media: uapi/linux/cec.h: cec_msg_set_reply_to: zero flags

2024-10-17T13:08:23+00:00

commit 599f6899051cb70c4e0aa9fd591b9ee220cb6f14 upstream. The cec_msg_set_reply_to() helper function never zeroed the struct cec_msg flags field, this can cause unexpected behavior if flags was uninitialized to begin with.

net: geneve: support IPv4/IPv6 as inner protocol

2024-10-17T13:07:41+00:00

[ Upstream commit 435fe1c0c1f74b682dba85641406abf4337aade6 ] This patch adds support for encapsulating IPv4/IPv6 within GENEVE. In order to use this, a new IFLA_GENEVE_INNER_PROTO_INHERIT flag needs to be provided at device creation. This property cannot be changed for the time being. In case IP traffic is received on a non-tun device the drop count is increased.

binfmt_misc: pass binfmt_misc flags to the interpreter

2024-09-04T11:17:42+00:00

commit 2347961b11d4079deace3c81dceed460c08a8fc1 upstream. It can be useful to the interpreter to know which flags are in use. For instance, knowing if the preserve-argv[0] is in use would allow to skip the pathname argument. This patch uses an unused auxiliary vector, AT_FLAGS, to add a flag to inform interpreter if the preserve-argv[0] is enabled. Note by Helge Deller: The real-world user of this patch is qemu-user, which needs to know if it has to preserve the argv[0]. See Debian bug #970460.

m68k: amiga: Turn off Warp1260 interrupts during boot

2024-08-19T03:40:57+00:00

commit 1d8491d3e726984343dd8c3cdbe2f2b47cfdd928 upstream. On an Amiga 1200 equipped with a Warp1260 accelerator, an interrupt storm coming from the accelerator board causes the machine to crash in local_irq_enable() or auto_irq_enable(). Disabling interrupts for the Warp1260 in amiga_parse_bootinfo() fixes the problem.

fanotify: introduce FAN_MARK_IGNORE

2024-06-21T12:53:46+00:00

[ Upstream commit e252f2ed1c8c6c3884ab5dd34e003ed21f1fe6e0 ] This flag is a new way to configure ignore mask which allows adding and removing the event flags FAN_ONDIR and FAN_EVENT_ON_CHILD in ignore mask. The legacy FAN_MARK_IGNORED_MASK flag would always ignore events on directories and would ignore events on children depending on whether the FAN_EVENT_ON_CHILD flag was set in the (non ignored) mask. FAN_MARK_IGNORE can be used to ignore events on children without setting FAN_EVENT_ON_CHILD in the mark's mask and will not ignore events on directories unconditionally, only when FAN_ONDIR is set in ignore mask. The new behavior is non-downgradable. After calling fanotify_mark() with FAN_MARK_IGNORE once, calling fanotify_mark() with FAN_MARK_IGNORED_MASK on the same object will return EEXIST error. Setting the event flags with FAN_MARK_IGNORE on a non-dir inode mark has no meaning and will return ENOTDIR error. The meaning of FAN_MARK_IGNORED_SURV_MODIFY is preserved with the new FAN_MARK_IGNORE flag, but with a few semantic differences: 1. FAN_MARK_IGNORED_SURV_MODIFY is required for filesystem and mount marks and on an inode mark on a directory. Omitting this flag will return EINVAL or EISDIR error. 2. An ignore mask on a non-directory inode that survives modify could never be downgraded to an ignore mask that does not survive modify. With new FAN_MARK_IGNORE semantics we make that rule explicit - trying to update a surviving ignore mask without the flag FAN_MARK_IGNORED_SURV_MODIFY will return EEXIST error. The conveniene macro FAN_MARK_IGNORE_SURV is added for (FAN_MARK_IGNORE | FAN_MARK_IGNORED_SURV_MODIFY), because the common case should use short constant names.

fanotify: implement "evictable" inode marks

2024-06-21T12:53:40+00:00

[ Upstream commit 7d5e005d982527e4029b0139823d179986e34cdc ] When an inode mark is created with flag FAN_MARK_EVICTABLE, it will not pin the marked inode to inode cache, so when inode is evicted from cache due to memory pressure, the mark will be lost. When an inode mark with flag FAN_MARK_EVICATBLE is updated without using this flag, the marked inode is pinned to inode cache. When an inode mark is updated with flag FAN_MARK_EVICTABLE but an existing mark already has the inode pinned, the mark update fails with error EEXIST. Evictable inode marks can be used to setup inode marks with ignored mask to suppress events from uninteresting files or directories in a lazy manner, upon receiving the first event, without having to iterate all the uninteresting files or directories before hand. The evictbale inode mark feature allows performing this lazy marks setup without exhausting the system memory with pinned inodes. This change does not enable the feature yet.

fanotify: report old and/or new parent+name in FAN_RENAME event

2024-06-21T12:53:28+00:00

[ Upstream commit 7326e382c21e9c23c89c88369afdc90b82a14da8 ] In the special case of FAN_RENAME event, we report old or new or both old and new parent+name. A single info record will be reported if either the old or new dir is watched and two records will be reported if both old and new dir (or their filesystem) are watched. The old and new parent+name are reported using new info record types FAN_EVENT_INFO_TYPE_{OLD,NEW}_DFID_NAME, so if a single info record is reported, it is clear to the application, to which dir entry the fid+name info is referring to.
