When processing a duplicate cookie-echo chunk, sctp moves the new temp asoc's stream out/in into the old asoc, and later frees this new temp asoc. But now after this move, the new temp asoc's stream->outcnt is not cleared while stream->out is set to NULL, which would cause a same crash as the one fixed in Commit 79d08951 ("sctp: fix error path in sctp_stream_init") when freeing this asoc later. This fix is to clear this outcnt in sctp_stream_update.

Since sctp ipv6 socket also supports v4 addrs, it's possible to compare two v4 addrs in pf v6 .cmp_addr, sctp_inet6_cmp_addr. However after Commit 1071ec9d ("sctp: do not check port in sctp_inet6_cmp_addr"), it no longer calls af1->cmp_addr, which in this case is sctp_v4_cmp_addr, but calls __sctp_v6_cmp_addr where it handles them as two v6 addrs. It would cause a out of bounds crash. syzbot found this crash when trying to bind two v4 addrs to a v6 socket. This patch fixes it by adding the process for two v4 addrs in sctp_inet6_cmp_addr.

While adding the DSA notifier, we will be sending DSA notifications with info->master that is going to point to a particular net_device instance. Our logic in bcm_sysport_map_queues() correctly disambiguates net_device instances that are not covered by our own driver, but it will not make sure that info->master points to a particular driver instance that we are interested in. In a system where e.g: two or more SYSTEMPORT instances are registered, this would lead in programming two or more times the queue mapping, completely messing with the logic which does the queue/port allocation and tracking. Fix this by looking at the notifier_block pointer which is unique per instance and allows us to go back to our driver private structure, and in turn to the backing net_device instance.

The TCP repair sequence of operation is to first set the socket in repair mode, then inject the TCP stats into the socket with repair socket options, then call connect() to re-activate the socket. The connect syscall simply returns and set state to ESTABLISHED mode. As a result Fast Open is meaningless for TCP repair. However allowing sendto() system call with MSG_FASTOPEN flag half-way during the repair operation could unexpectedly cause data to be sent, before the operation finishes changing the internal TCP stats (e.g. MSS). This in turn triggers TCP warnings on inconsistent packet accounting. The fix is to simply disallow Fast Open operation once the socket is in the repair mode.

The internal CLC socket should exist till the SMC-socket is released. Function tcp_listen_worker() releases the internal CLC socket of a listen socket, if an smc_close_active() is called. This function is called for the final release(), but it is called for shutdown SHUT_RDWR as well. This opens a door for protection faults, if socket calls using the internal CLC socket are called for a shutdown listen socket. With the changes of commit 3d502067 ("net/smc: simplify wait when closing listen socket") there is no need anymore to release the internal CLC socket in function tcp_listen_worker(().

由 Gianluca Borello 提交于
Commit 2a5418a1 ("bpf: improve dead code sanitizing") replaced dead code with a series of ja-1 instructions, for safety. That made JIT compilation much more complex for some BPF programs. One instance of such programs is, for example: bool flag = false ... /* A bunch of other code */ ... if (flag) do_something() In some cases llvm is not able to remove at compile time the code for do_something(), so the generated BPF program ends up with a large amount of dead instructions. In one specific real life example, there are two series of ~500 and ~1000 dead instructions in the program. When the verifier replaces them with a series of ja-1 instructions, it causes an interesting behavior at JIT time. During the first pass, since all the instructions are estimated at 64 bytes, the ja-1 instructions end up being translated as 5 bytes JMP instructions (0xE9), since the jump offsets become increasingly large (> 127) as each instruction gets discovered to be 5 bytes instead of the estimated 64. Starting from the second pass, the first N instructions of the ja-1 sequence get translated into 2 bytes JMPs (0xEB) because the jump offsets become <= 127 this time. In particular, N is defined as roughly 127 / (5 - 2) ~= 42. So, each further pass will make the subsequent N JMP instructions shrink from 5 to 2 bytes, making the image shrink every time. This means that in order to have the entire program converge, there need to be, in the real example above, at least ~1000 / 42 ~= 24 passes just for translating the dead code. If we add this number to the passes needed to translate the other non dead code, it brings such program to 40+ passes, and JIT doesn't complete. Ultimately the userspace loader fails because such BPF program was supposed to be part of a prog array owner being JITed. While it is certainly possible to try to refactor such programs to help the compiler remove dead code, the behavior is not really intuitive and it puts further burden on the BPF developer who is not expecting such behavior. To make things worse, such programs are working just fine in all the kernel releases prior to the ja-1 fix. A possible approach to mitigate this behavior consists into noticing that for ja-1 instructions we don't really need to rely on the estimated size of the previous and current instructions, we know that a -1 BPF jump offset can be safely translated into a 0xEB instruction with a jump offset of -2. Such fix brings the BPF program in the previous example to complete again in ~9 passes.

Update xgbe-phy-v2.c to make use of the auto-negotiation (AN) phy hooks to improve the ability to successfully complete Clause 73 AN when running at 10gbps. Hardware can sometimes have issues with CDR lock when the AN DME page exchange is being performed. The AN and KR training hooks are used as follows: - The pre AN hook is used to disable CDR tracking in the PHY so that the DME page exchange can be successfully and consistently completed. - The post KR training hook is used to re-enable the CDR tracking so that KR training can successfully complete. - The post AN hook is used to check for an unsuccessful AN which will increase a CDR tracking enablement delay (up to a maximum value). Add two debugfs entries to allow control over use of the CDR tracking workaround. The debugfs entries allow the CDR tracking workaround to be disabled and determine whether to re-enable CDR tracking before or after link training has been initiated. Also, with these changes the receiver reset cycle that is performed during the link status check can be performed less often.

We must validate sockaddr_len, otherwise userspace can pass fewer data than we expect and we end up accessing invalid data.

If WOL event happened once, the LED[2] interrupt pin will not be cleared unless we read the CSISR register. If interrupts are in use, the normal interrupt handling will clear the WOL event. Let's clear the WOL event before enabling it if !phy_interrupt_is_valid().

John Fastabend says: ==================== While testing sockmap with more programs (besides our test programs) I found a couple issues. The attached series fixes an issue where pinned maps were not working correctly, blocking sockets returned zero, and an error path that when the sock hit an out of memory case resulted in a double page_put() while doing ingress redirects. See individual patches for more details. v2: Incorporated Daniel's feedback to use map ops for uref put op which also fixed the build error discovered in v1. v3: rename map_put_uref to map_release_uref ==================== Signed-off-by: NDaniel Borkmann <daniel@iogearbox.net>

In the case where the socket memory boundary is hit the redirect path returns an ENOMEM error. However, before checking for this condition the redirect scatterlist buffer is setup with a valid page and length. This is never unwound so when the buffers are released latter in the error path we do a put_page() and clear the scatterlist fields. But, because the initial error happens before completing the scatterlist buffer we end up with both the original buffer and the redirect buffer pointing to the same page resulting in duplicate put_page() calls. To fix this simply move the initial configuration of the redirect scatterlist buffer below the sock memory check. Found this while running TCP_STREAM test with netperf using Cilium.
