The latest -stable patch failed to compile for me:

Ubuntu 11.04 desktop (32 bit)
gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu4)
linux-2.6.32.45 (vanilla from kernel.org)
grsecurity-2.2.2-2.6.32.45-201108281458.patch

The kernel compiles successfully without the grsecurity patch. I also needed to correct the diagnostic-core.h vs. diagnostic.h discrepancy already noted for the 3.0.3 version of the patch.

Thank you for all that you do...

vmbus_channel_interface has to be __no_const, i'll fix it in the next patch, thanks.

Thank you. I updated to kernel version 2.6.32.46 and version grsecurity-2.2.2-2.6.32.46-201108300001.patch of the -stable patch. Now I get the following error:

Code: Select all: CC [M] drivers/staging/vt6656/hostap.o drivers/staging/vt6656/hostap.c: In function ‘hostap_enable_hostapd’: drivers/staging/vt6656/hostap.c:867:1: error: constified variable ‘apdev_netdev_ops’ cannot be local make[4]: *** [drivers/staging/vt6656/hostap.o] Error 1 make[3]: *** [drivers/staging/vt6656] Error 2 make[2]: *** [drivers/staging] Error 2 make[1]: *** [drivers] Error 2 make[1]: Leaving directory `/usr/src/linux-2.6.32.46' make: *** [debian/stamp/build/kernel] Error 2

Sorry to keep being a pest. These seem to be a recurring theme in the support forum. What's the general pattern to fixing them?

hmm, looks like some chunks didn't get backported to .32 from 3.0, i'll fix these up (you can look at the same file in 3.0 to see what's needed). in general, the constification plugin makes gcc detect certain constructs that we want to know about and fix one way or another. i hope there'll be a blog about it eventually, but for now just keep reporting them to us and we'll fix them up.

In case it was not expected, this problem persists in the grsecurity-2.2.2-2.6.32.46-201108301903.patch.

Thanks...
