[GIT PULL] Networking for 5.11-rc4

[GIT PULL] Networking for 5.11-rc4

[Jakub Kicinski]

Hi!

We have a few fixes for long standing issues, in particular
Eric's fix to not underestimate the skb sizes, and my fix for
brokenness of register_netdevice() error path. They may uncover
other bugs so we will keep an eye on them. Also included are
Willem's fixes for kmap(_atomic).

Looking at the "current release" fixes, it seems we are about
one rc behind a normal cycle. We've previously seen an uptick
of "people had run their test suites" / "humans actually tried 
to use new features" fixes between rc2 and rc3.

The following changes since commit 6279d812eab67a6df6b22fa495201db6f2305924:

  Merge tag 'net-5.11-rc3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net (2021-01-08 12:12:30 -0800)

  mptcp: fix locking in mptcp_disconnect() (2021-01-14 11:25:21 -0800)

----------------------------------------------------------------
Networking fixes for 5.11-rc4, including fixes from can and netfilter.

Current release - regressions:

 - fix feature enforcement to allow NETIF_F_HW_TLS_TX
   if IP_CSUM && IPV6_CSUM

 - dcb: accept RTM_GETDCB messages carrying set-like DCB commands
        if user is admin for backward-compatibility

 - selftests/tls: fix selftests build after adding ChaCha20-Poly1305

Current release - always broken:

 - ppp: fix refcount underflow on channel unbridge

 - bnxt_en: clear DEFRAG flag in firmware message when retry flashing

 - smc: fix out of bound access in the new netlink interface

Previous releases - regressions:

 - fix use-after-free with UDP GRO by frags

 - mptcp: better msk-level shutdown

 - rndis_host: set proper input size for OID_GEN_PHYSICAL_MEDIUM request

 - i40e: xsk: fix potential NULL pointer dereferencing

Previous releases - always broken:

 - skb frag: kmap_atomic fixes

 - avoid 32 x truesize under-estimation for tiny skbs

 - fix issues around register_netdevice() failures

 - udp: prevent reuseport_select_sock from reading uninitialized socks

 - dsa: unbind all switches from tree when DSA master unbinds

 - dsa: clear devlink port type before unregistering slave netdevs

 - can: isotp: isotp_getname(): fix kernel information leak

 - mlxsw: core: Thermal control fixes

 - ipv6: validate GSO SKB against MTU before finish IPv6 processing

 - stmmac: use __napi_schedule() for PREEMPT_RT

 - net: mvpp2: remove Pause and Asym_Pause support

Misc:

 - remove from MAINTAINERS folks who had been inactive for >5yrs

So I understand what you mean, but it does sound odd with that
"Current release - always broken" thing not being a regression. The
"always broken" makes it sound like it's some old broken code that has
never worked, which it clearly isn't.

Maybe rephrase it as "new code bugs" or something? You've done that
before ("bugs in new features").

I left it alone in the merge message, since we've had that pattern of
speech before, but for some reason I reacted to it this time.

Will do, I succumbed to the lure of matching "Previous releases -
always broken".
