I'm announcing the release of the 5.2.7 kernel. All users of the 5.2 kernel series must upgrade. The updated 5.2.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.2.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Documentation/admin-guide/hw-vuln/spectre.rst | 88 ++++++++++++++++- Documentation/admin-guide/kernel-parameters.txt | 8 -

When seeking to a record boundary, the next record is correctly returned. This bug was introduced by a recent patch (identified below). Before that patch, seq_read() would increment m->index when the last of the buffer was returned (m->count == 0). After that patch, we rely on ->next to increment m->index after filling the buffer - but there was one place where that didn't happen.

The patch titled Subject: memcg, oom: don't require __GFP_FS when invoking memcg OOM killer has been added to the -mm tree.

It turned out that try_charge() is retrying forever without making forward progress because mem_cgroup_oom(GFP_NOFS) cannot invoke the OOM killer due to commit 3da88fb3bacfaa33 ("mm, oom: move GFP_NOFS check to out_of_memory"). Allowing forced charge due to being unable to invoke memcg OOM killer will lead to global OOM situation. Also, just returning -ENOMEM will be risky because OOM path is lost and some paths (e.g. get_user_pages()) will leak -ENOMEM. Therefore, invoking memcg OOM killer (despite GFP_NOFS) will be the only choice we can choose for now. Until 29ef680ae7c21110, we were able to invoke memcg OOM killer when GFP_KERNEL reclaim failed [1]. But since 29ef680ae7c21110, we need to invoke memcg OOM killer when GFP_NOFS reclaim failed [2]. Although in the past we did invoke memcg OOM killer for GFP_NOFS [3], we might get pre-mature memcg OOM reports due to this patch.

[5.2-stable PATCH 1/2] libnvdimm/bus: Prepare the nd_ioctl() path to be re-entrant

by Dan Williams

commit 6de5d06e657acdbcf9637dac37916a4a5309e0f4 upstream. In preparation for not holding a lock over the execution of nd_ioctl(), update the implementation to allow multiple threads to be attempting ioctls at the same time. The bus lock still prevents multiple in-flight ->ndctl() invocations from corrupting each other's state, but static global staging buffers are moved to the heap.

Recent patches to address CVE-2019-11478 broke them in case of losses, since retransmits might be prevented. We should allow these flows to make progress. This patch allows the first and last skb in retransmit queue to be split even if memory limits are hit. It also adds the some room due to the fact that tcp_sendmsg() and tcp_sendpage() might overshoot sk_wmem_queued by about one full TSO skb (64KB size). Note this allowance was already present in stable backports for kernels < 4.15 Note for < 4.15 backports : tcp_rtx_queue_tail() will probably look like : static inline struct sk_buff *tcp_rtx_queue_tail(const struct sock *sk) { struct sk_buff *skb = tcp_send_head(sk); return skb ? tcp_write_queue_prev(sk, skb) : tcp_write_queue_tail(sk); } Fixes: f070ef2ac667 ("tcp: tcp_fragment() should apply sane memory limits") Signed-off-by: Eric Dumazet <edumazet(a)google.com> Reported-by: Andrew Prout <aprout(a)ll.mit.edu> Tested-by: Andrew Prout <aprout(a)ll.mit.edu> Tested-by: Jonathan Lemon <jonathan.lemon(a)gmail.com> Tested-by: Michal Kubecek <mkubecek(a)suse.cz> Acked-by: Neal Cardwell <ncardwell(a)google.com> Acked-by: Yuchung Cheng <ycheng(a)google.com> Acked-by: Christoph Paasch <cpaasch(a)apple.com> Cc: Jonathan Looney <jtl(a)netflix.com> Signed-off-by: David S.

[PATCH] driver core: platform: return -ENXIO for missing GpioInt

by Brian Norris

Commit daaef255dc96 ("driver: platform: Support parsing GpioInt 0 in platform_get_irq()") broke the Embedded Controller driver on most LPC Chromebooks (i.e., most x86 Chromebooks), because cros_ec_lpc expects platform_get_irq() to return -ENXIO for non-existent IRQs. Unfortunately, acpi_dev_gpio_irq_get() doesn't follow this convention and returns -ENOENT instead. So we get this error from cros_ec_lpc: couldn't retrieve IRQ number (-2) I see a variety of drivers that treat -ENXIO specially, so rather than fix all of them, let's fix up the API to restore its previous behavior. I reported this on v2 of this patch: https://lore.kernel.org/lkml/20190220180538.GA42642@google.com/ but apparently the patch had already been merged before v3 got sent out: https://lore.kernel.org/lkml/20190221193429.161300-1-egranata@chromium.org/ and the result is that the bug landed and remains unfixed. I differ from the v3 patch by: * allowing for ret==0, even though acpi_dev_gpio_irq_get() specifically documents (and enforces) that 0 is not a valid return value (noted on the v3 review) * adding a small comment Reported-by: Brian Norris <briannorris(a)chromium.org> Reported-by: Salvatore Bellizzi <salvatore.bellizzi(a)linux.seppia.net> Cc: Enrico Granata <egranata(a)chromium.org> Cc: <stable(a)vger.kernel.org> Fixes: daaef255dc96 ("driver: platform: Support parsing GpioInt 0 in platform_get_irq()") Signed-off-by: Brian Norris <briannorris(a)chromium.org> --- Side note: it might have helped alleviate some of this pain if there were email notifications to the mailing list when a patch gets applied. I didn't realize (and I'm not sure if Enrico did) that v2 was already merged by the time I noted its mistakes. If I had known, I would have suggested a follow-up patch, not a v3.
