From abee3d0e0dc7c7e4b733b0145c56bf8159a37a69 Mon Sep 17 00:00:00 2001 From: Denis Vlasenko Date: Wed, 26 Dec 2007 20:44:45 +0000 Subject: Fix xmalloc_fgets_str so that it really does NOT strip terminator. Add xmalloc_fgetline_str which does strip terminator, and use it in dpkg instead of xmalloc_fgets_str. netstat: use xmalloc_fgets_str - allows to eat strings with NULs (this fixes bug with some weird /proc/net/unix input) function old new delta xmalloc_fgets_internal - 191 +191 xmalloc_fgetline_str - 18 +18 do_info 116 120 +4 unix_do_one 451 447 -4 tcp_do_one 423 419 -4 send_tree 369 365 -4 xmalloc_fgets_str 178 15 -163 ------------------------------------------------------------------------------ (add/remove: 2/0 grow/shrink: 1/4 up/down: 213/-175) Total: 38 bytes text data bss dec hex filename 778445 832 7344 786621 c00bd busybox_old 778483 832 7344 786659 c00e3 busybox_unstripped --- include/libbb.h | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'include') diff --git a/include/libbb.h b/include/libbb.h index 2b92821..1da37ed 100644 --- a/include/libbb.h +++ b/include/libbb.h @@ -464,9 +464,12 @@ extern void xwrite(int fd, const void *buf, size_t count); /* Reads and prints to stdout till eof, then closes FILE.
