      e4defrag: remove a lot of cruft · 4f1d0e86
      Eric Sandeen authored 
      
e4defrag.c had a lot of stuff copied into it from other
places, redefinitions of existing interfaces, etc.

We should be able to remove most of this, as the tool only
works on recent kernels anyway, we should just pick up
definitions from recent kernel headers whenever possible.

I've left the local definitions of fallocate, fadvise
(changed to posix_fadvise) and sync_file_range, and
wrapped them in #ifdef configure-time tests - though
really it seems like only fallocate should be necessary
by now, and perhaps the others can be dropped.

We still need some Makefile work so that it won't try to
build e4defrag if the right pieces aren't there (and
if the local definitions won't work...)

      Enhance build system so that "make V=1" works like the Linux Kernel · bcb915b0
      Theodore Ts'o authored 
      
If gmake is available, the developer can use "make V=1" instead of
using a configure-time switch, --enable-verbose-makecmds, to see all
of the commands executed by the Makefile.

      Add support for configure --enable-verbose-makecmds · c13351f6
      Theodore Ts'o authored 
      
Some people don't want to see the concise "kernel-style" make output.
This configure option allows build engines that want to see the full
set of commands executed by the makefile to get what they want.  Most
people will find this more distracting than useful, unless they need
to debug the Makefiles.

(It is not necessary to rerun configure to enable this verbose make
output temprarily; if a developer wants to do a quick debug of a
directory's makefile, he or she can simply edit the definition of the
$(E) and $(Q) variables in the Makefile; instructions can be found in
the MCONFIG file which is included in at the beginning of every
Makefile.)

      libcom_err: Use sem_post/sem_init to prevent race conditions · d7f45af8
      Theodore Ts'o authored 
      
SuSE has been carrying a patch for a long time to prevent a largely
theoretical race condition if a multi-threaded application adds and
removes error tables in multiple threads.  Unfortunately SuSE's
approach breaks compatibility by forcing applications to link and
compile with the -pthread option; using pthread mutexes has
historically been problematic.

This commit fixes things in a more portable way by using
sem_post/sem_wait instead, which is an older interface that doesn't
require the pthreads library.  Linux happens to implement
sem_post/sem_init using futexes, and -lrt ends up pulling in
-lpthread, but the advantage of using POSIX semaphores is that
applications don't have to be built using -pthread, unlike the use of
pthread mutexes.

The add_error_table() and remove_error_table() interfaces are the
preferred interfaces and locking protection have been added to only
these interfaces.  I have not added locking protection to the
generated initialize_xxx_error_table and initialize_xxx_error_table_r
interfaces, to avoid adding symbol dependencies that would cause a
library to fail to work when linking against older com_err libraries
that do not export et_list_lock() and et_list_unlock().  Threaded
applications shouldn't be using these interfaces in any case.

      Improve ELF shared library handling · 55da9876
      Theodore Ts'o authored 
      
Pass in -rpath-link option to the linker so that blkid will build
correctly on systems that don't have libcom_err.so.2 installed.

Fix debugfs to only try to link with -ldl when building without shared
libraries; with ELF shared libraries, the library which requires -ldl
(libss.so) can required the library dependency itself.

Fix how we build tune2fs.static so that we use @LDFLAG_STATIC@, via
$(LDFLAGS_STATIC), instead of hard-coding the use of -static.

      Remove default sizeof sizes in configure script when cross-compiling · b8251a54
      Maciej W. Rozycki authored 
      
Since version 2.50 autoconf fully supports checking sizes of types
(with AC_CHECK_SIZEOF) when cross-compiling.  Therefore there is no
need to preset the respective cache variables anymore.  The following
patch removes the special case.  There is no need to adjust AC_PREREQ
as it's set to 2.50 already.

Tested successfully cross-building for the mips64el-linux-gnu host on
an i386-linux-gnu build system, removing the following warning
(because of a mismatch for the "long" type):

Sizeof(__U64__TYPEDEF) is 4 should be 8

      Don't build e2fsck statically by default anymore · 7e8fe327
      Theodore Ts'o authored 
      
Also removed the --enable-dynamic-static configure option.

Unfortunately the usefulness of building e2fsck statically is gone on
all modern distributions, since everything else on the system is built
dynamically these days.  In fact on some distributions it is almost
impossible to build programs statically any more.

      Use pkg-config to determine where to find the devmapper library · a4ece359
      Theodore Ts'o authored 
      
Fedora and Red Hat puts the devmapper library in different locations
compared to Debian, so we use pkg-config.  Unfortunately Debian's
devmapper.pc file is buggy (See Debian Bug #390243), so we have to
work around it.

Historically, e2fsprogs has tried not to depend on pkg-config, since
its answers are so often **wrong** (the Debian bug has been ignored
for over a year), so I'm hoping I'm not going to regret this.

Add uuidd daemon to prevent duplicate time-based UUID's

Also store the clock sequence information in a state file in
/var/lib/misc/uuid-clock so that if the time goes backwards the clock
sequence counter can get bumped.  This allows us to completely
correctly generate time-based (version 1) UUID's according to the
algorithm specified RFC 4122.
