[Rafael J. Wysocki]

This message contains a list of some regressions from 2.6.24, for which there

please let me know.

If you know of any other unresolved regressions from 2.6.24, please let me know
either and I'll add them to the list.  Also, please let me know if any of the
entries below are invalid.

Subject: + driver-core-fix-uevent-action-string-regression.patch added to -mm tree
From: akpm
To: mm-commits
Date: 28/03/08 07:51 PM

The patch titled
     driver core: fix uevent action-string regression
has been added to the -mm tree.  Its filename is
     driver-core-fix-uevent-action-string-regression.patch
...

The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

------------------------------------------------------
Subject: driver core: fix uevent action-string regression
From: Mark Lord <lkml@rtr.ca>

On boot, syslog is flooded with "uevent: unsupported action-string;" messages.
..
Mar 28 14:43:29 shrimp kernel: tty ptyqd: uevent: unsupported
action-string; this will be ignored in a future kernel version
Mar 28 14:43:29 shrimp kernel: tty ptyqe: uevent: unsupported
action-string; this will be ignored in a future kernel version
Mar 28 14:43:29 shrimp kernel: tty ptyqf: uevent: unsupported
action-string; this will be ignored in a future kernel version
Mar 28 14:43:29 shrimp kernel: tty ptyr0: uevent: unsupported
action-string; this will be ignored in a future kernel version


These messages are a regression compared with 2.6.24, which did not flood the
syslog with them.

The actual underlying problem was introduced in 2.6.23, when somebody made the
string parsing no longer accept nul-terminated strings as a valid input to
store_uevent().

Eg.  "add\0" was valid prior to 2.6.23, where the code regressed to require
"add" without the '\0'.

This patch fixes the 2.6.23 / 2.6.24 regressions, by having the code once
again tolerate the trailing '\0', if present.

According to GregKH, this mainly affects older Ubuntu systems, such as the one
I have here that requires this fix.

That's not a regression from 2.6.24

..

2.6.24 does not flood my syslog with those messages.
2.6.25-rc* does.   Looks like a regression.

The original bug was a hidden regression in 2.6.23,
which nobody bothered to identify until now.

Just because some code "gets away with" a regression
for a kernel or two, doesn't mean that regression shouldn't be fixed.

in the kernel, and all of them should be fixed...
