From f897461d4fe72bb71854a6d0662de83008caccb7 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 18 Jan 2023 10:32:14 -0500 Subject: fix debugger tracking of shared libraries on mips with PIE main program mips has its own mechanisms for DT_DEBUG because it makes _DYNAMIC read-only, and the original mechanism, DT_MIPS_RLD_MAP, was PIE-incompatible. DT_MIPS_RLD_MAP_REL was added to remedy this, but we never implemented support for it. add it now using the same idioms for mips-specific ldso logic. --- ldso/dynlink.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'ldso/dynlink.c') diff --git a/ldso/dynlink.c b/ldso/dynlink.c index 09f3b0a8..fde5f346 100644 --- a/ldso/dynlink.c +++ b/ldso/dynlink.c @@ -1992,6 +1992,10 @@ void __dls3(size_t *sp, size_t *auxv) size_t *ptr = (size_t *) app.dynv[i+1]; *ptr = (size_t)&debug; } + if (app.dynv[i]==DT_DEBUG_INDIRECT_REL) { + size_t *ptr = (size_t *)((size_t)&app.dynv[i] + app.dynv[i+1]); + *ptr = (size_t)&debug; + } } /* This must be done before final relocations, since it calls -- cgit v1.2.1
