They were cleanups, but they break dosemu by changing the signal return behavior (and removing 'fs' and 'gs' from the sigcontext struct - while not actually changing any behavior - causes build problems).

Jakub Kicinski authored
Current filer rule optimization is broken in several ways: (1) Can perform reads/writes beyond end of allocated tables. (gianfar_ethtool.c:1326). (2) It breaks badly for rules with more than 2 specifiers (e.g. matching ip, port, tos). Example: # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.1 dst-port 1 tos 1 action 1 Added rule with ID 254 # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.2 dst-port 2 tos 2 action 9 Added rule with ID 253 # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.3 dst-port 3 tos 3 action 17 Added rule with ID 252 # ./filer_decode /sys/kernel/debug/gfar1/filer_raw 00: MASK == 00000210 AND Q:00 ctrl:00000080 prop:00000210 01: FPR == 00000210 AND CLE Q:00 ctrl:00000281 prop:00000210 02: MASK == ffffffff AND Q:00 ctrl:00000080 prop:ffffffff 03: DPT == 00000003 AND Q:00 ctrl:0000008e prop:00000003 04: TOS == 00000003 AND Q:00 ctrl:0000008a prop:00000003 05: DIA == 0a000003 AND Q:11 ctrl:0000448c prop:0a000003 06: DPT == 00000002 AND Q:00 ctrl:0000008e prop:00000002 07: TOS == 00000002 AND Q:00 ctrl:0000008a prop:00000002 08: DIA == 0a000002 AND Q:09 ctrl:0000248c prop:0a000002 09: DIA == 0a000001 AND Q:00 ctrl:0000008c prop:0a000001 0a: DPT == 00000001 AND Q:00 ctrl:0000008e prop:00000001 0b: TOS == 00000001 CLE Q:01 ctrl:0000060a prop:00000001 ff: MASK >= 00000000 Q:00 ctrl:00000020 prop:00000000 (Entire cluster gets AND-ed together). (3) We observed that the masking rules it generates do not play well with clustering on P2020. Only first rule of the cluster would ever fire. Given that optimizer relies heavily on masking this is very hard to fix. Example: # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.1 dst-port 1 action 1 Added rule with ID 254 # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.2 dst-port 2 action 9 Added rule with ID 253 # ethtool -N eth2 flow-type udp4 dst-ip 10.0.0.3 dst-port 3 action 17 Added rule with ID 252 # ./filer_decode /sys/kernel/debug/gfar1/filer_raw 00: MASK == 00000210 AND Q:00 ctrl:00000080 prop:00000210 01: FPR == 00000210 AND CLE Q:00 ctrl:00000281 prop:00000210 02: MASK == ffffffff AND Q:00 ctrl:00000080 prop:ffffffff 03: DPT == 00000003 AND Q:00 ctrl:0000008e prop:00000003 04: DIA == 0a000003 Q:11 ctrl:0000440c prop:0a000003 05: DPT == 00000002 AND Q:00 ctrl:0000008e prop:00000002 06: DIA == 0a000002 Q:09 ctrl:0000240c prop:0a000002 07: DIA == 0a000001 AND Q:00 ctrl:0000008c prop:0a000001 08: DPT == 00000001 CLE Q:01 ctrl:0000060e prop:00000001 ff: MASK >= 00000000 Q:00 ctrl:00000020 prop:00000000 Which looks correct according to the spec but only the first (eth id 252)/last added rule for 10.0.0.3 will ever trigger. As if filer did not treat the AND CLE as cluster start but also kept AND-ing the rules. We found no errata covering this. The fact that nobody noticed (2) or (3) makes me think that this feature is not very widely used and we should just remove it.

When the first slave is added (such as during bootup) the first gratuitous ARP gets dropped. We don't see this drop during a failover. The packet gets dropped in qdisc (noop_enqueue). The fix is to delay the sending of gratuitous ARPs till the bond dev's carrier is present. It can also be worked around by setting num_grat_arp to more than 1.

In case we need to divert reads/writes using the slave MII bus, we may have already fetched a valid PHY interface property from Device Tree, and that mode is used by the PHY driver to make configuration decisions. If we could not fetch the "phy-mode" property, we will assign p->phy_interface to PHY_INTERFACE_MODE_NA, such that we can actually check for that condition as to whether or not we should override the interface value.

When using nested btrees, the top leaves of the top levels contain block addresses for the root of the next tree down. If we shadow a shared leaf node the leaf values (sub tree roots) should be incremented accordingly. This is only an issue if there is metadata sharing in the top levels. Which only occurs if metadata snapshots are being used (as is possible with dm-thinp). And could result in a block from the thinp metadata snap being reused early, thus corrupting the thinp metadata snap.

Once pm_runtime_set_active() gets called, the kernel assumes that given device has already enabled runtime pm and will call pm_runtime_suspend() without matching pm_runtime_resume(). In case of DRM FIMC IPP driver, this will result in calling clk_disable() without respective call to clk_enable().

reqsk_queue_destroy() and reqsk_queue_unlink() should use del_timer_sync() instead of del_timer() before calling reqsk_put(), otherwise we could free a req still used by another cpu. But before doing so, reqsk_queue_destroy() must release syn_wait_lock spinlock or risk a dead lock, as reqsk_timer_handler() might need to take this same spinlock from reqsk_queue_unlink() (called from inet_csk_reqsk_queue_drop()) Fixes: fa76ce73 ("inet: get rid of central tcp/dccp listener timer") Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
