2019-07-18proc/sysctl: add shared variables for range checkMatteo Croce
In the sysctl code the proc_dointvec_minmax() function is often used to validate the user supplied value between an allowed range. This function uses the extra1 and extra2 members from struct ctl_table as minimum and maximum allowed value. On sysctl handler declaration, in every source file there are some readonly variables containing just an integer which address is assigned to the extra1 and extra2 members, so the sysctl range is enforced. The special values 0, 1 and INT_MAX are very often used as range boundary, leading duplication of variables like zero=0, one=1, int_max=INT_MAX in different source files: $ git grep -E '\.extra[12].*&(zero|one|int_max)' |wc -l 248 Add a const int array containing the most commonly used values, some macros to refer more easily to the correct array member, and use them instead of creating a local one for every object file.

2019-07-08ipv6: elide flowlabel check if no exclusive leases existWillem de Bruijn
Processes can request ipv6 flowlabels with cmsg IPV6_FLOWINFO. If not set, by default an autogenerated flowlabel is selected. Explicit flowlabels require a control operation per label plus a datapath check on every connection (every datagram if unconnected). This is particularly expensive on unconnected sockets multiplexing many flows, such as QUIC. In the common case, where no lease is exclusive, the check can be safely elided, as both lease request and check trivially succeed. Indeed, autoflowlabel does the same even with exclusive leases. Elide the check if no process has requested an exclusive lease. fl6_sock_lookup previously returns either a reference to a lease or NULL to denote failure. Modify to return a real error and update all callers. On return NULL, they can use the label and will elide the atomic_dec in fl6_sock_release. This is an optimization. Robust applications still have to revert to requesting leases if the fast path fails due to an exclusive lease. Changes RFC->v1: - use static_key_false_deferred to rate limit jump label operations - call static_key_deferred_flush to stop timers on exit - move decrement out of RCU context - defer optimization also if opt data is associated with a lease - updated all fp6_sock_lookup callers, not just udp Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

2019-07-03sctp: count data bundling sack chunk for outctrlchunksXin Long
Now all ctrl chunks are counted for asoc stats.octrlchunks and net SCTP_MIB_OUTCTRLCHUNKS either after queuing up or bundling, other than the chunk maked and bundled in sctp_packet_bundle_sack, which caused 'outctrlchunks' not consistent with 'inctrlchunks' in peer. This issue exists since very beginning, here to fix it by increasing both net SCTP_MIB_OUTCTRLCHUNKS and asoc stats.octrlchunks when sack chunk is maked and bundled in sctp_packet_bundle_sack.

2019-07-01sctp: fix error handling on stream scheduler initializationMarcelo Ricardo Leitner
It allocates the extended area for outbound streams only on sendmsg calls, if they are not yet allocated. When using the priority stream scheduler, this initialization may imply into a subsequent allocation, which may fail. In this case, it was aborting the stream scheduler initialization but leaving the ->ext pointer (allocated) in there, thus in a partially initialized state. On a subsequent call to sendmsg, it would notice the ->ext pointer in there, and trip on uninitialized stuff when trying to schedule the data chunk. The fix is undo the ->ext initialization if the stream scheduler initialization fails and avoid the partially initialized state. Although syzkaller bisected this to commit 4ff40b86262b ("sctp: set chunk transport correctly when it's a new asoc"), this bug was actually introduced on the commit I marked below.

2019-06-29sctp: not bind the socket in sctp_connectXin Long
Now when sctp_connect() is called with a wrong sa_family, it binds to a port but doesn't set bp->port, then sctp_get_af_specific will return NULL and sctp_connect() returns -EINVAL. Then if sctp_bind() is called to bind to another port, the last port it has bound will leak due to bp->port is NULL by then. sctp_connect() doesn't need to bind ports, as later __sctp_connect will do it if bp->port is NULL. So remove it from sctp_connect(). While at it, remove the unnecessary sockaddr.sa_family len check as it's already done in sctp_inet_connect.

Besides, sctp_do_sm() was called recursively, which is not expected. Vlad tried to fix this recursive call in Commit c0786693404c ("sctp: Fix oops when sending queued ASCONF chunks") by introducing a new command SCTP_CMD_SEND_NEXT_ASCONF. But it didn't work as this command is still used in the first sctp_do_sm() call, and sctp_primitive_ASCONF() will be called in this command again. To avoid calling sctp_do_sm() recursively, we send the next queued ASCONF not by sctp_primitive_ASCONF(), but by sctp_sf_do_prm_asconf() in the 1st sctp_do_sm() directly.

2019-04-25crypto: shash - remove shash_desc::flagsEric Biggers
The flags field in 'struct shash_desc' never actually does anything. The only ostensibly supported flag is CRYPTO_TFM_REQ_MAY_SLEEP. However, no shash algorithm ever sleeps, making this flag a no-op. With this being the case, inevitably some users who can't sleep wrongly pass MAY_SLEEP. These would all need to be fixed if any shash algorithm actually started sleeping. For example, the shash_ahash_*() functions, which wrap a shash algorithm with the ahash API, pass through MAY_SLEEP from the ahash API to the shash API. However, the shash functions are called under kmap_atomic(), so actually they're assumed to never sleep. Even if it turns out that some users do need preemption points while hashing large buffers, we could easily provide a helper function crypto_shash_update_large() which divides the data into smaller chunks and calls crypto_shash_update() and cond_resched() for each chunk. It's not necessary to have a flag in 'struct shash_desc', nor is it necessary to make individual shash algorithms aware of this at all. Therefore, remove shash_desc::flags, and document that the crypto_shash_*() functions can be called from any context.

2019-04-19net: rework SIOCGSTAMP ioctl handlingArnd Bergmann
The SIOCGSTAMP/SIOCGSTAMPNS ioctl commands are implemented by many socket protocol handlers, and all of those end up calling the same sock_get_timestamp()/sock_get_timestampns() helper functions, which results in a lot of duplicate code. With the introduction of 64-bit time_t on 32-bit architectures, this gets worse, as we then need four different ioctl commands in each socket protocol implementation. To simplify that, let's add a new .gettstamp() operation in struct proto_ops, and move ioctl implementation into the common sock_ioctl()/compat_sock_ioctl_trans() functions that these all go through. We can reuse the sock_get_timestamp() implementation, but generalize it so it can deal with both native and compat mode, as well as timeval and timespec structures.

sk_forward_alloc's updating is also done on rx path, but to be consistent we change to use sk_mem_charge() in sctp_skb_set_owner_r(). In sctp_eat_data(), it's not enough to check sctp_memory_pressure only, which doesn't work for mem_cgroup_sockets_enabled, so we change to use sk_under_memory_pressure(). When it's under memory pressure, sk_mem_reclaim() and sk_rmem_schedule() should be called on both RENEGE or CHUNK DELIVERY path exit the memory pressure status as soon as possible. Note that sk_rmem_schedule() is using datalen to make things easy there.

2019-04-15sctp: implement memory accounting on tx pathXin Long
Now when sending packets, sk_mem_charge() and sk_mem_uncharge() have been used to set sk_forward_alloc. We just need to call sk_wmem_schedule() to check if the allocated should be raised, and call sk_mem_reclaim() to check if the allocated should be reduced when it's under memory pressure. If sk_wmem_schedule() returns false, which means no memory is allowed to allocate, it will block and wait for memory to become available. Note different from tcp, sctp wait_for_buf happens before allocating any skb, so memory accounting check is done with the whole msg_len before it too.

2019-03-20sctp: use memdup_user instead of vmemdup_userXin Long
In sctp_setsockopt_bindx()/__sctp_setsockopt_connectx(), it allocates memory with addrs_size which is passed from userspace. We used flag GFP_USER to put some more restrictions on it in Commit cacc06215271 ("sctp: use GFP_USER for user-controlled kmalloc"). However, since Commit c981f254cc82 ("sctp: use vmemdup_user() rather than badly open-coding memdup_user()"), vmemdup_user() has been used, which doesn't check GFP_USER flag when goes to vmalloc_*(). So when addrs_size is a huge value, it could exhaust memory and even trigger oom killer. This patch is to use memdup_user() instead, in which GFP_USER would work to limit the memory allocation with a huge addrs_size. Note we can't fix it by limiting 'addrs_size', as there's no demand for it from RFC.
