2024-08-13bcachefs: Convert for_each_btree_node() to lockrestart_do()Kent Overstreet
for_each_btree_node() now works similarly to for_each_btree_key(), where the loop body is passed as an argument to be passed to lockrestart_do(). This now calls trans_begin() on every loop iteration - which fixes an SRCU warning in backpointers fsck. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-08-13bcachefs: delete faulty fastpath in bch2_btree_path_traverse_cached()Kent Overstreet
bch2_btree_path_traverse_cached() was previously checking if it could just relock the path, which is a common idiom in path traversal. However, it was using btree_node_relock(), not btree_path_relock(); btree_path_relock() only succeeds if the path was in state BTREE_ITER_NEED_RELOCK. If the path was in state BTREE_ITER_NEED_TRAVERSE a full traversal is needed; this led to a null ptr deref in bch2_btree_path_traverse_cached(). And the short circuit check here isn't needed, since it was already done in the main bch2_btree_path_traverse_one(). Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-08-13net: netconsole: Constify struct config_item_typeChristophe JAILLET
'struct config_item_type' is not modified in this driver. This structure is only used with config_group_init_type_name() which takes a const struct config_item_type* as a 3rd argument. This also makes things consistent with 'netconsole_target_type' witch is already const.

On little-endian systems, doing subtraction after htons() leads to interesting results: Given: MAGIC_BYTES = 123 = 0x007B aka. in big endian: 0x7B00 = 31488 sizeof(struct iphdr) = 20 Before this patch: __bpf_constant_htons(MAGIC_BYTES) - sizeof(struct iphdr) = 0x7AEC 0x7AEC = htons(0xEC7A) = htons(60538) So these were outer IP packets with a total length of 123 bytes, containing an inner IP packet with a total length of 60538 bytes. After this patch: __bpf_constant_htons(MAGIC_BYTES - sizeof(struct iphdr)) = htons(103) Now these packets are outer IP packets with a total length of 123 bytes, containing an inner IP packet with a total length of 103 bytes.

2024-08-13iavf: add support for offloading tc U32 cls filtersAhmed Zaki
Add support for offloading cls U32 filters. Only "skbedit queue_mapping" and "drop" actions are supported. Also, only "ip" and "802_3" tc protocols are allowed. The PF must advertise the VIRTCHNL_VF_OFFLOAD_TC_U32 capability flag. Since the filters will be enabled via the FD stage at the PF, a new type of FDIR filters is added and the existing list and state machine are used. The new filters can be used to configure flow directors based on raw (binary) pattern in the rx packet. Examples: 0. # tc qdisc add dev enp175s0v0 ingress 1. Redirect UDP from src IP 192.168.2.1 to queue 12: # tc filter add dev <dev> protocol ip ingress u32 \ match u32 0x45000000 0xff000000 at 0 \ match u32 0x00110000 0x00ff0000 at 8 \ match u32 0xC0A80201 0xffffffff at 12 \ match u32 0x00000000 0x00000000 at 24 \ action skbedit queue_mapping 12 skip_sw 2. Drop all ICMP: # tc filter add dev <dev> protocol ip ingress u32 \ match u32 0x45000000 0xff000000 at 0 \ match u32 0x00010000 0x00ff0000 at 8 \ match u32 0x00000000 0x00000000 at 24 \ action drop skip_sw 3. Redirect ICMP traffic from MAC 3c:fd:fe:a5:47:e0 to queue 7 (note proto: 802_3): # tc filter add dev <dev> protocol 802_3 ingress u32 \ match u32 0x00003CFD 0x0000ffff at 4 \ match u32 0xFEA547E0 0xffffffff at 8 \ match u32 0x08004500 0xffffff00 at 12 \ match u32 0x00000001 0x000000ff at 20 \ match u32 0x0000 0x0000 at 40 \ action skbedit queue_mapping 7 skip_sw Notes on matches: 1 - All intermediate fields that are needed to parse the correct PTYPE must be provided (in e.g. 3: Ethernet Type 0x0800 in MAC, IP version and IP length: 0x45 and protocol: 0x01 (ICMP)). 2 - The last match must provide an offset that guarantees all required headers are accounted for, even if the last header is not matched. For example, in #2, the last match is 4 bytes at offset 24 starting from IP header, so the total is 14 (MAC) + 24 + 4 = 42, which is the sum of MAC+IP+ICMP headers.

2024-08-13iavf: refactor add/del FDIR filtersAhmed Zaki
In preparation for a second type of FDIR filters that can be added by tc-u32, move the add/del of the FDIR logic to be entirely contained in iavf_fdir.c. The iavf_find_fdir_fltr_by_loc() is renamed to iavf_find_fdir_fltr() to be more agnostic to the filter ID parameter (for now @loc, which is relevant only to current FDIR filters added via ethtool). The FDIR filter deletion is moved from iavf_del_fdir_ethtool() in ethtool.c to iavf_fdir_del_fltr(). While at it, fix a minor bug where the "fltr" is accessed out of the fdir_fltr_lock spinlock protection.

2024-08-13exec: Fix ToCToU between perm check and set-uid/gid usageKees Cook
When opening a file for exec via do_filp_open(), permission checking is done against the file's metadata at that moment, and on success, a file pointer is passed back. Much later in the execve() code path, the file metadata (specifically mode, uid, and gid) is used to determine if/how to set the uid and gid. However, those values may have changed since the permissions check, meaning the execution may gain unintended privileges. For example, if a file could change permissions from executable and not set-id: ---------x 1 root root 16048 Aug 7 13:16 target to set-id and non-executable: ---S------ 1 root root 16048 Aug 7 13:16 target it is possible to gain root privileges when execution should have been disallowed. While this race condition is rare in real-world scenarios, it has been observed (and proven exploitable) when package managers are updating the setuid bits of installed programs. Such files start with being world-executable but then are adjusted to be group-exec with a set-uid bit. For example, "chmod o-x,u+s target" makes "target" executable only by uid "root" and gid "cdrom", while also becoming setuid-root: -rwxr-xr-x 1 root cdrom 16048 Aug 7 13:16 target becomes: -rwsr-xr-- 1 root cdrom 16048 Aug 7 13:16 target But racing the chmod means users without group "cdrom" membership can get the permission to execute "target" just before the chmod, and when the chmod finishes, the exec reaches brpm_fill_uid(), and performs the setuid to root, violating the expressed authorization of "only cdrom group members can setuid to root". Re-check that we still have execute permissions in case the metadata has changed. It would be better to keep a copy from the perm-check time, but until we can do that refactoring, the least-bad option is to do a full inode_permission() call (under inode lock). It is understood that this is safe against dead-locks, but hardly optimal.

2024-08-13dm persistent data: fix memory allocation failureMikulas Patocka
kmalloc is unreliable when allocating more than 8 pages of memory. It may fail when there is plenty of free memory but the memory is fragmented. Zdenek Kabelac observed such failure in his tests. This commit changes kmalloc to kvmalloc - kvmalloc will fall back to vmalloc if the large allocation fails.

2024-08-13perf/bpf: Don't call bpf_overflow_handler() for tracing eventsKyle Huey
The regressing commit is new in 6.10. It assumed that anytime event->prog is set bpf_overflow_handler() should be invoked to execute the attached bpf program. This assumption is false for tracing events, and as a result the regressing commit broke bpftrace by invoking the bpf handler with garbage inputs on overflow. Prior to the regression the overflow handlers formed a chain (of length 0, 1, or 2) and perf_event_set_bpf_handler() (the !tracing case) added bpf_overflow_handler() to that chain, while perf_event_attach_bpf_prog() (the tracing case) did not. Both set event->prog. The chain of overflow handlers was replaced by a single overflow handler slot and a fixed call to bpf_overflow_handler() when appropriate. This modifies the condition there to check event->prog->type == BPF_PROG_TYPE_PERF_EVENT, restoring the previous behavior and fixing bpftrace.
