and gold store the relocation addend in GOT entries (in addition to the relocation's r_addend field). rtld previously relied on this to access its own _DYNAMIC symbol in order to apply its own relocations. However, recording addends in the GOT is not specified by the ABI, and some versions of LLVM's LLD linker leave the GOT uninitialized on rela architectures. BFD ld does not populate the GOT on sparc64, and sparc64 rtld has a machine-dependent rtld_dynamic_addr() function that returns the _DYNAMIC address. Use the same approach on amd64, obtaining the %rip- relative _DYNAMIC address following a suggestion from Rafael Espíndola. Architectures other than amd64 should be addressed in future work.

* MFC r309411: Retire long-broken/unused static rtld supportEd Maste2017-01-034-19/+11
| | | | | | | | | | | | | | | | | | | | | | rtld-elf has some vestigial support for building as a static executable. r45501 introduced a partial implementation with a prescient note that it "might never be enabled." r153515 introduced ELF symbol versioning support, and removed part of the unused build infrastructure for static rtld. GNU ld populates rela relocation addends and GOT entries with the same values, and rtld's run-time dynamic executable check relied on this. Alternate toolchains may not populate the GOT entries, which caused RTLD_IS_DYNAMIC to return false. Simplify rtld by just removing the unused check. If we want to restore static rtld support later on we ought to introduce a build-time #ifdef flag. PR: 214972 Notes: svn path=/stable/11/; revision=311156

* MFC 308456: Pass the correct flag to find_symdef() from _rtld_bind().John Baldwin2016-12-012-3/+3
| | | | | | | | | | | When symbol versioning was added to rtld, the boolean 'in_plt' argument to find_symdef() was converted to a bitmask of flags. The first flag added was 'SYMLOOK_IN_PLT' which replaced the 'in_plt' bool. This happened to still work by accident as SYMLOOK_IN_PLT had the value of 1 which is the same as 'true', so there should be no functional change. Notes: svn path=/stable/11/; revision=309371

* Update blacklist support in ftpd to clarify fd usageKurt Lidl2016-06-062-13/+11
| | | | | | | | | | | | | | | | The ftp daemon dups the control socket to stdin and uses that fd throughout the code. Clarify this usage slightly by changing from explicit use of "0" for the fd to a variable, to make it clear what the zero represents in the non-blacklist code. Make the blacklist_notify routine use STDIN_FILENO so as to have less of a "magic number" feel to the code.
