[kbuild-devel] make install with nfs root_squash
Hi, I'm encountering some annoyances building (out-of-tree) modules on an NFS filesystem. The NFS filesystem is exported with the default root_squash option. When I build as a normal user, then su to root to do the final make modules_install, it fails with permission denied. For example, modules_install tries to delete all the files in the .tmp_versions subdirectory, or tries to write to Module.symvers, but the nfs root_squash prevents root from having any special write permissions. I've verified this problem with 2.6.18 and 2.6.20 kernels. It didn't happen with the old kernel I was using (2.6.8). Is there any reason that a make modules_install has to modify files in the source tree? -- Frank pgpNRZi4CU9QN.pgp Description: PGP signature - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

[kbuild-devel] [PATCH] modpost bug with multiple SUBDIRS and kernel 2.6.17.6
Hi kbuild maintainers, Attached is a one-line patch to scripts/Makefile.modpost which fixes a compilation problem I had building some out-of-tree modules (linux-gpib) against a 2.6.17.6 kernel. The problem was KBUILD_EXTMOD was set to SUBDIRS, which contained paths to multiple directories. This made modulesymfile get set to a bad value. I used $(firstword ...) to set modulesymfile using only the first directory in KBUILD_EXTMOD, like the way MODVERDIR is set in the top-level Makefile. -- Frank --- Makefile.modpost.original 2006-07-15 15:00:43.0 -0400 +++ Makefile.modpost 2006-07-19 13:07:45.648572000 -0400 @@ -40,7 +40,7 @@ include scripts/Makefile.lib kernelsymfile := $(objtree)/Module.symvers -modulesymfile := $(KBUILD_EXTMOD)/Modules.symvers +modulesymfile := $(firstword $(KBUILD_EXTMOD))/Modules.symvers # Step 1), find all modules listed in $(MODVERDIR)/ __modules := $(sort $(shell grep -h '\.ko' /dev/null $(wildcard $(MODVERDIR)/*.mod))) pgpS76wJYgxlG.pgp Description: PGP signature - Take Surveys.

It is a realistic case for an embedded CD-RW appliance. Or alternatively, you want to enable SCSI code, with no hardware driver, because you are going to build pcmcia, which builds the scsi drivers only if CONFIG_SCSI is defined, and the user might put in an Adaptec 1460B or 1480 scsi card into your pcmcia slot. Both of these 'problems' assume that you can have IDE or PCMCIA on these particular boxes. Does anyone know if that's actually true? The answer is: no, you can't. I found a feature list for the MVME147 on the web at http://www.mcg.mot.com/cfm/templates/article.cfm?PageID=1095. It confirmed what thought I remembered from the Motorola site; no PCMCIA, no IDE/ATAPI. As a matter of fact neither of these technologies existed yet when the board was being designed in the mid-1980s. But it is a VME board. That means you can put a SCSI controller on the VME bus (and these do exist, I have one right here). Frank (The article I found is kind of interesting. It's a dissection of the MVME147's design and history...narrated in first person.) In any case, if this *had* been a problem, the right fix IMO would have been to split the SCSI symbol into SCSI and SCSI_DRIVERS and have constraints that would make SCSI and the presence of any SCSI card imply SCSI_DRIVERS. -- a href=http://www.tuxedo.org/~esr/;Eric S.
