fix modules_install via NFS

2009-01-07T20:44:20Z

Rafael reported: I get the following error from 'make modules_install' on my test boxes: HOSTCC firmware/ihex2fw /home/rafael/src/linux-2.6/firmware/ihex2fw.c:268: fatal error: opening dependency file firmware/.ihex2fw.d: Read-only file system compilation terminated. make[3]: *** [firmware/ihex2fw] Error 1 make[2]: *** [_modinst_post] Error 2 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 where the configuration is that the kernel is compiled on a build box with 'make O= -j5' and then is mounted over NFS read-only by each test box (full path to this directory is the same on the build box and on the test boxes). Then, I cd into , run 'make modules_install' and get the error above. The issue turns out to be that we when we install firmware pick up the list of firmware blobs from firmware/Makefile. And this triggers the Makefile rules to update ihex2fw. There were two solutions for this issue: 1) Move the list of firmware blobs to a separate file 2) Avoid ihex2fw rebuild by moving it to scripts As I seriously beleive that the list of firmware blobs should be done in a fundamental different way solution 2) was selected.

selinux: add support for installing a dummy policy (v2)

2008-08-26T22:54:08Z

In August 2006 I posted a patch generating a minimal SELinux policy. This week, David P. Quigley posted an updated version of that as a patch against the kernel. It also had nice logic for auto-installing the policy. Following is David's original patch intro (preserved especially bc it has stats on the generated policies): se interested in the changes there were only two significant changes. The first is that the iteration through the list of classes used NULL as a sentinel value. The problem with this is that the class_to_string array actually has NULL entries in its table as place holders for the user space object classes. The second change was that it would seem at some point the initial sids table was NULL terminated. This is no longer the case so that iteration has to be done on array length instead of looking for NULL. Some statistics on the policy that it generates: The policy consists of 523 lines which contain no blank lines. Of those 523 lines 453 of them are class, permission, and initial sid definitions. These lines are usually little to no concern to the policy developer since they will not be adding object classes or permissions. Of the remaining 70 lines there is one type, one role, and one user statement. The remaining lines are broken into three portions. The first group are TE allow rules which make up 29 of the remaining lines, the second is assignment of labels to the initial sids which consist of 27 lines, and file system labeling statements which are the remaining 11. In addition to the policy.conf generated there is a single file_contexts file containing two lines which labels the entire system with base_t. This policy generates a policy.23 binary that is 7920 bytes. (then a few versions later...): The new policy is 587 lines (stripped of blank lines) with 476 of those lines being the boilerplate that I mentioned last time. The remaining 111 lines have the 3 lines for type, user, and role, 70 lines for the allow rules (one for each object class including user space object classes), 27 lines to assign types to the initial sids, and 11 lines for file system labeling. The policy binary is 9194 bytes. Changelog: Aug 26: Added Documentation/SELinux.txt Aug 26: Incorporated a set of comments by Stephen Smalley: 1. auto-setup SELINUXTYPE=dummy 2. don't auto-install if selinux is enabled with non-dummy policy 3. don't re-compute policy version 4. /sbin/setfiles not /usr/sbin/setfiles Aug 22: As per JMorris comments, made sure make distclean cleans up the mdp directory. Removed a check for file_contexts which is now created in the same file as the check, making it superfluous. Signed-off-by: Serge Hallyn Signed-off-by: David Quigley Signed-off-by: James Morris

[PATCH] allow /proc/config.gz to be built as a module

2006-10-01T07:39:20Z

The driver for /proc/config.gz consumes rather a lot of memory and it is in fact possible to build it as a module. In some ways this is a bit risky, because the .config which is used for compiling kernel/configs.c isn't necessarily the same as the .config which was used to build vmlinux. But OTOH the potential memory savings are decent, and it'd be fairly dumb to build your configs.o with a different .config.

kbuild: modpost on vmlinux regardless of CONFIG_MODULES

2006-09-25T07:01:49Z

Based on patch from: Magnus Damm This has the advantage that all section mismatch checks are run regardless of modules being enabled or not. When running modpost on vmlinux output: MODPOST vmlinux When running modpost on modules output count of modules like this: MODPOST 5 modules Signed-off-by: Sam Ravnborg
