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.

Description Vaios Papadimitriou 2010-11-29 19:41:58 UTC 
This is a request to add to the RHEL6.1 kernel the following patches already submitted in the upstream kernel:

1.
http://git.kernel.org/?p=linux/kernel/git/jejb/scsi-rc-fixes-2.6.git;a=commit;h=78d16341facf829a71b6f7c68ec5511b9c168060

[SCSI] scsi_transport_fc: fix blocked bsg request when fc object deleted.

This patch is already merged into 2.6.37-rc1 kernel.

2. 
http://marc.info/?l=linux-scsi&m=128975117904385&w=2

bsg: correct fault if queue object removed while dev_t open

This patch has not been committed to a git pool yet. However, this patch is *assumed* to be accepted as there was no negative comments/concerns since its submission on 11/14/2010.


The above kernel patches address issues found while testing with the Emulex LPFC device driver.

Your commit:

    [SCSI] bsg: correct fault if queue object removed while dev_t open
    
    This patch corrects an issue in bsg that results in a general protection
    fault if an LLD is removed while an application is using an open file
    handle to a bsg device, and the application issues an ioctl. The fault
    occurs because the class_dev is NULL, having been cleared in
    bsg_unregister_queue() when the driver was removed.  With this
    patch, a check is made for the class_dev, and the application
    will receive ENXIO if the related object is gone.
