Message-Id: <1464842814-30690-1-git-send-email-vapier@gentoo.org> Date: Thu, 2 Jun 2016 00:46:54 -0400 From: Mike Frysinger <vapier@...too.org> To: YOSHIFUJI Hideaki <yoshfuji@...ux-ipv6.org> Cc: netdev@...r.kernel.org Subject: [PATCH iputils v2] ping: always accept . delimiter with -i number parsing Always allow #.# format for the -i flag even when the current locale uses a different separator. Locale de_DE which uses #,# normally. Simple testcase: $ make USE_IDN=1 $ LANG=de_DE.UTF8 ./ping -i 0.5 localhost $ LANG=de_DE.UTF8 ./ping -i 0,5 localhost Reported-by: Sergey Fionov <fionov@...il.com> Signed-off-by: Mike Frysinger <vapier@...too.org> --- ping_common.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) diff --git a/ping_common.c b/ping_common.c index 62f53a6..6054a91 100644 --- a/ping_common.c +++ b/ping_common.c @@ -269,11 +269,28 @@ void common_options(int ch) double dbl; char *ep; +#ifdef USE_IDN + int try_c_loc = 0; + retry_c_loc: +#endif + errno = 0; dbl = strtod(optarg, &ep); +#ifdef USE_IDN + if (try_c_loc) + setlocale(LC_ALL, ""); +#endif + if (errno || *ep != '\0' || !finite(dbl) || dbl < 0.0 || dbl >= (double)INT_MAX / 1000 - 1.0) { +#ifdef USE_IDN + if (!try_c_loc) { + try_c_loc = 1; + setlocale(LC_ALL, "C"); + goto retry_c_loc; + } +#endif fprintf(stderr, "ping: bad timing interval\n"); exit(2); } -- 2.8.2
