-Subject: [PATCH] r8169: remove the obsolete and incorrect AMD workaround
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This was introduced in commit 6dccd16 "r8169: merge with version
-6.001.00 of Realtek's r8169 driver". I did not find the version
-6.001.00 online, but in 6.002.00 or any later r8169 from Realtek
-this hunk is no longer present.
-
-Also commit 05af214 "r8169: fix Ethernet Hangup for RTL8110SC
-rev d" claims to have fixed this issue otherwise.
-
-The magic compare mask of 0xfffe000 is dubious as it masks
-parts of the Reserved part, and parts of the VLAN tag. But this
-does not make much sense as the VLAN tag parts are perfectly
-valid there. In matter of fact this seems to be triggered with
-any VLAN tagged packet as RxVlanTag bit is matched. I would
-suspect 0xfffe0000 was intended to test reserved part only.
-
-Finally, this hunk is evil as it can cause more packets to be
-handled than what was NAPI quota causing net/core/dev.c:
-net_rx_action(): WARN_ON_ONCE(work > weight) to trigger, and
-mess up the NAPI state causing device to hang.
-
-As result, any system using VLANs and having high receive
-traffic (so that NAPI poll budget limits rtl_rx) would result
-in device hang.

-Subject: [PATCH 1/2] sock_diag: Fix out-of-bounds access to
- sock_diag_handlers[]
-
-Userland can send a netlink message requesting SOCK_DIAG_BY_FAMILY
-with a family greater or equal then AF_MAX -- the array size of
-sock_diag_handlers[]. The current code does not test for this
-condition therefore is vulnerable to an out-of-bound access opening
-doors for a privilege escalation.

-Subject: [PATCH 2/2] net: fix infinite loop in __skb_recv_datagram()
-
-Tommi was fuzzing with trinity and reported the following problem :
-
-commit 3f518bf745 (datagram: Add offset argument to __skb_recv_datagram)
-missed that a raw socket receive queue can contain skbs with no payload.
-
-We can loop in __skb_recv_datagram() with MSG_PEEK mode, because
-wait_for_packet() is not prepared to skip these skbs.

-+ This option also limits argv/env strings for suid/sgid binaries
-+ to 512KB to prevent a complete exhaustion of the stack entropy provided
-+ by ASLR. Finally, it places an 8MB stack resource limit on suid/sgid

-+ with the exact name of the module mentioned in the alert log.
-+ Alternatively, the administrator can add the module to the list

-+
-+ Modification of init scripts will most likely be needed on

-+ system can hide that entry even from root.
-+
-+ This option also prevents leaking of kernel addresses through
-+ several /proc entries.
-+
-+ Note that this option is only effective provided the following
-+ conditions are met:
-+ 1) The kernel using grsecurity is not precompiled by some distribution
-+ 2) You have also enabled GRKERNSEC_DMESG
-+ 3) You are using the RBAC system and hiding other files such as your
-+ kernel image and System.map. Alternatively, enabling this option
-+ causes the permissions on /boot, /lib/modules, and the kernel
-+ source directory to change at compile time to prevent
-+ reading by non-root users.

-+ activity in the kernel (from KERNEXEC/UDEREF/USERCOPY)
-+ or an OOPS occurs due to bad memory accesses, instead of just
-+ terminating the offending process (and potentially allowing
-+ a subsequent exploit from the same user), we will take one of two
-+ actions:
-+ If the user was root, we will panic the system
-+ If the user was non-root, we will log the attempt, terminate
-+ all processes owned by the user, then prevent them from creating

-+config PAX_MEMORY_SANITIZE
-+ bool "Sanitize all freed memory"
-+ default y if (GRKERNSEC_CONFIG_AUTO && GRKERNSEC_CONFIG_PRIORITY_SECURITY)
-+ depends on !HIBERNATION
-+ help
-+ By saying Y here the kernel will erase memory pages as soon as they
-+ are freed. This in turn reduces the lifetime of data stored in the
-+ pages, making it less likely that sensitive information such as
-+ passwords, cryptographic secrets, etc stay in memory for too long.
-+
-+ This is especially useful for programs whose runtime is short, long
-+ lived processes and the kernel itself benefit from this as long as
-+ they operate on whole memory pages and ensure timely freeing of pages
-+ that may hold sensitive information.
-+
-+ The tradeoff is performance impact, on a single CPU system kernel
-+ compilation sees a 3% slowdown, other systems and workloads may vary
-+ and you are advised to test this feature on your expected workload
-+ before deploying it.
-+
-+ Note that this feature does not protect data stored in live pages,
-+ e.g., process memory swapped to disk may stay there for a long time.
-+
-+config PAX_MEMORY_STACKLEAK
-+ bool "Sanitize kernel stack"
-+ default y if (GRKERNSEC_CONFIG_AUTO && GRKERNSEC_CONFIG_PRIORITY_SECURITY)
-+ depends on X86
-+ help
-+ By saying Y here the kernel will erase the kernel stack before it
-+ returns from a system call. This in turn reduces the information
-+ that a kernel stack leak bug can reveal.
-+
-+ Note that such a bug can still leak information that was put on
-+ the stack by the current system call (the one eventually triggering
-+ the bug) but traces of earlier system calls on the kernel stack
-+ cannot leak anymore.
-+
-+ The tradeoff is performance impact: on a single CPU system kernel
-+ compilation sees a 1% slowdown, other systems and workloads may vary
-+ and you are advised to test this feature on your expected workload
-+ before deploying it.
-+
-+ Note that the full feature requires a gcc with plugin support,
-+ i.e., gcc 4.5 or newer. You may need to install the supporting
-+ headers explicitly in addition to the normal gcc package. Using
-+ older gcc versions means that functions with large enough stack
-+ frames may leave uninitialized memory behind that may be exposed
-+ to a later syscall leaking the stack.
-+
-+config PAX_MEMORY_UDEREF
-+ bool "Prevent invalid userland pointer dereference"
-+ default y if GRKERNSEC_CONFIG_AUTO && (X86_32 || (X86_64 && GRKERNSEC_CONFIG_PRIORITY_SECURITY)) && (GRKERNSEC_CONFIG_VIRT_NONE || GRKERNSEC_CONFIG_VIRT_EPT)
-+ depends on X86 && !UML_X86 && !XEN
-+ select PAX_PER_CPU_PGD if X86_64
-+ help
-+ By saying Y here the kernel will be prevented from dereferencing
-+ userland pointers in contexts where the kernel expects only kernel
-+ pointers. This is both a useful runtime debugging feature and a
-+ security measure that prevents exploiting a class of kernel bugs.
-+
-+ The tradeoff is that some virtualization solutions may experience
-+ a huge slowdown and therefore you should not enable this feature
-+ for kernels meant to run in such environments. Whether a given VM
-+ solution is affected or not is best determined by simply trying it
-+ out, the performance impact will be obvious right on boot as this
-+ mechanism engages from very early on. A good rule of thumb is that
-+ VMs running on CPUs without hardware virtualization support (i.e.,
-+ the majority of IA-32 CPUs) will likely experience the slowdown.
-+
-+config PAX_REFCOUNT
-+ bool "Prevent various kernel object reference counter overflows"
-+ default y if GRKERNSEC_CONFIG_AUTO
-+ depends on GRKERNSEC && ((ARM && (CPU_32v6 || CPU_32v6K || CPU_32v7)) || SPARC64 || X86)
-+ help
-+ By saying Y here the kernel will detect and prevent overflowing
-+ various (but not all) kinds of object reference counters. Such
-+ overflows can normally occur due to bugs only and are often, if
-+ not always, exploitable.
-+
-+ The tradeoff is that data structures protected by an overflowed
-+ refcount will never be freed and therefore will leak memory. Note
-+ that this leak also happens even without this protection but in
-+ that case the overflow can eventually trigger the freeing of the
-+ data structure while it is still being used elsewhere, resulting
-+ in the exploitable situation that this feature prevents.
-+
-+ Since this has a negligible performance impact, you should enable
-+ this feature.
-+
-+config PAX_USERCOPY
-+ bool "Harden heap object copies between kernel and userland"
-+ default y if GRKERNSEC_CONFIG_AUTO
-+ depends on X86 || PPC || SPARC || ARM
-+ depends on GRKERNSEC && (SLAB || SLUB || SLOB)
-+ select PAX_USERCOPY_SLABS
-+ help
-+ By saying Y here the kernel will enforce the size of heap objects
-+ when they are copied in either direction between the kernel and
-+ userland, even if only a part of the heap object is copied.
-+
-+ Specifically, this checking prevents information leaking from the
-+ kernel heap during kernel to userland copies (if the kernel heap
-+ object is otherwise fully initialized) and prevents kernel heap
-+ overflows during userland to kernel copies.
-+
-+ Note that the current implementation provides the strictest bounds
-+ checks for the SLUB allocator.
-+
-+ Enabling this option also enables per-slab cache protection against
-+ data in a given cache being copied into/out of via userland
-+ accessors. Though the whitelist of regions will be reduced over
-+ time, it notably protects important data structures like task structs.
-+
-+ If frame pointers are enabled on x86, this option will also restrict
-+ copies into and out of the kernel stack to local variables within a
-+ single frame.
-+
-+ Since this has a negligible performance impact, you should enable
-+ this feature.
-+
-+config PAX_SIZE_OVERFLOW
-+ bool "Prevent various integer overflows in function size parameters"
-+ default y if GRKERNSEC_CONFIG_AUTO
-+ depends on X86
-+ help
-+ By saying Y here the kernel recomputes expressions of function
-+ arguments marked by a size_overflow attribute with double integer
-+ precision (DImode/TImode for 32/64 bit integer types).
-+
-+ The recomputed argument is checked against TYPE_MAX and an event
-+ is logged on overflow and the triggering process is killed.
-+
-+ Homepage: http://www.grsecurity.net/~ephox/overflow_plugin/
-+
-+ Note that the implementation requires a gcc with plugin support,
-+ i.e., gcc 4.5 or newer. You may need to install the supporting
-+ headers explicitly in addition to the normal gcc package.
-+
-+config PAX_LATENT_ENTROPY
-+ bool "Generate some entropy during boot"
-+ default y if GRKERNSEC_CONFIG_AUTO
-+ help
-+ By saying Y here the kernel will instrument early boot code to
-+ extract some entropy from both original and artificially created
-+ program state. This will help especially embedded systems where
-+ there is little 'natural' source of entropy normally. The cost
-+ is some slowdown of the boot process.
-+
-+ Note that the implementation requires a gcc with plugin support,
-+ i.e., gcc 4.5 or newer. You may need to install the supporting
-+ headers explicitly in addition to the normal gcc package.
-+
-+ Note that entropy extracted this way is not cryptographically
-+ secure!

-From: Ian Campbell <ian.campbell@citrix.com>
-Date: Fri, 11 Jan 2013 14:26:29 +0000
-Subject: [PATCH 1/4] xen/netback: shutdown the ring if it contains garbage.
-
-A buggy or malicious frontend should not be able to confuse netback.
-If we spot anything which is not as it should be then shutdown the
-device and don't try to continue with the ring in a potentially
-hostile state. Well behaved and non-hostile frontends will not be
-penalised.
-
-As well as making the existing checks for such errors fatal also add a
-new check that ensures that there isn't an insane number of requests
-on the ring (i.e. more than would fit in the ring). If the ring
-contains garbage then previously is was possible to loop over this
-insane number, getting an error each time and therefore not generating
-any more pending requests and therefore not exiting the loop in
-xen_netbk_tx_build_gops for an externded period.
-
-Also turn various netdev_dbg calls which no precipitate a fatal error
-into netdev_err, they are rate limited because the device is shutdown
-afterwards.
-
-This fixes at least one known DoS/softlockup of the backend domain.
