commit ef54cf0c upstream. usbip host binds to devices attached to vhci_hcd on the same server when user does attach over localhost or specifies the server as the remote. usbip attach -r localhost -b busid or usbip attach -r servername (or server IP) Unbind followed by bind works, however device is left in a bad state with accesses via the attached busid result in errors and system hangs during shutdown. Fix it to check and bail out if the device is already attached to vhci_hcd. Signed-off-by:

commit c7b8f778 upstream. According to drivers/usb/serial/io_edgeport.c, the driver may sleep under a spinlock. The function call path is: edge_bulk_in_callback (acquire the spinlock) process_rcvd_data process_rcvd_status change_port_settings send_iosp_ext_cmd write_cmd_usb usb_kill_urb --> may sleep To fix it, the redundant usb_kill_urb() is removed from the error path after usb_submit_urb() fails. This possible bug is found by my static analysis tool (DSAC) and checked by my code review. Signed-off-by:

commit 9b046013 upstream. The logic of the original commit 4d99b258 ("staging: lustre: avoid intensive reconnecting for ko2iblnd") was assumed conditional free of struct kib_conn if the second argument free_conn in function kiblnd_destroy_conn(struct kib_conn *conn, bool free_conn) is true. But this hunk of code was dropped from original commit. As result the logic works wrong and current code use struct kib_conn after free. > drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c > 3317 kiblnd_destroy_conn(conn, !peer); > ^^^^ Freed always (but should be conditionally) > 3318 > 3319 spin_lock_irqsave(lock, flags); > 3320 if (!peer) > 3321 continue; > 3322 > 3323 conn->ibc_peer = peer; > ^^^^^^^^^^^^^^ Use after free > 3324 if (peer->ibp_reconnected < KIB_RECONN_HIGH_RACE) > 3325 list_add_tail(&conn->ibc_list, > ^^^^^^^^^^^^^^ Use after free > 3326 &kiblnd_data.kib_reconn_list); > 3327 else > 3328 list_add_tail(&conn->ibc_list, > ^^^^^^^^^^^^^^ Use after free > 3329 &kiblnd_data.kib_reconn_wait); To avoid confusion this fix moved the freeing a struct kib_conn outside of the function kiblnd_destroy_conn() and free as it was intended in original commit.

[ Upstream commit ce9caf2f ] We were calling enable_irq on bind, where it was already enabled previously by the IRQ helper. Additionally, dev->irq is not set correctly until after postinstall and so was always zero here, triggering a warning in 4.15. Fix both by moving the enable to the power management resume path, where we know there was a previous disable invocation during suspend.

[ Upstream commit b77992d2 ] When not associated with an AP, wifi device drivers should respond to the SIOCGIWESSID ioctl with a zero-length string for the SSID, which is the behavior expected by dhcpcd. Currently, this driver returns an error code (-1) from the ioctl call, which causes dhcpcd to assume that the device is not a wireless interface and therefore it fails to work correctly with it thereafter.

[ Upstream commit e4717292 ] As part of the scsi EH path, aacraid performs a reinitialization of the adapter, which encompass freeing resources and IRQs, NULLifying lots of pointers, and then initialize it all over again. We've identified a problem during the free IRQ portion of this path if CONFIG_DEBUG_SHIRQ is enabled on kernel config file. Happens that, in case this flag was set, right after free_irq() effectively clears the interrupt, it checks if it was requested as IRQF_SHARED. In positive case, it performs another call to the IRQ handler on driver. Problem is: since aacraid currently free some resources *before* freeing the IRQ, once free_irq() path calls the handler again (due to CONFIG_DEBUG_SHIRQ), aacraid crashes due to NULL pointer dereference with the following trace: aac_src_intr_message+0xf8/0x740 [aacraid] __free_irq+0x33c/0x4a0 free_irq+0x78/0xb0 aac_free_irq+0x13c/0x150 [aacraid] aac_reset_adapter+0x2e8/0x970 [aacraid] aac_eh_reset+0x3a8/0x5d0 [aacraid] scsi_try_host_reset+0x74/0x180 scsi_eh_ready_devs+0xc70/0x1510 scsi_error_handler+0x624/0xa20 This patch prevents the crash by changing the order of the deinitialization in this path of aacraid: first we clear the IRQ, then we free other resources. No functional change intended. Signed-off-by:

[ Upstream commit 373b0589 ] Once the inode item writeback errors is already fixed, it's time to fix the same problem in dquot code. Although there were no reports of users hitting this bug in dquot code (at least none I've seen), the bug is there and I was already planning to fix it when the correct approach to fix the inodes part was decided. This patch aims to fix the same problem in dquot code, regarding failed buffers being unable to be resubmitted once they are flush locked.

[ Upstream commit 81833de1 ] restart_grace() uses hardcoded init_net. It can cause to "list_add double add" in following scenario: 1) nfsd and lockd was started in several net namespaces 2) nfsd in init_net was stopped (lockd was not stopped because it have users from another net namespaces) 3) lockd got signal, called restart_grace() -> set_grace_period() and enabled lock_manager in hardcoded init_net. 4) nfsd in init_net is started again, its lockd_up() calls set_grace_period() and tries to add lock_manager into init_net 2nd time. Jeff Layton suggest: "Make it safe to call locks_start_grace multiple times on the same lock_manager. If it's already on the global grace_list, then don't try to add it again. (But we don't intentionally add twice, so for now we WARN about that case.) With this change, we also need to ensure that the nfsd4 lock manager initializes the list before we call locks_start_grace. While we're at it, move the rest of the nfsd_net initialization into nfs4_state_create_net. I see no reason to have it spread over two functions like it is today." Suggested patch was updated to generate warning in described situation. Suggested-by:
