commit 707293a5 upstream. Split phy_start_aneg into a wrapper which takes the PHY lock, and a helper doing the real work. This will be needed when phy_ethtook_ksettings_set takes the lock. Fixes: 2d55173e ("phy: add generic function to support ksetting support") Signed-off-by:

commit ace19b99 upstream. A hard hang is observed whenever the ethernet interface is brought down. If the PHY is stopped before the LPC core block is reset, the SoC will hang. Comparing lpc_eth_close() and lpc_eth_open() I re-arranged the ordering of the functions calls in lpc_eth_close() to reset the hardware before stopping the PHY.

commit 0c57eeec upstream. Drivers call netdev_set_num_tc() and then netdev_set_tc_queue() to set the queue count and offset for each TC. So the queue count and offset for the TCs may be zero for a short period after dev->num_tc has been set. If a TX packet is being transmitted at this time in the code path netdev_pick_tx() -> skb_tx_hash(), skb_tx_hash() may see nonzero dev->num_tc but zero qcount for the TC. The while loop that keeps looping while hash >= qcount will not end. Fix it by checking the TC's qcount to be nonzero before using it.

commit 6f68cd63 upstream. Syzbot reported ODEBUG warning in batadv_nc_mesh_free(). The problem was in wrong error handling in batadv_mesh_init(). Before this patch batadv_mesh_init() was calling batadv_mesh_free() in case of any batadv_*_init() calls failure. This approach may work well, when there is some kind of indicator, which can tell which parts of batadv are initialized; but there isn't any. All written above lead to cleaning up uninitialized fields. Even if we hide ODEBUG warning by initializing bat_priv->nc.work, syzbot was able to hit GPF in batadv_nc_purge_paths(), because hash pointer in still NULL. [1] To fix these bugs we can unwind batadv_*_init() calls one by one. It is good approach for 2 reasons: 1) It fixes bugs on error handling path 2) It improves the performance, since we won't call unneeded batadv_*_free() functions. So, this patch makes all batadv_*_init() clean up all allocated memory before returning with an error to no call correspoing batadv_*_free() and open-codes batadv_mesh_free() with proper order to avoid touching uninitialized fields.

commit 13bac861 upstream. sc_disable() after having disabled the send context wakes up any waiters by calling hfi1_qp_wakeup() while holding the waitlock for the sc. This is contrary to the model for all other calls to hfi1_qp_wakeup() where the waitlock is dropped and a local is used to drive calls to hfi1_qp_wakeup(). Fix by moving the sc->piowait into a local list and driving the wakeup calls from the list.

Find this issue when do quick SD card insert/remove stress test. During standard tuning prodedure, if remove SD card, USDHC standard tuning logic can't clear the internal flag execute_tuning_with_clr_buf. Next time when insert SD card, all data related commands can't get any data related interrupts, include data transfer complete interrupt, data timeout interrupt, data CRC interrupt, data end bit interrupt. Always trigger software timeout issue. Even reset the USDHC through bits in register SYS_CTRL (0x2C, bit28 reset tuning, bit26 reset data, bit 25 reset command, bit 24 reset all) can't recover this.

commit 4217d07b upstream. On Thundercomm TurboX CM2290, the eMMC OCR reports vdd = 23 (3.5 ~ 3.6 V), which is being treated as an invalid value by sdhci_set_power_noreg(). And thus eMMC is totally broken on the platform.

commit da353fac upstream. sk->sk_err appears to expect a positive value, a convention that ktls doesn't always follow and that leads to memory corruption in other code. For instance, [kworker] tls_encrypt_done(..., err=<negative error from crypto request>) tls_err_abort(.., err) sk->sk_err = err; [task] splice_from_pipe_feed ... tls_sw_do_sendpage if (sk->sk_err) { ret = -sk->sk_err; // ret is positive splice_from_pipe_feed (continued) ret = actor(...) // ret is still positive and interpreted as bytes // written, resulting in underflow of buf->len and // sd->len, leading to huge buf->offset and bogus // addresses computed in later calls to actor() Fix all tls_err_abort() callers to pass a negative error code consistently and centralize the error-prone sign flip there, throwing in a warning to catch future misuse and uninlining the function so it really does only warn once.

commit 10eff1f5 upstream. This reverts commit ab609f25. This patch is correct in the sense that we _should_ call device_put() in case of device_register() failure, but the problem in this code is more vast. We need to set bus->state to UNMDIOBUS_REGISTERED before calling device_register() to correctly release the device in mdiobus_free(). This patch prevents us from doing it, since in case of device_register() failure put_device() will be called 2 times and it will cause UAF or something else. Also, Reported-by: tag in revered commit was wrong, since syzbot reported different leak in same function. Link: https://lore.kernel.org/netdev/20210928092657.GI2048@kadam/ Acked-by:

commit 2195f206 upstream. During probing, the driver tries to get a list (mask) of supported command types in port100_get_command_type_mask() function. The value is u64 and 0 is treated as invalid mask (no commands supported). The function however returns also -ERRNO as u64 which will be interpret as valid command mask. Return 0 on every error case of port100_get_command_type_mask(), so the probing will stop.

commit a0023bb9 upstream. mv_init_host() propagates the value returned by mv_chip_id() which in turn gets propagated by mv_pci_init_one() and hits local_pci_probe(). During the process of driver probing, the probe function should return < 0 for failure, otherwise, the kernel will treat value > 0 as success. Since this is a bug rather than a recoverable runtime error we should use dev_alert() instead of dev_err(). Signed-off-by:

commit 6dba4bdf upstream. This reverts commit a49d784d . The updated binding was wrong / invalid and has been reverted. There isn't any upstream kernel DTS using it and Broadcom isn't known to use it neither. There is close to zero chance this will cause regression for anyone. Actually in-kernel bcm5301x.dtsi still uses the old good binding and so it's broken since the driver update. This revert fixes it. Signed-off-by:
