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.
