build-many-glibcs: don't crash if email is not configured

2017-02-17T00:04:11+00:00

The 'bot-cycle' action for build-many-glibcs is a convenient way to
not have to remember all the steps in keeping a many-glibcs tree up
to date ... or it would be, if the script could send mail _optionally_.
Make it so by skipping the mail step if mail isn't configured.

	* scripts/build-many-glibcs.py (bot_build_mail):  If the
	bot_config does not contain all of the necessary email-
	related settings, just print a warning and continue.

tunables: Fix environment variable processing for setuid binaries (bz #21073)

2017-02-02T10:20:16+00:00

Florian Weimer pointed out that we have three different kinds of
environment variables (and hence tunables):

1. Variables that are removed for setxid processes
2. Variables that are ignored in setxid processes but is passed on to
   child processes
3. Variables that are passed on to child processes all the time

Tunables currently only does (2) and (3) when it should be doing (1)
for MALLOC_CHECK_.  This patch enhances the is_secure flag in tunables
to an enum value that can specify which of the above three categories
the tunable (and its envvar alias) belongs to.

The default is for tunables to be in (1).  Hence, all of the malloc
tunables barring MALLOC_CHECK_ are explicitly specified to belong to
category (2).  There were discussions around abolishing category (2)
completely but we can do that as a separate exercise in 2.26.

Tested on x86_64 to verify that there are no regressions.

	[BZ #21073]
	* elf/dl-tunable-types.h (tunable_seclevel_t): New enum.
	* elf/dl-tunables.c (tunables_strdup): Remove.
	(get_next_env): Also return the previous envp.
	(parse_tunables): Erase tunables of category
	TUNABLES_SECLEVEL_SXID_ERASE.
	(maybe_enable_malloc_check): Make MALLOC_CHECK_
	TUNABLE_SECLEVEL_NONE if /etc/setuid-debug is accessible.
	(__tunables_init)[TUNABLES_FRONTEND ==
	TUNABLES_FRONTEND_valstring]: Update GLIBC_TUNABLES envvar
	after parsing.
	[TUNABLES_FRONTEND != TUNABLES_FRONTEND_valstring]: Erase
	tunable envvars of category TUNABLES_SECLEVEL_SXID_ERASE.
	* elf/dl-tunables.h (struct _tunable): Change member is_secure
	to security_level.
	* elf/dl-tunables.list: Add security_level annotations for all
	tunables.
	* scripts/gen-tunables.awk: Recognize and generate enum values
	for security_level.
	* elf/tst-env-setuid.c: New test case.
	* elf/tst-env-setuid-tunables: new test case.
	* elf/Makefile (tests-static): Add them.

Avoid parallel GCC install in build-many-glibcs.py.

2017-01-18T23:13:09+00:00

A recent build-many-glibcs.py build
 ran
into what proves to be an old known bug
 with parallel
install of GCC (one which as discussed there might require automake
changes to fix).  This patch makes build-many-glibcs.py avoid such
intermittent failures from parallel install by using -j1 for GCC make
install (the code in question also applies to binutils make install,
but it doesn't seem worth trying to avoid -j1 there; the builds and
installs of different toolchains are still fully parallel with each
other, this is only about the case when there are few enough of those
that multiple jobs can get used within a single make install).

	* scripts/build-many-glibcs.py (Config.build_cross_tool): Use -j1
	for make install.

Make build-many-glibcs.py work on python3.2

2017-01-11T12:30:40+00:00

I used this patch to run the new build script with python3.2, it may be worth
adding this hack if python3.5 is not widespread (might work with older python,
i haven't tested that).

This patch make build-many-glibcs.py work with python 3.2 by
adding fallback implementation to python 3.5 facilities if they
are not present.

Checked building a x86_64-linux-gnu toolchain with python 3.2.

2016-11-22  Szabolcs Nagy  

	* scripts/build-many-glibcs.py (os.cpu_count): Add compatibility definition.
	(re.fullmatch, subprocess.run): Likewise.

Add build-many-glibcs.py powerpc-linux-gnu-power4 build.

2017-01-02T22:13:42+00:00

The 32-bit powerpc configurations in build-many-glibcs.py were failing
to cover the powerpc32 multiarch code at all, because that code is
only built for power4 and above configurations.  This patch adds a
32-bit power4 configuration so that at least some of that multiarch
code gets build-tested.  (This is preparation for reviewing the w_*
file renaming, which affects such powerpc32 multiarch files.)

	* scripts/build-many-glibcs.py (Context.add_all_configs): Add
	power4 glibc for powerpc-linux-gnu.

Make build-many-glibcs.py use binutils 2.28 branch by default.

2017-01-02T13:30:03+00:00

Now that a release branch exists for binutils 2.28, this patch makes
build-many-glibcs.py use that by default in place of 2.27.

	* scripts/build-many-glibcs.py (Context.checkout): Default
	binutils version to 2.28 branch.

Update config.guess and config.sub to current versions.

2017-01-01T00:29:55+00:00

	* scripts/config.guess: Update to version 2017-01-01.
	* scripts/config.sub: Update to version 2017-01-01.

Update copyright dates not handled by scripts/update-copyrights.

2017-01-01T00:26:24+00:00

I've updated copyright dates in glibc for 2017.  This is the patch for
the changes not generated by scripts/update-copyrights and subsequent
build / regeneration of generated files.

Please remember to include 2017 in the dates for any new files added
in future (which means updating any existing uncommitted patches you
have that add new files to use the new copyright dates in them).

Update DNS RR type definitions [BZ #20593]

2016-12-31T20:16:27+00:00

This commit includes a new script which allows generating parts of
the header files from IANA DNS parameters protocol registry.
