System hang also can be reproduced easily during system suspend/resume stess test when mount NFS on i.MX8MP EVK board. In stmmac driver, eee feature is combined to phylink framework. When do system suspend, phylink_stop() would queue delayed work, it invokes stmmac_mac_link_down(), where to deactivate eee_ctrl_timer synchronizly. In above commit, try to fix issue by deactivating eee_ctrl_timer obviously, but it is not enough. Looking into eee_ctrl_timer expire callback stmmac_eee_ctrl_timer(), it could enable hareware eee mode again. What is unexpected is that LPI interrupt (MAC_Interrupt_Enable.LPIEN bit) is always asserted. This interrupt has chance to be issued when LPI state entry/exit from the MAC, and at that time, clock could have been already disabled. The result is that system hang when driver try to touch register from interrupt handler. The reason why above commit can fix system hang issue in stmmac_release() is that, deactivate eee_ctrl_timer not just after napi disabled, further after irq freed. In conclusion, hardware would generate LPI interrupt when clock has been disabled during suspend or resume, since hardware is in eee mode and LPI interrupt enabled. Interrupts from MAC, MTL and DMA level are enabled and never been disabled when system suspend, so postpone clocks management from suspend stage to noirq suspend stage should be more safe.

This causes some oddities around workers switching type and even hashed work vs regular work on the same bounded list. Just separate them out cleanly, similarly to how we already do accounting of what is running.

FAILED: patch "[PATCH] x86/mm: Fix kern_addr_valid() to cope with existing but not" failed to apply to 4.9-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.9-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 34b1999da935a33be6239226bfa6cd4f704c5c88 Mon Sep 17 00:00:00 2001 From: Mike Rapoport <rppt(a)linux.ibm.com> Date: Thu, 19 Aug 2021 16:27:17 +0300 Subject: [PATCH] x86/mm: Fix kern_addr_valid() to cope with existing but not present entries Jiri Olsa reported a fault when running: # cat /proc/kallsyms | grep ksys_read ffffffff8136d580 T ksys_read # objdump -d --start-address=0xffffffff8136d580 --stop-address=0xffffffff8136d590 /proc/kcore /proc/kcore: file format elf64-x86-64 Segmentation fault general protection fault, probably for non-canonical address 0xf887ffcbff000: 0000 [#1] SMP PTI CPU: 12 PID: 1079 Comm: objdump Not tainted 5.14.0-rc5qemu+ #508 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.14.0-4.fc34 04/01/2014 RIP: 0010:kern_addr_valid Call Trace: read_kcore ? rcu_read_lock_sched_held ? rcu_read_lock_sched_held ? rcu_read_lock_sched_held ? trace_hardirqs_on ? rcu_read_lock_sched_held ? lock_acquire ? lock_acquire ? rcu_read_lock_sched_held ? lock_acquire ? rcu_read_lock_sched_held ? rcu_read_lock_sched_held ? rcu_read_lock_sched_held ? lock_release ? _raw_spin_unlock ? __handle_mm_fault ? rcu_read_lock_sched_held ? lock_acquire ? rcu_read_lock_sched_held ? lock_release proc_reg_read ? vfs_read vfs_read ksys_read do_syscall_64 entry_SYSCALL_64_after_hwframe The fault happens because kern_addr_valid() dereferences existent but not present PMD in the high kernel mappings. Such PMDs are created when free_kernel_image_pages() frees regions larger than 2Mb. In this case, a part of the freed memory is mapped with PMDs and the set_memory_np_noalias() -> ... -> __change_page_attr() sequence will mark the PMD as not present rather than wipe it completely. Have kern_addr_valid() check whether higher level page table entries are present before trying to dereference them to fix this issue and to avoid similar issues in the future. Stable backporting note: ------------------------ Note that the stable marking is for all active stable branches because there could be cases where pagetable entries exist but are not valid - see 9a14aefc1d28 ("x86: cpa, fix lookup_address"), for example. So make sure to be on the safe side here and use pXY_present() accessors rather than pXY_none() which could #GP when accessing pages in the direct map.

[PATCH net] nexthop: Fix division by zero while replacing a resilient group

by Ido Schimmel

From: Ido Schimmel <idosch(a)nvidia.com> The resilient nexthop group torture tests in fib_nexthop.sh exposed a possible division by zero while replacing a resilient group [1]. The division by zero occurs when the data path sees a resilient nexthop group with zero buckets. The tests replace a resilient nexthop group in a loop while traffic is forwarded through it. The tests do not specify the number of buckets while performing the replacement, resulting in the kernel allocating a stub resilient table (i.e, 'struct nh_res_table') with zero buckets. This table should never be visible to the data path, but the old nexthop group (i.e., 'oldg') might still be used by the data path when the stub table is assigned to it. Fix this by only assigning the stub table to the old nexthop group after making sure the group is no longer used by the data path. Tested with fib_nexthops.sh: Tests passed: 222 Tests failed: 0 [1] divide error: 0000 [#1] PREEMPT SMP KASAN CPU: 0 PID: 1850 Comm: ping Not tainted 5.14.0-custom-10271-ga86eb53057fe #1107 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-4.fc34 04/01/2014 RIP: 0010:nexthop_select_path+0x2d2/0x1a80 [...] Call Trace: fib_select_multipath+0x79b/0x1530 fib_select_path+0x8fb/0x1c10 ip_route_output_key_hash_rcu+0x1198/0x2da0 ip_route_output_key_hash+0x190/0x340 ip_route_output_flow+0x21/0x120 raw_sendmsg+0x91d/0x2e10 inet_sendmsg+0x9e/0xe0 __sys_sendto+0x23d/0x360 __x64_sys_sendto+0xe1/0x1b0 do_syscall_64+0x35/0x80 entry_SYSCALL_64_after_hwframe+0x44/0xae Cc: stable(a)vger.kernel.org Fixes: 283a72a5599e ("nexthop: Add implementation of resilient next-hop groups") Signed-off-by: Ido Schimmel <idosch(a)nvidia.com> Reviewed-by: Petr Machata <petrm(a)nvidia.com> --- net/ipv4/nexthop.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/net/ipv4/nexthop.c b/net/ipv4/nexthop.c index 75ca4b6e484f..0e75fd3e57b4 100644 --- a/net/ipv4/nexthop.c +++ b/net/ipv4/nexthop.c @@ -1982,6 +1982,8 @@ static int replace_nexthop_grp(struct net *net, struct nexthop *old, rcu_assign_pointer(old->nh_grp, newg); if (newg->resilient) { + /* Make sure concurrent readers are not using 'oldg' anymore. */ + synchronize_net(); rcu_assign_pointer(oldg->res_table, tmp_table); rcu_assign_pointer(oldg->spare->res_table, tmp_table); } -- 2.31.1

net: qrtr: revert check in qrtr_endpoint_post()

by Steev Klimaszewski

net: qrtr: revert check in qrtr_endpoint_post() d2cabd2dc8da78faf9b690ea521d03776686c9fe <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…> Applied to 5.14 if possible - Have tested it locally, and it applies without any issues. The reason for the request is that 5.14.4 had net: qrtr: make checks in qrtr_endpoint_post() stricter applied, and this breaks qrtr on at least my Lenovo Yoga C630 which means that it no longer has working wifi without the patch above. I thought it had already been requested, but there have been 3 point releases of 5.14 since the break and it doesn't look like it's queued up anywhere. Apologies if I did this incorrectly, I'm trying to follow Option 2 in stable-kernel-rules since it doesn't appear to have been CC'd on the initial patch.

Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱. Targeted tests -------------- Test runs for patches always include a set of base tests, plus some tests chosen based on the file paths modified by the patch. The latter are called "targeted tests". If no targeted tests are run, that means no patch-specific tests are available. Please, consider contributing a targeted test for related patches to increase test coverage. See https://docs.engineering.redhat.com/x/_wEZB for more details.

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱. Targeted tests -------------- Test runs for patches always include a set of base tests, plus some tests chosen based on the file paths modified by the patch. The latter are called "targeted tests". If no targeted tests are run, that means no patch-specific tests are available. Please, consider contributing a targeted test for related patches to increase test coverage.

Be a bit nicer and allow normal retry IFF the file does support async behavior.
