[ Upstream commit ea22eee4 ] Before this patch, a simple typo accidentally added \n to the jid= string for lock_nolock mounts. This made it impossible to mount a gfs2 file system with a journal other than journal0. Thus: mount -tgfs2 -o hostdata="jid=1" <device> <mount pt> Resulted in: mount: wrong fs type, bad option, bad superblock on <device> In most cases this is not a problem. However, for debugging and testing purposes we sometimes want to test the integrity of other journals. This patch removes the unnecessary \n and thus allows lock_nolock users to specify an alternate journal. Signed-off-by:

[ Upstream commit 6bd140e1 ] Working on the OpenRISC glibc port I found that sometimes clone was working strange. That the tls data argument sent in r7 was always wrong. Further investigation revealed that the arguments were getting clobbered in the entry code. This patch removes the code that writes to the argument registers. This was likely due to some old code hanging around. This patch fixes this up for clone and fork. This fork clobber is harmless but also useless so remove. Signed-off-by:

[ Upstream commit aa8ba13c ] kobject_init_and_add() takes reference even when it fails. If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object. Thus, replace kfree() by kobject_put() to fix this issue. Previous commit "b8eb7183" fixed a similar problem. Fixes: 7b96953b ("vfio: Mediated device Core driver") Signed-off-by:

[ Upstream commit 36124fb1 ] fsl_asrc_dma_hw_params() invokes dma_request_channel() or fsl_asrc_get_dma_channel(), which returns a reference of the specified dma_chan object to "pair->dma_chan[dir]" with increased refcnt. The reference counting issue happens in one exception handling path of fsl_asrc_dma_hw_params(). When config DMA channel failed for Back-End, the function forgets to decrease the refcnt increased by dma_request_channel() or fsl_asrc_get_dma_channel(), causing a refcnt leak. Fix this issue by calling dma_release_channel() when config DMA channel failed. Signed-off-by:

[ Upstream commit 118917d6 ] Fix off-by-one issues in 'rpc_ntop6': - 'snprintf' returns the number of characters which would have been written if enough space had been available, excluding the terminating null byte. Thus, a return value of 'sizeof(scopebuf)' means that the last character was dropped. - 'strcat' adds a terminating null byte to the string, thus if len == buflen, the null byte is written past the end of the buffer.

[ Upstream commit f376c43b ] bcm2835_register_gate is used as a callback for the clk_register member of bcm2835_clk_desc, which expects a struct clk_hw * return type but bcm2835_register_gate returns a struct clk *. This discrepancy is hidden by the fact that bcm2835_register_gate is cast to the typedef bcm2835_clk_register by the _REGISTER macro. This turns out to be a control flow integrity violation, which is how this was noticed. Change the return type of bcm2835_register_gate to be struct clk_hw * and use clk_hw_register_gate to do so. This should be a non-functional change as clk_register_gate calls clk_hw_register_gate anyways but this is needed to avoid issues with further changes.

It added a pr_debug() message which is issued when deadline timer validation succeeds. Well, issued only when CONFIG_DYNAMIC_DEBUG is enabled - otherwise pr_debug() calls get optimized away if DEBUG is not defined in the compilation unit.

[ Upstream commit 5d363120 ] This patch adds new config_ep_by_speed_and_alt function which extends the config_ep_by_speed about alt parameter. This additional parameter allows to find proper usb_ss_ep_comp_descriptor. Problem has appeared during testing f_tcm (BOT/UAS) driver function. f_tcm function for SS use array of headers for both BOT/UAS alternate setting: static struct usb_descriptor_header *uasp_ss_function_desc[] = { (struct usb_descriptor_header *) &bot_intf_desc, (struct usb_descriptor_header *) &uasp_ss_bi_desc, (struct usb_descriptor_header *) &bot_bi_ep_comp_desc, (struct usb_descriptor_header *) &uasp_ss_bo_desc, (struct usb_descriptor_header *) &bot_bo_ep_comp_desc, (struct usb_descriptor_header *) &uasp_intf_desc, (struct usb_descriptor_header *) &uasp_ss_bi_desc, (struct usb_descriptor_header *) &uasp_bi_ep_comp_desc, (struct usb_descriptor_header *) &uasp_bi_pipe_desc, (struct usb_descriptor_header *) &uasp_ss_bo_desc, (struct usb_descriptor_header *) &uasp_bo_ep_comp_desc, (struct usb_descriptor_header *) &uasp_bo_pipe_desc, (struct usb_descriptor_header *) &uasp_ss_status_desc, (struct usb_descriptor_header *) &uasp_status_in_ep_comp_desc, (struct usb_descriptor_header *) &uasp_status_pipe_desc, (struct usb_descriptor_header *) &uasp_ss_cmd_desc, (struct usb_descriptor_header *) &uasp_cmd_comp_desc, (struct usb_descriptor_header *) &uasp_cmd_pipe_desc, NULL, }; The first 5 descriptors are associated with BOT alternate setting, and others are associated with UAS. During handling UAS alternate setting f_tcm driver invokes config_ep_by_speed and this function sets incorrect companion endpoint descriptor in usb_ep object. Instead setting ep->comp_desc to uasp_bi_ep_comp_desc function in this case set ep->comp_desc to uasp_ss_bi_desc. This is due to the fact that it searches endpoint based on endpoint address: for_each_ep_desc(speed_desc, d_spd) { chosen_desc = (struct usb_endpoint_descriptor *)*d_spd; if (chosen_desc->bEndpoitAddress == _ep->address) goto ep_found; } And in result it uses the descriptor from BOT alternate setting instead UAS. Finally, it causes that controller driver during enabling endpoints detect that just enabled endpoint for bot. Signed-off-by:

It is not wrong, queue is not a pointer so if ep is not NULL, the address of queue cannot be NULL.

[ Upstream commit a0948ddb ] There is actually no need to ping the watchdog before disabling it during timeout change. Disabling the watchdog already takes care of resetting the counter. This fixes an issue during boot when the userspace watchdog handler takes over and the watchdog is already running. Opening the watchdog in this case leads to the first ping and directly after that without the required heartbeat delay a second ping issued by the set_timeout call. Due to the missing delay this resulted in a reset. Signed-off-by:

This is due to the fact that the DWC MSI code tries to register two IRQ domains for the same firmware node, without telling the low level code how to distinguish them (by setting a bus token). This further confuses debugfs which tries to create corresponding files for each domain. Fix it by tagging the inner domain as DOMAIN_BUS_NEXUS, which is the closest thing we have as to "generic MSI". Link: https://lore.kernel.org/r/20200501113921.366597-1-maz@kernel.orgSigned-off-by:

[ Upstream commit 7b38fd97 ] Except for Endpoints, we enable PTM at enumeration-time. Previously we did not account for the fact that Switch Downstream Ports are not permitted to have a PTM capability; their PTM behavior is controlled by the Upstream Port (PCIe r5.0, sec 7.9.16). Since Downstream Ports don't have a PTM capability, we did not mark them as "ptm_enabled", which meant that pci_enable_ptm() on an Endpoint failed because there was no PTM path to it. Mark Downstream Ports as "ptm_enabled" if their Upstream Port has PTM enabled. Fixes: eec097d4 ("PCI: Add pci_enable_ptm() for drivers to enable PTM on endpoints") Reported-by:

[ Upstream commit bba25915 ] The 'phy-mode' property is currently defined as 'rgmii' for Jetson Xavier. This indicates that the RGMII RX and TX delays are set by the MAC and the internal delays set by the PHY are not used. If the Marvell PHY driver is enabled, such that it is used and not the generic PHY, ethernet failures are seen (DHCP is failing to obtain an IP address) and this is caused because the Marvell PHY driver is disabling the internal RX and TX delays. For Jetson Xavier the internal PHY RX and TX delay should be used and so fix this by setting the 'phy-mode' to 'rgmii-id' and not 'rgmii'.

[ Upstream commit 61fb2482 ] When tcmu queues a new command - no matter whether in command ring or in qfull_queue - a cmd_id from IDR udev->commands is assigned to the command. If userspace sends a wrong command completion containing the cmd_id of a command on the qfull_queue, tcmu_handle_completions() finds the command in the IDR and calls tcmu_handle_completion() for it. This might do some nasty things because commands in qfull_queue do not have a valid dbi list. To fix this bug, we no longer add queued commands to the idr. Instead the cmd_id is assign when a command is written to the command ring. Due to this change I had to adapt the source code at several places where up to now an idr_for_each had been done.

[ Upstream commit bc138db1 ] The PCI Code and ID Assignment Specification changed capability ID 0 from reserved to a NULL capability in the v1.1 revision. The NULL capability is defined to include only the 16-bit capability header, ie. only the ID and next pointer. Unfortunately vfio-pci creates a map of config space, where ID 0 is used to reserve the standard type 0 header. Finding an actual capability with this ID therefore results in a bogus range marked in that map and conflicts with subsequent capabilities. As this seems to be a dummy capability anyway and we already support dropping capabilities, let's hide this one rather than delving into the potentially subtle dependencies within our map. Seen on an NVIDIA Tesla T4. Reviewed-by:

[ Upstream commit 12655446 ] The ps3_mm_region_destroy() and ps3_mm_vas_destroy() routines are called very late in the shutdown via kexec's mmu_cleanup_all routine. By the time mmu_cleanup_all runs it is too late to use udbg_printf, and calling it will cause PS3 systems to hang. Remove all debugging statements from ps3_mm_region_destroy() and ps3_mm_vas_destroy() and replace any error reporting with calls to lv1_panic. With this change builds with 'DEBUG' defined will not cause kexec reboots to hang, and builds with 'DEBUG' defined or not will end in lv1_panic if an error is encountered. Signed-off-by:
