From 4caef86ca68a3fea8fab5398bedc5e0e6c0d222b Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 23 Jan 1999 22:17:17 +0000 Subject: Update. 1999-01-23 Ulrich Drepper * nss/nss_files/files-XXX.c (internal_getent): Make sure the buffer has at least two bytes (not one). Correct buflen parameter type. * nss/nss_files/files-alias.c (get_next_alias): Make sure buffer has at least two bytes. Use fgets_unlocked instead of fgets. * ctype/ctype.h: Don't user __tolower directly for tolower implementation. Use inline function which tests for the range first. Make _tolower equivalent to old tolower macros. Likewise for toupper. * ctype/ctype.c: Change tolower/toupper definition accordingly. * argp/argp-help.c: Use _tolower instead of tolower if possible. * inet/ether_aton_r.c: Likewise. * inet/ether_line.c: Likewise. * inet/rcmd.c: Likewise. * intl/l10nflist.c: Likewise. * locale/programs/ld-collate.c: Likewise. * locale/programs/linereader.c: Likewise. * locale/programs/localedef.c: Likewise. * nis/nss_nis/nis-alias.c: Likewise. * nis/nss_nis/nis-network.c: Likewise. * posix/regex.c: Likewise. * resolv/inet_net_pton.c: Likewise. * stdio-common/printf_fp.c: Likewise. * stdio-common/vfscanf.c: Likewise. * sysdeps/generic/strcasestr.c: Likewise. * math/bits/mathcalls.h: Fix typo. --- ChangeLog | 31 +++++++++++++++++++++++++++++++ argp/argp-help.c | 6 +++++- inet/ether_aton_r.c | 6 +++--- inet/ether_line.c | 6 +++--- inet/rcmd.c | 2 +- intl/l10nflist.c | 4 ++-- locale/programs/ld-collate.c | 12 ++++++------ locale/programs/linereader.c | 6 +++--- locale/programs/localedef.c | 2 +- math/bits/mathcalls.h | 2 +- nis/nss_nis/nis-alias.c | 4 ++-- nis/nss_nis/nis-network.c | 4 ++-- nss/nss_files/files-XXX.c | 6 +++--- nss/nss_files/files-alias.c | 14 ++++++++++---- posix/regex.c | 10 ++++++++-- resolv/inet_net_pton.c | 3 +-- stdio-common/printf_fp.c | 4 ++-- stdio-common/vfscanf.c | 34 +++++++++++++++++----------------- sysdeps/generic/strcasestr.c | 26 +++++++++++++------------- 19 files changed, 114 insertions(+), 68 deletions(-) diff --git a/ChangeLog b/ChangeLog index 976b1bb65b..064eb5cae9 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,34 @@ +1999-01-23 Ulrich Drepper + + * nss/nss_files/files-XXX.c (internal_getent): Make sure the buffer has + at least two bytes (not one).
