liblockdep: Fix undefined symbol prandom_u32
__lock_pin_lock() now calls prandom_u32() which is not defined in

cpupower: Fix checks for CPU existence
Calls to cpufreq_cpu_exists(cpu) were converted to
cpupower_is_cpu_online(cpu) when libcpupower was introduced and the
former function was deleted. However, cpupower_is_cpu_online()
returns 1 on success whereas cpufreq_cpu_exists() returned 0 on
success. It also does not distinguish physically absent and offline
CPUs, and does not set errno.
In cpufreq-set, test for cpupower_is_cpu_online(cpu) != 1.
In cpufreq-bench, which prints an error message for offline CPUs,
properly distinguish and report the zero and negative cases.

net: add recursion limit to GRO
Currently, GRO can do unlimited recursion through the gro_receive
handlers. This was fixed for tunneling protocols by limiting tunnel GRO
to one level with encap_mark, but both VLAN and TEB still have this
problem. Thus, the kernel is vulnerable to a stack overflow, if we
receive a packet composed entirely of VLAN headers.
This patch adds a recursion counter to the GRO layer to prevent stack
overflow. When a gro_receive function hits the recursion limit, GRO is
aborted for this skb and it is processed normally.

ptrace: being capable wrt a process requires mapped uids/gids
ptrace_has_cap() checks whether the current process should be
treated as having a certain capability for ptrace checks
against another process. Until now, this was equivalent to
has_ns_capability(current, target_ns, CAP_SYS_PTRACE).
However, if a root-owned process wants to enter a user
namespace for some reason without knowing who owns it and
therefore can't change to the namespace owner's uid and gid
before entering, as soon as it has entered the namespace,
the namespace owner can attach to it via ptrace and thereby
gain access to its uid and gid.
While it is possible for the entering process to switch to
the uid of a claimed namespace owner before entering,
causing the attempt to enter to fail if the claimed uid is
wrong, this doesn't solve the problem of determining an
appropriate gid.
With this change, the entering process can first enter the
namespace and then safely inspect the namespace's
properties, e.g. through /proc/self/{uid_map,gid_map},
assuming that the namespace owner doesn't have access to
uid 0.
Changed in v2: The caller needs to be capable in the
namespace into which tcred's uids/gids can be mapped.

increased the maximal time the slab_mutex can be held.
To prevent that from happening, let's use a special ordered single
threaded workqueue for kmem cache creation. This shouldn't introduce any
functional changes regarding how kmem caches are created, as the work
function holds the global slab_mutex during its whole runtime anyway,
making it impossible to run more than one work at a time. By using a
single threaded workqueue, we just avoid creating a thread per each
work. Ordering is required to avoid a situation when a cgroup's work is
put off indefinitely because there are other cgroups to serve, in other
words to guarantee fairness.

Sh*t, I missed this during the review. So your filesystem image (thank
you!) had this to say:
debugfs> stats
Inode size: 256
debugfs> stat <8>
Size of extra inode fields: 0
Basically, a 128-byte inode inside a filesystem that allocated 256 bytes
for each inode. As you point out, the old code would checksum the entire
allocated space, whether or not the inode core used it. Obviously, you
want this since inline extended attributes live in that space:
csum = ext4_chksum(sbi, ei->i_csum_seed, (__u8 *)raw,
EXT4_INODE_SIZE(inode->i_sb));
The new code, on the other hand, carefully checksums around the
i_checksum fields and only bothers to checksum the space between the end
of i_checksum_hi and the end of the allocated space if the inode core is
big enough to store i_checksum_hi. Since we allocated 256 bytes for
each inode, we checksum the first two bytes after byte 128
(EXT4_GOOD_OLD_INODE_SIZE), but then we see that i_extra_size == 0 so we
never bother to checksum anything after that. This is of course wrong
since we no longer checksum the xattr space and we've deviated from the
pre-4.7.4 (documented) on-disk format.
*FORTUNATELY* since the root inode fails the read verifier, the file (in
this case the root dir) can't be modified and therefore nothing has been
corrupted. Especially fortunate for you, the fs won't mount, reducing
the chances that any serious damage has occurred.
I /think/ the fix in this case is to hoist the last ext4_chksum call
out of the EXT4_FITS_IN_INODE blob:
if (EXT4_INODE_SIZE(inode->i_sb) > EXT4_GOOD_OLD_INODE_SIZE) {
offset = offsetof(struct ext4_inode, i_checksum_hi);
csum = ext4_chksum(sbi, csum, (__u8 *)raw +
EXT4_GOOD_OLD_INODE_SIZE,
offset - EXT4_GOOD_OLD_INODE_SIZE);
if (EXT4_FITS_IN_INODE(raw, ei, i_checksum_hi)) {
csum = ext4_chksum(sbi, csum, (__u8 *)&dummy_csum,
csum_size);
offset += csum_size;
}
csum = ext4_chksum(sbi, csum, (__u8 *)raw + offset,
EXT4_INODE_SIZE(inode->i_sb) - offset);
}
Can you give that a try?

Hard to say, but this bug only affects inodes with 0 < i_extra_size <= 4
i.e. 128 < inode-core-size <= 130. Maybe an old ext3 fs that was
created with 256 bytes per inode but inode-core-size of 128?
Uck. Sorry about this mess.

x86: Make x32 syscall support conditional on a kernel parameter
Enabling x32 in the standard amd64 kernel would increase its attack
surface while provide no benefit to the vast majority of its users.
No-one seems interested in regularly checking for vulnerabilities
specific to x32 (at least no-one with a white hat).
Still, adding another flavour just to turn on x32 seems wasteful. And
the only differences on syscall entry are two instructions (mask out
the x32 flag and compare the syscall number).
So pad the standard comparison with a nop and add a kernel parameter
"syscall.x32" which controls whether this is replaced with the x32
version at boot time. Add a Kconfig parameter to set the default.

service or privilege escalation. We can mitigate the effect of any
remaining vulnerabilities in such protocols by preventing unprivileged
users from loading the modules, so that they are only exploitable on
systems where the administrator has chosen to load the protocol.
The 'af_802154' (IEEE 802.15.4) protocol is not widely used, was
not present in the 'lenny' kernel, and seems to receive only sporadic
maintenance. Therefore disable auto-loading.

radeon: Firmware is required for DRM and KMS on R600 onward
radeon requires firmware/microcode for the GPU in all chips, but for
newer chips (apparently R600 'Evergreen' onward) it also expects
firmware for the memory controller and other sub-blocks.
radeon attempts to gracefully fall back and disable some features if
the firmware is not available, but becomes unstable - the framebuffer
and/or system memory may be corrupted, or the display may stay black.
Therefore, perform a basic check for the existence of
/lib/firmware/radeon when a device is probed, and abort if it is
missing, except for the pre-R600 case.

firmware: Remove redundant log messages from drivers

firmware_class: Log every success and failure against given device
The hundreds of users of request_firmware() have nearly as many
different log formats for reporting failures. They also have only the
vaguest hint as to what went wrong; only firmware_class really knows
that. Therefore, add specific log messages for the failure modes that
aren't currently logged.
In case of a driver that tries multiple names, this may result in the
impression that it failed to initialise. Therefore, also log successes.
This makes many error messages in drivers redundant, which will be
removed in later patches.
This does not cover the case where we fall back to a user-mode helper
(which is no longer enabled in Debian).
NOTE: hw-detect will depend on the "firmware: failed to load %s (%d)\n"
format to detect missing firmware.

iwlwifi: Do not request unreleased firmware for IWL6000
The iwlwifi driver currently supports firmware API versions 4-6 for
these devices. It will request the file for the latest supported

version that has actually been released is 4, so we expect the

not easy to detect that this particular failure is harmless. So stop
