2021-09-12PCI: Call Max Payload Size-related fixup quirks earlyMarek Behún
commit b8da302e2955fe4d41eb9d48199242674d77dbe0 upstream. pci_device_add() calls HEADER fixups after pci_configure_device(), which configures Max Payload Size. Convert MPS-related fixups to EARLY fixups so pci_configure_mps() takes them into account.

commit cbf286e8ef8337308c259ff5b9ce2e74d403be5a upstream. Removes static char buffer usage in the following decode functions: xhci_decode_trb() xhci_decode_ptortsc() Caller must provide a buffer to use. In tracing use __get_str() as recommended to pass buffer. Minor chanes are needed in xhci debugfs code as these functions are also used there.

2021-09-03Revert "floppy: reintroduce O_NDELAY fix"Denis Efremov
commit c7e9d0020361f4308a70cdfd6d5335e273eb8717 upstream. The patch breaks userspace implementations (e.g. fdutils) and introduces regressions in behaviour. Previously, it was possible to O_NDELAY open a floppy device with no media inserted or with write protected media without an error. Some userspace tools use this particular behavior for probing. It's not the first time when we revert this patch. Previous revert is in commit f2791e7eadf4 (Revert "floppy: refactor open() flags handling").

2021-09-03drm: Copy drm_wait_vblank to user before returningMark Yacoub
[ Upstream commit fa0b1ef5f7a694f48e00804a391245f3471aa155 ] [Why] Userspace should get back a copy of drm_wait_vblank that's been modified even when drm_wait_vblank_ioctl returns a failure. Rationale: drm_wait_vblank_ioctl modifies the request and expects the user to read it back. When the type is RELATIVE, it modifies it to ABSOLUTE and updates the sequence to become current_vblank_count + sequence (which was RELATIVE), but now it became ABSOLUTE. drmWaitVBlank (in libdrm) expects this to be the case as it modifies the request to be Absolute so it expects the sequence to would have been updated. The change is in compat_drm_wait_vblank, which is called by drm_compat_ioctl. This change of copying the data back regardless of the return number makes it en par with drm_ioctl, which always copies the data before returning.

2021-09-03vringh: Use wiov->used to check for read/write desc orderNeeraj Upadhyay
[ Upstream commit e74cfa91f42c50f7f649b0eca46aa049754ccdbd ] As __vringh_iov() traverses a descriptor chain, it populates each descriptor entry into either read or write vring iov and increments that iov's ->used member. So, as we iterate over a descriptor chain, at any point, (riov/wriov)->used value gives the number of descriptor enteries available, which are to be read or written by the device. As all read iovs must precede the write iovs, wiov->used should be zero when we are traversing a read descriptor. Current code checks for wiov->i, to figure out whether any previous entry in the current descriptor chain was a write descriptor. However, iov->i is only incremented, when these vring iovs are consumed, at a later point, and remain 0 in __vringh_iov(). So, correct the check for read and write descriptor order, to use wiov->used.

Reader and writer are accessing it without any synchronization. This may lead to a compiler optimization which may result to optimize reading vq->broken only once. Hence, force reading vq->broken on each invocation of virtqueue_is_broken() and also force writing it so that such update is visible to the readers.

2021-09-03net: hns3: fix get wrong pfc_en when query PFC configurationGuangbin Huang
[ Upstream commit 8c1671e0d13d4a0ba4fb3a0da932bf3736d7ff73 ] Currently, when query PFC configuration by dcbtool, driver will return PFC enable status based on TC. As all priorities are mapped to TC0 by default, if TC0 is enabled, then all priorities mapped to TC0 will be shown as enabled status when query PFC setting, even though some priorities have never been set. for example: $ dcb pfc show dev eth0 pfc-cap 4 macsec-bypass off delay 0 prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off $ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on $ dcb pfc show dev eth0 pfc-cap 4 macsec-bypass off delay 0 prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on To fix this problem, just returns user's PFC config parameter saved in driver.

If it fails, the function __sdma_txclean() is called: __sdma_txclean(dd, tx); However, in the function __sdma_txclean(), tx-descp is dereferenced if tx->num_desc is not zero: sdma_unmap_desc(dd, &tx->descp[0]); To fix this possible null-pointer dereference, assign the return value of kmalloc_array() to a local variable descp, and then assign it to tx->descp if it is not NULL.

2021-09-03usb: dwc3: gadget: Stop EP0 transfers during pullup disableWesley Cheng
commit 4a1e25c0a029b97ea4a3d423a6392bfacc3b2e39 upstream. During a USB cable disconnect, or soft disconnect scenario, a pending SETUP transaction may not be completed, leading to the following error: dwc3 a600000.dwc3: timed out waiting for SETUP phase If this occurs, then the entire pullup disable routine is skipped and proper cleanup and halting of the controller does not complete. Instead of returning an error (which is ignored from the UDC perspective), allow the pullup disable routine to continue, which will also handle disabling of EP0/1. This will end any active transfers as well. Ensure to clear any delayed_status also, as the timeout could happen within the STATUS stage.

commit 51f1954ad853d01ba4dc2b35dee14d8490ee05a1 upstream. We can't depend on the TRB's HWO bit to determine if the TRB ring is "full". A TRB is only available when the driver had processed it, not when the controller consumed and relinquished the TRB's ownership to the driver. Otherwise, the driver may overwrite unprocessed TRBs. This can happen when many transfer events accumulate and the system is slow to process them and/or when there are too many small requests. If a request is in the started_list, that means there is one or more unprocessed TRBs remained. Check this instead of the TRB's HWO bit whether the TRB ring is full.

These devices do not appear to send a zero-length packet when the transfer size is a multiple of the bulk-endpoint max-packet size. This means that incoming data may not be processed by the driver until a short packet is received or the receive buffer is full.

2021-08-26PCI: Increase D3 delay for AMD Renoir/Cezanne XHCIMarcin Bachry
[ Upstream commit e0bff43220925b7e527f9d3bc9f5c624177c959e ] The Renoir XHCI controller apparently doesn't resume reliably with the standard D3hot-to-D0 delay. Increase it to 20ms. [Alex: I talked to the AMD USB hardware team and the AMD Windows team and they are not aware of any HW errata or specific issues. The HW works fine in Windows. I was told Windows uses a rather generous default delay of 100ms for PCI state transitions.] Link: https://lore.kernel.org/r/20210722025858.220064-1-alexander.deucher@amd.com Signed-off-by: Marcin Bachry <hegel666@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Cc: stable@vger.kernel.org Cc: Mario Limonciello <mario.limonciello@amd.com> Cc: Prike Liang <prike.liang@amd.com> Cc: Shyam Sundar S K <shyam-sundar.s-k@amd.com> Signed-off-by: Sasha Levin <sashal@kernel.org>

2021-08-26ipack: tpci200: fix many double free issues in tpci200_pci_probeDongliang Mu
[ Upstream commit 57a1681095f912239c7fb4d66683ab0425973838 ] The function tpci200_register called by tpci200_install and tpci200_unregister called by tpci200_uninstall are in pair. However, tpci200_unregister has some cleanup operations not in the tpci200_register. So the error handling code of tpci200_pci_probe has many different double free issues. Fix this problem by moving those cleanup operations out of tpci200_unregister, into tpci200_pci_remove and reverting the previous commit 9272e5d0028d ("ipack/carriers/tpci200: Fix a double free in tpci200_pci_probe").

[ Upstream commit a263c1ff6abe0e66712f40d595bbddc7a35907f8 ] In some usecases transaction ids are dynamically allocated inside the controller driver after sending the messages which have generic acknowledge responses. So check for this before refcounting pm_runtime. Without this we would end up imbalancing runtime pm count by doing pm_runtime_put() in both slim_do_transfer() and slim_msg_response() for a single pm_runtime_get() in slim_do_transfer() Fixes: d3062a210930 ("slimbus: messaging: add slim_alloc/free_txn_tid()") Cc: <stable@vger.kernel.org> Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Link: https://lore.kernel.org/r/20210809082428.11236-3-srinivas.kandagatla@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sasha Levin <sashal@kernel.org>

So Start the transaction ids from 1 instead of zero so that we could differentiate between a valid tid and invalid tids This is useful in cases where controller would add a tid for controller specific transfers.
