2023-03-09i2c: Switch .probe() to not take an id parameterUwe Kleine-König
Commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type") introduced a new probe callback to convert i2c init routines to not take an i2c_device_id parameter. Now that all in-tree drivers are converted to the temporary .probe_new() callback, .probe() can be modified to match the desired prototype. Now that .probe() and .probe_new() have the same semantic, they can be defined as members of an anonymous union to save some memory and simplify the core code a bit.

2023-03-09tty: vt: protect KD_FONT_OP_GET_TALL from unbound accessSamuel Thibault
In ioctl(KD_FONT_OP_GET_TALL), userland tells through op->height which vpitch should be used to copy over the font. In con_font_get, we were not checking that it is within the maximum height value, and thus userland could make the vc->vc_sw->con_font_get(vc, &font, vpitch); call possibly overflow the allocated max_font_size bytes, and the copy_to_user(op->data, font.data, c) call possibly read out of that allocated buffer. By checking vpitch against max_font_height, the max_font_size buffer will always be large enough for the vc->vc_sw->con_font_get(vc, &font, vpitch) call (since we already prevent loading a font larger than that), and c = (font.width+7)/8 * vpitch * font.charcount will always remain below max_font_size.

2023-03-09serial: qcom-geni: fix console shutdown hangJohan Hovold
A recent commit added back the calls top stop tx and rx to shutdown() which had previously been removed by commit e83766334f96 ("tty: serial: qcom_geni_serial: No need to stop tx/rx on UART shutdown") in order to be able to use kgdb after stopping the getty. Not only did this again break kgdb, but it also broke serial consoles more generally by hanging TX when stopping the getty during reboot. The underlying problem has been there since the driver was first merged and fixing it is going to be a bit involved so simply stop calling the broken stop functions during shutdown for consoles for now.

REGMAP is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change the use of "depends on REGMAP" to "select REGMAP".

UARTCTRL_SBK is asserted According to LPUART RM, Transmission Complete Flag becomes 0 if queuing a break character by writing 1 to CTRL[SBK], so here need to skip waiting for transmission complete when UARTCTRL_SBK is asserted, otherwise the kernel may stuck here. And actually set_termios() adds transmission completion waiting to avoid data loss or data breakage when changing the baud rate, but we don't need to worry about this when queuing break characters.

2023-03-09dm crypt: avoid accessing uninitialized taskletMike Snitzer
When neither "no_read_workqueue" nor "no_write_workqueue" are enabled, tasklet_trylock() in crypt_dec_pending() may still return false due to an uninitialized state, and dm-crypt will unnecessarily do io completion in io_queue workqueue instead of current context. Fix this by adding an 'in_tasklet' flag to dm_crypt_io struct and initialize it to false in crypt_io_init(). Set this flag to true in kcryptd_queue_crypt() before calling tasklet_schedule(). If set crypt_dec_pending() will punt io completion to a workqueue. This also nicely avoids the tasklet_trylock/unlock hack when tasklets aren't in use.

Some boards might use USB-A female connector for USB ports, however, the port could be connected to a dual-mode USB controller, making it also behaves as a peripheral device if male-to-male cable is connected. In this case, the dts looks like this: &usb0 { status = "okay"; dr_mode = "otg"; usb-role-switch; role-switch-default-mode = "host"; }; After boot, dwc2_ovr_init() sets GOTGCTL to GOTGCTL_AVALOVAL and call dwc2_force_mode() with parameter host=false, which causes inconsistent mode - The hardware is in peripheral mode while the kernel status is in host mode. What we can do now is to call dwc2_drd_role_sw_set() to switch to device mode, and everything should work just fine now, even switching back to none(default) mode afterwards.

2023-03-09usb: gadget: u_audio: don't let userspace block driver unbindAlvin Šipraga
In the unbind callback for f_uac1 and f_uac2, a call to snd_card_free() via g_audio_cleanup() will disconnect the card and then wait for all resources to be released, which happens when the refcount falls to zero. Since userspace can keep the refcount incremented by not closing the relevant file descriptor, the call to unbind may block indefinitely. This can cause a deadlock during reboot, as evidenced by the following blocked task observed on my machine: task:reboot state:D stack:0 pid:2827 ppid:569 flags:0x0000000c Call trace: __switch_to+0xc8/0x140 __schedule+0x2f0/0x7c0 schedule+0x60/0xd0 schedule_timeout+0x180/0x1d4 wait_for_completion+0x78/0x180 snd_card_free+0x90/0xa0 g_audio_cleanup+0x2c/0x64 afunc_unbind+0x28/0x60 ... kernel_restart+0x4c/0xac __do_sys_reboot+0xcc/0x1ec __arm64_sys_reboot+0x28/0x30 invoke_syscall+0x4c/0x110 ... The issue can also be observed by opening the card with arecord and then stopping the process through the shell before unbinding: # arecord -D hw:UAC2Gadget -f S32_LE -c 2 -r 48000 /dev/null Recording WAVE '/dev/null' : Signed 32 bit Little Endian, Rate 48000 Hz, Stereo ^Z[1]+ Stopped arecord -D hw:UAC2Gadget -f S32_LE -c 2 -r 48000 /dev/null # echo gadget.0 > /sys/bus/gadget/drivers/configfs-gadget/unbind (observe that the unbind command never finishes) Fix the problem by using snd_card_free_when_closed() instead, which will still disconnect the card as desired, but defer the task of freeing the resources to the core once userspace closes its file descriptor.

2023-03-09usb: dwc3: gadget: Add 1ms delay after end transfer command without IOCWesley Cheng
Previously, there was a 100uS delay inserted after issuing an end transfer command for specific controller revisions. This was due to the fact that there was a GUCTL2 bit field which enabled synchronous completion of the end transfer command once the CMDACT bit was cleared in the DEPCMD register. Since this bit does not exist for all controller revisions and the current implementation heavily relies on utizling the EndTransfer command completion interrupt, add the delay back in for uses where the interrupt on completion bit is not set, and increase the duration to 1ms for the controller to complete the command. An issue was seen where the USB request buffer was unmapped while the DWC3 controller was still accessing the TRB. However, it was confirmed that the end transfer command was successfully submitted. (no end transfer timeout) In situations, such as dwc3_gadget_soft_disconnect() and __dwc3_gadget_ep_disable(), the dwc3_remove_request() is utilized, which will issue the end transfer command, and follow up with dwc3_gadget_giveback(). At least for the USB ep disable path, it is required for any pending and started requests to be completed and returned to the function driver in the same context of the disable call. Without the GUCTL2 bit, it is not ensured that the end transfer is completed before the buffers are unmapped.

Commit 130a96d698d7 ("usb: typec: ucsi: acpi: Increase command completion timeout value") increased the timeout from 5 seconds to 60 seconds due to issues related to alternate mode discovery. After the alternate mode discovery switch to polled mode the timeout was reduced, but instead of being set back to 5 seconds it was reduced to 1 second. This is causing problems when using a Lenovo ThinkPad X1 yoga gen7 connected over Type-C to a LG 27UL850-W (charging DP over Type-C). When the monitor is already connected at boot the following error is logged: "PPM init failed (-110)", /sys/class/typec is empty and on unplugging the NULL pointer deref fixed earlier in this series happens. When the monitor is connected after boot the following error is logged instead: "GET_CONNECTOR_STATUS failed (-110)". Setting the timeout back to 5 seconds fixes both cases.

2023-03-08net: dsa: mt7530: permit port 5 to work without port 6 on MT7621 SoCVladimir Oltean
The MT7530 switch from the MT7621 SoC has 2 ports which can be set up as internal: port 5 and 6. Arınç reports that the GMAC1 attached to port 5 receives corrupted frames, unless port 6 (attached to GMAC0) has been brought up by the driver. This is true regardless of whether port 5 is used as a user port or as a CPU port (carrying DSA tags). Offline debugging (blind for me) which began in the linked thread showed experimentally that the configuration done by the driver for port 6 contains a step which is needed by port 5 as well - the write to CORE_GSWPLL_GRP2 (note that I've no idea as to what it does, apart from the comment "Set core clock into 500Mhz"). Prints put by Arınç show that the reset value of CORE_GSWPLL_GRP2 is RG_GSWPLL_POSDIV_500M(1) | RG_GSWPLL_FBKDIV_500M(40) (0x128), both on the MCM MT7530 from the MT7621 SoC, as well as on the standalone MT7530 from MT7623NI Bananapi BPI-R2. Apparently, port 5 on the standalone MT7530 can work under both values of the register, while on the MT7621 SoC it cannot. The call path that triggers the register write is: mt753x_phylink_mac_config() for port 6 -> mt753x_pad_setup() -> mt7530_pad_clk_setup() so this fully explains the behavior noticed by Arınç, that bringing port 6 up is necessary. The simplest fix for the problem is to extract the register writes which are needed for both port 5 and 6 into a common mt7530_pll_setup() function, which is called at mt7530_setup() time, immediately after switch reset. We can argue that this mirrors the code layout introduced in mt7531_setup() by commit 42bc4fafe359 ("net: mt7531: only do PLL once after the reset"), in that the PLL setup has the exact same positioning, and further work to consolidate the separate setup() functions is not hindered. Testing confirms that: - the slight reordering of writes to MT7530_P6ECR and to CORE_GSWPLL_GRP1 / CORE_GSWPLL_GRP2 introduced by this change does not appear to cause problems for the operation of port 6 on MT7621 and on MT7623 (where port 5 also always worked) - packets sent through port 5 are not corrupted anymore, regardless of whether port 6 is enabled by phylink or not (or even present in the device tree) My algorithm for determining the Fixes: tag is as follows. Testing shows that some logic from mt7530_pad_clk_setup() is needed even for port 5. Prior to commit ca366d6c889b ("net: dsa: mt7530: Convert to PHYLINK API"), a call did exist for all phy_is_pseudo_fixed_link() ports - so port 5 included. That commit replaced it with a temporary "Port 5 is not supported!" comment, and the following commit 38f790a80560 ("net: dsa: mt7530: Add support for port 5") replaced that comment with a configuration procedure in mt7530_setup_port5() which was insufficient for port 5 to work. I'm laying the blame on the patch that claimed support for port 5, although one would have also needed the change from commit c3b8e07909db ("net: dsa: mt7530: setup core clock even in TRGMII mode") for the write to be performed completely independently from port 6's configuration. Thanks go to Arınç for describing the problem, for debugging and for testing.

2023-03-08staging: rtl8723bs: Pass correct parameters to cfg80211_get_bss()Hans de Goede
To last 2 parameters to cfg80211_get_bss() should be of the enum ieee80211_bss_type resp. enum ieee80211_privacy types, which WLAN_CAPABILITY_ESS very much is not. Fix both cfg80211_get_bss() calls in ioctl_cfg80211.c to pass the right parameters. Note that the second call was already somewhat fixed by commenting out WLAN_CAPABILITY_ESS and passing in 0 instead. This was still not entirely correct though since that would limit returned BSS-es to ESS type BSS-es with privacy on.

2023-03-08staging: rtl8723bs: Fix key-store index handlingHans de Goede
There are 2 issues with the key-store index handling 1. The non WEP key stores can store keys with indexes 0 - BIP_MAX_KEYID, this means that they should be an array with BIP_MAX_KEYID + 1 entries. But some of the arrays where just BIP_MAX_KEYID entries big. While one other array was hardcoded to a size of 6 entries, instead of using the BIP_MAX_KEYID define. 2. The rtw_cfg80211_set_encryption() and wpa_set_encryption() functions index check where checking that the passed in key-index would fit inside both the WEP key store (which only has 4 entries) as well as in the non WEP key stores. This breaks any attempts to set non WEP keys with index 4 or 5. Issue 2. specifically breaks wifi connection with some access points which advertise PMF support. Without this fix connecting to these access points fails with the following wpa_supplicant messages: nl80211: kernel reports: key addition failed wlan0: WPA: Failed to configure IGTK to the driver wlan0: RSN: Failed to configure IGTK wlan0: CTRL-EVENT-DISCONNECTED bssid=... reason=1 locally_generated=1 Fix 1. by using the right size for the key-stores. After this 2. can safely be fixed by checking the right max-index value depending on the used algorithm, fixing wifi not working with some PMF capable APs.

2023-03-08net: microchip: sparx5: fix deletion of existing DSCP mappingsDaniel Machon
Fix deletion of existing DSCP mappings in the APP table. Adding and deleting DSCP entries are replicated per-port, since the mapping table is global for all ports in the chip. Whenever a mapping for a DSCP value already exists, the old mapping is deleted first. However, it is only deleted for the specified port. Fix this by calling sparx5_dcb_ieee_delapp() instead of dcb_ieee_delapp() as it ought to be. Reproduce: // Map and remap DSCP value 63 $ dcb app add dev eth0 dscp-prio 63:1 $ dcb app add dev eth0 dscp-prio 63:2 $ dcb app show dev eth0 dscp-prio dscp-prio 63:2 $ dcb app show dev eth1 dscp-prio dscp-prio 63:1 63:2 <-- 63:1 should not be there Fixes: 8dcf69a64118 ("net: microchip: sparx5: add support for offloading dscp table") Signed-off-by: Daniel Machon <daniel.machon@microchip.com> Reviewed-by: Simon Horman <simon.horman@corigine.com> Signed-off-by: David S.
