Fri Jun 28 02:41:08 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>cvs/libc-960628
* nss/Makefile (databases): New variable. (routines, libnss_files-routines): Use it. (subdir-dirs): Compute from $(services). * sysdeps/unix/sysv/linux/syscalls.list (create_module, delete_module, init_module, klogctl): Use EXTRA in the "caller" column so these get added to unix-extra-syscalls and thus compiled in misc. * string/Makefile (routines): Add strndup. * string/strndup.c: New file. * string/string.h: Declare strndup. (strndupa): New macro. * string/string.h: Declare __strdup. * string/strdup.c: Deansideclized. Define __ name and weak alias. * string/string.h: Don't define memccpy as macro for [__OPTIMIZE__]. Thu Jun 27 23:43:22 1996 Richard Henderson <rth@tamu.edu> * sysdeps/alpha/dl-machine.h (elf_machine_rela): The Alpha's address-of operation and plt format conspire to require all dynamic relocs to be resolved to actual symbols not plt entries. Thu Jun 27 02:49:28 1996 Ulrich Drepper <drepper@cygnus.com> * catgets/gencat.c: Add casts to avoid signed<->unsigned warnings. * grp/initgroups.c (initgroups): De-ansi-fy. Move declaration of NGROUPS and GROUPS outside #if so that the code compiles for NGROUPS_MAX != 0. * inet/Makefile (headers): Add netinet/ether.h and netinet/if_ether.h. (routines): Add ether_aton, ether_aton_r, ether_hton, ether_line, ether_ntoa, ether_ntoa_r, and ether_ntoh. * inet/ether_aton.c, inet/ether_aton_r.c, inet/ether_hton.c, inet/ether_line.c, inet/ether_ntoa.c, inet/ether_ntoa_r.c, inet/ether_ntoh.c: New files. Implementation of functions to handle Ethernet address to host mapping. * inet/netinet/ether.h: New file. Declare ether_* functions. * netinet/ether.h: Wrapper around inet/netinet/ether.h for glibc compilation. * nss/ethers-lookup.c: New file. Lookup function for ethers database. * nss/Makefile (routines): Add ethers-lookup. (libnss_files-routines): Add files-ethers. * nss/getXXent_r.c: Don't define set*ent and end*ent function with _r suffix. * nss/nss_files/files-XXX.c (internal_endent): Don't reset KEEP_STREAM every time called. (_nss_files_end): Reset KEEP_STREAM here instead. (internal_getent): If STREAM == NULL try to open instead of signalling error. Use cast to prevent warning. Terminate read line in case the buffer is too small. * nss/nss_files/files-ethers.c: New file. Implementation of Ethernet adress<->hostname lookup through files interface. * stdlib/mbstowcs.c: Define based on mbsrtowcs(). * stdlib/mbtowc.c: Define based on mbrtowc(). * stdlib/wcstombs.c: Define based on wcsrtombs(). * stdlib/wctomb.c: Define based on wcrtomb(). * sunrpc/xdr.c (xdr_u_int): Avoid bogus call to unexpected_sizes_in_xdr_u_int. * sysdeps/generic/netinet/if_ether.h: New file. Generic declaration of `struct ether_addr'. * sysdeps/unix/sysv/linux/netinet/if_ether.h: New file. Linux specific declaration of `struct ether_addr'. * wcsmbs/mbrtowc.c: Handle case where argument PS is NULL. * wcsmbs/mbsrtowcs.c: Ditto. * wcsmbs/wcrtomb.c: Ditto. * wcsmbs/wcsrtombs.c: Ditto. * wcsmbs/mbsinit.c: Prepare for PS being NULL.
