Hello everyone, Recently Nathan March reported on centos-virt list he's getting frequent Linux kernel crashes with Linux 4.9 LTS kernel because of the missing patch "tty: Fix ldisc crash on reopened tty". The patch was already merged upstream here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=71472fa9c52b1da27663c275d416d8654b905f05 but then

Just in case anyone else on this list is running into similar issues, I can confirm that the patch appears to have resolved this. I've opened https://bugs.centos.org/view.php?id=13713 It was so bad that having the system under load (with rpmbuild) and opening another ssh window or two would almost always cause the oops.

Firstly, I''m still learning Ruby and rails, so there could be a very simple solution to this. I want to search across multiple tables with a "like" query eg: (SQL is probably the easiest way to describe it): select products.* from products inner join brands on products.brand_id = brands.id where products.name like ''%canon%'' or brands.name like

Hi Recently I upgraded my kernel to 2.6.11 (debian) and applied some patches from pom-ng (netfilter) and the iproute2-ss050330 package I have been experiencing a lot of crashes in the kernel (snip below) ================================== Apr 5 20:00:21 sydlxfw01 kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000221 Apr 5 20:00:21 sydlxfw01 kernel: printing eip:

Unlink files, symlinks, FIFOs, devices etc. (except directories) before writing them when extracting CPIOs. This stops weird behaviour like: 1) writing through symlinks created in earlier CPIOs. eg foo->bar in the first CPIO. Having foo as a non-link in a subsequent CPIO, results in bar being written and foo remaining as a symlink. 2) if the first version of file foo is larger

I have a model, listings. Listings habtm categories and subcategories, which are seperate models. What I want to do is search categories for certain items, like so: @categories = Category.find(:all, :conditions => ["name LIKE ?", "#%{:search_string}%" and subcategories for the same: @subcategories = Subcategory.find(:all, :conditions => ["name LIKE ?",

The following patch unlinks (deletes) files, symlinks, FIFOs, devices etc before writing them when extracting CPIOs. It doesn't delete directories. This stops weird behaviour like: 1) writing through symlinks created in earlier CPIOs. eg foo->bar in the first CPIO. Having foo as a non link in a subsequent CPIO, results in bar being written and foo remaining as a symlink. 2)

I have a search form; I grab the value and use it in a fulltext query: :conditions => ["idxfti @@ ''" + search_string + "''::tsquery and ...........] Characters in search_string like "?", ":", bomb active record. I tried a single tick and "\" to escape those, but active record still bombs (same queries via psql work). Suggestions?

Hello everyone, Some of you might remember discussions earlier in 2017 (huh, long time ago) on centos-virt list about Linux kernel tty/ldisc related bug, which caused Xen dom0 kernel crashes for some people (and also more easy to trigger crashes on other arches, like on hp pa-risc), but the bug was difficult to reproduce for others/most people. Fix for this issue was merged to centos virt-sig

I'd forgotten about that despite being the one who ran into it. Looks like that patch was just removed in 4.9.75-30 which I just upgraded this system to:

Hello, I built 4.9.155 for both el6 and el7, you can test them here: https://repo.aerisnetwork.com/archive/kernel-4.9.155-34.el6.x86_64.rpm https://repo.aerisnetwork.com/archive/kernel-4.9.155-34.el7.x86_64.rpm It works fine for me so far on el6, I'll update my pull request later on GitHub with this version. [root at node-tmp1 ~]# cat /proc/version Linux version 4.9.155-34.el6.x86_64
