Right now if we get a corrupted user stack frame we do a do_exit(SIGILL) which is not helpful. If under a debugger, this behavior causes the inferior process to exit. So the register and other state cannot be examined at the time of the event. Instead, conditionally log a rate limited kernel log message and then force a SIGSEGV. With bits and ideas borrowed (as usual) from powerpc. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Older versions of bintutils do not allow symbol math across different segments on sparc: ==================== Assembler messages: 99: Error: operation combines symbols in different segments ==================== This is controlled by whether or not DIFF_EXPR_OK is defined in gas/config/tc-*.h and for sparc this was not the case until mid-2017. So we have to patch between %stick and %tick another way. Do what powerpc does and emit two versions of the relevant functions, one using %tick and one using %stick, and patch the symbols in the dynamic symbol table.

Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull siginfo updates from Eric Biederman: "I have been slowly sorting out siginfo and this is the culmination of that work. The primary result is in several ways the signal infrastructure has been made less error prone. The code has been updated so that manually specifying SEND_SIG_FORCED is never necessary. The conversion to the new siginfo sending functions is now complete, which makes it difficult to send a signal without filling in the proper siginfo fields. At the tail end of the patchset comes the optimization of decreasing the size of struct siginfo in the kernel from 128 bytes to about 48 bytes on 64bit. The fundamental observation that enables this is by definition none of the known ways to use struct siginfo uses the extra bytes. This comes at the cost of a small user space observable difference. For the rare case of siginfo being injected into the kernel only what can be copied into kernel_siginfo is delivered to the destination, the rest of the bytes are set to 0. For cases where the signal and the si_code are known this is safe, because we know those bytes are not used. For cases where the signal and si_code combination is unknown the bits that won't fit into struct kernel_siginfo are tested to verify they are zero, and the send fails if they are not. I made an extensive search through userspace code and I could not find anything that would break because of the above change. If it turns out I did break something it will take just the revert of a single change to restore kernel_siginfo to the same size as userspace siginfo. Testing did reveal dependencies on preferring the signo passed to sigqueueinfo over si->signo, so bit the bullet and added the complexity necessary to handle that case. Testing also revealed bad things can happen if a negative signal number is passed into the system calls. Something no sane application will do but something a malicious program or a fuzzer might do. So I have fixed the code that performs the bounds checks to ensure negative signal numbers are handled" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (80 commits) signal: Guard against negative signal numbers in copy_siginfo_from_user32 signal: Guard against negative signal numbers in copy_siginfo_from_user signal: In sigqueueinfo prefer sig not si_signo signal: Use a smaller struct siginfo in the kernel signal: Distinguish between kernel_siginfo and siginfo signal: Introduce copy_siginfo_from_user and use it's return value signal: Remove the need for __ARCH_SI_PREABLE_SIZE and SI_PAD_SIZE signal: Fail sigqueueinfo if si_signo != sig signal/sparc: Move EMT_TAGOVF into the generic siginfo.h signal/unicore32: Use force_sig_fault where appropriate signal/unicore32: Generate siginfo in ucs32_notify_die signal/unicore32: Use send_sig_fault where appropriate signal/arc: Use force_sig_fault where appropriate signal/arc: Push siginfo generation into unhandled_exception signal/ia64: Use force_sig_fault where appropriate signal/ia64: Use the force_sig(SIGSEGV,...) in ia64_rt_sigreturn signal/ia64: Use the generic force_sigsegv in setup_frame signal/arm/kvm: Use send_sig_mceerr signal/arm: Use send_sig_fault where appropriate signal/arm: Use force_sig_fault where appropriate ...

The networking merge brought in the experimental support for the Qualcomm ath10k system NOC, which selects QCOM_QMI_HELPERS as a dependency.

With EDT model, SRTT no longer is inflated by pacing delays. This means that RTO and some other xmit timers might be setup incorrectly. This is particularly visible with either : - Very small enforced pacing rates (SO_MAX_PACING_RATE) - Reduced rto (from the default 200 ms) This can lead to TCP flows aborts in the worst case, or spurious retransmits in other cases. For example, this session gets far more throughput than the requested 80kbit : $ netperf -H 127.0.0.2 -l 100 -- -q 10000 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 540000 262144 262144 104.00 2.66 With the fix : $ netperf -H 127.0.0.2 -l 100 -- -q 10000 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 540000 262144 262144 104.00 0.12 EDT allows for better control of rtx timers, since TCP has a better idea of the earliest departure time of each skb in the rtx queue.

This reverts commit dd979b4d. This broke tcp_poll for SMC fallback: An AF_SMC socket establishes an internal TCP socket for the initial handshake with the remote peer. Whenever the SMC connection can not be established this TCP socket is used as a fallback. All socket operations on the SMC socket are then forwarded to the TCP socket. In case of poll, the file->private_data pointer references the SMC socket because the TCP socket has no file assigned. This causes tcp_poll to wait on the wrong socket.

There is a compatibility issue between RTL8211E implemented in Developerbox and netsec ethernet controller IP. Our MDIO controller stops MDC clock right after the write access, but RTL8211E expects MDC clock must be kept toggling for several clock cycle with MDIO high before entering the IDLE state. Without keeping clock after write access, write access is not correctly handled and register is not updated. To meet this requirement, netsec driver needs to issue dummy read(e.g. read PHYID1(offset 0x2) register) right after write access, to keep MDC clock. We think this compatibility issue is a problem specific to our MDIO controller and RTL8211E.

In ndo_stop, driver resets the netsec ethernet controller IP. When the netsec IP is reset, HW running mode turns to NRM mode and driver has to wait until this mode transition completes. But mode transition to NRM will not complete if the PHY is in normal operation state. Netsec IP requires PHY is in power down state when it is reset. This modification stops the PHY before resetting netsec. Together with this modification, phy_addr is stored in netsec_priv structure because ndev->phydev is not yet ready in ndo_init.

Pull RCU updates from Ingo Molnar: "The biggest change in this cycle is the conclusion of the big 'simplify RCU to two primary flavors' consolidation work - i.e. there's a single RCU flavor for any kernel variant (PREEMPT and !PREEMPT): - Consolidate the RCU-bh, RCU-preempt, and RCU-sched flavors into a single flavor similar to RCU-sched in !PREEMPT kernels and into a single flavor similar to RCU-preempt (but also waiting on preempt-disabled sequences of code) in PREEMPT kernels. This branch also includes a refactoring of rcu_{nmi,irq}_{enter,exit}() from Byungchul Park. - Now that there is only one RCU flavor in any given running kernel, the many "rsp" pointers are no longer required, and this cleanup series removes them. - This branch carries out additional cleanups made possible by the RCU flavor consolidation, including inlining now-trivial functions, updating comments and definitions, and removing now-unneeded rcutorture scenarios. - Now that there is only one flavor of RCU in any running kernel, there is also only on rcu_data structure per CPU. This means that the rcu_dynticks structure can be merged into the rcu_data structure, a task taken on by this branch. This branch also contains a -rt-related fix from Mike Galbraith. There were also other updates: - Documentation updates, including some good-eye catches from Joel Fernandes. - SRCU updates, most notably changes enabling call_srcu() to be invoked very early in the boot sequence. - Torture-test updates, including some preliminary work towards making rcutorture better able to find problems that result in insufficient grace-period forward progress. - Initial changes to RCU to better promote forward progress of grace periods, including fixing a bug found by Marius Hillenbrand and David Woodhouse, with the fix suggested by Peter Zijlstra" * 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (140 commits) srcu: Make early-boot call_srcu() reuse workqueue lists rcutorture: Test early boot call_srcu() srcu: Make call_srcu() available during very early boot rcu: Convert rcu_state.ofl_lock to raw_spinlock_t rcu: Remove obsolete ->dynticks_fqs and ->cond_resched_completed rcu: Switch ->dynticks to rcu_data structure, remove rcu_dynticks rcu: Switch dyntick nesting counters to rcu_data structure rcu: Switch urgent quiescent-state requests to rcu_data structure rcu: Switch lazy counts to rcu_data structure rcu: Switch last accelerate/advance to rcu_data structure rcu: Switch ->tick_nohz_enabled_snap to rcu_data structure rcu: Merge rcu_dynticks structure into rcu_data structure rcu: Remove unused rcu_dynticks_snap() from Tiny RCU rcu: Convert "1UL << x" to "BIT(x)" rcu: Avoid resched_cpu() when rescheduling the current CPU rcu: More aggressively enlist scheduler aid for nohz_full CPUs rcu: Compute jiffies_till_sched_qs from other kernel parameters rcu: Provide functions for determining if call_rcu() has been invoked rcu: Eliminate ->rcu_qs_ctr from the rcu_dynticks structure rcu: Motivate Tiny RCU forward progress ...
