| | | | | | | | | | | | | | | | FreeBSD is not using <utmp.h> and does not define _PATH_UTMPX. Tested with busybox applets depending on FEATURE_UTMP (e.g. who, users, etc) Signed-off-by: Alex Samorukov <samm@os2.kiev.ua> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Unlike util-linux mount, busybox never supported the sizelimit option but simply forwards it to the kernel. Since v5.4 mounting will fail with squashfs: Unknown parameter 'sizelimit' Support the sizelimit parameter by setting it in the LOOP_SET_STATUS64 structure before handing it to the kernel. While at it also add support for the offset option, which currently will always be set to 0. function old new delta cut_out_ull_opt - 167 +167 singlemount 1230 1266 +36 set_loop 834 862 +28 losetup_main 479 483 +4 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 3/0 up/down: 235/0) Total: 235 bytes Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| * libbb: reduce the overhead of single parameter bb_error_msg() callsJames Byrne2019-07-021-1/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in 2007, commit 0c97c9d43707 ("'simple' error message functions by Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower overhead call to bb_perror_msg() when only a string was being printed with no parameters. This saves space for some CPU architectures because it avoids the overhead of a call to a variadic function. However there has never been a simple version of bb_error_msg(), and since 2007 many new calls to bb_perror_msg() have been added that only take a single parameter and so could have been using bb_simple_perror_message(). This changeset introduces 'simple' versions of bb_info_msg(), bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and bb_herror_msg_and_die(), and replaces all calls that only take a single parameter, or use something like ("%s", arg), with calls to the corresponding 'simple' version. Since it is likely that single parameter calls to the variadic functions may be accidentally reintroduced in the future a new debugging config option WARN_SIMPLE_MSG has been introduced. This uses some macro magic which will cause any such calls to generate a warning, but this is turned off by default to avoid use of the unpleasant macros in normal circumstances. This is a large changeset due to the number of calls that have been replaced. The only files that contain changes other than simple substitution of function calls are libbb.h, libbb/herror_msg.c, libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c, networking/udhcp/common.h and util-linux/mdev.c additonal macros have been added for logging so that single parameter and multiple parameter logging variants exist. The amount of space saved varies considerably by architecture, and was found to be as follows (for 'defconfig' using GCC 7.4): Arm: -92 bytes MIPS: -52 bytes PPC: -1836 bytes x86_64: -938 bytes Note that for the MIPS architecture only an exception had to be made disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h) because it made these files larger on MIPS.

The downside of this is that daemons now log all messages to syslog at the LOG_ERR level which makes it hard to filter errors from informational messages. This change optionally re-introduces bb_info_msg(), controlled by a new option FEATURE_SYSLOG_INFO, restores all the calls to bb_info_msg() that were removed (only in applets that set logmode to LOGMODE_SYSLOG or LOGMODE_BOTH), and also changes informational messages in ifplugd and ntpd.

* | win32: make stat(2) fetch additional metadataRon Yorston2019-02-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the WIN32 implementation of stat(2) to fetch inode number, device id and number of hardlinks. This requires opening a handle to the target file so it will be slower. A number of features can be enabled or start to work: - tar can detect if an archive is being stored in itself; - find can support the -inum and -links options; - ls can display inode numbers; - diff can detect attempts to compare a file with itself; - du has better support for hardlinked files; - cp can detect attempts to copy a file over itself.

| * start-stop-daemon: create pidfile before parent exits, closes 8596Denys Vlasenko2019-01-141-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes DAEMON_DOUBLE_FORK flag from bb_daemonize_or_rexec(), as SSD was the only user. Also includes fix for -S: now works without -a and -x, does not print pids (compat with "start-stop-daemon (OpenRC) 0.34.11 (Gentoo Linux)"). function old new delta start_stop_daemon_main 1018 1084 +66 add_interface 99 103 +4 fail_hunk 139 136 -3 bb_daemonize_or_rexec 205 183 -22 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/2 up/down: 70/-25) Total: 45 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
