2021-03-23drm/i915/display: Eliminate most usage of INTEL_GEN()Matt Roper
Use Coccinelle to convert most of the usage of INTEL_GEN() and IS_GEN() in the display code to use DISPLAY_VER() comparisons instead.

2021-03-23drm/i915: Add DISPLAY_VER() and related macrosMatt Roper
Although we've long referred to platforms by a single "GEN" number, the hardware teams have recommended that we stop doing this since the various component IP blocks are going to start using independent number schemes with varying cadence. To support this, hardware platforms a bit down the road are going to start providing MMIO registers that the driver can read to obtain the "graphics version," "media version," and "display version" without needing to do a PCI ID -> platform -> version translation. Although our current platforms don't yet expose these registers (and the next couple we release probably won't have them yet either), the hardware teams would still like to see us move to this independent numbering scheme now in preparation. For i915 that means we should try to eliminate all usage of INTEL_GEN() throughout our code and instead replace it with separate GRAPHICS_VER(), MEDIA_VER(), and DISPLAY_VER() constructs in the code. For old platforms, these will all usually give the same value for each IP block (aside from a few special cases like GLK which we can no more accurately represent as graphics=9 + display=10), but future platforms will have more flexibility to bump IP version numbers independently. The upcoming ADL-P platform will have a display version of 13 and a graphics version of 12, so let's just the first step of breaking out DISPLAY_VER(), but leaving the rest of INTEL_GEN() untouched for now. For now we'll automatically derive the display version from the platform's INTEL_GEN() value except in cases where an alternative display version is explicitly provided in the device info structure. We also add some helper macros IS_DISPLAY_VER(i915, ver) and IS_DISPLAY_RANGE(i915, from, until) that match the behavior of the existing gen-based macros. However unlike IS_GEN(), we will implement those macros with direct comparisons rather than trying to maintain a mask to help compiler optimization. In practice the optimization winds up not being used in very many places (since the vast majority of our platform checks are of the form "gen >= x") so there is pretty minimal size reduction in the final driver binary[1]. We're also likely going to need to extend these version numbers to non-integer major.minor values at some point in the future, so the mask approach won't work at all once we get to platforms like that.

2021-03-23net: bridge: don't notify switchdev for local FDB addressesVladimir Oltean
As explained in this discussion: https://lore.kernel.org/netdev/20210117193009.io3nungdwuzmo5f7@skbuf/ the switchdev notifiers for FDB entries managed to have a zero-day bug. The bridge would not say that this entry is local: ip link add br0 type bridge ip link set swp0 master br0 bridge fdb add dev swp0 00:01:02:03:04:05 master local and the switchdev driver would be more than happy to offload it as a normal static FDB entry. This is despite the fact that 'local' and non-'local' entries have completely opposite directions: a local entry is locally terminated and not forwarded, whereas a static entry is forwarded and not locally terminated. So, for example, DSA would install this entry on swp0 instead of installing it on the CPU port as it should. There is an even sadder part, which is that the 'local' flag is implicit if 'static' is not specified, meaning that this command produces the same result of adding a 'local' entry: bridge fdb add dev swp0 00:01:02:03:04:05 master I've updated the man pages for 'bridge', and after reading it now, it should be pretty clear to any user that the commands above were broken and should have never resulted in the 00:01:02:03:04:05 address being forwarded (this behavior is coherent with non-switchdev interfaces): https://patchwork.kernel.org/project/netdevbpf/cover/20210211104502.2081443-1-olteanv@gmail.com/ If you're a user reading this and this is what you want, just use: bridge fdb add dev swp0 00:01:02:03:04:05 master static Because switchdev should have given drivers the means from day one to classify FDB entries as local/non-local, but didn't, it means that all drivers are currently broken. So we can just as well omit the switchdev notifications for local FDB entries, which is exactly what this patch does to close the bug in stable trees. For further development work where drivers might want to trap the local FDB entries to the host, we can add a 'bool is_local' to br_switchdev_fdb_call_notifiers(), and selectively make drivers act upon that bit, while all the others ignore those entries if the 'is_local' bit is set.

2021-03-23net/sched: act_ct: clear post_ct if doing ct_clearMarcelo Ricardo Leitner
Invalid detection works with two distinct moments: act_ct tries to find a conntrack entry and set post_ct true, indicating that that was attempted. Then, when flow dissector tries to dissect CT info and no entry is there, it knows that it was tried and no entry was found, and synthesizes/sets key->ct_state = TCA_FLOWER_KEY_CT_FLAGS_TRACKED | TCA_FLOWER_KEY_CT_FLAGS_INVALID; mimicing what OVS does. OVS has this a bit more streamlined, as it recomputes the key after trying to find a conntrack entry for it. Issue here is, when we have 'tc action ct clear', it didn't clear post_ct, causing a subsequent match on 'ct_state -trk' to fail, due to the above. The fix, thus, is to clear it. Reproducer rules: tc filter add dev enp130s0f0np0_0 ingress prio 1 chain 0 \ protocol ip flower ip_proto tcp ct_state -trk \ action ct zone 1 pipe \ action goto chain 2 tc filter add dev enp130s0f0np0_0 ingress prio 1 chain 2 \ protocol ip flower \ action ct clear pipe \ action goto chain 4 tc filter add dev enp130s0f0np0_0 ingress prio 1 chain 4 \ protocol ip flower ct_state -trk \ action mirred egress redirect dev enp130s0f1np1_0 With the fix, the 3rd rule matches, like it does with OVS kernel datapath.

2021-03-23PM: EM: postpone creating the debugfs dir till fs_initcallLukasz Luba
The debugfs directory '/sys/kernel/debug/energy_model' is needed before the Energy Model registration can happen. With the recent change in debugfs subsystem it's not allowed to create this directory at early stage (core_initcall). Thus creating this directory would fail. Postpone the creation of the EM debug dir to later stage: fs_initcall. It should be safe since all clients: CPUFreq drivers, Devfreq drivers will be initialized in later stages.

2021-03-23block: recalculate segment count for multi-segment discards correctlyDavid Jeffery
When a stacked block device inserts a request into another block device using blk_insert_cloned_request, the request's nr_phys_segments field gets recalculated by a call to blk_recalc_rq_segments in blk_cloned_rq_check_limits. But blk_recalc_rq_segments does not know how to handle multi-segment discards. For disk types which can handle multi-segment discards like nvme, this results in discard requests which claim a single segment when it should report several, triggering a warning in nvme and causing nvme to fail the discard from the invalid state.

2021-03-23block: clear GD_NEED_PART_SCAN later in bdev_disk_changedChris Chiu
The GD_NEED_PART_SCAN is set by bdev_check_media_change to initiate a partition scan while removing a block device. It should be cleared after blk_drop_paritions because blk_drop_paritions could return -EBUSY and then the consequence __blkdev_get has no chance to do delete_partition if GD_NEED_PART_SCAN already cleared. It causes some problems on some card readers. Ex. Realtek card reader 0bda:0328 and 0bda:0158. The device node of the partition will not disappear after the memory card removed. Thus the user applications can not update the device mapping correctly.

2021-03-23driver core: clear deferred probe reason on probe retryAhmad Fatoum
When retrying a deferred probe, any old defer reason string should be discarded. Otherwise, if the probe is deferred again at a different spot, but without setting a message, the now incorrect probe reason will remain. This was observed with the i.MX I2C driver, which ultimately failed to probe due to lack of the GPIO driver. The probe defer for GPIO doesn't record a message, but a previous probe defer to clock_get did. This had the effect that /sys/kernel/debug/devices_deferred listed a misleading probe deferral reason.

2021-03-23staging: rtl8192e: Change state information from u16 to u8Atul Gopinathan
The "u16 CcxRmState[2];" array field in struct "rtllib_network" has 4 bytes in total while the operations performed on this array through-out the code base are only 2 bytes. The "CcxRmState" field is fed only 2 bytes of data using memcpy(): (In rtllib_rx.c:1972) memcpy(network->CcxRmState, &info_element->data[4], 2) With "info_element->data[]" being a u8 array, if 2 bytes are written into "CcxRmState" (whose one element is u16 size), then the 2 u8 elements from "data[]" gets squashed and written into the first element ("CcxRmState[0]") while the second element ("CcxRmState[1]") is never fed with any data. Same in file rtllib_rx.c:2522: memcpy(dst->CcxRmState, src->CcxRmState, 2); The above line duplicates "src" data to "dst" but only writes 2 bytes (and not 4, which is the actual size). Again, only 1st element gets the value while the 2nd element remains uninitialized. This later makes operations done with CcxRmState unpredictable in the following lines as the 1st element is having a squashed number while the 2nd element is having an uninitialized random number. rtllib_rx.c:1973: if (network->CcxRmState[0] != 0) rtllib_rx.c:1977: network->MBssidMask = network->CcxRmState[1] & 0x07; network->MBssidMask is also of type u8 and not u16. Fix this by changing the type of "CcxRmState" from u16 to u8 so that the data written into this array and read from it make sense and are not random values. NOTE: The wrong initialization of "CcxRmState" can be seen in the following commit: commit ecdfa44610fa ("Staging: add Realtek 8192 PCI wireless driver") The above commit created a file `rtl8192e/ieee80211.h` which used to have the faulty line. The file has been deleted (or possibly renamed) with the contents copied in to a new file `rtl8192e/rtllib.h` along with additional code in the commit 94a799425eee (tagged in Fixes).

2021-03-23staging: rtl8192e: Fix incorrect source in memcpy()Atul Gopinathan
The variable "info_element" is of the following type: struct rtllib_info_element *info_element defined in drivers/staging/rtl8192e/rtllib.h: struct rtllib_info_element { u8 id; u8 len; u8 data[]; } __packed; The "len" field defines the size of the "data[]" array. The code is supposed to check if "info_element->len" is greater than 4 and later equal to 6. If this is satisfied then, the last two bytes (the 4th and 5th element of u8 "data[]" array) are copied into "network->CcxRmState". Right now the code uses "memcpy()" with the source as "&info_element[4]" which would copy in wrong and unintended information. The struct "rtllib_info_element" has a size of 2 bytes for "id" and "len", therefore indexing will be done in interval of 2 bytes. So, "info_element[4]" would point to data which is beyond the memory allocated for this pointer (that is, at x+8, while "info_element" has been allocated only from x to x+7 (2 + 6 => 8 bytes)). This patch rectifies this error by using "&info_element->data[4]" which correctly copies the last two bytes of "data[]". NOTE: The faulty line of code came from the following commit: commit ecdfa44610fa ("Staging: add Realtek 8192 PCI wireless driver") The above commit created the file `rtl8192e/ieee80211/ieee80211_rx.c` which had the faulty line of code.

This LTE modem (M.2 card) has a bug in its power management: there is some kind of race condition for U3 wake-up between the host and the device. The modem firmware sometimes crashes/locks when both events happen at the same time and the modem fully drops off the USB bus (and sometimes re-enumerates, sometimes just gets stuck until the next reboot). Tested with the modem wired to the XHCI controller on an AMD 3015Ce platform. Without the patch, the modem dropped of the USB bus 5 times in 3 days. With the quirk, it stayed connected for a week while the 'runtime_suspended_time' counter incremented as excepted.
