From cb7364414157c42de5ea618d98e2be9eff1894ba Mon Sep 17 00:00:00 2001 From: George Barrett Date: Sun, 15 Dec 2019 11:12:09 +1100 Subject: Fix disabling of solib probes when LD_AUDITing The SVR4 solib event handler determines whether an event is related to a non-base link namespace by comparing the event's debug struct address to the debug struct address of the initial program image. However, this can fail when using LD_AUDIT as audit libraries are loaded before the loader has initialised the initial program image's debug struct. When the event handler fails to find the debug struct, the probe-based debugger interface is disabled and a warning is flagged to the user. This commit adds a fallback test to help determine whether an event is for a foreign link namespace when the debug struct isn't available. gdb/ChangeLog: 2019-12-15 George Barrett * solib-svr4.c (svr4_handle_solib_event): Add fallback link namespace test for when the debug struct isn't available. --- gdb/ChangeLog | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'gdb/ChangeLog') diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 0ba175a..acf9106 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2019-12-21 George Barrett + + * solib-svr4.c (svr4_handle_solib_event): Add fallback link + namespace test for when the debug struct isn't available. + 2019-12-21 Eli Zaretskii * top.c (print_gdb_configuration): Print "--with-xxhash" or -- cgit v1.1
