Public bug reported:
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree or
a minimally backported form of that patch. The 4.4.34 upstream stable
patch set is now available. It should be included in the Ubuntu
kernel as well.
git://git.kernel.org/
TEST CASE: TBD
The following patches from the 4.4.34 stable release shall be
applied:
dctcp: avoid bogus doubling of cwnd after loss
net: clear sk_err_soft in sk_clone_lock()
net: mangle zero checksum in skb_checksum_help()
bgmac: stop clearing DMA receive control register right after it is set
ip6_tunnel: Clear IP6CB in ip6tunnel_xmit()
tcp: fix potential memory corruption
dccp: do not send reset to already closed sockets
dccp: fix out of bound access in dccp_v4_err()
ipv6: dccp: fix out of bound access in dccp_v6_err()
ipv6: dccp: add missing bind_conflict to dccp_ipv6_mapped
sctp: assign assoc_id earlier in __sctp_connect
fib_trie: Correct /proc/net/route off by one error
sock: fix sendmmsg for partial sendmsg
net: __skb_flow_dissect() must cap its return value
ipv4: use new_gw for redirect neigh lookup
tcp: take care of truncations done by sk_filter()
tty: Prevent ldisc drivers from re-using stale tty fields
sparc: Don't leak context bits into thread->fault_address
sparc: serial: sunhv: fix a double lock bug
sparc64 mm: Fix base TSB sizing when hugetlb pages are used
sparc: Handle negative offsets in arch_jump_label_transform
sparc64: Handle extremely large kernel TSB range flushes sanely.
sparc64: Fix illegal relative branches in hypervisor patched TLB code.
sparc64: Fix instruction count in comment for __hypervisor_flush_tlb_pending.
sparc64: Fix illegal relative branches in hypervisor patched TLB cross-call
code.

sparc64: Prepare to move to more saner user copy exception handling.
sparc64: Convert copy_in_user to accurate exception reporting.
sparc64: Convert GENcopy_{from,to}_user to accurate exception reporting.
sparc64: Convert U1copy_{from,to}_user to accurate exception reporting.
sparc64: Convert NG4copy_{from,to}_user to accurate exception reporting.
sparc64: Convert NGcopy_{from,to}_user to accurate exception reporting.
sparc64: Convert NG2copy_{from,to}_user to accurate exception reporting.
sparc64: Convert U3copy_{from,to}_user to accurate exception reporting.
sparc64: Delete now unused user copy assembler helpers.
