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

2024-11-08T15:19:15Z

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.

m68k: amiga: Turn off Warp1260 interrupts during boot

2024-08-19T03:32:03Z

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.

hugetlb_encode.h: fix undefined behaviour (34 << 26)

2024-07-05T07:00:26Z

commit 710bb68c2e3a24512e2d2bae470960d7488e97b1 upstream. Left-shifting past the size of your datatype is undefined behaviour in C. The literal 34 gets the type `int`, and that one is not big enough to be left shifted by 26 bits. An `unsigned` is long enough (on any machine that has at least 32 bits for their ints.) For uniformity, we mark all the literals as unsigned. But it's only really needed for HUGETLB_FLAG_ENCODE_16GB. Thanks to Randy Dunlap for an initial review and suggestion.

netfilter: nf_tables: fix table flag updates

2024-06-16T11:23:42Z

commit 179d9ba5559a756f4322583388b3213fe4e391b0 upstream. The dormant flag need to be updated from the preparation phase, otherwise, two consecutive requests to dorm a table in the same batch might try to remove the same hooks twice, resulting in the following warning: hook not found, pf 3 num 0 WARNING: CPU: 0 PID: 334 at net/netfilter/core.c:480 __nf_unregister_net_hook+0x1eb/0x610 net/netfilter/core.c:480 Modules linked in: CPU: 0 PID: 334 Comm: kworker/u4:5 Not tainted 5.12.0-syzkaller #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 Workqueue: netns cleanup_net RIP: 0010:__nf_unregister_net_hook+0x1eb/0x610 net/netfilter/core.c:480 This patch is a partial revert of 0ce7cf4127f1 ("netfilter: nftables: update table flags from the commit phase") to restore the previous behaviour. However, there is still another problem: A batch containing a series of dorm-wakeup-dorm table and vice-versa also trigger the warning above since hook unregistration happens from the preparation phase, while hook registration occurs from the commit phase. To fix this problem, this patch adds two internal flags to annotate the original dormant flag status which are __NFT_TABLE_F_WAS_DORMANT and __NFT_TABLE_F_WAS_AWAKEN, to restore it from the abort path. The __NFT_TABLE_F_UPDATE bitmask allows to handle the dormant flag update with one single transaction.

Revert "y2038: rusage: use __kernel_old_timeval"

2024-05-02T14:17:14Z

This reverts commit d5e38d6b84d6d21a4f8a4f555a0908b6d9ffe224, which was commit bdd565f817a74b9e30edec108f7cb1dbc762b8a6 upstream. It broke the build for alpha and that can't be fixed without backporting other more intrusive y2038 changes. This was not a completely clean revert as the affected code in getrusage() was moved by subsequent changes. Signed-off-by: Ben Hutchings Signed-off-by: Greg Kroah-Hartman

y2038: rusage: use __kernel_old_timeval

2024-03-15T14:48:17Z

[ Upstream commit bdd565f817a74b9e30edec108f7cb1dbc762b8a6 ] There are two 'struct timeval' fields in 'struct rusage'. Unfortunately the definition of timeval is now ambiguous when used in user space with a libc that has a 64-bit time_t, and this also changes the 'rusage' definition in user space in a way that is incompatible with the system call interface. While there is no good solution to avoid all ambiguity here, change the definition in the kernel headers to be compatible with the kernel ABI, using __kernel_old_timeval as an unambiguous base type. In previous discussions, there was also a plan to add a replacement for rusage based on 64-bit timestamps and nanosecond resolution, i.e. 'struct __kernel_timespec'. I have patches for that as well, if anyone thinks we should do that.
