patch to remove utrace patch for ia64
by Doug Chapman 01 Apr '08

01 Apr '08

As discussed in another thread the utrace support for ia64 is not complete upstream yet. The current utrace patch breaks building on ia64. To allow us to continue progress on ia64 can we apply this patch until these issues are resolved? thanks, - Doug *** kernel.spec.bad 2008-04-01 10:37:22.000000000 -0400 --- kernel.spec 2008-04-01 10:37:40.000000000 -0400 *************** ApplyPatch linux-2.6-compile-fix-gcc-43. *** 987,993 **** --- 987,995 ---- ApplyPatch linux-2.6-hotfixes.patch # Roland's utrace ptrace replacement. + %ifnarch ia64 ApplyPatch linux-2.6-utrace.patch + %endif # enable sysrq-c on all kernels, not only kexec ApplyPatch linux-2.6-sysrq-c.patch

Add SELinux permissive domains to fedora kernels
by Eric Paris 01 Apr '08

01 Apr '08

I know its way late but I'd like to add a new SELinux concept to the F9 kernels. Its going to be a backport of a couple of my changesets headed upstream http://git.kernel.org/?p=linux/kernel/git/jmorris/selinux-2.6.git;a=commitd… http://git.kernel.org/?p=linux/kernel/git/jmorris/selinux-2.6.git;a=commitd… http://git.kernel.org/?p=linux/kernel/git/jmorris/selinux-2.6.git;a=commitd… Only the third patch is truly interesting. A permissive domain is a new concept in which a sysadmin can say that a given domain is free to do anything it wants. Lets say a user seriously customized httpd and they want httpd to just be allowed to run wild while still keeping enforcing for everything else in the system. With the kernel patch I want to commit and the userspace changes dan has already pushed this week they just need a simple policy which says "permissive httpd_t" and all their httpd_t denials become allows! One of the upstream patches adds a BUG_ON() but I'm still a teensy bit scared of it so in the F9 patch I'll probably make it a WARN_ON since it isn't really deadly to the kernel... anyway. Chances of regression here are very very low. I would just jam this in myself but we are getting really late and I wanted people to be able to tell me no before I did it. If noone strongly objects quickly expect to see a commit message early this week.... -Eric

kernel posttrans and preun hooks for other packages
by Matt Domsch 01 Apr '08

01 Apr '08

https://bugzilla.redhat.com/show_bug.cgi?id=433121 DKMS would like to have the opportunity to run it's auto-rebuilder/installer after a new kernel RPM has been installed, without having to wait for a system restart to run it. Likewise, when a kernel RPM is removed, it would like to be able to run to remove modules managed by it. Debian kernels intentionally run scripts located in /etc/kernel/postinst.d/ following new kernel package installation, /etc/kernel/prerm.d/ before kernel package removal. DKMS drops a script into these directories, to perform the appropriate actions. I want Fedora and RHEL kernels to do likewise. Patch attached. This patch implements the same interface as that used for Debian and Ubuntu kernels. The scripts are invoked with $1 = kernel version, and $2 = path to vmlinuz file. (DKMS doesn't need $2, but I'm keeping the interface the same to match so people can reuse their scriptlets.) -- Matt Domsch Linux Technology Strategist, Dell Office of the CTO linux.dell.com & www.dell.com/linux --- kernel.spec.orig 2008-02-15 21:06:33.000000000 -0600 +++ kernel.spec 2008-02-16 00:07:36.000000000 -0600 @@ -1610,11 +1610,35 @@ %{nil} # +# This macro defines a %%posttrans script for a kernel package. +# %%kernel_variant_posttrans [-v <subpackage>] [-s <s> -r <r>] <mkinitrd-args> +# More text can follow to go at the end of this variant's %%posttrans. +# +%define kernel_variant_posttrans(v:) \ +%{expand:%%posttrans %{?-v*}}\ +for d in /etc/kernel/postinst.d /etc/kernel/postinst.d/%{KVERREL}%{?-v*} ; do \ + if [ -d "${d}" ]; then \ + for f in $(ls ${d}/); do \ + [ -x "${d}/${f}" ] && "${d}/${f}" %{KVERREL}%{?-v*} /boot/vmlinuz-%{KVERREL}%{?-v*} \ + done \ + fi \ +done \ +exit 0\ +%{nil} + +# # This macro defines a %%preun script for a kernel package. # %%kernel_variant_preun <subpackage> # %define kernel_variant_preun() \ %{expand:%%preun %{?1}}\ +for d in /etc/kernel/prerm.d /etc/kernel/prerm.d/%{KVERREL}%{?1} ; do \ + if [ -d "${d}" ]; then \ + for f in $(ls ${d}/); do \ + [ -x "${d}/${f}" ] && "${d}/${f}" %{KVERREL}%{?1} /boot/vmlinuz-%{KVERREL}%{?1} \ + done \ + fi \ +done \ /sbin/new-kernel-pkg --rminitrd --rmmoddep --remove %{KVERREL}%{?1} || exit $?\ #if [ -x /sbin/weak-modules ]\ #then\ @@ -1624,12 +1648,15 @@ %kernel_variant_preun %kernel_variant_post -s kernel-smp -r kernel +%kernel_variant_posttrans %kernel_variant_preun smp %kernel_variant_post -v smp +%kernel_variant_posttrans -v smp %kernel_variant_preun PAE %kernel_variant_post -v PAE -s kernel-smp -r kernel-PAE +%kernel_variant_posttrans -v PAE %kernel_variant_preun debug %kernel_variant_post -v debug @@ -1644,6 +1671,8 @@ /sbin/ldconfig -X || exit $? fi +%kernel_variant_posttrans -v xen + ### ### file lists ###
