2022-08-10hwmon: (nct6775) Fix platform driver suspend regressionZev Weiss3-2/+5
Commit c3963bc0a0cf ("hwmon: (nct6775) Split core and platform driver") introduced a slight change in nct6775_suspend() in order to avoid an otherwise-needless symbol export for nct6775_update_device(), replacing a call to that function with a simple dev_get_drvdata() instead. As it turns out, there is no guarantee that nct6775_update_device() is ever called prior to suspend. If this happens, the resume function ends up writing bad data into the various chip registers, which results in a crash shortly after resume. To fix the problem, just add the symbol export and return to using nct6775_update_device() as was employed previously.

2022-08-10net:bonding:support balance-alb interface with vlan to bridgeSun Shouxin1-0/+7
In my test, balance-alb bonding with two slaves eth0 and eth1, and then Bond0.150 is created with vlan id attached bond0. After adding bond0.150 into one linux bridge, I noted that Bond0, bond0.150 and bridge were assigned to the same MAC as eth0. Once bond0.150 receives a packet whose dest IP is bridge's and dest MAC is eth1's, the linux bridge will not match eth1's MAC entry in FDB, and not handle it as expected. The patch fix the issue, and diagram as below: eth1(mac:eth1_mac)--bond0(balance-alb,mac:eth0_mac)--eth0(mac:eth0_mac) | bond0.150(mac:eth0_mac) | bridge(ip:br_ip, mac:eth0_mac)--other port Suggested-by: Hu Yadi <huyd12@chinatelecom.cn> Signed-off-by: Sun Shouxin <sunshouxin@chinatelecom.cn> Signed-off-by: David S.

2022-08-10macsec: Fix traffic counters/statisticsClayton Yager1-9/+49
OutOctetsProtected, OutOctetsEncrypted, InOctetsValidated, and InOctetsDecrypted were incrementing by the total number of octets in frames instead of by the number of octets of User Data in frames. The Controlled Port statistics ifOutOctets and ifInOctets were incrementing by the total number of octets instead of the number of octets of the MSDUs plus octets of the destination and source MAC addresses. The Controlled Port statistics ifInDiscards and ifInErrors were not incrementing each time the counters they aggregate were. The Controlled Port statistic ifInErrors was not included in the output of macsec_get_stats64 so the value was not present in ip commands output. The ReceiveSA counters InPktsNotValid, InPktsNotUsingSA, and InPktsUnusedSA were not incrementing. Signed-off-by: Clayton Yager <Clayton_Yager@selinc.com> Signed-off-by: David S.

2022-08-10drm/i915: Sanitycheck PCI BARsPiotr Piórkowski5-0/+46
For proper operation of i915 we need usable PCI GTTMMADDR BAR 0 (1 for GEN2). In most cases we also need usable PCI GFXMEM BAR 2. Let's add functions to check if BARs are set, and that it have a size greater than 0. In case GTTMMADDR BAR, let's validate at the beginning of i915 initialization.

At both suspend and disconnect, we should rather cancel the pending URBs immediately. For the suspend case, the display will be turned off, so it makes no sense to process the rendering.

2022-08-09geneve: fix TOS inheriting for ipv4Matthias May1-4/+8
The current code retrieves the TOS field after the lookup on the ipv4 routing table. The routing process currently only allows routing based on the original 3 TOS bits, and not on the full 6 DSCP bits. As a result the retrieved TOS is cut to the 3 bits. However for inheriting purposes the full 6 bits should be used. Extract the full 6 bits before the route lookup and use that instead of the cut off 3 TOS bits.

2022-08-09dm verity: fix verity_parse_opt_args parsingMike Snitzer1-1/+11
Commit df326e7a0699 ("dm verity: allow optional args to alter primary args handling") introduced a bug where verity_parse_opt_args() wouldn't properly shift past an optional argument's additional params (by ignoring them). Fix this by avoiding returning with error if an unknown argument is encountered when @only_modifier_opts=true is passed to verity_parse_opt_args(). In practice this regressed the cryptsetup testsuite's FEC testing because unknown optional arguments were encountered, wherey short-circuiting ever testing FEC mode. With this fix all of the cryptsetup testsuite's verity FEC tests pass.

2022-08-09dm bufio: simplify DM_BUFIO_CLIENT_NO_SLEEP lockingMike Snitzer1-6/+4
Historically none of the bufio code runs in interrupt context but with the use of DM_BUFIO_CLIENT_NO_SLEEP a bufio client can, see: commit 5721d4e5a9cd ("dm verity: Add optional "try_verify_in_tasklet" feature") That said, the new tasklet usecase still doesn't require interrupts be disabled by bufio (let alone conditionally restore them). Yet with PREEMPT_RT, and falling back from tasklet to workqueue, care must be taken to properly synchronize between softirq and process context, otherwise ABBA deadlock may occur. While it is unnecessary to disable bottom-half preemption within a tasklet, we must consistently do so in process context to ensure locking is in the proper order. Fix these issues by switching from spin_lock_irq{save,restore} to using spin_{lock,unlock}_bh instead. Also remove the 'spinlock_flags' member in dm_bufio_client struct (that can be used unsafely if bufio must recurse on behalf of some caller, e.g. block layer's submit_bio).

2022-08-09NTB: EPF: Tidy up some bounds checksDan Carpenter1-2/+9
This sscanf() is reading from the filename which was set by the kernel so it should be trust worthy. Although the data is likely trust worthy there is some bounds checking but unfortunately, it is not complete or consistent. Additionally, the Smatch static checker marks everything that comes from sscanf() as tainted and so Smatch complains that this code can lead to an out of bounds issue. Let's clean things up and make Smatch happy. The first problem is that there is no bounds checking in the _show() functions. The _store() and _show() functions are very similar so make the bounds checking the same in both. The second issue is that if "win_no" is zero it leads to an array underflow so add an if (win_no <= 0) check for that.
