tty: actually undefine superseded ASYNC flags

2021-05-22T08:57:29Z

[ Upstream commit d09845e98a05850a8094ea8fd6dd09a8e6824fff ] Some kernel-internal ASYNC flags have been superseded by tty-port flags and should no longer be used by kernel drivers. Fix the misspelled "__KERNEL__" compile guards which failed their sole purpose to break out-of-tree drivers that have not yet been updated.

net/ncsi: Add generic netlink family

2021-04-16T09:57:51Z

commit 955dc68cb9b23b42999cafe6df3684309bc686c6 upstream. Add a generic netlink family for NCSI. This supports three commands; NCSI_CMD_PKG_INFO which returns information on packages and their associated channels, NCSI_CMD_SET_INTERFACE which allows a specific package or package/channel combination to be set as the preferred choice, and NCSI_CMD_CLEAR_INTERFACE which clears any preferred setting.

crypto: af_alg - avoid undefined behavior accessing salg_name

2020-12-29T12:46:50Z

commit 92eb6c3060ebe3adf381fd9899451c5b047bb14d upstream. Commit 3f69cc60768b ("crypto: af_alg - Allow arbitrarily long algorithm names") made the kernel start accepting arbitrarily long algorithm names in sockaddr_alg. However, the actual length of the salg_name field stayed at the original 64 bytes. This is broken because the kernel can access indices >= 64 in salg_name, which is undefined behavior -- even though the memory that is accessed is still located within the sockaddr structure. It would only be defined behavior if the array were properly marked as arbitrary-length (either by making it a flexible array, which is the recommended way these days, or by making it an array of length 0 or 1). We can't simply change salg_name into a flexible array, since that would break source compatibility with userspace programs that embed sockaddr_alg into another struct, or (more commonly) declare a sockaddr_alg like 'struct sockaddr_alg sa = { .salg_name = "foo" };'. One solution would be to change salg_name into a flexible array only when '#ifdef __KERNEL__'. However, that would keep userspace without an easy way to actually use the longer algorithm names. Instead, add a new structure 'sockaddr_alg_new' that has the flexible array field, and expose it to both userspace and the kernel. Make the kernel use it correctly in alg_bind(). This addresses the syzbot report "UBSAN: array-index-out-of-bounds in alg_bind" (https://syzkaller.appspot.com/bug?extid=92ead4eb8e26a26d465e).

wireless: Use linux/stddef.h instead of stddef.h

2020-12-02T07:34:39Z

commit 1b9ae0c92925ac40489be526d67d0010d0724ce0 upstream. When compiling inside the kernel include linux/stddef.h instead of stddef.h. When I compile this header file in backports for power PC I run into a conflict with ptrdiff_t. I was unable to reproduce this in mainline kernel. I still would like to fix this problem in the kernel. Fixes: 6989310f5d43 ("wireless: Use offsetof instead of custom macro.")

media: videodev2.h: RGB BT2020 and HSV are always full range

2020-11-05T10:06:54Z

[ Upstream commit b305dfe2e93434b12d438434461b709641f62af4 ] The default RGB quantization range for BT.2020 is full range (just as for all the other RGB pixel encodings), not limited range. Update the V4L2_MAP_QUANTIZATION_DEFAULT macro and documentation accordingly. Also mention that HSV is always full range and cannot be limited range. When RGB BT2020 was introduced in V4L2 it was not clear whether it should be limited or full range, but full range is the right (and consistent) choice.

perf: correct SNOOPX field offset

2020-10-29T08:07:14Z

[ Upstream commit f3d301c1f2f5676465cdf3259737ea19cc82731f ] perf_event.h has macros that define the field offsets in the data_src bitmask in perf records. The SNOOPX and REMOTE offsets were both 37. These are distinct fields, and the bitfield layout in perf_mem_data_src confirms that SNOOPX should be at offset 38.
