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. (_dl_receive_error): New prototype. (_dl_signal_error): Remove __attribute__ ((__noreturn__)). * 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/__sigtrampoline.S: New file. * sysdeps/unix/sysv/linux/sparc/brk.c: New file. * sysdeps/unix/sysv/linux/sparc/profil-counter.h: New file. * sysdeps/unix/sysv/linux/sparc/sigaction.c: New file. * sysdeps/unix/sysv/linux/sparc/socket.S: New file. * sysdeps/unix/sysv/linux/sparc/syscall.S: New file. * sysdeps/unix/sysv/linux/sparc/sysdep.h: New file. * sysdeps/unix/sysv/linux/sparc/Dist: New file. * sysdeps/unix/sysv/linux/sparc/Makefile: New file. * sysdeps/unix/sysv/linux/net/if_arp.h: Don't use kernel header.

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. * nss/Makefile (distribute): Add digits_dots.c. * sysdeps/unix/sysv/linux/Dist: Add kernel_sigaction.h. * sysdeps/unix/sysv/linux/alpha/Dist: Add sys/procfs.h. * sysdeps/unix/sysv/linux/sparc/Dist: Add clone.S. * new-malloc/Makefile (distribute): Add mcheck-init.c and mcheck.h. Mon Jan 20 17:54:28 1997 Sven Verdoolaege <skimo@breughel.ufsia.ac.be> * manual/filesys.texi: Fix little problem (reentrant->readdir). Fri Jan 17 19:07:07 1997 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * configure.in [$elf=yes]: Check for support of .previous and .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.
