Description Carlos O'Donell 2020-08-23 02:13:08 UTC

Backport the following commits to improve the dynamic loader:

ad78d702757a189b1fa552d607e8aaa22252a45f
elf: Remove redundant add_to_global_resize_failure  call from dl_open_args

7b5bfe77836442b9aeb75cc520f0d1eb7f82be67
elf: Assert that objects are relocated before their constructors run

3ad5dab476205d6e16156cf0511fa6884b3b0fc4
elf: Do not signal LA_ACT_CONSISTENT for an empty namespace [BZ #26076]

Comment 5 Carlos O'Donell 2022-01-28 14:52:16 UTC

The first commit was backported as part of the fixes for the dl-tls.c assert issue (Bug 1991001).
The second commit is not really required since the assert hasn't triggered in a long time (belt-and-suspenders).
The third commit will come in with the LD_AUDIT fixes when they are completed upstream.

I'm closing out this proactive backport bug for ld.so improvements.
