Message-ID: <20121118110523.GA12094@shrek.podlesie.net> Date: Sun, 18 Nov 2012 12:05:23 +0100 From: Krzysztof Mazur <krzysiek@...lesie.net> To: gregkh@...uxfoundation.org, moinejf@...e.fr Cc: linux-kernel@...r.kernel.org, alan@...ux.intel.com Subject: vt: regression caused by "Fix line garbage in virtual.." Hi, commit 81732c3b2fede049a692e58a7ceabb6d18ffb18c (tty vt: Fix line garbage in virtual console on command line edition) introduced some regression in deleting characters/clearing line during selecting previous command in bash by using "up" arrow. The problem can be reproduced by two following commands: echo -n "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" echo -e "\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x08\x1b\x5b\x33\x50\x64\x72\x69\x76\x65\x72\x73\x2f\x69\x6e\x70\x75\x74\x2f\x6d\x6f\x75\x73\x65\x64\x65\x76\x2e\x63" (the first command generates just some garbage, the second command generates string captured by strace when the issue occured). On Linux v3.6 the resulting line is: ...AAAdrivers/input/mousedev.c with fbcon on inteldrmfb and v3.7-rc6 ...AAAdrivers/input/mousedev.c A with fbcon on radeondrmfb and v3.7-rc6 ...AAAdrivers/input/mousedev.cAAA There are some garbage after mousedev.c not present on older kernels. Reverting commit 81732c in v3.7-rc6 fixes the issue.
