staging: r8188eu: delete driver

2023-03-09T09:06:28Z

Now that the same hardware that the r8188eu driver supported is supported by the real wireless driver rtl8xxxu, the r8188eu driver can be deleted. Also the rtl8xxxu driver supports way more devices, and is a fraction of the overall size, making this a much better overall solution. Thanks to the r8188eu developers and maintainers and reviewers over the years, your work allowed Linux users to use their hardware before the real driver was implemented properly.

staging: rtl8723bs: Pass correct parameters to cfg80211_get_bss()

2023-03-08T16:58:44Z

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.

staging: rtl8723bs: Fix key-store index handling

2023-03-08T16:58:44Z

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.

Pull media updates from Mauro Carvalho Chehab: - Removal of several VB1-only deprecated drivers: cpia2, fsl-viu, meye, stkwebcam, tm6000, vpfe_capture and zr364xx - saa7146 recovered from staging/deprecated. We opted to give ti a chance, and, instead of deprecating it, the intention is to write patches migrating it from VB1 to VB2. - av7110 returned from staging/deprecated/ to staging/ as we're not planning on dropping it any time soon - media controller API has gained experimental support for G_ROUTING and streams API. No drivers use it right now.

Pull driver core updates from Greg KH: "Here is the large set of driver core changes for 6.3-rc1. There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant. We didn't quite make it for this release, but the remaining patches will be finished up for the release after this one, but the groundwork has been laid for this effort. Other than that we have in here: - debugfs memory leak fixes in some subsystems - error path cleanups and fixes for some never-able-to-be-hit codepaths. - cacheinfo rework and fixes - Other tiny fixes, full details are in the shortlog All of these have been in linux-next for a while with no reported problems" [ Geert Uytterhoeven points out that that last sentence isn't true, and that there's a pending report that has a fix that is queued up - Linus ] * tag 'driver-core-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (124 commits) debugfs: drop inline constant formatting for ERR_PTR(-ERROR) OPP: fix error checking in opp_migrate_dentry() debugfs: update comment of debugfs_rename() i3c: fix device.h kernel-doc warnings dma-mapping: no need to pass a bus_type into get_arch_dma_ops() driver core: class: move EXPORT_SYMBOL_GPL() lines to the correct place Revert "driver core: add error handling for devtmpfs_create_node()" Revert "devtmpfs: add debug info to handle()" Revert "devtmpfs: remove return value of devtmpfs_delete_node()" driver core: cpu: don't hand-override the uevent bus_type callback. devtmpfs: remove return value of devtmpfs_delete_node() devtmpfs: add debug info to handle() driver core: add error handling for devtmpfs_create_node() driver core: bus: update my copyright notice driver core: bus: add bus_get_dev_root() function driver core: bus: constify bus_unregister() driver core: bus: constify some internal functions driver core: bus: constify bus_get_kset() driver core: bus: constify bus_register/unregister_notifier() driver core: remove private pointer from struct bus_type ...

Pull staging driver updates from Greg KH: "Here is the "boring" staging driver update for 6.3-rc1.
