Busybox - Invalid argument since r31533 Broadcom K2.6

[doktornotor]

Dead simple things like

echo foo > /tmp/bar

fail with

-sh: 1: Invalid argument

Breaks startup scripts and tons of other things. Also reported here: ​http://www.dd-wrt.com/phpBB2/viewtopic.php?p=1070010#1070010

Still broken on E4200 with dd-wrt.v24-31722_NEWD-2_K2.6_mega-nv60k.bin

Anyone alive here? Kinda high priority breakage if you ask me.

This project sucks big time. You could as well close the bug tracker, completely useless. Switching to LEDE.

I confirm this is still the case for a E2000 as of r33679 (k2.6), which is a major problem since that a lot of things do not work correctly (eg. wifi scheduling or anything needing to write into files).

It works however using K3X firmwares, but my router just crawls under the extra load (transfer speeds are 10x slower), so that's not an option.

I tried to search for the bug in the commits, but the changeset [31277:31533] is quite daunting...

[RuiPereira]

As a side note, a similar bug was reported ​upstream, but it seems to be a problem with the busybox config or compilation in dd-wrt.

Still an issue as of R33679 (E4200/dd-wrt.v24-33679_NEWD-2_K2.6_big-nv60k).

This is kind of critical since more recent builds are required for the krack vulnerability fix.

Only workaround I've found is to change the following: echo foo > /tmp/bar TO echo foo | tee /tmp/bar echo foo >> /tmp/bar TO echo foo | tee -a /tmp/bar

[doktornotor]

And still an issue with r36808, in fact, it got MUCH worse, see ​https://svn.dd-wrt.com/ticket/6373

Bad joke, really.

[kernel-panic69]

Tested up to r37406 (r37405, K2.6 builds seem to be one off in version number), still an issue in K2.6 builds.

Also to note, the webUI command shell also has issues, which could be related somehow: ​https://svn.dd-wrt.com/ticket/4121

[kernel-panic69]

Tested all the way up to r37582 and still broken.

[doktornotor]

2 years later, still the same shit. Impressive.

[darxis]

It has been 2 years that the following things are broken because of this bug:

• OpenVPN not working
• running scripts from USB not working
• running commands from WebUI Command form not working
• startup scripts not working
• telnet working but disconnects when executing stuff like 'echo xxx > /tmp/tmp.tmp'

Will it be fixed in the nearest future?

Edit: still broken as 37305

[doktornotor]

Replying to darxis:

Will it be fixed in the nearest future?

Sure thing, planned right after human landing on Mars.

[kernel-panic69]

#4121 closed due to it being a matter of command input. #6373 is still an active ticket. I haven't tested K2.6 builds in a while to see if this has been fixed.

[kernel-panic69]

Still a problem on k2.6 builds @ r40634 mega on E4200v1

Finally, some progress:

​https://svn.dd-wrt.com/changeset/40707

​https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=1173893#1173893

Should be able to close this ticket soon enough, if the commit fixes these issues.

[kernel-panic69]

Tested in alpha builds 40708 and 40711, looks like it's good to go! ​https://svn.dd-wrt.com/ticket/6373#comment:37
