I use a more recent busybox version than my built-in version in recovery mode.
I copied the appropriate busybox binary to my device (architecture: arm) and call the ls command from it and get cryptic file names.
can someone tell me what this comes from? compared to the screenshot with the built-in ls

umount.c is (afaics) missing a quiet flag.
It would be nice with option symmetry to quiet down messages instead of sending it to the void.

I build busybox for aarch64 by gcc-linaro-7.5.0, and I found that when I make with the defult "Use internal resolver code instead of libc" , it report errors as log shows; if I cancel it, it works very well.

error logs:

Hi.
When I run busybox wget https://ftp.openbsd.org/pub/OpenBSD/LibreSSL/libressl-2.6.4.tar.gz, I'm getting:

Connecting to ftp.openbsd.org (129.128.5.191:443)
wget: TLS error from peer (alert code 40): handshake failure
wget: error getting response: Connection reset by peer

This issue occurs only with https. BusyBox v1.27.2 on Alpine Linux.
Thank you.

Hi,

busybox ls only shows the first eight characters of a username and a group. Is there any reason against showing the complete username or group?

Cheers,
Marco

I use busybox with buildroot, after linux starts, only eth0 can get ip through dhcp. eth1 cannot obtain IP automatically. I need to execute udhcpc -i eth1, then eth1 to obtain IP.

Can anyone give me some advice to automatically get the IPs of all network cards after linux boots。
Thanks!

Typo twice in ping.c

I've seen this strange issue while working with busybox v1.29.3 in Rancher k8s cluster v1.23.13+rke2r1. It's unable to do nslookup

shivesh@shivesh-machine:~/rancher$ kubectl run -i --tty --rm debug --image=busybox:1.29.3  --restart=Never -- sh

If you don't see a command prompt, try pressing enter.

/ # nslookup github.com
Server:		10.43.0.10
Address:	10.43.0.10:53

Non-authoritative answer:

*** Can't find github.com: No answer

But when I'm trying to do the same from pod with the latest busybox image, it worked flawlessly.

shivesh@shivesh-machine:~/rancher$ kubectl run -i --tty --rm debug --image=busybox  --restart=Never -- sh
If you don't see a command prompt, try pressing enter.

Hi,
I just started using bussybox 1.30 verion, i am able to run udhcpc6 and get v6 ip, but my requirement is to get options
0X5F -MAPT
0X38 -NPT-Server
0X18 -Optional domain list
0X17-DNS-Servers
0X11 -Vendor-options
Right now i am able to get only DNS information, Can any one guide how to can i send custom options request in udhcpc6 client request??

default.script:
echo "Args **** $0 , $1 "
echo " Time-zone $timeZone"
echo " Time-servers $timeserver "
echo " Ntp-servers $ntpsrv "
echo " DNS-server $dns "

Result:
Args **** /usr/share/udhcpc/default.script , bound
Time-zone
Time-servers
Ntp-servers
DNS-server 2606:4700:4700:0000:0000:0000:0000:1111 2001:4860:4860:0000:0000:0000:0000:8888 2001:4860:4860:0000:0000:0000:0000:8844

Any information on this is greatly appreciated.
Thanks,

I have noticed the version of grep in busybox is relatively aged/limited. Is it possible to have this updated to something more recent that perhaps supports -P ?
Thanks

Hi,

I am currently working on RISC-V based processor for which we are now moving from BBL (loaded through GDB) to standalone boot-up using OpenSBI and U-Boot. We have written the UART Driver and SPI Driver in U-Boot and can now load/boot linux (vmlinux - BIN) but I can see that the busybox throws a "Segmentation Fault" after I login into the system. The "sh" in busybox is the one throwing segmentation fault here. I have attached the bootup log.

OpenSBI v0.9

Why won't busybox include full gnu programs instead of their own ones?

Refer https://vulncat.fortify.com/en/detail?id=desc.internal.cpp.buffer_overflow_off_by_one

Code Snippet:

line[0] = '\n';

I don't know much about what fixdep is doing, but I think that stands for "fix dependencies," right? It doesn't seem to have that missing file error when compiling with gcc, so either it doesn't usually run that or the file is there

Can you please embed wifi-tools and especially wpa_supplicant that uses the internal SSL library. wifi-tools are easy to build but wpa_supplicant is a nightmare. It will be nice to have them out of the box.

I'm using the following sendmail version:

/magento # sendmail --help
BusyBox v1.34.1 (2022-07-19 20:11:24 UTC) multi-call binary.

The issue happens with PHP8. Its mail function sends headers and body with \r\n line delimiters according to standards and passes this data to sendmail. But sendmail converts all line-endings to \r\r\n making the whole mail broken.

got this error while crosscompile
make O=../output/busybox/ -C $PWD/busybox/ ARCH=arm CROSS_COMPILE=arm-9tdmi-linux-gnueabi-
how to solve this

We have been using busybox 1.31.0 in the past, but recently upgraded to version 1.34.1 to fix vulnerabilities in AWK and Hush.
Accidentally,CTRL+C will exit the current shell terminal directly, which was not the case in 1.31.0.
And notice that on the master branch, there's a commit ' ash: ^C with SIG_INGed SIGINT should not exit the shell '
May I apply this patch to fix the problem which I mentioned?
Thanks.

Apparently, when using length() function to get a passed array's length, busybox will return a wrong value.

RIGHT:
$ gawk 'function f(arr) { print length(arr) } BEGIN { arr[1]=0; arr[2]=0; f(arr) }'
2

WRONG:
$ awk 'function f(arr) { print length(arr) } BEGIN { arr[1]=0; arr[2]=0; f(arr) }'
0

Fortunately, passing a string works just fine though.

RIGHT:
$ gawk 'function f(str) { print length(str) } BEGIN {str="abcd"; f(str) }'
4

RIGHT:
$ awk 'function f(str) { print length(str) } BEGIN {str="abcd"; f(str) }'
4

Unfortunately, busybox awk is still return number of bytes instead of characters.

RIGHT:
$ echo 絵 | gawk '{print length}'
1

WRONG:
$ echo 絵 | awk '{print length}'
3

When I run and pull the latest image or 1.34.1 of busybox on the arm64 device.
I execute the following command and it returns exit code 139

[root@master-001 ~]# docker run -it  busybox:1.34.1
[root@master-001 ~]# echo $?
139

[root@master-001 ~]# docker run -it  busybox:1.33.1
/ # 

When I changed to 1.33.1, this worked fine, I tried docker export, and executed /bin/sh, and a segment fault was reported.

[root@master-001 ~]# ~/busy/bin/sh
Segmentation fault

I know that you're looking for compatibility, but this command once removed a directory with files very important to me. Can you please consider changing this to #if 1?

[busybox 1.33.0, aarch64, entware.net build]

Download reliably stalls right before finish when used behind a separate firewall box that forwards traffic through openvpn (this is my case, might be the same with different routing technologies as well). Escaping and invoking a new download with '-c' can finish download as intended. Curl and non-busybox wget work without stalling, busybox wget works as well if traffic is not routed through openvpn. (It feels like busybox wget does not get or handle the end of transfer signal correctly?)

Sorry, I am not yet familiar with the project, should i report this in email as well as per the contirbuting guidelines? (Or should I have done just that instead of doing it here?)

If an error occurs opening /dev/null on the second line, it will be written to stderr, but the first line just moved stderr to fd 3, so no message will appear.

because curl is so popular, please contain this command in the busyboxy image. THX!

In current form, when there is a file with two consecutive spaces in it's name and the hashlist contains binary mode markers " *" validation fails.
Both markers should be searched and in case both are not NULL lower index should be selected, or instead using strstr precomputed marker positions based on hash width should be used.

It would be really great if nslookup supoorted the SRV query type.

This will be especially useful for openwrt and specifically freifunk-berlin.

ctrl+c is closing the telnent connection in 1.31.0
It was working in busybox 1.19.0

sha256sum: unrecognized option '--quiet'
BusyBox v1.31.0 (2019-09-21 22:43:03 IST) multi-call binary.

Usage: sha256sum [-c[sw]] [FILE]...

Print or check SHA256 checksums

    -c      Check sums against list in FILEs
    -s      Don't output anything, status code shows success
    -w      Warn about improperly formatted checksum lines

Would it be possible to add support for:

busybox --version

The reason i am asking is because I tend to batch-query installed/available versions, and also having busybox available (as a statically compiled variant for rescue-purposes mostly), so this feature wuold be quite useful to me. Thanks for reading!

Can you add https for Mailing Lists?

• http://lists.busybox.net/mailman/listinfo

-> https://lists.busybox.net/mailman/listinfo

And of course redirect all http:// links to https://.

Thanks in advance.

Doing the following:

cd /tmp
cp /bin/ls .
cp ls ls2
vi ls2 # Change some bytes and delete some bytes
busybox diff -au ls ls2 > ls.patch
busybox patch ls > ls.patch

Hunk 1 FAILED 7/7.

This does not happen on normal linux patch.

Hello,

I checked ping6 command from latest version of busybox(1.35.0).

root@-virtual-machine:/home/# ./busybox_PING6
Usage: ping6 [OPTIONS] HOST

Send ICMP ECHO_REQUESTs to HOST

-c CNT		Send only CNT pings
-s SIZE		Send SIZE data bytes in packets (default 56)
-i SECS		Interval
-A		Ping as soon as reply is recevied
-I IFACE/IP	Source interface or IP address
-W SEC		Seconds to wait for the first response (default 10)
		(after all -c CNT packets are sent)
-w SEC		Seconds until ping exits (default:infinite)
		(can exit earlier with -c CNT)
-q		Quiet, only display output at start/finish
-p HEXBYTE	Payload pattern

It does not show -t. option, but when i give -t option , it is not throwing error also. And echo request is sent with TTL of 64.
root@virtual-machine:/home# ./busybox_PING6 3001::22 -t 100
PING 3001::22 (3001::22): 56 data bytes
64 bytes from 3001::22: seq=0 ttl=64 time=0.062 ms
64 bytes from 3001::22: seq=1 ttl=64 time=0.093 ms
64 bytes from 3001::22: seq=2 ttl=64 time=0.079 ms
^C

Busybox ping6 really supports "TTL" option ?? if so ..is there a way to enable that ??

Thanks,
Nag

The following script

cat << EOF | sort -k2rn -s
a 1
b 2
c 1
d 2
EOF

returns should return the lines a, b, c, d according to the documented behavior of the 'stable' (-s) parameter, but instead returns d, b, c, a. It should reverse the order of the second column only and keep the first in the same order provided via stdin according to the -r flag as the implementation from GNU coreutils does. Is this a bug or did I misunderstand how stable sorting is supposed to work?

Both Busybox 1.34.1 and 1.35.0 are affected by Critical CVE https://nvd.nist.gov/vuln/detail/cve-2022-28391

Can you please provide any update on when is this going to be fixed with the expected version number.

Thank you

There are missing releases/tags:

• https://github.com/mirror/busybox/releases

Invoking iostat without parameters produces, e.g. this:

...
sda              16.35      1864.52       224.26  100203215   12052400
sdb               0.04         3.60         0.00     193736         32
sdb1              0.04         3.59         0.00     192696         32
dm-0              7.85       360.11       128.75   19352880    6919456
...

And although my sda1-sda6 partitions aren't displayed, sdb1 still is.

procps/iostat.c reads:

/*
 * Is input partition of format [sdaN]?
 */
static int is_partition(const char *dev)
{
	/* Ok, this is naive... */
	return ((dev[0] - 's') | (dev[1] - 'd') | (dev[2] - 'a')) == 0 && isdigit(dev[3]);
}

If the intention was to exclude all partitions (not only sdaN), shouldn't it be something like:

return ((dev[0] - 's') | (dev[1] - 'd') | (dev[2] - 'a')) >= 0 && isdigit(dev[3]);

[EDIT] or rather:
return ((dev[0] - 's') | (dev[1] - 'd')) == 0 && (dev[2] - 'a' >= 0) && isdigit(dev[3]);

?

Then it results in:

...
sda              16.37      1866.92       224.56  100199631   12052400
sdb               0.04         3.61         0.00     193736         32
dm-0              7.86       360.58       128.92   19352880    6919456

Makefile:743: recipe for target 'networking/udhcp' failed

We are using Chef Habitat to install several RPM packages (DataDog 'Agent' is currently the big one we are trying to deploy) on Linux AWS EC2 instances and have noticed in the chef-stacktrace.out error file that references BusyBox. We are trying to narrow down where the problem is located - is it a BusyBox, Chef Habitat, Chef Server or Chef Infra client issue?

Hi,
I just started using bussybox 1.30 verion, i am able to run udhcpc6 and get v6 ip, but my requirement is to get options
0X5F -MAPT
0X38 -NPT-Server
0X18 -Optional domain list
0X17-DNS-Servers
0X11 -Vendor-options
Right now i am able to get only DNS information, Can any one guide how to can i send custom options request in udhcpc6 client request??

default.script:
echo "Args **** $0 , $1 "
echo " Time-zone $timeZone"
echo " Time-servers $timeserver "
echo " Ntp-servers $ntpsrv "
echo " DNS-server $dns "

Result:
Args **** /usr/share/udhcpc/default.script , bound
Time-zone
Time-servers
Ntp-servers
DNS-server 2606:4700:4700:0000:0000:0000:0000:1111 2001:4860:4860:0000:0000:0000:0000:8888 2001:4860:4860:0000:0000:0000:0000:8844
Bound

Any information on this is greatly appreciated.
Thanks,

As this is inside of the function log5, should this 4 be a 5?

Background:

• Using busybox as init containers with commands as below, the wget failed.
  args:
  wget -O /agent-dir/agent.zip https://infc.oss-cn-haal..com/agent/adm****ent/agent-2.7.0.zip

errorlog ex:

wget https://www.baidu.com

Connecting to www.baidu.com (180.97.34.96:443)
wget: note: TLS certificate validation not implemented
wget: error getting response: Connection reset by peer

Env:

• busybox image version ：latest (2023.1.10 1.36.0)
  wget -v
  wget: invalid option -- 'v'
  BusyBox v1.36.0 (2023-01-03 22:42:57 UTC) multi-call binary.

Issue :

• in the scenario of https communitation, the wget client sends "finack" and closes the connection before a "server hello" arrives. Refer to the tcpdump traces
  as below
  

Workaround:

• Replace image version to 1.34.0, it works
