Created attachment 477052 [details] a code required to get gzdirect() into zlib Description of problem: There is a bug in libxml2 library (BZ #675172), which can be fixed only in case zlib would contain gzdirect() function (see BZ #675172 comment #2 for more info). gzdirect() function is included in upstream version 1.2.2.3, but RHEL4 contains 1.2.1.2. Version-Release number of selected component (if applicable): zlib-1.2.1.2-1.2 How reproducible: N/A Steps to Reproduce: N/A Actual results: BZ #675172 cannot be fixed due to missing gzdirect() function Expected results: gzdirect() in zlib Additional info: a patch to show the required changes attached
This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux.
Only important issues like performance and security are fixed in RHEL 4.9 and later. This bug does not meet necessary criteria and is therefore closed.
Hello, I was working with Martin in case SFDC#00394024 investigating the segmentation fault issue in up2date. Due the excellent Martin analysis, we could verify that the issue occurs exactly at strncmp() function. 2194 if (gzread(context, buff4, 4) == 4) { 2195 if (strncmp(buff4, cptr, 4) == 0) 2196 ret->compressed = 0; 2197 else 2198 ret->compressed = 1; Due the work made in other BZ#664060[1], we back-ported the upstream patches to RHEL4 packages. We sent the back-ported packages to a customer and customer said that packages worked as excepted. Below, the customer note: "Hello, I have a good news :) With the update of the libxml2, libxml2-python, zlib-devel, zlib packages Now it works. I registered the client to the redhat network! You can close this call. Thank you for your help. Best regards Yvan" Those RHEL4 packages are available at http://people.redhat.com/mdemello/fixes/SFDC00394024. The internal CVS branches are: libxml2-2_6_16-12_8_TEST_SFDC00394024 zlib-1_2_1_2-1_2_TEST_SFDC00394024 Related BZs: * https://bugzilla.redhat.com/show_bug.cgi?id=675207 * https://bugzilla.redhat.com/show_bug.cgi?id=664060 Since the issue is clearly, we would like to request an official back-port for zlib and libxml2 packages for RHEL4. Thank you. Cheers, Marcelo Moreira de Mello [1] - https://bugzilla.redhat.com/show_bug.cgi?id=664060
*** BZ were re-opened ****
Patch looks ok (higher version of zlib 1.2.5 - have a feature which enable the function to return the state->direct in more situation, but the present version seems which is already tested by the customer is sufficent).
