Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Binary file used to test this behavior of tftp
Description of problem:
TFTP transfer between the server running tftp-5.2-22 and the client running tftp-5.2.11 changes the file.
Version-Release number of selected component (if applicable):
tftp-5.2-11.el7.x86_64
How reproducible:
On Server Side : tftp-5.2-22.el7.x86_64 : RHEL 7.5
# md5sum last
8e0ac1058ab6cb3876ecaa727b2313fd last
# ls -l last
-rwxr-xr-x. 1 root root 19568 Jan 27 2014 last
Client Side : tftp-5.2-11.el7.x86_64 : RHEL 7.1
# md5sum last
2398146098365baa85e8682b36037ceb last
# ls -l last
-rw-r--r--. 1 root root 19555 Jun 30 07:42 last
Then updated it to tftp-5.2-22.el7.x86_64, and now checksum and size are same as that were on Server side
# md5sum last
8e0ac1058ab6cb3876ecaa727b2313fd last
# ls -l last
-rw-r--r--. 1 root root 19568 Jun 30 07:48 last
Steps to Reproduce:
1. Install tftp-5.2-22.el7.x86_64 on server
2. Install tftp-5.2-11.el7.x86_64 on client side
3. Now transfer the file using tftp
$> tftp <server-ip>
tftp> get last
File gets transferred but file size and checksum does not match
Actual results:
File checksum and size changed
# md5sum last
2398146098365baa85e8682b36037ceb last
# ls -l last
-rw-r--r--. 1 root root 19555 Jun 30 07:42 last
Expected results:
File checksum and file size should not change at all, it should be as it.
Additional info:
Actual size and checksum of the file on server side is :
# md5sum last
8e0ac1058ab6cb3876ecaa727b2313fd last
# ls -l last
-rwxr-xr-x. 1 root root 19568 Jan 27 2014 last
When using tftp-5.2-22.el7.x86_64 on client instead of tftp-5.2-11.el7.x86_64, files are getting transferred as expected. Without any changes.
Red Hat Enterprise Linux 7 shipped it's final minor release on September 29th, 2020. 7.9 was the last minor releases scheduled for RHEL 7.
