Remove stime backport. Remove static libgcc patch as upstream fixed it with BUSYBOX_DEFAULT_STATIC_LIBGCC which defauls to off. Remove date -k patch as it no longer applies. It's also pointless as busybox' hwclock utility can do the same thing. Remove ntpd patch as that seems to have been applied upstream. Add smalll patch fixing compilation with SELinux. Upstream commit 2496616b0a8d1c80cd1416b73a4847b59b9f969a renamed the variable without renaming it in the SELinux path. Refresh config and patches. Config refresh: Refresh commands, run after busybox is first built once: cd package/utils/busybox/config/ ../convert_menuconfig.pl ../../../../build_dir/target-mips_24kc_musl/busybox-default/busybox-1.33.0 cd .. ./convert_defaults.pl < ../../../build_dir/target-mips_24kc_musl/busybox-default/busybox-1.33.0/.config > Config-defaults.in Manual edits needed afterward: * Config-defaults.in: OpenWrt config symbol IPV6 logic applied to BUSYBOX_DEFAULT_FEATURE_IPV6 * Config-defaults.in: OpenWrt configTARGET_bcm53xx logic applied to BUSYBOX_DEFAULT_TRUNCATE (commit547f1ec
) * editors/Config.in: Add USE_GLIBC dependency to BUSYBOX_CONFIG_FEATURE_VI_REGEX_SEARCH (commitf141090
) * shell/Config.in : change at "Options common to all shells" the symbol SHELL_ASH --> BUSYBOX_CONFIG_SHELL_ASH (discussion in http://lists.openwrt.org/pipermail/openwrt-devel/2021-January/033140.html Apparently our script does not see the hidden option while prepending config options with "BUSYBOX_CONFIG_" which leads to a missed dependency when the options are later evaluated.) * Edit Config.in files by adding quotes to sourced items in config/Config.in, networking/Config.in and util-linux/Config.in (commit1da014f

individual config item for them.

If you have a really tiny busybox with few applets enabled (and

bunzip2 isn't one of them), the overhead of the decompressor might

With this option you can install the busybox binary belonging

root-level operations even when run by ordinary users

With this option enabled, busybox drops privileges for applets

that don't need root access, before entering their main() function.
|
|
|
|
If you are really paranoid and don't want even initial busybox code
|
|
to run under root for every applet, build two busybox binaries with
|
|
different applets in them (and the appropriate symlinks pointing
|
|
to each binary), and only set the suid bit on the one that needs it.
|
|
|
|
Some applets which require root rights (need suid bit on the binary
|
|
or to be run by root) and will refuse to execute otherwise:
|
|
crontab, login, passwd, su, vlock, wall.
|
|
|
|
The applets which will use root rights if they have them
|
|
(via suid bit, or because run by root), but would try to work
|
|
without root right nevertheless:
|
|
findfs, ping[6], traceroute[6], mount.
|
|
|
|
Note that if you DO NOT select this option, but DO make busybox

security hole (think "cp /some/file /etc/passwd").

### help
|
|
### Normally each source-file is compiled with one invocation of
|
|
### the compiler.
|
|
### If you set this option, all sources are compiled at once.
|
|
### This gives the compiler more opportunities to optimize which can
|
|
### result in smaller and/or faster binaries.
|
|
###
|
|
### Setting this option will consume alot of memory, e.g. if you
|
|
### enable all applets with all features, gcc uses more than 300MB
|
|
### RAM during compilation of busybox.
|
|
###
|
|
### This option is most likely only beneficial for newer compilers
|
|
### such as gcc-4.1 and above.

The compiler's optimization of source code can eliminate and reorder

code, resulting in an executable that's hard to understand when

dmalloc support:
|
|
----------------
|
|
This enables compiling with dmalloc ( http://dmalloc.com/ )
|
|
which is an excellent public domain mem leak and malloc problem
|
|
detector. To enable dmalloc, before running busybox you will
|
|
want to properly set your environment, for example:
|
|
export DMALLOC_OPTIONS=debug=0x34f47d83,inter=100,log=logfile
|
|
The 'debug=' value is generated using the following command
|
|
dmalloc -p log-stats -p log-non-free -p log-bad-space \
|
|
-p log-elapsed-time -p check-fence -p check-heap \
|
|
-p check-lists -p check-blank -p check-funcs -p realloc-copy \

-p allow-free-null

|
Electric-fence support:
|
|
-----------------------
|
|
This enables compiling with Electric-fence support. Electric
|
|
fence is another very useful malloc debugging library which uses
|
|
your computer's virtual memory hardware to detect illegal memory
|
|
accesses. This support will make busybox be considerably larger
|
|
and run slower, so you should leave this option disabled unless
|
|
you are hunting a hard to find memory problem.
