Hm, sorry, I take this last part back. I cannot reproduce -G not working
reliably.
I'll dig around the conntrack table a bit more.

I have a basic firewall setup with default rules e.g. starts with

That said, I just dropped it on the server to check a

The usage of of_device_get_match_data() reduce the code size a bit.
Also, the only way to call mtk_probe() is to match an entry in
of_mtk_match[], so match cannot be NULL.

Hi all,
After merging the bpf tree, today's linux-next build (arm

It would allocate memory in this function when the cork->opt is NULL. But
the memory isn't freed if failed in the latter rt check, and return error
directly. It causes the memleak if its caller is ip_make_skb which also
doesn't free the cork->opt when meet a error.

While a faulty cable is used or HCA firmware error, HCA device will

In order to remove the race caught by syzbot [1], we need
to lock the socket before using po->tp_version as this could
change under us otherwise.
This means lock_sock() and release_sock() must be done by
packet_set_ring() callers.

Due to a firmware bug, the hypervisor can send an interrupt to a
transmit or receive queue just prior to a partition migration, not
allowing the device enough time to handle it and send an EOI. When
the partition migrates, the interrupt is lost but an "EOI-pending"
flag for the interrupt line is st

Hi,
I can confirm that this patch solves the issue for us and restores
previous behavior.
Thank you.

Hi all,
While I read __tcp_select_window() code, I find that it maybe return a
smaller window.
Below is one scenario I thought, may be not right:
In function __tcp_select_window(), assume:
full_space is 6mss, free_space is 2mss, tp->rcv_wnd is 3MSS.
And assume disable window scaling, then
window =
