Fix non-Linux builds

2022-11-29T13:10:22+00:00

Various tools are Linuxish and should thus only attempted to build on Linux only. Some features are also Linux-only. Also, libresolv is used on all GNU platforms, notably GNU/Hurd and GNU/kfreeBSD. Signed-off-by: Samuel Thibault Signed-off-by: Denys Vlasenko

ifplugd: split -a into -a and -A, latter disables upping in iface creation

2022-04-30T12:33:14+00:00

-a meant both "don't up iface before each link detection" and "don't up iface when it newly appears". But they are not the same. I have a dock station where eth1 appears when I attach the notebook to it (looks like it's hanging off a USB bus). IOW: appearance of this interface is functionally equivalent to attaching ethernet cable. ifplugd meant to be able to *automatically* handle this case. Currently, with -a, it couldn't: newly appearing iface stayed down, user had to manually up it. function old new delta packed_usage 34253 34296 +43 .rodata 104876 104877 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 44/0) Total: 44 bytes Signed-off-by: Denys Vlasenko

build system: drop PLATFORM_LINUX

2020-08-13T15:12:56+00:00

PLATFORM_LINUX is a hidden configuration option which is disabled by default and enabled at over a hundred locations for features that are deemed to be Linux specific. The only effect of PLATFORM_LINUX is to control compilation of libbb/match_fstype.c. This file is only needed by mount and umount. Remove all references to PLATFORM_LINUX and compile match_fstype.c if mount or umount is enabled. Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko

libbb: reduce the overhead of single parameter bb_error_msg() calls

2019-07-02T09:35:03+00:00

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.
