[ Upstream commit 605b3bec ] spidev will make a big fuss if a device tree node binds a device by using "spidev" as the node's compatible property. However, the logic for this isn't looking for "spidev" in the compatible, but rather checking that the device is NOT compatible with spidev's list of devices. This causes a false positive if a device not named "rohm,dh2228fv", etc. binds to spidev, even if a means other than putting "spidev" in the device tree was used. E.g., the sysfs driver_override attribute. Signed-off-by:

[ Upstream commit d17f477c ] The code was written under the assumption that the regmap_update_bits() would mask the bits in the mask and set the bits in the value. It missed the points that it will not set bits in the value unless these are also masked in the mask. Set value bits that are not in the mask will simply be ignored.

[ Upstream commit de8978c3 ] Certain devices don't work well when a transmit FIFO underrun or receive FIFO overrun occurs. Example is the SAF400x radio chip when running at high speed which leads to garbage being sent to/received from the chip. In which case, it should stall waiting for further data to be available before proceeding. This patch unset the NOSTALL bit in CFGR1 by default to prevent this issue. Signed-off-by:

[ Upstream commit 29724956 ] XDP can modify (and resize) the Ethernet header in the packet. There is a bug in generic-XDP, because skb->protocol and skb->pkt_type are setup before reaching (netif_receive_)generic_xdp. This bug was hit when XDP were popping VLAN headers (changing eth->h_proto), as skb->protocol still contains VLAN-indication (ETH_P_8021Q) causing invocation of skb_vlan_untag(skb), which corrupt the packet (basically popping the VLAN again). This patch catch if XDP changed eth header in such a way, that SKB fields needs to be updated. V2: on request from Song Liu, use ETH_HLEN instead of mac_len, in __skb_push() as eth_type_trans() use ETH_HLEN in paired skb_pull_inline().

[ Upstream commit 8af03d1a ] In btf_parse_hdr(), the length of the btf data header is firstly copied from the user space to 'hdr_len' and checked to see whether it is larger than 'btf_data_size'. If yes, an error code EINVAL is returned. Otherwise, the whole header is copied again from the user space to 'btf->hdr'. However, after the second copy, there is no check between 'btf->hdr->hdr_len' and 'hdr_len' to confirm that the two copies get the same value. Given that the btf data is in the user space, a malicious user can race to change the data between the two copies. By doing so, the user can provide malicious data to the kernel and cause undefined behavior. This patch adds a necessary check after the second copy, to make sure 'btf->hdr->hdr_len' has the same value as 'hdr_len'. Otherwise, an error code EINVAL will be returned. Signed-off-by:

[ Upstream commit 51fbf14f ] The only use of KEXEC_BACKUP_SRC_END is as an argument to walk_system_ram_res(): int crash_load_segments(struct kimage *image) { ... walk_system_ram_res(KEXEC_BACKUP_SRC_START, KEXEC_BACKUP_SRC_END, image, determine_backup_region); walk_system_ram_res() expects "start, end" arguments that are inclusive, i.e., the range to be walked includes both the start and end addresses. KEXEC_BACKUP_SRC_END was previously defined as (640 * 1024UL), which is the first address *past* the desired 0-640KB range. Define KEXEC_BACKUP_SRC_END as (640 * 1024UL - 1) so the KEXEC_BACKUP_SRC region is [0-0x9ffff], not [0-0xa0000].

Javier González authored
[ Upstream commit d672d92d ] OCSSD 2.0 defines the amount of data that the host must buffer per chunk to guarantee reads through the geometry field mw_cunits. This value is the base that pblk uses to determine the size of its read buffer. Currently, this size is set to be the closes power-of-2 to mw_cunits times the number of parallel units available to the pblk instance for each open line (currently one). When an entry (4KB) is put in the buffer, the L2P table points to it. As the buffer wraps up, the L2P is updated to point to addresses on the device, thus guaranteeing mw_cunits at a chunk level. However, given that pblk cannot write to the device under ws_min (normally ws_opt), there might be a window in which the buffer starts wrapping up and updating L2P entries before the mw_cunits value in a chunk has been surpassed. In order not to violate the mw_cunits constrain in this case, account for ws_opt on the read buffer creation. Signed-off-by:

[ Upstream commit 4b5d56ed ] rqd.error is masked by the return value of pblk_submit_io_sync. The rqd structure is then passed on to the end_io function, which assumes that any error should lead to a chunk being marked offline/bad. Since the pblk_submit_io_sync can fail before the command is issued to the device, the error value maybe not correspond to a media failure, leading to chunks being immaturely retired. Also, the pblk_blk_erase_sync function prints an error message in case the erase fails. Since the caller prints an error message by itself, remove the error message in this function. Signed-off-by:

[ Upstream commit 1eb8d738 ] Flushing the workqueue can cause operations to happen which might call gfs2_log_reserve(), or get stuck waiting for locks taken by such operations. gfs2_log_reserve() can io_schedule().

[ Upstream commit a26ac6c1 ] In isif_probe(), there is a while loop to get the ISIF base address and linearization table0 and table1 address. In the loop body, the function platform_get_resource() is called to get the resource. If platform_get_resource() returns NULL, the loop is terminated and the execution goes to 'fail_nobase_res'. Suppose the loop is terminated at the first iteration because platform_get_resource() returns NULL and the execution goes to 'fail_nobase_res'. Given that there is another while loop at 'fail_nobase_res' and i equals to 0, one iteration of the second while loop will be executed. However, the second while loop does not check the return value of platform_get_resource(). This can cause a NULL pointer dereference bug if the return value is a NULL pointer. This patch avoids the above issue by adding a check in the second while loop after the call to platform_get_resource(). Signed-off-by:

[ Upstream commit e5f3530c ] The CBM overlap test is used to manage the allocations of RDT resources where overlap is possible between resource groups. When a resource group is in exclusive mode then there should be no overlap between resource groups. The current overlap test only considers overlap between the same resources, for example, that usage of a RDT_RESOURCE_L2DATA resource in one resource group does not overlap with usage of a RDT_RESOURCE_L2DATA resource in another resource group. The problem with this is that it allows overlap between a RDT_RESOURCE_L2DATA resource in one resource group with a RDT_RESOURCE_L2CODE resource in another resource group - even if both resource groups are in exclusive mode. This is a problem because even though these appear to be different resources they end up sharing the same underlying hardware and thus does not fulfill the user's request for exclusive use of hardware resources. Fix this by including the CDP peer (if there is one) in every CBM overlap test. This does not impact the overlap between resources within the same exclusive resource group that is allowed.

[ Upstream commit 521348b0 ] Introduce a utility that, when provided with a RDT resource and an instance of this RDT resource (a RDT domain), would return pointers to the RDT resource and RDT domain that share the same hardware. This is specific to the CDP resources that share the same hardware. For example, if a pointer to the RDT_RESOURCE_L2DATA resource (struct rdt_resource) and a pointer to an instance of this resource (struct rdt_domain) is provided, then it will return a pointer to the RDT_RESOURCE_L2CODE resource as well as the specific instance that shares the same hardware as the provided rdt_domain. This utility is created in support of the "exclusive" resource group mode where overlap of resource allocation between resource groups need to be avoided. The overlap test need to consider not just the matching resources, but also the resources that share the same hardware. Temporarily mark it as unused in support of patch testing to avoid compile warnings until it is used. Fixes: 49f7b4ef ("x86/intel_rdt: Enable setting of exclusive mode") Signed-off-by:

[ Upstream commit aae3394e ] The framebuffer options and devices menu is unintentionally split or broken because some items in it do not depend on FB (including several under omap and mmp). Fix this by moving FB_CMDLINE, FB_NOTIFY, and FB_CLPS711X_OLD to just before the FB Kconfig symbol definition and by moving the omap, omap2, and mmp menus to last, following FB_SM712. Also, the FB_VIA dependencies are duplicated by both being inside an "if FB_VIA/endif" block and "depends on FB_VIA", so drop the "depends on FB_VIA" lines since they are redundant.
