2021-04-08mac80211: fix time-is-after bug in mlmeBen Greear1-1/+4
The incorrect timeout check caused probing to happen when it did not need to happen. This in turn caused tx performance drop for around 5 seconds in ath10k-ct driver. Possibly that tx drop is due to a secondary issue, but fixing the probe to not happen when traffic is running fixes the symptom.

2021-04-08mac80211: fix TXQ AC confusionJohannes Berg1-1/+1
Normally, TXQs have txq->tid = tid; txq->ac = ieee80211_ac_from_tid(tid); However, the special management TXQ actually has txq->tid = IEEE80211_NUM_TIDS; // 16 txq->ac = IEEE80211_AC_VO; This makes sense, but ieee80211_ac_from_tid(16) is the same as ieee80211_ac_from_tid(0) which is just IEEE80211_AC_BE. Now, normally this is fine. However, if the netdev queues were stopped, then the code in ieee80211_tx_dequeue() will propagate the stop from the interface (vif->txqs_stopped[]) if the AC 2 (ieee80211_ac_from_tid(txq->tid)) is marked as stopped. On wake, however, __ieee80211_wake_txqs() will wake the TXQ if AC 0 (txq->ac) is woken up. If a driver stops all queues with ieee80211_stop_tx_queues() and then wakes them again with ieee80211_wake_tx_queues(), the ieee80211_wake_txqs() tasklet will run to resync queue and TXQ state. If all queues were woken, then what'll happen is that _ieee80211_wake_txqs() will run in order of HW queues 0-3, typically (and certainly for iwlwifi) corresponding to ACs 0-3, so it'll call __ieee80211_wake_txqs() for each AC in order 0-3. When __ieee80211_wake_txqs() is called for AC 0 (VO) that'll wake up the management TXQ (remember its tid is 16), and the driver's wake_tx_queue() will be called. That tries to get a frame, which will immediately *stop* the TXQ again, because now we check against AC 2, and AC 2 hasn't yet been marked as woken up again in sdata->vif.txqs_stopped[] since we're only in the __ieee80211_wake_txqs() call for AC 0. Thus, the management TXQ will never be started again. Fix this by checking txq->ac directly instead of calculating the AC as ieee80211_ac_from_tid(txq->tid).

2021-04-08rfkill: revert back to old userspace API by defaultJohannes Berg2-15/+72
Recompiling with the new extended version of struct rfkill_event broke systemd in *two* ways: - It used "sizeof(struct rfkill_event)" to read the event, but then complained if it actually got something != 8, this broke it on new kernels (that include the updated API); - It used sizeof(struct rfkill_event) to write a command, but didn't implement the intended expansion protocol where the kernel returns only how many bytes it accepted, and errored out due to the unexpected smaller size on kernels that didn't include the updated API. Even though systemd has now been fixed, that fix may not be always deployed, and other applications could potentially have similar issues. As such, in the interest of avoiding regressions, revert the default API "struct rfkill_event" back to the original size. Instead, add a new "struct rfkill_event_ext" that extends it by the new field, and even more clearly document that applications should be prepared for extensions in two ways: * write might only accept fewer bytes on older kernels, and will return how many to let userspace know which data may have been ignored; * read might return anything between 8 (the original size) and whatever size the application sized its buffer at, indicating how much event data was supported by the kernel. Perhaps that will help avoid such issues in the future and we won't have to come up with another version of the struct if we ever need to extend it again. Applications that want to take advantage of the new field will have to be modified to use struct rfkill_event_ext instead now, which comes with the danger of them having already been updated to use it from 'struct rfkill_event', but I found no evidence of that, and it's still relatively new.

2021-04-08mac80211: clear sta->fast_rx when STA removed from 4-addr VLANSeevalamuthu Mariappan1-1/+3
In some race conditions, with more clients and traffic configuration, below crash is seen when making the interface down. sta->fast_rx wasn't cleared when STA gets removed from 4-addr AP_VLAN interface. The crash is due to try accessing 4-addr AP_VLAN interface's net_device (fast_rx->dev) which has been deleted already. Resolve this by clearing sta->fast_rx pointer when STA removes from a 4-addr VLAN.

2021-04-07selinux: fix race between old and new sidtabOndrej Mosnacek3-37/+145
Since commit 1b8b31a2e612 ("selinux: convert policy read-write lock to RCU"), there is a small window during policy load where the new policy pointer has already been installed, but some threads may still be holding the old policy pointer in their read-side RCU critical sections. This means that there may be conflicting attempts to add a new SID entry to both tables via sidtab_context_to_sid(). See also (and the rest of the thread): https://lore.kernel.org/selinux/CAFqZXNvfux46_f8gnvVvRYMKoes24nwm2n3sPbMjrB8vKTW00g@mail.gmail.com/ Fix this by installing the new policy pointer under the old sidtab's spinlock along with marking the old sidtab as "frozen". Then, if an attempt to add new entry to a "frozen" sidtab is detected, make sidtab_context_to_sid() return -ESTALE to indicate that a new policy has been installed and that the caller will have to abort the policy transaction and try again after re-taking the policy pointer (which is guaranteed to be a newer policy). This requires adding a retry-on-ESTALE logic to all callers of sidtab_context_to_sid(), but fortunately these are easy to determine and aren't that many. This seems to be the simplest solution for this problem, even if it looks somewhat ugly. Note that other places in the kernel (e.g. do_mknodat() in fs/namei.c) use similar stale-retry patterns, so I think it's reasonable.

2021-04-07net: hso: fix null-ptr-deref during tty device unregistrationAnirudh Rayabharam1-21/+12
Multiple ttys try to claim the same the minor number causing a double unregistration of the same device. The first unregistration succeeds but the next one results in a null-ptr-deref. The get_free_serial_index() function returns an available minor number but doesn't assign it immediately. The assignment is done by the caller later. But before this assignment, calls to get_free_serial_index() would return the same minor number. Fix this by modifying get_free_serial_index to assign the minor number immediately after one is found to be and rename it to obtain_minor() to better reflect what it does. Similary, rename set_serial_by_index() to release_minor() and modify it to free up the minor number of the given hso_serial. Every obtain_minor() should have corresponding release_minor() call.

Danielle Ratson says: ==================== Fix link_mode derived params functionality Currently, link_mode parameter derives 3 other link parameters, speed, lanes and duplex, and the derived information is sent to user space. Few bugs were found in that functionality. First, some drivers clear the 'ethtool_link_ksettings' struct in their get_link_ksettings() callback and cause receiving wrong link mode information in user space. And also, some drivers can report random values in the 'link_mode' field and cause general protection fault. Second, the link parameters are only derived in netlink path so in ioctl path, we don't any reasonable values. Third, setting 'speed 10000 lanes 1' fails since the lanes parameter wasn't set for ETHTOOL_LINK_MODE_10000baseR_FEC_BIT. Patch #1 solves the first two problems by removing link_mode parameter and deriving the link parameters in driver instead of ethtool.

2021-04-07ethtool: Remove link_mode param and derive link params from driverDanielle Ratson4-23/+39
Some drivers clear the 'ethtool_link_ksettings' struct in their get_link_ksettings() callback, before populating it with actual values. Such drivers will set the new 'link_mode' field to zero, resulting in user space receiving wrong link mode information given that zero is a valid value for the field. Another problem is that some drivers (notably tun) can report random values in the 'link_mode' field. This can result in a general protection fault when the field is used as an index to the 'link_mode_params' array [1]. This happens because such drivers implement their set_link_ksettings() callback by simply overwriting their private copy of 'ethtool_link_ksettings' struct with the one they get from the stack, which is not always properly initialized. Fix these problems by removing 'link_mode' from 'ethtool_link_ksettings' and instead have drivers call ethtool_params_from_link_mode() with the current link mode. The function will derive the link parameters (e.g., speed) from the link mode and fill them in the 'ethtool_link_ksettings' struct. v3: * Remove link_mode parameter and derive the link parameters in the driver instead of passing link_mode parameter to ethtool and derive it there. v2: * Introduce 'cap_link_mode_supported' instead of adding a validity field to 'ethtool_link_ksettings' struct.

fdt_get_name() returns error values via a parameter pointer instead of in function return. Fix check for this error value in populate_node() and callers of populate_node(). Chasing up the caller tree showed callers of various functions failing to initialize the value of pointer parameters that can return error values. Initialize those values to NULL. The bug was introduced by commit e6a6928c3ea1 ("of/fdt: Convert FDT functions to use libfdt") but this patch can not be backported directly to that commit because the relevant code has further been restructured by commit dfbd4c6eff35 ("drivers/of: Split unflatten_dt_node()") The bug became visible by triggering a crash on openrisc with: commit 79edff12060f ("scripts/dtc: Update to upstream version v1.6.0-51-g183df9e9c2b9") as reported in: https://lore.kernel.org/lkml/[email protected]/ Fixes: 79edff12060f ("scripts/dtc: Update to upstream version v1.6.0-51-g183df9e9c2b9") Reported-by: Guenter Roeck <[email protected]> Signed-off-by: Frank Rowand <[email protected]> Tested-by: Guenter Roeck <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Rob Herring <[email protected]>

Commit 8cdddd182bd7 ("ACPI: processor: Fix CPU0 wakeup in acpi_idle_play_dead()") tried to fix CPU0 hotplug breakage by copying wakeup_cpu0() + start_cpu0() logic from hlt_play_dead()//mwait_play_dead() into acpi_idle_play_dead(). The problem is that these functions are not exported to modules so when CONFIG_ACPI_PROCESSOR=m build fails. The issue could've been fixed by exporting both wakeup_cpu0()/start_cpu0() (the later from assembly) but it seems putting the whole pattern into a new function and exporting it instead is better.
