Subject: [PATCH v4 0/2] implement dlmem() function
Date: Tue, 14 Feb 2023 13:41:21 +0500	[thread overview]
Message-ID: <20230214084123.2056067-1-stsp2@yandex.ru> (raw)

Changes in v4:
- re-target to GLIBC_2.38
- add tst-auditdlmem.c test-case to test auditing
- drop length page-aligning in tst-dlmem: mmap() aligns length on its own
- bugfix: in do_mmapcpy() allow mmaps past end of buffer

Changes in v3:
- Changed prototype of dlmem() (and all the internal machinery) to
  use "const unsigned char *buffer" instead of "const char *buffer".

Changes in v2:
- use <support/test-driver.c> instead of "../test-skeleton.c"
- re-target to GLIBC_2.37
- update all libc.abilist files


Patch 1: fix memory management bug in _dl_new_object()
Patch 2: implement dlmem() itself

  elf: strdup() l_name if no realname [BZ #30100]
  dlfcn,elf: implement dlmem() function [BZ #11767]
