Tue Jan 21 04:05:20 1997  Ulrich Drepper  <drepper@cygnus.com>

	* version.h (VERSION): Bump to 1.101.

	Implement -d and -r option to `ldd' to check relocations.
	* elf/dl-error.c: Add another method to intercept errors.
	(_dl_receive_error): New function.  Install user defined handler.
	(receiver): New variable.  Contains pointer to user provided handler.
	(_dl_signal_error): If user provided handler is installed call this.
	* elf/dl-load.c (_dl_map_object): When shared object is not found in
	trace mode initialize a few more fields so that lookup can actually
	happen but always fails.
	* elf/ldd.sh.in: Rewrite argument handling.  Recognize new arguments
	to trigger reloation test.  Return with appropriate error code if
	a file wasn't found.  Print warning if object is not executable.
	* elf/ldd.bash.in: Likewise.
	* elf/link.h (receiver_fct): New type.  Used in _dl_receive_error.
	(_dl_sysdep_error): New prototype.

	* elf/rtld.c (dl_main): Rewrite argument handling.  More than
	one argument allowed.  Recognize --data-relocs and --function-relocs
	arguments.
	Don't determine `lazy' mode from LD_BIND_NOW environment variable
	when in trace mode.
	If in trace mode and either --data-relocs or --function-relocs is
	given perform relocation.  Report errors using print_unresolved
	function.
	(print_unresolved): New function.  Print information about missing
	symbol on stderr.
	* sysdeps/generic/dl-sysdep.c (_dl_sysdep_error): New function.
	Like _dl_sysdep_message but print to stderr.
	* sysdeps/mach/hurd/dl-sysdep.c: Likewise.

	* sysdeps/generic/sockaddrcom.h: Add definition of sa_family_t.
	Reported by Andreas Schwab.
	(__SOCKADDR_COMMON): Use sa_family_t for family member.
	* sysdeps/unix/bsd/bsd4.4/sockaddrcom.h: Likewise.

	Linux/Sparc support by Miguel de Icaza.
	* sysdeps/sparc/fpu_control.h: New file.

	* sysdeps/unix/sysv/linux/sparc/Makefile: New file.

	* sysdeps/unix/sysv/linux/net/if_arp.h: Don't use kernel header.
	Provide own definition based on 4.4BSD and Linux.
	* sysdeps/unix/sysv/linux/net/ppp_defs.h: Define __u32 before
	including <linux/ppp_defs.h>.
	* sysdeps/unix/sysv/linux/sys/msq_buf.h (struct msqid_ds): Don't
	use __pid_t since the kernel might have a different size.
	* sysdeps/unix/sysv/linux/sys/shm_buf.h (struct shmid_ds): Likewise.
	Reported by Andreas Schwab.

	* time/asctime.c: Update copyright.
	* time/dysize.c: Likewise.
	* time/gmtime.c: Likewise.
	* time/timegm.c: Likewise.
	* time/offtime.c: Likewise.  De-ANSI-declfy.

	* time/tzset.c (__tzset_internal): When TZ envvar does not name a
	DST timezone don't default to offset -1.

	* sysdeps/unix/sysv/linux/net/route.h: Don't use kernel header.
	Reported by a sun <asun@zoology.washington.edu>.

	* resolv/Makefile: Correct spelling: subdirs-dirs -> subdir-dirs.

	* sysdeps/stub/sysv_signal.c: New file.  Stub implementation.

	* Makefile (distribute): Add mcheck.h.

	* nis/Makefile (distribute): Add nss-nis.h.

	* libio/Makefile (routines): Change vdprintf to iovdprintf to prevent
	dist problem.

	.popsection in the assembler.
	* config.h.in: Add HAVE_ASM_PREVIOUS_DIRECTIVE and
	HAVE_ASM_POPSECTION_DIRECTIVE.
	* libc-symbols.h (__make_section_unallocated) [HAVE_ELF]: Define
	appropriate if either .previous or .popsection is supported.
	(libc_warning) [HAVE_ELF]: Use it here.

Sat Jan 18 22:15:26 1997  Richard Henderson  <rth@tamu.edu>

	* Makeconfig (CFLAGS-.so): Add -fno-common to prevent odd sorts of
	errors that can occur when linking libc.so.

Mon Jan 20 05:20:49 1997  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dl-load.c (open_path): When running setuid don't try
	a directory if it is not given with the full name.

	* elf/Makefile (before-compile): New variable.  Mention trusted-dirs.h.
	(trusted-dirs.h): Construct file from $(default-rpath) and
	$(user-defined-trusted-dirs) variables.
	* elf/dl-load.c (_dl_map_object): Pass additional argument to open_path
	which is NULL except for the LD_LIBRARY_PATH pass in which case it
	is a pointer to the list of directories from the trusted-dirs.h
	file.
	(open_path): Accept additional argument with list of trusted dirs.
	When running setuid and a list of trusted dirs is given only use
	those which are mentioned in the list.

	* elf/rtld.c (dl_main): Don't reject whole LD_LIBRARY_PATH when
	running setuid.  Instead accept entries which do not contain a '/'.

	* Makeconfig: Correct comment about +(default_cflags).

Mon Jan 20 05:11:14 1997  Hrvoje Niksic  <hniksic@srce.hr>

	* time/strptime.c (recursive): Use && not || to test for valid
	argument.

Mon Jan 20 05:06:50 1997  Ulrich Drepper  <drepper@cygnus.com>

	* elf/ldd.sh.in: Exit with value 1 if an error occured.
	* elf/ldd.bash.in: Likewise.

	* elf/rtld.c (dl_main): Do not always ignore LD_PRELOAD when the
	binary runs setuid.  It is save to use those entries which do not
	contain a '/'.  This is compatible with Solaris-2.
