[Linux-stable-mirror] commit df80cd9b28b9 added twice to 4.4-stable

by Michal Kubecek

Hello, I noticed that mainline commit df80cd9b28b9 ("sctp: do not peel off an assoc from one netns to another one") has been backported to stable 4.4 branch twice: - first as commit 46bdabbca02e in 4.4.100 - then again as commit 2a0e60907e54 in 4.4.101 so that the check it adds in sctp_do_peeloff() is now performed twice.

[Linux-stable-mirror] [PATCH] X.509: fix comparisons of ->pkey_algo

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> ->pkey_algo used to be an enum, but was changed to a string by commit 4e8ae72a75aa ("X.509: Make algo identifiers text instead of enum"). But two comparisons were not updated. Fix them to use strcmp(). This bug broke signature verification in certain configurations, depending on whether the string constants were deduplicated or not.

[Linux-stable-mirror] [PATCH] Revert "async: simplify lowest_in_progress()"

by Rasmus Villemoes

This reverts commit 92266d6ef60c2381c980c6cdcb2a5c1667b36b49, which was simply wrong: In the case where domain is NULL, we now use the wrong offsetof() in the list_first_entry macro, so we don't actually fetch the ->cookie value, but rather the eight bytes located sizeof(struct list_head) further into the struct async_entry. On 64 bit, that's the data member, while on 32 bit, we get a u64 built from func and data in some order. I think the bug happens to be harmless in practice: It obviously only affects callers which pass a NULL domain, and AFAICT the only such caller is async_synchronize_full() -> async_synchronize_full_domain(NULL) -> async_synchronize_cookie_domain(ASYNC_COOKIE_MAX, NULL) and the ASYNC_COOKIE_MAX means that in practice we end up waiting for the async_global_pending list to be empty - but it would break if somebody happened to pass (void*)-1 as the data element to async_schedule, and of course also if somebody ever does a async_synchronize_cookie_domain(, NULL) with a "finite" cookie value. Cc: stable(a)vger.kernel.org # 3.10+ Signed-off-by: Rasmus Villemoes <linux(a)rasmusvillemoes.dk> --- Maybe the "harmless in practice" means this isn't -stable material. But I'm not completely confident my quick git grep'ing is enough, and there might be affected code in one of the earlier kernels that has since been removed, so I'll leave the decision to the stable guys. kernel/async.c | 20 ++++++++++++-------- 1 file changed, 12 insertions(+), 8 deletions(-) diff --git a/kernel/async.c b/kernel/async.c index 2cbd3dd5940d..a893d6170944 100644 --- a/kernel/async.c +++ b/kernel/async.c @@ -84,20 +84,24 @@ static atomic_t entry_count; static async_cookie_t lowest_in_progress(struct async_domain *domain) { - struct list_head *pending; + struct async_entry *first = NULL; async_cookie_t ret = ASYNC_COOKIE_MAX; unsigned long flags; spin_lock_irqsave(&async_lock, flags); - if (domain) - pending = &domain->pending; - else - pending = &async_global_pending; + if (domain) { + if (!list_empty(&domain->pending)) + first = list_first_entry(&domain->pending, + struct async_entry, domain_list); + } else { + if (!list_empty(&async_global_pending)) + first = list_first_entry(&async_global_pending, + struct async_entry, global_list); + } - if (!list_empty(pending)) - ret = list_first_entry(pending, struct async_entry, - domain_list)->cookie; + if (first) + ret = first->cookie; spin_unlock_irqrestore(&async_lock, flags); return ret; -- 2.11.0

[Linux-stable-mirror] Patch "e1000e: fix buffer overrun while the I219 is processing DMA transactions" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled e1000e: fix buffer overrun while the I219 is processing DMA transactions to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: e1000e-fix-buffer-overrun-while-the-i219-is-processing-dma-transactions.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From b10effb92e272051dd1ec0d7be56bf9ca85ab927 Mon Sep 17 00:00:00 2001 From: Sasha Neftin <sasha.neftin(a)intel.com> Date: Sun, 6 Aug 2017 16:49:18 +0300 Subject: e1000e: fix buffer overrun while the I219 is processing DMA transactions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit From: Sasha Neftin <sasha.neftin(a)intel.com> commit b10effb92e272051dd1ec0d7be56bf9ca85ab927 upstream. Intel® 100/200 Series Chipset platforms reduced the round-trip latency for the LAN Controller DMA accesses, causing in some high performance cases a buffer overrun while the I219 LAN Connected Device is processing the DMA transactions. I219LM and I219V devices can fall into unrecovered Tx hang under very stressfully UDP traffic and multiple reconnection of Ethernet cable. This Tx hang of the LAN Controller is only recovered if the system is rebooted. Slightly slow down DMA access by reducing the number of outstanding requests. This workaround could have an impact on TCP traffic performance on the platform. Disabling TSO eliminates performance loss for TCP traffic without a noticeable impact on CPU performance.

[Linux-stable-mirror] Patch "xen: xenbus driver must not accept invalid transaction ids" has been added to the 3.18-stable tree

Xenstore is validating a transaction id against all known transaction ids of the connection the request came in. As all requests of a domain not being the one where Xenstore lives share one connection, validation of transaction ids of different users of Xenstore in that domain should be done by the kernel of that domain being the multiplexer between the Xenstore users in that domain and Xenstore. In order to prohibit one Xenstore user "hijacking" a transaction from another user the xenbus driver has to verify a given transaction id against all known transaction ids of the user before forwarding it to Xenstore.
