[PATCH] drm/etnaviv: fix perfmon domain interation

by Christian Gmeiner

The GC860 has one GPU device which has a 2d and 3d core. In this case we want to expose perfmon information for both cores. The driver has one array which contains all possible perfmon domains with some meta data - doms_meta. Here we can see that for the GC860 two elements of that array are relevant: doms_3d: is at index 0 in the doms_meta array with 8 perfmon domains doms_2d: is at index 1 in the doms_meta array with 1 perfmon domain The userspace driver wants to get a list of all perfmon domains and their perfmon signals. This is done by iterating over all domains and their signals. If the userspace driver wants to access the domain with id 8 the kernel driver fails and returns invalid data from doms_3d with and invalid offset. This results in: Unable to handle kernel paging request at virtual address 00000000 On such a device it is not possible to use the userspace driver at all. The fix for this off-by-one error is quite simple.

[PATCH v2 for 4.4, 4.9] spi: spi-dw: Add lock protect dw_spi rx/tx to prevent concurrent calls

by Nobuhiro Iwamatsu

From: "wuxu.wu" <wuxu.wu(a)huawei.com> commit 19b61392c5a852b4e8a0bf35aecb969983c5932d upstream. dw_spi_irq() and dw_spi_transfer_one concurrent calls. I find a panic in dw_writer(): txw = *(u8 *)(dws->tx), when dw->tx==null, dw->len==4, and dw->tx_end==1. When tpm driver's message overtime dw_spi_irq() and dw_spi_transfer_one may concurrent visit dw_spi, so I think dw_spi structure lack of protection. Otherwise dw_spi_transfer_one set dw rx/tx buffer and then open irq, store dw rx/tx instructions and other cores handle irq load dw rx/tx instructions may out of order. [ 1025.321302] Call trace: ...

Re: stable/linux-4.4.y bisection: baseline.login on at91-sama5d4_xplained

by Guillaume Tucker

Please see the bisection report below about a boot failure. Reports aren't automatically sent to the public while we're trialing new bisection features on kernelci.org but this one looks valid. It appears to be due to the fact that the network interface is failing to get brought up: [ 114.385000] Waiting up to 10 more seconds for network. [ 124.355000] Sending DHCP requests ...# ..# .# timed out! [ 212.355000] IP-Config: Reopening network devices... [ 212.365000] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready # I guess the board would boot fine without network if it didn't have ip=dhcp in the command line, so it's not strictly a kernel boot failure but still an ethernet issue. There wasn't any failure reported by kernelci on linux-4.9.y so maybe this patch was applied by mistake on linux-4.4.y but I haven't investigated enough to prove this.

[PATCH] usb: core: hub: limit HUB_QUIRK_DISABLE_AUTOSUSPEND to USB5534B

by Eugeniu Rosca

On Tue, May 12, 2020 at 09:36:07PM +0800, Kai-Heng Feng wrote [1]: > This patch prevents my Raven Ridge xHCI from getting runtime suspend. The problem described in v5.6 commit 1208f9e1d758c9 ("USB: hub: Fix the broken detection of USB3 device in SMSC hub") applies solely to the USB5534B hub [2] present on the Kingfisher Infotainment Carrier Board, manufactured by Shimafuji Electric Inc [3]. Despite that, the aforementioned commit applied the quirk to _all_ hubs carrying vendor ID 0x424 (i.e. SMSC), of which there are more [4] than initially expected. Consequently, the quirk is now enabled on platforms carrying SMSC/Microchip hub models which potentially don't exhibit the original issue. To avoid reports like [1], further limit the quirk's scope to USB5534B [2], by employing both Vendor and Product ID checks. Tested on H3ULCB + Kingfisher rev. M05.

[PATCH v2] scsi: target: put lun_ref at end of tmr processing

by Bodo Stroesser

Testing with Loopback I found, that after a Loopback LUN has executed a TMR, I can no longer unlink the LUN. The rm command hangs in transport_clear_lun_ref() at wait_for_completion(&lun->lun_shutdown_comp) The reason is, that transport_lun_remove_cmd() is not called at the end of target_tmr_work(). It seems, that in other fabrics this call happens implicitly when the fabric drivers call transport_generic_free_cmd() during their ->queue_tm_rsp(). Unfortunately Loopback seems to not comply to the common way of calling transport_generic_free_cmd() from ->queue_*(). Instead it calls transport_generic_free_cmd() from its ->check_stop_free() only. But the ->check_stop_free() is called by transport_cmd_check_stop_to_fabric() after it has reset the se_cmd->se_lun pointer. Therefore the following transport_generic_free_cmd() skips the transport_lun_remove_cmd(). So this patch re-adds the transport_lun_remove_cmd() at the end of target_tmr_work(), which was removed during commit 2c9fa49e100f962af988f1c0529231bf14905cda "scsi: target/core: Make ABORT and LUN RESET handling synchronous" For fabrics using transport_generic_free_cmd() in the usual way the double call to transport_lun_remove_cmd() doesn't harm, as transport_lun_remove_cmd() checks for this situation and does not release lun_ref twice.

[PATCH for 4.4, 4.9] spi: spi-dw: Add lock protect dw_spi rx/tx to prevent concurrent calls

by Nobuhiro Iwamatsu

From: "wuxu.wu" <wuxu.wu(a)huawei.com> commit 19b61392c5a852b4e8a0bf35aecb969983c5932d upstream. dw_spi_irq() and dw_spi_transfer_one concurrent calls. I find a panic in dw_writer(): txw = *(u8 *)(dws->tx), when dw->tx==null, dw->len==4, and dw->tx_end==1. When tpm driver's message overtime dw_spi_irq() and dw_spi_transfer_one may concurrent visit dw_spi, so I think dw_spi structure lack of protection. Otherwise dw_spi_transfer_one set dw rx/tx buffer and then open irq, store dw rx/tx instructions and other cores handle irq load dw rx/tx instructions may out of order. [ 1025.321302] Call trace: ...
