2017-04-11fix dl_iterate_phdr in static PIE binariesRich Felker1-0/+5
analogous to commit 5bf7eba213cacc4c1220627c91c28deff2ffecda, use of AT_PHDR/PT_PHDR does not actually work to find the program base, and the method with _DYNAMIC vs PT_DYNAMIC must be used as an alternative. patch by Shiz, along with testing to confirm that this fixes unwinding in static PIE.
2017-03-14in static dl_iterate_phdr, fix use of possibly-uninitialized aux dataRich Felker1-1/+1
this could only happen if an incomplete auxv was passed into the program, but it's better to just initialize the data anyway.
2016-01-25adapt static dl_iterate_phdr not to depend on !defined(SHARED)Rich Felker1-4/+3
like elsewhere, use a weak alias that the dynamic linker will override with a more complete version capable of handling shared libraries.
2012-10-31add dl_iterate_phdr interfaceRich Felker1-0/+43
patches by Alex Caudill (npx). the dynamic-linked version is almost identical to the final submitted patch; I just added a couple missing lines for saving the phdr address when the dynamic linker is invoked directly to run a program, and removed a couple to avoid introducing another unnecessary type. the static-linked version is based on npx's draft. it could use some improvements which are contingent on the startup code saving some additional information for later use.
