Package: aufs-source Version: 0+20090302-2.1 Severity: wishlist Hi
Trying to compile aufs-source 0+20090302-2.1 against kernel 2.6.31(-rc5-git2) fails with the following error message: $ mkdir -p /tmp/pkg/usr_src ; cd /tmp/pkg $ wget http://ftp.debian.org/debian/pool/main/a/aufs/aufs-source_0+20090302-2.1_all.deb [...] $ dpkg -x aufs-source_0+20090302-2.1_all.deb . $ tar -C usr_src/ -xjf usr/src/aufs.tar.bz2 $ LANG= MODULE_LOC=/tmp/pkg/usr_src/modules/ m-a -O --kvers-list $(uname -r) --kernel-dir /usr/src/linux-headers-$(uname -r)/ --userdir /tmp/pkg/ --text-mode build aufs /usr/bin/make -C /usr/src/linux-headers-2.6.31-rc5-sidux-amd64/ M=/tmp/pkg/usr_src/modules/aufs clean [...] /usr/bin/make -C /usr/src/linux-headers-2.6.31-rc5-sidux-amd64/ M=/tmp/pkg/usr_src/modules/aufs modules make[2]: Entering directory `/usr/src/linux-headers-2.6.31-rc5-sidux-amd64' [...] CC [M] /tmp/pkg/usr_src/modules/aufs/export.o /tmp/pkg/usr_src/modules/aufs/export.c: In function ‘au_do_mnt_get’: /tmp/pkg/usr_src/modules/aufs/export.c:284: error: dereferencing pointer to incomplete type make[3]: *** [/tmp/pkg/usr_src/modules/aufs/export.o] Error 1 make[2]: *** [_module_/tmp/pkg/usr_src/modules/aufs] Error 2 make[2]: Leaving directory `/usr/src/linux-headers-2.6.31-rc5-sidux-amd64' make[1]: *** [binary-modules] Error 2 make[1]: Leaving directory `/tmp/pkg/usr_src/modules/aufs' make: *** [kdist_build] Error 2 The attached patch has been build- and runtime tested in a live CD environment, although without nfs on any of the branches, and is confirmed to work with 2.6.30 and 2.6.31(-rc5-git2). While switching to the actively maintained aufs2 branch would indeed be a better option. I do not see any way to justify or avoid the excessive amount of symbol exports for kernel innards, which are totally inacceptable for kernel upstream and likely debian-kernel as well. But maybe aufs v1 can be kept on life support until VFS based unions mounts arrive mainline.

for kernel >= 2.6.31, we need to include linux/nsproxy.h to access
current->nsproxy->mnt_ns.
