[Bug libc/176] New: Process accounting do not handle uids > 64k

[pere at hungry dot com]

I found this in the mailing list archive for bug-glibc.  Checking
glibc CVS, the types in <sys/acct.h> is still u_int16_t and unable
to store uids above 64k.  The types should be changed to 32-bit.

Greetings:

Not sure who to address this to, but I'd like to see if it would be possible
to get a patch submitted to change to field types in the BSD process account
struct in sys/acct.h.  The problem lies in that both your file and the one
shipped with the Linux kernel do not allow proper accounting for high
UID/GIDs, a feature that's enabled by default on most platforms.  I'd like to
get your struct to define ac_uid and ac_gid to uid_t and gid_t, respectively,
which should always accurately reflect what the kernel is using, itself.

I am currently trying to get the same changes accepted in the kernel source.

As it stands, high uid/gid accounting is broken in both the current Linux
kernel branch and your includes.  Since most accounting tools use sys/acct.h
in preference to linux/acct.h, fixing only one will not fix the problem.

If such a change is possible, or if I need to pursue this through other
channels, I'd greatly appreciate your feedback.  Thank you.

This data structure is not used by libc, just exported in the <sys/attr.h> header.
The format is dictated by the Linux kernel, and you will have to get it changed
first.  When it changes, we can update libc's definition of the struct to match.

There is now an effort going on to improve the kernel accounting
implementation.  See <URL: http://www.kerneltraffic.org/kernel-traffic/latest.html#18 >
and <URL: http://elsa.sourceforge.net/ > for more info.

This is no glibc issue.  Work with the kernel people.
