* Add '-fno-delete-null-pointer-checks' to gcc CFLAGSEugene Teo2009-07-161-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Turning on this flag could prevent the compiler from optimising away some "useless" checks for null pointers. Such bugs can sometimes become exploitable at compile time because of the -O2 optimisation. See http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Optimize-Options.html An example that clearly shows this 'problem' is commit 6bf67672. static void __devexit agnx_pci_remove(struct pci_dev *pdev) { struct ieee80211_hw *dev = pci_get_drvdata(pdev); - struct agnx_priv *priv = dev->priv; + struct agnx_priv *priv; AGNX_TRACE; if (!dev) return; + priv = dev->priv; By reverting this patch, and compile it with and without -fno-delete-null-pointer-checks flag, we can see that the check for dev is compiled away. call printk # - testq %r12, %r12 # dev - je .L94 #, movq %r12, %rdi # dev, Clearly the 'fix' is to stop using dev before it is tested, but building with -fno-delete-null-pointer-checks flag at least makes it harder to abuse.

* Don't use '-fwrapv' compiler option: it's buggy in gcc-4.1.xLinus Torvalds2009-07-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This causes kernel images that don't run init to completion with certain broken gcc versions. This fixes kernel bugzilla entry: http://bugzilla.kernel.org/show_bug.cgi?id=13012 I suspect the gcc problem is this: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28230 Fix the problem by using the -fno-strict-overflow flag instead, which not only does not exist in the known-to-be-broken versions of gcc (it was introduced later than fwrapv), but seems to be much less disturbing to gcc too: the difference in the generated code by -fno-strict-overflow are smaller (compared to using neither flag) than when using -fwrapv.

* Kbuild: Disable the -Wformat-security gcc flagFloris Kraak2009-06-271-1/+2
| | | | | | | | | | | | Some distributions have enabled the gcc flag -Wformat-security by default. This results in a number of warnings about format arguments to functions, sometimes in cases where fixing the warning is not likely to actually fix a bug. Instead of hand patching a dozens of places (possibly more) that produce warnings that get ignored anyway we just turn off the flag in the Makefile.

* gcov: add gcov profiling infrastructurePeter Oberparleiter2009-06-181-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable the use of GCC's coverage testing tool gcov [1] with the Linux kernel. gcov may be useful for: * debugging (has this code been reached at all?) * test improvement (how do I change my test to cover these lines?) * minimizing kernel configurations (do I need this option if the associated code is never run?) The profiling patch incorporates the following changes: * change kbuild to include profiling flags * provide functions needed by profiling code * present profiling data as files in debugfs Note that on some architectures, enabling gcc's profiling option "-fprofile-arcs" for the entire kernel may trigger compile/link/ run-time problems, some of which are caused by toolchain bugs and others which require adjustment of architecture code. For this reason profiling the entire kernel is initially restricted to those architectures for which it is known to work without changes. This restriction can be lifted once an architecture has been tested and found compatible with gcc's profiling. Profiling of single files or directories is still available on all platforms (see config help text).

| * kbuild: remove extra ifdef/endif of top MakefileCheng Renquan2009-06-091-17/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GNU make's origin function know undefined variable well, so the outer ifdef/endif conditional checking is unneeded. From `info make` documentation, origin will return `undefined' if VARIABLE was never defined. `command line' if VARIABLE was defined on the command line. ... Therefore, $(origin V) will get a value anyway, killing ifdef/endif is viable and safe. Furthermore, I've checked the minimal requirements from Documentation/Changes is GNU make 3.79.1, and that version of GNU make has support of origin function well already, so now it's safe to kill the outer conditional checking, without upgrading the minimal requirements.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make it possible for the linker to discard local symbols from vmlinux as they cause vmlinux to balloon when CONFIG_KALLSYMS=y and they cause dump_stack() and get_wchan() to produce useless information under some circumstances. With this we add a config option (CONFIG_STRIP_ASM_SYMS) that will cause the build to supply -X to the linker to tell it to strip temporary local symbols. This doesn't seem to cause gdb any problems.

This is due to KERNELRELEASE being different when the initial make is run and when make is run from rpmbuild. mkspec creates kernel.spec using KERNELRELEASE: <mkspec> echo "%files" echo '%defattr (-, root, root)' echo "%dir /lib/modules" echo "/lib/modules/$KERNELRELEASE" echo "/lib/firmware" echo "/boot/*" echo "" </mkspec> When CONFIG_LOCALVERSION_AUTO=y scripts/setlocalversion is called and grabs any additional version info from SCM. Next, the srctree is tarred up and SCM information is excluded. rpmbuild reruns make and in the process generates a new include/config/kernel.release and thus a new KERNELRELEASE. However this time the SCM information is gone so KERNELRELEASE no longer has the additional version information. When "make modules_install" runs, it uses the new KERNELRELEASE value to determine where to install the modules. This conflicts with where the spec file assumes they are going because of the mis-matching KERNELRELEASE versions. <snippet> + INSTALL_MOD_PATH=/var/tmp/kernel-2.6.29rc4tip01479g5d85422-root + make -j16 modules_install INSTALL crypto/aead.ko INSTALL crypto/cbc.ko INSTALL crypto/chainiv.ko INSTALL crypto/crc32c.ko INSTALL crypto/crypto_algapi.ko INSTALL crypto/crypto_blkcipher.ko INSTALL crypto/crypto_hash.ko INSTALL crypto/cryptomgr.ko INSTALL crypto/ecb.ko INSTALL crypto/eseqiv.ko INSTALL crypto/krng.ko INSTALL crypto/md5.ko INSTALL crypto/pcbc.ko INSTALL crypto/rng.ko INSTALL drivers/block/cciss.ko INSTALL drivers/hid/hid-dummy.ko INSTALL drivers/scsi/iscsi_tcp.ko INSTALL drivers/scsi/libiscsi.ko INSTALL drivers/scsi/libiscsi_tcp.ko INSTALL drivers/scsi/scsi_transport_iscsi.ko INSTALL drivers/scsi/scsi_wait_scan.ko INSTALL fs/lockd/lockd.ko INSTALL fs/nfs/nfs.ko INSTALL fs/nfsd/nfsd.ko INSTALL lib/libcrc32c.ko INSTALL net/sunrpc/sunrpc.ko DEPMOD 2.6.29-rc4-tip + cp arch/x86/boot/bzImage /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/vmlinuz-2.6.29-rc4-tip-01479-g5d85422 + cp System.map /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/System.map-2.6.29-rc4-tip-01479-g5d85422 + cp .config /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/config-2.6.29-rc4-tip-01479-g5d85422 + cp vmlinux vmlinux.orig + bzip2 -9 vmlinux + mv vmlinux.bz2 /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/vmlinux-2.6.29-rc4-tip-01479-g5d85422.bz2 + mv vmlinux.orig vmlinux + /usr/lib/rpm/brp-compress Processing files: kernel-2.6.29rc4tip01479g5d85422-2 error: File not found: /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/lib/modules/2.6.29-rc4-tip-01479-g5d85422 RPM build errors: File not found: /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/lib/modules/2.6.29-rc4-tip-01479-g5d85422 make[1]: *** [rpm] Error 1 make: *** [rpm] Error 2 </snippet> I have tested this patch on git -tip, Linus' git tree, and the kernel.org tar files, both with and without CONFIG_LOCALVERSION_AUTO=y.

* | | | | kbuild: create the source symlink earlier in the objdirAndi Kleen2009-02-151-1/+1
| |/ / / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's useful to already have the source symlink in a objdir when one just runs make *config. Then one can do mkdir obj-allyes cd obj-allyes make -C ../sourcedir O=$(pwd) allyesconfig ./source/scripts/config --disable debug_info make CC=icecc -j18 without having to interrupt the make first just to get the source symlink.
