One of the implicit-fallthrough warnings from compiling glibc with
-Wextra appears to indicate an actual bug: the test-container code
could fall through inappropriately if execlp returns (which only
occurs on error). This patch adds appropriate error handling in this
case to avoid that fall-through.
Tested for x86_64.
* support/test-container.c (recursive_remove): Use FAIL_EXIT1 if
execlp returns.
|
|
* All files with FSF copyright notices: Update copyright dates
using scripts/update-copyrights.
* locale/programs/charmap-kw.h: Regenerated.
* locale/programs/locfile-kw.h: Likewise.

During postclean.req testing it was found that the fork in the
parent process (after the unshare syscall) would fail with ENOMEM
(see recursive_remove() in test-container.c). While failing with
ENOMEM is certainly unexpected, it is simply easier to refactor
the design and have the parent remain outside of the namespace.
This change moves the postclean.req processing to a distinct
process (the parent) that then forks the test process (which will
have to fork once more to complete uid/gid transitions). When the
test process exists the cleanup process will ensure all files are
deleted when a post clean is requested.

[BZ #23948]
* support/test-container.c: Move postclean step to before we
change namespaces.

* support/test-container.c (check_for_unshare_hints): New.
(main): Call it if unshare fails. Add support for "su" scriptlet
command.

The test-container.c file assumes that ld.so is always named
something like /elf/ld-linux-*.
But e.g. on s390x it is named ld64.so.1 or ld.so.1 on s390.
There are other architectures like power or mips with similar names.
This patch introduces the new global variable support_objdir_elf_ldso
which contains the absolute path to the runtime linker used by the
testsuite, e.g. OBJDIR_PATH/elf/ld-linux-x86-64.so.2.
The check in test-container.c is now comparing against this path.
Without this patch, test-container.c is searching invalid files / directories
and fails to find glibc/nss/tst-nss-test3.root/tst-nss-test3.script.
Then the test tst-nss-test3 fails!

* support/support_paths.c (support_objdir_elf_ldso): Likewise.
* support/Makefile (CFLAGS-support_paths.c): Add definition
for OBJDIR_ELF_LDSO_PATH.
* support/test-container.c (main): Search for the ld.so
which is also used by the testsuite.

copy_file_range can't be used to copy a file from glibc source directory
to glibc build directory since they may be on different filesystems.
This patch adds xcopy_file_range for cross-device copy.
