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.

commit fd49e032 upstream. When building a kernel with CONFIG_PSTORE=y and CONFIG_CRYPTO not set, a build error happens: ld: fs/pstore/platform.o: in function `pstore_dump': platform.c:(.text+0x3f9): undefined reference to `crypto_comp_compress' ld: fs/pstore/platform.o: in function `pstore_get_backend_records': platform.c:(.text+0x784): undefined reference to `crypto_comp_decompress' This because some pstore code uses crypto_comp_(de)compress regardless of the CONFIG_CRYPTO status.

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.

commit 386a6539 upstream. After installing the Ubuntu Linux, the micmute led status is not correct. Users expect that the led is on if the capture is disabled, but with the current kernel, the led is off with the capture disabled. We tried the old linux kernel like linux-4.15, there is no this issue. It looks like we introduced this issue when switching to the led_cdev. Cc: <stable@vger.kernel.org> Signed-off-by:

[ Upstream commit d76f3351 ] In the case of TPROXY, bind_conflict optimizations for SO_REUSEADDR or SO_REUSEPORT are broken, possibly resulting in O(n) instead of O(1) bind behaviour or in the incorrect reuse of a bind. the kernel keeps track for each bind_bucket if all sockets in the bind_bucket support SO_REUSEADDR or SO_REUSEPORT in two fastreuse flags. These flags allow skipping the costly bind_conflict check when possible (meaning when all sockets have the proper SO_REUSE option). For every socket added to a bind_bucket, these flags need to be updated. As soon as a socket that does not support reuse is added, the flag is set to false and will never go back to true, unless the bind_bucket is deleted. Note that there is no mechanism to re-evaluate these flags when a socket is removed (this might make sense when removing a socket that would not allow reuse; this leaves room for a future patch). For this optimization to work, it is mandatory that these flags are properly initialized and updated. When a child socket is created from a listen socket in __inet_inherit_port, the TPROXY case could create a new bind bucket without properly initializing these flags, thus preventing the optimization to work. Alternatively, a socket not allowing reuse could be added to an existing bind bucket without updating the flags, causing bind_conflict to never be called as it should. Call inet_csk_update_fastreuse when __inet_inherit_port decides to create a new bind_bucket or use a different bind_bucket than the one of the listen socket.

[ 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. This change fixes kernel panic when this driver is used with AF_PACKET SOCK_RAW sockets.

[ Upstream commit 88fd1cb8 ] After @blk_fill_in_prog_lock is acquired there is an early out vnet situation that can occur. In that case, the rwlock needs to be released. Also, since @blk_fill_in_prog_lock is only acquired when @tp_version is exactly TPACKET_V3, only release it on that exact condition as well. And finally, add sparse annotation so that it is clearer that prb_fill_curr_block() and prb_clear_blk_fill_status() are acquiring and releasing @blk_fill_in_prog_lock, respectively. sparse is still unable to understand the balance, but the warnings are now on a higher level that make more sense.

[ 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.

[ Upstream commit a278f3d8 ] The '&&' command seems to have a bad effect when $(cmd_$(1)) exits with non-zero effect: the command failure is masked (despite `set -e`) and all but the first command of $(dep-cmd) is executed (successfully, as they are mostly printfs), thus overall returning 0 in the end. This means in practice that despite compilation errors, tools's build Makefile will return success. We see this very reliably with libbpf's Makefile, which doesn't get compilation error propagated properly. This in turns causes issues with selftests build, as well as bpftool and other projects that rely on building libbpf. The fix is simple: don't use &&. Given `set -e`, we don't need to chain commands with &&. The shell will exit on first failure, giving desired behavior and propagating error properly.

[ Upstream commit dfa03fff ] The size of the CPU affinity mask must be large enough for systems with a very large number of CPUs. Otherwise, tests which try to determine the first online CPU by calling sched_getaffinity() will fail. This makes sure that the size of the allocated affinity mask is dependent on the number of CPUs as reported by get_nprocs_conf().

[ Upstream commit 788abc6d ] Alter the rtl8366_vlan_add() to call rtl8366_set_vlan() inside the loop that goes over all VIDs since we now properly support calling that function more than once. Augment the loop to postincrement as this is more intuitive. The loop moved past the last VID but called rtl8366_set_vlan() with the port number instead of the VID, assuming a 1-to-1 correspondence between ports and VIDs. This was also a bug.

[ Upstream commit 15ab7906 ] The RTL8366 would not handle adding new members (ports) to a VLAN: the code assumed that ->port_vlan_add() was only called once for a single port. When intializing the switch with .configure_vlan_while_not_filtering set to true, the function is called numerous times for adding all ports to VLAN1, which was something the code could not handle. Alter rtl8366_set_vlan() to just |= new members and untagged flags to 4k and MC VLAN table entries alike. This makes it possible to just add new ports to a VLAN. Put in some helpful debug code that can be used to find any further bugs here. Cc: DENG Qingfang <dqfext@gmail.com> Cc: Mauri Sandberg <sandberg@mailfence.com> Reviewed-by:
