2023-04-14wifi: iwlwifi: mvm: track AP STA pointer and use it for MFPJohannes Berg
Instead of relying on the AP STA ID and dereferencing our firmware -> mac80211 STA array when we really only need the STA, not the per-link information (and might not have it, e.g. for a pairwise key installation where this is relevant), keep track of the AP STA as a pointer to the mac80211 STA, protected by the mutex. Then use it here in the key code instead.

2023-04-14wifi: iwlwifi: pcie: Fix integer overflow in iwl_write_to_user_bufHyunwoo Kim
An integer overflow occurs in the iwl_write_to_user_buf() function, which is called by the iwl_dbgfs_monitor_data_read() function. static bool iwl_write_to_user_buf(char __user *user_buf, ssize_t count, void *buf, ssize_t *size, ssize_t *bytes_copied) { int buf_size_left = count - *bytes_copied; buf_size_left = buf_size_left - (buf_size_left % sizeof(u32)); if (*size > buf_size_left) *size = buf_size_left; If the user passes a SIZE_MAX value to the "ssize_t count" parameter, the ssize_t count parameter is assigned to "int buf_size_left". Then compare "*size" with "buf_size_left" . Here, "buf_size_left" is a negative number, so "*size" is assigned "buf_size_left" and goes into the third argument of the copy_to_user function, causing a heap overflow. This is not a security vulnerability because iwl_dbgfs_monitor_data_read() is a debugfs operation with 0400 privileges.

2023-04-14wifi: iwlwifi: pcie: work around ROM bug on AX210 integratedJohannes Berg
On 22000 and AX210 devices, there's a ROM bug that causes it to set invalid LTR settings. On 22000 and AX210 non-integrated we can fix up these settings from the driver (as done in the code here), but on AX210 integrated these registers are not available to the driver. Attempt to work around the issue by spinning while the IML is being loaded, the IML will then reprogram the LTR values itself after it's loaded, so only the brief IML load (which the ROM is doing) is affected.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2023-04-11 1) Vlad adds the support for linux bridge multicast offload support Patches #1 through #9 Synopsis Vlad Says: ============== Implement support of bridge multicast offload in mlx5. Handle port object attribute SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED notification to toggle multicast offload and bridge snooping support on bridge. Handle port object SWITCHDEV_OBJ_ID_PORT_MDB notification to attach a bridge port to MDB. Steering architecture Existing offload infrastructure relies on two levels of flow tables - bridge ingress and egress. For multicast offload the architecture is extended with additional layer of per-port multicast replication tables. Such tables filter loopback traffic (so packets are not replicated to their source port) and pop VLAN headers for "untagged" VLANs. The tables are referenced by the MDB rules in egress table. MDB egress rule can point to multiple per-port multicast tables, which causes matching multicast traffic to be replicated to all of them, and, consecutively, to several bridge ports: +--------+--+ +---------------------------------------> Port 1 | | | +-^------+--+ | | | | +-----------------------------------------+ | +---------------------------+ | | EGRESS table | | +--> PORT 1 multicast table | | +----------------------------------+ +-----------------------------------------+ | | +---------------------------+ | | INGRESS table | | | | | | | | +----------------------------------+ | dst_mac=P1,vlan=X -> pop vlan, goto P1 +--+ | | FG0: | | | | | dst_mac=P1,vlan=Y -> pop vlan, goto P1 | | | src_port=dst_port -> drop | | | src_mac=M1,vlan=X -> goto egress +---> dst_mac=P2,vlan=X -> pop vlan, goto P2 +--+ | | FG1: | | | ... | | dst_mac=P2,vlan=Y -> goto P2 | | | | VLAN X -> pop, goto port | | | | | dst_mac=MDB1,vlan=Y -> goto mcast P1,P2 +-----+ | ... | | +----------------------------------+ | | | | | VLAN Y -> pop, goto port +-------+ +-----------------------------------------+ | | | FG3: | | | | matchall -> goto port | | | | | | | +---------------------------+ | | | | | | +--------+--+ +---------------------------------------> Port 2 | | | +-^------+--+ | | | | | +---------------------------+ | +--> PORT 2 multicast table | | +---------------------------+ | | | | | FG0: | | | src_port=dst_port -> drop | | | FG1: | | | VLAN X -> pop, goto port | | | ... | | | | | | FG3: | | | matchall -> goto port +-------+ | | +---------------------------+ Patches overview: - Patch 1 adds hardware definition bits for capabilities required to replicate multicast packets to multiple per-port tables. These bits are used by following patches to only attempt multicast offload if firmware and hardware provide necessary support. - Pathces 2-4 patches are preparations and refactoring. - Patch 5 implements necessary infrastructure to toggle multicast offload via SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED port object attribute notification. This also enabled IGMP and MLD snooping. - Patch 6 implements per-port multicast replication tables. It only supports filtering of loopback packets. - Patch 7 extends per-port multicast tables with VLAN pop support for 'untagged' VLANs. - Patch 8 handles SWITCHDEV_OBJ_ID_PORT_MDB port object notifications. It creates MDB replication rules in egress table that can replicate packets to multiple per-port multicast tables. - Patch 9 adds tracepoints for MDB events. ============== 2) Parav Create a new allocation profile for SFs, to save on memory 3) Yevgeny provides some initial patches for upcoming software steering support new pattern/arguments type of modify_header actions. Starting with ConnectX-6 DX, we use a new design of modify_header FW object. The current modify_header object allows for having only limited number of these FW objects, which means that we are limited in the number of offloaded flows that require modify_header action.

PFs which support the MAC Merge layer also have a set of 8 registers called "Port traffic class N frame preemption register (PTC0FPR - PTC7FPR)". Through these, a traffic class (group of TX rings of same dequeue priority) can be mapped to the eMAC or to the pMAC. There's nothing particularly spectacular here. We should probably only commit the preemptible TCs to hardware once the MAC Merge layer became active, but unlike Felix, we don't have an IRQ that notifies us of that. We'd have to sleep for up to verifyTime (127 ms) to wait for a resolution coming from the verification state machine; not only from the ndo_setup_tc() code path, but also from enetc_mm_link_state_update(). Since it's relatively complicated and has a relatively small benefit, I'm not doing it.

The main changes are: 1) Rework BPF verifier log behavior and implement it as a rotating log by default with the option to retain old-style fixed log behavior, from Andrii Nakryiko. 2) Adds support for using {FOU,GUE} encap with an ipip device operating in collect_md mode and add a set of BPF kfuncs for controlling encap params, from Christian Ehrig. 3) Allow BPF programs to detect at load time whether a particular kfunc exists or not, and also add support for this in light skeleton, from Alexei Starovoitov. 4) Optimize hashmap lookups when key size is multiple of 4, from Anton Protopopov. 5) Enable RCU semantics for task BPF kptrs and allow referenced kptr tasks to be stored in BPF maps, from David Vernet. 6) Add support for stashing local BPF kptr into a map value via bpf_kptr_xchg(). This is useful e.g. for rbtree node creation for new cgroups, from Dave Marchevsky. 7) Fix BTF handling of is_int_ptr to skip modifiers to work around tracing issues where a program cannot be attached, from Feng Zhou. 8) Migrate a big portion of test_verifier unit tests over to test_progs -a verifier_* via inline asm to ease {read,debug}ability, from Eduard Zingerman. 9) Several updates to the instruction-set.rst documentation which is subject to future IETF standardization (https://lwn.net/Articles/926882/), from Dave Thaler. 10) Fix BPF verifier in the __reg_bound_offset's 64->32 tnum sub-register known bits information propagation, from Daniel Borkmann. 11) Add skb bitfield compaction work related to BPF with the overall goal to make more of the sk_buff bits optional, from Jakub Kicinski. 12) BPF selftest cleanups for build id extraction which stand on its own from the upcoming integration work of build id into struct file object, from Jiri Olsa. 13) Add fixes and optimizations for xsk descriptor validation and several selftest improvements for xsk sockets, from Kal Conley. 14) Add BPF links for struct_ops and enable switching implementations of BPF TCP cong-ctls under a given name by replacing backing struct_ops map, from Kui-Feng Lee. 15) Remove a misleading BPF verifier env->bypass_spec_v1 check on variable offset stack read as earlier Spectre checks cover this, from Luis Gerhorst. 16) Fix issues in copy_from_user_nofault() for BPF and other tracers to resemble copy_from_user_nmi() from safety PoV, from Florian Lehner and Alexei Starovoitov. 17) Add --json-summary option to test_progs in order for CI tooling to ease parsing of test results, from Manu Bretelle. 18) Batch of improvements and refactoring to prep for upcoming bpf_local_storage conversion to bpf_mem_cache_{alloc,free} allocator, from Martin KaFai Lau. 19) Improve bpftool's visual program dump which produces the control flow graph in a DOT format by adding C source inline annotations, from Quentin Monnet. 20) Fix attaching fentry/fexit/fmod_ret/lsm to modules by extracting the module name from BTF of the target and searching kallsyms of the correct module, from Viktor Malik. 21) Improve BPF verifier handling of '<const> <cond> <non_const>' to better detect whether in particular jmp32 branches are taken, from Yonghong Song. 22) Allow BPF TCP cong-ctls to write app_limited of struct tcp_sock. A built-in cc or one from a kernel module is already able to write to app_limited, from Yixin Shen.
