[Linux-stable-mirror] Patch "ARM: 8721/1: mm: dump: check hardware RO bit for LPAE" has been added to the 4.4-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ARM: 8721/1: mm: dump: check hardware RO bit for LPAE to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: arm-8721-1-mm-dump-check-hardware-ro-bit-for-lpae.patch and it can be found in the queue-4.4 subdirectory.

When CONFIG_ARM_LPAE is set, the PMD dump relies on the software read-only bit to determine whether a page is writable. This concealed a bug which left the kernel text section writable (AP2=0) while marked read-only in the software bit. In a kernel with the AP2 bug, the dump looks like this: ---[ Kernel Mapping ]--- 0xc0000000-0xc0200000 2M RW NX SHD 0xc0200000-0xc0600000 4M ro x SHD 0xc0600000-0xc0800000 2M ro NX SHD 0xc0800000-0xc4800000 64M RW NX SHD The fix is to check that the software and hardware bits are both set before displaying "ro". The dump then shows the true perms: ---[ Kernel Mapping ]--- 0xc0000000-0xc0200000 2M RW NX SHD 0xc0200000-0xc0600000 4M RW x SHD 0xc0600000-0xc0800000 2M RW NX SHD 0xc0800000-0xc4800000 64M RW NX SHD Fixes: ded947798469 ("ARM: 8109/1: mm: Modify pte_write and pmd_write logic for LPAE") Signed-off-by: Philip Derrin <philip(a)cog.systems> Tested-by: Neil Dick <neil(a)cog.systems> Reviewed-by: Kees Cook <keescook(a)chromium.org> Signed-off-by: Russell King <rmk+kernel(a)armlinux.org.uk> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- arch/arm/mm/dump.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) --- a/arch/arm/mm/dump.c +++ b/arch/arm/mm/dump.c @@ -126,8 +126,8 @@ static const struct prot_bits section_bi .val = PMD_SECT_USER, .set = "USR", }, { - .mask = L_PMD_SECT_RDONLY, - .val = L_PMD_SECT_RDONLY, + .mask = L_PMD_SECT_RDONLY | PMD_SECT_AP2, + .val = L_PMD_SECT_RDONLY | PMD_SECT_AP2, .set = "ro", .clear = "RW", #elif __LINUX_ARM_ARCH__ >= 6 Patches currently in stable-queue which might be from philip(a)cog.systems are queue-4.4/arm-8722-1-mm-make-strict_kernel_rwx-effective-for-lpae.patch queue-4.4/arm-8721-1-mm-dump-check-hardware-ro-bit-for-lpae.patch

[Linux-stable-mirror] Patch "x86/entry/64: Add missing irqflags tracing to native_load_gs_index()" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled x86/entry/64: Add missing irqflags tracing to native_load_gs_index() to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: x86-entry-64-add-missing-irqflags-tracing-to-native_load_gs_index.patch and it can be found in the queue-4.14 subdirectory.

Running this code with IRQs enabled (where dummy_lock is a spinlock): static void check_load_gs_index(void) { /* This will fail. */ load_gs_index(0xffff); spin_lock(&dummy_lock); spin_unlock(&dummy_lock); } Will generate a lockdep warning. The issue is that the actual write to %gs would cause an exception with IRQs disabled, and the exception handler would, as an inadvertent side effect, update irqflag tracing to reflect the IRQs-off status. native_load_gs_index() would then turn IRQs back on and return with irqflag tracing still thinking that IRQs were off. The dummy lock-and-unlock causes lockdep to notice the error and warn. Fix it by adding the missing tracing. Apparently nothing did this in a context where it mattered. I haven't tried to find a code path that would actually exhibit the warning if appropriately nasty user code were running. I suspect that the security impact of this bug is very, very low -- production systems don't run with lockdep enabled, and the warning is mostly harmless anyway. Found during a quick audit of the entry code to try to track down an unrelated bug that Ingo found in some still-in-development code.

When I added entry_SYSCALL_64_after_hwframe(), I left TRACE_IRQS_OFF before it. This means that users of entry_SYSCALL_64_after_hwframe() were responsible for invoking TRACE_IRQS_OFF, and the one and only user (Xen, added in the same commit) got it wrong. I think this would manifest as a warning if a Xen PV guest with CONFIG_DEBUG_LOCKDEP=y were used with context tracking. (The context tracking bit is to cause lockdep to get invoked before we turn IRQs back on.) I haven't tested that for real yet because I can't get a kernel configured like that to boot at all on Xen PV. Move TRACE_IRQS_OFF below the label.

When crosvm is used to boot a kernel as a VM, the SMP MP-table is found at physical address 0x0. This causes mpf_base to be set to 0 and a subsequent "if (!mpf_base)" check in default_get_smp_config() results in the MP-table not being parsed. Further into the boot this results in an oops when attempting a read_apic_id(). Add a boolean variable that is set to true when the MP-table is found. Use this variable for testing if the MP-table was found so that even a value of 0 for mpf_base will result in continued parsing of the MP-table.

Commit a5df70c35 hides the in_tx/in_tx_cp attributes when RTM is not available, but the TSX events are still available in sysfs. Due to the missing attributes the event parser fails on those files. Don't show the TSX events in sysfs when RTM is not available on Haswell/Broadwell/Skylake.
