BugLink: https://bugs.launchpad.net/bugs/1892822 commit df43dd52 upstream. The IPQ806x does not appear to have a functional multicast ethernet address filter. This was observed as a failure to correctly receive IPv6 packets on a LAN to the all stations address. Checking the vendor driver shows that it does not attempt to enable the multicast filter and instead falls back to receiving all multicast packets, internally setting ALLMULTI. Use the new fallback support in the dwmac1000 driver to correctly achieve the same with the mainline IPQ806x driver. Confirmed to fix IPv6 functionality on an RB3011 router.

BugLink: https://bugs.launchpad.net/bugs/1892822 commit 0c83b277 upstream. Recently random.h started including percpu.h (see commit f227e3ec ("random32: update the net random state on interrupt and activity")), which broke corenet64_smp_defconfig: In file included from /linux/arch/powerpc/include/asm/paca.h:18, from /linux/arch/powerpc/include/asm/percpu.h:13, from /linux/include/linux/random.h:14, from /linux/lib/uuid.c:14: /linux/arch/powerpc/include/asm/mmu.h:139:22: error: unknown type name 'next_tlbcam_idx' 139 | DECLARE_PER_CPU(int, next_tlbcam_idx); This is due to a circular header dependency: asm/mmu.h includes asm/percpu.h, which includes asm/paca.h, which includes asm/mmu.h Which means DECLARE_PER_CPU() isn't defined when mmu.h needs it. We can fix it by moving the include of paca.h below the include of asm-generic/percpu.h. This moves the include of paca.h out of the #ifdef __powerpc64__, but that is OK because paca.h is almost entirely inside #ifdef CONFIG_PPC64 anyway. It also moves the include of paca.h out of the #ifdef CONFIG_SMP, which could possibly break something, but seems to have no ill effects.

BugLink: https://bugs.launchpad.net/bugs/1892822 commit 4f26433e upstream. While logging an inode, at copy_items(), if we fail to lookup the checksums for an extent we release the destination path, free the ins_data array and then return immediately. However a previous iteration of the for loop may have added checksums to the ordered_sums list, in which case we leak the memory used by them. So fix this by making sure we iterate the ordered_sums list and free all its checksums before returning.

BugLink: https://bugs.launchpad.net/bugs/1892822 commit bf53d468 upstream. In try_to_merge_free_space we attempt to find entries to the left and right of the entry we are adding to see if they can be merged. We search for an entry past our current info (saved into right_info), and then if right_info exists and it has a rb_prev() we save the rb_prev() into left_info. However there's a slight problem in the case that we have a right_info, but no entry previous to that entry. At that point we will search for an entry just before the info we're attempting to insert. This will simply find right_info again, and assign it to left_info, making them both the same pointer. Now if right_info _can_ be merged with the range we're inserting, we'll add it to the info and free right_info. However further down we'll access left_info, which was right_info, and thus get a use-after-free. Fix this by only searching for the left entry if we don't find a right entry at all. The CVE referenced had a specially crafted file system that could trigger this use-after-free. However with the tree checker improvements we no longer trigger the conditions for the UAF. But the original conditions still apply, hence this fix.

BugLink: https://bugs.launchpad.net/bugs/1892822 commit 1b7ecc24 upstream. Further investigation of the L-R swap problem on the MS2109 reveals that the problem isn't that the channels are swapped, but rather that they are swapped and also out of phase by one sample. In other words, the issue is actually that the very first frame that comes from the hardware is a half-frame containing only the right channel, and after that everything becomes offset. So introduce a new quirk field to drop the very first 2 bytes that come in after the format is configured and a capture stream starts. This puts the channels in phase and in the correct order.

BugLink: https://bugs.launchpad.net/bugs/1892822 commit 270ef410 upstream. If the minix filesystem tries to map a very large logical block number to its on-disk location, block_to_path() can return offsets that are too large, causing out-of-bounds memory accesses when accessing indirect index blocks. This should be prevented by the check against the maximum file size, but this doesn't work because the maximum file size is read directly from the on-disk superblock and isn't validated itself. Fix this by validating the maximum file size at mount time.

BugLink: https://bugs.launchpad.net/bugs/1892822 commit c06c7660 upstream. clang static analysis flags this error qat_uclo.c:297:3: warning: Attempt to free released memory [unix.Malloc] kfree(*init_tab_base); ^~~~~~~~~~~~~~~~~~~~~ When input *init_tab_base is null, the function allocates memory for the head of the list. When there is problem allocating other list elements the list is unwound and freed. Then a check is made if the list head was allocated and is also freed. Keeping track of the what may need to be freed is the variable 'tail_old'. The unwinding/freeing block is while (tail_old) { mem_init = tail_old->next; kfree(tail_old); tail_old = mem_init; } The problem is that the first element of tail_old is also what was allocated for the list head init_header = kzalloc(sizeof(*init_header), GFP_KERNEL); ... *init_tab_base = init_header; flag = 1; } tail_old = init_header; So *init_tab_base/init_header are freed twice. There is another problem. When the input *init_tab_base is non null the tail_old is calculated by traveling down the list to first non null entry. tail_old = init_header; while (tail_old->next) tail_old = tail_old->next; When the unwinding free happens, the last entry of the input list will be freed. So the freeing needs a general changed. If locally allocated the first element of tail_old is freed, else it is skipped. As a bit of cleanup, reset *init_tab_base if it came in as null.

BugLink: https://bugs.launchpad.net/bugs/1892822 [ Upstream commit c7ca03c2 ] 1. Added a skb->len check This driver expects upper layers to include a pseudo header of 1 byte when passing down a skb for transmission. This driver will read this 1-byte header. This patch added a skb->len check before reading the header to make sure the header exists. 2. Changed to use needed_headroom instead of hard_header_len to request necessary headroom to be allocated In net/packet/af_packet.c, the function packet_snd first reserves a headroom of length (dev->hard_header_len + dev->needed_headroom). Then if the socket is a SOCK_DGRAM socket, it calls dev_hard_header, which calls dev->header_ops->create, to create the link layer header. If the socket is a SOCK_RAW socket, it "un-reserves" a headroom of length (dev->hard_header_len), and assumes the user to provide the appropriate link layer header. So according to the logic of af_packet.c, dev->hard_header_len should be the length of the header that would be created by dev->header_ops->create. However, this driver doesn't provide dev->header_ops, so logically dev->hard_header_len should be 0. So we should use dev->needed_headroom instead of dev->hard_header_len to request necessary headroom to be allocated.

BugLink: https://bugs.launchpad.net/bugs/1892822 [ Upstream commit f46fe79f ] This patch causes pcs_parse_pinconf() to return -ENOTSUPP when no pinctrl_map is added. The current behavior is to return 0 when !PCS_HAS_PINCONF or !nconfs. Thus pcs_parse_one_pinctrl_entry() incorrectly assumes that a map was added and sets num_maps = 2. Analysis: ========= The function pcs_parse_one_pinctrl_entry() calls pcs_parse_pinconf() if PCS_HAS_PINCONF is enabled. The function pcs_parse_pinconf() returns 0 to indicate there was no error and num_maps is then set to 2: 980 static int pcs_parse_one_pinctrl_entry(struct pcs_device *pcs, 981 struct device_node *np, 982 struct pinctrl_map **map, 983 unsigned *num_maps, 984 const char **pgnames) 985 { <snip> 1053 (*map)->type = PIN_MAP_TYPE_MUX_GROUP; 1054 (*map)->data.mux.group = np->name; 1055 (*map)->data.mux.function = np->name; 1056 1057 if (PCS_HAS_PINCONF && function) { 1058 res = pcs_parse_pinconf(pcs, np, function, map); 1059 if (res) 1060 goto free_pingroups; 1061 *num_maps = 2; 1062 } else { 1063 *num_maps = 1; 1064 } However, pcs_parse_pinconf() will also return 0 if !PCS_HAS_PINCONF or !nconfs. I believe these conditions should indicate that no map was added by returning -ENOTSUPP. Otherwise pcs_parse_one_pinctrl_entry() will set num_maps = 2 even though no maps were successfully added, as it does not reach "m++" on line 940: 895 static int pcs_parse_pinconf(struct pcs_device *pcs, struct device_node *np, 896 struct pcs_function *func, 897 struct pinctrl_map **map) 898 899 { 900 struct pinctrl_map *m = *map; <snip> 917 /* If pinconf isn't supported, don't parse properties in below. */ 918 if (!PCS_HAS_PINCONF) 919 return 0; 920 921 /* cacluate how much properties are supported in current node */ 922 for (i = 0; i < ARRAY_SIZE(prop2); i++) { 923 if (of_find_property(np, prop2[i].name, NULL)) 924 nconfs++; 925 } 926 for (i = 0; i < ARRAY_SIZE(prop4); i++) { 927 if (of_find_property(np, prop4[i].name, NULL)) 928 nconfs++; 929 } 930 if (!nconfs) 919 return 0; 932 933 func->conf = devm_kcalloc(pcs->dev, 934 nconfs, sizeof(struct pcs_conf_vals), 935 GFP_KERNEL); 936 if (!func->conf) 937 return -ENOMEM; 938 func->nconfs = nconfs; 939 conf = &(func->conf[0]); 940 m++; This situtation will cause a boot failure [0] on the BeagleBone Black (AM3358) when am33xx_pinmux node in arch/arm/boot/dts/am33xx-l4.dtsi has compatible = "pinconf-single" instead of "pinctrl-single". The patch fixes this issue by returning -ENOSUPP when !PCS_HAS_PINCONF or !nconfs, so that pcs_parse_one_pinctrl_entry() will know that no map was added. Logic is also added to pcs_parse_one_pinctrl_entry() to distinguish between -ENOSUPP and other errors. In the case of -ENOSUPP, num_maps is set to 1 as it is valid for pinconf to be enabled and a given pin group to not any pinconf properties.

BugLink: https://bugs.launchpad.net/bugs/1892822 [ Upstream commit 2505a210 ] If fw_csr_string() returns -ENOENT, then "name" is uninitialized. So then the "strlen(model_names[i]) <= name_len" is true because strlen() is unsigned and -ENOENT is type promoted to a very high positive value. Then the "strncmp(name, model_names[i], name_len)" uses uninitialized data because "name" is uninitialized. Fixes: 92374e88 ("[media] firedtv: drop obsolete backend abstraction") Signed-off-by:
