arm64's mm/mmu.c uses vm_area_add_early, struct vm_area and other definitions but relies on implict inclusion of linux/vmalloc.h which means that changes in other headers could break the build. Thus, add an explicit include. Acked-by: NArd Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: NTobias Klauser <tklauser@distanz.ch> Signed-off-by: NWill Deacon <will.deacon@arm.com>

Generic code expects show_regs() to dump the stack, but arm64's show_regs() does not. This makes it hard to debug softlockups and other issues that result in show_regs() being called. This patch updates arm64's show_regs() to dump the stack, as common code expects.

Generic code expects show_regs() to also dump the stack, but arm64's show_reg() does not do this. Some arm64 callers of show_regs() *only* want the registers dumped, without the stack. To enable generic code to work as expected, we need to make show_regs() dump the stack. Where we only want the registers dumped, we must use __show_regs(). This patch updates code to use __show_regs() where only registers are desired. A subsequent patch will modify show_regs().

Like arch/arm/, we inherit the READ_IMPLIES_EXEC personality flag across fork(). This is undesirable for a number of reasons: * ELF files that don't require executable stack can end up with it anyway * We end up performing un-necessary I-cache maintenance when mapping what should be non-executable pages * Restricting what is executable is generally desirable when defending against overflow attacks This patch clears the personality flag when setting up the personality for newly spwaned native tasks. Given that semi-recent AArch64 toolchains emit a non-executable PT_GNU_STACK header, userspace applications can already not rely on READ_IMPLIES_EXEC so shouldn't be adversely affected by this change.

ftrace use module_alloc() to allocate trampoline pages. The mapping of module_alloc() is RWX, which makes sense as the memory is written to right after allocation. But nothing makes these pages RO after writing to them. Add proper set_memory_rw/ro() calls to protect the trampolines after modification.

Add a testcase to test kprobes via ftrace interface with many concurrent kprobe events. This tries to add many kprobe events (up to 256) on kernel functions. To avoid making ftrace-based kprobes (kprobes on fentry), it skips first N bytes (on x86 N=5, on ppc or arm N=4) of function entry. After that, it enables all those events, disable it, and remove it. Since the unoptimization buffer reclaiming will be delayed, after removing events, it will wait enough time.

Instead, I suggested to add a refcount to the metrics themselves, being a standalone object (in particular, no reference to other objects) I tried to make this patch as small as possible to ease its backport, instead of being super clean. Note that we believe that only ipv4 dst need to take care of the metric refcount. But if this is wrong, this patch adds the basic infrastructure to extend this to other families.

This fix addresses two problems in the way the DSCP field is formulated on the encapsulating header of IPv6 tunnels. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=195661 1) The IPv6 tunneling code was manipulating the DSCP field of the encapsulating packet using the 32b flowlabel. Since the flowlabel is only the lower 20b it was incorrect to assume that the upper 12b containing the DSCP and ECN fields would remain intact when formulating the encapsulating header. This fix handles the 'inherit' and 'fixed-value' DSCP cases explicitly using the extant dsfield u8 variable. 2) The use of INET_ECN_encapsulate(0, dsfield) in ip6_tnl_xmit was incorrect and resulted in the DSCP value always being set to 0. Commit 90427ef5 ("ipv6: fix flow labels when the traffic class is non-0") caused the regression by masking out the flowlabel which exposed the incorrect handling of the DSCP portion of the flowlabel in ip6_tunnel and ip6_gre.

sometimes ICMP replies to INIT chunks are ignored by the client, even if the encapsulated SCTP headers match an open socket. This happens when the ICMP packet is carried by a paged skb: use skb_header_pointer() to read packet contents beyond the SCTP header, so that chunk header and initiate tag are validated correctly. v2: - don't use skb_header_pointer() to read the transport header, since icmp_socket_deliver() already puts these 8 bytes in the linear area. - change commit message to make specific reference to INIT chunks.

There is a race condition in llc_ui_bind if two or more processes/threads try to bind a same socket. If more processes/threads bind a same socket success that will lead to two problems, one is this action is not what we expected, another is will lead to kernel in unstable status or oops(in my simple test case, cause llc2.ko can't unload). The current code is test SOCK_ZAPPED bit to avoid a process to bind a same socket twice but that is can't avoid more processes/threads try to bind a same socket at the same time. So, add lock_sock in llc_ui_bind like others, such as llc_ui_connect. Signed-off-by: NLin Zhang <xiaolou4617@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

They have known firmware bugs. A fix is apparently in the works -- once fixed firmware is available, someone from Intel (Hi, Keith!) can adjust the quirk accordingly.
