PCI: of: Warn if non-prefetchable memory aperture size is > 32-bit
As per PCIe spec r5.0, sec 7.5.1.3.8 only 32-bit BAR registers are defined for non-prefetchable memory and hence a warning should be reported when the size of them go beyond 32-bits.

PCI: dwc: Support multiple ATU memory regions
The current ATU setup only supports a single memory resource which isn't sufficient if there are also prefetchable memory regions. In order to support multiple memory regions, we need to move away from fixed ATU slots and rework the assignment. As there's always an ATU entry for config space, let's assign index 0 to config space. Then we assign memory resources to index 1 and up. Finally, if we have an I/O region and slots remaining, we assign the I/O region last. If there aren't remaining slots, we keep the same config and I/O space sharing.

TTY/Serial fixes for 5.10-rc3
Here are a small number of small tty and serial fixes for some reported
problems for the tty core, vt code, and some serial drivers.
They include fixes for:
- a buggy and obsolete vt font ioctl removal
- 8250_mtk serial baudrate runtime warnings
- imx serial earlycon build configuration fix
- txx9 serial driver error path cleanup issues
- tty core fix in release_tty that can be triggered by trying to
bind an invalid serial port name to a speakup console device
Almost all of these have been in linux-next without any problems, the
only one that hasn't, just deletes code :)

vt: Disable KD_FONT_OP_COPY
It's buggy: On Fri, Nov 06, 2020 at 10:30:08PM +0800, Minh Yuan wrote: > We recently discovered a slab-out-of-bounds read in fbcon in the latest > kernel ( v5.10-rc2 for now ).

Obviously, this will cause an out-of-bounds read, because we can > access a smaller vc_font.data with a larger vc_font.height. Further there was only one user ever. - Android's loadfont, busybox and console-tools only ever use OP_GET and OP_SET - fbset documentation only mentions the kernel cmdline font: option, not anything else. - systemd used OP_COPY before release 232 published in Nov 2016 Now unfortunately the crucial report seems to have gone down with gmane, and the commit message doesn't say much. But the pull request hints at OP_COPY being broken https://github.com/systemd/systemd/pull/3651 So in other words, this never worked, and the only project which foolishly every tried to use it, realized that rather quickly too. Instead of trying to fix security issues here on dead code by adding missing checks, fix the entire thing by removing the functionality. Note that systemd code using the OP_COPY function ignored the return value, so it doesn't matter what we're doing here really - just in case a lone server somewhere happens to be extremely unlucky and running an affected old version of systemd. The relevant code from font_copy_to_all_vcs() in systemd was: /* copy font from active VT, where the font was uploaded to */ cfo.op = KD_FONT_OP_COPY; cfo.height = vcs.v_active-1; /* tty1 == index 0 */ (void) ioctl(vcfd, KDFONTOP, &cfo); Note this just disables the ioctl, garbage collecting the now unused callbacks is left for -next. v2: Tetsuo found the old mail, which allowed me to find it on another archive.

Merge branch 'hch' (patches from Christoph)
Merge procfs splice read fixes from Christoph Hellwig:
"Greg reported a problem due to the fact that Android tests use procfs
files to test splice, which stopped working with the changes for
set_fs() removal.
This series adds read_iter support for seq_file, and uses those for
various proc files using seq_file to restore splice read support"
[ Side note: Christoph initially had a scripted "move everything over"
patch, which looks fine, but I personally would prefer us to actively
discourage splice() on random files. So this does just the minimal
basic core set of proc file op conversions.
For completeness, and in case people care, that script was
sed -i -e 's/\.proc_read\(\s*=\s*\)seq_read/\.proc_read_iter\1seq_read_iter/g'
but I'll wait and see if somebody has a strong argument for using
splice on random small /proc files before I'd run it on the whole
kernel. - Linus ]
* emailed patches from Christoph Hellwig <hch@lst.de>:
proc "seq files": switch to ->read_iter
proc "single files": switch to ->read_iter
proc/stat: switch to ->read_iter
proc/cpuinfo: switch to ->read_iter

futex: Handle transient "ownerless" rtmutex state correctly
Gratian managed to trigger the BUG_ON(!newowner) in fixup_pi_state_owner().
This is one possible chain of events leading to this:
Task Prio Operation
T1 120 lock(F)
T2 120 lock(F) -> blocks (top waiter)
T3 50 (RT) lock(F) -> boosts T1 and blocks (new top waiter)
XX timeout/ -> wakes T2
signal
T1 50 unlock(F) -> wakes T3 (rtmutex->owner == NULL, waiter bit is set)
T2 120 cleanup -> try_to_take_mutex() fails because T3 is the top waiter
and the lower priority T2 cannot steal the lock.
-> fixup_pi_state_owner() sees newowner == NULL -> BUG_ON()
The comment states that this is invalid and rt_mutex_real_owner() must
return a non NULL owner when the trylock failed, but in case of a queued
and woken up waiter rt_mutex_real_owner() == NULL is a valid transient
state. The higher priority waiter has simply not yet managed to take over
the rtmutex.
The BUG_ON() is therefore wrong and this is just another retry condition in
fixup_pi_state_owner().
Drop the locks, so that T3 can make progress, and then try the fixup again.
Gratian provided a great analysis, traces and a reproducer. The analysis is
to the point, but it confused the hell out of that tglx dude who had to
page in all the futex horrors again. Condensed version is above.

perf/core: Fix a memory leak in perf_event_parse_addr_filter()
As shown through runtime testing, the "filename" allocation is not
always freed in perf_event_parse_addr_filter().
There are three possible ways that this could happen:
- It could be allocated twice on subsequent iterations through the loop,
- or leaked on the success path,
- or on the failure path.
Clean up the code flow to make it obvious that 'filename' is always
freed in the reallocation path and in the two return paths as well.
We rely on the fact that kfree(NULL) is NOP and filename is initialized
with NULL.
This fixes the leak. No other side effects expected.
[ Dan Carpenter: cleaned up the code flow & added a changelog. ]
[ Ingo Molnar: updated the changelog some more. ]

Networking fixes for 5.10-rc3, including fixes from wireless, can,
and netfilter subtrees.
Current release - bugs in new features:
- can: isotp: isotp_rcv_cf(): enable RX timeout handling in
listen-only mode
Previous release - regressions:
- mac80211:
- don't require VHT elements for HE on 2.4 GHz
- fix regression where EAPOL frames were sent in plaintext
- netfilter:
- ipset: Update byte and packet counters regardless of whether
they match
- ip_tunnel: fix over-mtu packet send by allowing fragmenting even
if inner packet has IP_DF (don't fragment) set in its header
(when TUNNEL_DONT_FRAGMENT flag is not set on the tunnel dev)
- net: fec: fix MDIO probing for some FEC hardware blocks
- ip6_tunnel: set inner ipproto before ip6_tnl_encap to un-break
gso support
- sctp: Fix COMM_LOST/CANT_STR_ASSOC err reporting on big-endian
platforms, sparse-related fix used the wrong integer size
Previous release - always broken:
- netfilter: use actual socket sk rather than skb sk when routing
harder
- r8169: work around short packet hw bug on RTL8125 by padding frames
- net: ethernet: ti: cpsw: disable PTPv1 hw timestamping
advertisement, the hardware does not support it
- chelsio/chtls: fix always leaking ctrl_skb and another leak caused
by a race condition
- fix drivers incorrectly writing into skbs on TX:
- cadence: force nonlinear buffers to be cloned
- gianfar: Account for Tx PTP timestamp in the skb headroom
- gianfar: Replace skb_realloc_headroom with skb_cow_head for PTP
- can: flexcan:
- remove FLEXCAN_QUIRK_DISABLE_MECR quirk for LS1021A
- add ECC initialization for VF610 and LX2160A
- flexcan_remove(): disable wakeup completely
- can: fix packet echo functionality:
- peak_canfd: fix echo management when loopback is on
- make sure skbs are not freed in IRQ context in case they need
to be dropped
- always clone the skbs to make sure they have a reference on
the socket, and prevent it from disappearing
- fix real payload length return value for RTR frames
- can: j1939: return failure on bind if netdev is down, rather than
waiting indefinitely
Misc:
- IPv6: reply ICMP error if the first fragment don't include all
headers to improve compliance with RFC 8200

Add the missing platform_driver_unregister() before return
from serial_txx9_init in the error handling case when failed
to register serial_txx9_pci_driver with macro ENABLE_SERIAL_TXX9_PCI
defined.
