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.

The SafeSetID LSM uses the security_task_fix_setuid hook to filter set*uid() syscalls according to its configured security policy. In preparation for adding analagous support in the LSM for set*gid() syscalls, we add the requisite hook here. Tested by putting print statements in the security_task_fix_setgid hook and seeing them get hit during kernel boot. Signed-off-by:

This reverts commit a43a67a2. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option. Link: https://lore.kernel.org/linux-btrfs/20200528192103.xm45qoxqmkw7i5yl@fiona/Signed-off-by:

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. This path was missed by commit 9d1f6447 ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled"). Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti(). Fixes: 9d1f6447 ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled") Signed-off-by:
