2021-06-05build system: use SOURCE_DATE_EPOCH for timestamp if availablePaul Spooren
The SOURCE_DATE_EPOCH is an effort of the Reproducible Builds organization to make timestamps/build dates in compiled tools deterministic over several repetitive builds. Busybox shows by default the build date timestamp which changes whenever compiled. To have a reasonable accurate build date while staying reproducible, it's possible to use the *date of last source modification* rather than the current time and date. Further information on SOURCE_DATE_EPOCH are available online [1]. This patch modifies `confdata.c` so that the content of the SOURCE_DATE_EPOCH env variable is used as timestamp. To be independent of different timezones between builds, whenever SOURCE_DATE_EPOCH is defined the GMT time is used.

2021-06-05shell: also do word splitting when -d DELIM is usedEicke Herbertz
The original commit 3bef5d89b0 introduced an additional check for an unset `opt_d` before doing word splitting. I'm unsure why it's there in the first place, but the commit message also describes a different behaviour than what -d actually does in bash, while the code mostly does the right thing. `opt_d` sets the line delimiter for read to stop reading and should not affect word splitting.

2021-06-05gen_build_files: Use C locale when calling sed on globbed filesKhem Raj
When include/applets.h is re-generated it generates code macros in include/applets.h e.g. IF_XZCAT(APPLET_ODDNAME(xzcat, unxz, BB_DIR_USR_BIN, BB_SUID_DROP, xzcat)) ... IF_CHVT(APPLET_NOEXEC(chvt, chvt, BB_DIR_USR_BIN, BB_SUID_DROP, chvt)) ... sed is used to process source files like below to feed into this header generation sed -n 's@^//applet:@@p' "$srctree"/*/*.c "$srctree"/*/*/*.c this means we let shell decide the order of .c files being fed into sed tool, applets.h has code snippets thats generated out of code fragments from these .c files and the order of the generated code depends on the order of .c files being fed to sed and then piped to generate tool, even though the generated code is logically same, it does result in re-odered code in applets.h based on which shell was used during build on exact busybox sources since sort order is different based on chosen locale and also default shell being bash or dash This sets the environment variable LC_ALL to the value C, which will enforce bytewise sorting, irrespective of the shell Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-06-05udhcpc: revert deprecation message for -VDenys Vlasenko
"-x vendor:VENDOR" will not be a trivial replacement of it: (1) by default, we do send a vendor string ("udhcp BB_VER"), will need code to preserve the default. (2) -V '' currently disables vendor string. -x vendor:'' would not easily achieve that: it adds no option at all (string options can't be empty), and default (1) would trigger. To avoid that, we will need yet another hack to detect -x vendor:'' and interpret that as "no vendor string at all".

2021-06-04ls: don't output any colors with TERM=dumbSören Tempel
The TERM variable is usually set to "dumb" to indicate that the terminal does not support any ANSI escape sequences. Presently, ls does not honor this variable and outputs colors anyhow which results in unreadable output, unless the user explicitly disables colors using `ls --color=never`. The rational behind this change is that ls should "just work" by default, even on dumb terminals. For this reason, this patch adds a check which additionally consults the TERM variable before printing any colors. This is analogous to the existing check for ensuring that standard output is a tty. As such, colors can still be forced with `--color=force`, even if TERM is set to dumb. function old new delta is_TERM_dumb - 40 +40 ls_main 579 598 +19 .rodata 103246 103251 +5 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/0 up/down: 64/0) Total: 64 bytes Signed-off-by: Sören Tempel <soeren+git@soeren-tempel.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-06-03udhcpd: don't hardcode treating .0 and .255 speciallySeth David Schoen
Even following current Internet standards, it can be perfectly legitimate to issue IPv4 addresses that end in .0 or .255 via DHCP -- this can happen whenever the network is larger than /8. For example, 10.3.4.0 and 10.3.4.255 are legitimate host addresses in 10/8 or 10.3/16. (We also want to be able to issue .0 addresses in smaller networks following our proposed kernel patch and standards changes.) This behavior is already fully controllable by the user, simply by setting start_ip and end_ip correctly. Users who don't want to issue .0 or .255 should set start_ip greater than .0 or end_ip less than .255 and udhcpd will already respect these bounds. (This is also the case for other DHCP servers -- the recommended example configurations will default to a lower bound starting with .1 or some other value, which is typically appropriate, but the user is still allowed to change this to .0 -- or to a range that overlaps a .0 or .255 address -- if so desired.)

2021-06-02vi: remove autoindent from otherwise empty linesRon Yorston
Lines that have no content apart from automatic indentation should be treated as empty when the user hits return or ESC. The implementation uses the global variable 'indentcol'. Usually this is zero. It can also be -1 to indicate an 'O' (open above) command, replacing the overloading of the tabstop option bit. A value greater than zero indicates that the current line has been autoindented to the given column (or that the autoindent has been adjusted with ctrl-D). Any other change to the line resets 'indentcol' to zero. Replace strspn() with ident_len(). The latter handles the unlikely case that it's called on the last line of a file which doesn't have a terminating newline. function old new delta char_insert 741 912 +171 indent_len - 42 +42 do_cmd 4781 4785 +4 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/0 up/down: 217/0) Total: 217 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
