  • 31 March 2017 -- Note for users of Linux kernels older than 2.6.27

    If you are stuck with a kernel from July 2008 or earlier (2.6.26 or less), and you are using mdev, device scan wouldn't work correctly due to an incompatibility in /sys structure. You can work around it by reverting this patch in 1.26.x BusyBox sources. (You also probably need to plan migration to a less ancient kernel).

  • 10 January 2017 -- BusyBox 1.26.2 (stable)

    BusyBox 1.26.2. (git, patches, how to add a patch)

    Bug fix release. 1.26.2 has fixes for ash (redirect fds sometimes were not closed), module utilities and tcpsvd (build fixes), build system (IFUPDOWN_UDHCPC_CMD_OPTIONS option was not settable).

  • 2 January 2017 -- BusyBox 1.26.1 (stable)

    BusyBox 1.26.1. (git, patches, how to add a patch)

    Bug fix release. 1.26.1 has fixes for single-applet builds (all applets are verified to successfully build when individually selected), a few tweaks to defconfig were made.

    Static binaries are available for downloads, with each individual applet enabled separately, as well as the binary with almost all applets selected, and helper binaries (ssl_helper for HTTPS wget support, index.cgi, post_upload.cgi and httpd_ssi for HTTP server).

  • 25 March 2016 -- Building on an Android tablet.

    Android is based on Linux kernel, but sadly and unexplicably, Android userspace is not Unix-friendly: in many cases, things are done differently than in "usual" Unix systems. For example, there is no /bin directory (and therefore ubiquitous #!/bin/sh scripts won't work). Instead, there is /system/bin.

    I have a Samsung Galaxy Tab S (SM-T700 model) and I made it compile Busybox as follows:

    • "Rooted" the tablet (acquired root access). This step is device-specific.
    • Installed the SuperSU application.
    • Installed the Termux application - it provides a small repository of essential tools: gcc-based toolchain, git, ncurses, etc.
    • Ran its terminal, installed packages I needed, pulled Busybox git tree.
    • Created a /bin symlink to /system/bin, to make #!/bin/sh scripts work (the build fails otherwise).
    • Now the usual "make defconfig", "make menuconfig", "make" work.

    Some parts won't compile (not all kernel headers are present, libc API different or incomplete, etc). The maximal config which did compile is now in the git tree, in configs/android_502_defconfig. The toolchain provided by Termux is based on Android's Bionic libc and Bionic has some design problems. An annoying one is that off_t is 32-bit, struct_stat::st_size is not off_t (this violates standard expectations), therefore CONFIG_LFS=y does not build, and CONFIG_LFS=n builds with warnings (printf'ing st->st_size with wrong specifier).

  • 24 March 2016 -- BusyBox 1.24.2 (stable)

    BusyBox 1.24.2. (git, patches, how to add a patch)

    Bug fix release. 1.24.2 has fixes for build system (static build with glibc fixed), truncate, gunzip and unzip.

  • 24 October 2015 -- BusyBox 1.24.1 (stable)

    BusyBox 1.24.1. (git, patches, how to add a patch)

    Bug fix release. 1.24.1 has fixes for ftpd (DIR parameter works for non-root too), httpd (heap overflow fix), sort (fix for a a problem affecting glibc build). Build system has a fix for the lost link-time optimizations. In 1.24.0 announcement, you might have noticed that sizes unexpectedly grew relative to 1.23.2. Now it is fixed:

       text    data     bss     dec     hex filename
     860126     486    7272  867884   d3e2c busybox-1.23.2
     869074     516    7364  876954   d619a busybox-1.24.0 (buggy link script)
     858906     486    7180  866572   d390c busybox-1.24.0 (fixed link script)
     858941     486    7180  866607   d392f busybox-1.24.1

    Check out a new applet, "uevent". It is a netlink listener. It provides alternative to having mdev as kernel hotplug helper. Instead of setting up the former via "echo /sbin/mdev >/proc/sys/kernel/hotplug", start "uevent mdev" early during boot. "uevent" will run "mdev" for each hotplug event, waiting for each child to terminate before starting a next one.

    The former method does not require a long-lived listener process, but it is racy: many copies of mdev can run in parallel.

  • 12 October 2015 -- BusyBox 1.24.0 (unstable)

    BusyBox 1.24.0. (git, patches, how to add a patch)

    Sizes of busybox-1.23.2 and busybox-1.24.0 (with equivalent config, static uclibc build):

       text    data     bss     dec     hex filename
     860126     486    7272  867884   d3e2c busybox-1.23.2

    I would like to feature some less-known useful tools in Busybox. Let me talk about "nmeter" applet. I find myself using it surprisingly often. For example, it helped me to correctly parallelize a very large multiple kernel build job (~30000 kernel builds) so that all CPUs are loaded, but machine isn't evicting file cache because it has too many jobs for installed RAM.

    When dealing with a machine which seems to be sluggish, it takes some time to pinpoint the cause. It can be lack of free memory. It can be excessive CPU load. It can be misbehaving (slow) storage or network. nmeter allows to monitor many such parameters and presents them in a compact one-line form. This lets you see the time evolution as well. Here is an example:

    # nmeter '%t %c x %x m %[mf] f%p p %[pn] b %b net%[neth0]'
    20:51:22 .......... x  837 m 2.2g f   0 p  377 b    0    0 net    0    0
    20:51:23 .......... x 1195 m 2.2g f   0 p  377 b    0    0 net  128    0
    20:51:24 .......... x 1687 m 2.2g f   0 p  377 b    0    0 net   64    0
    20:51:25 .......... x 1829 m 2.2g f   0 p  377 b    0    0 net  875   70
    20:51:26 U......... x 1567 m 2.2g f   6 p  377 b    0    0 net   64    0
    20:51:27 U......... x 1451 m 2.2g f   0 p  377 b    0    0 net   64    0
    20:51:28 .......... x 1332 m 2.2g f   0 p  377 b    0    0 net   64    0
    20:51:29 .......... x 1698 m 2.2g f   0 p  377 b    0    0 net   64    0
    20:51:30 .......... x 1640 m 2.2g f   0 p  377 b    0    0 net   64    0
    20:51:31 .......... x 1397 m 2.2g f   0 p  377 b    0    0 net   64    0
    20:51:32 .......... x 1244 m 2.2g f   0 p  377 b    0 4096 net   64    0
    20:51:33 U......... x 1660 m 2.2g f   0 p  377 b    0    0 net  128    0
    20:51:34 U......... x 1793 m 2.2g f   0 p  377 b    0    0 net   64    0
    20:51:35 .......... x 1583 m 2.2g f   0 p  377 b    0    0 net   64    0
    20:51:36 .......... x 1308 m 2.2g f   0 p  377 b    0    0 net   64    0

    If CPU load is high, the CPU bar will immediately show this. %x column shows context switches per second, allowing to detect cases where processes are waking and waiting on each other excessively. %[mf] is free memory, and it is smart enough to show actual usable memory: unlike many other tools, it considers buffer cache as free memory. %p and %[pn] columns show forks and number of processes, they let you detect a case where a daemon is respawning continuously. Two %b numbers are block IO read and write rates. %[neth0] is network IO rate on the specified interface. More specifiers exist - please read "nmeter --help" output.

    With -d MSEC option and small values of MSEC, this tool allows to see a detailed view of bursty activity. Sometimes you can literally see every network packet arriving. To make this possible, this tool is written so that it reads the minimum of informaion it needs from /proc. In this example, we can see how a packet arrived to eth0, complete with its IRQ#30 firing:

    # nmeter -d10 '%4t irq%30i net%[neth0]'
    21:07:58.2301 irq   0 net    0    0
    21:07:58.2401 irq   0 net    0    0
    21:07:58.2502 irq   0 net    0    0
    21:07:58.2601 irq   1 net   64    0
    21:07:58.2701 irq   0 net    0    0
    21:07:58.2802 irq   0 net    0    0
    21:07:58.2902 irq   0 net    0    0

    As you see, each update takes about 0.2 millisecond of processing time. You can run even -d1, if you want. -d0 also works, it is a mode where updates are continuous.

    On the other hand, with large update interval, you can run this tool continuously on a server machine and save its output, to be able to investigate mysterious drops in performance at a time when there was no operator present. If you have an oopsing server, it is useful to have another nmeter instance's output to be constantly printed to its console, if you want to see what was going on just before oops. "Is my server occasionally dies in an IRQ storm?" situation.
