2023-10-30Merge tag 'vfs-6.7.xattr' of ↵Linus Torvalds
gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs Pull vfs xattr updates from Christian Brauner: "The 's_xattr' field of 'struct super_block' currently requires a mutable table of 'struct xattr_handler' entries (although each handler itself is const). However, no code in vfs actually modifies the tables. This changes the type of 's_xattr' to allow const tables, and modifies existing file systems to move their tables to .rodata. This is desirable because these tables contain entries with function pointers in them; moving them to .rodata makes it considerably less likely to be modified accidentally or maliciously at runtime" * tag 'vfs-6.7.xattr' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs: (30 commits) const_structs.checkpatch: add xattr_handler net: move sockfs_xattr_handlers to .rodata shmem: move shmem_xattr_handlers to .rodata overlayfs: move xattr tables to .rodata xfs: move xfs_xattr_handlers to .rodata ubifs: move ubifs_xattr_handlers to .rodata squashfs: move squashfs_xattr_handlers to .rodata smb: move cifs_xattr_handlers to .rodata reiserfs: move reiserfs_xattr_handlers to .rodata orangefs: move orangefs_xattr_handlers to .rodata ocfs2: move ocfs2_xattr_handlers and ocfs2_xattr_handler_map to .rodata ntfs3: move ntfs_xattr_handlers to .rodata nfs: move nfs4_xattr_handlers to .rodata kernfs: move kernfs_xattr_handlers to .rodata jfs: move jfs_xattr_handlers to .rodata jffs2: move jffs2_xattr_handlers to .rodata hfsplus: move hfsplus_xattr_handlers to .rodata hfs: move hfs_xattr_handlers to .rodata gfs2: move gfs2_xattr_handlers_max to .rodata fuse: move fuse_xattr_handlers to .rodata ...

It uses function pointers, but they get optimised away - Move the check for ->copy_mc to _copy_from_iter() and copy_page_from_iter_atomic() rather than in memcpy_from_iter_mc() where it gets repeated for every segment. Instead, we check once and invoke a side function that can use iterate_bvec() rather than iterate_and_advance() and supply a different step function - Move the copy-and-csum code to net/ where it can be in proximity with the code that uses it - Fold memcpy_and_csum() in to its two users - Move csum_and_copy_from_iter_full() out of line and merge in csum_and_copy_from_iter() since the former is the only caller of the latter - Move hash_and_copy_to_iter() to net/ where it can be with its only caller" * tag 'vfs-6.7.iov_iter' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs: iov_iter, net: Move hash_and_copy_to_iter() to net/ iov_iter, net: Merge csum_and_copy_from_iter{,_full}() together iov_iter, net: Fold in csum_and_memcpy() iov_iter, net: Move csum_and_copy_to/from_iter() to net/ iov_iter: Don't deal with iter->copy_mc in memcpy_from_iter_mc() iov_iter: Convert iterate*() to inline funcs iov_iter: Derive user-backedness from the iterator type iov_iter: Renumber ITER_* constants infiniband: Use user_backed_iter() to see if iterator is UBUF/IOVEC sound: Fix snd_pcm_readv()/writev() to use iov access functions iov_iter, x86: Be consistent about the __user tag on copy_mc_to_user() iov_iter: Remove last_offset from iov_iter as it was for ITER_PIPE

Derive the net device from the ifindex specified in the ancillary header and invoke its MDB get NDO. Note that unlike other get handlers, the allocation of the skb containing the response is not performed in the common rtnetlink code as the size is variable and needs to be determined by the respective driver.

2023-10-27bridge: mcast: Dump MDB entries even when snooping is disabledIdo Schimmel
Currently, the bridge driver does not dump MDB entries when multicast snooping is disabled although the entries are present in the kernel: # bridge mdb add dev br0 port swp1 grp 239.1.1.1 permanent # bridge mdb show dev br0 dev br0 port swp1 grp 239.1.1.1 permanent dev br0 port br0 grp ff02::6a temp dev br0 port br0 grp ff02::1:ff9d:e61b temp # ip link set dev br0 type bridge mcast_snooping 0 # bridge mdb show dev br0 # ip link set dev br0 type bridge mcast_snooping 1 # bridge mdb show dev br0 dev br0 port swp1 grp 239.1.1.1 permanent dev br0 port br0 grp ff02::6a temp dev br0 port br0 grp ff02::1:ff9d:e61b temp This behavior differs from other netlink dump interfaces that dump entries regardless if they are used or not. For example, VLANs are dumped even when VLAN filtering is disabled: # ip link set dev br0 type bridge vlan_filtering 0 # bridge vlan show dev swp1 port vlan-id swp1 1 PVID Egress Untagged Remove the check and always dump MDB entries: # bridge mdb add dev br0 port swp1 grp 239.1.1.1 permanent # bridge mdb show dev br0 dev br0 port swp1 grp 239.1.1.1 permanent dev br0 port br0 grp ff02::6a temp dev br0 port br0 grp ff02::1:ffeb:1a4d temp # ip link set dev br0 type bridge mcast_snooping 0 # bridge mdb show dev br0 dev br0 port swp1 grp 239.1.1.1 permanent dev br0 port br0 grp ff02::6a temp dev br0 port br0 grp ff02::1:ffeb:1a4d temp # ip link set dev br0 type bridge mcast_snooping 1 # bridge mdb show dev br0 dev br0 port swp1 grp 239.1.1.1 permanent dev br0 port br0 grp ff02::6a temp dev br0 port br0 grp ff02::1:ffeb:1a4d temp Signed-off-by: Ido Schimmel <idosch@nvidia.com> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: David S.

2023-10-27net/tcp: Wire up l3index to TCP-AODmitry Safonov
Similarly how TCP_MD5SIG_FLAG_IFINDEX works for TCP-MD5, TCP_AO_KEYF_IFINDEX is an AO-key flag that binds that MKT to a specified by L3 ifinndex. Similarly, without this flag the key will work in the default VRF l3index = 0 for connections. To prevent AO-keys from overlapping, it's restricted to add key B for a socket that has key A, which have the same sndid/rcvid and one of the following is true: - !(A.keyflags & TCP_AO_KEYF_IFINDEX) or !(B.keyflags & TCP_AO_KEYF_IFINDEX) so that any key is non-bound to a VRF - A.l3index == B.l3index both want to work for the same VRF Additionally, it's restricted to match TCP-MD5 keys for the same peer the following way: |--------------|--------------------|----------------|---------------| | | MD5 key without | MD5 key | MD5 key | | | l3index | l3index=0 | l3index=N | |--------------|--------------------|----------------|---------------| | TCP-AO key | | | | | without | reject | reject | reject | | l3index | | | | |--------------|--------------------|----------------|---------------| | TCP-AO key | | | | | l3index=0 | reject | reject | allow | |--------------|--------------------|----------------|---------------| | TCP-AO key | | | | | l3index=N | reject | allow | reject | |--------------|--------------------|----------------|---------------| This is done with the help of tcp_md5_do_lookup_any_l3index() to reject adding AO key without TCP_AO_KEYF_IFINDEX if there's TCP-MD5 in any VRF. This is important for case where sysctl_tcp_l3mdev_accept = 1 Similarly, for TCP-AO lookups tcp_ao_do_lookup() may be used with l3index < 0, so that __tcp_ao_key_cmp() will match TCP-AO key in any VRF.

Similarly to TCP-MD5, add a static key to TCP-AO that is patched out when there are no keys on a machine and dynamically enabled with the first setsockopt(TCP_AO) adds a key on any socket. The static key is as well dynamically disabled later when the socket is destructed. The lifetime of enabled static key here is the same as ao_info: it is enabled on allocation, passed over from full socket to twsk and destructed when ao_info is scheduled for destruction.

2023-10-27net/tcp: Allow asynchronous delete for TCP-AO keys (MKTs)Dmitry Safonov
Delete becomes very, very fast - almost free, but after setsockopt() syscall returns, the key is still alive until next RCU grace period. Which is fine for listen sockets as userspace needs to be aware of setsockopt(TCP_AO) and accept() race and resolve it with verification by getsockopt() after TCP connection was accepted. The benchmark results (on non-loaded box, worse with more RCU work pending): > ok 33 Worst case delete 16384 keys: min=5ms max=10ms mean=6.93904ms stddev=0.263421 > ok 34 Add a new key 16384 keys: min=1ms max=4ms mean=2.17751ms stddev=0.147564 > ok 35 Remove random-search 16384 keys: min=5ms max=10ms mean=6.50243ms stddev=0.254999 > ok 36 Remove async 16384 keys: min=0ms max=0ms mean=0.0296107ms stddev=0.0172078 Co-developed-by: Francesco Ruggeri <fruggeri@arista.com> Signed-off-by: Francesco Ruggeri <fruggeri@arista.com> Co-developed-by: Salam Noureddine <noureddine@arista.com> Signed-off-by: Salam Noureddine <noureddine@arista.com> Signed-off-by: Dmitry Safonov <dima@arista.com> Acked-by: David Ahern <dsahern@kernel.org> Signed-off-by: David S.

2023-10-27net/tcp: Add TCP-AO sign to outgoing packetsDmitry Safonov
Using precalculated traffic keys, sign TCP segments as prescribed by RFC5925. Per RFC, TCP header options are included in sign calculation: "The TCP header, by default including options, and where the TCP checksum and TCP-AO MAC fields are set to zero, all in network- byte order." (5.1.3) tcp_ao_hash_header() has exclude_options parameter to optionally exclude TCP header from hash calculation, as described in RFC5925 (9.1), this is needed for interaction with middleboxes that may change "some TCP options". This is wired up to AO key flags and setsockopt() later. Similarly to TCP-MD5 hash TCP segment fragments. From this moment a user can start sending TCP-AO signed segments with one of crypto ahash algorithms from supported by Linux kernel. It can have a user-specified MAC length, to either save TCP option header space or provide higher protection using a longer signature. The inbound segments are not yet verified, TCP-AO option is ignored and they are accepted.

Be as conservative as possible: if there is TCP-MD5 key for a given peer regardless of L3 interface - don't allow setting TCP-AO key for the same peer. According to RFC5925, TCP-AO is supposed to replace TCP-MD5 and there can't be any switch between both on any connected tuple. Later it can be relaxed, if there's a use, but in the beginning restrict any intersection. Note: it's still should be possible to set both TCP-MD5 and TCP-AO keys on a listening socket for *different* peers.

TCP_AO_INFO to change flags, Current_key/RNext_key on a TCP-AO sk Userspace has to introduce keys on every socket it wants to use TCP-AO option on, similarly to TCP_MD5SIG/TCP_MD5SIG_EXT. RFC5925 prohibits definition of MKTs that would match the same peer, so do sanity checks on the data provided by userspace. Be as conservative as possible, including refusal of defining MKT on an established connection with no AO, removing the key in-use and etc. (1) and (2) are to be used by userspace key manager to add/remove keys. (3) main purpose is to set RNext_key, which (as prescribed by RFC5925) is the KeyID that will be requested in TCP-AO header from the peer to sign their segments with.

2023-10-27net/tcp: Prepare tcp_md5sig_pool for TCP-AODmitry Safonov
TCP-AO, similarly to TCP-MD5, needs to allocate tfms on a slow-path, which is setsockopt() and use crypto ahash requests on fast paths, which are RX/TX softirqs. Also, it needs a temporary/scratch buffer for preparing the hash. Rework tcp_md5sig_pool in order to support other hashing algorithms than MD5. It will make it possible to share pre-allocated crypto_ahash descriptors and scratch area between all TCP hash users. Internally tcp_sigpool calls crypto_clone_ahash() API over pre-allocated crypto ahash tfm. Kudos to Herbert, who provided this new crypto API. I was a little concerned over GFP_ATOMIC allocations of ahash and crypto_request in RX/TX (see tcp_sigpool_start()), so I benchmarked both "backends" with different algorithms, using patched version of iperf3[2]. On my laptop with i7-7600U @ 2.80GHz: clone-tfm per-CPU-requests TCP-MD5 2.25 Gbits/sec 2.30 Gbits/sec TCP-AO(hmac(sha1)) 2.53 Gbits/sec 2.54 Gbits/sec TCP-AO(hmac(sha512)) 1.67 Gbits/sec 1.64 Gbits/sec TCP-AO(hmac(sha384)) 1.77 Gbits/sec 1.80 Gbits/sec TCP-AO(hmac(sha224)) 1.29 Gbits/sec 1.30 Gbits/sec TCP-AO(hmac(sha3-512)) 481 Mbits/sec 480 Mbits/sec TCP-AO(hmac(md5)) 2.07 Gbits/sec 2.12 Gbits/sec TCP-AO(hmac(rmd160)) 1.01 Gbits/sec 995 Mbits/sec TCP-AO(cmac(aes128)) [not supporetd yet] 2.11 Gbits/sec So, it seems that my concerns don't have strong grounds and per-CPU crypto_request allocation can be dropped/removed from tcp_sigpool once ciphers get crypto_clone_ahash() support.
