f454f6708a udevadm: test - handling trailing '/' in devpath 
On Wed, Mar 18, 2009 at 16:00, Matthias Schwarzott <zzam@gentoo.org> wrote:
found out how the error occurs:
It is a difference between
A. udevadm test /sys/class/mem/null/
and
B. udevadm test /sys/class/mem/null

Case A was the case that showed the error behaviour. It seems udevadm is
confused by the trailing slash. This behaviour seems to be there since ages.

111e4f81ff replace strncpy() with strlcpy() 
The problem was strncpy() doesn't stop after writing the terminating
NUL; by definition it goes on to zero the entire buffer.

I spy another use of strncpy in udev_device_add_property_from_string(),
which is responsible for another ~1% user cpu time...

b29a5e4ab9 use more appropriate alternatives to malloc() 
Use calloc to request cleared memory instead.
Kernel and libc conspire to make this more efficient.

Also, replace one malloc() + strcpy() with strdup().

659353f5a9 replace strerror() usage with threadsafe "%m" format string 
strerror() is not threadsafe.  It uses a buffer to build messages of the form
"Unknown error 387689".

syslog() provides a %m format which is equivalent to strerror(errno).
As a GNU extension, this is also accepted by printf and friends.
At least in the current implementation, it is correctly threadsafe.
