2020-11-05io_uring: don't forget to task-cancel drained reqsPavel Begunkov
If there is a long-standing request of one task locking up execution of deferred requests, and the defer list contains requests of another task (all files-less), then a potential execution of __io_uring_task_cancel() by that another task will sleep until that first long-standing request completion, and that may take long. E.g. tsk1: req1/read(empty_pipe) -> tsk2: req(DRAIN) Then __io_uring_task_cancel(tsk2) waits for req1 completion. It seems we even can manufacture a complicated case with many tasks sharing many rings that can lock them forever. Cancel deferred requests for __io_uring_task_cancel() as well.

2020-11-05powerpc/8xx: Manage _PAGE_ACCESSED through APG bits in L1 entryChristophe Leroy
When _PAGE_ACCESSED is not set, a minor fault is expected. To do this, TLB miss exception ANDs _PAGE_PRESENT and _PAGE_ACCESSED into the L2 entry valid bit. To simplify the processing and reduce the number of instructions in TLB miss exceptions, manage it as an APG bit and get it next to _PAGE_GUARDED bit to allow a copy in one go. Then declare the corresponding groups as handling all accesses as user accesses. As the PP bits always define user as No Access, it will generate a fault.

2020-11-05powerpc/8xx: Always fault when _PAGE_ACCESSED is not setChristophe Leroy
The kernel expects pte_young() to work regardless of CONFIG_SWAP. Make sure a minor fault is taken to set _PAGE_ACCESSED when it is not already set, regardless of the selection of CONFIG_SWAP. This adds at least 3 instructions to the TLB miss exception handlers fast path. Following patch will reduce this overhead. Also update the rotation instruction to the correct number of bits to reflect all changes done to _PAGE_ACCESSED over time. Fixes: d069cb4373fe ("powerpc/8xx: Don't touch ACCESSED when no SWAP.")

2020-11-05powerpc: Use asm_goto_volatile for put_user()Michael Ellerman
Andreas reported that commit ee0a49a6870e ("powerpc/uaccess: Switch __put_user_size_allowed() to __put_user_asm_goto()") broke CLONE_CHILD_SETTID. Further inspection showed that the put_user() in schedule_tail() was missing entirely, the store not emitted by the compiler. <.schedule_tail>: mflr r0 std r0,16(r1) stdu r1,-112(r1) bl <.finish_task_switch> ld r9,2496(r3) cmpdi cr7,r9,0 bne cr7,<.schedule_tail+0x60> ld r3,392(r13) ld r9,1392(r3) cmpdi cr7,r9,0 beq cr7,<.schedule_tail+0x3c> li r4,0 li r5,0 bl <.__task_pid_nr_ns> nop bl <.calculate_sigpending> nop addi r1,r1,112 ld r0,16(r1) mtlr r0 blr nop nop nop bl <.__balance_callback> b <.schedule_tail+0x1c> Notice there are no stores other than to the stack. There should be a stw in there for the store to current->set_child_tid. This is only seen with GCC 4.9 era compilers (tested with 4.9.3 and 4.9.4), and only when CONFIG_PPC_KUAP is disabled. When CONFIG_PPC_KUAP=y, the inline asm that's part of the isync() and mtspr() inlined via allow_user_access() seems to be enough to avoid the bug. We already have a macro to work around this (or a similar bug), called asm_volatile_goto which includes an empty asm block to tickle the compiler into generating the right code. So use that. With this applied the code generation looks more like it will work: <.schedule_tail>: mflr r0 std r31,-8(r1) std r0,16(r1) stdu r1,-144(r1) std r3,112(r1) bl <._mcount> nop ld r3,112(r1) bl <.finish_task_switch> ld r9,2624(r3) cmpdi cr7,r9,0 bne cr7,<.schedule_tail+0xa0> ld r3,2408(r13) ld r31,1856(r3) cmpdi cr7,r31,0 beq cr7,<.schedule_tail+0x80> li r4,0 li r5,0 bl <.__task_pid_nr_ns> nop li r9,-1 clrldi r9,r9,12 cmpld cr7,r31,r9 bgt cr7,<.schedule_tail+0x80> lis r9,16 rldicr r9,r9,32,31 subf r9,r31,r9 cmpldi cr7,r9,3 ble cr7,<.schedule_tail+0x80> li r9,0 stw r3,0(r31) <-- stw nop bl <.calculate_sigpending> nop addi r1,r1,144 ld r0,16(r1) ld r31,-8(r1) mtlr r0 blr nop bl <.__balance_callback> b <.schedule_tail+0x30> Fixes: ee0a49a6870e ("powerpc/uaccess: Switch __put_user_size_allowed() to __put_user_asm_goto()") Reported-by: Andreas Schwab <schwab@linux-m68k.org> Tested-by: Andreas Schwab <schwab@linux-m68k.org> Suggested-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20201104111742.672142-1-mpe@ellerman.id.au

2020-11-04ceph: check session state after bumping session->s_seqJeff Layton
Some messages sent by the MDS entail a session sequence number increment, and the MDS will drop certain types of requests on the floor when the sequence numbers don't match. In particular, a REQUEST_CLOSE message can cross with one of the sequence morphing messages from the MDS which can cause the client to stall, waiting for a response that will never come. Originally, this meant an up to 5s delay before the recurring workqueue job kicked in and resent the request, but a recent change made it so that the client would never resend, causing a 60s stall unmounting and sometimes a blockisting event. Add a new helper for incrementing the session sequence and then testing to see whether a REQUEST_CLOSE needs to be resent, and move the handling of CEPH_MDS_SESSION_CLOSING into that function. Change all of the bare sequence counter increments to use the new helper. Reorganize check_session_state with a switch statement. It should no longer be called when the session is CLOSING, so throw a warning if it ever is (but still handle that case sanely).

2020-11-04PCI: mvebu: Fix duplicate resource requestsRob Herring
With commit 669cbc708122 ("PCI: Move DT resource setup into devm_pci_alloc_host_bridge()"), the DT 'ranges' is parsed and populated into resources when the host bridge is allocated. The resources are requested as well, but that happens a second time for the mvebu driver in mvebu_pcie_parse_request_resources(). We should only be requesting the additional resources added in mvebu_pcie_parse_request_resources(). These are not added by default because they use custom properties rather than standard DT address translation. Also, the bus ranges was also populated by default, so we can remove it from mvebu_pci_host_probe().

2020-11-04PCI: dwc: Restore ATU memory resource setup to use last entryRob Herring
Prior to commit 0f71c60ffd26 ("PCI: dwc: Remove storing of PCI resources"), the DWC driver was setting up the last memory resource rather than the first memory resource. This doesn't matter for most platforms which only have 1 memory resource, but it broke Tegra194 which has a 2nd (prefetchable) memory region that requires an ATU entry. The first region on Tegra194 relies on the default 1:1 pass-thru of outbound transactions and doesn't need an ATU entry.

git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can Marc Kleine-Budde says: ==================== pull-request: can 2020-11-03 The first two patches are by Oleksij Rempel and they add a generic can-controller Device Tree yaml binding and convert the text based binding of the flexcan driver to a yaml based binding. Zhang Changzhong's patch fixes a remove_proc_entry warning in the AF_CAN core. A patch by me fixes a kfree_skb() call from IRQ context in the rx-offload helper. Vincent Mailhol contributes a patch to prevent a call to kfree_skb() in hard IRQ context in can_get_echo_skb(). Oliver Hartkopp's patch fixes the length calculation for RTR CAN frames in the __can_get_echo_skb() helper. Oleksij Rempel's patch fixes a use-after-free that shows up with j1939 in can_create_echo_skb(). Yegor Yefremov contributes 4 patches to enhance the j1939 documentation. Zhang Changzhong's patch fixes a hanging task problem in j1939_sk_bind() if the netdev is down. Then there are three patches for the newly added CAN_ISOTP protocol. Geert Uytterhoeven enhances the kconfig help text. Oliver Hartkopp's patch adds missing RX timeout handling in listen-only mode and Colin Ian King's patch decreases the generated object code by 926 bytes. Zhang Changzhong contributes a patch for the ti_hecc driver that fixes the error path in the probe function. Navid Emamdoost's patch for the xilinx_can driver fixes the error handling in case of failing pm_runtime_get_sync(). There are two patches for the peak_usb driver. Dan Carpenter adds range checking in decode operations and Stephane Grosjean's patch fixes a timestamp wrapping problem. Stephane Grosjean's patch for th peak_canfd driver fixes echo management if loopback is on. The next three patches all target the mcp251xfd driver. The first one is by me and it increased the severity of CRC read error messages. The kernel test robot removes an unneeded semicolon and Tom Rix removes unneeded break in several switch-cases. The last 4 patches are by Joakim Zhang and target the flexcan driver, the first three fix ECC related device specific quirks for the LS1021A, LX2160A and the VF610 SoC. The last patch disable wakeup completely upon driver remove. * tag 'linux-can-fixes-for-5.10-20201103' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can: (27 commits) can: flexcan: flexcan_remove(): disable wakeup completely can: flexcan: add ECC initialization for VF610 can: flexcan: add ECC initialization for LX2160A can: flexcan: remove FLEXCAN_QUIRK_DISABLE_MECR quirk for LS1021A can: mcp251xfd: remove unneeded break can: mcp251xfd: mcp251xfd_regmap_nocrc_read(): fix semicolon.cocci warnings can: mcp251xfd: mcp251xfd_regmap_crc_read(): increase severity of CRC read error messages can: peak_canfd: pucan_handle_can_rx(): fix echo management when loopback is on can: peak_usb: peak_usb_get_ts_time(): fix timestamp wrapping can: peak_usb: add range checking in decode operations can: xilinx_can: handle failure cases of pm_runtime_get_sync can: ti_hecc: ti_hecc_probe(): add missed clk_disable_unprepare() in error path can: isotp: padlen(): make const array static, makes object smaller can: isotp: isotp_rcv_cf(): enable RX timeout handling in listen-only mode can: isotp: Explain PDU in CAN_ISOTP help text can: j1939: j1939_sk_bind(): return failure if netdev is down can: j1939: use backquotes for code samples can: j1939: swap addr and pgn in the send example can: j1939: fix syntax and spelling can: j1939: rename jacd tool ... ==================== Link: https://lore.kernel.org/r/<20201103220636.972106-1-mkl@pengutronix.de> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Since commit 530b5affc675 ("spi: fsl-dspi: fix use-after-free in remove path"), this driver causes a "NULL pointer dereference" in dspi_suspend/resume. This is because since this commit, the drivers private data point to "dspi" instead of "ctlr", the codes in suspend and resume func were not modified correspondly.
