2024-05-23nvmet: fix ns enable/disable possible hangSagi Grimberg
When disabling an nvmet namespace, there is a period where the subsys->lock is released, as the ns disable waits for backend IO to complete, and the ns percpu ref to be properly killed. The original intent was to avoid taking the subsystem lock for a prolong period as other processes may need to acquire it (for example new incoming connections). However, it opens up a window where another process may come in and enable the ns, (re)intiailizing the ns percpu_ref, causing the disable sequence to hang. Solve this by taking the global nvmet_config_sem over the entire configfs enable/disable sequence.

2024-05-23r8169: Fix possible ring buffer corruption on fragmented Tx packets.Ken Milmore
An issue was found on the RTL8125b when transmitting small fragmented packets, whereby invalid entries were inserted into the transmit ring buffer, subsequently leading to calls to dma_unmap_single() with a null address. This was caused by rtl8169_start_xmit() not noticing changes to nr_frags which may occur when small packets are padded (to work around hardware quirks) in rtl8169_tso_csum_v2(). To fix this, postpone inspecting nr_frags until after any padding has been applied.

2024-05-23wifi: ath11k: move power type check to ASSOC stage when connecting to 6 GHz APBaochen Qiang
With commit bc8a0fac8677 ("wifi: mac80211: don't set bss_conf in parsing") ath11k fails to connect to 6 GHz AP. This is because currently ath11k checks AP's power type in ath11k_mac_op_assign_vif_chanctx() which would be called in AUTH stage. However with above commit power type is not available until ASSOC stage. As a result power type check fails and therefore connection fails. Fix this by moving power type check to ASSOC stage, also move regulatory rules update there because it depends on power type.

Populate this temporary variable in dma_alloc_coherent() function, and then convert and store the address in the fragment->fragment_tbl[i].ddr_adrs field in the correct format.

2024-05-23idpf: Interpret .set_channels() input differentlyLarysa Zaremba
Unlike ice, idpf does not check, if user has requested at least 1 combined channel. Instead, it relies on a check in the core code. Unfortunately, the check does not trigger for us because of the hacky .set_channels() interpretation logic that is not consistent with the core code. This naturally leads to user being able to trigger a crash with an invalid input. This is how: 1. ethtool -l <IFNAME> -> combined: 40 2. ethtool -L <IFNAME> rx 0 tx 0 combined number is not specified, so command becomes {rx_count = 0, tx_count = 0, combined_count = 40}. 3. ethnl_set_channels checks, if there is at least 1 RX and 1 TX channel, comparing (combined_count + rx_count) and (combined_count + tx_count) to zero. Obviously, (40 + 0) is greater than zero, so the core code deems the input OK. 4. idpf interprets `rx 0 tx 0` as 0 channels and tries to proceed with such configuration. The issue has to be solved fundamentally, as current logic is also known to cause AF_XDP problems in ice [0]. Interpret the command in a way that is more consistent with ethtool manual [1] (--show-channels and --set-channels) and new ice logic. Considering that in the idpf driver only the difference between RX and TX queues forms dedicated channels, change the correct way to set number of channels to: ethtool -L <IFNAME> combined 10 /* For symmetric queues */ ethtool -L <IFNAME> combined 8 tx 2 rx 0 /* For asymmetric queues */ [0] https://lore.kernel.org/netdev/20240418095857.2827-1-larysa.zaremba@intel.com/ [1] https://man7.org/linux/man-pages/man8/ethtool.8.html Fixes: 02cbfba1add5 ("idpf: add ethtool callbacks") Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Reviewed-by: Igor Bagnucki <igor.bagnucki@intel.com> Signed-off-by: Larysa Zaremba <larysa.zaremba@intel.com> Tested-by: Krishneil Singh <krishneil.k.singh@intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2024-05-23ice: Interpret .set_channels() input differentlyLarysa Zaremba
A bug occurs because a safety check guarding AF_XDP-related queues in ethnl_set_channels(), does not trigger. This happens, because kernel and ice driver interpret the ethtool command differently. How the bug occurs: 1. ethtool -l <IFNAME> -> combined: 40 2. Attach AF_XDP to queue 30 3. ethtool -L <IFNAME> rx 15 tx 15 combined number is not specified, so command becomes {rx_count = 15, tx_count = 15, combined_count = 40}. 4. ethnl_set_channels checks, if there are any AF_XDP of queues from the new (combined_count + rx_count) to the old one, so from 55 to 40, check does not trigger. 5. ice interprets `rx 15 tx 15` as 15 combined channels and deletes the queue that AF_XDP is attached to. Interpret the command in a way that is more consistent with ethtool manual [0] (--show-channels and --set-channels).

Currently, the late XenStore init protocol is only triggered properly for the case that HVM_PARAM_STORE_PFN is ~0ULL (invalid). For the case that XenStore interface is allocated but not ready (the connection status is not XENSTORE_CONNECTED), Linux should also wait until the XenStore is set up properly. Introduce a macro to describe the XenStore interface is ready, use it in xenbus_probe_initcall() to select the code path of doing the late XenStore init protocol or not. Since now we have more than one condition for XenStore late init, rework the check in xenbus_probe() for the free_irq(). Take the opportunity to enhance the check of the allocated XenStore interface can be properly mapped, and return error early if the memremap() fails.

2024-05-23net: fec: avoid lock evasion when reading pps_enableWei Fang
The assignment of pps_enable is protected by tmreg_lock, but the read operation of pps_enable is not. So the Coverity tool reports a lock evasion warning which may cause data race to occur when running in a multithread environment. Although this issue is almost impossible to occur, we'd better fix it, at least it seems more logically reasonable, and it also prevents Coverity from continuing to issue warnings.

2024-05-23Revert "ixgbe: Manual AN-37 for troublesome link partners for X550 SFI"Jacob Keller
This reverts commit 565736048bd5f9888990569993c6b6bfdf6dcb6d. According to the commit, it implements a manual AN-37 for some "troublesome" Juniper MX5 switches. This appears to be a workaround for a particular switch. It has been reported that this causes a severe breakage for other switches, including a Cisco 3560CX-12PD-S. The code appears to be a workaround for a specific switch which fails to link in SFI mode. It expects to see AN-37 auto negotiation in order to link. The Cisco switch is not expecting AN-37 auto negotiation. When the device starts the manual AN-37, the Cisco switch decides that the port is confused and stops attempting to link with it. This persists until a power cycle. A simple driver unload and reload does not resolve the issue, even if loading with a version of the driver which lacks this workaround. The authors of the workaround commit have not responded with clarifications, and the result of the workaround is complete failure to connect with other switches. This appears to be a case where the driver can either "correctly" link with the Juniper MX5 switch, at the cost of bricking the link with the Cisco switch, or it can behave properly for the Cisco switch, but fail to link with the Junipir MX5 switch. I do not know enough about the standards involved to clearly determine whether either switch is at fault or behaving incorrectly. Nor do I know whether there exists some alternative fix which corrects behavior with both switches. Revert the workaround for the Juniper switch.

When building ARCH=loongarch defconfig + CONFIG_UNWINDER_ORC=y using LLVM, there is a warning from ld.lld when linking the EFI zboot image due to the use of unreachable() in number() in vsprintf.c: ld.lld: warning: drivers/firmware/efi/libstub/lib.a(vsprintf.stub.o):(.discard.unreachable+0x0): has non-ABS relocation R_LARCH_32_PCREL against symbol '' If the compiler cannot eliminate the default case for any reason, the .discard.unreachable section will remain in the final binary but the entire point of any section prefixed with .discard is that it is only used at compile time, so it can be discarded via /DISCARD/ in a linker script. The asm-generic vmlinux.lds.h includes .discard and .discard.* in the COMMON_DISCARDS macro but that is not used for zboot.lds, as it is not a kernel image linker script. Add .discard and .discard.* to /DISCARD/ in zboot.lds, so that any sections meant to be discarded at link time are not included in the final zboot image. This issue is not specific to LoongArch, it is just the first architecture to select CONFIG_OBJTOOL, which defines annotate_unreachable() as an asm statement to add the .discard.unreachable section, and use the EFI stub.

2024-05-22tracing/treewide: Remove second parameter of __assign_str()Steven Rostedt (Google)
With the rework of how the __string() handles dynamic strings where it saves off the source string in field in the helper structure[1], the assignment of that value to the trace event field is stored in the helper value and does not need to be passed in again. This means that with: __string(field, mystring) Which use to be assigned with __assign_str(field, mystring), no longer needs the second parameter and it is unused. With this, __assign_str() will now only get a single parameter. There's over 700 users of __assign_str() and because coccinelle does not handle the TRACE_EVENT() macro I ended up using the following sed script: git grep -l __assign_str | while read a ; do sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file; mv /tmp/test-file $a; done I then searched for __assign_str() that did not end with ';' as those were multi line assignments that the sed script above would fail to catch. Note, the same updates will need to be done for: __assign_str_len() __assign_rel_str() __assign_rel_str_len() I tested this with both an allmodconfig and an allyesconfig (build only for both).

2024-05-23i3c: master: Enable runtime PM for master controllerMukesh Kumar Savaliya
Enable runtime PM for i3c master node during master registration time. Sometimes i3c client device driver may want to control the PM of the parent (master) to perform the transactions and save the power in an efficient way by controlling the session. Hence device can call PM APIs by passing the parent node. Here, I3C target device when calls pm_runtime_get_sync(dev->parent) couldn't invoke master drivers runtime PM callback registered by the master driver because parent's PM status was disabled in the Master node. Also call pm_runtime_no_callbacks() and pm_suspend_ignore_children() for the master node to not have any callback addition and ignore the children to have runtime PM work just locally in the driver. This should be generic and common change for all i3c devices and should not have any other impact. With these changes, I3C client device works and able to invoke master driver registered runtime PM callbacks.

2024-05-23i3c: master: svc: fix invalidate IBI type and miss call client IBI handlerFrank Li
In an In-Band Interrupt (IBI) handle, the code logic is as follows: 1: writel(SVC_I3C_MCTRL_REQUEST_AUTO_IBI | SVC_I3C_MCTRL_IBIRESP_AUTO, master->regs + SVC_I3C_MCTRL); 2: ret = readl_relaxed_poll_timeout(master->regs + SVC_I3C_MSTATUS, val, SVC_I3C_MSTATUS_IBIWON(val), 0, 1000); ... 3: ibitype = SVC_I3C_MSTATUS_IBITYPE(status); ibiaddr = SVC_I3C_MSTATUS_IBIADDR(status); SVC_I3C_MSTATUS_IBIWON may be set before step 1. Thus, step 2 will return immediately, and the I3C controller has not sent out the 9th SCL yet. Consequently, ibitype and ibiaddr are 0, resulting in an unknown IBI type occurrence and missing call I3C client driver's IBI handler. A typical case is that SVC_I3C_MSTATUS_IBIWON is set when an IBI occurs during the controller send start frame in svc_i3c_master_xfer(). Clear SVC_I3C_MSTATUS_IBIWON before issue SVC_I3C_MCTRL_REQUEST_AUTO_IBI to fix this issue.
