2023-06-19SUNRPC: Capture CMSG metadata on client-side receiveChuck Lever
kTLS sockets use CMSG to report decryption errors and the need for session re-keying. For RPC-with-TLS, an "application data" message contains a ULP payload, and that is passed along to the RPC client. An "alert" message triggers connection reset. Everything else is discarded.

2023-06-19SUNRPC: Ignore data_ready callbacks during TLS handshakesChuck Lever
The RPC header parser doesn't recognize TLS handshake traffic, so it will close the connection prematurely with an error. To avoid that, shunt the transport's data_ready callback when there is a TLS handshake in progress. The XPRT_SOCK_IGNORE_RECV flag will be toggled by code added in a subsequent patch.

2023-06-19ovl: enable fsnotify events on underlying real filesAmir Goldstein
Overlayfs creates the real underlying files with fake f_path, whose f_inode is on the underlying fs and f_path on overlayfs. Those real files were open with FMODE_NONOTIFY, because fsnotify code was not prapared to handle fsnotify hooks on files with fake path correctly and fanotify would report unexpected event->fd with fake overlayfs path, when the underlying fs was being watched. Teach fsnotify to handle events on the real files, and do not set real files to FMODE_NONOTIFY to allow operations on real file (e.g. open, access, modify, close) to generate async and permission events. Because fsnotify does not have notifications on address space operations, we do not need to worry about ->vm_file not reporting events to a watched overlayfs when users are accessing a mapped overlayfs file.

2023-06-19fs: use backing_file container for internal files with "fake" f_pathAmir Goldstein
Overlayfs uses open_with_fake_path() to allocate internal kernel files, with a "fake" path - whose f_path is not on the same fs as f_inode. Allocate a container struct backing_file for those internal files, that is used to hold the "fake" ovl path along with the real path. backing_file_real_path() can be used to access the stored real path.

2023-06-19SUNRPC: attempt to reach rpcbind with an abstract socket nameNeilBrown
NFS is primarily name-spaced using network namespaces. However it contacts rpcbind (and gss_proxy) using AF_UNIX sockets which are name-spaced using the mount namespaces. This requires a container using NFSv3 (the form that requires rpcbind) to manage both network and mount namespaces, which can seem an unnecessary burden. As NFS is primarily a network service it makes sense to use network namespaces as much as possible, and to prefer to communicate with an rpcbind running in the same network namespace. This can be done, while preserving the benefits of AF_UNIX sockets, by using an abstract socket address. An abstract address has a nul at the start of sun_path, and a length that is exactly the complete size of the sockaddr_un up to the end of the name, NOT including any trailing nul (which is not part of the address). Abstract addresses are local to a network namespace - regular AF_UNIX path names a resolved in the mount namespace ignoring the network namespace. This patch causes rpcb to first try an abstract address before continuing with regular AF_UNIX and then IP addresses. This ensures backwards compatibility. Choosing the name needs some care as the same address will be configured for rpcbind, and needs to be built in to libtirpc for this enhancement to be fully successful. There is no formal standard for choosing abstract addresses. The defacto standard appears to be to use a path name similar to what would be used for a filesystem AF_UNIX address - but with a leading nul. In that case "\0/var/run/rpcbind.sock" seems like the best choice. However at this time /var/run is deprecated in favour of /run, so "\0/run/rpcbind.sock" might be better. Though as we are deliberately moving away from using the filesystem it might seem more sensible to explicitly break the connection and just have "\0rpcbind.socket" using the same name as the systemd unit file.. This patch chooses the second option, which seems least likely to raise objections. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
2023-06-19SUNRPC: support abstract unix socket addressesNeilBrown
An "abtract" address for an AF_UNIX socket start with a nul and can contain any bytes for the given length, but traditionally doesn't contain other nuls. When reported, the leading nul is replaced by '@'. sunrpc currently rejects connections to these addresses and reports them as an empty string. To provide support for future use of these addresses, allow them for outgoing connections and report them more usefully.

2023-06-19btrfs: update i_version in update_dev_timeJeff Layton
When updating the ctime, we also want to update i_version. This is just something I noticed by inspection. There is probably no way to test this today unless you can somehow get to this inode via nfsd. Still, I think it's the right thing to do for consistency's sake. David Sterba's comment: I don't see anything wrong with setting the iversion bit, however I also don't see where this would be useful. Agreed with the consistency, otherwise the time is updated when device super block is wiped or a device initialized, both are big events so missing that due to lack of iversion update seems unlikely.

2023-06-19ipvs: align inner_mac_header for encapsulationTerin Stock
When using encapsulation the original packet's headers are copied to the inner headers. This preserves the space for an inner mac header, which is not used by the inner payloads for the encapsulation types supported by IPVS. If a packet is using GUE or GRE encapsulation and needs to be segmented, flow can be passed to __skb_udp_tunnel_segment() which calculates a negative tunnel header length. A negative tunnel header length causes pskb_may_pull() to fail, dropping the packet. This can be observed by attaching probes to ip_vs_in_hook(), __dev_queue_xmit(), and __skb_udp_tunnel_segment(): perf probe --add '__dev_queue_xmit skb->inner_mac_header \ skb->inner_network_header skb->mac_header skb->network_header' perf probe --add '__skb_udp_tunnel_segment:7 tnl_hlen' perf probe -m ip_vs --add 'ip_vs_in_hook skb->inner_mac_header \ skb->inner_network_header skb->mac_header skb->network_header' These probes the headers and tunnel header length for packets which traverse the IPVS encapsulation path. A TCP packet can be forced into the segmentation path by being smaller than a calculated clamped MSS, but larger than the advertised MSS. probe:ip_vs_in_hook: inner_mac_header=0x0 inner_network_header=0x0 mac_header=0x44 network_header=0x52 probe:ip_vs_in_hook: inner_mac_header=0x44 inner_network_header=0x52 mac_header=0x44 network_header=0x32 probe:dev_queue_xmit: inner_mac_header=0x44 inner_network_header=0x52 mac_header=0x44 network_header=0x32 probe:__skb_udp_tunnel_segment_L7: tnl_hlen=-2 When using veth-based encapsulation, the interfaces are set to be mac-less, which does not preserve space for an inner mac header. This prevents this issue from occurring. In our real-world testing of sending a 32KB file we observed operation time increasing from ~75ms for veth-based encapsulation to over 1.5s using IPVS encapsulation due to retries from dropped packets. This changeset modifies the packet on the encapsulation path in ip_vs_tunnel_xmit() and ip_vs_tunnel_xmit_v6() to remove the inner mac header offset. This fixes UDP segmentation for both encapsulation types, and corrects the inner headers for any IPIP flows that may use it.

2023-06-19tty: serial: imx: fix rs485 rx after txMartin Fuzzey
Since commit 79d0224f6bf2 ("tty: serial: imx: Handle RS485 DE signal active high") RS485 reception no longer works after a transmission. The following scenario shows the problem: 1) Open a port in RS485 mode 2) Receive data from remote (OK) 3) Transmit data to remote (OK) 4) Receive data from remote (Nothing received) In RS485 mode, imx_uart_start_tx() calls imx_uart_stop_rx() and, when the transmission is complete, imx_uart_stop_tx() calls imx_uart_start_rx(). Since the above commit imx_uart_stop_rx() now sets the loopback bit but imx_uart_start_rx() does not clear it causing the hardware to remain in loopback mode and not receive external data. Fix this by moving the existing loopback disable code to a helper function and calling it from imx_uart_start_rx() too.

2023-06-19usb: gadget: function: printer: Replace strlcpy with strscpyAzeem Shaikh
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). Direct replacement is safe here since return value of -errno is used to check for truncation instead of PAGE_SIZE.
