BugLink: https://bugs.launchpad.net/bugs/1878232 [ Upstream commit b87080ea ] After successfully running the IPC msgque test once, subsequent runs result in a test failure: $ sudo ./run_kselftest.sh TAP version 13 1..1 # selftests: ipc: msgque # Failed to get stats for IPC queue with id 0 # Failed to dump queue: -22 # Bail out! # # Pass 0 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0 not ok 1 selftests: ipc: msgque # exit=1 The dump_queue() function loops through the possible message queue index values using calls to msgctl(kern_id, MSG_STAT, ...) where kern_id represents the index value. The first time the test is ran, the initial index value of 0 is valid and the test is able to complete. The index value of 0 is not valid in subsequent test runs and the loop attempts to try index values of 1, 2, 3, and so on until a valid index value is found that corresponds to the message queue created earlier in the test. The msgctl() syscall returns -1 and sets errno to EINVAL when invalid index values are used. The test failure is caused by incorrectly comparing errno to -EINVAL when cycling through possible index values. Fix invalid test failures on subsequent runs of the msgque test by correctly comparing errno values to a non-negated EINVAL.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit c987ff0d upstream. Where a device driver has set a 64-bit DMA mask to indicate the absence of addressing limitations, we still need to ensure that we don't allocate IOVAs beyond the actual input size of the IOMMU. The reported aperture is the most reliable way we have of inferring that input address size, so use that to enforce a hard upper limit where available.

However if phy-handle was specified instead, an error message would complain about the lack of phy_id or fixed-link, and then jump past the of_get_phy_mode(). This would result in the PHY mode defaulting to MII, regardless of what the devicetree specified. Fixes: 9e42f715 ("drivers: net: cpsw: add phy-handle parsing") Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 commit deccd16f upstream. Commit 5ea94e76 ("phy: add phy_mac_interrupt()") to use with PHY_IGNORE_INTERRUPT added a cancel_work_sync() into phy_mac_interrupt() which is allowed to sleep, whereas phy_mac_interrupt() is expected to be callable from interrupt context. Now that we have fixed how the PHY state machine treats PHY_IGNORE_INTERRUPT with respect to state changes, we can just set the new link state, and queue the PHY state machine for execution so it is going to read the new link state. For that to work properly, we need to update phy_change() not to try to invoke any interrupt callbacks if we have configured the PHY device for PHY_IGNORE_INTERRUPT, because that PHY device and its driver are not required to implement those.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit d5c3d846 upstream. Commit 2c7b4921 ("phy: fix the use of PHY_IGNORE_INTERRUPT") changed a hunk in phy_state_machine() in the PHY_RUNNING case which was not needed. The change essentially makes the PHY library treat PHY devices with PHY_IGNORE_INTERRUPT to keep polling for the PHY device, even though the intent is not to do it. Fix this by reverting that specific hunk, which makes the PHY state machine wait for state changes, and stay in the PHY_RUNNING state for as long as needed.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 39d2adeb upstream. prior to this patch, at the beginning if we have two paths in one assoc, they may have the same params other than the last_time_heard, it will try the paths like this: 1st cycle try trans1 fail. then trans2 is selected.(cause it's last_time_heard is after trans1). 2nd cycle: try trans2 fail then trans2 is selected.(cause it's last_time_heard is after trans1). 3rd cycle: try trans2 fail then trans2 is selected.(cause it's last_time_heard is after trans1). .... trans1 will never have change to be selected, which is not what we expect. we should keeping round robin all the paths if they are just added at the beginning. So at first every tranport's last_time_heard should be initialized 0, so that we ensure they have the same value at the beginning, only by this, all the transports could get equal chance to be selected. Then for sctp_trans_elect_best, it should return the trans_next one when *trans == *trans_next, so that we can try next if it fails, but now it always return trans. so we can fix it by exchanging these two params when we calls sctp_trans_elect_tie().

BugLink: https://bugs.launchpad.net/bugs/1878232 commit d4aa908c upstream. Historically for Rockchip devices we've relied on the power-on default (or perhaps the firmware setting) to get the correct drive phase for dw_mmc devices. This worked OK for the most part, but: * Relying on the setting just "being right" is a bit fragile. * As soon as there is an instance where the power on default is wrong or where the firmware didn't configure this properly then we'll get a mysterious failure. In commit 7a03fe6f ("clk: rockchip: reset init state before mmc card initialization") we actually started setting this explicitly in the kernel, but that commit wasn't quite right and also wasn't quite enough. See <https://patchwork.kernel.org/patch/9085311/> for some details. Let's explicitly set this phase in dw_mmc. The comments inside this patch try to explain the situation quite throughly, but the high level overview of this is: Before this patch on rk3288 devices tested (after revert of the clock patch described above): * eMMC: 180 degrees * SDMMC/SDIO0/SDIO1: 90 degrees After this patch: * Use 90 degree phase offset usually. * Use 180 degree phase offset for MMC_DDR52, SDR104, HS200. That means we are _changing_ behavior for those devices in this way: * If we have HS200 eMMC or DDR52 eMMC, we'll run ID mode at 90 degrees (vs 180) but otherwise have no change. * For any non-HS200 / non-DDR52 eMMC devices we'll now _always_ run at 90 degrees (vs 180). It seems fairly unlikely that building modern hardware is using an eMMC that isn't using DDR52 or HS200, of course. * For SDR104 cards we'll now run with 180 degree phase offset (vs 90). It's expected that 90 degree phase offset would have worked OK, but this gives us extra margin. I have tested this by inserting my collection of uSD cards (mostly UHS, though a few not) into a veyron_minnie and confirmed that they still seem to enumerate properly. For a subset of them I tried putting a filesystem on them and also tried running mmc_test. Fixes: 7a03fe6f ("clk: rockchip: reset init state before mmc card initialization") Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 4715f81a upstream. This reverts commit 7a03fe6f ("clk: rockchip: reset init state before mmc card initialization"). Though not totally obvious from the commit message nor from the source code, that commit appears to be trying to reset the "_drv" MMC clocks to 90 degrees (note that the "_sample" MMC clocks have a shift of 0 so are not touched). The major problem here is that it doesn't properly reset things. The phase is a two bit field and the commit only touches one of the two bits. Thus the commit had the following affect: - phase 0 => phase 90 - phase 90 => phase 90 - phase 180 => phase 270 - phase 270 => phase 270 Things get even weirder if you happen to have a bootloader that was actually using delay elements (should be no reason to, but you never know), since those are additional bits that weren't touched by the original patch. This is unlikely to be what we actually want. Checking on rk3288-veyron devices, I can see that the bootloader leaves these clocks as: - emmc: phase 180 - sdmmc: phase 90 - sdio0: phase 90 Thus on rk3288-veyron devices the commit we're reverting had the effect of changing the eMMC clock to phase 270. This probably explains the scattered reports I've heard of eMMC devices not working on some veyron devices when using the upstream kernel. The original commit was presumably made because previously the kernel didn't touch the "_drv" phase at all and relied on whatever value was there when the kernel started. If someone was using a bootloader that touched the "_drv" phase then, indeed, we should have code in the kernel to fix that. ...and also, to get ideal timings, we should also have the kernel change the phase depending on the speed mode. In fact, that's the subject of a recent patch I posted at <https://patchwork.kernel.org/patch/9075141/>. Ideally, we should take both the patch posted to dw_mmc and this revert. Since those will likely go through different trees, here I describe behavior with the combos: 1. Just this revert: likely will fix rk3288-veyron eMMC on some devices + other cases; might break someone with a strange bootloader that sets the phase to 0 or one that uses delay elements (pretty unpredicable what would happen in that case). 2. Just dw_mmc patch: fixes everyone. Effectly the dw_mmc patch will totally override the broken patch and fix everything. 3. Both patches: fixes everyone. Once dw_mmc is initting properly then any defaults from the clock code doesn't mattery. Fixes: 7a03fe6f ("clk: rockchip: reset init state before mmc card initialization") Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 commit d9812780 upstream. The SD card specification allows cards to error out a SWITCH command where the requested function in a group is not supported. The spec provides for a set of capabilities which indicate which functions are supported. In the case of the power limit, requesting an unsupported power level via the SWITCH command fails, resulting in the power level remaining at the power-on default of 0.72W, even though the host and card may support higher powers levels. This has been seen with SanDisk 8GB cards, which support the default 0.72W and 1.44W (200mA and 400mA) in combination with an iMX6 host, supporting up to 2.88W (800mA). This currently causes us to try to set a power limit function value of '3' (2.88W) which the card errors out on, and thereby causes the power level to remain at 0.72W rather than the desired 1.44W. Arrange to limit the selected current limit by the capabilities reported by the card to avoid the SWITCH command failing. Select the highest current limit that the host and card combination support.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 918f4cbd upstream. After commit 52221610 ("mmc: sdhci: Improve external VDD regulator support"), for the VDD is supplied via external regulators, we ignore the code to convert a VDD voltage request into one of the standard SDHCI voltage levels, then program it in the SDHCI_POWER_CONTROL. This brings two issues: 1. SDHCI_QUIRK2_CARD_ON_NEEDS_BUS_ON quirk isn't handled properly any more. 2. What's more, once SDHCI_POWER_ON bit is set, some controllers such as the sdhci-pxav3 used in marvell berlin SoCs require the voltage levels programming in the SDHCI_POWER_CONTROL register, even the VDD is supplied by external regulator. So the host in marvell berlin SoCs still works fine after the commit. However, commit 3cbc6123 ("mmc: sdhci: Set SDHCI_POWER_ON with external vmmc") sets the SDHCI_POWER_ON bit, this would make the host in marvell berlin SoCs won't work any more with external vmmc. This patch restores the behavior when setting VDD through external regulator by moving the call of mmc_regulator_set_ocr() to the end of sdhci_set_power() function. After this patch, the sdcard on Marvell Berlin SoC boards work again. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 11476e9d upstream. At Connectathon 2016, we found that recent upstream Linux clients would occasionally send a LOCK operation with a zero stateid. This appeared to happen in close proximity to another thread returning a delegation before unlinking the same file while it remained open. Earlier, the client received a write delegation on this file and returned the open stateid. Now, as it is getting ready to unlink the file, it returns the write delegation. But there is still an open file descriptor on that file, so the client must OPEN the file again before it returns the delegation. Since commit 24311f88 ('NFSv4: Recovery of recalled read delegations is broken'), nfs_open_delegation_recall() clears the NFS_DELEGATED_STATE flag _before_ it sends the OPEN. This allows a racing LOCK on the same inode to be put on the wire before the OPEN operation has returned a valid open stateid. To eliminate this race, serialize delegation return with the acquisition of a file lock on the same file. Adopt the same approach as is used in the unlock path. This patch also eliminates a similar race seen when sending a LOCK operation at the same time as returning a delegation on the same file. Fixes: 24311f88 ('NFSv4: Recovery of recalled read ... ') Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 4b559ec0 upstream. It is possible that the station is connected to an AP with bandwidth of 80+80MHz or 160MHz. In such cases there is no need to perform an upgrade as the maximal supported bandwidth is 80MHz. In addition, when upgrading and setting center_freq1 and bandwidth to 80MHz also set center_freq2 to 0. Fixes: 0fabfaaf ("mac80211: upgrade BW of TDLS peers when possible" Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 59021c67 upstream. The previous approach simply ignored chandef restrictions when calculating the appropriate peer BW for a WIDER_BW peer. This could result in a regulatory violation if both peers indicated 80MHz support, but the regdomain forbade it. Change the approach to setting a WIDER_BW peer's BW. Don't exempt it from the chandef width at first. If during TDLS negotiation the chandef width is upgraded, update the peer's BW to match.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit b5884793 upstream. commit 1a6509d9 ("[IPSEC]: Add support for combined mode algorithms") introduced aead. The function attach_aead kmemdup()s the algorithm name during xfrm_state_construct(). However this memory is never freed. Implementation has since been slightly modified in commit ee5c2317 ("xfrm: Clone states properly on migration") without resolving this leak. This patch adds a kfree() call for the aead algorithm name. Fixes: 1a6509d9 ("[IPSEC]: Add support for combined mode algorithms") Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 2f30ea50 upstream. When we fail to attach the security context in xfrm_state_construct() we'll return 0 as error value which, in turn, will wrongly claim success to userland when, in fact, we won't be adding / updating the XFRM state. This is a regression introduced by commit fd21150a ("[XFRM] netlink: Inline attach_encap_tmpl(), attach_sec_ctx(), and attach_one_addr()"). Fix it by propagating the error returned by security_xfrm_state_alloc() in this case. Fixes: fd21150a ("[XFRM] netlink: Inline attach_encap_tmpl()...") Signed-off-by:
