Subject: [PATCH] ipv6: Don't reduce hop limit for an interface
|
||||
|
||||
A local route may have a lower hop_limit set than global routes do.
|
||||
|
||||
RFC 3756, Section 4.2.7, "Parameter Spoofing"
|
||||
|
||||
> 1. The attacker includes a Current Hop Limit of one or another small
|
||||
> number which the attacker knows will cause legitimate packets to
|
||||
> be dropped before they reach their destination.
|
||||
|
||||
> As an example, one possible approach to mitigate this threat is to
|
||||
> ignore very small hop limits. The nodes could implement a
|
||||
> configurable minimum hop limit, and ignore attempts to set it below
|
||||
> said limit.

Subject: [PATCH] tg3: Hold tp->lock before calling tg3_halt() from
|
||||
tg3_init_one()
|
||||
|
||||
tg3_init_one() calls tg3_halt() without tp->lock despite its assumption
|
||||
and causes deadlock.
|
||||
If lockdep is enabled, a warning like this shows up before the stall:
|
||||
|
||||
[ BUG: bad unlock balance detected! ]
|
||||
3.19.0test #3 Tainted: G E
|
||||
-------------------------------------
|
||||
insmod/369 is trying to release lock (&(&tp->lock)->rlock) at:
|
||||
[<ffffffffa02d5a1d>] tg3_chip_reset+0x14d/0x780 [tg3]
|
||||
but there are no more locks to release!
|
||||
|
||||
tg3_init_one() doesn't call tg3_halt() under normal situation but
|
||||
during kexec kdump I hit this problem.
|
||||
|
||||

Subject: [PATCH] tun: return proper error code from tun_do_read
|
||||
|
||||
Instead of -1 with EAGAIN, read on a O_NONBLOCK tun fd will return 0. This
|
||||
fixes this by properly returning the error code from __skb_recv_datagram.
