2023-04-19Revert "net/mlx5: Enable management PF initialization"Jakub Kicinski
This reverts commit fe998a3c77b9f989a30a2a01fb00d3729a6d53a4. Paul reports that it causes a regression with IB on CX4 and FW 12.18.1000. In addition I think that the concept of "management PF" is not fully accepted and requires a discussion.

2023-04-19Merge branch 'another-crack-at-a-handshake-upcall-mechanism'Jakub Kicinski
Chuck Lever says: ==================== Another crack at a handshake upcall mechanism Here is v10 of a series to add generic support for transport layer security handshake on behalf of kernel socket consumers (user space consumers use a security library directly, of course). A summary of the purpose of these patches is archived here: https://lore.kernel.org/netdev/1DE06BB1-6BA9-4DB4-B2AA-07DE532963D6@oracle.com/ The first patch in the series applies to the top-level .gitignore file to address the build warnings reported a few days ago. I intend to submit that separately. I'd like you to consider taking the rest of this series for v6.4. The full patch set to support SunRPC with TLSv1.3 is available in the topic-rpc-with-tls-upcall branch here, based on net-next/main: https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git This patch set includes support for in-transit confidentiality and peer authentication for both the Linux NFS client and server. A user space handshake agent for TLSv1.3 to go along with the kernel patches is available in the "main" branch here: https://github.com/oracle/ktls-utils ==================== Link: https://lore.kernel.org/r/168174169259.9520.1911007910797225963.stgit@91.116.238.104.host.secureserver.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-04-19net/handshake: Create a NETLINK service for handling handshake requestsChuck Lever
When a kernel consumer needs a transport layer security session, it first needs a handshake to negotiate and establish a session. This negotiation can be done in user space via one of the several existing library implementations, or it can be done in the kernel. No in-kernel handshake implementations yet exist. In their absence, we add a netlink service that can: a. Notify a user space daemon that a handshake is needed. b. Once notified, the daemon calls the kernel back via this netlink service to get the handshake parameters, including an open socket on which to establish the session. c. Once the handshake is complete, the daemon reports the session status and other information via a second netlink operation. This operation marks that it is safe for the kernel to use the open socket and the security session established there. The notification service uses a multicast group. Each handshake mechanism (eg, tlshd) adopts its own group number so that the handshake services are completely independent of one another. The kernel can then tell via netlink_has_listeners() whether a handshake service is active and prepared to handle a handshake request. A new netlink operation, ACCEPT, acts like accept(2) in that it instantiates a file descriptor in the user space daemon's fd table. If this operation is successful, the reply carries the fd number, which can be treated as an open and ready file descriptor. While user space is performing the handshake, the kernel keeps its muddy paws off the open socket. A second new netlink operation, DONE, indicates that the user space daemon is finished with the socket and it is safe for the kernel to use again. The operation also indicates whether a session was established successfully. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

There are two variants of the MT7531 switch IC which got different features (and pins) regarding port 5: * MT7531AE: SGMII/1000Base-X/2500Base-X SerDes PCS * MT7531BE: RGMII Moving the creation of the SerDes PCS from mt753x_setup to mt7530_probe with commit 6de285229773 ("net: dsa: mt7530: move SGMII PCS creation to mt7530_probe function") works fine for MT7531AE which got two instances of mtk-pcs-lynxi, however, MT7531BE requires mt7531_pll_setup to setup clocks before the single PCS on port 6 (usually used as CPU port) starts to work and hence the PCS creation failed on MT7531BE. Fix this by introducing a pointer to mt7531_create_sgmii function in struct mt7530_priv and call it again at the end of mt753x_setup like it was before commit 6de285229773 ("net: dsa: mt7530: move SGMII PCS creation to mt7530_probe function").

2023-04-19module: add debugging auto-load duplicate module supportLuis Chamberlain
The finit_module() system call can in the worst case use up to more than twice of a module's size in virtual memory. Duplicate finit_module() system calls are non fatal, however they unnecessarily strain virtual memory during bootup and in the worst case can cause a system to fail to boot. This is only known to currently be an issue on systems with larger number of CPUs. To help debug this situation we need to consider the different sources for finit_module(). Requests from the kernel that rely on module auto-loading, ie, the kernel's *request_module() API, are one source of calls. Although modprobe checks to see if a module is already loaded prior to calling finit_module() there is a small race possible allowing userspace to trigger multiple modprobe calls racing against modprobe and this not seeing the module yet loaded. This adds debugging support to the kernel module auto-loader (*request_module() calls) to easily detect duplicate module requests. To aid with possible bootup failure issues incurred by this, it will converge duplicates requests to a single request. This avoids any possible strain on virtual memory during bootup which could be incurred by duplicate module autoloading requests. Folks debugging virtual memory abuse on bootup can and should enable this to see what pr_warn()s come on, to see if module auto-loading is to blame for their wores. If they see duplicates they can further debug this by enabling the module.enable_dups_trace kernel parameter or by enabling CONFIG_MODULE_DEBUG_AUTOLOAD_DUPS_TRACE. Current evidence seems to point to only a few duplicates for module auto-loading. And so the source for other duplicates creating heavy virtual memory pressure due to larger number of CPUs should becoming from another place (likely udev).

Use a single line for uli_exclude_device(). Add uli_exclude_device() prototype in ppc-pci.h and guard it. Remove that prototype from mpc85xx_ds.c and mpc86xx_hpcn.c files. Make uli_pirq_to_irq[] static as it is used only in that file.

2023-04-19SUNRPC: remove the maximum number of retries in call_bind_statusDai Ngo
Currently call_bind_status places a hard limit of 3 to the number of retries on EACCES error. This limit was done to prevent NLM unlock requests from being hang forever when the server keeps returning garbage. However this change causes problem for cases when NLM service takes longer than 9 seconds to register with the port mapper after a restart. This patch removes this hard coded limit and let the RPC handles the retry based on the standard hard/soft task semantics.

2023-04-19rpmsg: glink: Propagate TX failures in intentless mode as wellBjorn Andersson
As support for splitting transmission over several messages using TX_DATA_CONT was introduced it does not immediately return the return value of qcom_glink_tx(). The result is that in the intentless case (i.e. intent == NULL), the code will continue to send all additional chunks. This is wasteful, and it's possible that the send operation could incorrectly indicate success, if the last chunk fits in the TX fifo. Fix the condition.

2023-04-19rpmsg: glink: Wait for intent, not just request ackBjorn Andersson
In some implementations of the remote firmware, an intent request acknowledgment is sent when it's determined if the intent allocation will be fulfilled, but then the intent is queued after the acknowledgment. The result is that upon receiving a granted allocation request, the search for the newly allocated intent will fail and an additional request will be made. This will at best waste memory, but if the second request is rejected the transaction will be incorrectly rejected. Take the incoming intent into account in the wait to mitigate this problem. The above scenario can still happen, in the case that, on that same channel, an unrelated intent is delivered prior to the request acknowledgment and a separate process enters the send path and picks up the intent. Given that there's no relationship between the acknowledgment and the delivered (or to be delivered intent), there doesn't seem to be a solution to this problem.
