net: qrtr: correct types of trace event parameters

2023-05-17T09:47:50+00:00

[ Upstream commit 054fbf7ff8143d35ca7d3bb5414bb44ee1574194 ] The arguments passed to the trace events are of type unsigned int, however the signature of the events used __le32 parameters. I may be missing the point here, but sparse flagged this and it does seem incorrect to me. net/qrtr/ns.c: note: in included file (through include/trace/trace_events.h, include/trace/define_trace.h, include/trace/events/qrtr.h): ./include/trace/events/qrtr.h:11:1: warning: cast to restricted __le32 ./include/trace/events/qrtr.h:11:1: warning: restricted __le32 degrades to integer ./include/trace/events/qrtr.h:11:1: warning: restricted __le32 degrades to integer ...

f2fs: Fix f2fs_truncate_partial_nodes ftrace event

[ Upstream commit 0b04d4c0542e8573a837b1d81b94209e48723b25 ] Fix the nid_t field so that its size is correctly reported in the text format embedded in trace.dat files. As it stands, it is reported as being of size 4: field:nid_t nid[3]; offset:24; size:4; signed:0; Instead of 12: field:nid_t nid[3]; offset:24; size:12; signed:0; This also fixes the reported offset of subsequent fields so that they match with the actual struct layout.

ext4: disable fast-commit of encrypted dir operations

2023-01-14T09:16:51+00:00

commit 0fbcb5251fc81b58969b272c4fb7374a7b922e3e upstream. fast-commit of create, link, and unlink operations in encrypted directories is completely broken because the unencrypted filenames are being written to the fast-commit journal instead of the encrypted filenames. These operations can't be replayed, as encryption keys aren't present at journal replay time. It is also an information leak. Until if/when we can get this working properly, make encrypted directory operations ineligible for fast-commit. Note that fast-commit operations on encrypted regular files continue to be allowed, as they seem to work.

No upstream commit exists. This imports the io_uring codebase from 5.15.85, wholesale. Changes from that code base: - Drop IOCB_ALLOC_CACHE, we don't have that in 5.10. - Drop MKDIRAT/SYMLINKAT/LINKAT. Would require further VFS backports, and we don't support these in 5.10 to begin with. - sock_from_file() old style calling convention. - Use compat_get_bitmap() only for CONFIG_COMPAT=y Signed-off-by: Jens Axboe Signed-off-by: Greg Kroah-Hartman

spmi: trace: fix stack-out-of-bound access in SPMI tracing functions

2022-08-21T13:16:15+00:00

commit 2af28b241eea816e6f7668d1954f15894b45d7e3 upstream. trace_spmi_write_begin() and trace_spmi_read_end() both call memcpy() with a length of "len + 1". This leads to one extra byte being read beyond the end of the specified buffer. Fix this out-of-bound memory access by using a length of "len" instead. Here is a KASAN log showing the issue: BUG: KASAN: stack-out-of-bounds in trace_event_raw_event_spmi_read_end+0x1d0/0x234 Read of size 2 at addr ffffffc0265b7540 by task thermal@2.0-ser/1314 ...
