Subject: [Bug 42812] New: kvm module has bogus kernel version check
Date: Wed, 22 Feb 2012 22:53:32 GMT [thread overview]
Message-ID: <bug-42812-28872@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=42812
Summary: kvm module has bogus kernel version check
Product: Virtualization
Version: unspecified
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: kvm
AssignedTo: virtualization_kvm@kernel-bugs.osdl.org
ReportedBy: mcbbzko@robuust.nl
Regression: No
In kvm-kmod-3.2, x86/external-module-compat.h, line 1102 the following check is
present:
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,37) || \
(LINUX_VERSION_CODE == KERNEL_VERSION(2,6,32) && KERNEL_EXTRAVERSION < 40)
The second half is bogus, since if kernel version is 2.6.32, it would have
matched the < 2.6.37 anyway.
Maybe the 2,6,32 should read 2,6,37 instead? (that would make more sense, but
may not be right!)
This check appears to be present since kvm-kmod release 3.0b, which makes it
unlikely many people tried it with 2.6.27.40+ kernels and found it to be a
problem...
