[PATCH v2] crypto: vmx - Fix sleep-in-atomic bugs

by Ondrej Mosnacek

This patch fixes sleep-in-atomic bugs in AES-CBC and AES-XTS VMX implementations. The problem is that the blkcipher_* functions should not be called in atomic context. The bugs can be reproduced via the AF_ALG interface by trying to encrypt/decrypt sufficiently large buffers (at least 64 KiB) using the VMX implementations of 'cbc(aes)' or 'xts(aes)'. Such operations then trigger BUG in crypto_yield(): [ 891.863680] BUG: sleeping function called from invalid context at include/crypto/algapi.h:424 [ 891.864622] in_atomic(): 1, irqs_disabled(): 0, pid: 12347, name: kcapi-enc [ 891.864739] 1 lock held by kcapi-enc/12347: [ 891.864811] #0: 00000000f5d42c46 (sk_lock-AF_ALG){+.+.}, at: skcipher_recvmsg+0x50/0x530 [ 891.865076] CPU: 5 PID: 12347 Comm: kcapi-enc Not tainted 4.19.0-0.rc0.git3.1.fc30.ppc64le #1 [ 891.865251] Call Trace: [ 891.865340] [c0000003387578c0] [c000000000d67ea4] dump_stack+0xe8/0x164 (unreliable) [ 891.865511] [c000000338757910] [c000000000172a58] ___might_sleep+0x2f8/0x310 [ 891.865679] [c000000338757990] [c0000000006bff74] blkcipher_walk_done+0x374/0x4a0 [ 891.865825] [c0000003387579e0] [d000000007e73e70] p8_aes_cbc_encrypt+0x1c8/0x260 [vmx_crypto] [ 891.865993] [c000000338757ad0] [c0000000006c0ee0] skcipher_encrypt_blkcipher+0x60/0x80 [ 891.866128] [c000000338757b10] [c0000000006ec504] skcipher_recvmsg+0x424/0x530 [ 891.866283] [c000000338757bd0] [c000000000b00654] sock_recvmsg+0x74/0xa0 [ 891.866403] [c000000338757c10] [c000000000b00f64] ___sys_recvmsg+0xf4/0x2f0 [ 891.866515] [c000000338757d90] [c000000000b02bb8] __sys_recvmsg+0x68/0xe0 [ 891.866631] [c000000338757e30] [c00000000000bbe4] system_call+0x5c/0x70 Fixes: 8c755ace357c ("crypto: vmx - Adding CBC routines for VMX module") Fixes: c07f5d3da643 ("crypto: vmx - Adding support for XTS") Cc: stable(a)vger.kernel.org Signed-off-by: Ondrej Mosnacek <omosnace(a)redhat.com> --- Still untested, please test and review if possible.

How to report kernel panic in 4.4.x

by Matthias B.

Hallo, 4.4.147 is the last kernel of the 4.4.x series that boots for me. All subsequent versions panic on boot. How do I report this bug? If I'm supposed to use https://bugzilla.kernel.org/ I don't know what to fill into the fields. I don't even know if the longterm kernel falls under "Mainline" or some other tree. MSB -- Fun chemistry experiments: Sodium chloride doubles its volume when combined with an equal amount of table salt.

kernel-doc patches for 4.18

by Nathan Chancellor

Hi Greg, Arch Linux recently enabled building the kernel documentation in their PKGBUILD, which turned my normally peaceful build into a spamfest of unescaped braces warnings from Perl. These are fixed upstream with the following two patches: 701b3a3c0ac4 ("PATCH scripts/kernel-doc") 673bb2dfc364 ("scripts/kernel-doc: Escape all literal braces in regexes") Could they please be applied to 4.18? They should be clean cherry-picks. Thanks! Nathan

Current LTS and their EOL

by Rodrigo Vivi

Hi Greg, Ben, and all Is https://www.kernel.org/category/releases.html updated in terms of EOL? Some news out of Linaro conference [2] generated a lot of doubts and questions around. Specially because on the way it was stated by the news 3.16 wouldn't be active anymore. So I'm not sure about the news, but I'd like confirmation from you about expected EOL. [2] https://itsfoss.com/linux-lts-kernel-six-years/ Thanks in advance, Rodrigo.

[PATCH v2] avoid race condition between start_xmit and cm_rep_handler

by Aaron Knister

Inside of start_xmit() the call to check if the connection is up and the queueing of the packets for later transmission is not atomic which leaves a window where cm_rep_handler can run, set the connection up, dequeue pending packets and leave the subsequently queued packets by start_xmit() sitting on neigh->queue until they're dropped when the connection is torn down. This only applies to connected mode. These dropped packets can really upset TCP, for example, and cause multi-minute delays in transmission for open connections. Here's the code in start_xmit where we check to see if the connection is up: if (ipoib_cm_get(neigh)) { if (ipoib_cm_up(neigh)) { ipoib_cm_send(dev, skb, ipoib_cm_get(neigh)); goto unref; } } The race occurs if cm_rep_handler execution occurs after the above connection check (specifically if it gets to the point where it acquires priv->lock to dequeue pending skb's) but before the below code snippet in start_xmit where packets are queued. if (skb_queue_len(&neigh->queue) < IPOIB_MAX_PATH_REC_QUEUE) { push_pseudo_header(skb, phdr->hwaddr); spin_lock_irqsave(&priv->lock, flags); __skb_queue_tail(&neigh->queue, skb); spin_unlock_irqrestore(&priv->lock, flags); } else { ++dev->stats.tx_dropped; dev_kfree_skb_any(skb); } The patch re-checks ipoib_cm_up with priv->lock held to avoid this race condition. Since odds are the conn should be up most of the time (and thus the connection *not* down most of the time) we don't hold the lock for the first check attempt to avoid a slowdown from unecessary locking for the majority of the packets transmitted during the connection's life.
