[ Upstream commit 2eb8d6d2 ] The check for !md doens't really work for ip_tunnel_info_opts(info) which only does info + 1. Also to avoid out-of-bounds access on info, it should ensure options_len is not less than erspan_metadata in both erspan_xmit() and ip6erspan_tunnel_xmit().

The problem is we had a request in the queue at the same time, so we completed the request twice. This can actually happen in a lot of cases, we fail to get a ref on our config, we only have one connection and just error out the command, etc. Fix this by checking cmd->status in nbd_read_stat. We only change this under the cmd->lock, so we are safe to check this here and see if we've already error'ed this command out, which would indicate that we've completed it as well. Reviewed-by:

[ Upstream commit de6346ec ] We already do this for the most part, except in timeout and clear_req. For the timeout case we take the lock after we grab a ref on the config, but that isn't really necessary because we're safe to touch the cmd at this point, so just move the order around. For the clear_req cause this is initiated by the user, so again is safe. Reviewed-by:

[ Upstream commit d46b0da7 ] There's a deadlock that is possible and can easily be seen with a test where multiple readers open/read/close of the same file and a disruption occurs causing reconnect. The deadlock is due a reader thread inside cifs_strict_readv calling down_read and obtaining lock_sem, and then after reconnect inside cifs_reopen_file calling down_read a second time. If in between the two down_read calls, a down_write comes from another process, deadlock occurs. CPU0 CPU1 ---- ---- cifs_strict_readv() down_read(&cifsi->lock_sem); _cifsFileInfo_put OR cifs_new_fileinfo down_write(&cifsi->lock_sem); cifs_reopen_file() down_read(&cifsi->lock_sem); Fix the above by changing all down_write(lock_sem) calls to down_write_trylock(lock_sem)/msleep() loop, which in turn makes the second down_read call benign since it will never block behind the writer while holding lock_sem.

[ Upstream commit 6d6b0d0d ] When in slave mode, an arbitration loss (ARLO) may be detected before the slave had a chance to detect the stop condition (STOPF in ISR). This is seen when two master + slave adapters switch their roles. It provokes the i2c bus to be stuck, busy as SCL line is stretched. - the I2C_SLAVE_STOP event is never generated due to STOPF flag is set but don't generate an irq (race with ARLO irq, STOPIE is masked). STOPF flag remains set until next master xfer (e.g. when STOPIE irq get unmasked). In this case, completion is generated too early: immediately upon new transfer request (then it doesn't send all data). - Some data get stuck in TXDR register. As a consequence, the controller stretches the SCL line: the bus gets busy until a future master transfer triggers the bus busy / recovery mechanism (this can take time... and may never happen at all) So choice is to let the STOPF being detected by the slave isr handler, to properly handle this stop condition. E.g. don't mask IRQs in error handler, when the slave is running. Fixes: 60d609f3 ("i2c: i2c-stm32f7: Add slave support") Signed-off-by:

[ Upstream commit 84243125 ] On a system without Single VMOVP support (say GITS_TYPER.VMOVP == 0), we will map vPEs only on ITSs that will actually control interrupts for the given VM. And when moving a vPE, the VMOVP command will be issued only for those ITSs. But when issuing VMOVPs we seemed fail to present the exact ITSList to ITSs who are actually included in the synchronization operation. The its_list_map we're currently using includes all ITSs in the system, even though some of them don't have the corresponding vPE mapping at all. Introduce get_its_list() to get the per-VM its_list_map, to indicate which ITSs have vPE mappings for the given VM, and use this map as the expected ITSList when building VMOVP. This is hopefully a performance gain not to do some synchronization with those unsuspecting ITSs. And initialize the whole command descriptor to zero at beginning, since the seq_num and its_list should be RES0 when GITS_TYPER.VMOVP == 1. Signed-off-by:

[ Upstream commit 2ecb2879 ] r0-r3 & r12 registers are saved & restored, before & after svc respectively. Intention was to preserve those registers across thread to handler mode switch. On v7-M, hardware saves the register context upon exception in AAPCS complaint way. Restoring r0-r3 & r12 is done from stack location where hardware saves it, not from the location on stack where these registers were saved. To clarify, on stm32f429 discovery board: 1. before svc, sp - 0x90009ff8 2. r0-r3,r12 saved to 0x90009ff8 - 0x9000a00b 3. upon svc, h/w decrements sp by 32 & pushes registers onto stack 4. after svc, sp - 0x90009fd8 5. r0-r3,r12 restored from 0x90009fd8 - 0x90009feb Above means r0-r3,r12 is not restored from the location where they are saved, but since hardware pushes the registers onto stack, the registers are restored correctly. Note that during register saving to stack (step 2), it goes past 0x9000a000. And it seems, based on objdump, there are global symbols residing there, and it perhaps can cause issues on a non-XIP Kernel (on XIP, data section is setup later). Based on the analysis above, manually saving registers onto stack is at best no-op and at worst can cause data section corruption. Hence remove storing of registers onto stack before svc.

[ Upstream commit 25113667 ] Depending on kernel and bootloader configuration, it's possible that Realtek ethernet PHY isn't powered on properly. According to the datasheet, it needs 30ms to power up and then some more time before it can be used. Fix that by adding 100ms ramp delay to regulator responsible for powering PHY.

[ Upstream commit ca234719 ] In case of WM1811 device there are currently being registered controls referring to registers not existing on that device. It has been noticed when getting values of "AIF1ADC2 Volume", "AIF1DAC2 Volume" controls was failing during ALSA state restoring at boot time: "amixer: Mixer hw:0 load error: Device or resource busy" Reading some registers through I2C was failing with EBUSY error and indeed these registers were not available according to the datasheet. To fix this controls not available on WM1811 are moved to a separate array and registered only for WM8994 and WM8958. There are some further differences between WM8994 and WM1811, e.g. registers 603h, 604h, 605h, which are not covered in this patch. Acked-by:

[ Upstream commit 131cb121 ] Currently the regulator-suspend-min/max-microvolt must be within the root regulator node but the dt-bindings specifies it as subnode properties for the regulator-state-[mem/disk/standby] node. The only DT using this bindings currently is the at91-sama5d2_xplained.dts and this DT uses it correctly. I don't know if it isn't tested but it can't work without this fix.

[ Upstream commit 29be86d7 ] The gcc -fcf-protection=branch option is not compatible with -mindirect-branch=thunk-extern. The latter is used when CONFIG_RETPOLINE is selected, and this will fail to build with a gcc which has -fcf-protection=branch enabled by default. Adding -fcf-protection=none when building with retpoline enabled prevents such build failures. Signed-off-by:
