+ (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.

+ 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.

+ (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).

+ * 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.
