2021-05-13libertas: register sysfs groups properlyGreg Kroah-Hartman1-24/+4
The libertas driver was trying to register sysfs groups "by hand" which causes them to be created _after_ the device is initialized and announced to userspace, which causes races and can prevent userspace tools from seeing the sysfs files correctly. Fix this up by using the built-in sysfs_groups pointers in struct net_device which were created for this very reason, fixing the race condition, and properly allowing for any error that might have occured to be handled properly.

2021-05-13Revert "libertas: add checks for the return value of sysfs_create_group"Greg Kroah-Hartman1-5/+0
This reverts commit 434256833d8eb988cb7f3b8a41699e2fe48d9332. Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change. The original commit was incorrect, the error needs to be propagated back to the caller AND if the second group call fails, the first needs to be removed. There are much better ways to solve this, the driver should NOT be calling sysfs_create_group() on its own as it is racing userspace and loosing.

Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change. The change being reverted does NOTHING as the caller to this function does not even look at the return value of the call. So the "claim" that this fixed an an issue is not true. It will be fixed up properly in a future patch by propagating the error up the stack correctly.

2021-05-13Revert "rtlwifi: fix a potential NULL pointer dereference"Greg Kroah-Hartman1-5/+0
This reverts commit 765976285a8c8db3f0eb7f033829a899d0c2786e. Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change. This commit is not correct, it should not have used unlikely() and is not propagating the error properly to the calling function, so it should be reverted at this point in time. Also, if the check failed, the work queue was still assumed to be allocated, so further accesses would have continued to fail, meaning this patch does nothing to solve the root issues at all.

2021-05-11ath11k: Clear the fragment cache during key installSriram R3-0/+25
Currently the fragment cache setup during peer assoc is cleared only during peer delete. In case a key reinstallation happens with the same peer, the same fragment cache with old fragments added before key installation could be clubbed with fragments received after. This might be exploited to mix fragments of different data resulting in a proper unintended reassembled packet to be passed up the stack. Hence flush the fragment cache on every key installation to prevent potential attacks (CVE-2020-24587).

2021-05-11ath10k: Validate first subframe of A-MSDU before processing the listSriram R1-4/+57
In certain scenarios a normal MSDU can be received as an A-MSDU when the A-MSDU present bit of a QoS header gets flipped during reception. Since this bit is unauthenticated, the hardware crypto engine can pass the frame to the driver without any error indication. This could result in processing unintended subframes collected in the A-MSDU list. Hence, validate A-MSDU list by checking if the first frame has a valid subframe header. Comparing the non-aggregated MSDU and an A-MSDU, the fields of the first subframe DA matches the LLC/SNAP header fields of a normal MSDU. In order to avoid processing such frames, add a validation to filter such A-MSDU frames where the first subframe header DA matches with the LLC/SNAP header pattern.

2021-05-11ath10k: Fix TKIP Michael MIC verification for PCIeWen Gong1-0/+10
TKIP Michael MIC was not verified properly for PCIe cases since the validation steps in ieee80211_rx_h_michael_mic_verify() in mac80211 did not get fully executed due to unexpected flag values in ieee80211_rx_status. Fix this by setting the flags property to meet mac80211 expectations for performing Michael MIC validation there. This fixes CVE-2020-26141. It does the same as ath10k_htt_rx_proc_rx_ind_hl() for SDIO which passed MIC verification case. This applies only to QCA6174/QCA9377 PCIe.

2021-05-11ath10k: add CCMP PN replay protection for fragmented frames for PCIeWen Gong2-4/+96
PN replay check for not fragmented frames is finished in the firmware, but this was not done for fragmented frames when ath10k is used with QCA6174/QCA6377 PCIe. mac80211 has the function ieee80211_rx_h_defragment() for PN replay check for fragmented frames, but this does not get checked with QCA6174 due to the ieee80211_has_protected() condition not matching the cleared Protected bit case. Validate the PN of received fragmented frames within ath10k when CCMP is used and drop the fragment if the PN is not correct (incremented by exactly one from the previous fragment).

2021-05-07treewide: remove editor modelines and cruftMasahiro Yamada4-32/+0
The section "19) Editor modelines and other cruft" in Documentation/process/coding-style.rst clearly says, "Do not include any of these in source files." I recently receive a patch to explicitly add a new one. Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups. It is even nicer if scripts/checkpatch.pl can check it. If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq updates from Thomas Gleixner: "The usual updates from the irq departement: Core changes: - Provide IRQF_NO_AUTOEN as a flag for request*_irq() so drivers can be cleaned up which either use a seperate mechanism to prevent auto-enable at request time or have a racy mechanism which disables the interrupt right after request. - Get rid of the last usage of irq_create_identity_mapping() and remove the interface. - An overhaul of tasklet_disable(). Most usage sites of tasklet_disable() are in task context and usually in cleanup, teardown code pathes. tasklet_disable() spinwaits for a tasklet which is currently executed. That's not only a problem for PREEMPT_RT where this can lead to a live lock when the disabling task preempts the softirq thread. It's also problematic in context of virtualization when the vCPU which runs the tasklet is scheduled out and the disabling code has to spin wait until it's scheduled back in. There are a few code pathes which invoke tasklet_disable() from non-sleepable context. For these a new disable variant which still spinwaits is provided which allows to switch tasklet_disable() to a sleep wait mechanism. For the atomic use cases this does not solve the live lock issue on PREEMPT_RT. That is mitigated by blocking on the RT specific softirq lock. - The PREEMPT_RT specific implementation of softirq processing and local_bh_disable/enable(). On RT enabled kernels soft interrupt processing happens always in task context and all interrupt handlers, which are not explicitly marked to be invoked in hard interrupt context are forced into task context as well. This allows to protect against softirq processing with a per CPU lock, which in turn allows to make BH disabled regions preemptible. Most of the softirq handling code is still shared. The RT/non-RT specific differences are addressed with a set of inline functions which provide the context specific functionality. The local_bh_disable() / local_bh_enable() mechanism are obviously seperate. - The usual set of small improvements and cleanups Driver changes: - New drivers for Nuvoton WPCM450 and DT 79rc3243x interrupt controllers - Extended functionality for MStar, STM32 and SC7280 irq chips - Enhanced robustness for ARM GICv3/4.1 drivers - The usual set of cleanups and improvements all over the place" * tag 'irq-core-2021-04-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (53 commits) irqchip/xilinx: Expose Kconfig option for Zynq/ZynqMP irqchip/gic-v3: Do not enable irqs when handling spurious interrups dt-bindings: interrupt-controller: Add IDT 79RC3243x Interrupt Controller irqchip: Add support for IDT 79rc3243x interrupt controller irqdomain: Drop references to recusive irqdomain setup irqdomain: Get rid of irq_create_strict_mappings() irqchip/jcore-aic: Kill use of irq_create_strict_mappings() ARM: PXA: Kill use of irq_create_strict_mappings() irqchip/gic-v4.1: Disable vSGI upon (GIC CPUIF < v4.1) detection irqchip/tb10x: Use 'fallthrough' to eliminate a warning genirq: Reduce irqdebug cacheline bouncing kernel: Initialize cpumask before parsing irqchip/wpcm450: Drop COMPILE_TEST irqchip/irq-mst: Support polarity configuration irqchip: Add driver for WPCM450 interrupt controller dt-bindings: interrupt-controller: Add nuvoton, wpcm450-aic dt-bindings: qcom,pdc: Add compatible for sc7280 irqchip/stm32: Add usart instances exti direct event support irqchip/gic-v3: Fix OF_BAD_ADDR error handling irqchip/sifive-plic: Mark two global variables __ro_after_init ...

When the error check in ath9k_hw_read_revisions() was added, it checked for -EIO which is what ath9k_regread() in the ath9k_htc driver uses. However, for plain ath9k, the register read function uses ioread32(), which just returns -1 on error. So if such a read fails, it still gets passed through and ends up as a weird mac revision in the log output. Fix this by changing ath9k_regread() to return -1 on error like ioread32() does, and fix the error check to look for that instead of -EIO.
