2018-08-22net: hns: fix length and page_offset overflow when CONFIG_ARM64_64K_PAGESHuazhong Tan1-3/+3
When enable the config item "CONFIG_ARM64_64K_PAGES", the size of PAGE_SIZE is 65536(64K). But the type of length and page_offset are u16, they will overflow. So change them to u32.

Kevin Yang says: ==================== tcp_bbr: PROBE_RTT minor bug fixes This series includes two minor bug fixes for the TCP BBR PROBE_RTT mechanism, and one preparatory patch: (1) A preparatory patch to reorganize the PROBE_RTT logic by refactoring (into its own function) the code to exit PROBE_RTT, since the next patch will be using that code in a new context. (2) Fix: When BBR restarts from idle and if BBR is in PROBE_RTT mode, BBR should check if it's time to exit PROBE_RTT. If yes, then BBR should exit PROBE_RTT mode and restore the cwnd to its full value. (3) Fix: Apply the PROBE_RTT cwnd cap even if the count of fully-ACKed packets is 0. ==================== Signed-off-by: David S. Miller <[email protected]>
2018-08-22tcp_bbr: apply PROBE_RTT cwnd cap even if acked==0Kevin Yang1-2/+2
This commit fixes a corner case where TCP BBR would enter PROBE_RTT mode but not reduce its cwnd. If a TCP receiver ACKed less than one full segment, the number of delivered/acked packets was 0, so that bbr_set_cwnd() would short-circuit and exit early, without cutting cwnd to the value we want for PROBE_RTT. The fix is to instead make sure that even when 0 full packets are ACKed, we do apply all the appropriate caps, including the cap that applies in PROBE_RTT mode.

2018-08-22ipv4: tcp: send zero IPID for RST and ACK sent in SYN-RECV and TIME-WAIT stateEric Dumazet1-0/+6
tcp uses per-cpu (and per namespace) sockets (net->ipv4.tcp_sk) internally to send some control packets. 1) RST packets, through tcp_v4_send_reset() 2) ACK packets in SYN-RECV and TIME-WAIT state, through tcp_v4_send_ack() These packets assert IP_DF, and also use the hashed IP ident generator to provide an IPv4 ID number. Geoff Alexander reported this could be used to build off-path attacks. These packets should not be fragmented, since their size is smaller than IPV4_MIN_MTU. Only some tunneled paths could eventually have to fragment, regardless of inner IPID. We really can use zero IPID, to address the flaw, and as a bonus, avoid a couple of atomic operations in ip_idents_reserve() Signed-off-by: Eric Dumazet <[email protected]> Reported-by: Geoff Alexander <[email protected]> Tested-by: Geoff Alexander <[email protected]> Signed-off-by: David S.

2018-08-22sch_cake: Fix TC filter flow override and expand it to hosts as wellToke Høiland-Jørgensen1-4/+19
The TC filter flow mapping override completely skipped the call to cake_hash(); however that meant that the internal state was not being updated, which ultimately leads to deadlocks in some configurations. Fix that by passing the overridden flow ID into cake_hash() instead so it can react appropriately. In addition, the major number of the class ID can now be set to override the host mapping in host isolation mode. If both host and flow are overridden (or if the respective modes are disabled), flow dissection and hashing will be skipped entirely; otherwise, the hashing will be kept for the portions that are not set by the filter.

2018-08-21act_ife: fix a potential deadlockCong Wang1-13/+21
use_all_metadata() acquires read_lock(&ife_mod_lock), then calls add_metainfo() which calls find_ife_oplist() which acquires the same lock again. Deadlock! Introduce __add_metainfo() which accepts struct tcf_meta_ops *ops as an additional parameter and let its callers to decide how to find it. For use_all_metadata(), it already has ops, no need to find it again, just call __add_metainfo() directly. And, as ife_mod_lock is only needed for find_ife_oplist(), this means we can make non-atomic allocation for populate_metalist() now.

tcf_action_put_many() is mostly called to clean up actions on failure path, but tcf_action_put_many(&actions[acts_deleted]) is used in the ugliest way: it passes a slice of the array and uses an additional NULL at the end to avoid out-of-bound access. acts_deleted is completely unnecessary since we can teach tcf_action_put_many() scan the whole array and checks against NULL pointer. Which also means tcf_action_delete() should set deleted action pointers to NULL to avoid double free.

2018-08-19net: sched: always disable bh when taking tcf_lockVlad Buslov7-44/+47
Recently, ops->init() and ops->dump() of all actions were modified to always obtain tcf_lock when accessing private action state. Actions that don't depend on tcf_lock for synchronization with their data path use non-bh locking API. However, tcf_lock is also used to protect rate estimator stats in softirq context by timer callback. Change ops->init() and ops->dump() of all actions to disable bh when using tcf_lock to prevent deadlock reported by following lockdep warning: [ 105.470398] ================================ [ 105.475014] WARNING: inconsistent lock state [ 105.479628] 4.18.0-rc8+ #664 Not tainted [ 105.483897] -------------------------------- [ 105.488511] inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} usage.

git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull RISC-V updates from Palmer Dabbelt: "This contains some major improvements to the RISC-V port, including the necessary interrupt controller and timer support to actually make it to userspace. Support for three devices has been added: - the ISA-mandated timers on RISC-V systems. - the ISA-mandated first-level interrupt controller on RISC-V systems, which is handled as part of our core arch code because it's very small and tightly tied to the ISA. - SiFive's platform-level interrupt controller, which talks to the actual devices. In addition to these new devices, there are a handful of cleanups all over the RISC-V tree: - build fixes for various configurations: * A fix to the vDSO build's makefile so it respects CFLAGS. * The addition of __lshrti3, a libgcc derived function necessary for some 32-bit configurations. * !SMP && PERF_EVENTS - Cleanups to the arch code to remove the remnants of old versions of the drivers that were just properly submitted. * Some dead code from the timer driver, most of which wasn't ever even compiled. * Cleanups of some interrupt #defines, which are now local to the interrupt handling code. - Fixes to ptrace(), which while not being sufficient to fully make GDB work are at least sufficient to get simple GDB tasks to work. - Early printk support via RISC-V's architecturally mandated SBI console device. - A fix to our early debug trap handler to ensure it's always aligned. These patches have all been through a fairly extensive review process, but as this enables a whole pile of functionality (ie, userspace) I'm confident we'll need to submit a few more patches. The only concrete issues I know about are the sys_riscv_flush_icache patches, but as I managed to screw those up on Friday I figured it'd be best to let them bake another week. This tag boots a Fedora root filesystem on QEMU's master branch for me, and before this morning's rebase (from 4.18-rc8 to 4.18) it booted on the HiFive Unleashed.
