Allocate memory for the data when it's used. Ideally the struct could be on the stack, but we can't DMA stack memory. With this change only the header and status memory are shared between commands, which will allow using a tighter lock than RTNL.

2024-05-07net: dsa: mt7530: detect PHY muxing when PHY is defined on switch MDIO busArınç ÜNAL1-1/+2
Currently, the MT7530 DSA subdriver configures the MT7530 switch to provide direct access to switch PHYs, meaning, the switch PHYs listen on the MDIO bus the switch listens on. The PHY muxing feature makes use of this. This is problematic as the PHY may be attached before the switch is initialised, in which case, the PHY will fail to be attached. Since commit 91374ba537bd ("net: dsa: mt7530: support OF-based registration of switch MDIO bus"), we can describe the switch PHYs on the MDIO bus of the switch on the device tree. Extend the check to detect PHY muxing when the PHY is defined on the MDIO bus of the switch on the device tree. When the PHY is described this way, the switch will be initialised first, then the switch MDIO bus will be registered. Only after these steps, the PHY will be attached.

2024-05-06octeontx2-pf: Treat truncation of IRQ name as an errorSimon Horman1-2/+10
According to GCC, the constriction of irq_name in otx2_open() may, theoretically, be truncated. This patch takes the approach of treating such a situation as an error which it detects by making use of the return value of snprintf, which is the total number of bytes, excluding the trailing '\0', that would have been written. Based on the approach taken to a similar problem in commit 54b909436ede ("rtc: fix snprintf() checking in is_rtc_hctosys()") Flagged by gcc-13 W=1 builds as: .../otx2_pf.c:1933:58: warning: 'snprintf' output may be truncated before the last format character [-Wformat-truncation=] 1933 | snprintf(irq_name, NAME_SIZE, "%s-rxtx-%d", pf->netdev->name, | ^ .../otx2_pf.c:1933:17: note: 'snprintf' output between 8 and 33 bytes into a destination of size 32 1933 | snprintf(irq_name, NAME_SIZE, "%s-rxtx-%d", pf->netdev->name, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1934 | qidx); | ~~~~~ Compile tested only.

2024-05-07gtp: use IPv6 address /64 prefix for UE/MSPablo Neira Ayuso1-10/+42
Harald Welte reports that according to 3GPP TS 29.060: PDN Connection: the association between a MS represented by one IPv4 address and/or one IPv6 prefix and a PDN represented by an APN. this clearly states that IPv4 is a single address while IPv6 is a single prefix. Then, 3GPP TS 29.061, Section 11.2.1.3: For APNs that are configured for IPv6 address allocation, the GGSN/P-GW shall only use the Prefix part of the IPv6 address for forwarding of mobile terminated IP packets. The size of the prefix shall be according to the maximum prefix length for a global IPv6 address as specified in the IPv6 Addressing Architecture, see RFC 4291 [82]. RFC 4291 section 2.5.4 states All Global Unicast addresses other than those that start with binary 000 have a 64-bit interface ID field (i.e., n + m = 64) ... 3GPP TS 29.61 Section 11.2.1.3.2a: In the procedure in the cases of using GTP-based S5/S8, P-GW acts as an access router, and allocates to a UE a globally unique /64 IPv6 prefix if the PLMN allocates the prefix. Therefore, compare IPv6 address /64 prefix only since MS/UE is not a single address like in the IPv4 case. Reject IPv6 address with EADDRNOTAVAIL if it lower 64 bits of the IPv6 address from the control plane are set. Signed-off-by: Pablo Neira Ayuso <[email protected]>
2024-05-07gtp: add IPv6 supportPablo Neira Ayuso1-27/+369
Add new iflink attributes to configure in-kernel UDP listener socket address: IFLA_GTP_LOCAL and IFLA_GTP_LOCAL6. If none of these attributes are specified, default is still to IPv4 INADDR_ANY for backward compatibility. Add new attributes to set up family and IPv6 address of GTP tunnels: GTPA_FAMILY, GTPA_PEER_ADDR6 and GTPA_MS_ADDR6. If no GTPA_FAMILY is specified, AF_INET is assumed for backward compatibility. setsockopt IPV6_ADDRFORM allows to downgrade socket from IPv6 to IPv4 after socket is bound. Assumption is that socket listener that is attached to the gtp device needs to be either IPv4 or IPv6. Therefore, GTP socket listener does not allow for IPv4-mapped-IPv6 listener.

2024-05-07gtp: properly parse extension headersPablo Neira Ayuso1-0/+41
Currently GTP packets are dropped if the next extension field is set to non-zero value, but this are valid GTP packets. TS 29.281 provides a longer header format, which is defined as struct gtp1_header_long. Such long header format is used if any of the S, PN, E flags is set. This long header is 4 bytes longer than struct gtp1_header, plus variable length (optional) extension headers. The next extension header field is zero is no extension header is provided. The extension header is composed of a length field which includes total number of 4 byte words including the extension header itself (1 byte), payload (variable length) and next type (1 byte). The extension header size and its payload is aligned to 4 bytes. A GTP packet might come with a chain extensions headers, which makes it slightly cumbersome to parse because the extension next header field comes at the end of the extension header, and there is a need to check if this field becomes zero to stop the extension header parser.

2024-05-06wifi: iwlwifi: mvm: Fix race in scan completionIlan Peer4-29/+55
The move of the scan complete notification handling to the wiphy worker introduced a race between scan complete notification and scan abort: - The wiphy lock is held, e.g., for rfkill handling etc. - Scan complete notification is received but not handled yet. - Scan abort is triggered, and scan abort is sent to the FW. Once the scan abort command is sent successfully, the flow synchronously waits for the scan complete notification. However, as the scan complete notification was already received but not processed yet, this hangs for a second and continues leaving the scan status in an inconsistent state. - Once scan complete handling is started (when the wiphy lock is not held) since the scan status is not an inconsistent state, a warning is issued and the scan complete notification is not handled. To fix this issue, switch back the scan complete notification to be asynchronously handling, and only move the link selection logic to a worker (which was the original reason for the move to use wiphy lock). While at it, refactor some prints to improve debug data.

2024-05-06wifi: iwlwifi: mvm: Block EMLSR when a p2p/softAP vif is activeYedidya Benshimol7-19/+133
When there's an active link in a non-station vif, the station vif is not allowed to enter EMLSR Note that blocking EMLSR by calling iwl_mvm_block_esr() we will schedule an exit from EMLSR worker, but the worker cannot run before the activation of the non-BSS link, as ieee80211_remain_on_channel already holds the wiphy mutex. Handle that by explicitly calling ieee80211_set_active_links() to leave EMLSR, and then doing iwl_mvm_block_esr() only for consistency and to avoid re-entering it before ready. Note that a call to ieee80211_set_active_links requires to release the mvm mutex, but that's ok since we still hold the wiphy lock. The only thing that might race here is the ESR_MODE_NOTIF, so this changes its handler to run under the wiphy lock.

2024-05-06wifi: iwlwifi: mvm: exit EMLSR when CSA happensJohannes Berg5-26/+115
If CSA is happening, then exit EMLSR to keep the better link, which is the primary link unless that's doing the CSA with quiet. This is done because we can't transmit the OMN frame on a quiet link, but want to exit EMLSR during CSA for better beacon reception, so we can follow the switch accurately.

2024-05-06wifi: iwlwifi: mvm: avoid always prefering single-linkMiri Korenblit1-2/+2
The new link selection algorithm uses defaults values for BSS load if the BSS Load element was not published by the AP. For 6 GHz, that value is 0. So if the best link is 6 GHz, the EMLSR grade to always be equal to the grade of the best link, and then the best link grade is getting a bonus of 10 percent, meaning that we will never activate EMLSR. Change the logic to not give a bonus for the best link.

2024-05-06wifi: iwlwifi: mvm: trigger link selection upon TTLM start/endMiri Korenblit1-0/+5
When non default TTLM is applied, mac80211 may force us to use a specific link (For example, if the only active link becomes a dormant link, mac80211 will pick the first usable link and set it as active). When default TTLM is applied, we have new usable links that we might want to select. Therefore, trigger MLO scan and link selection upon change in TTLM.
