This flaw is detected by smatch: drivers/net/wireless/realtek/rtw88/mac.c:748 __rtw_download_firmware() warn: missing unwind goto? Though most things of dlfw_fail have been done by download_firmware_end_flow() and wlan_cpu_enable(), an exception is that download_firmware_end_flow() clear BIT_MCUFWDL_EN bit conditionally. So, make this change to clear the bit. Reported-by:

Matthieu Baerts says: ==================== mptcp: unify PM interfaces These patches from Geliang better isolate the two MPTCP path-managers by avoiding calling userspace PM functions from the in-kernel PM. Instead, new functions declared in pm.c directly dispatch to the right PM. In addition to have a clearer code, this also avoids a bit of duplicated checks. This is a refactoring, there is no behaviour change intended here. ==================== Link: https://lore.kernel.org/r/20230608-upstream-net-next-20230608-mptcp-unify-pm-interfaces-v1-0-b301717c9ff5@tessares.netSigned-off-by:

Recent iOS releases support CDC NCM encapsulation on RX. This mode is the default on macOS and Windows. In this mode, an iOS device may include one or more Ethernet frames inside a single URB. Freshly booted iOS devices start in legacy mode, but are put into NCM mode by the official Apple driver. When reconnecting such a device from a macOS/Windows machine to a Linux host, the device stays in NCM mode, making it unusable with the legacy ipheth driver code. To correctly support such a device, the driver has to either support the NCM mode too, or put the device back into legacy mode. To match the behaviour of the macOS/Windows driver, and since there is no documented control command to revert to legacy mode, implement NCM support. The device is attempted to be put into NCM mode by default, and falls back to legacy mode if the attempt fails. Signed-off-by:

Merge branch 'splice-net-rewrite-splice-to-socket-fix-splice_f_more-and-handle-msg_splice_pages-in-af_tls' David Howells says: ==================== splice, net: Rewrite splice-to-socket, fix SPLICE_F_MORE and handle MSG_SPLICE_PAGES in AF_TLS Here are patches to do the following: (1) Block MSG_SENDPAGE_* flags from leaking into ->sendmsg() from userspace, whilst allowing splice_to_socket() to pass them in. (2) Allow MSG_SPLICE_PAGES to be passed into tls_*_sendmsg(). Until support is added, it will be ignored and a splice-driven sendmsg() will be treated like a normal sendmsg(). TCP, UDP, AF_UNIX and Chelsio-TLS already handle the flag in net-next. (3) Replace a chain of functions to splice-to-sendpage with a single function to splice via sendmsg() with MSG_SPLICE_PAGES. This allows a bunch of pages to be spliced from a pipe in a single call using a bio_vec[] and pushes the main processing loop down into the bowels of the protocol driver rather than repeatedly calling in with a page at a time. (4) Provide a ->splice_eof() op[2] that allows splice to signal to its output that the input observed a premature EOF and that the caller didn't flag SPLICE_F_MORE, thereby allowing a corked socket to be flushed. This attempts to maintain the current behaviour. It is also not called if we didn't manage to read any data and so didn't called the actor function. This needs routing though several layers to get it down to the network protocol. [!] Note that I chose not to pass in any flags - I'm not sure it's particularly useful to pass in the splice flags; I also elected not to return any error code - though we might actually want to do that. (5) Provide tls_{device,sw}_splice_eof() to flush a pending TLS record if there is one. (6) Provide splice_eof() for UDP, TCP, Chelsio-TLS and AF_KCM. AF_UNIX doesn't seem to pay attention to the MSG_MORE or MSG_SENDPAGE_NOTLAST flags. (7) Alter the behaviour of sendfile() and fix SPLICE_F_MORE/MSG_MORE signalling[1] such SPLICE_F_MORE is always signalled until we have read sufficient data to finish the request. If we get a zero-length before we've managed to splice sufficient data, we now leave the socket expecting more data and leave it to userspace to deal with it. (8) Make AF_TLS handle the MSG_SPLICE_PAGES internal sendmsg flag. MSG_SPLICE_PAGES is an internal hint that tells the protocol that it should splice the pages supplied if it can. Its sendpage implementations are then turned into wrappers around that.

Convert tls_device_sendpage() to use sendmsg() with MSG_SPLICE_PAGES rather than directly splicing in the pages itself. With that, the tls_iter_offset union is no longer necessary and can be replaced with an iov_iter pointer and the zc_page argument to tls_push_data() can also be removed. This allows ->sendpage() to be replaced by something that can handle multiple multipage folios in a single transaction. Signed-off-by:

splice_direct_to_actor() doesn't manage SPLICE_F_MORE correctly[1] - and, as a result, it incorrectly signals/fails to signal MSG_MORE when splicing to a socket. The problem I'm seeing happens when a short splice occurs because we got a short read due to hitting the EOF on a file: as the length read (read_len) is less than the remaining size to be spliced (len), SPLICE_F_MORE (and thus MSG_MORE) is set. The issue is that, for the moment, we have no way to know *why* the short read occurred and so can't make a good decision on whether we *should* keep MSG_MORE set. MSG_SENDPAGE_NOTLAST was added to work around this, but that is also set incorrectly under some circumstances - for example if a short read fills a single pipe_buffer, but the next read would return more (seqfile can do this). This was observed with the multi_chunk_sendfile tests in the tls kselftest program. Some of those tests would hang and time out when the last chunk of file was less than the sendfile request size: build/kselftest/net/tls -r tls.12_aes_gcm.multi_chunk_sendfile This has been observed before[2] and worked around in AF_TLS[3]. Fix this by making splice_direct_to_actor() always signal SPLICE_F_MORE if we haven't yet hit the requested operation size. SPLICE_F_MORE remains signalled if the user passed it in to splice() but otherwise gets cleared when we've read sufficient data to fulfill the request. If, however, we get a premature EOF from ->splice_read(), have sent at least one byte and SPLICE_F_MORE was not set by the caller, ->splice_eof() will be invoked. Signed-off-by:
