patch to adjust socket buffer accounting.
This patch corrects this issue by moving socket layer accounting to the top
level skbuff. By doing this all SNDBUF memory is released on the freeing of
the top level skbuff, which allows individual fragments to be cloned without
affecting the accounting. I also checked, and this problem seems to present in
the 2.6 kernel as well, so this patch should probably be pushed there.
A fix for this problem has just been committed to the RHEL3 U4 patch pool this evening (in kernel version 2.4.21-20.1.EL). An errata has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2004-550.html |
